Bio


Dr. Thomas Weiser is a general, emergency, and trauma surgeon, and surgical intensivist. He treats and cares for injured patients and those with acute surgical emergencies as well as manages critically ill surgical patients in the Intensive Care Unit.

His research is focused on evaluating the role surgical care plays in the delivery of health services in resource poor settings, in particular low and middle income countries. He is interested in barriers to access and provision of surgical care, the quality of surgical services, and outcomes research as well as the science of implementation, how improvements can be made, and how to strengthen compliance with best practices and change behaviors for the better. He also has an interest in domestic policy as it relates to trauma outcomes, trauma systems, insurance coverage and costs of care, and firearm violence.

Dr. Weiser's projects have focused on the quality of surgical care, strategies for improving the safety and reliability of surgical delivery, and team communications. He works closely with Lifebox, a nonprofit focused on improving surgical and anesthetic safety worldwide, where he was previously the Consulting Medical Officer. Lifebox delivers programs throughout the world in combination with local partners including individual professionals, professional societies, hospitals, other NGOs, and ministries of health. Lifebox works with hospitals in Ethiopia, Liberia, Madagascar, India, Honduras, and Nicaragua, amongst others, to improve care and evaluate the impact of our work. A few programs of particular impact are the distribution of low cost devices to improve the safety of care (including pulse oximeters for the routine monitoring of patients undergoing anesthesia and a new surgical headlight program) and Clean Cut, a surgical infection prevention and control program now being introduced in several countries.

From 2006-2009, he was part of the World Health Organization’s Safe Surgery Saves Lives program where he quantified the global volume of surgery and created, implemented, evaluated, and promoted the WHO Surgical Safety Checklist. He has worked with the WHO and the World Bank, and is completing a Gates Grand Challenge Grant-funded study to improve the safety of cesarean section in Ethiopia.

He is a Program Director at Wellcome Leap where he leads Surgery:Assess/Validate/Expand (SAVE).

Clinical Trials


  • Clean-CS: A Program to Improve the Safety of C-section Not Recruiting

    Executive summary: Cesarean delivery, or section (CS), is the single most common surgical procedure performed. Estimates indicate that in low resource settings, CS comprises up to 50% of more of the total volume of operations performed. The World Health Organization recommends national CS rates of between 10-15% to save lives and improve maternal and neonatal outcomes. Population-based work indicates that CS rates of up to 19% are demonstrably related to improved maternal and neonatal survival. However, complications are common, and gynecological and obstetric surgical interventions are associated with high rates of morbidity. In low resource settings, complication rates are particularly high. The intervention being tested is based on a previously developed program called Clean Cut. Clean Cut is an adaptive, multimodal surgical infection prevention program that integrates perioperative process improvement and patient outcomes measurement using process mapping, training and improved management practices, and compliance with critical standards of surgical antisepsis. It was successfully piloted in five surgical departments in Ethiopia, and reduced the relative risk of infection by 35%. This has been adapted specifically for obstetric and gynecological operations and will be evaluated in a cluster randomized stepped wedge trial design in ten maternity hospitals/departments in Ethiopia in order to reduce infections and other complications for women undergoing cesarean delivery and other obstetric and gynecologic operations.

    Stanford is currently not accepting patients for this trial. For more information, please contact Thomas Weiser, xxx-xxxx.

    Abstract

    Surgical infections are a major cause of perioperative morbidity and mortality, particularly in low-resource settings. Clean Cut, a 6-month quality improvement program developed by the global nonprofit organization Lifebox, has demonstrated improvements in postoperative infectious complications. However, the pilot program required intense external programmatic and resource support.To examine the improvement in adherence to infection prevention and control standards and rates of postoperative infections in hospitals in the Clean Cut program after implementation strategies were updated and program execution was refined.This cohort study evaluated and refined the Clean Cut implementation strategy to enhance scalability based on a qualitative study of its pilot phase, including formalizing programmatic and educational materials, building an automated data entry and analysis platform, and reorganizing hospital-based team composition. Clean Cut was introduced from January 1, 2019, to February 28, 2022, in 7 Ethiopian hospitals that had not previously participated in the program. Prospective data initiated on arrival in the operating room were collected, and patients were followed up through hospital discharge and with 30-day follow-up telephone calls.Implementation of the refined Clean Cut program.The primary outcome was surgical site infection (SSI); secondary outcomes were adherence to 6 infection prevention standards, mortality, hospital length of stay, and other infectious complications.A total of 3364 patients (mean [SD] age, 26.5 [38.0] years; 2196 [65.3%] female) from 7 Ethiopian hospitals were studied (1575 at baseline and 1789 after intervention). After controlling for confounders, the relative risk of SSIs was reduced by 34.0% after program implementation (relative risk, 0.66; 95% CI, 0.54-0.81; P < .001). Appropriate Surgical Safety Checklist use increased from 16.3% to 43.0% (P < .001), surgeon hand and patient skin antisepsis improved from 46.0% to 66.0% (P < .001), and timely antibiotic administration improved from 17.8% to 39.0% (P < .001). Surgical instrument (38.7% vs 10.2%), linen sterility (35.5% vs 12.8%), and gauze counting (89.2% vs 82.5%; P < .001 for all comparisons) also improved significantly.A modified implementation strategy for the Clean Cut program focusing on reduced external resource and programmatic input from Lifebox, structured education and training materials, and wider hospital engagement resulted in outcomes that matched our pilot study, with improved adherence to recognized infection prevention standards resulting in a reduction in SSIs. The demonstration of scalability reinforces the value of this SSI prevention program.

  • Impact of Medicaid Expansion and Firearm Legislation on Cost of Firearm Injuries. American journal of preventive medicine Brough, S. C., Tennakoon, L., Spitzer, S. A., Thomas, A., Forrester, J. D., Spain, D. A., Weiser, T. G. 2023

    Abstract

    Firearm injury-related hospitalizations in the United States cost $900 million annually. Prior to the Affordable Care Act (ACA), government insurance programs covered 41% of costs. This study describes the effect of ACA Medicaid expansion and state level firearm legislation on coverage and costs for firearm injuries.This cross-sectional study included 35,854,586 hospitalizations from 27 states in 2013 and 2016. Data analyses were performed in 2022. Firearm injuries were classified by mechanism: assault, unintentional, self-harm, or undetermined. Impact of ACA expansion was determined using difference-in-differences analysis. Differences in per capita costs between states with stronger and weak firearm legislation were compared using univariable and multivariable analyses.The authors identified 31,451 initial firearm injury-related hospitalizations. In states with weak firearm legislation, hospitalization costs per 100,000 residents were higher from unintentional ($25,834; p=0.04) and self-inflicted injuries ($11,550; p=0.02); there were no state-level differences in assault or total per capita firearm-related hospitalization costs. ACA expansion increased government coverage of costs by 15 percentage points (95% CI 3-29) and decreased costs to uninsured/self-pay by 14 percentage points (95% CI 6-21). In 2016, states with weak firearm legislation and no ACA expansion had the highest proportion of hospitalization costs attributed to uninsured/self-pay patients (24%, 95% CI 15-34).ACA expansion increased government coverage of hospitalizations for firearm injuries. Unintentional and self-harm costs were significantly higher for states with weak firearm legislation. States with weak firearm legislation that did not expand Medicaid had highest proportion of uninsured/self-pay patients.Economic & Value Based Evaluations, Level III.

    Abstract

    80% of individuals with cancer will require a surgical procedure, yet little comparative data exist on early outcomes in low-income and middle-income countries (LMICs). We compared postoperative outcomes in breast, colorectal, and gastric cancer surgery in hospitals worldwide, focusing on the effect of disease stage and complications on postoperative mortality.This was a multicentre, international prospective cohort study of consecutive adult patients undergoing surgery for primary breast, colorectal, or gastric cancer requiring a skin incision done under general or neuraxial anaesthesia. The primary outcome was death or major complication within 30 days of surgery. Multilevel logistic regression determined relationships within three-level nested models of patients within hospitals and countries. Hospital-level infrastructure effects were explored with three-way mediation analyses. This study was registered with ClinicalTrials.gov, NCT03471494.Between April 1, 2018, and Jan 31, 2019, we enrolled 15 958 patients from 428 hospitals in 82 countries (high income 9106 patients, 31 countries; upper-middle income 2721 patients, 23 countries; or lower-middle income 4131 patients, 28 countries). Patients in LMICs presented with more advanced disease compared with patients in high-income countries. 30-day mortality was higher for gastric cancer in low-income or lower-middle-income countries (adjusted odds ratio 3·72, 95% CI 1·70-8·16) and for colorectal cancer in low-income or lower-middle-income countries (4·59, 2·39-8·80) and upper-middle-income countries (2·06, 1·11-3·83). No difference in 30-day mortality was seen in breast cancer. The proportion of patients who died after a major complication was greatest in low-income or lower-middle-income countries (6·15, 3·26-11·59) and upper-middle-income countries (3·89, 2·08-7·29). Postoperative death after complications was partly explained by patient factors (60%) and partly by hospital or country (40%). The absence of consistently available postoperative care facilities was associated with seven to 10 more deaths per 100 major complications in LMICs. Cancer stage alone explained little of the early variation in mortality or postoperative complications.Higher levels of mortality after cancer surgery in LMICs was not fully explained by later presentation of disease. The capacity to rescue patients from surgical complications is a tangible opportunity for meaningful intervention. Early death after cancer surgery might be reduced by policies focusing on strengthening perioperative care systems to detect and intervene in common complications.National Institute for Health Research Global Health Research Unit.

  • Global operating theatre distribution and pulse oximetry supply: an estimation from reported data LANCET Funk, L. M., Weiser, T. G., Berry, W. R., Lipsitz, S. R., Merry, A. F., Enright, A. C., Wilson, I. H., Dziekan, G., Gawande, A. A. 2010; 376 (9746): 1055-1061

    Abstract

    Surgery is an essential part of health care, but resources to ensure the availability of surgical services are often inadequate. We estimated the global distribution of operating theatres and quantified the availability of pulse oximetry, which is an essential monitoring device during surgery and a potential measure of operating theatre resources.We calculated ratios of the number of operating theatres to hospital beds in seven geographical regions worldwide on the basis of profiles from 769 hospitals in 92 countries that participated in WHO's safe surgery saves lives initiative. We used hospital bed figures from 190 WHO member states to estimate the number of operating theatres per 100,000 people in 21 subregions throughout the world. To estimate availability of pulse oximetry, we sent surveys to anaesthesia providers in 72 countries selected to ensure a geographically and demographically diverse sample. A predictive regression model was used to estimate the pulse oximetry need for countries that did not provide data.The estimated number of operating theatres ranged from 1·0 (95% CI 0·9-1·2) per 100,000 people in west sub-Saharan Africa to 25·1 (20·9-30·1) per 100,000 in eastern Europe. High-income subregions all averaged more than 14 per 100,000 people, whereas all low-income subregions, representing 2·2 billion people, had fewer than two theatres per 100,000. Pulse oximetry data from 54 countries suggested that around 77,700 (63,195-95,533) theatres worldwide (19·2% [15·2-23·9]) were not equipped with pulse oximeters.Improvements in public-health strategies and monitoring are needed to reduce disparities for more than 2 billion people without adequate access to surgical care.WHO.

  • Standardised metrics for global surgical surveillance LANCET Weiser, T. G., Makary, M. A., Haynes, A. B., Dziekan, G., Berry, W. R., Gawande, A. A. 2009; 374 (9695): 1113-1117

    Abstract

    Public health surveillance relies on standardised metrics to evaluate disease burden and health system performance. Such metrics have not been developed for surgical services despite increasing volume, substantial cost, and high rates of death and disability associated with surgery. The Safe Surgery Saves Lives initiative of WHO's Patient Safety Programme has developed standardised public health metrics for surgical care that are applicable worldwide. We assembled an international panel of experts to develop and define metrics for measuring the magnitude and effect of surgical care in a population, while taking into account economic feasibility and practicability. This panel recommended six measures for assessing surgical services at a national level: number of operating rooms, number of operations, number of accredited surgeons, number of accredited anaesthesia professionals, day-of-surgery death ratio, and postoperative in-hospital death ratio. We assessed the feasibility of gathering such statistics at eight diverse hospitals in eight countries and incorporated them into the WHO Guidelines for Safe Surgery, in which methods for data collection, analysis, and reporting are outlined.

  • A Surgical Safety Checklist to Reduce Morbidity and Mortality in a Global Population. NEW ENGLAND JOURNAL OF MEDICINE Haynes, A. B., Weiser, T. G., Berry, W. R., Lipsitz, S. R., Breizat, A. S., Dellinger, E. P., Herbosa, T., Joseph, S., Kibatala, P. L., Lapitan, M. C., Merry, A. F., Moorthy, K., Reznick, R. K., Taylor, B., Gawande, A. A. 2009; 360 (5): 491-499

    Abstract

    Surgery has become an integral part of global health care, with an estimated 234 million operations performed yearly. Surgical complications are common and often preventable. We hypothesized that a program to implement a 19-item surgical safety checklist designed to improve team communication and consistency of care would reduce complications and deaths associated with surgery.Between October 2007 and September 2008, eight hospitals in eight cities (Toronto, Canada; New Delhi, India; Amman, Jordan; Auckland, New Zealand; Manila, Philippines; Ifakara, Tanzania; London, England; and Seattle, WA) representing a variety of economic circumstances and diverse populations of patients participated in the World Health Organization's Safe Surgery Saves Lives program. We prospectively collected data on clinical processes and outcomes from 3733 consecutively enrolled patients 16 years of age or older who were undergoing noncardiac surgery. We subsequently collected data on 3955 consecutively enrolled patients after the introduction of the Surgical Safety Checklist. The primary end point was the rate of complications, including death, during hospitalization within the first 30 days after the operation.The rate of death was 1.5% before the checklist was introduced and declined to 0.8% afterward (P=0.003). Inpatient complications occurred in 11.0% of patients at baseline and in 7.0% after introduction of the checklist (P<0.001).Implementation of the checklist was associated with concomitant reductions in the rates of death and complications among patients at least 16 years of age who were undergoing noncardiac surgery in a diverse group of hospitals.

  • An estimation of the global volume of surgery: a modelling strategy based on available data LANCET Weiser, T. G., Regenbogen, S. E., Thompson, K. D., Haynes, A. B., Lipsitz, S. R., Berry, W. R., Gawande, A. A. 2008; 372 (9633): 139-144

    Abstract

    Little is known about the amount and availability of surgical care globally. We estimated the number of major operations undertaken worldwide, described their distribution, and assessed the importance of surgical care in global public-health policy.We gathered demographic, health, and economic data for 192 member states of WHO. Data for the rate of surgery were sought from several sources including governmental agencies, statistical and epidemiological organisations, published studies, and individuals involved in surgical policy initiatives. We also obtained per-head total expenditure on health from analyses done in 2004. Major surgery was defined as any intervention occurring in a hospital operating theatre involving the incision, excision, manipulation, or suturing of tissue, usually requiring regional or general anaesthesia or sedation. We created a model to estimate rates of major surgery for countries for which such data were unavailable, then used demographic information to calculate the total worldwide volume of surgery.We obtained surgical data for 56 (29%) of 192 WHO member states. We estimated that 234.2 (95% CI 187.2-281.2) million major surgical procedures are undertaken every year worldwide. Countries spending US$100 or less per head on health care have an estimated mean rate of major surgery of 295 (SE 53) procedures per 100 000 population per year, whereas those spending more than $1000 have a mean rate of 11 110 (SE 1300; p<0.0001). Middle-expenditure ($401-1000) and high-expenditure (>$1000) countries, accounting for 30.2% of the world's population, provided 73.6% (172.3 million) of operations worldwide in 2004, whereas poor-expenditure (

    Abstract

    BACKGROUND: Worldwide, approximately one in six inpatient antibiotic prescriptions are for surgical-infection prophylaxis, including postoperative prophylaxis. The WHO recommends against prolonged postoperative antibiotics to prevent surgical-site infection. However, in many low- and middle-income countries, postoperative antibiotic prophylaxis is common due to perceptions that it protects against surgical-site infection and data informing recommendations against antibiotic administration are largely derived from high-income countries. The aim of this study was to describe postoperative antibiotic-prescribing patterns and related surgical-site infection rates in hospitals in low- and middle-income countries.METHODS: Patients from 19 hospitals in Ethiopia, Madagascar, India, and Bolivia with wound class I and II operations were included. Data on antibiotic administration, indication, surgical-site infection, length of hospital stay, and adherence to perioperative infection-prevention standards were collected by trained personnel. The association between postoperative antibiotic prophylaxis for greater than or equal to 24 h and surgical-site infection was analysed via modified robust Poisson regression, controlling for patient and procedural factors and degree of adherence to perioperative infection-prevention practices.RESULTS: Of 8714 patients, 92.9% received antibiotics for prophylaxis after surgery and 27.7% received antibiotics for greater than or equal to 24 h. Patients receiving postoperative prophylaxis for greater than or equal to 24 h did not have lower surgical-site infection rates (Relative risk 1.09 (95% c.i. 0.89 to 1.33); P = 0.399), but the length of hospital stay was 1.4 days longer (P < 0.001).CONCLUSION: Prolonged postoperative antibiotics did not reduce surgical-site infection, but pervasive use was associated with a longer length of hospital stay, in resource-limited healthcare systems. With the growing threat of antimicrobial resistance, surgical initiatives to implement antimicrobial stewardship programmes in low- and middle-income countries are critical.

  • Thoracic and Lumbar Spine Injury: Evidence-Based Diagnosis, Management, and Outcomes. The American surgeon Gomez, G. I., Li, G. Q., Valido, A. A., Stoner, A. J., Bromley-Dulfano, R. A., Sheira, D., Gonzalez, C. A., Khan, S. I., Choi, J., Zygourakis, C. C., Weiser, T. G. 2023: 31348231216479

    Abstract

    Traumatic thoracolumbar spine injuries are associated with significant morbidity and mortality. Targeted for non-spine specialist trauma surgeons, this systematic scoping review aimed to examine literature for up-to-date evidence on presentation, management, and outcomes of thoracolumbar spine injuries in adult trauma patients.This review was reported using the Preferred Reporting Items for Systematic Reviews and Meta-Analyses checklist. We searched four bibliographic databases: PubMed, EMBASE, Web of Science, and the Cochrane Library. Eligible studies included experimental, observational, and evidence-synthesis articles evaluating patients with thoracic, lumbar, or thoracolumbar spine injury, published in English between January 1, 2010 and January 31, 2021. Studies which focused on animals, cadavers, cohorts with N <30, and pediatric cohorts (age <18 years old), as well as case studies, abstracts, and commentaries were excluded.A total of 2501 studies were screened, of which 326 unique studies were fully text reviewed and twelve aspects of injury management were identified and discussed: injury patterns, determination of injury status and imaging options, considerations in management, and patient quality of life. We found: (1) imaging is a necessary diagnostic tool, (2) no consensus exists for preferred injury characterization scoring systems, (3) operative management should be considered for unstable fractures, decompression, and deformity, and (4) certain patients experience significant burden following injury.In this systematic scoping review, we present the most up-to-date information regarding the management of traumatic thoracolumbar spine injuries. This allows non-specialist trauma surgeons to become more familiar with thoracolumbar spine injuries in trauma patients and provides a framework for their management.

    Abstract

    Enhanced recovery after surgery (ERAS) protocols have largely been incorporated into practice in high-income settings due to proven improvement in perioperative outcomes. We aimed to review the implementation of ERAS protocols and other perioperative optimisation strategies in low- and middle-income countries (LMICs) and their impact on length of hospital stay (LOS).We searched MEDLINE, PubMed, Global Health (CABI), WHO Global Index Medicus, Index Medicus, and Latin American and Caribbean Health Sciences Literature (LILACS) for studies incorporating ERAS or other prehabilitation approaches in LMICs. We conducted a pooled analysis of LOS using a random-effects model to evaluate the impact of such programs. This systematic review was pre-registered on PROSPERO.We screened 1205 studies and included 70 for a full-text review; six were eligible for inclusion and five for quantitative analysis, two of which were randomised controlled trials. ERAS was compared to routine practice in all included studies, while none implemented prehabilitation or other preoperative optimisation strategies. Pooled analysis of 290 patients showed reduced LOS in the ERAS group with a standardised mean difference of -2.18 (95% confidence interval (CI) = -4.13, -.0.05, P < 0.01). The prediction interval was wide (95% CI = -7.85, 3.48) with substantial heterogeneity (I2 = 94%).Perioperative optimisation is feasible in LMICs and appears to reduce LOS, despite high levels of between-study heterogeneity. There is a need for high-quality data on perioperative practice in LMICs and supplementary qualitative analysis to further understand barriers to perioperative optimisation implementation.PROSPERO: CRD42021279053.

  • Pulse oximetry training landscape for healthcare workers in low- and middle-income countries: A scoping review. Journal of global health Peterson, M. E., Docter, S., Ruiz-Betancourt, D. R., Alawa, J., Arimino, S., Weiser, T. G. 2023; 13: 04074

    Abstract

    Background: Pulse oximetry has been used in medical care for decades. Its use quickly became standard of care in high resource settings, with delayed widespread availability and use in lower resource settings. Pulse oximetry training initiatives have been ongoing for years, but a map of the literature describing such initiatives among health care workers in low- and middle-income countries (LMICs) has not previously been conducted. Additionally, the coronavirus disease 2019 (COVID-19) pandemic further highlighted the inequitable distribution of pulse oximetry use and training. We aimed to characterise the landscape of pulse oximetry training for health care workers in LMICs prior to the COVID-19 pandemic as described in the literature.Methods: We systematically searched six databases to identify studies reporting pulse oximetry training among health care workers, broadly defined, in LMICs prior to the COVID-19 pandemic. Two reviewers independently assessed titles and abstracts and relevant full texts for eligibility. Data were charted by one author and reviewed for accuracy by a second. We synthesised the results using a narrative synthesis.Results: A total of 7423 studies were identified and 182 screened in full. A total of 55 training initiatives in 42 countries met inclusion criteria, as described in 66 studies since some included studies reported on different aspects of the same training initiative. Five overarching reasons for conducting pulse oximetry training were identified: 1) anaesthesia and perioperative care, 2) respiratory support programme expansion, 3) perinatal assessment and monitoring, 4) assessment and monitoring of children and 5) assessment and monitoring of adults. Educational programmes varied in their purpose with respect to the types of patients being targeted, the health care workers being instructed, and the depth of pulse oximetry specific training.Conclusions: Pulse oximetry training initiatives have been ongoing for decades for a variety of purposes, utilising a multitude of approaches to equip health care workers with tools to improve patient care. It is important that these initiatives continue as pulse oximetry availability and knowledge gaps remain. Neither pulse oximetry provision nor training alone is enough to bolster patient care, but sustainable solutions for both must be considered to meet the needs of both health care workers and patients.

  • Addressing knowledge gaps in Surgical Safety Checklist use: statistical process control analysis of a surgical quality improvement programme in Ethiopia. The British journal of surgery Nofal, M. R., Starr, N., Negussie Mammo, T., Trickey, A. W., Gebeyehu, N., Koritsanszky, L., Alemu, M., Tara, M., Alemu, S. B., Evans, F., Kahsay, S., Weiser, T. G. 2023

    Abstract

    BACKGROUND: The WHO Surgical Safety Checklist reduces morbidity and mortality after surgery, but uptake remains challenging. In particular, low-income countries have been found to have lower rates of checklist use compared with high-income countries. The aim of this study was to determine the impact of educational workshops on Surgical Safety Checklist use implemented as part of a quality improvement initiative in five hospitals in Ethiopia that had variable experience with the Surgical Safety Checklist.METHODS: From April 2019 to September 2020, each hospital implemented a 6-month surgical quality improvement programme, which included a Surgical Safety Checklist workshop. Statistical process control methodology was used to understand the variation in Surgical Safety Checklist compliance before and after workshops and a time-series analysis was performed using population-averaged generalized estimating equation Poisson regression. Checklist compliance was defined as correctly completing a sign in, timeout, and sign out. Incidence rate ratios of correct checklist use pre- and post-intervention were calculated and the change in mean weekly compliance was predicted.RESULTS: Checklist compliance data were obtained from 2767 operations (1940 (70 per cent) pre-intervention and 827 (30 per cent) post-intervention). Mean weekly checklist compliance improved from 27.3 to 41.2 per cent (mean difference 13.9 per cent, P = 0.001; incidence rate ratio 1.51, P = 0.001). Hospitals with higher checklist compliance at baseline had the greatest overall improvements in compliance, more than 50 per cent over pre-intervention, while low-performing hospitals showed no improvement.CONCLUSION: Surgical Safety Checklist workshops improved checklist compliance in hospitals with some experience with its use. Workshops had little effect in hospitals unfamiliar with the Surgical Safety Checklist, emphasizing the importance of multifactorial interventions and culture-change approaches. In receptive facilities, short workshops can accelerate behaviour change.

    Abstract

    Academic global surgery is a rapidly growing field that aims to improve access to safe surgical care worldwide. However, no universally accepted competencies exist to inform this developing field. A consensus-based approach, with input from a diverse group of experts, is needed to identify essential competencies that will lead to standardization in this field. A task force was set up using snowball sampling to recruit a broad group of content and context experts in global surgical and perioperative care. A draft set of competencies was revised through the modified Delphi process with two rounds of anonymous input. A threshold of 80% consensus was used to determine whether a competency or sub-competency learning objective was relevant to the skillset needed within academic global surgery and perioperative care. A diverse task force recruited experts from 22 countries to participate in both rounds of the Delphi process. Of the n = 59 respondents completing both rounds of iterative polling, 63% were from low- or middle-income countries. After two rounds of anonymous feedback, participants reached consensus on nine core competencies and 31 sub-competency objectives. The greatest consensus pertained to competency in ethics and professionalism in global surgery (100%) with emphasis on justice, equity, and decolonization across multiple competencies. This Delphi process, with input from experts worldwide, identified nine competencies which can be used to develop standardized academic global surgery and perioperative care curricula worldwide. Further work needs to be done to validate these competencies and establish assessments to ensure that they are taught effectively.

