MRI for Scaphoid Nonunion: Utilization Rates, Factors Associated with Utilization, and Subsequent Vascularized Bone Graft Use.
The Journal of hand surgery
2024
Abstract
The use of magnetic resonance imaging (MRI) for evaluation of scaphoid nonunion may be an example of low-value imaging for the treatment of scaphoid nonunion. The purpose of this study was to investigate variation in MRI use for scaphoid nonunion, the association of MRI with a vascularized bone graft (VBG) and to develop consensus on MRI use for scaphoid nonunion.We identified patients >18 years of age who underwent scaphoid nonunion surgery between 2010 and 2019 using a claims database. Patients who had, and did not have, an MRI within 90 days prior to their diagnosis of scaphoid nonunion were included and a multivariable analysis was performed to evaluate variation in MRI and VBG use. Subsequently, a literature review was performed, and a preliminary consensus statement was developed pertaining to the routine use of MRI for scaphoid nonunion. A consortium of nine hand surgeons evaluated the importance, feasibility, usability, and scientific acceptability of the statement through a modified RAND Coroporation/University of California, Los Angeles Delphi. Panelists evaluated the statement in two voting rounds with an intervening face-to-face discussion.We identified 1,324 eligible patients with surgical repair of a scaphoid nonunion. Two hundred and sixty-three (19.9%) underwent an MRI within 90 days prior to surgery. Differences in age, insurance type, and comorbidity burden existed between patients who received MRI and those who did not. The MRI cohort was more likely to receive VBG (10.6%) compared to those without an MRI (4.7%). Panelists agreed on the voting domains of the consensus statement and therefore the statement, "There is no benefit of routine MRI/MRA in the treatment of scaphoid nonunion with or without presumed avascular necrosis," was considered valid.MRI use within 90 days of surgical repair of scaphoid nonunion varies, is associated with greater rates of VBG use, and may represent low-value imaging given the lack of sufficient evidence on this topic.As MRI use for scaphoid nonunion varies and may represent low-value imaging, a validated consensus statement may help guide the evaluation of patients with scaphoid nonunion.

Claims Database Research in Hand Surgery: From Data to Bedside.
The Journal of hand surgery
2024
Abstract
The widespread availability of administrative claims data has unlocked opportunities to answer challenging clinical questions in hand surgery, overcoming the limitations of traditional data sets. Researchers are taking advantage of claims data sets to obtain samples from broader segments of the population and achieve statistical power that was previously unattainable. Therefore, a basic understanding of claims database research is quickly becoming an invaluable tool in the surgeon's toolkit, enabling the performance of ground-breaking research and the critical evaluation of data-driven results to inform clinical practice. We provide an overview of methodological approaches to claims data analysis for hand surgery and a roadmap for analyzing and interpreting these studies in clinical practice.

Utilization of Surgical Fixation for Distal Radius Fractures in the United States: A Population-Based Cohort Study.
The Journal of hand surgery
2024
Abstract
In contrast to younger adult populations, clinical practice guidelines state that there is no difference in long-term functional outcomes in surgically versus nonoperatively treated distal radius fractures in patients ≥65 years old. In this study, we asked the following questions: (1) has treatment for distal radius fractures in younger and older adult populations changed over time? (2) What patient and surgeon factors are associated with treatment trends?Using a national administrative claims database, we identified patients aged ≥18 years with isolated, closed distal radius fractures, subdivided by age (18-64 years, ≥65 years old). We characterized the proportion of patients who underwent open reduction and internal fixation (ORIF) over time. We stratified our analysis by surgeon subspecialty, region, and mean area income. Changes in ORIF utilization over time were evaluated using linear regression models.The proportion of distal radius ORIF, including in patients aged ≥65 years, increased from 10.4% in 2012 to 15.1% in 2020. Of the ORIF procedures performed, hand surgeons accounted for an increasing proportion over time, with a corresponding decrease in those performed by general orthopedic surgeons. The proportion of ORIF increased over time in all US regions, with the largest rate of increase in the Midwest for patients aged ≥65 years and Northeast for patients aged 18-64 years. Patients living in areas with mean family income ≥$65,000 were more likely to undergo ORIF.The proportion of distal radius ORIF including in older adult populations is increasing in all US regions, and an increasing proportion is performed by hand surgeons.Further analysis of the drivers of these trends is warranted, given the rising incidence of surgical treatment in older patients, which could reflect evolving patient activity demands and suggest a need to further evaluate conventional treatment algorithms based on age.

