Developing Process Maps as a Tool for a Surgical Infection Prevention Quality Improvement Initiative in Resource-Constrained Settings
JOURNAL OF THE AMERICAN COLLEGE OF SURGEONS
2018; 226 (6): 1103-+
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.

An Update on Fatalities Due to Venomous and Nonvenomous Animals in the United States (2008-2015).
Wilderness & environmental medicine
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.

Development of a Surgical Infection Surveillance Program at a Tertiary Hospital in Ethiopia: Lessons Learned from Two Surveillance Strategies.
2018; 19 (1): 25–32
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.

Sex disparities among persons receiving operative care during armed conflicts.
Armed conflict increasingly involves civilian populations, and health care needs may be immense. We hypothesized that sex disparities may exist among persons receiving operative care in conflict zones and sought to describe predictors of disparity.We performed a retrospective analysis of operative interventions performed between 2008 and 2014 at Médecins Sans Frontières Operation Center Brussels conflict projects. A Médecins Sans Frontières Operation Center Brussels conflict project was defined as a program established in response to human conflict, war, or social unrest. Intervention- and country-level variables were evaluated. For multivariate analysis, multilevel mixed-effects logistic regression was used with random-effect modeling to account for clustering and population differences in conflict zones.Between 2008 and 2014, 49,715 interventions were performed in conflict zones by Médecins Sans Frontières Operation Center Brussels. Median patient age was 24 years (range: 1-105 years), and 34,436 (69%) were men. Patient-level variables associated with decreased interventions on women included: American Society of Anesthesiologists score (P = .003), degree of urgency (P = .02), mechanism (P < .0001), and a country's predominant religion (P = .006). Men were 1.7 times more likely to have an operative intervention in a predominantly Muslim country (P = .006).Conflict is an unfortunate consequence of humanity in a world with limited resources. For most operative interventions performed in conflict zones, men were more commonly represented. Predominant religion was the greatest predictor of increased disparity between sexes, irrespective of the number of patients presenting as a result of traumatic injury. It is critical to understand what factors may underlie this disparity to ensure equitable and appropriate care for all patients in an already tragic situation.

Impact of Surgical Lighting on Intraoperative Safety in Low-Resource Settings: A Cross-Sectional Survey of Surgical Providers.
World journal of surgery
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.

Surgical Instrument Reprocessing in Resource-Constrained Countries: A Scoping Review of Existing Methods, Policies, and Barriers.
2018; 19 (6): 593–602
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.

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
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.

Self-reported Determinants of Access to Surgical Care in 3 Developing Countries
2016; 151 (3): 257-263
Surgical care is recognized as a growing component of global public health.To assess self-reported barriers to access of surgical care in Sierra Leone, Rwanda, and Nepal using the validated Surgeons OverSeas Assessment of Surgical Need tool.Data for this cross-sectional, cluster-based population survey were collected from households in Rwanda (October 2011), Sierra Leone (January 2012), and Nepal (May and June 2014) using the Surgeons OverSeas Assessment of Surgical Need tool.Basic demographic information, cost and mode of transportation to health care facilities, and barriers to access to surgical care of persons dying within the past year were analyzed.A total of 4822 households were surveyed in Nepal, Rwanda, and Sierra Leone. Primary health care facilities were commonly reached rapidly by foot (>70%), transportation to secondary facilities differed by country, and public transportation was ubiquitously required for access to a tertiary care facility (46%-82% of respondents). Reasons for not seeking surgical care when needed included no money for health care (Sierra Leone: n = 103; 55%), a person dying before health care could be arranged (all countries: 32%-43%), no health care facility available (Nepal: n = 11; 42%), and a lack of trust in health care (Rwanda: n = 6; 26%).Self-reported determinants of access to surgical care vary widely among Sierra Leone, Rwanda, and Nepal, although commonalities exist. Understanding the epidemiology of barriers to surgical care is essential to effectively provide surgical service as a public health commodity in developing countries.

Twelve Tips for Improving the General Surgery Resident Night Float Experience.
WMJ : official publication of the State Medical Society of Wisconsin
2015; 114 (3): 110-115
Restriction of resident duty hours has resulted in the implementation of night float systems in surgical and medical programs. Many papers have examined the benefits and structure of night float, but few have addressed patient safety issues, quality patient care, and the impact on the residency education system. The objective of this review is to provide practical tips to optimize the night float experience for resident training while continuing to emphasize patient care. The tips provided are based on the experiences and reflections of residents, supervising staff, group discussions, and the available literature in a hospital-based general surgery residency program. Utilizing these resources, we concluded that the night float system addresses resident work hour restrictions; however, it ultimately creates new issues. Adaptations will help achieve a balance between resident education and patient safety.

Fatalities From Venomous and Nonvenomous Animals in the United States (1999-2007)
WILDERNESS & ENVIRONMENTAL MEDICINE
2012; 23 (2): 146-152
To review recent (1999-2007) US mortality data from deaths caused by nonvenomous and venomous animals and compare recent data with historic data.The CDC WONDER Database was queried to return all animal-related fatalities between 1999 and 2007. Rates for animal-related fatalities were calculated using the estimated 2003 US population. Inclusion criteria included all mortalities that were a consequence of bite, contact, attack, or envenomation (ICD-10 codes W53-W59 and X20-X29).There were 1802 animal-related fatalities with the majority coming from nonvenomous animals (60.4%). The largest percentage (36.4%) of animal-related fatalities was attributable to "other mammals," which is largely composed of farm animals. Deaths attributable to Hymenoptera (hornets, wasps, and bees) have increased during the past 60 years in the United States and now account for more than 79 fatalities per year and 28.2% of the total animal-related fatalities from 1999 to 2007. Dog-related fatalities have increased in the United States, accounting for approximately 28 fatalities per year and 13.9% of the total animal-related fatalities.Prevention measures aimed at minimizing injury from animals should be directed at certain high-risk groups such as farmworkers, agricultural workers, and parents of children with dogs.