    Abstract

    BACKGROUND: High-quality surgical lighting is often lacking in low-resource settings. Commercial surgical headlights are unavailable due to high cost and supply and maintenance challenges. We aimed to understand user needs of a surgical headlight for low-resource settings by evaluating a preselected robust but relatively inexpensive headlight and lighting conditions.METHODS: We observed headlight use by ten surgeons in Ethiopia and six in Liberia. All surgeons completed surveys about their lighting environment and experience using headlight, and were subsequently interviewed. Twelve surgeons completed logbooks on headlight use. We distributed headlights to 48 additional surgeons, and all surgeons were surveyed for feedback.RESULTS: In Ethiopia, five surgeons ranked operating room light quality as poor or very poor; seven delayed or cancelled operations within the last year and five described intraoperative complications due to poor lighting. In Liberia, lighting was rated as "good", however fieldnotes, and interviews noted generator fuel-rationing, and poor lighting conditions. In both countries, the headlight was considered extremely useful. Surgeons recommended nine improvements, including comfort, durability, affordability and availability of multiple rechargeable batteries. Thematic analysis identified factors influencing headlight use, specifications and feedback, and infrastructure challenges.CONCLUSION: Lighting in surveyed operating rooms was poor. Although conditions and need for the headlights differed between Ethiopia and Liberia, headlights were considered highly useful. However, discomfort was a major limiting factor for ongoing use, and the hardest to objectively characterise for specification and engineering purposes. Specific needs for surgical headlights include comfort and durability. Refinement of a fit-for-purpose surgical headlight is ongoing.

    Abstract

    Although international guidelines exist for the prevention of surgical site infections, their implementation in diverse clinical contexts, especially in low and middle-income countries, is challenging due to the lack of available resources and organizational structure of facilities. The goal of this project was to develop a series of video training aids to highlight best practices in surgical infection prevention in hospitals with limited resources and to provide practical solutions to common challenges faced in these settings. Using the validated Clean Cut education framework for infection prevention developed by Lifebox, a charity devoted to improving surgical and anesthetic safety, we partnered with clinicians in one Ethiopian hospital to create six educational videos giving practical guidelines for infection prevention under resource variable conditions. These include: 1) proper use of the WHO Surgical Safety Checklist, 2) hand and skin antisepsis, 3) confirming instrument sterility, 4) maintaining the sterile field, 5) antibiotic prophylaxis, and 6) gauze counting. Gaps in available online educational materials were identified in each of the six areas. Videos were created providing setting-specific education and addressing gaps in existing materials for each of the infection prevention topics. These videos are now integrated into infection prevention curricula through Lifebox in Ethiopia and ongoing data collection to evaluate acceptability and efficacy is ongoing. Surgical education videos on infection prevention topics addressing location-specific resources and workarounds can be useful to hospitals operating in resource-limited settings for training staff and supporting quality and safety efforts in surgery.

    Abstract

    Accurate surveillance of population access to essential surgery is key for strategic healthcare planning. This study aimed to estimate population access to surgical facilities meeting standards for safe surgery equipment, specialized surgical personnel, and bellwether capability, cesarean delivery, emergency laparotomy, and long-bone fracture fixation and to evaluate the validity of using these standards to describe the full breadth of essential surgical care needs in Liberia.An observational study of surgical facilities was conducted in Liberia between 20 September and 8 November 2018. Facility data were combined with geospatial data and analysed in an online visualization platform.Data were collected from 51 of 52 surgical facilities. Nationally, 52.9 per cent of the population (2 392 000 of 4 525 000 people) had 2-h access to their closest surgical facility, whereas 41.1 per cent (1 858 000 people) and 48.6 per cent (2 199 000 people) had 2-h access to a facility meeting the personnel and equipment standards respectively. Six facilities performed all bellwether procedures; 38.7 per cent of the population (1 751 000 people) had 2-h access to one of these facilities. Bellwether-capable facilities were more likely to perform other essential surgical procedures (OR 3.13, 95 per cent c.i. 1.28 to 7.65; P = 0.012). These facilities delivered a median of 13.0 (i.q.r. 11.3-16.5) additional essential procedures.Population access to essential surgery is limited in Liberia; strategies to reduce travel times ought to be part of healthcare policy. Policymakers should also be aware that bellwether capability might not be a valid proxy for the full breadth of essential surgical care in low-income settings.

  • Pulse oximeter provision and training of non-physician anesthetists in Zambia: a qualitative study exploring perioperative care after training. BMC health services research Peterson, M. E., Mattingly, A. S., Merrell, S. B., Asnake, B. M., Ahmed, I., Weiser, T. G. 2022; 22 (1): 1395

    Abstract

    BACKGROUND: Pulse oximetry monitoring is included in the WHO Safe Surgery Checklist and recognized as an essential perioperative safety monitoring device. However, many low resource countries do not have adequate numbers of pulse oximeters available or healthcare workers trained in their use. Lifebox, a nonprofit organization focused on improving anesthetic and surgical safety, has procured and distributed pulse oximeters and relevant educational training in over 100 countries. We aimed to understand qualitatively how pulse oximetry provision and training affected a group of Zambian non-physician anesthetists' perioperative care and what, if any, capacity gaps remain.METHODS: We identified and approached non-physician anesthetists (NPAPs) in Zambia who attended a 2019 Lifebox pulse oximetry training course to participate in a semi-structured interview. Interviews were audio recorded and transcribed. Codes were iteratively derived; the codebook was tested for inter-rater reliability (pooled kappa>0.70). Team-based thematic analysis identified emergent themes on pulse oximetry training and perioperative patient care.RESULTS: Ten of the 35 attendees were interviewed. Two themes emerged concerning pulse oximetry provision and training in discussion with non-physician anesthetists about their experience after training: (1) Impact on Non-Physician Anesthetists and the Healthcare Team and (2) Impact on Perioperative Patient Monitoring. These broad themes were further explored through subthemes. Increased knowledge brought confidence in monitoring and facilitated quick interventions. NPAPs reported improved preoperative assessments and reaffirmed the necessity of having pulse oximetry intraoperatively. However, lack of device availability led to case delays or cancellations. A portable device travelling with the patient to the recovery ward was noted as a major improvement in postoperative care. Pulse oximeters also improved communication between nurses and NPAPs, giving NPAPs confidence in the recovery process. However, this was not always possible, as lack of pulse oximeters and ward staff unfamiliarity with oximetry was commonly reported. NPAPs expressed that wider pulse oximetry availability and training would be beneficial.CONCLUSION: Among a cohort of non-physician anesthetists in Zambia, the provision of pulse oximeters and training was perceived to improve patient care throughout the perioperative timeline. However, capacity and resource gaps remain in their practice settings, especially during transfers of care. NPAPs identified a number of areas where patient care and safety could be improved, including expanding access to pulse oximetry training and provision to ward and nursing staff to ensure the entire healthcare team is aware of the benefits and importance of its use.

    Abstract

    Timing of tracheostomy in patients with COVID-19 has attracted substantial attention. Initial guidelines recommended delaying or avoiding tracheostomy due to the potential for particle aerosolization and theoretical risk to providers. However, early tracheostomy could improve patient outcomes and alleviate resource shortages. This study compares outcomes in a diverse population of hospitalized COVID-19 patients who underwent tracheostomy either "early" (within 14 d of intubation) or "late" (more than 14 d after intubation).International multi-institute retrospective cohort study.Thirteen hospitals in Bolivia, Brazil, Spain, and the United States.Hospitalized patients with COVID-19 undergoing early or late tracheostomy between March 1, 2020, and March 31, 2021.Not applicable.A total of 549 patients from 13 hospitals in four countries were included in the final analysis. Multivariable regression analysis showed that early tracheostomy was associated with a 12-day decrease in time on mechanical ventilation (95% CI, -16 to -8; p < 0.001). Further, ICU and hospital lengths of stay in patients undergoing early tracheostomy were 15 days (95% CI, -23 to -9 d; p < 0.001) and 22 days (95% CI, -31 to -12 d) shorter, respectively. In contrast, early tracheostomy patients experienced lower risk-adjusted survival at 30-day post-admission (hazard ratio, 3.0; 95% CI, 1.8-5.2). Differences in 90-day post-admission survival were not identified.COVID-19 patients undergoing tracheostomy within 14 days of intubation have reduced ventilator dependence as well as reduced lengths of stay. However, early tracheostomy patients experienced lower 30-day survival. Future efforts should identify patients most likely to benefit from early tracheostomy while accounting for location-specific capacity.

    Abstract

    BACKGROUND: We previously developed and pilot tested Clean Cut, a program to prevent postoperative infections by improving compliance with the WHO Surgical Safety Checklist (SSC) and strengthening adherence to infection control practices. This protocol describes the CheckList Expansion for Antisepsis and iNfection Control in Cesarean Section (CLEAN-CS) trial evaluating our program's ability to reduce infections following CS and other obstetric and gynecological operations in Ethiopia.METHODS/DESIGN: CLEAN-CS is a cluster-randomized stepped wedge interventional trial with five clusters (two hospitals per cluster). It aims to assess the impact of Clean Cut on six critical perioperative infection prevention standards including antiseptic practices, antibiotic administration, and routine SCC use. The trial involves baseline data collection followed by Clean Cut training and implementation in each cluster in randomized order. The intervention consists of (1) modifying and implementing the SSC to fit local practices, (2) process mapping each standard, (3) coupling data and processes with site-specific action plans for improvement, and (4) targeted training focused on process gaps. The primary outcome is 30-day CS infection rates; secondary outcomes include other patient-level complications and compliance with standards. Assuming baseline SSI incidence of 12%, an effect size of 25% absolute reduction, and the ability to recruit 80-90 patients per cluster per month, we require a sample of 8100 patients for significance. We will report our study according to CONSORT.DISCUSSION: A cluster-randomized stepped wedge design is well-suited for evaluating this type of surgical safety program. The targeted standards are not in doubt, yet compliance is frequently difficult. Solutions are available and may be recognized by individuals, but teams dedicated to improvement are often lacking. Clean Cut was successfully piloted but requires a more rigorous methodological assessment. We seek to understand the qualities, characteristics, and resources needed to implement the program, the magnitude of effect on processes and outcomes, and to what degree it can enhance compliance with care standards. Challenges include a fraught social and political environment, pandemic travel restrictions, and a limited budget.TRIAL REGISTRATION: ClinicalTrials.gov NCT04812522 (registered on March 23, 2021); Pan-African Clinical Trials Registry PACTR202108717887402 (registered on August 24, 2021).

    Abstract

    Malnutrition is an independent predictor for postoperative complications in low- and middle-income countries (LMICs). We systematically reviewed evidence on the impact of preoperative oral nutrition supplementation (ONS) on patients undergoing gastrointestinal cancer surgery in LMICs. We searched EMBASE, Cochrane Library, Web of Science, Scopus, WHO Global Index Medicus, SciELO, Latin American and Caribbean Health Sciences Literature (LILACS) databases from inception to March 21, 2022 for randomised controlled trials evaluating preoperative ONS in gastrointestinal cancer within LMICs. We evaluated the impact of ONS on all postoperative outcomes using random-effects meta-analysis. Seven studies reported on 891 patients (446 ONS group, 445 control group) undergoing surgery for gastrointestinal cancer. Preoperative ONS reduced all cause postoperative surgical complications (risk ratio (RR) 0.53, 95% CI 0.46-0.60, P<0.001, I2=0%, n=891), infection (0.52, 0.40-0.67, P=0.008, I2=0%, n=570) and all-cause mortality (0.35, 0.26-0.47, P=0.014, I2=0%, n=588). Despite heterogeneous populations and baseline rates, absolute risk ratio (ARR) was reduced for all cause (pooled effect -0.14, -0.22 to -0.06, P=0.006; number needed to treat (NNT) 7) and infectious complications (-0.13, -0.22 to -0.06, P<0.001; NNT 8). Preoperative nutrition in patients undergoing gastrointestinal cancer surgery in LMICs demonstrated consistently strong and robust treatment effects across measured outcomes. However additional higher quality research, with particular focus within African populations, are urgently required.

    Abstract

    The COVID-19 pandemic has strained surgical systems worldwide and placed healthcare providers at risk in their workplace. To protect surgical care providers caring for patients with COVID-19, in May 2020 we developed a COVID-19 Surgical Patient Checklist (C19 SPC), including online training materials, to accompany the World Health Organization Surgical Safety Checklist. In October 2020, an online survey was conducted via partner and social media networks to understand perioperative clinicians' intraoperative practice and perceptions of safety while caring for COVID-19 positive patients and gain feedback on the utility of C19 SPC. Descriptive statistics were used to characterise responses by World Bank income classification. Qualitative analysis was performed to describe respondents' perceptions of C19 SPC and recommended modifications. Respondents included 539 perioperative clinicians from 63 countries. One-third of respondents reported feeling unsafe in their workplace due to COVID-19 with significantly higher proportions in low (39.8%) and lower-middle (33.9%) than higher income countries (15.6%). The most cited concern was the risk of COVID-19 transmission to self, colleagues and family. A large proportion of respondents (65.3%) reported that they had not used C19 SPC, yet 83.8% of these respondents felt it would be useful. Of those who reported that they had used C19 SPC, 62.0% stated feeling safer in the workplace because of its use. Based on survey results, modifications were incorporated into a subsequent version. Our survey findings suggest that perioperative clinicians report feeling unsafe at work during the COVID-19 pandemic. In addition, adjunct tools such as the C19 SPC can help to improve perceived safety.

  • Hospital Costs and Fatality Rates of Traumatic Assaults by Mechanism in the US, 2016-2018. JAMA network open Barry, L. E., Crealey, G. E., Nguyen, N. T., Weiser, T. G., Spitzer, S. A., O'Neill, C. 2022; 5 (6): e2218496

    Abstract

    Importance: Estimates of the total economic cost of firearm violence are important in drawing attention to this public health issue; however, studies that consider violence more broadly are needed to further the understanding of the extent to which such costs can be avoided.Objectives: To estimate the association of firearm assaults with US hospital costs and deaths compared with other assault types.Design, Setting, and Participants: The 2016-2018 US Nationwide Emergency Department Sample and National Inpatient Sample, Healthcare Cost and Utilization Project were used in this cross-sectional study of emergency department (ED) and inpatient admissions for assaults involving a firearm, sharp object, blunt object, or bodily force identified using International Statistical Classification of Diseases, Tenth Revision, Clinical Modification codes. Differences in ED and inpatient costs (2020 US dollars) across mechanisms were estimated using ordinary least-squares regression with and without adjustments for year and hospital, patient, and injury characteristics. The Centers for Disease Control and Prevention underlying cause of death data were used to estimate national death rates and hospital case-fatality rates across mechanisms. Cost analysis used a weighted sample. National death rates and hospital case-fatality rates used US resident death certificates, covering 976 million person-years. Hospital case-fatality rates also used nationally weighted ED records covering 2.7 million admissions. Data analysis was conducted from March 1, 2021, to March 31, 2022.Exposure: The primary exposure was the mechanism used in the assault.Main Outcomes and Measures: Emergency department and inpatient costs per record. National death rates and hospital case-fatality rates.Results: Overall, 2.4 million ED visits and 184 040 inpatient admissions for assault were included. Across all mechanisms, the mean age of the population was 32.7 (95% CI, 32.6-32.9) years in the ED and 36.4 (95% CI, 36.2-36.7) years in the inpatient setting; 41.9% (95% CI, 41.2%-42.5%) were female in the ED, and 19.1% (95% CI, 18.6%-19.6%) of inpatients were female. Most assaults recorded in the ED involved publicly insured or uninsured patients and hospitals in the Southern US. Emergency department costs were $678 (95% CI, $657-$699) for bodily force, $861 (95% CI, $813-$910) for blunt object, $996 (95% CI, $925-$1067) for sharp object, and $1388 (95% CI, $1254-$1522) for firearm assaults. Corresponding inpatient costs were $14 702 (95% CI, $14 178-$15 227) for bodily force, $17 906 (95% CI, $16 888-$18 923) for blunt object, $19 265 (95% CI, $18 475-$20 055) for sharp object, and $34 949 (95% CI, $33 654-$36 244) for firearm assaults. National death rates per 100 000 were 0.04 (95% CI, 0.03-0.04) for bodily force, 0.03 (95% CI, 0.03-0.03) for blunt object, 0.54 (95% CI, 0.52-0.55) for sharp object, and 4.40 (95% CI, 4.36-4.44) for firearm assaults. Hospital case fatality rates were 0.01% (95% CI, 0.009%-0.012%) for bodily force, 0.05% (95% CI, 0.04%-0.06%) for blunt object, 1.05% (95% CI, 1.00%-1.09%) for sharp object, and 15.26% (95% CI, 15.04%-15.49%) for firearm assaults. In regression analysis, ED costs for firearm assaults were 59% to 99% higher than costs for nonfirearm assaults, and inpatient costs were 67% to 118% higher.Conclusions and Relevance: The findings of this study suggest that it may be useful for policies aimed at reducing the costs of firearm violence to consider violence more broadly to understand the extent to which costs can be avoided.

  • A decade of hospital costs for firearm injuries in the United States by region, 2005-2015: government healthcare costs and firearm policies. Trauma surgery & acute care open Spitzer, S. A., Forrester, J. D., Tennakoon, L., Spain, D. A., Weiser, T. G. 2022; 7 (1): e000854

    Abstract

    Firearm injuries are a costly, national public health emergency, and government-sponsored programs frequently pay these hospital costs. Understanding regional differences in firearm injury burden may be useful for crafting appropriate policies, especially with widely varying state gun laws.To estimate the volume of, and hospital costs for, fatal and non-fatal firearm injuries from 2005 to 2015 for each region of the United States and analyze the proportionate cost by payer status.We used the Healthcare Cost and Utilization Project Nationwide Inpatient Sample to identify patients admitted for firearm-related injuries from 2005 to 2015. We converted hospitalization charges to costs, which were inflation-adjusted to 2015 dollars. We used survey weights to create regional estimates. We used the Brady Gun Law to determine significance between firearm restrictiveness and firearm hospitalizations by region.There were a total of 317 479 firearm related admissions over the study period: 52 829 (16.66%), 66 671 (21.0%), 134 008 (42.2%), and 63 972 (20.2%) for the Northeast, Midwest, South, and West respectively, demonstrating high regional variability. In the Northeast, hospital costs were $1.98 billion (13.9% of total), of which 56.0% was covered by government payers; for the Midwest, costs were $153 billion (19.7% of total), 40.4% of which was covered by government payers; in the South costs were highest at $3.2 billion (41.4% of total), but government payers only covered 34.3%; and costs for the West were $1.94 billion (25.0% of total), with government programs covering 41.6% of the cost burden.Hospital admissions and costs for firearm injuries demonstrated wide variation by region, suggesting opportunities for financial savings. As government insurance programs cover 41.5% of costs, tax dollars heavily subsidize the financial burden of firearm injuries and cost recovery options for treating residents injured by firearms should be considered. Injury control strategies have not been well applied to this national public health crisis.Level II, Economic and Value Based Evaluation.

    Abstract

    This article summarizes the consequences of the COVID-19 pandemic, on an international project to tackle antimicrobial resistance (AMR). The research leadership and process, the access to data, and stakeholders were deeply disrupted by the national and international response to the pandemic, including the interruption of healthcare delivery, lockdowns, and quarantines. The key principles to deliver the research through the pandemic were mainly the high degree of interdisciplinary engagement with integrated teams, and equitable partnership across sites with capacity building and leadership training. The level of preexisting collaboration and partnership were also keys to sustaining connections and involvements throughout the pandemic. The pandemic offered opportunities for realigning research priorities. Flexibility in funding timelines and projects inputs are required to accommodate variance introduced by external factors. The current models for research collaboration and funding need to be critically evaluated and redesigned to retain the innovation that was shown to be successful through this pandemic.

  • Building a Trainee-led Research Community to Propel Academic Productivity in Health Services Research. Journal of surgical education Choi, J., Tennakoon, L., Khan, S., Jaramillo, J. D., Rajasingh, C. M., Hakes, N. A., Forrester, J. D., Knowlton, L. M., Nassar, A. K., Weiser, T. G., Spain, D. A. 2022

    Abstract

    Academic productivity is an increasingly important asset for trainees pursuing academic careers. Medical schools and graduate medical education programs offer structured research programs, but providing longitudinal and individualized health services research education remains challenging. Whereas in basic science research, members at multiple training levels support each other within a dedicated community (the laboratory), health services research projects frequently occur within individual faculty-trainee relationships. An optimal match of expertise, availability, and interest may be elusive for an individual mentor-mentee pair. We aimed to share our experience building Surgeons Writing about Trauma (SWAT), a trainee-led research community that propels academic productivity by facilitating peer collaboration and opportunities to transition into independent researchers. We highlight challenges of health services research for trainees, present how structured mentorship and a peer community can address this challenge, and detail SWAT's operational structure to guide replication at peer institutions.

    Abstract

    Preoperative undernutrition is a prognostic indicator for postoperative mortality and morbidity. Evidence suggests that treating undernutrition can improve surgical outcomes. This study explored the provision of nutritional screening, assessment and support on surgical cancer wards in low- and middle-income countries (LMICs). This was a qualitative study and participants took part in one focus group or one individual interview. Data were analysed thematically. There were 34 participants from Ghana, India, the Philippines and Zambia: 24 healthcare professionals (HCPs) and 10 patients. Results showed that knowledge levels and enthusiasm were high in HCPs. Barriers to adequate nutritional support were a lack of provision of ward and kitchen equipment, food and sustainable nutritional supplements. There was variation across countries towards nutritional screening and assessment which seemed to be driven by resources. Many hospitals where resources were scarce focused on the care of individual patients in favour of an integrated systems approach to identify and manage undernutrition. In conclusion, there is scope to improve the efficiency of nutritional management of surgical cancer patients in LMICs through the integration of nutrition assessment and support into routine hospital policies and procedures, moving from case management undertaken by interested personnel to a system-based approach including the whole multidisciplinary team.

  • Clean and Confident: Impact of Sterile Instrument Processing Workshops on Knowledge and Confidence in Five Low- and Middle-Income Countries. Surgical infections Harrell Shreckengost, C. S., Starr, N., Negussie Mammo, T., Gebeyehu, N., Tesfaye, Y., Belayneh, K., Tara, M., Lima, I., Jenkin, K., Fast, C., Weiser, T. G. 1800

    Abstract

    Background: Proper sterilization of surgical instruments is essential for safe surgery, yet re-processing methods in low-resource settings can fall short of standards. Training of Trainers (TOT) workshops in Ethiopia and El Salvador instructed participants in sterile processing concepts and prepared participants to teach others. This study examines participants' knowledge and confidence post-TOT workshop, and moreover discusses subsequent non-TOT workshops and observed sterile processing practices. Methods: Five TOT workshops were conducted between 2018 and 2020 in Ethiopia and Central America. Participant trainers then led nine non-TOT workshops in El Salvador, Guatemala, Honduras, and Nicaragua. Interactive sessions covered instrument cleaning, packaging, disinfection, sterilization, and transportation. Participants completed pre- and post-tests, demonstrated skill competencies, and shared feedback. Peri-operative sterile processing metrics were also observed in Ethiopian hospitals pre- and post-workshops. Results: Ninety-five trainees participated in TOT workshops, whereas 169 participated in non-TOT workshops. Knowledge on a 10-point scale increased substantially after all training sessions (+2.3±2.8, +2.9±1.7, and 2.7±2.5 after Ethiopian, Central American, and non-TOT workshops, respectively; all p<0.05). Scores on tests of sterile processing theory also increased (Ethiopian TOT, +68%±92%; Central American TOT, +26%±20%; p<0.01). Most respondents felt "very confident" about teaching (Ethiopian TOT, 72%; Central American TOT, 83%; non-TOT, 70%), whereas fewer participants felt "very confident" enacting change (Ethiopian TOT, 36%; Central American TOT, 58%; non-TOT, 38%). Reasons included resource scarcity and inadequate support. Nonetheless, observed instrument compliance improved after Ethiopian TOT workshops (odds ratio [OR], 1.47; 95% confidence interval [CI], 1.21-1.78; p<0.01). Conclusions: Sterile processing workshops can improve knowledge, confidence, and sterility compliance in selected low- and middle-income countries. Training of Trainers models empower participants to adapt programs locally, enhancing sterile processing knowledge in different communities. However, national guidelines, physical and administrative resources, and long-term follow-up must improve to ensure effective sterile processing.

  • Operating room efficiency in a low resource setting: a pilot study from a large tertiary referral center in Ethiopia. Patient safety in surgery Negash, S., Anberber, E., Ayele, B., Ashebir, Z., Abate, A., Bitew, S., Derbew, M., Weiser, T. G., Starr, N., Mammo, T. N. 2022; 16 (1): 3

    Abstract

    The operating room (OR) is one of the most expensive areas of a hospital, requiring large capital and recurring investments, and necessitating efficient throughput to reduce costs per patient encounter. On top of increasing costs, inefficient utilization of operating rooms results in prolonged waiting lists, high rate of cancellation, frustration of OR personnel as well as increased anxiety that negatively impacts the health of patients. This problem is magnified in developing countries, where there is a high unmet surgical need. However, no system currently exists to assess operating room utilization in Ethiopia.A prospective study was conducted over a period of 3 months (May 1 to July 31, 2019) in a tertiary hospital. Surgical case start time, end time, room turnover time, cancellations and reason for cancellation were observed to evaluate the efficiency of eight operating rooms.A total of 933 elective procedures were observed during the study period. Of these, 246 were cancelled, yielding a cancellation rate of 35.8%. The most common reasons for cancellation were related to lack of OR time and patient preparation (8.7% and 7.7% respectively). Shortage of facilities (instrument, blood, ICU bed) were causes of cancelation in 7.7%. Start time was delayed in 93.4% (mean 8:56 am ± 52 min) of cases. Last case completion time was early in 47.9% and delayed in 20.6% (mean 2:54 pm ± 156 min). Turnover time was prolonged in 34.5% (mean 25 min ± 49 min). Total operating room utilization ranged from 10.5% to 174%. Operating rooms were underutilized in 42.7% while overutilization was found in 14.6%.We found a high cancellation rate, most attributable to late start times leading to delays for the remainder of cases, and lack of preoperative patient preparation. In a setting with a high unmet burden of surgical disease, OR efficiency must be maximized with improved patient evaluation workflows, adequate OR staffing and commitment to punctual start times. We recommend future quality improvement projects focusing on these areas to increase OR efficiency.

  • The Development and Inclusion of Questions on Surgery in the 2018 Zambia Demographic and Health Survey. Global health, science and practice Juran, S., Moren, S., Santhirapala, V., Roa, L., Makasa, E., Davies, J., Guzman, J. M., Hagander, L., Holmer, H., Shrime, M. G., Weiser, T. G., Meara, J. G., Klug, S. J., Ljungman, D. 1800; 9 (4): 905-914

    Abstract

    BACKGROUND: While primary data on the unmet need for surgery in low- and middle-income countries is lacking, household surveys could provide an entry point to collect such data. We describe the first development and inclusion of questions on surgery in a nationally representative Demographic and Health Survey (DHS) in Zambia.METHOD: Questions regarding surgical conditions were developed through an iterative consultative process and integrated into the rollout of the DHS survey in Zambia in 2018 and administered to a nationwide sample survey of eligible women aged 15-49 years and men aged 15-59 years.RESULTS: In total, 7 questions covering 4 themes of service delivery, diagnosed burden of surgical disease, access to care, and quality of care were added. The questions were administered across 12,831 households (13,683 women aged 15-49 years and 12,132 men aged 15-59 years). Results showed that approximately 5% of women and 2% of men had undergone an operation in the past 5 years. Among women, cesarean delivery was the most common surgery; circumcision was the most common procedure among men. In the past 5 years, an estimated 0.61% of the population had been told by a health care worker that they might need surgery, and of this group, 35% had undergone the relevant procedure.CONCLUSION: For the first time, questions on surgery have been included in a nationwide DHS. We have shown that it is feasible to integrate these questions into a large-scale survey to provide insight into surgical needs at a national level. Based on the DHS design and implementation mechanisms, a country interested in including a set of questions like the one included in Zambia, could replicate this data collection in other settings, which provides an opportunity for systematic collection of comparable surgical data, a vital role in surgical health care system strengthening.

    Abstract

    Any health care system that strives to deliver good health and well-being to its population relies on a trained workforce. The aim of this study was to enumerate surgical provider density, describe operative productivity and assess the association between key surgical system characteristics and surgical provider productivity in Liberia.A nationwide survey of operation theatre logbooks, available human resources and facility infrastructure was conducted in 2018. Surgical providers were counted, and their productivity was calculated based on operative numbers and full-time equivalent positions.A total of 286 surgical providers were counted, of whom 67 were accredited specialists. This translated into a national density of 1.6 specialist providers per 100,000 population. Non-specialist physicians performed 58.3 percent (3607 of 6188) of all operations. Overall, surgical providers performed a median of 1.0 (IQR 0.5-2.7) operation per week, and there were large disparities in operative productivity within the workforce. Most operations (5483 of 6188) were categorized as essential, and each surgical provider performed a median of 2.0 (IQR 1.0-5.0) different types of essential procedures. Surgical providers who performed 7-14 different types of essential procedures were more than eight times as productive as providers who performed 0-1 essential procedure (operative productivity ratio = 8.66, 95% CI 6.27-11.97, P < 0.001).The Liberian health care system struggles with an alarming combination of few surgical providers and low provider productivity. Disaggregated data can provide a high-resolution picture of local challenges that can lead to local solutions.

    Abstract

    INTRODUCTION: We aimed to search the literature for global surgical curricula, assess if published resources align with existing competency frameworks in global health and surgical education, and determine if there is consensus around a fundamental set of competencies for the developing field of academic global surgery.METHODS: We reviewed SciVerse SCOPUS, PubMed, African Medicus Index, African Journals Online (AJOL), SciELO, Latin American and Caribbean Health Sciences Literature (LILACS) and Bioline for manuscripts on global surgery curricula and evaluated the results using existing competency frameworks in global health and surgical education from Consortium of the Universities for Global Health (CUGH) and Accreditation Council for Graduate Medical Education (ACGME) professional competencies.RESULTS: Our search generated 250 publications, of which 18 were eligible: (1) a total of 10 reported existing competency-based curricula that were concurrent with international experiences, (2) two reported existing pre-departure competency-based curricula, (3) six proposed theoretical competency-based curricula for future global surgery education. All, but one, were based in high-income countries (HICs) and focused on the needs of HIC trainees. None met all 17 competencies, none cited the CUGH competency on "Health Equity and Social Justice" and only one mentioned "Social and Environmental Determinants of Health." Only 22% (n=4) were available as open-access.CONCLUSION: Currently, there is no universally accepted set of competencies on the fundamentals of academic global surgery. Existing literature are predominantly by and for HIC institutions and trainees. Current frameworks are inadequate for this emerging academic field. The field needs competencies with explicit input from LMIC experts to ensure creation of educational resources that are accessible and relevant to trainees from around the world.

    Abstract

    BACKGROUND: Many US general surgery residents are interested in global surgery, but their competence with key procedures is unknown.METHODS: Using a registry managed by the Society for Improving Medical Professional Learning (SIMPL), we extracted longitudinal operative performance ratings data for a national cohort of US general surgery residents. Operative performance at the time of graduation was estimated via a Bayesian generalized linear mixed model.RESULTS: Operative performance ratings for 12,976 procedures performed by 1584 residents in 52 general surgery programs were analyzed. These spanned 17 of 31 (55%) procedures deemed important for global surgical practice. For these procedures, the probability of a graduating resident being deemed competent to perform a procedure was 0.95 (95% confidence interval 0.86-1.00) but was less than 0.9 for 3 observed procedures.CONCLUSION: Our results highlight gaps in the preparedness of US general surgery trainees to perform procedures deemed most important for global surgery settings.

    Abstract

    We aimed to define a globally applicable list of surgical procedures, or "basket," which could represent a health system's capacity to provide surgical care and standardize global surgical measurement.Six indicators have been proposed to assess access to safe, affordable, timely surgical and anesthesia care, with a focus on laparotomy, cesarean section, and treatment of open fracture. However, comparability, particularly for these procedures, has been limited by a lack of definitional clarity and their overly broad scope.We conducted a 3 round international expert Delphi exercise between April and June 2019 using REDCap to identify a set of procedures representative of surgical capacity. To be included, procedures had to be important for treating common conditions, well-defined, and impactful (ie, well-recognized clinical or functional benefit). Procedures were eliminated or prioritized in each round, and those noted as "extremely" or "very important" by ≥50% of respondents in round 3 were included in the final "basket."Altogether 331 respondents from 78 countries participated in the Delphi process. A final basket of 32 procedures representing disease categories in trauma, cancer, congenital anomalies, maternal/reproductive health, aging, and infection were identified for inclusion to assess surgical capacity.This surgical basket facilitates a more standardized assessment of a country's surgical system. Further testing and refinement will likely be needed, but this basket can be used immediately to guide ongoing monitoring and evaluation of global surgery capacities to improve and strengthen surgery and anesthesia care.

    Abstract

    Indicators to evaluate progress towards timely access to safe surgical, anaesthesia, and obstetric (SAO) care were proposed in 2015 by the Lancet Commission on Global Surgery. These aimed to capture access to surgery, surgical workforce, surgical volume, perioperative mortality rate, and catastrophic and impoverishing financial consequences of surgery. Despite being rapidly taken up by practitioners, data points from which to derive the indicators were not defined, limiting comparability across time or settings. We convened global experts to evaluate and explicitly define-for the first time-the indicators to improve comparability and support achievement of 2030 goals to improve access to safe affordable surgical and anaesthesia care globally.The Utstein process for developing and reporting guidelines through a consensus building process was followed. In-person discussions at a 2-day meeting were followed by an iterative process conducted by email and virtual group meetings until consensus was reached. The meeting was held between June 16 to 18, 2019; discussions continued until August 2020. Participants consisted of experts in surgery, anaesthesia, and obstetric care, data science, and health indicators from high-, middle-, and low-income countries. Considering each of the 6 indicators in turn, we refined overarching descriptions and agreed upon data points needed for construction of each indicator at current time (basic data points), and as each evolves over 2 to 5 (intermediate) and >5 year (full) time frames. We removed one of the original 6 indicators (one of 2 financial risk protection indicators was eliminated) and refined descriptions and defined data points required to construct the 5 remaining indicators: geospatial access, workforce, surgical volume, perioperative mortality, and catastrophic expenditure. A strength of the process was the number of people from global institutes and multilateral agencies involved in the collection and reporting of global health metrics; a limitation was the limited number of participants from low- or middle-income countries-who only made up 21% of the total attendees.To track global progress towards timely access to quality SAO care, these indicators-at the basic level-should be implemented universally as soon as possible. Intermediate and full indicator sets should be achieved by all countries over time. Meanwhile, these evolutions can assist in the short term in developing national surgical plans and collecting more detailed data for research studies.

    Abstract

    As surgical systems are forced to adapt and respond to new challenges, so should the patient safety tools within those systems. We sought to determine how the WHO SSC might best be adapted during the COVID-19 pandemic.18 Panelists from five continents and multiple clinical specialties participated in a three-round modified Delphi technique to identify potential recommendations, assess agreement with proposed recommendations and address items not meeting consensus.From an initial 29 recommendations identified in the first round, 12 were identified for inclusion in the second round. After discussion of recommendations without consensus for inclusion or exclusion, four additional recommendations were added for an eventual 16 recommendations. Nine of these recommendations were related to checklist content, while seven recommendations were related to implementation.This multinational panel has identified 16 recommendations for sites looking to use the surgical safety checklist during the COVID-19 pandemic. These recommendations provide an example of how the SSC can adapt to meet urgent and emerging needs of surgical systems by targeting important processes and encouraging critical discussions.

    Abstract

    Patients hospitalized with COVID-19 are at risk of developing hypoxic respiratory failure and often require prolonged mechanical ventilation. Indication and timing to perform tracheostomy is controversial in patients with COVID-19.This was a single-institution retrospective review of tracheostomies performed on patients admitted for COVID-19 between April 8, 2020 and August 1, 2020 using a modified percutaneous tracheostomy technique to minimize hypoxia and aerosolization.Twelve tracheostomies were performed for COVID-related respiratory failure. Median patient age was 54 years (range: 36-76) and 9 (75%) were male. Median time to tracheostomy was 17 days (range: 10-27), and 5 (42%) patients had failed attempts at extubation prior to tracheostomy. There were no intraprocedural complications, including hypoxia. Post-tracheostomy bleeding was noted in two patients. Eight (67%) patients have been discharged at the time of this study, and there were four patient deaths unrelated to tracheostomy placement. No healthcare worker transmissions resulted from participating in the tracheostomy procedure.A modified percutaneous tracheostomy is feasible and can be safely performed in patients infected with COVID-19.Level V, case series.

  • The Lifebox Surgical Headlight Project: engineering, testing, and field assessment in a resource-constrained setting British Journal of Surgery Starr, N., et al 2020: 1751-1761

    Abstract

    Poor surgical lighting represents a major patient safety issue in low-income countries. This study evaluated device performance and undertook field assessment of high-quality headlights in Ethiopia to identify critical attributes that might improve safety and encourage local use.Following an open call for submissions (December 2018 to January 2019), medical and technical (non-medical) headlights were identified for controlled specification testing on 14 prespecified parameters related to light quality/intensity, mounting and battery performance, including standardized illuminance measurements over time. The five highest-performing devices (differential illumination, colour rendering, spot size, mounting and battery duration) were distributed to eight Ethiopian surgeons working in resource-constrained facilities. Surgeons evaluated the devices in operating rooms, and in a comparative session rated each headlight in terms of performance and willingness to purchase.Of 25 submissions, eight headlights (6 surgical and 2 technical) met the criteria for full specification testing. Scores ranged from 8 to 12 (of 14), with differential performance in lighting, mounting and battery domains. Only two headlights met the illuminance parameters of more than 35 000 lux during initial testing, and no headlight satisfied all minimum specifications. Of the five headlights evaluated in Ethiopia, daily operation logbooks noted variability in surgeons' opinions of lighting quality (6-92 per cent) and spot size (0-92 per cent). Qualitative interviews also yielded important feedback, including preference for easy transport. Surgeons sought high quality with price sensitivity (using out-of-pocket funds) and identified the least expensive but high-functioning device as their first choice.No device satisfied all the predetermined specifications, and large price discrepancies were critical factors leading surgeons' choices. The favoured device is undergoing modification by the manufacturer based on design feedback so an affordable, high-quality surgical headlight crafted specifically for the needs of resource-constrained settings can be used to improve surgical safety.

  • Clean Cut (adaptive, multimodal surgical infection prevention programme) for low-resource settings: a prospective quality improvement study BRITISH JOURNAL OF SURGERY Forrester, J. A., Starr, N., Negussie, T., Schaps, D., Adem, M., Alemu, S., Amenu, D., Gebeyehu, N., Habteyohannes, T., Jiru, F., Tesfaye, A., Wayessa, E., Chen, R., Trickey, A., Bitew, S., Bekele, A., Weiser, T. G. 2020: 727-734

    Abstract

    Clean Cut is an adaptive, multimodal programme to identify improvement opportunities and safety changes in surgery by enhancing outcomes surveillance, closing gaps in surgical infection prevention standards, and strengthening underlying processes of care. Surgical-site infections (SSIs) are common in low-income countries, so this study assessed a simple intervention to improve perioperative infection prevention practices in one.Clean Cut was implemented in five hospitals in Ethiopia from August 2016 to October 2018. Compliance data were collected from the operating room focused on six key perioperative infection prevention standards. Process-mapping exercises were employed to understand barriers to compliance and identify locally driven improvement opportunities. Thirty-day outcomes were recorded on patients for whom intraoperative compliance information had been collected.Compliance data were collected from 2213 operations (374 at baseline and 1839 following process improvements) in 2202 patients. Follow-up was completed in 2159 patients (98·0 per cent). At baseline, perioperative teams complied with a mean of only 2·9 of the six critical perioperative infection prevention standards; following process improvement changes, compliance rose to a mean of 4·5 (P < 0·001). The relative risk of surgical infections after Clean Cut implementation was 0·65 (95 per cent c.i. 0·43 to 0·99; P = 0·043). Improved compliance with standards reduced the risk of postoperative infection by 46 per cent (relative risk 0·54, 95 per cent c.i. 0·30 to 0·97, for adherence score 3-6 versus 0-2; P = 0·038).The Clean Cut programme improved infection prevention standards to reduce SSI without infrastructure expenses or resource investments.

  • Impact of surgical infrastructure and personnel on volume and availability of essential surgical procedures in Liberia BJS OPEN Adde, H. A., van Duinen, A. J., Oghogho, M. D., Dunbar, N. K., Tehmeh, L. G., Hampaye, T. C., Salvesen, O., Weiser, T. G., Bolkan, H. A. 2020; 4 (6): 1246-1255

    Abstract

    Essential surgical procedures rank among the most cost-effective of all healthcare interventions. The aim of this study was to enumerate surgical volumes in Liberia, quantify surgical infrastructure, personnel and availability of essential surgical procedures, describe surgical facilities, and assess the influence of human resources and infrastructure on surgical volumes.An observational countrywide survey was done in Liberia between 20 September and 8 November 2018. All healthcare facilities performing surgical procedures requiring general, regional or local anaesthesia in an operating theatre between September 2017 and August 2018 were eligible for inclusion. Information on facility infrastructure and human resources was collected by interviewing key personnel. Data on surgical volumes were extracted from operating theatre log books.Of 70 healthcare facilities initially identified as possible surgical facilities, 52 confirmed operative capacity and were eligible for inclusion; all but one shared surgical data. A national surgical volume of 462 operations per 100 000 population was estimated. The median hospital offered nine of 26 essential surgical procedures. Unequal distributions of surgical infrastructure, personnel, and essential surgical procedures were identified between facilities. In multivariable regression analysis, surgical human resources (β = 0·60, 95 per cent c.i. 0·34 to 0·87; P < 0·001) and infrastructure (β = 0·03, 0·02 to 0·04; P < 0·001) were found to be strongly associated with operative volumes.The availability of essential surgical procedures in Liberia is extremely low. Descriptive tools can quantify inequalities, guide resource allocation, and highlight rational investment areas.

    Abstract

    BACKGROUND: The Surgical Safety Checklist (SSC) has been shown to reduce perioperative complications across global health systems. We sought to assess perceptions of the SSC and suggestions for its improvement among medical students, trainees, and early career providers.METHODS: From July to September 2019, a survey assessing perceptions of the SSC was disseminated through InciSioN, the International Student Surgical Network comprising medical students, trainees, and early career providers pursuing surgery. Individuals with ≥2years of independent practice after training were excluded. Respondents were categorized according to any clinical versus solely non-clinical SSC exposure. Logistic regression was used to evaluate associations between clinical/non-clinical exposure and promoting future use of the SSC, adjusting for potential confounders/mediators: training level, human development index, and first perceptions of the SSC. Thematic analysis was conducted on suggestions for SSC improvement.RESULTS: Respondent participation rate was 24%. Three hundred and eighteen respondents were included in final analyses; 215 (67%) reported clinical exposure and 190 (60%) were promoters of future SSC use. Clinical exposure was associated with greater odds of promoting future SSC use (aOR 1.81 95% CI [1.03-3.19], p=0.039). A greater proportion of promoters reported "Improved Operating Room Communication" as a goal of the SSC (0.21 95% CI [0.15-0.27]-vs.-0.12 [0.06-0.17], p=0.031), while non-promoters reported the SSC goals were "Not Well Understood" (0.08 95% CI [0.03-0.12]-vs.-0.03 [0.01-0.05], p=0.032). Suggestions for SSC improvement emphasized context-specific adaptability and earlier formal training.CONCLUSIONS: Clinical exposure to the SSC was associated with promoting its future use. Earlier formal clinical training may improve perceptions and future use among medical students, trainees, and early career providers.

  • Value and Feasibility of Telephone Follow-Up in Ethiopian Surgical Patients. Surgical infections Starr, N., Gebeyehu, N., Tesfaye, A., Forrester, J. A., Bekele, A., Bitew, S., Wayessa, E., Weiser, T. G., Negussie, T. 2020

    Abstract

    Background: Surgical site infections (SSIs) represent a major cause of morbidity and mortality in Ethiopia. Lack of post-discharge follow-up, including identification of SSIs, is a barrier to continued patient care, often because of financial and travel constraints. As part of a surgical quality improvement initiative, we aimed to assess patient outcomes at 30 days post-operative with a telephone call. Patients and Methods: We conducted mobile telephone follow-up as part of Lifebox's ongoing Clean Cut program, which aims to improve compliance with intra-operative infection prevention standards. One urban tertiary referral hospital and one rural district general hospital in Ethiopia were included in this phase of the study; hospital nursing staff called patients at 30 days post-operative inquiring about signs of SSIs, health-care-seeking behavior, and treatments provided if patients had any healthcare encounters since discharge. Results: A total of 701 patients were included; overall 77% of patients were reached by telephone call after discharge. The rural study site reached 362 patients (87%) by telephone; the urban site reached 176 patients (62%) (p<0.001). Of the 39 SSIs identified, 19 (49%) were captured as outpatient during the telephone follow-up (p<0.001); 22 (34%) of all complications were captured following discharge (p<0.001). Telephone follow-up improved from 65%-78% in the first half of project implementation to 77%-89% in the second half of project implementation. Conclusion: Telephone follow-up after surgery in Ethiopia is feasible and valuable, and identified nearly half of all SSIs and one-third of total complications in our cohort. Follow-up improved over the course of the program, likely indicating a learning curve that, once overcome, is a more accurate marker of its practicability. Given the increasing use of mobile telephones in Ethiopia and ease of implementation, this model could be practical in other low-resource surgical settings.

  • Impact of the Affordable Care Act Insurance Marketplaces on Out-of-Pocket Spending Among Surgical Patients. Annals of surgery Liu, C., Maggard-Gibbons, M., Weiser, T. G., Morris, A. M., Tsugawa, Y. 2020

    Abstract

    OBJECTIVE: To evaluate the association between the introduction of the Affordable Care Act (ACA) Health Insurance Marketplaces ("Marketplaces") and financial protection for patients undergoing surgery.BACKGROUND: The ACA established Marketplaces through which individuals could purchase subsidized insurance coverage. However, the effect of these Marketplaces on surgical patients' healthcare spending remains largely unknown.METHODS: We analyzed a nationally representative sample of adults aged 19-64 who underwent surgery in 2010-2017, using the Medical Expenditure Panel Survey. Low-income patients eligible for cost-sharing and premium subsidies in the Marketplaces [income 139%-250% federal poverty level (FPL)] and middle-income patients eligible only for premium subsidies (251%-400% FPL) were compared to high-income controls ineligible for subsidies (>400% FPL) using a quasi-experimental difference-in-differences approach. We evaluated 3 main outcomes: (1) out-of-pocket spending, (2) premium contributions, and (3) likelihood of experiencing catastrophic expenditures, defined as out-of-pocket plus premium spending exceeding 19.5% of family income.RESULTS: Our sample included 5450 patients undergoing surgery, representing approximately 69 million US adults. Among low-income patients, Marketplace implementation was associated with $601 lower [95% confidence interval (CI): -$1169 to -$33; P = 0.04) out-of-pocket spending; $968 lower (95% CI: -$1652 to -$285; P = 0.006) premium spending; and 34.6% lower probability (absolute change: -8.3 percentage points; 95% CI: -14.9 to -1.7; P = 0.01) of catastrophic expenditures. We found no evidence that health expenditures changed for middle-income surgical patients.CONCLUSIONS: The ACA's insurance Marketplaces were associated with improved financial protection among low-income surgical patients eligible for both cost-sharing and premium subsidies, but not in middle-income patients eligible for only premium subsidies.

    Abstract

    Trauma is an expensive and unpredictable source of out-of-pocket spending for American families. The Patient Protection and Affordable Care Act (ACA) sought to improve financial protection by expanding health insurance coverage, but its association with health care spending for patients with traumatic injury remains largely unknown.To evaluate the association of ACA implementation with out-of-pocket spending, premiums, and catastrophic health expenditures (CHE) among adult patients with traumatic injury.Data from a nationally representative sample of US adults aged 19 to 64 years who had a hospital stay or emergency department visit for a traumatic injury from January 2010 to December 2017 were analyzed using the Medical Expenditure Panel Survey. Multivariable generalized linear models were used to evaluate changes in spending after ACA implementation. Additionally, 4 income subgroups were evaluated based on ACA thresholds for program eligibility: lowest-income patients (earning 138% or less of the federal poverty level [FPL]), low-income patients (earning 139% to 250% of the FPL), middle-income patients (earning 251% to 400% of the FPL), and high-income patients (earning more than 400% of the FPL). Data were analyzed from February to December 2019.Implementation of the ACA, beginning January 1, 2014.Out-of-pocket spending, premium spending, out-of-pocket plus premium spending, and likelihood of experiencing CHE, defined as out-of-pocket plus premium spending exceeding 19.5% of family income.Of the 6288 included patients, 2995 (weighted percentage, 51.3%) were male, and the mean (SD) age was 41.4 (12.8) years. Implementation of the ACA was associated with 31% lower odds of CHE (adjusted odds ratio, 0.69; 95% CI, 0.54 to 0.87; P = .002). Changes were greatest in lowest-income patients, who experienced 30% lower out-of-pocket spending (adjusted percentage change, -30.4%; 95% CI, -46.6% to -9.4%; P = .01), 26% lower out-of-pocket plus premium spending (adjusted percentage change, -26.3%; 95% CI, -41.0% to -8.1%; P = .01), and 39% lower odds of CHE (adjusted odds ratio, 0.61; 95% CI, 0.44 to 0.84; P = .002). Low-income patients experienced decreased out-of-pocket spending and out-of-pocket plus premium spending but no changes in CHE, while middle-income and high-income patients experienced no significant changes in any spending outcome. In the post-ACA period, 1 in 11 of all patients with traumatic injury and 1 in 5 with the lowest incomes continued to experience CHE each year.Implementation of the ACA was associated with improved financial protection for US adults with traumatic injury, especially lowest-income individuals targeted by the law's Medicaid expansions. Despite these gains, injured patients remain at risk of financial strain.

  • Variation in global uptake of the Surgical Safety Checklist. The British journal of surgery Delisle, M., Pradarelli, J. C., Panda, N., Koritsanszky, L., Sonnay, Y., Lipsitz, S., Pearse, R., Harrison, E. M., Biccard, B., Weiser, T. G., Haynes, A. B. 2020; 107 (2): e151-e160

    Abstract

    The Surgical Safety Checklist (SSC) is a patient safety tool shown to reduce mortality and to improve teamwork and adherence with perioperative safety practices. The results of the original pilot work were published 10 years ago. This study aimed to determine the contemporary prevalence and predictors of SSC use globally.Pooled data from the GlobalSurg and Surgical Outcomes studies were analysed to describe SSC use in 2014-2016. The primary exposure was the Human Development Index (HDI) of the reporting country, and the primary outcome was reported SSC use. A generalized estimating equation, clustering by facility, was used to determine differences in SSC use by patient, facility and national characteristics.A total of 85 957 patients from 1464 facilities in 94 countries were included. On average, facilities used the SSC in 75·4 per cent of operations. Compared with very high HDI, SSC use was less in low HDI countries (odds ratio (OR) 0·08, 95 per cent c.i. 0·05 to 0·12). The SSC was used less in urgent compared with elective operations in low HDI countries (OR 0·68, 0·53 to 0·86), but used equally for urgent and elective operations in very high HDI countries (OR 0·96, 0·87 to 1·06). SSC use was lower for obstetrics and gynaecology versus abdominal surgery (OR 0·91, 0·85 to 0·98) and where the common or official language was not one of the WHO official languages (OR 0·30, 0·23 to 0·39).Worldwide, SSC use is generally high, but significant variability exists. Implementation and dissemination strategies must be developed to address this variability.

    Abstract

    Background: As the number of patients surviving traumatic injuries has grown, understanding the factors that shape the recovery process has become increasingly important. However, the psychosocial factors affecting recovery from trauma have received limited attention. We conducted an exploratory qualitative study to better understand how patients view recovery after traumatic injury.Methods: This qualitative, descriptive study was conducted at a Level One university trauma center. Participants 1-3years postinjury were purposefully sampled to include common blunt-force mechanisms of injuries and a range of ages, socioeconomic backgrounds and injury severities. Semi-structured interviews explored participants' perceptions of self and the recovery process after traumatic injury. Interviews were transcribed verbatim; the data were inductively coded and thematically analyzed.Results: We conducted 15 interviews, 13 of which were with male participants (87%); average hospital length of stay was 8.9 days and mean injury severity score was 18.3. An essential aspect of the patient experience centered around the recovery of both the body and the 'self', a composite of one's roles, values, identities and beliefs. The process of regaining a sound sense of self was essential to achieving favorable subjective outcomes. Participants expressed varying levels of engagement in their recovery process, with those on the high end of the engagement spectrum tending to speak more positively about their outcomes. Participants described their own subjective interpretations of their recovery as most important, which was primarily influenced by their engagement in the recovery process and ability to recover their sense of self.Discussion: Patients who are able to maintain or regain a cohesive sense of self after injury and who are highly engaged in the recovery process have more positive assessments of their outcomes. Our findings offer a novel framework for healthcare providers and researchers to use as they approach the issue of recovery after injury with patients.Level of evidence: III-descriptive, exploratory study.

  • Survey of National Surgical Site Infection Surveillance Programs in Low- and Middle-Income Countries. Surgical infections Forrester, J. D., Berndtson, A. E., Santorelli, J. n., Raschke, E. n., Weiser, T. G., Coombs, A. V., Sawyer, R. G., Chou, J. n., Knight, H. P., Valenzuela, J. Y., Rickard, J. n. 2020

    Abstract

    Background: Surgical site infection (SSI) surveillance programs are strongly recommended as a core component of effective national infection prevention and control (IPC) programs. Participation in national SSI surveillance (nSSIS) programs has been shown to decrease reported SSIs among high-income countries (HICs), and it is expected that the same is possible among low- and middle-income countries (LMICs). We sought to determine what, if any nSSIS programs exist among LMICs. Methods: A cross-sectional survey was performed to evaluate existence of nSSIS of World Bank-defined LMICs. A digital survey assessment for presence of national IPC and nSSIS programs was delivered to persons capable of identifying the presence of such a program. Statistical analysis was performed using STATA. Institutional Review Board approval was obtained for this study. Results: Of the 137 countries identified, 55 (40%) were upper middle income (UMI), 47 (34%) were lower middle income (LMI), and 34 (25%) were low income. Representatives from 39 (28%) LMICs completed the survey. Of these respondent countries, 13 (33%) reported the presence of a national IPC program. There was no difference between countries with IPC programs and those without with respect to country income designation, population size, World Health Organization region, or conflict status. Only five (13% of all respondents) reported presence of a nSSIS program. Conclusions: National surgical site infection surveillance programs are an integral component of a country's ability to provide safe surgical procedures. Presence of nSSIS was reported infrequently in LMICs. International governing bodies should be encouraged to guide LMIC leadership in establishing a nSSIS infrastructure that will help enable safe surgical procedures.

  • Evidenced-Based Practice Among Trainees: A Survey on Facial Trauma Wound Management. Journal of surgical education Choi, J. n., Traboulsi, A. A., Okland, T. S., Sadauskas, V. n., Perrault, D. n., Spain, D. A., Lorenz, H. P., Weiser, T. G. 2020

    Abstract

    Assess whether facial trauma wound care and antibiotic use recommendations are guided by evidence-based practice (EBP) or practice patterns, and investigate strategies to improve EBP adoption among surgical trainees.We conducted a survey of all trainees who manage facial trauma (general surgery, emergency medicine, plastic surgery, otolaryngology) to assess clinical knowledge and sources of treatment recommendations. Clinical questions were based on Oxford Center for Evidence-Based Medicine Level 1 or 2 evidence. We measured internal validity of questions using Cronbach's α. Results were weight-adjusted for nonresponse and then analyzed using Welch t test and descriptive statistics.Stanford Hospital and Clinics, a Level I trauma center.Response rate was 50.3% overall (78/155). For recommendations on facial trauma wound and antibiotic use, nonspecialty junior residents most frequently relied on their own senior or specialty residents (79.1%); nonspecialty senior residents relied on specialty residents (67.9%). Specialty junior residents most often relied on their own senior residents (51.0%), the majority of whom made recommendations based on their own knowledge (73.2%). Questions assessing EBP knowledge had Cronbach's α of 0.98; response accuracy was similar between specialty and nonspecialty residents (54.6% vs 55.5%, p = 0.96). When provided recommendations that conflict with EBP, both nonspecialty and specialty residents more frequently followed recommendations rather than EBP; junior residents reported doing so to avoid conflict with superiors. Total 92.6% of surveyed residents felt cross-departmental EBP guidelines would improve patient care.Facial trauma wound care and antibiotic recommendations disseminate down seniority and from craniofacial specialty to nonspecialty residents, yet knowledge of EBP among senior specialty and nonspecialty residents was weak. EBP may be difficult to adopt in the absence of consensus society guidelines. To address this gap, we published a review of EBP for facial trauma and plan to update our trauma manual with cross-departmental guidelines to facilitate EBP adoption among trainees.

  • Safety of Foregoing Operation for Small Bowel Obstruction in the Virgin Abdomen: Systematic Review and Meta-Analysis. Journal of the American College of Surgeons Choi, J. n., Fisher, A. T., Mulaney, B. n., Anand, A. n., Carlos, G. n., Stave, C. D., Spain, D. A., Weiser, T. G. 2020

    Abstract

    Our objective was to assess the safety of foregoing surgery in patients without abdominopelvic surgery history presenting with small bowel obstruction (SBO). Classic dogma has counseled early surgical intervention for small bowel obstruction (SBO) in the virgin abdomen - patients without abdominopelvic surgery history - given their presumed higher risk of malignant or potentially catastrophic etiologies compared to those who underwent prior abdominal operations. The term virgin abdomen was coined before widespread use of computed tomography, which now elucidates many SBO etiologies. Despite recent efforts to re-evaluate clinical management standards, the prevalence of SBO etiologies in the virgin abdomen and the current management landscape (non-operative vs operative) in these patients remain unclear. Our random-effects meta-analysis of six studies including 442 patients found the prevalence of malignant etiologies in patients without abdominopelvic surgery history presenting with SBO varied from 7.7% [95% CI:3.0-14.1] to 13.4% [95% CI:7.6-20.3] on sensitivity analysis. Most malignant etiologies were not suspected prior to surgery. De novo adhesions (54%) were the most common etiology. Over half of patients underwent a trial of non-operative management, which often failed. Subgroups of patients likely have variable risk profiles for underlying malignant etiologies, yet no study had consistent follow-up data and we did not find convincing evidence that foregoing operative management altogether in this population can be generally recommended.

  • Surgical Infections in Low- and Middle-Income Countries: A Global Assessment of the Burden and Management Needs. Surgical infections Rickard, J., Beilman, G., Forrester, J., Sawyer, R., Stephen, A., Weiser, T. G., Valenzuela, J. 2019

    Abstract

    Background: The burden of surgical infections in low- and middle-income countries (LMICs) remains poorly defined compared with high-income countries. Although there are common infections necessitating surgery prevalent across the world, such as appendicitis and peptic ulcer disease, other conditions are more localized geographically. To date, comprehensive assessment of the burden of surgically treatable infections or sequelae of surgical infections in LMICs is lacking. Methods: We reviewed the literature to define the burden of surgical infections in LMICs and characterize the needs and challenges of addressing this issue. Results: Surgical infections comprise a broad range of diseases including intra-abdominal, skin and soft tissue, and healthcare-associated infections and other infectious processes. Treatment of surgical infections requires a functional surgical ecosystem, microbiology services, and appropriate and effective antimicrobial therapy. Systems must be developed and maintained to evaluate screening, prevention, and treatment strategies. Solutions and interventions are proposed focusing on reducing the burden of disease, improving surveillance, strengthening antibiotic stewardship, and enhancing the management of surgical infections. Conclusions: Surgical infections constitute a large burden of disease globally. Challenges to management in LMICs include a shortage of trained personnel and material resources. The increasing rate of antimicrobial drug resistance, likely related to antibiotic misuse, adds to the challenges. Development of surveillance, infection prevention, and antimicrobial stewardship programs are initial steps forward. Education is critical and should begin early in training, be an active process, and be sustained through regular programs.

    Abstract

    BACKGROUND: Clean Cut is a six month, multi-modal, adaptive intervention aimed at reducing surgical infections through improving six critical perioperative processes: 1) handwashing/skin preparation, 2) surgical gown/drape integrity, 3) antibiotic administration, 4) instrument sterility, 5) gauze counts, and 6) WHO Surgical Safety Checklist use. The aim of this study was to elucidate themes across Clean Cut implementation sites in Ethiopia to improve implementation at future hospitals.METHODS: We conducted semi-structured interviews of 20 clinicians involved in Clean Cut at four hospitals. Participation was limited to Clean Cut team members and included surgeons, anesthetists, operating room (OR) nurses, ward nurses, OR managers, quality improvement personnel, and hospital administrators. Audio recordings were transcribed and coded using qualitative software. A codebook was inductively and iteratively derived between two researchers, tested for inter-rater reliability, and applied to all transcripts. We conducted thematic analysis to derive our final qualitative results.RESULTS: The interviews revealed barriers and facilitators to the implementation of Clean Cut, as well as strategies for future implementation sites. Key barriers included material resource limitations, feelings of job burden, existing gaps in infection prevention education, and communication errors during data collection. Common facilitators included strong hospital leadership support, commitment to improved patient outcomes, and organized Clean Cut training sessions. Future strategies include resource assessments, creating a sense of responsibility among staff, targeted training sessions, and incorporating new standards into daily routine.CONCLUSIONS: The findings of this study highlight the importance of engaging hospital leadership, providers and staff in quality improvement programs, and understanding their work contexts. The identified barriers and facilitators will inform future initiatives in the field of perioperative infection prevention.

    Abstract

    Empirical, observational data relating to the diagnosis, management and outcome of three common worldwide cancers requiring surgery is lacking. However, it has been demonstrated that patients in low/middle-income countries undergoing surgery for cancer are at increased risk of death and major complications postoperatively. This study aims to determine quality and outcomes in breast, gastric and colorectal cancer surgery across worldwide hospital settings.This multicentre, international prospective cohort study will be undertaken by any hospital providing emergency or elective surgical services for breast, gastric or colorectal cancer. Centres will collect observational data on consecutive patients undergoing primary emergency or elective surgery for breast, gastric or colorectal cancer during a 6-month period. The primary outcome is the incidence of mortality and major complication rate at 30 days after cancer surgery. Infrastructure and care processes in the treatment of these cancers worldwide will also be characterised.This project will not affect clinical practice and has been classified as clinical audit following research ethics review. The protocol will be disseminated through the international GlobalSurg network.NCT03471494; Pre-results.

    Abstract

    BACKGROUND: Abdominal infections following surgery have many severe consequences. Several effective, well-evaluated infection prevention and control processes exist to avoid these infections.METHODS: This manuscript reviews and provides supporting evidence for common management strategies useful to avoid postoperative abdominal infection.RESULTS: Prevention of abdominal infection begins with preparation of the environment using standard infection control practices. Peri-operative use of systemic antibiotics, an antibiotic bowel preparation in colorectal surgery, and effective antiseptic preparation of the surgical site all reduce infection rates. Peri-operative supplemental oxygenation, maintenance of core body temperature, and physiologic euglycemia will reduce both incisional and organ-space infections in the abdominal surgery patient. Strategic use of irrigation and drain placement may be useful in some circumstances.CONCLUSION: Specific methods of prevention are documented to reduce intra-abdominal infections. Prevention requires a multi-disciplinary team including the surgeon, anesthesiologist, and all operating room personnel.

    Abstract

    The World Health Organization (WHO) Surgical Safety Checklist has fostered safe practice for 10 years, yet its place in emergency surgery has not been assessed on a global scale. The aim of this study was to evaluate reported checklist use in emergency settings and examine the relationship with perioperative mortality in patients who had emergency laparotomy.In two multinational cohort studies, adults undergoing emergency laparotomy were compared with those having elective gastrointestinal surgery. Relationships between reported checklist use and mortality were determined using multivariable logistic regression and bootstrapped simulation.Of 12 296 patients included from 76 countries, 4843 underwent emergency laparotomy. After adjusting for patient and disease factors, checklist use before emergency laparotomy was more common in countries with a high Human Development Index (HDI) (2455 of 2741, 89·6 per cent) compared with that in countries with a middle (753 of 1242, 60·6 per cent; odds ratio (OR) 0·17, 95 per cent c.i. 0·14 to 0·21, P < 0·001) or low (363 of 860, 42·2 per cent; OR 0·08, 0·07 to 0·10, P < 0·001) HDI. Checklist use was less common in elective surgery than for emergency laparotomy in high-HDI countries (risk difference -9·4 (95 per cent c.i. -11·9 to -6·9) per cent; P < 0·001), but the relationship was reversed in low-HDI countries (+12·1 (+7·0 to +17·3) per cent; P < 0·001). In multivariable models, checklist use was associated with a lower 30-day perioperative mortality (OR 0·60, 0·50 to 0·73; P < 0·001). The greatest absolute benefit was seen for emergency surgery in low- and middle-HDI countries.Checklist use in emergency laparotomy was associated with a significantly lower perioperative mortality rate. Checklist use in low-HDI countries was half that in high-HDI countries.

  • Implementation Challenges Using a Novel Method for Collecting Patient-Reported Outcomes After Injury. The Journal of surgical research Rosenberg, G. M., Shearer, E. J., Zion, S. R., Mackey, S. C., Morris, A. M., Spain, D. A., Weiser, T. G. 2019; 241: 277–84

    Abstract

    Monitoring longitudinal patient-reported outcomes after injury is important for comprehensive trauma care. Current methodologies are resource-intensive and struggle to engage patients.Patients ≥18 y old admitted to the trauma service were prospectively enrolled. The following inclusion criteria were used: emergency operation, ICU length of stay ≥2 midnights, or hospital length of stay ≥4 d. Validated and customized questionnaires were administered using a novel internet-based survey platform. Three-month follow-up surveys were administered. Contextual field notes regarding barriers to enrollment/completion of surveys and challenges faced by participants were recorded.Forty-seven patients were eligible; 26 of 47 (55%) enrolled and 19 of 26 (73%) completed initial surveys. The final sample included 14 (74%) men and 5 (26%) women. Primary barriers to enrollment included technological constraints and declined participation. Contextual field notes revealed three major issues: competing hospital tasks, problems with technology, and poor engagement. The average survey completion time was 43 ± 27 min-21% found this too long. Seventy-four percent reported the system "easy to use" and 95% reported they would "very likely" or "definitely" respond to future surveys. However, 10 of 26 (38%) patients completed 3-mo follow-up.Despite a well-rated internet-based survey platform, study participation remained challenging. Lack of email access and technological issues decreased enrollment and the busy hospitalization posed barriers to completion. Despite a thoughtful operational design and implementation plan, the trauma population presented a challenging group to engage. Next steps will focus on optimizing engagement, broadening access to survey reminders, and enhancing integration into clinical workflows.

  • Readmission risk and costs of firearm injuries in the United States, 2010-2015. PloS one Spitzer, S. A., Vail, D., Tennakoon, L., Rajasingh, C., Spain, D. A., Weiser, T. G. 2019; 14 (1): e0209896

    Abstract

    BACKGROUND: In 2015 there were 36,252 firearm-related deaths and 84,997 nonfatal injuries in the United States. The longitudinal burden of these injuries through readmissions is currently underestimated. We aimed to determine the 6-month readmission risk and hospital costs for patients injured by firearms.METHODS: We used the Nationwide Readmission Database 2010-2015 to assess the frequency of readmissions at 6 months, and hospital costs associated with readmissions for patients with firearm-related injuries. We produced nationally representative estimates of readmission risks and costs.RESULTS: Of patients discharged following a firearm injury, 15.6% were readmitted within 6 months. The average annual cost of inpatient hospitalizations for firearm injury was over $911 million, 9.5% of which was due to readmissions. Medicare and Medicaid covered 45.2% of total costs for the 5 years, and uninsured patients were responsible for 20.1%.CONCLUSIONS: From 2010-2015, the average total cost of hospitalization for firearm injuries per patient was $32,700, almost 10% of which was due to readmissions within 6 months. Government insurance programs and the uninsured shouldered most of this.

  • Cougar (Puma concolor) Injury in the United States. Wilderness & environmental medicine Wang, Y. Y., Weiser, T. G., Forrester, J. D. 2019

    Abstract

    Human encounters with the cougar (Puma concolor) are rare in the United States but may be fatal.We performed a retrospective analysis of cougar attacks in the United States. We asked Fish and Wildlife Department officials from the 16 states in which cougars are known to live to identify all verified cougar attacks recorded in state history. Variables describing the human victim, cougar, and conditions surrounding the attack were recorded. The Fisher exact test was used for comparison.Ten states reported 74 cougar attacks from 1924 to 2018. Persons less than 18 y of age were heavily represented among victims; 48% were <18 y old, and 35% were less than 10 y old. Attacks were more common in the summer and fall months. Most attacks occurred during daylight hours. The head, neck, and chest were the most common anatomic sites of injury. Sixteen (46%) victims were hospitalized after being attacked, among the 35 victims with these data available. Eleven (15%) attacks were fatal among 71 reports with this information. None of the hospitalized victims died (P=0.02). No victim variables were predictive of death.Cougar attacks are uncommon but can be fatal. Attacks commonly affect children and young adults, although all age groups are at risk of attack and death. Most attacks occur during the daytime in the summer and fall. As development and recreational activities put humans in closer contact with cougars, establishing validated public health messaging is critical to minimize injurious encounters.

  • Clinical update on management of pancreatic trauma HPB Soreide, K., Weiser, T. G., Parks, R. W. 2018; 20 (12): 1099–1108

    Abstract

    Pancreatic injury is rare and optimal diagnosis and management is still debated. The aim of this study was to review the existing data and consensus on management of pancreatic trauma.Systematic literature review until May 2018.Pancreas injury is reported in 0.2-0.3% of all trauma patients. Severity is scored by the organ injury scale (OIS), with new scores including physiology needing validation. Diagnosis is difficult, clinical signs subtle, and imaging by ultrasound (US) and computed tomography (CT) non-specific with <60% sensitivity for pancreatic duct injury. MRCP and ERCP have superior sensitivity (90-100%) for detecting ductal disruption. Early ERCP with stent is a feasible approach for initial management of all branch-duct and most main-duct injuries. Distal pancreatectomy (±splenectomy) may be required for a transected gland distal to the major vessels. Early peripancreatic fluid collections are common in ductal injuries and one-fifth may develop pseudocysts, of which two-thirds can be managed conservatively. Non-operative management has a high success rate (50-75%), even in high-grade injuries, but associated with morbidity. Mortality is related to associated injuries.Pancreatic injuries are rare and can often be managed non-operatively, supported by percutaneous drainage and ductal stenting. Distal pancreatectomy is the most common operative procedure.

    Abstract

    Introduction Patient care in the trauma-surgical intensive care unit (SICU) requires trust and effective communication between nurses and physicians. Our SICU suffered from poor communication and trust between nurses and physicians, negatively impacting the working environment and, potentially, patient care. Methods A SICU Task Force studied communication practices and identified areas for improvement, leading to several interventions. The daily physician rounding was altered to improve communication and to enhance the role of the registered nurses (RN) inrounds. Additionally, a formal night resident rounding time was implemented. Results A post-intervention survey focusing on cooperation, teamwork, and appreciation between nurses and physicians revealed improvement in these domains. Informal feedback from nurses and physicians indicated improved working relationships and satisfaction with the SICU environment. However, results of a national survey performed after the intervention did not show the same level of improvement. Conclusions A Task Force consisting of SICU nurses and physicians can effectively study a widespread communication issue and implement targeted interventions. While informal feedback may indicate improvement, it can be difficult to demonstrate improvement using formal surveys.

    Abstract

    Academic global surgery value to low- and middle-income countries (LMICs) is increasingly understood, yet value to academic health centers (AHCs) remains unclear.A task force from the Association for Academic Surgery Global Affairs Committee and the Society for University Surgeons Committee on Global Academic Surgery designed and disseminated a survey to active US academic global surgeons. Questions included participant characteristics, global surgeon qualifications, trainee interactions, academic output, productivity challenges, and career models. The task force used the survey results to create a position paper outlining the value of academic global surgeons to AHCs.The survey had a 58% (n = 36) response rate. An academic global surgeon has a US medical school appointment, spends dedicated time in an LMIC, spends vacation time doing mission work, or works primarily in an LMIC. Most spend 1 to 3 months abroad annually, dedicating <25% effort to global surgery, including systems building, teaching, research, and clinical care. Most are university-employed and 65% report compensation is equivalent or greater than colleagues. Academic support includes administrative, protected time, funding. Most institutions do not use specific global surgery metrics to measure productivity. Barriers include funding, clinical responsibilities, and salary support.Academic global surgeons spend a modest amount of time abroad, require minimal financial support, and represent a low-cost investment in an under-recognized scholarship area. This position paper suggests measures of global surgery that could provide opportunities for AHCs and surgical departments to expand missions of service, education, and research and enhance institutional reputation while achieving societal impact.

  • The association between angioembolization and splenic salvage for isolated splenic injuries. The Journal of surgical research Rosenberg, G. M., Weiser, T. G., Maggio, P. M., Browder, T. D., Tennakoon, L., Spain, D. A., Staudenmayer, K. L. 2018; 229: 150–55

    Abstract

    BACKGROUND: Recent data suggest improved splenic salvage rates when angioembolization (AE) is routinely employed for high-grade splenic injuries; however, protocols and salvage rates vary among centers.MATERIALS/METHODS: Adult patients with isolated splenic injuries were identified using the National Trauma Data Bank, 2013-2014. Patients were excluded if they underwent immediate splenectomy or died in the emergency department. To characterize patterns of AE, trauma centers were grouped into quartiles based on frequency of AE use. Unadjusted analyses and mixed-effects logistical regression controlling for center effects were performed.RESULTS: Five thousand and ninety three adult patients were identified. Overall, 705 (13.8%) underwent AE and 290 (5.7%) required a splenectomy. In unadjusted comparisons, splenectomy rates were lower for patients with severe spleen injuries who underwent AE (7% versus 11%, P=0.02). In mixed-effect logistical regression patients with severe splenic injuries undergoing AE had a lower odds ratio (OR) for splenectomy (OR = 0.67, P=0.04). Patients treated at centers in the highest quartile of AE use had a lower OR for splenectomy (OR = 0.58, P=0.02).CONCLUSIONS: The use of AE in patients with isolated severe splenic injuries is associated with decreased splenectomy rates. There is an association between centers that perform AE frequently and reduced splenectomy rates.

    Abstract

    BACKGROUND: Surgical infections are a major cause of morbidity and mortality in low- and middle-income countries (LMICs). Inadequately reprocessed surgical instruments can be a vector for pathogens. Little has been published on the current state of surgical instrument reprocessing in LMICs.METHODS: We performed a scoping review of English-language articles in PubMed, Web of Science, and Google Scholar databases describing current methods, policies, and barriers to surgical instrument reprocessing in LMICs. We conducted qualitative analysis of all studies to categorize existing practices and barriers to successful surgical instrument reprocessing. Barriers were non-exclusively categorized by theme: training/education, resource availability, environment, and policies/procedures. Studies associating surgical infections with existing practices were separately evaluated to assess this relationship.RESULTS: Nine hundred seventy-two abstracts were identified. Forty studies met criteria for qualitative analysis and three studies associated patient outcomes with surgical instrument reprocessing. Most studies (n=28, 70%) discussed institution-specific policies/procedures; half discussed shortcomings in staff training. Sterilization (n=38, 95%), verification of sterilization (n=19, 48%), and instrument cleaning and decontamination (n=16, 40%) were the most common instrument reprocessing practices examined. Poor resource availability and the lack of effective education/training and appropriate policies/procedures were cited as the common barriers. Of the case series investigating surgical instrument reprocessing with patient outcomes, improperly cleaned and sterilized neurosurgical instruments and contaminated rinse water were linked to Pseudomonas aeruginosa ventriculitis and Mycobacterium port site infections, respectively.CONCLUSIONS: Large gaps exist between instrument reprocessing practices in LMICs and recommended policies/procedures. Identified areas for improvement include instrument cleaning and decontamination, sterilization aspects of instrument reprocessing, and verification of sterilization. Education and training of staff responsible for reprocessing instruments and realistic, defined policies and procedures are critical, and lend themselves to improvement interventions.

    Abstract

    Surgical infections cause substantial morbidity and mortality in low-and middle-income countries (LMICs). To improve adherence to critical perioperative infection prevention standards, we developed Clean Cut, a checklist-based quality improvement program to improve compliance with best practices. We hypothesized that process mapping infection prevention activities can help clinicians identify strategies for improving surgical safety.We introduced Clean Cut at a tertiary hospital in Ethiopia. Infection prevention standards included skin antisepsis, ensuring a sterile field, instrument decontamination/sterilization, prophylactic antibiotic administration, routine swab/gauze counting, and use of a surgical safety checklist. Processes were mapped by a visiting surgical fellow and local operating theater staff to facilitate the development of contextually relevant solutions; processes were reassessed for improvements.Process mapping helped identify barriers to using alcohol-based hand solution due to skin irritation, inconsistent administration of prophylactic antibiotics due to variable delivery outside of the operating theater, inefficiencies in assuring sterility of surgical instruments through lack of confirmatory measures, and occurrences of retained surgical items through inappropriate guidelines, staffing, and training in proper routine gauze counting. Compliance with most processes improved significantly following organizational changes to align tasks with specific process goals.Enumerating the steps involved in surgical infection prevention using a process mapping technique helped identify opportunities for improving adherence and plotting contextually relevant solutions, resulting in superior compliance with antiseptic standards. Simplifying these process maps into an adaptable tool could be a powerful strategy for improving safe surgery delivery in LMICs.

    Abstract

    Areas of minimal access to surgical care, often called "surgical deserts", are of particular concern when considering the need for urgent surgical and anesthesia care. We hypothesized that California would have an appropriate workforce density but that physicians would be concentrated in urban areas, and surgical deserts would exist in rural counties.We used a benchmark of six general surgeons, six orthopedists, and eight anesthesiologists per 100,000 people per county to define a "desert". The number and location of these providers were obtained from the Medical Board of California for 2015. ArcGIS, version 10.3, was used to geocode the data and were analyzed in Redivis.There were a total of 3268 general surgeons, 3188 orthopedists, and 5995 anesthesiologists in California in 2015, yielding a state surgeon-to-population ratio of 7.2, 6.7, and 10.2 per 100,000 people, respectively; however, there was wide geographic variability. Of the 58 counties in California, 18 (31%) have a general surgery desert, 27 (47%) have an orthopedic desert, and 22 (38%) have an anesthesiology desert. These counties account for 15%, 25%, and 13% of the state population, respectively. Five, seven, and nine counties, respectively, have none in the corresponding specialty.Overall, California has an adequate ratio of surgical and anesthesia providers to population. However, because of their uneven distribution, significant surgical care deserts exist. Limited access to surgical and anesthesia providers may negatively impact patient outcome in these counties.

    Abstract

    Global surgery is an emerging academic discipline that is developing in tandem with numerous policy and advocacy initiatives. In this regard, academic global surgery will be crucial for measuring the progress toward improving surgical care worldwide. However, as a nascent academic discipline, there must be rigorous standards for the quality of work that emerges from this field. In this white paper, which reflects the opinion of the Global Academic Surgery Committee of the Society for University Surgeons, we discuss the importance of research in global surgery, the methodologies that can be used in such research, and the challenges and benefits associated with carrying out this research. In each of these topics, we draw on existing examples from the literature to demonstrate our points. We conclude with a call for continued, high-quality research that will strengthen the discipline's academic standing and help us move toward improved access to and quality of surgical care worldwide.

  • Trauma-induced insurance instability: Variation in insurance coverage for patients who experience readmission after injury. The journal of trauma and acute care surgery Rajasingh, C. M., Weiser, T. G., Knowlton, L. M., Tennakoon, L. n., Spain, D. A., Staudenmayer, K. L. 2018; 84 (6): 876–84

    Abstract

    Traumatic injuries result in a significant disruption to patients' lives, including their ability to work, which may place patients at risk of losing insurance coverage. Our objective was to evaluate the impact of injury on insurance status. We hypothesized that trauma patients with ongoing health needs experience changes in coverage.We used the Nationwide Readmission Database (2013-2014), a nationally representative sample of readmissions in the United States. We included patients aged 27 years to 64 years admitted with any diagnosis of trauma with at least one readmission within 6 months. Patients on Medicare and with missing payer information were excluded. The primary outcome was payer status.57,281 patients met inclusion criteria, 11,006 (19%) changed insurance payer at readmission. Of these, 21% (n = 2,288) became uninsured, 25% (n = 2,773) gained coverage, and 54% (n = 5,945) switched insurance. Medicaid and Medicare gained the largest fraction of patients (from 16% to 30% and 0% to 18%, respectively), with a decrease in private payer coverage (37% to 17%). In multivariate analysis, patients who were younger (27-35 years vs. 56-64 years; odds ratio [OR], 1.30; p < 0.001); lived in a zip code with average income in the lowest quartile (vs. the highest quartile; OR, 1.37; p < 0.001); and had three or more comorbidities (vs. none; OR, 1.61; p < 0.001) were more likely to experience a change in insurance.Approximately one fifth of trauma patients who are readmitted within 6 months of their injury experience a change in insurance coverage. Most switch between insurers, but nearly a quarter lose their insurance. The government adopts a large fraction of these patients, indicating a growing reliance on government programs like Medicaid. Trauma patients face challenges after injury, and a change in insurance may add to this burden. Future policy and quality improvement initiatives should consider addressing this challenge.Epidemiologic, level III.

    Abstract

    More people are surviving traumatic injury, but disability and reduced quality of life are frequent. Investigators are now focusing on patient-reported outcomes (PROs) to better understand this problem. We performed a scoping study of the literature to explore trends in the study of PROs after injury. The volume of published literature on PROs after injury has consistently increased, but use of measurement tool and categorization of publications are inconsistent. Journal keyword patterns are inconsistent and likely limit the effective dissemination of important findings. In studies of hospitalized trauma patients, more than 100 unique measurement tools were used, and trauma-specific measures were used in fewer than 5% of studies. International investigators are more consistent than those in the USAin the use of validated, classic measurement tools such as the Short-Form 36 and the EuroQoL Five-Dimension tools. Uniform use of measurement tools would help improve the quality and comparability of research on PROs, and trauma-specific measures would enhance the study of long-term injury outcomes.

    Abstract

    Surgical site infections (SSIs) are a leading cause of post-operative morbidity and mortality. We developed Clean Cut, a surgical infection prevention program, with two goals: (1) Increase adherence to evidence-based peri-operative infection prevention standards and (2) establish sustainable surgical infection surveillance. Here we describe our infection surveillance strategy.Clean Cut was piloted and evaluated at a 523 bed tertiary hospital in Ethiopia. Infection prevention standards included: (1) Hand and surgical site decontamination; (2) integrity of gowns, drapes, and gloves; (3) instrument sterility; (4) prophylactic antibiotic administration; (5) surgical gauze tracking; and (6) checklist compliance. Primary outcome measure was SSI, with secondary outcomes including other infection, re-operation, and length of stay. We prospectively observed all post-surgical wounds in obstetrics over a 12 day period and separately recorded post-operative complications using chart review. Simultaneously, we reviewed the written hospital charts after patient discharge for all patients whose peri-operative adherence to infection prevention standards was captured.Fifty obstetric patients were followed prospectively with recorded rates of SSI 14%, re-operation 6%, and death 2%. Compared with direct observation, chart review alone had a high loss to follow-up (28%) and decreased capture of infectious complications (SSI [n = 2], endometritis [n = 3], re-operations [n = 2], death [n = 1]); further, documentation inconsistencies failed to capture two complications (SSI [n = 1], mastitis [n = 1]). Concurrently, 137 patients were observed for peri-operative infection prevention standard adherence. Of these, we were able to successfully review 95 (69%) patient charts with recorded rates of SSI 5%, re-operation 1%, and death 1%.Patient loss to follow-up and poor documentation of infections underestimated overall infectious complications. Direct, prospective follow-up is possible but requires increased time, clinical skill, and training. For accurate surgical infection surveillance, direct follow-up of patients during hospitalization is essential, because chart review does not accurately reflect post-operative complications.

    Abstract

    Musculoskeletal trauma represents a large source of morbidity in low and middle human development index countries (LMHDICs). Open reduction and internal fixation (ORIF) of traumatic long bone fractures definitively manages these injuries and restores function when conducted safely and effectively. Surgical site infections (SSIs) are a common complication of operative fracture fixation, although the risks of infection are ill-defined in LMHDIC.This study reviewed systematically all studies describing SSI after ORIF in LMDHICs. Studies were reviewed based on their qualitative characteristics, after which a quantitative synthesis of weighted pooled infection rates based on available patient-level data was performed to estimate published incidence of SSI.Forty-two studies met criteria for qualitative review and 32 studies comprising 3,084 operations were included in the quantitative analysis. Among 3,084 operations, the weighted pooled SSI rate was 6.4 infections per 100 procedures (95% confidence interval [CI] 4.6-8.2 infections per 100 procedures). Higher rates of infection were noted among the sub-group of open fractures (95% CI 13.9-23.0 infections per 100 procedures). Lower extremity injuries and procedures utilizing intra-medullary nails also had slightly higher rates of infection versus upper extremity procedures and other fixation devices.Reported rates of SSI after ORIF are higher in LMHDICs, and may be driven by high rates of infection in the sub-group of open fractures. This study provides a baseline SSI rate obtained from literature produced from LMHDICs. Infection rates are highly dependent on fracture sub-types.

  • An Update on Fatalities Due to Venomous and Nonvenomous Animals in the United States (2008-2015). Wilderness & environmental medicine Forrester, J. A., Weiser, T. G., Forrester, J. D. 2018

    Abstract

    To review recent (2008-2015) United States mortality data from deaths caused by nonvenomous and venomous animals and compare with historical data.The Centers for Disease Control and Prevention Wide-Ranging Online Data for Epidemiologic Research database was queried to return all animal-related fatalities between 2008 and 2015. Mortality frequencies for animal-related fatalities were calculated using the estimated 2011 United States population. Inclusion criteria included all mortalities that were a consequence of bite, contact, attack, or envenomation (International Classification of Diseases 10th revision codes W53-W59 and X20-X29).There were 1610 animal-related fatalities, with the majority from nonvenomous animals (2.8 deaths per 10 million persons). The largest proportion of animal-related fatalities was due to "other mammals," largely composed of horses and cattle. Deaths attributable to Hymenoptera (hornets, wasps, and bees) account for 29.7% of the overall animal-related fatalities and have been steady over the last 20 years. Dog-related fatality frequencies are stable, although the fatality frequency of 4.6 deaths per 10 million persons among children 4 years of age or younger was nearly 4-fold greater than in the other age groups.Appropriate education and prevention measures aimed at decreasing injury from animals should be directed at the high-risk groups of agricultural workers and young children with dogs. Public policy and treatment pricing should align to ensure adequate available medication for those at risk of anaphylaxis from stings from Hymenoptera.

  • Why do patients receive care from a short-term medicalmission? Survey study from rural Guatemala JOURNAL OF SURGICAL RESEARCH Esquivel, M. M., Chen, J. C., Woo, R. K., Siegler, N., Maldonado-Sifuentes, F. A., Carlos-Ochoa, J. S., Cardona-Diaz, A. R., Uribe-Leitz, T., Siegler, D., Weiser, T. G., Yang, G. P. 2017; 215: 160–66

    Abstract

    Hospital de la Familia was established to serve the indigent population in the western highlands of Guatemala and has a full-time staff of Guatemalan primary care providers supplemented by short-term missions of surgical specialists. The reasons for patients seeking surgical care in this setting, as opposed to more consistent care from local institutions, are unclear. We sought to better understand motivations of patients seeking mission-based surgical care.Patients presenting to the obstetric and gynecologic, plastic, ophthalmologic, general, and pediatric surgical clinics at the Hospital de la Familia from July 27 to August 6, 2015 were surveyed. The surveys assessed patient demographics, surgical diagnosis, location of home, mode of travel, and reasons for seeking care at this facility.Of 252 patients surveyed, 144 (59.3%) were female. Most patients reported no other medical condition (67.9%, n = 169) and no consistent income (83.9%, n = 209). Almost half (44.9%, n = 109) traveled >50 km to receive care. The most common reasons for choosing care at this facility were reputation of high quality (51.8%, n = 130) and affordability (42.6%, n = 102); the least common reason was a lack of other options (6.4%, n = 16).Despite long travel distances and the availability of other options, reputation and affordability were primarily cited as the most common reasons for choosing to receive care at this short-term surgical mission site. Our results highlight that although other surgical options may be closer and more readily available, reputation and cost play a large role in choice of patients seeking care.

  • Clinical phenotypes of US level I trauma centers: use of clustering methodology Forrester, J. D., Weiser, T. G., Maggio, P., Browder, T., Tennakoon, L., Spain, D. A., Staudenmayer, K. ACADEMIC PRESS INC ELSEVIER SCIENCE. 2017: 146–52

    Abstract

    American College of Surgeons Level I Trauma Centers (ACSL1TCs) meet the same personnel and structural requirements but serve different populations. We hypothesized that these nuanced differences may amenable to description through mathematical clustering methodology.The National Trauma Data Bank 2014 was used to derive information on ACSL1TCs. Explorative cluster hypothesis generation was performed using Ward's linkage to determine expected number of clusters based on patient and injury characteristics. Subsequent k-means clustering was applied for analysis. Comparison between clusters was performed using the Kruskal-Wallis or chi-square test.In 2014, 113 ACSL1TCs admitted 267,808 patients (median = 2220 patients, range: 928-6643 patients). Three clusters emerged. Cluster I centers (n = 53, 47%) were more likely to admit older, Caucasian patients who suffered from falls (P < 0.05) and had higher proportions of private (31%) and Medicare payers (29%) (P = 0.001). Cluster II centers (n = 18, 16%) were more likely to admit younger, minority males who suffered from penetrating trauma (P < 0.05) and had higher proportions of Medicaid (24%) or self-pay patients (19%) (P = 0.001). Cluster III centers (n = 42, 37%) were similar to cluster I with respect to racial demographic and payer status but resembled cluster II centers with respect to injury patterns (P < 0.05).Our analysis identified three unique, mathematically definable clusters of ACSL1TCs serving three broadly different patient populations. Understanding these mathematically definable clusters should have utility when assessing an institution's financial risk profile, directing prevention and outreach programs, and performing needs and resource assessments. Ultimately, clustering allows for more meaningful direct comparisons between phenotypically similar trauma centers.

A., Weiser, T. G. 2017; 95 (6): 437–44

    Abstract

    To assess the consistent availability of basic surgical resources at selected facilities in seven countries.In 2010-2014, we used a situational analysis tool to collect data at district and regional hospitals in Bangladesh (n = 14), the Plurinational State of Bolivia (n = 18), Ethiopia (n = 19), Guatemala (n = 20), the Lao People's Democratic Republic (n = 12), Liberia (n = 12) and Rwanda (n = 25). Hospital sites were selected by pragmatic sampling. Data were geocoded and then analysed using an online data visualization platform. Each hospital's catchment population was defined as the people who could reach the hospital via a vehicle trip of no more than two hours. A hospital was only considered to show consistent availability of basic surgical resources if clean water, electricity, essential medications including intravenous fluids and at least one anaesthetic, analgesic and antibiotic, a functional pulse oximeter, a functional sterilizer, oxygen and providers accredited to perform surgery and anaesthesia were always available.Only 41 (34.2%) of the 120 study hospitals met the criteria for the provision of consistent basic surgical services. The combined catchments of the study hospitals in each study country varied between 3.3 million people in Liberia and 151.3 million people in Bangladesh. However, the combined catchments of the study hospitals in each study country that met the criteria for the provision of consistent basic surgical services were substantially smaller and varied between 1.3 million in Liberia and 79.2 million in Bangladesh.Many study facilities were deficient in the basic infrastructure necessary for providing basic surgical care on a consistent basis.

  • The prevalence of psychiatric diagnoses and associated mortality in hospitalized US trauma patients JOURNAL OF SURGICAL RESEARCH Townsend, L. L., Esquivel, M. M., Uribe-Leitz, T., Weiser, T. G., Maggio, P. M., Spain, D. A., Tennakoon, L., Staudenmayer, K. 2017; 213: 171–76

    Abstract

    We hypothesized that psychiatric diagnoses would be common in hospitalized trauma patients in the United States and when present, would be associated with worse outcomes.The Nationwide Inpatient Sample (NIS, 2012) was used to determine national estimates for the number of patients admitted with an injury. Psychiatric diagnoses were identified using diagnosis codes according to the Diagnostic and Statistical Manual of Mental Disorders, Fifth Edition.A total of 36.5 million patients were admitted to hospitals in the United States in 2012. Of these, 1.3 million (4%) were due to trauma. Psychiatric conditions were more common in patients admitted for trauma versus those admitted for other reasons (44% versus 34%, P < 0.001). Trauma patients who had a psychiatric diagnosis compared to trauma patients without a psychiatric diagnosis were older (mean age: 61 versus 56 y, P < 0.001), more often female (52% versus 50%, P < 0.001), and more often white (73% versus 68%, P < 0.001). For ages 18-64, drug and alcohol abuse predominated (41%), whereas dementia and related disorders (48%) were the most common in adults ≥65 y. Mortality was lower for trauma patients with a psychiatric diagnosis compared to those who did not in both unadjusted and adjusted analysis (1.9% versus 2.8%; odds ratio: 0.56, P < 0.001).Psychiatric conditions are present in almost half of all hospitalized trauma patients in the United States; however, the types of conditions varied with age. The frequency of psychiatric conditions in the trauma population suggests efforts should be made to address this component of patient health.

  • Costs and Financial Burden of Initial Hospitalizations for Firearm Injuries in the United States, 2006-2014. American journal of public health Spitzer, S. A., Staudenmayer, K. L., Tennakoon, L., Spain, D. A., Weiser, T. G. 2017; 107 (5): 770-774

    Abstract

    To quantify the inflation-adjusted costs associated with initial hospitalizations for firearm-related injuries in the United States.We used the Healthcare Cost and Utilization Project Nationwide Inpatient Sample to identify patients admitted for firearm-related injuries from 2006 to 2014. We converted charges from hospitalization to costs, which we inflation-adjusted to 2014 dollars. We used survey weights to create national estimates.Costs for the initial inpatient hospitalization totaled $6.61 billion. The largest proportion was for patients with governmental insurance coverage, totaling $2.70 billion (40.8%) and was divided between Medicaid ($2.30 billion) and Medicare ($0.40 billion). Self-pay individuals accounted for $1.56 billion (23.6%) in costs.From 2006 to 2014, the cost of initial hospitalizations for firearm-related injuries averaged $734.6 million per year. Medicaid paid one third and self-pay patients one quarter of the financial burden. These figures substantially underestimate true health care costs. Public health implications. Firearm-related injuries are costly to the US health care system and are particularly burdensome to government insurance and the self-paying poor.

  • Population-based estimate of trauma-related deaths for law enforcement personnel: Risks for death are higher and increasing over time. journal of trauma and acute care surgery Eastman, A. L., Cripps, M. W., AbdelFattah, K. R., Inaba, K., Weiser, T. G., Spain, D. A., Staudenmayer, K. L. 2017

    Abstract

    Trauma-related deaths remain an important public health problem. One group susceptible to death due to traumatic mechanisms is U.S. Law Enforcement (LE). We hypothesized that LE officers experienced a higher chance of violent death compared to the general U.S. population and that risks have increased over time.The National Institute on Occupational Safety and Health (NIOSH) National Occupational Mortality Surveillance (NOMS) is a population-based survey of occupational deaths. It includes data for workers who died during 1985-1998 in one of 30 U.S states (EARLY period). Additional deaths were added from 23 U.S. states in 1999, 2003-2004, 2007-2010 (LATE period). Mortality rates are estimated by calculating proportionate mortality ratios (PMR). A PMR above 100 is considered to exceed the average background risk for all occupations. All adults >18 years of age whose primary occupation was listed as "Law Enforcement Worker" were included in the analysis.Law enforcement personnel were more likely to die from an injury compared to the general population (Figure 1). The overall PMR for injury in EARLY was 111 (95% Confidence Interval [CI] 108-114, p<0.01), and for LATE was 118 (95% CI 110-127, p<0.01). Four mechanisms of death reached statistical significance: motor vehicle traffic (MVT)-driver, MVT-other, intentional self-harm, and assault/homicide. The highest PMR in EARLY was associated with firearms (PMR 272, 95% CI 207-350, p<0.01). The highest PMR in LATE was associated with death due to being a driver in an MVT (PMR 194, 95% CI 169-222, p<0.01). There were differences in risk of death by race and gender. White females had the highest PMR due to Assault and Homicide (PMR 317, 95% CI 164-554, p<0.01). All groups had similar risks of death due to Intentional Self-Harm (PMR 130-171).The risk of death for US LEOs is high and increasing over time, suggesting an at-risk population that requires further interventions. Targeted efforts based on risk factors, such as gender and race, may assist with the development of prevention programs for this population.

  • Surgical Site Infections after Tissue Flaps Performed in Low and Middle Human Development Index Countries: A Systematic Review. Surgical infections Cai, L. Z., Chang, J. n., Weiser, T. G., Forrester, J. D. 2017

    Abstract

    Surgical site infections (SSIs) affect the safety of surgical care and are particularly problematic and prevalent in low and middle Human Development Index Countries (LMHDICs).We performed a systematic review of the existing literature on SSIs after tissue flap procedures in LMHDICs through the PubMed, Ovid, and Web of Science databases. Of the 405 abstracts identified, 79 were selected for full text review, and 30 studies met inclusion criteria for analysis.In the pooled analysis, the SSI rate was 5.8 infections per 100 flap procedures (95% confidence interval [CI] 2%-10%, range: 0-40%). The most common indication for tissue flap was pilonidal sinus repair, which had a pooled SSI rate of 5.6 infections per 100 flap procedures (95% CI 2%-10%, range: 0-15%). No fatalities from an infection were noted. The reporting of infection epidemiology, prevention, and treatment was poor, with few studies reporting antibiotic agent use (37%), responsible pathogens (13%), infection comorbidities (13%), or time to infection (7%); none reported cost.Our review highlights the need for more work to develop standardized hospital-based reporting for surgical outcomes and complications, as well as future studies by large, multi-national groups to establish baseline incidence rates for SSIs and best practice guidelines to monitor SSI rates.

  • Impact of Surgical Lighting on Intraoperative Safety in Low-Resource Settings: A Cross-Sectional Survey of Surgical Providers. World journal of surgery Forrester, J. A., Boyd, N. J., Fitzgerald, J. E., Wilson, I. H., Bekele, A. n., Weiser, T. G. 2017

    Abstract

    Safe surgery requires high-quality, reliable lighting of the surgical field. Little is reported on the quality or potential safety impact of surgical lighting in low-resource settings, where power failures are common and equipment and resources are limited.Members of the Lifebox Foundation created a novel, non-mandatory, 18-item survey tool using an iterative process. This was distributed to surgical providers practicing in low-resource settings through surgical societies and mailing lists.We received 100 complete responses, representing a range of surgical centres from 39 countries. Poor-quality surgical field lighting was reported by 40% of respondents, with 32% reporting delayed or cancelled operations due to poor lighting and 48% reporting electrical power failures at least once per week. Eighty per cent reported the quality of their surgical lighting presents a patient safety risk with 18% having direct experience of poor-quality lighting leading to negative patient outcomes. When power outages occur, 58% of surgeons rely on a backup generator and 29% operate by mobile phone light. Only 9% of respondents regularly use a surgical headlight, with the most common barriers reported as unaffordability and poor in-country suppliers.In our survey of surgeons working in low-resource settings, a majority report poor surgical lighting as a major risk to patient safety and nearly one-third report delayed or cancelled operations due to poor lighting. Developing and distributing robust, affordable, high-quality surgical headlights could provide an ideal solution to this significant surgical safety issue.

  • Using the WHO Surgical Safety Checklist to Direct Perioperative Quality Improvement at a Surgical Hospital in Cambodia: The Importance of Objective Confirmation of Process Completion. World journal of surgery Garland, N. Y., Kheng, S. n., De Leon, M. n., Eap, H. n., Forrester, J. A., Hay, J. n., Oum, P. n., Sam Ath, S. n., Stock, S. n., Yem, S. n., Lucas, G. n., Weiser, T. G. 2017

    Abstract

    The WHO surgical safety checklist (SSC) is known to prevent postoperative complications; however, strategies for effective implementation are unclear. In addition to cultural and organizational barriers faced by high-income countries, resource-constrained settings face scarcity of durable and consumable goods. We used the SSC to better understand barriers to improvement at a trauma hospital in Battambang, Cambodia.We introduced the SSC and trained data collectors to observe surgical staff performing the checklist. Members of the research team observed cases and data collection. After 3 months, we modified the data collection tool to focus on infection prevention and elicit more accurate responses.Over 16 months we recorded data on 695 operations (304 cases using the first tool and 391 cases with the modified tool). The first tool identified five items as being in high compliance, which were then excluded from further assessment. Two items-instrument sterility confirmation and sponge counting-were identified as being misinterpreted by the data collectors' tool. These items were reworded to capture objective assessment of task completion. Confirmation of instrument sterility was initially never performed but rectified to >95% compliance; sponge counting and prophylactic antibiotic administration were consistently underperformed.Staff complied with communication elements of the SSC and quickly adopted process improvements. The wording of our data collection tool affected interpretation of compliance with standards. Material resources are not the primary barrier to checklist implementation in this setting, and future work should focus on clarification of protocols and objective confirmation of tasks.

  • Surgical Site Infections after Appendectomy Performed in Low and Middle Human Development-Index Countries: A Systematic Review. Surgical infections Foster, D. n., Kethman, W. n., Cai, L. Z., Weiser, T. G., Forrester, J. D. 2017

    Abstract

    Acute appendicitis is a common surgical emergency worldwide. Early intervention is associated with better outcomes. In low and middle Human Development-Index Countries (LMHDICs), late presentation and poor access to healthcare facilities can contribute to greater illness severity and higher complication rates, such as post-operative surgical site infections (SSIs). The current rate of SSIs post-appendectomy in low- and middle-index settings has yet to be described.We performed a systemic review of the literature describing the incidence and management of SSIs after appendectomy in LMHDICs. We conducted qualitative and quantitative analysis of the data in manuscripts describing patients undergoing appendectomy to establish a baseline SSI rate for this procedure in these settings.Four hundred twenty-three abstracts were initially identified. Of these, 35 studies met the criteria for qualitative and quantitative analysis. The overall weighted, pooled SSI rated were 17.9 infections/100 open appendectomies (95% confidence interval [CI] 10.4-25.3 infections/100 open appendectomies) and 8.8 infections/100 laparoscopic appendectomies (95% CI 4.5-13.2 infections/100 laparoscopic appendectomies). The SSI rates were higher in complicated appendicitis and when pre-operative antibiotic use was not specified.Observed SSI rates after appendectomy in LMHDICs are dramatically higher than rates in high Human Development-Index Countries. This is particularly true in cases of open appendectomy, which remains the most common surgical approach in LMHDICs. These findings highlight the need for SSI prevention in LMHDICs, including prompt access to medical and surgical care, routine pre-operative antibiotic use, and implementation of bundled care packages and checklists.

  • Surgical Site Infections after Inguinal Hernia Repairs Performed in Low and Middle Human Development Index Countries: A Systematic Review. Surgical infections Cai, L. Z., Foster, D. n., Kethman, W. C., Weiser, T. G., Forrester, J. D. 2017

    Abstract

    Inguinal hernias are a common disorder in low- and middle-human development index countries (LMHDICs). Poor access to surgical care and lack of patient awareness often lead to delayed presentations of incarcerated or strangulated hernias and their associated morbidities. There is a scarcity of data on the baseline incidence of surgical site infections (SSIs) after hernia repair procedures in LMHDICs.We performed a systematic review of the literature describing the incidence and management of SSIs after inguinal hernia repair in LMHDICs. We conducted qualitative and quantitative analyses of manuscripts describing patients undergoing hernia repair to establish a baseline SSI rate for this procedure in these settings.Three hundred twenty-three abstracts were identified after applying search criteria, and 31 were suitable for the quantitative analysis. The overall pooled SSI rate was 4.1 infections/100 open hernia repairs (95% confidence interval [CI] 3.0-5.3 infections/100 open repairs), which is consistent with infection rates from high-human development index countries. A separate subgroup analysis of laparoscopic hernia repairs found a weighted pooled SSI rate of 0.4 infections/100 laparoscopic repairs (95% CI 0-2.4 infections/100 laparoscopic repairs).As surgical access continues to expand in LMHDIC settings, it is imperative to monitor surgical outcomes and ensure that care is provided safely. Establishing a baseline SSI rate for inguinal hernia repairs offers a useful benchmark for future studies and surgical programs in these countries.

  • Surgical Site Infection after Sternotomy in Low- and Middle-Human Development Index Countries: A Systematic Review. Surgical infections Forrester, J. D., Cai, L. Z., Zeigler, S. n., Weiser, T. G. 2017; 18 (7): 774–79

    Abstract

    The burden of cardiovascular disease is increasing in low- and middle-human development index (LMHDI) countries, and cardiac operations are an important component of a comprehensive cardiovascular care package. Little is known about the baseline incidence of surgical site infections (SSIs) among patients undergoing sternotomy in LMHDI countries.A prospectively registered, systematic literature review of articles in the PubMed, Ovid, and Web of Science databases describing the epidemiology and management of SSIs among persons undergoing sternotomy in LMHDI countries was performed. We performed a quantitative synthesis of patients undergoing sternotomy for CABG to estimate published sternotomy SSI rates.Of the 423 abstracts identified after applying search criteria, 14 studies were reviewed in detail. The pooled SSI rate after sternotomy among reviewed studies was 4.3 infections per 100 sternotomies (95% confidence interval [CI] 1.3-6.0 infections per 100 sternotomies), which is comparable to infection rates in high-human development index countries.As the burden of cardiovascular disease in LMHDI settings increases, the ability to provide safe cardiac surgical care is paramount. Describing the baseline SSI rate after sternotomy in LMHDI countries is an important first step in creating baseline expectations for SSI rates in cardiac surgical programs in these settings.

    Abstract

    Surgical care is widely unavailable in developing countries; advocates recommend that countries evaluate and report on access to surgical care to improve availability and aid health planners in decision making.To analyze the infrastructure, capacity, and availability of surgical care in Zambia to inform health policy priorities.In this observational study, all hospitals providing surgical care were identified in cooperation with the Zambian Ministry of Health. On-site data collection was conducted from February 1 through August 30, 2011, with an adapted World Health Organization Global Initiative for Emergency and Essential Surgical Care survey. Data collection at each facility included interviews with hospital personnel and assessment of material resources. Data were geocoded and analyzed in a data visualization platform from March 1 to December 1, 2015. We analyzed time and distance to surgical services, as well as the proportion of the population living within 2 hours from a facility providing surgical care.Surgical capacity, supplies, human resources, and infrastructure at each surgical facility, as well as the population living within 2 hours from a hospital providing surgical care.Data were collected from all 103 surgical facilities identified as providing surgical care. When including all surgical facilities (regardless of human resources and supplies), 14.9% of the population (2 166 460 of 14 500 000 people) lived more than 2 hours from surgical care. However, only 17 hospitals (16.5%) met the World Health Organization minimum standards of surgical safety; when limiting the analysis to these hospitals, 65.9% of the population (9 552 780 people) lived in an area that was more than 2 hours from a surgical facility. Geographic analysis of emergency and essential surgical care, defined as access to trauma care, obstetric care, and care of common abdominal emergencies, found that 80.7% of the population (11 704 700 people) lived in an area that was more than 2 hours from these surgical facilities.A large proportion of the population in Zambia does not have access to safe and timely surgical care; this percentage would change substantially if all surgical hospitals were adequately resourced. Geospatial visualization tools assist in the evaluation of surgical infrastructure in Zambia and can identify key areas for improvement.

    Abstract

    Coccidioidomycosis, commonly called "valley fever," "San Joaquin fever," "desert fever," or "desert rheumatism," is a multi-system illness caused by infection with Coccidioides fungi (C. immitis or C. posadasii). This organism is endemic to the desert Southwest regions of the United States and Mexico and to parts of South America. The manifestations of infection occur along a spectrum from asymptomatic to mild self-limited fever to severe disseminated disease.Review of the English-language literature.There are five broad indications for surgical intervention in patients with coccidioidomycosis: Tissue diagnosis in patients at risk for co-existing pathology, perforation, bleeding, impingement on critical organs, and failure to resolve with medical management. As part of a multidisciplinary team, surgeons may be responsible for the care of infected patients, particularly those with severe disease.This review discusses the history, microbiology, epidemiology, pathology, diagnosis, and treatment of coccidioidomycosis, focusing on situations that may be encountered by surgeons.

    Abstract

    Trauma patients with vascular injuries have historically been within a general surgeon's operative ability. Changes in training and decline in operative trauma have decreased trainees' exposure to these injuries. We sought to determine how frequently vascular procedures are performed at US trauma centers to quantify the need for general surgeons trained to manage vascular injuries.We conducted a retrospective analysis of the National Trauma Data Base (NTDB) from 2012 compared with 2002. Patients with general surgical and vascular procedures were identified using International Classification of Diseases, Ninth Revision, procedure codes 38.0-39.99, excluding 38.9-38.99.General surgery or vascular operations were performed on 12,099 (24%) of 50,248 severely injured adult patients in 2002 and 21,854 (16%) of 138,009 injured patients in 2012. Nineteen percent to 26% of all patients underwent vascular procedures. Patients with combined general surgery and vascular procedures were less likely to be discharged home and more likely to die. In 2002, 6% of severely injured adult trauma patients underwent open vascular procedures at level III/IV trauma centers; by 2012, only 1% of vascular surgery procedures were performed at level III/IV centers (P < 0.001).Need for emergent vascular surgery remains common for severely injured patients. Future trauma systems and surgical training programs will need to account for the need for open vascular skills. The findings suggest that there is already a trend away from open vascular procedures at level III/IV trauma centers, which may be a sign of system compensation for changes in the workforce.

  • Trends in the management of pelvic fractures, 2008-2010 JOURNAL OF SURGICAL RESEARCH Chu, C. H., Tennakoon, L., Maggio, P. M., Weiser, T. G., Spain, D. A., Staudenmayer, K. L. 2016; 202 (2): 335-340

    Abstract

    Bleeding from pelvic fractures can be lethal. Angioembolization (AE) and external fixation (EXFIX) are common treatments to control bleeding, but it is not known how frequently they are used. We hypothesized that AE would be increasingly more common compared with EXFIX over time.The National Trauma Data Bank for the years from 2008-2010 were used. Patients were included in the study if they had an International Classification of Diseases, ninth edition, Clinical Modification codes for pelvic fractures and were aged ≥18 y. Patients were excluded if they had isolated acetabular fractures, were not admitted, or had minor injuries. Outcomes included receiving a procedure and in-hospital mortality.A total of 22,568 patients met study criteria. AE and EXFIX were performed in 746 (3.3%) and 663 (2.9%) patients, respectively. AE was performed more often as the study period progressed (2.5% in 2007 to 3.7% in 2010; P < 0.001). This remained significant in adjusted analysis (odds ratio per year 1.15; P = 0.008). Having a procedure was associated with higher mortality in unadjusted analyses compared with those with no procedure (11.0% for no procedure versus 20.5% and 13.4% for AE or EXFIX, respectively; P < 0.001). In adjusted analyses, only AE remained associated with higher mortality (odds ratio 1.63; P < 0.001).AE in severely injured pelvic fracture patients is increasing. AE is associated with higher mortality, which may reflect the fact that it is used for patients at higher risk of death. The role of AE for bleeding should be examined in future studies.

  • The Triage of Injured Patients: Mechanism of Injury, Regardless of Injury Severity, Determines Hospital Destination AMERICAN SURGEON Staudenmayer, K., Wang, N. E., Weiser, T. G., Maggio, P., Mackersie, R. C., Spain, D., Hsia, R. Y. 2016; 82 (4): 356-361

    Abstract

    The target rate for trauma undertriage is <5 per cent, but rates are as high as 30 to 40 per cent in many trauma systems. We hypothesized that high undertriage rates were due to the tendency to undertriage injured elderly patients and a growing elderly population. We conducted a retrospective analysis of all hospital visits in California using the Office of Statewide Health Planning and Development Database over a 5-year period. All hospital admissions and emergency department visits associated with injury were longitudinally linked. The primary outcome was triage pattern. Triage patterns were stratified across three dimensions: age, mechanism of injury, and access to care. A total of 60,182 severely injured patients were included in the analysis. Fall-related injuries were frequently undertriaged compared with injuries from motor vehicle collisions (MVCs) and penetrating trauma (52% vs 12% and 10%, respectively). This pattern was true for all age groups. Conversely, MVCs and penetrating traumas were associated with high rates of overtriage (>70% for both). In conclusion, in contrast to our hypothesis, we found that triage is largely determined by mechanism of injury regardless of injury severity. High rates of undertriage are largely due to the undertriage of fall-related injuries, which occurs in both younger and older adults. Patients injured after MVCs and penetrating trauma victims are brought to trauma centers regardless of injury severity, resulting in high rates of overtriage. These findings suggest an opportunity to improve trauma system performance.

    Abstract

    To estimate global surgical volume in 2012 and compare it with estimates from 2004.For the 194 Member States of the World Health Organization, we searched PubMed for studies and contacted key informants for reports on surgical volumes between 2005 and 2012. We obtained data on population and total health expenditure per capita for 2012 and categorized Member States as very-low, low, middle and high expenditure. Data on caesarean delivery were obtained from validated statistical reports. For Member States without recorded surgical data, we estimated volumes by multiple imputation using data on total health expenditure. We estimated caesarean deliveries as a proportion of all surgery.We identified 66 Member States reporting surgical data. We estimated that 312.9 million operations (95% confidence interval, CI: 266.2-359.5) took place in 2012, an increase from the 2004 estimate of 226.4 million operations. Only 6.3% (95% CI: 1.7-22.9) and 23.1% (95% CI: 14.8-36.7) of operations took place in very-low- and low-expenditure Member States representing 36.8% (2573 million people) and 34.2% (2393 million people) of the global population of 7001 million people, respectively. Caesarean deliveries comprised 29.6% (5.8/19.6 million operations; 95% CI: 9.7-91.7) of the total surgical volume in very-low-expenditure Member States, but only 2.7% (5.1/187.0 million operations; 95% CI: 2.2-3.4) in high-expenditure Member States.Surgical volume is large and growing, with caesarean delivery comprising nearly a third of operations in most resource-poor settings. Nonetheless, there remains disparity in the provision of surgical services globally.

  • Variability in mortality following caesarean delivery, appendectomy, and groin hernia repair in low-income and middle-income countries: a systematic review and analysis of published data LANCET GLOBAL HEALTH Uribe-Leitz, T., Jaramillo, J., Maurer, L., Fu, R., Esquivel, M. M., Gawande, A. A., Haynes, A. B., Weiser, T. G. 2016; 4 (3): E165-E174

    Abstract

    Surgical interventions occur at lower rates in resource-poor settings, and complication and death rates following surgery are probably substantial but have not been well quantified. A deeper understanding of outcomes is a crucial step to ensure that high quality accompanies increased global access to surgical care. We aimed to assess surgical mortality following three common surgical procedures-caesarean delivery, appendectomy, and groin (inguinal and femoral) hernia repair-to quantify the potential risks of expanding access without simultaneously addressing issues of quality and safety.We collected demographic, health, and economic data for 113 countries classified as low income or lower-middle income by the World Bank in 2005. We did a systematic review of Ovid, MEDLINE, PubMed, and Scopus from Jan 1, 2000, to Jan 15, 2015, to identify studies in these countries reporting all-cause mortality following the three commonly undertaken operations. Reports from governmental and other agencies were also identified and included. We modelled surgical mortality rates for countries without reported data using a two-step multiple imputation method. We first used a fully conditional specification (FCS) multiple imputation method to establish complete datasets for all missing variables that we considered potentially predictive of surgical mortality. We then used regression-based predictive mean matching imputation methods, specified within the multiple imputation FCS method, for selected predictors for each operation using the completed dataset to predict mortality rates along with confidence intervals for countries without reported mortality data. To account for variability in data availability, we aggregated results by subregion and estimated surgical mortality rates.From an initial 1302 articles and reports identified, 247 full-text articles met our inclusion criteria, and 124 provided data for surgical mortality for at least one of the three selected operations. We identified 42 countries with mortality data for at least one of the three procedures. Median reported mortality was 7·9 per 1000 operations for caesarean delivery (IQR 2·8-19·9), 2·2 per 1000 operations for appendectomy (0·0-17·2), and 4·9 per 1000 operations for groin hernia (0·0-11·7). Perioperative mortality estimates by subregion ranged from 2·8 (South Asia) to 50·2 (East Asia) per 1000 caesarean deliveries, 2·4 (South Asia) to 54·0 (Central sub-Saharan Africa) per 1000 appendectomies, and 0·3 (Andean Latin America) to 25·5 (Southern sub-Saharan Africa) per 1000 hernia repairs.All-cause postoperative mortality rates are exceedingly variable within resource-constrained environments. Efforts to expand surgical access and provision of services must include a strong commitment to improve the safety and quality of care.None.

  • Trauma center care is associated with reduced readmissions after injury. journal of trauma and acute care surgery Staudenmayer, K., Weiser, T. G., Maggio, P. M., Spain, D. A., Hsia, R. Y. 2016; 80 (3): 412-418

    Abstract

    Trauma center care has been associated with improved mortality. It is not known if access to trauma center care is also associated with reduced readmissions. We hypothesized that receiving treatment at a trauma center would be associated with improved care and therefore would be associated with reduced readmission rates.We conducted a retrospective analysis of all hospital visits in California using the Office of Statewide Health Planning and Development Database from 2007-2008. All hospital admissions and emergency department visits associated with injury were longitudinally linked. Regions were categorized by whether or not they had trauma centers. We excluded all patients younger than 18 years of age. We performed univariate and multivariate regression analyses to determine if readmissions were associated with patient characteristics, length of stay for initial hospitalization, trauma center access, and triage patterns.A total of 211,504 patients were included in the analysis. Of these, 5,094 (2%) died during the index hospitalization. Of those who survived their initial hospitalization, 79,123 (38%) experienced one or more readmissions to any hospital within one year. The majority of these were one-time readmissions (62%) but 38% experienced multiple readmissions. Over 67% of readmissions were unplanned and 8% of readmissions were for a trauma. After controlling for patient variables known to be associated with readmissions, primary triage to a trauma center was associated with a lower odds of readmission (OR 0.89, p<0.001). The effect of transport to a trauma center remained significantly associated with decreased odds of readmission at one year (OR 0.96, p<0.001).Readmissions after injury are common and are often unscheduled. While patient factors play a role in this, care at a trauma center is also associated with decreased odds for re-admission, even when controlling for severity of injury. This suggests that the benefits of trauma center care extend beyond improvements in mortality to improved long-term outcomes.Economic/Decision LEVEL OF EVIDENCE: Level IV.

  • Uninsured status may be more predictive of outcomes among the severely injured than minority race INJURY-INTERNATIONAL JOURNAL OF THE CARE OF THE INJURED Gerry, J. M., Weiser, T. G., Spain, D. A., Staudenmayer, K. L. 2016; 47 (1): 197-202

    Abstract

    Worse outcomes in trauma in the United States have been reported for both the uninsured and minority race. We sought to determine whether disparities would persist among severely injured patients treated at trauma centres where standard triage trauma protocols limit bias from health systems and providers.We performed a retrospective analysis of the 2010-2012 National Sample Program from the National Trauma Databank, which is a nationally representative sample of trauma centre performance in the United States. The database was screened for adults ages 18-64 who had a known insurance status. Outcomes measured were in-hospital mortality and post-hospital care.There were 739,149 injured patients included in the analysis. Twenty-eight percent were uninsured, and 34 percent were of minority race. In the adjusted analysis, uninsured status (OR 1.60, 1.29-1.98, p<0.001) and black race (OR 1.24, 1.04-1.49, p=0.019) were significant predictors of mortality. Only uninsured status was a significant negative predictor of post-hospital care (OR 0.43, 0.36-0.51, p<0.001). As injury severity increased, only insurance status was a significant predictor of both increased mortality (OR 1.68, 1.29-2.19, p<0.001) and decreased post-hospital care (OR 0.45, 0.32-0.63, p<0.001).Uninsured status is independently associated with higher in-hospital mortality and decreased post-hospital care in patients with severe injuries in a nationally representative sample of trauma centres in the United States. Increased in-hospital mortality is likely due to endogenous patient factors while decreased post-hospital care is likely due to economic constraints. Minority race is less of a factor influencing disparate outcomes among the severely injured.

  • Relationship Between Cesarean Delivery Rate and Maternal and Neonatal Mortality. JAMA Molina, G., Weiser, T. G., Lipsitz, S. R., Esquivel, M. M., Uribe-Leitz, T., Azad, T., Shah, N., Semrau, K., Berry, W. R., Gawande, A. A., Haynes, A. B. 2015; 314 (21): 2263-2270

    Abstract

    Based on older analyses, the World Health Organization (WHO) recommends that cesarean delivery rates should not exceed 10 to 15 per 100 live births to optimize maternal and neonatal outcomes.To estimate the contemporary relationship between national levels of cesarean delivery and maternal and neonatal mortality.Cross-sectional, ecological study estimating annual cesarean delivery rates from data collected during 2005 to 2012 for all 194 WHO member states. The year of analysis was 2012. Cesarean delivery rates were available for 54 countries for 2012. For the 118 countries for which 2012 data were not available, the 2012 cesarean delivery rate was imputed from other years. For the 22 countries for which no cesarean rate data were available, the rate was imputed from total health expenditure per capita, fertility rate, life expectancy, percent of urban population, and geographic region.Cesarean delivery rate.The relationship between population-level cesarean delivery rate and maternal mortality ratios (maternal death from pregnancy related causes during pregnancy or up to 42 days postpartum per 100,000 live births) or neonatal mortality rates (neonatal mortality before age 28 days per 1000 live births).The estimated number of cesarean deliveries in 2012 was 22.9 million (95% CI, 22.5 million to 23.2 million). At a country-level, cesarean delivery rate estimates up to 19.1 per 100 live births (95% CI, 16.3 to 21.9) and 19.4 per 100 live births (95% CI, 18.6 to 20.3) were inversely correlated with maternal mortality ratio (adjusted slope coefficient, -10.1; 95% CI, -16.8 to -3.4; P = .003) and neonatal mortality rate (adjusted slope coefficient, -0.8; 95% CI, -1.1 to -0.5; P < .001), respectively (adjusted for total health expenditure per capita, population, percent of urban population, fertility rate, and region). Higher cesarean delivery rates were not correlated with maternal or neonatal mortality at a country level. A sensitivity analysis including only 76 countries with the highest-quality cesarean delivery rate information had a similar result: cesarean delivery rates greater than 6.9 to 20.1 per 100 live births were inversely correlated with the maternal mortality ratio (slope coefficient, -21.3; 95% CI, -32.2 to -10.5, P < .001). Cesarean delivery rates of 12.6 to 24.0 per 100 live births were inversely correlated with neonatal mortality (slope coefficient, -1.4; 95% CI, -2.3 to -0.4; P = .004).National cesarean delivery rates of up to approximately 19 per 100 live births were associated with lower maternal or neonatal mortality among WHO member states. Previously recommended national target rates for cesarean deliveries may be too low.

    Abstract

    We previously identified a range of 4344-5028 annual operations per 100,000 people to be related to desirable health outcomes. From this and other evidence, the Lancet Commission on Global Surgery recommends a minimum rate of 5000 operations per 100,000 people. We evaluate rates of growth and estimate the time it will take to reach this minimum surgical rate threshold.We aggregated country-level surgical rate estimates from 2004 to 2012 into the twenty-one Global Burden of Disease (GBD) regions. We calculated mean rates of surgery proportional to population size for each year and assessed the rate of growth over time. We then extrapolated the time it will take each region to reach a surgical rate of 5000 operations per 100,000 population based on linear rates of change.All but two regions experienced growth in their surgical rates during the past 8 years. Fourteen regions did not meet the recommended threshold in 2012. If surgical capacity continues to grow at current rates, seven regions will not meet the threshold by 2035. Eastern Sub-Saharan Africa will not reach the recommended threshold until 2124.The rates of growth in surgical service delivery are exceedingly variable. At current rates of surgical and population growth, 6.2 billion people (73 % of the world's population) will be living in countries below the minimum recommended rate of surgical care in 2035. A strategy for strengthening surgical capacity is essential if these targets are to be met in a timely fashion as part of the integrated health system development.

  • Proposed Minimum Rates of Surgery to Support Desirable Health Outcomes: An Observational Study Based on Three Strategies WORLD JOURNAL OF SURGERY Esquivel, M.

    Abstract

    The global volume of surgery is estimated at 312.9 million operations annually, but rates of surgery vary dramatically. Identifying surgical rates associated with improved health outcomes would be useful for benchmarking and targeted health system strengthening.We identified rates of surgery associated with a life expectancy (LE) of 74-75 years, a maternal mortality ratio (MMR) of less than or equal to 100 per 100,000 live births, and the estimated need for surgery in the seven global burden of disease (GBD) super-regions based on the prevalence of surgical conditions. We compared our findings to surgical rates from Chile, China, Costa Rica, and Cuba ("4C"), countries with moderate resources but high health outcomes.The median surgical rates associated with LE of 74-75 years (N = 17) and MMR below 100 (N = 109) are 4392 (IQR 2897-4873) and 5028 (IQR 4139-6778) operations per 100,000 people annually, respectively. The mean surgical rate estimated for the seven super-regions was 4723 (95 % CI 3967-5478) operations per 100,000 people annually. The "4C" countries had a mean surgical rate of 4344 (95 % CI 2620-6068) operations per 100,000 people annually. Thirteen of the twenty-one GBD regions, accounting for 78 % of the world's population, do not achieve rates of surgery at the lowest end of this range.We identified a narrow range of surgical rates associated with important health indicators. This target range can be used for benchmarking of surgical services, and as part of a policy aimed at strengthening health care systems and surgical capacity.

  • The role of facility-based surgical services in addressing the national burden of disease in New Zealand: An index of surgical incidence based on country-specific disease prevalence SURGERY Hider, P., Wilson, L., Rose, J., Weiser, T. G., Gruen, R., Bickler, S. W. 2015; 158 (1): 44-54

    Abstract

    Surgery is a crucial component of health systems, yet its contribution has been difficult to define. We linked national hospital service utilization with national epidemiologic data to describe the use of surgical procedures in the management of a broad spectrum of conditions.We compiled International Classification of Diseases-10-Australian Modification codes from the New Zealand National Minimum Dataset, 2008-2011. Using primary cause of admission, we aggregated hospitalizations into 119 disease states and 22 disease subcategories of the World Health Organization Global Health Estimate (GHE). We queried each hospitalization for any surgical procedure in a binary manner to determine the volume of surgery for each disease state. Surgical procedures were defined as requiring general or neuroaxial anesthesia. We then divided the volume of surgical cases by counts of disease prevalence from the Global Burden of Disease Study 2010 to determine annual surgical incidence.Between 2008 and 2011, there were 1,108,653 hospital admissions with 275,570 associated surgical procedures per year. Surgical procedures were associated with admissions for all 22 GHE disease subcategories and 116 of 119 GHE disease states. The sub-categories with the largest surgical case volumes were Unintentional Injuries (48,073), Musculoskeletal Diseases (38,030), and Digestive Diseases (27,640). Surgical incidence ranged widely by individual disease states with the highest in: Other Neurological Conditions, Abortion, Appendicitis, Obstructed Labor, and Maternal Sepsis.This study confirms that surgical care is required across the entire spectrum of GHE disease subcategories, illustrating a critical role in health systems. Surgical incidence might be useful as an index to estimate the need for surgical procedures in other populations.

    Abstract

    More than 2 billion people are unable to receive surgical care based on operating theatre density alone. The vision of the Lancet Commission on Global Surgery is universal access to safe, affordable surgical and anaesthesia care when needed. We aimed to estimate the number of individuals worldwide without access to surgical services as defined by the Commission's vision.We modelled access to surgical services in 196 countries with respect to four dimensions: timeliness, surgical capacity, safety, and affordability. We built a chance tree for each country to model the probability of surgical access with respect to each dimension, and from this we constructed a statistical model to estimate the proportion of the population in each country that does not have access to surgical services. We accounted for uncertainty with one-way sensitivity analyses, multiple imputation for missing data, and probabilistic sensitivity analysis.At least 4·8 billion people (95% posterior credible interval 4·6-5·0 [67%, 64-70]) of the world's population do not have access to surgery. The proportion of the population without access varied widely when stratified by epidemiological region: greater than 95% of the population in south Asia and central, eastern, and western sub-Saharan Africa do not have access to care, whereas less than 5% of the population in Australasia, high-income North America, and western Europe lack access.Most of the world's population does not have access to surgical care, and access is inequitably distributed. The near absence of access in many low-income and middle-income countries represents a crisis, and as the global health community continues to support the advancement of universal health coverage, increasing access to surgical services will play a central role in ensuring health care for all.None.

    Abstract

    The World Bank will publish the nine volumes of Disease Control Priorities, 3rd edition, in 2015-16. Volume 1--Essential Surgery--identifies 44 surgical procedures as essential on the basis that they address substantial needs, are cost effective, and are feasible to implement. This report summarises and critically assesses the volume's five key findings. First, provision of essential surgical procedures would avert about 1·5 million deaths a year, or 6-7% of all avertable deaths in low-income and middle-income countries. Second, essential surgical procedures rank among the most cost effective of all health interventions. The surgical platform of the first-level hospital delivers 28 of the 44 essential procedures, making investment in this platform also highly cost effective. Third, measures to expand access to surgery, such as task sharing, have been shown to be safe and effective while countries make long-term investments in building surgical and anaesthesia workforces. Because emergency procedures constitute 23 of the 28 procedures provided at first-level hospitals, expansion of access requires that such facilities be widely geographically diffused. Fourth, substantial disparities remain in the safety of surgical care, driven by high perioperative mortality rates including anaesthesia-related deaths in low-income and middle-income countries. Feasible measures, such as WHO's Surgical Safety Checklist, have led to improvements in safety and quality. Fifth, the large burden of surgical disorders, cost-effectiveness of essential surgery, and strong public demand for surgical services suggest that universal coverage of essential surgery should be financed early on the path to universal health coverage. We point to estimates that full coverage of the component of universal coverage of essential surgery applicable to first-level hospitals would require just over US$3 billion annually of additional spending and yield a benefit-cost ratio of more than 10:1. It would efficiently and equitably provide health benefits, financial protection, and contributions to stronger health systems.

    Abstract

    It was previously estimated that 234·2 million operations were performed worldwide in 2004. The association between surgical rates and population health outcomes is not clear. We re-estimated global surgical volume to track changes over time and assess rates associated with healthy populations.We gathered demographic, health, and economic data for 194 WHO member states. Surgical volumes were obtained from published studies and other reports from 2005 onwards. We estimated rates of surgery for all countries without available data based on health expenditure in 2012 and assessed the proportion of surgery comprised by caesarean delivery. The rate of surgery was plotted against life expectancy to describe the association between surgical care and this health indicator.We identified 66 countries reporting surgical data between 2005 and 2013. We estimate that 312·9 million operations (95% CI 266·2-359·5) took place in 2012-a 33·6% increase over 8 years; the largest proportional increase occurred in countries spending US$400 or less per capita on health care. Caesarean delivery comprised 29·8% (5·8 million operations) of the total surgical volume in poor health expenditure countries compared with 10·8% (7·8 million operations) in low health expenditure countries and 2·7% (5·1 million operations) in high health expenditure countries. We noted a correlation between increased life expectancy and increased surgical rates up to 1533 operations per 100 000 people, with significant but less dramatic improvement above this rate.Surgical volume is large and continues to grow in all economic environments. A single procedure-caesarean delivery-comprised almost a third of surgical volume in the most resource-limited settings. Surgical care is an essential part of health care and is associated with increased life expectancy, yet many low-income countries fail to achieve basic levels of service. Improvements in capacity and delivery of surgical services must be a major component of health system strengthening.None.

    Abstract

    While surgical interventions occur at lower rates in resource-poor settings, rates of complication and death after surgery are substantial but have not been well quantified. A deeper understanding of outcomes is a crucial step to ensure that quality accompanies increased global access to surgical care. We aimed to assess mortality following surgery to assess the risks of such interventions in these environments.We collected the most recent demographic, health, and economic data from WHO for 114 countries classified as low-income or lower-middle-income according to the World Bank in 2005. We searched OVID, MedLine, PubMed, and SCOPUS to identify studies in these countries reporting all-cause mortality after three commonly performed operations: caesarean delivery, appendectomy, and groin hernia repair. Reports from governmental and other agencies were also identified. We modelled surgical mortality rates for countries without reported data with the lasso technique that performs continuous variable subset selection to avoid model overfitting. We validated our model against known case fatality rates for caesarean delivery. We aggregated mortality results by subregion to account for variability in data availability. We then created collective surgical case fatality rates by WHO region.We identified 42 countries with mortality data for at least one of the three procedures. Median reported mortality rates were 7·7 per 1000 operations for caesarean delivery (IQR 3-14), 4·0 per 1000 operations for appendectomy (IQR 0-17), and 4·7 per 1000 operations for hernia groin (IQR 0-13); all recorded deaths occurred during the same admission to hospital as the operation. Based on our model, case fatality rate estimates by subregion ranged from 0·7 (central Europe) to 13·9 (central sub-Saharan Africa) per 1000 caesarean deliveries, 5·6 (central Asia) to 6·4 (central sub-Saharan Africa) per 1000 appendectomies, and 3·5 (tropical Latin America) to 33·9 (central sub-Saharan Africa) per 1000 hernia repairs.All-cause postoperative mortality rates are exceedingly variable within resource-constrained environments, and substantially higher than those in middle-income and high-income settings. Efforts to expand surgical access and provision of services must include a strong commitment to improve the safety and quality of care.None.

  • Proposed minimum rates of surgery to support desirable health outcomes: an observational study based on four strategies. Lancet Esquivel, M. M., Molina, G., Uribe-Leitz, T., Lipsitz, S. R., Rose, J., Bickler, S. W., Gawande, A. A., Haynes, A. B., Weiser, T. G. 2015; 385: S12-?

    Abstract

    The global volume of surgery in 2012 is estimated at 312·9 million operations per year, but rates of surgery vary substantially. Maternal health advocates proposed minimum caesarean delivery rates for benchmarking and to improve perinatal outcomes; however, this has not been done for surgery because the association between rates of surgical care provision as a whole and population health outcomes have not been well described. We use available data to estimate minimum rates of surgery that are associated with important health indicators.We defined surgical operations as procedures done in operating theatres that need general or regional anaesthesia or profound sedation to control pain. We used four strategies to identify rates of surgery based on estimated rates of surgery per country for 2012 associated with life expectancy of 74-75 years; estimated rates of surgery associated with a maternal mortality ratio of less than or equal to 100 per 100 000 live births; estimated minimum need for surgery in the 21 Global Burden of Disease (GBD) regions based on the prevalence of disorders; and surgical rates from the so-called 4C countries (Chile, China, Costa Rica, and Cuba) identified in The Lancet Commission on Global Surgery as exemplary for their achievement of high health status, despite resource limitations.Based on 2012 national surgical rates, countries with reported life expectancy of 74-75 years (n=17) had a median surgical rate of 4392 (IQR 2897-4873) operations per 100 000 population annually. The median surgical rate associated with maternal mortality ratio lower than 100 (n=109) is 5028 (IQR 4139-6778) operations per 100 000 population annually. The median surgical rate estimated for all 21 GBD regions was 4669 (IQR 4339-5291) operations per 100 000 population annually. The 4C countries had a mean surgical rate of 4344 (95% CI 2620-6068) operations per 100 000 population annually. 13 of the 21 GBD regions, accounting for 78% of the world's population, do not achieve the lowest end of the surgical rate range.We identified a surprisingly narrow range of surgical rates associated with important health indicators. This target range can be used for benchmarking of surgical services, and as part of a policy aimed at strengthening health-care systems and surgical capacity.None.

    Abstract

    Recent work has indicated an increase in surgical services, especially in resource poor settings. However, the rate of growth is poorly understood and likely insufficient to meet public health needs. We previously identified a range of 4344 to 5028 operations per 100 000 population annually to be related to desirable health outcomes. From this and other evidence, the Lancet Commission on Global Surgery recommends a minimum rate of 5000 operations per 100 000 population. We evaluate rates of growth in surgery and estimate the time it will take to reach this minimum surgical rate threshold.We aggregated 2004 and 2012 country-level surgical rate estimates into the 21 Global Burden of Disease (GBD) regions. We calculated mean rates of surgery proportional to population size and estimate rate of growth between these years. We then extrapolated the time it will take to reach a surgical rate of 5000 operations per 100 000 population based on linear rates of change.All but two regions (central Europe and southern Latin America) experienced growth in their surgical rates during the past 8 years; the fastest growth occurred in regions with the lowest surgical rates. 14 regions representing 79% of the world's population (5·5 billion people) did not meet the recommended surgical rate threshold in 2012. If surgical capacity grows at current rates, seven regions (central sub-Saharan Africa, east Asia, eastern sub-Saharan Africa, north Africa and middle east, south Asia, southeast Asia, and western sub-Saharan Africa) will not meet the recommended surgical rate threshold by 2035; Eastern Sub-Saharan Africa will not reach this level until 2124.The rates of growth in surgical service delivery are exceedingly variable, but the largest growth rates were noted in the poorest regions. Although this study does not address the quality of care, and rates of surgery are unlikely to change linearly, this exercise is useful to project how many years it could take regions to reach specific surgical rates. At current rates of growth, 4·9 billion people (70% of the world's population) will still be living in countries below the minimum recommended rate of surgery in 2035. A strategy for strengthening surgical capacity is essential if these targets are to be met as part of integrated health system development.None.

  • Avoidable maternal and neonatal deaths associated with improving access to caesarean delivery in countries with low caesarean delivery rates: an ecological modelling analysis. Lancet Molina, G., Esquivel, M. M., Uribe-Leitz, T., Lipsitz, S. R., Azad, T., Shah, N., Semrau, K., Berry, W. R., Gwande, A. A., Weiser, T. G., Haynes, A. B. 2015; 385: S33-?

    Abstract

    Reducing maternal and neonatal deaths are important global health priorities. We have previously shown that up to a country-level caesarean delivery rate (CDRs) of roughly 19·0%, cesarean delivery rates and maternal mortality ratio (MMR) and neonatal mortality rate (NMR) were inversely correlated. We investigated the absolute reductions in maternal and neonatal deaths if countries with low CDR increased their rates to a range of greater than 7·2% but less than or equal to 19·1%.We calculated maternal and neonatal deaths in 2013 and 2012, respectively, for countries with CDR 7·2% or less (N=45) with available data from the World Bank Development Indicators. We modelled the expected reduction in deaths in these countries if they had the 25th and 75th MMR and NMR percentiles observed for countries (N=48) with CDRs ranging from greater than 7·2% but less than or equal to 19·1%. This model assumes that if countries with low CDRs increased their rates of caesarean delivery to greater than 7·2% but less than or equal to 19·1%, they would achieve levels of MMR and NMR observed in countries with those CDRs.We estimate 176 078 (95% CI 163 258-188 898) maternal and 1 117 257 (95% CI 1 033 611-1 200 902) neonatal deaths occurred in 45 countries with low CDRs in 2013 and 2012, respectively. If these countries had the 25th and 75th MMR and NMR percentiles (MMR, IQR 36-190; NMR, 9-24) observed in countries (N=48) with a CDR ranging from greater than 7·2% but less than or equal to 19·1%, there would be a potential reduction of 109 762-163 513 and 279 584-803 129 maternal and neonatal deaths, respectively.Increasing caesarean delivery in countries with low CDRs could avert as many as 163 513 maternal deaths and 803 129 neonatal deaths annually. These findings assume that as health systems develop the capacity to deliver surgical care, there is a concurrent improvement in the quality of care and in the ability to rescue women and neonates who would otherwise die. Improving access to safe caesarean delivery should be a central focus in surgical care globally.None.

  • The role of facility-based surgical services in addressing the national burden of disease in New Zealand: an index of surgical incidence based on country-specific disease prevalence. Lancet Hider, P., Wilson, L., Rose, J., Weiser, T. G., Gruen, R., Bickler, S. W. 2015; 385: S25-?

    Abstract

    Surgery is a crucial component of health systems, yet its actual contribution has been difficult to define. We aimed to link use of national hospital service with national epidemiological surveillance data to describe the use of surgical procedures in the management of a broad spectrum of conditions.We compiled Australian Modification-International Classification of Diseases-10 codes from the New Zealand National Minimum Dataset, 2008-11. Using primary cause of admission, we aggregated admissions to 91 hospitals into 119 disease states and 22 disease subcategories of the WHO Global Health Estimate (GHE). We queried each admission for any surgical procedure in a binary manner to determine the frequency of admitted patients whose care required surgery. Surgical procedures were defined as requiring general or neuroaxial anaesthesia. We then divided the volume of surgical cases by counts of disease prevalence from the GBD 2010 to determine surgical incidence. This study was approved by the University of Otago Human Ethics Committee (Health; Reference Number HD14/42). Raw data was only handled by coauthors with direct affiliation with the New Zealand Ministry of Health.Between 2008 and 2011, there were 1 108 653 hospital admissions with 275 570 associated surgical procedures per year. Surgical procedures were associated with admissions for all 22 GHE disease subcategories and 116 of 119 GHE disease states (excluding intestinal nematode infections, iodine deficiency, and vitamin A deficiency). The subcategories with the largest surgical case volumes were unintentional injuries (48 073), musculoskeletal diseases (38 030), and digestive diseases (27 640), and the subcategories with the smallest surgical case volumes were nutritional deficiencies (13), neonatal conditions (204), and infectious and parasitic diseases (982). Surgical incidence ranged widely by individual disease states with the highest in other neurological conditions, abortion, appendicitis, obstructed labour, and maternal sepsis.This study confirms previous research that surgical care is required across the entire spectrum of GHE disease subcategories, showing the crucial role of operative intervention in health systems. Surgical incidence might be useful as an index to estimate the need for surgical procedures in other populations.None.

  • Beyond the hospital doors: Improving long-term outcomes for elderly trauma patients JOURNAL OF TRAUMA AND ACUTE CARE SURGERY Ayoung-Chee, P. R., Rivara, F. P., Weiser, T., Maier, R. V., Arbabi, S. 2015; 78 (4): 837-843

    Abstract

    Elderly trauma patients (TPs) are the fastest growing trauma population, increasing the need for postacute care rehabilitation. For TP, discharge to skilled nursing facilities (SNFs) has been associated with higher 1-year mortality compared with discharge to inpatient rehabilitation facilities (IRFs) or home. The availability of IRF beds has been decreasing, but the proportion occupied by non-TPs, specifically stroke patients (SPs), has increased. We wanted to better characterize trends in trauma discharges and compare them with a population that is equally dependent on postdischarge rehabilitation. We hypothesized that discharge to SNF is rapidly increasing, while discharge to IRF is declining for trauma, but not for SPs.This is retrospective cohort study of adult trauma and SPs discharged from 2003 to 2009. The National Trauma Data Bank and National Inpatient Sample were used to study TPs and SPs, respectively.Falls became the leading cause of injury, and the proportion of older TPs increased from 23% to 30%. Older TPs discharged to SNF increased from 30.7% in 2003 to 40.8% in 2009 (p < 0.001). TPs were 34% (adjusted relative risk [RR], 1.34; 95% confidence interval [CI], 1.15-1.57) more likely to be discharged to an SNF and 36% (adjusted RR, 0.64; 95% CI, 0.48-0.85) less likely to be discharged to an IRF. From 2003 to 2009, SPs were 78% more likely to be discharged to an IRF (adjusted RR, 1.78; 95% CI, 1.74-1.82). The largest absolute increase in SP discharges to IRFs occurred the year following implementation of the stroke center certification program.For TPs, there was a significant increase in SNF discharges and a decrease in IRF discharges. During the same period, after implementation of stroke center certification, SPs were more likely to be discharged to an IRF. Future research should focus on evaluating which postacute care setting is most effective in providing rehabilitation for TPs and adjusting our discharge efforts to improve long-term outcomes.Prognostic and epidemiologic study, level III.

  • Timing and cost of scaling up surgical services in low-income and middle-income countries from 2012 to 2030: a modelling study LANCET GLOBAL HEALTH Verguet, S., Alkire, B. C., Bickler, S. W., Lauer, J. A., Uribe-Leitz, T., Molina, G., Weiser, T. G., Yamey, G., Shrime, M. G. 2015; 3: S28-S37

    Abstract

    Given the large burden of surgical conditions and the crosscutting nature of surgery, scale-up of basic surgical services is crucial to health-system strengthening. The Lancet Commission on Global Surgery proposed that, to meet populations' needs, countries should achieve 5000 major operations per 100 000 population per year. We modelled the possible scale-up of surgical services in 88 low-income and middle-income countries with a population greater than 1 million from 2012 to 2030 at various rates and quantified the associated costs.Major surgery includes any intervention within an operating room involving tissue manipulation and anaesthesia. We used estimates for the number of major operations achieved per country annually and the number of operating rooms per region, and data from Mongolia and Mexico for trends in the number of operations. Unit costs included a cost per operation, proxied by caesarean section cost estimates; hospital construction data were used to estimate cost per operating room construction. We determined the year by which each country would achieve the Commission's target. We modelled three scenarios for the scale-up rate: actual rates (5·1% per year) and two "aspirational" rates, the rates achieved by Mongolia (8·9% annual) and Mexico (22·5% annual). We subsequently estimated the associated costs.About half of the 88 countries would achieve the target by 2030 at actual rates of improvements, with up to two-thirds if the rate were increased to Mongolian rates. We estimate the total costs of achieving scale-up at US$300-420 billion (95% UI 190-600 billion) over 2012-30, which represents 4-8% of total annual health expenditures among low-income and lower middle-income countries and 1% among upper middle-income countries.Scale-up of surgical services will not reach the target of 5000 operations per 100 000 by 2030 in about half of low-income and middle-income countries without increased funding, which countries and the international community must seek to achieve expansion of quality surgical services.None.

  • Estimated need for surgery worldwide based on prevalence of diseases: a modelling strategy for the WHO Global Health Estimate LANCET GLOBAL HEALTH Rose, J., Weiser, T. G., Hider, P., Wilson, L., Gruen, R. L., Bickler, S. W. 2015; 3: S13-S20

    Abstract

    Surgery is a foundational component of health-care systems. However, previous efforts to integrate surgical services into global health initiatives do not reflect the scope of surgical need and many health systems do not provide essential interventions. We estimate the minimum global volume of surgical need to address prevalent diseases in 21 epidemiological regions from the Global Burden of Disease Study 2010 (GBD).Prevalence data were obtained from GBD 2010 and organised into 119 disease states according to the WHO's Global Health Estimate (GHE). These data, representing 187 countries, were then apportioned into the 21 GBD epidemiological regions. Using previously defined values for the incident need for surgery for each of the 119 GHE disease states, we calculate minimum global need for surgery based on the prevalence of each condition in each region.We estimate that at least 321·5 million surgical procedures would be needed to address the burden of disease for a global population of 6·9 billion in 2010. Minimum rates of surgical need vary across regions, ranging from 3383 operations per 100 000 in central Latin America to 6495 operations per 100 000 in western sub-Saharan Africa. Global surgical need also varied across subcategories of disease, ranging from 131 412 procedures for nutritional deficiencies to 45·8 million procedures for unintentional injuries.The estimated need for surgical procedures worldwide is large and addresses a broad spectrum of disease states. Surgical need varies between regions of the world according to disease prevalence and many countries do not meet the basic needs of their populations. These estimates could be useful for policy makers, funders, and ministries of health as they consider how to incorporate surgical capacity into health systems.US National Institutes of Health.

    Abstract

    To quantify the burden of selected congenital anomalies in low and middle-income countries (LMICs) that could be reduced should surgical programmes cover the entire population with access to quality care.Burden of disease and epidemiological modelling.LMICs from all global regions.All prevalent cases of selected congenital anomalies at birth in 2010.Disability-adjusted life years (DALYs).Surgical programmes for three congenital conditions were analysed: clefts (lip and palate); congenital heart anomalies; and neural tube defects. Data from the Global Burden of Disease 2010 Study were used to estimate the combination of fatal burden that could be addressed by surgical care and the additional long-term non-fatal burden associated with increased survival.Of the estimated 21.6 million DALYs caused by these three conditions in LMICs, 12.4 million DALYs (57%) are potentially addressable by surgical care among the population born with such conditions. Neural tube defects have the largest potential with 76% of burden amenable by surgery, followed by clefts (59%) and congenital heart anomalies (49%). Sub-Saharan Africa and South Asia have the greatest proportion of surgically addressable burden for clefts (68%), North Africa and Middle East for congenital heart anomalies (73%), and South Asia for neural tube defects (81%).There is an important and neglected role surgical programmes can play in reducing the burden of congenital anomalies in LMICs.

  • Surgically avertable burden of digestive diseases at first-level hospitals in low and middle-income regions. Surgery Higashi, H., Barendregt, J. J., Kassebaum, N. J., Weiser, T. G., Bickler, S. W., Vos, T. 2015; 157 (3): 411-419

    Abstract

    To quantify the burden of digestive diseases avertable by surgical care at first-level hospitals in low- and middle-income countries (LMICs).We examined 4 digestive diseases from the Global Burden of Disease (GBD) 2010 STUDY: Appendicitis, intestinal obstruction, inguinal and femoral hernia, and gallbladder and bile duct disease. Using demographic and epidemiologic data from the GBD 2010 STUDY, we calculated the potential decrease in burden of digestive diseases if quality surgical services were available universally and accessible at first-level hospitals. The lowest case fatality rates for each age and sex grouping from all GBD regions were assumed to reflect the best possible state of full surgical coverage and treatment. These best scenario rates were applied to the GBD 2010 results from all LMIC regions to estimate surgically avertable burden.Overall, 4.8 million disability-adjusted life-years (DALYs) or 65% of burden related to the 4 digestive diseases are avertable potentially with first-level surgical care in LMICs. Sub-Saharan Africa has the greatest avertable burden in absolute DALYs (1.7 million) and avertable proportion (83%). Intestinal obstruction accounted for the largest portion of avertable burden among the 4 digestive diseases (2.2 million DALYs; 64% avertable).Improving the capacity of surgical services at first-level hospitals is essential for averting the burden of digestive diseases in LMICs. Practicable strategies for scaling up surgical capacities in rural districts are available potentially, which must be given due attention.

  • Adding insult to injury: discontinuous insurance following spine trauma. journal of bone and joint surgery. American volume Kastenberg, Z. J., Hurley, M. P., Weiser, T. G., Cole, T. S., Staudenmayer, K. L., Spain, D. A., Ratliff, J. K. 2015; 97 (2): 141-146

    Abstract

    Spine trauma patients may represent a group for whom insurance fails to provide protection from catastrophic medical expenses, resulting in the transfer of financial burden onto individual families and public payers. This study compares the rate of insurance discontinuation for patients who underwent surgery for traumatic spine injury with and without spinal cord injury with the rate for matched control subjects.We used the MarketScan database to perform a retrospective cohort study of privately insured spine trauma patients who underwent surgery from 2006 to 2010. Kaplan-Meier survival analysis was used to assess the time to insurance discontinuation. Cox proportional-hazards regression was used to determine hazard ratios for insurance discontinuation among spine trauma patients compared with the matched control population.The median duration of existing insurance coverage was 20.2 months for those with traumatic spinal cord injury, 25.6 months for those with traumatic spine injury without spinal cord injury, and 48.0 months for the matched control cohort (log-rank p < 0.0001). After controlling for multiple covariates, the hazard ratios for discontinuation of insurance were 2.02 (95% CI [confidence interval], 1.83 to 2.23) and 2.78 (95% CI, 2.31 to 3.35) for the trauma patients without and with spinal cord injury, respectively, compared with matched controls.Rates of insurance discontinuation are significantly higher for trauma patients with severe spine injury compared with the uninjured population, indicating that patients with disabling injuries are at increased risk for loss of insurance coverage.

    Abstract

    To quantify the burden of maternal and neonatal conditions in low- and middle-income countries (LMICs) that could be averted by full access to quality first-level obstetric surgical procedures.Burden of disease and epidemiological modelling.LMICs from all global regions.The entire population in 2010.We included five conditions in our analysis: maternal haemorrhage; obstructed labour; obstetric fistula; abortion(1) ; and neonatal encephalopathy. Demographic and epidemiological data were obtained from the Global Burden of Disease 2010 study. We split the disability-adjusted life years (DALYs) of these conditions into surgically 'avertable' and 'non-avertable' burdens. We applied the lowest age-specific fatality rates from all global regions to each LMIC region to estimate the avertable deaths, assuming that the differences of death rates between each region and the lowest rates reflect the gap in surgical care.Deaths and DALYs avertable.Of the estimated 56.6 million DALYs (i.e. 56.6 million years of healthy life lost) of the selected five conditions, 21.1 million DALYs (37%) are avertable by full coverage of quality obstetric surgery in LMICs. The avertable burden in absolute term is substantial given the size of burden of these conditions in LMICs. Neonatal encephalopathy constitutes the largest portion of avertable burden (16.2 million DALYs) among the five conditions, followed by abortion (2.1 million DALYs).Improving access to quality surgical care at first-level hospitals could reduce a tremendous burden of maternal and neonatal conditions in LMICs.

    Abstract

    Injuries accounted for 11 % of the global burden of disease in 2010. This study aimed to quantify the burden of injury in low- and middle-income countries (LMICs) that could be averted if basic surgical services were made available and accessible to the entire population.We examined all causes of injury from the Global Burden of Disease 2010 Study. We split the disability-adjusted life years (DALYs) for these conditions between surgically "avertable" and "nonavertable" burdens. For estimating the avertable fatal burden, we applied the lowest fatality rates among the 21 epidemiologic regions to each LMIC region, assuming that the differences in death rates between each region and the lowest rates reflect the gap in surgical care. We adjusted for fatal cases that occur prior to reaching hospitals as they are not surgically avertable. Similarly, we applied the lowest nonfatal burden per case to each LMIC region.Overall, 21 % of the injury burden in LMICs was potentially avertable by basic surgical care (52.3 million DALYs). The avertable proportion was greater for deaths than for nonfatal burden (23 vs. 20 %), suggesting that surgical services for injuries more effectively save lives than ameliorate disability. Sub-Saharan Africa had the largest proportion of potentially avertable burden (25 %). South Asia had the highest total avertable DALYs (17.4 million). Road injury comprised the largest total avertable burden in LMICs (16.1 million DALYs).Basic surgical care has the potential to play a major role in reducing the injury-related burden in LMICs.

    Abstract

    The perception of surgery as expensive and complex might be a barrier to its widespread acceptance in global health efforts. We did a systematic review and analysis of cost-effectiveness studies that assess surgical interventions in low-income and middle-income countries to help quantify the potential value of surgery.We searched Medline for all relevant articles published between Jan 1, 1996 and Jan 31, 2013, and searched the reference lists of retrieved articles. We converted all results to 2012 US$. We extracted cost-effectiveness ratios (CERs) and appraised economic assessments for their methodological quality using the 10-point Drummond checklist.Of the 584 identified studies, 26 met full inclusion criteria. Together, these studies gave 121 independent CERs in seven categories of surgical interventions. The median CER of circumcision ($13·78 per disability-adjusted life year [DALY]) was similar to that of standard vaccinations ($12·96-25·93 per DALY) and bednets for malaria prevention ($6·48-22·04 per DALY). Median CERs of cleft lip or palate repair ($47·74 per DALY), general surgery ($82·32 per DALY), hydrocephalus surgery ($108·74 per DALY), and ophthalmic surgery ($136 per DALY) were similar to that of the BCG vaccine ($51·86-220·39 per DALY). Median CERs of caesarean sections ($315·12 per DALY) and orthopaedic surgery ($381·15 per DALY) are more favourable than those of medical treatment for ischaemic heart disease ($500·41-706·54 per DALY) and HIV treatment with multidrug antiretroviral therapy ($453·74-648·20 per DALY).Our findings suggest that many essential surgical interventions are cost-effective or very cost-effective in resource-poor countries. Quantification of the economic value of surgery provides a strong argument for the expansion of global surgery's role in the global health movement. However, economic value should not be the only argument for resource allocation--other organisational, ethical, and political arguments can also be made for its inclusion.

  • Evaluation of a large-scale donation of Lifebox pulse oximeters to non-physician anaesthetists in Uganda ANAESTHESIA Finch, L. C., Kim, R. Y., Ttendo, S., Kiwanuka, J. K., Walker, I. A., Wilson, I. H., Weiser, T. G., Berry, W. R., Gawande, A. A. 2014; 69 (5): 445-451

    Abstract

    Pulse oximetry is widely accepted as essential monitoring for safe anaesthesia, yet is frequently unavailable in resource-limited settings. The Lifebox pulse oximeter, and associated management training programme, was delivered to 79 non-physician anaesthetists attending the 2011 Uganda Society of Anaesthesia Annual Conference. Using a standardised assessment, recipients were tested for their knowledge of oximetry use and hypoxia management before, immediately following and 3-5 months after the training. Before the course, the median (IQR [range]) test score for the anaesthetists was 36 (34-39 [26-44]) out of a maximum of 50 points. Immediately following the course, the test score increased to 41 (38-43 [25-47]); p < 0.0001 and at the follow-up visit at 3-5 months it was 41 (39-44 [33-49]); p = 0.001 compared with immediate post-training test scores, and 75/79 (95%) oximeters were in routine clinical use. This method of introduction resulted in a high rate of uptake of oximeters into clinical practice and a demonstrable retention of knowledge in a resource-limited setting.

  • The epidemiology of trauma-related mortality in the United States from 2002 to 2010. journal of trauma and acute care surgery Sise, R. G., Calvo, R. Y., Spain, D. A., Weiser, T. G., Staudenmayer, K. L. 2014; 76 (4): 913-920

    Abstract

    Epidemiologic trends in trauma-related mortality in the United States require updating and characterization. We hypothesized that during the past decade, there have been changing trends in mortality that are associated with multiple public health and health care-related factors.Multiple sources were queried for the period of 2002 to 2010: the National Trauma Data Bank, the National Centers for Disease Control, the National Highway Traffic Safety Administration, the Nationwide Emergency Department Sample, and the US Census Bureau. The incidence of injury and mortality for motor vehicle traffic (MVT) collisions, firearms, and falls were determined using National Centers for Disease Control data. National Highway Traffic Safety Administration data were used to determine motor vehicle collision information. Injury severity data were derived from the Nationwide Emergency Department Sample and National Trauma Data Bank. Analysis of mortality trends by year was performed using the Cochran-Armitage test for trend. Time-trend multivariable Poisson regression was used to determine risk-adjusted mortality over time.From 2002 to 2010, the total trauma-related mortality decreased by 6% (p < 0.01). However, mortality trends differed by mechanism. There was a 27% decrease in the MVT death rate associated with a 20% decrease in motor vehicle collisions, 19% decrease in the number of occupant injuries per collision, lower injury severity, and improved outcomes at trauma centers. While firearm-related mortality remained relatively unchanged, mortality caused by firearm suicides increased, whereas homicide-associated mortality decreased (p < 0.001 for both). In contrast, fall-related mortality increased by 46% (5.95-8.70, p < 0.01).MVT mortality rates have decreased during the last decade, owing in part to decreases in the number and severity of injuries. Conversely, fall-related mortality is increasing and is projected to exceed both MVT and firearm mortality rates should current trends continue. Trauma systems and injury prevention programs will need to take into account these changing trends to best accommodate the needs of the injured population.Epidemiologic study, level III.

  • The role of surgery in global health: analysis of United States inpatient procedure frequency by condition using the global burden of disease 2010 framework. PloS one Rose, J., Chang, D. C., Weiser, T. G., Kassebaum, N. J., Bickler, S. W. 2014; 9 (2)

    Abstract

    The role of surgical care in promoting global health is the subject of much debate. The Global Burden of Disease 2010 study (GBD 2010) offers a new opportunity to consider where surgery fits amongst global health priorities. The GBD 2010 reinforces the DALY as the preferred methodology for determining the relative contribution of disease categories to overall global burden of disease without reference to the likelihood of each category requiring surgery. As such, we hypothesize that the GBD framework underestimates the role of surgery in addressing the global burden of disease.We compiled International Classification of Diseases, Version 9, codes from the United States Nationwide Inpatient Sample from 2010. Using the primary diagnosis code for each hospital admission, we aggregated admissions into GBD 2010 disease sub-categories. We queried each hospitalization for a major operation to determine the frequency of admitted patients whose care required surgery. Major operation was defined according to the Agency for Healthcare Research and Quality (AHRQ). In 2010, 10 million major inpatient operations were performed in the United States, associated with 28.6% of all admissions. Major operations were performed in every GBD disease subcategory (range 0.2%-84.0%). The highest frequencies of operation were in the subcategories of Musculoskeletal (84.0%), Neoplasm (61.4%), and Transport Injuries (43.2%). There was no disease subcategory that always required an operation; nor was there any disease subcategory that never required an operation.Surgical care cuts across the entire spectrum of GBD disease categories, challenging dichotomous traditional classifications of 'surgical' versus 'nonsurgical' diseases. Current methods of measuring global burden of disease do not reflect the fundamental role operative intervention plays in the delivery of healthcare services. Novel methodologies should be aimed at understanding the integration of surgical services into health systems to address the global burden of disease.

    Abstract

    All surgeons want the best, safest care for their patients, but providing this requires the complex coordination of multiple disciplines to ensure that all elements of care are timely, appropriate, and well organized. Quality-improvement initiatives are beginning to lead to improvements in the quality of care and coordination amongst teams in the operating room. As the population ages and patients present with more complex disease pathology, the demands for efficient systematization will increase. Although evidence suggests that postoperative mortality rates are declining, there is substantial room for improvement. Multiple quality metrics are used as surrogates for safe care, but surgical teams--including surgeons, anaesthetists, and nurses--must think beyond these simple interventions if they are to effectively communicate and coordinate in the face of increasing demands.

    Abstract

    Checklists are increasingly being used by surgical teams in the perioperative period to improve clinical care and increase patient safety. In this article, we review some of the mechanisms by which checklists work and evaluate evidence supporting their use.There is a growing body of evidence showing the importance of team-based checklists in clinical care. In multiple complex clinical environments, from the operating room to the intensive care unit, checklists can help ensure adherence to known standards of care and improve communication amongst team members. In addition, the efficacy of checklists is being shown in both developed and developing settings.Checklists can aid clinicians involved in complex processes and multidisciplinary team interactions to improve the quality and safety of care by prompting dialogue and exchange of information.

  • Rates and patterns of death after surgery in the United States, 1996 and 2006 SURGERY Semel, M. E., Lipsitz, S. R., Funk, L. M., Bader, A. M., Weiser, T. G., Gawande, A. A. 2012; 151 (2): 171-182

    Abstract

    Nationwide rates and patterns of death after surgery are unknown.Using the Nationwide Inpatient Sample, we compared deaths within 30 days of admission for patients undergoing surgery in 1996 and 2006. International Classification of Diseases codes were used to identify 2,520 procedures for analysis. We examined the inpatient 30-day death rate for all procedures, procedures with the most deaths, high-risk cardiovascular and cancer procedures, and patients who suffered a recorded complication. We used logistic regression modeling to adjust 1996 mortality rates to the age and gender distributions for patients undergoing surgery in 2006.In 1996, there were 12,573,331 admissions with a surgical procedure (95% confidence interval [CI], 12,560,171-12,586,491) and 224,111 inpatient deaths within 30 days of admission (95% CI, 221,912-226,310). In 2006, there were 14,333,993 admissions with a surgical procedure (95% CI, 14,320,983-14,347,002) and 189,690 deaths (95% CI, 187,802-191,578). Inpatient 30-day mortality declined from 1.68% in 1996 to 1.32% in 2006 (P < .001). Of the 21 procedures with the most deaths in 1996, 15 had significant declines in adjusted mortality in 2006. Among these 15 procedures, 8 had significant declines in operative volume. The inpatient 30-day mortality rate for patients who suffered a complication decreased from 12.10% to 9.84% (P < .001).Nationwide reporting on surgical mortality suggests that the number of inpatient deaths within 30 days of surgery has declined. Additional research to determine the underlying causes for decreased mortality is warranted.

  • Postgame Analysis: Using Video-Based Coaching for Continuous Professional Development JOURNAL OF THE AMERICAN COLLEGE OF SURGEONS Hu, Y., Peyre, S. E., Arriaga, A. F., Osteen, R. T., Corso, K. A., Weiser, T. G., Swanson, R. S., Ashley, S. W., Raut, C. P., Zinner, M. J., Gawande, A. A., Greenberg, C. C. 2012; 214 (1): 115-124

    Abstract

    The surgical learning curve persists for years after training, yet existing continuing medical education activities targeting this are limited. We describe a pilot study of a scalable video-based intervention, providing individualized feedback on intraoperative performance.Four complex operations performed by surgeons of varying experience--a chief resident accompanied by the operating senior surgeon, a surgeon with less than 10 years in practice, another with 20 to 30 years in practice, and a surgeon with more than 30 years of experience--were video recorded. Video playback formed the basis of 1-hour coaching sessions with a peer-judged surgical expert. These sessions were audio recorded, transcribed, and thematically coded.The sessions focused on operative technique--both technical aspects and decision-making. With increasing seniority, more discussion was devoted to the optimization of teaching and facilitation of the resident's technical performance. Coaching sessions with senior surgeons were peer-to-peer interactions, with each discussing his preferred approach. The coach alternated between directing the session (asking probing questions) and responding to specific questions brought by the surgeons, depending on learning style. At all experience levels, video review proved valuable in identifying episodes of failure to progress and troubleshooting alternative approaches. All agreed this tool is a powerful one. Inclusion of trainees seems most appropriate when coaching senior surgeons; it may restrict the dialogue of more junior attendings.Video-based coaching is an educational modality that targets intraoperative judgment, technique, and teaching. Surgeons of all levels found it highly instructive. This may provide a practical, much needed approach for continuous professional development.

  • In-hospital Death following Inpatient Surgical Procedures in the United States, 1996-2006 WORLD JOURNAL OF SURGERY Weiser, T. G., Semel, M. E., Simon, A. E., Lipsitz, S. R., Haynes, A. B., Funk, L. M., Berry, W. R., Gawande, A. A. 2011; 35 (9): 1950-1956

    Abstract

    Over the past decade, improvements in perioperative care have been widely introduced throughout the United States, yet there is no clear indication that the death rate following surgery has improved. We sought to evaluate the number of deaths after surgery in the United States over a 10-year period and to evaluate trends in postoperative mortality.Using the National Hospital Discharge Survey, we identified patients who underwent a surgical procedure and subsequently died in the hospital within 30 days of admission.In 1996 there were 12,250,000 hospitalizations involving surgery, rising to 13,668,000 in 2006. Postoperative deaths, however, declined during this same period, from 201,000 to 156,000 (P < 0.01), giving a postoperative in-hospital death ratio (death per hospitalization) of 1.64 and 1.14% (P < 0.001), respectively, for the two time frames.The death rate following surgery is substantial but appears to have improved. Such mortality statistics provide an essential measure of the public health impact of surgical care. Incorporating mortality statistics following therapeutic intervention is an essential strategy for regional and national surveillance of care delivery.

  • Surgical outcome measurement for a global patient population: Validation of the Surgical Apgar Score in 8 countries SURGERY Haynes, A. B., Regenbogen, S. E., Weiser, T. G., Lipsitz, S. R., Dziekan, G., Berry, W. R., Gawande, A. A. 2011; 149 (4): 519-524

    Abstract

    Surgical care is a vital component of health care worldwide, yet there is no clinically meaningful measure of operative outcomes that could be applied globally. The Surgical Apgar Score, a simple metric derived from 3 intraoperative parameters, has been shown in U.S. academic medical centers to predict 30-day patient outcomes after operation, but has not been validated more broadly.We collected the components of the Surgical Apgar Score at the time of operation for 5,909 adult patients undergoing noncardiac operative procedures under general anesthesia at 8 hospitals in diverse international settings and evaluated the relationship between patients' scores and the incidence of inpatient postoperative morbidity and mortality, using generalized estimating equations to adjust for clustering within sites.During the first 30 days of postoperative hospitalization, 544 patients (9.2%) experienced ≥ 1 complications. Compared with patients with the median score of 7--whose complication rate was 9.1%-those with a Surgical Apgar Score <5 (n = 302) had an adjusted complication rate of 32.9% (relative risk [RR],3.6; 95% CI, 2.9-4.5), whereas those with a score of 10 (n = 238) had a 3.0% adjusted complication rate (RR, 0.3; 95% CI, 0.1-1.1). The score's c-statistic for prediction of any complication is 0.70; for death it is 0.77.The Surgical Apgar Score is easily calculated, predictive, and moderately discriminative for major complications among adults undergoing inpatient noncardiac operative procedures. Such a score could provide objective indication of relative postoperative risk for inpatients and provide a potential target for quality improvement efforts, particularly in resource-limited settings.

  • Changes in safety attitude and relationship to decreased postoperative morbidity and mortality following implementation of a checklist-based surgical safety intervention BMJ QUALITY & SAFETY Haynes, A.

K., Taylor, B., Vats, A., Gawande, A. A. 2011; 20 (1): 102-107

    Abstract

    To assess the relationship between changes in clinician attitude and changes in postoperative outcomes following a checklist-based surgical safety intervention.Pre- and post intervention survey.Eight hospitals participating in a trial of a WHO surgical safety checklist.Clinicians actively working in the designated study operating rooms at the eight hospitals. SURVEY INSTRUMENT: Modified operating-room version Safety Attitudes Questionnaire (SAQ).Change in mean safety attitude score and correlation between change in safety attitude score and change in postoperative outcomes, plus clinician opinion of checklist efficacy and usability.Clinicians in the preintervention phase (n=281) had a mean SAQ score of 3.91 (on a scale of 1 to 5, with 5 representing better safety attitude), while the postintervention group (n=257) had a mean of 4.01 (p=0.0127). The degree of improvement in mean SAQ score at each site correlated with a reduction in postoperative complication rate (r=0.7143, p=0.0381). The checklist was considered easy to use by 80.2% of respondents, while 19.8% felt that it took a long time to complete, and 78.6% felt that the programme prevented errors. Overall, 93.4% would want the checklist used if they were undergoing operation.Improvements in postoperative outcomes were associated with improved perception of teamwork and safety climate among respondents, suggesting that changes in these may be partially responsible for the effect of the checklist. Clinicians held the checklist in high regard and the overwhelming majority would want it used if they were undergoing surgery themselves.

    Abstract

    The World Health Organization's Patient Safety Programme created an initiative to improve the safety of surgery around the world. In order to accomplish this goal the programme team developed a checklist with items that could and, if at all possible, should be practised in all settings where surgery takes place. There is little guidance in the literature regarding methods for creating a medical checklist. The airline industry, however, has more than 70 years of experience in developing and using checklists. The authors of the WHO Surgical Safety Checklist drew lessons from the aviation experience to create a safety tool that supports essential clinical practice. In order to inform the methodology for development of future checklists in health care, we review how we applied lessons learned from the aviation experience in checklist development to the development of the Surgical Safety Checklist and also discuss the differences that exist between aviation and medicine that impact the use of checklists in health care.

  • Adopting A Surgical Safety Checklist Could Save Money And Improve The Quality Of Care In U.S. Hospitals HEALTH AFFAIRS Semel, M. E., Resch, S., Haynes, A. B., Funk, L. M., Bader, A., Berry, W. R., Weiser, T. G., Gawande, A. A. 2010; 29 (9): 1593-1599

    Abstract

    Use of the World Health Organization's Surgical Safety Checklist has been associated with a significant reduction in major postoperative complications after inpatient surgery. We hypothesized that implementing the checklist in the United States would generate cost savings for hospitals. We performed a decision analysis comparing implementation of the checklist to existing practice in U.S. hospitals. In a hospital with a baseline major complication rate after surgery of at least 3 percent, the checklist generates cost savings once it prevents at least five major complications. Using the checklist would both save money and improve the quality of care in hospitals throughout the United States.

  • Effect of A 19-Item Surgical Safety Checklist During Urgent Operations in A Global Patient Population ANNALS OF SURGERY Weiser, T. G., Haynes, A. B., Dziekan, G., Berry, W. R., Lipsitz, S. R., Gawande, A. A. 2010; 251 (5): 976-980

    Abstract

    To assess whether implementation of a 19-item World Health Organization (WHO) Surgical Safety Checklist in urgent surgical cases would improve compliance with basic standards of care and reduce rates of deaths and complications.Use of the WHO Surgical Safety Checklist has been shown to be associated with significant reductions in complications and deaths. Before evaluation of this safety tool, concern was raised about whether its use would be practical or beneficial during urgent surgical procedures.We prospectively collected clinical process and outcome data for 1750 consecutively enrolled patients 16 years of age or older undergoing urgent noncardiac surgery before and after introduction of the WHO Surgical Safety Checklist in 8 diverse hospitals around the world; 842 underwent urgent surgery-defined as an operation required within 24 hours of assessment to be beneficial-before introduction of the checklist and 908 after introduction of the checklist. The primary end point was the rate of complications, including death, during hospitalization up to 30 days following surgery.The complication rate was 18.4% (n=151) at baseline and 11.7% (n=102) after the checklist was introduced (P=0.0001). Death rates dropped from 3.7% to 1.4% following checklist introduction (P=0.0067). Adherence to 6 measured safety steps improved from 18.6% to 50.7% (P<0.0001).Implementation of the checklist was associated with a greater than one-third reduction in complications among adult patients undergoing urgent noncardiac surgery in a diverse group of hospitals. Use of the WHO Surgical Safety Checklist in urgent operations is feasible and should be considered.

  • Key Concepts for Estimating the Burden of Surgical Conditions and the Unmet Need for Surgical Care WORLD JOURNAL OF SURGERY Bickler, S., Ozgediz, D., Gosselin, R., Weiser, T., Spiegel, D., Hsia, R., Dunbar, P., McQueen, K., Jamison, D. 2010; 34 (3): 374-380

    Abstract

    Surgical care is emerging as a crucial issue in global public health. Methodology is needed to assess the impact of surgical care from a public health perspective.A consensus opinion of a group of surgeons, anesthesiologists, and public health experts was established regarding the methodology for estimating the burden of surgical conditions and the unmet need for surgical care.For purposes of analysis, we define surgical conditions as any disease state requiring the expertise of a surgically trained provider. Abnormalities resulting from a surgical condition or its treatment are termed surgical sequelae. Surgical care is defined as any measure that reduces the rates of physical disability or premature death associated with a surgical condition. To measure the burden of surgical conditions and unmet need for surgical care we propose using cumulative disability-adjusted life-year (DALY) curves generated from age-specific population-based data. This conceptual framework is based on the premise that surgically associated disability and death is determined by the incidence of surgical conditions and the quantity and quality of surgical care. The burden of surgical conditions is defined as the total disability and premature deaths that would occur in a population should there be no surgical care; the unmet need for surgical care is defined as the potentially treatable disability and premature deaths due to surgical conditions. Burden of surgical conditions should be expressed as DALYs and unmet need as potential DALYs avertable.Methodology is described for estimating the burden of surgical conditions and unmet need for surgical care. Using this approach it will be feasible to estimate the global burden of surgical conditions and help clarify where surgery fits among other global health priorities. These methods need to be validated using population-based data.

    Abstract

    Access to surgical services is emerging as a crucial issue in global public health. "Effective coverage" is a health metric used to evaluate essential health services in low- and middle-income countries. It measures the fraction of potential health gained that is actually realized for a given intervention by integrating the concepts of need, use, and quality.This study applies the concept of effective coverage to surgical services by considering injuries and obstetric complications as high-priority surgical conditions in low- and middle-income countries.Effective coverage for both is poor, but it is less well defined for traumatic conditions compared to obstetric conditions owing to a lack of data.More primary and secondary data are critical to measure effective coverage and to estimate the resources required to improve access to surgical services in low- and middle-income countries.