Goal Concordant Care: A Cross-Sectional Study Evaluating Correlates of Concordant Care and Association With Satisfaction and Outcomes.
Hand (New York, N.Y.)
2024: 15589447241279458
Abstract
BACKGROUND: The concordance between patient and physician goals has been associated with improved outcomes in many chronic diseases. The purpose of this study was to evaluate the association between goal concordant care, patient satisfaction, and patient experience and to analyze factors associated with goal concordant care in hand and upper extremity surgery.METHODS: New patients who were 18 years or older were invited to participate. Goal concordant care was defined as the patient's previsit treatment goal matching the primary treatment received. The chi2 tests were used to evaluate the association between goal concordant care and patient satisfaction and patient experience. We conducted univariable logistic regression to evaluate variables for their association with concordance and multivariable logistic regression for variables that were significantly associated in the initial analyses to evaluate their aggregate influence on concordance.RESULTS: In total, 169 patients enrolled. The rate of goal concordant care was 62%; concordance was not associated with patient satisfaction or experience. Age, sex, English proficiency, health literacy, education level, employment and relationship status, pain self-efficacy, symptom duration, functional disability, and patient-centered decision-making were not associated with concordant care. Patients with annual income less than $50,000 had significantly higher odds of goal discordant care.CONCLUSION: Patients with lower income had more than 3 times the odds of receiving discordant care. However, discordant care was not associated with patient satisfaction or experience. Further studies on other pertinent outcomes are needed in orthopedic surgery (eg, treatment adherence). Known care disparities based on socioeconomic status may be mediated through care discordance and should be investigated.

Disparities Exist in Knowledge of Hip Fracture Compared With Stroke and Myocardial Infarction
ORTHOPEDICS
2024: 1-7
Abstract
This study sought to answer the following questions: (1) Are there differences in knowledge on time to treatment (TTT) between stroke, myocardial infarction (MI), and hip fractures in the general population? (2) Are there differences in condition-specific knowledge across these conditions? (3) Are there underlying demographic factors that may contribute to differences in hip fracture-specific knowledge?This was a cross-sectional cohort analysis. Participants were acquired using an online survey distribution platform, Amazon Mechanical Turk (MTurk). Individuals older than 18 years with English fluency and literacy were included. A total of 913 participants who completed a survey with questions on TTT knowledge, condition-specific knowledge, history of hip fracture, and demographics were recruited.On comparing TTT knowledge, the MI mean score was 36.92% higher than that of hip fractures (P<.0001). On comparing condition-specific knowledge, the MI-specific mean score was 8.24% higher than that of hip fractures (P<.0001). Hip fracture knowledge was associated with demographic factors. Asian and Black participants and participants with Medicaid or Medicare as their primary insurance type were associated with significantly lower hip fracture knowledge.Hip fracture knowledge was significantly lower than MI knowledge in the study population. Just as professional societies have invested resources in public education campaigns on the importance of TTT for stroke and MI, public education campaigns on the importance of TTT for hip fractures may support earlier TTT for populations vulnerable to delays (Asian and Black).

Current Use of Patient-Reported Outcome Measures Ignores Functional Demand.
The Journal of the American Academy of Orthopaedic Surgeons
2024
Abstract
Patient-reported outcome measures (PROMs) are used in orthopaedic surgery to measure aspects of musculoskeletal function that are important to patients, such as disability and pain. However, current assessments of function using PROMs do not necessarily consider a patient's functional demands in detail. A patient's functional demands could serve as a confounder to their perception of their functional ability. Hence, functional demands may need to be adjusted for when PROMs are used to measure musculoskeletal function.We conducted a cross-sectional study in which new orthopaedic patients completed a questionnaire regarding demographics, function [Patient-Reported Outcomes Measurement Information System], functional demand (Tegner Activity Level Scale), pain self-efficacy, and symptoms of depression. 169 eligible patients with diverse orthopaedic conditions were enrolled in the study from an orthopaedic clinic, and 19 were excluded for incomplete questionnaires.The mean Patient-Reported Outcomes Measurement Information System score was 36.5 ± 9.1, and the mean Tegner score was 2.6 ± 2.0. In the multivariable regression model, patient-reported function was significantly associated with functional demand (β = 0.17, P < 0.001). Significant associations were observed for pain self-efficacy (β = 0.15, P < 0.001), acuity (β = -0.10, P = 0.004), and age 80 years or older (β = -0.16, P = 0.004). No notable association was observed with depression or age 65 to 79 years.Higher patient-reported physical function is associated with higher levels of functional demand when controlling for psychosocial factors, acuity, and age. Because of its confounding effect on measuring physical function, functional demand should be assessed and included in models using PROMs before and after surgery. For example, payment models using improvements in PROMs, such as the short form of the Hip dysfunction and Osteoarthritis Outcome Score and the Knee injury and Osteoarthritis Outcome Score after joint arthroplasty, should include functional demand in the model when assessing quality of care.Level II.

The Association Between Social Determinants of Health and Distal Radius Fracture Outcomes.
The Journal of hand surgery
2024
Abstract
The purpose of this study was to determine if adverse social determinants of health (SDOH) are associated with differential complication rates following surgical fixation of distal radius fractures and assess which SDOH domain (economic, educational, social, health care, or environmental) is most associated with postoperative complications.Using a national administrative claims database, we conducted a retrospective cohort analysis of patients undergoing open treatment for an isolated distal radius fracture between 2010 and 2020. Patients were stratified based on the presence/absence of at least one SDOH code and propensity score matched to create two cohorts balanced by age, sex (male or female), insurance type, and comorbidities. Social determinants of health examined included economic, educational, social, health care, and environmental factors. Multivariable logistic regression analyses were performed to assess the isolated effect of SDOH on 90-day and 1-year complication rates.After propensity matching, 57,025 patients in the adverse SDOH cohort and 57,025 patients in the control cohort were included. Patients facing an adverse SDOH were significantly more likely to experience 90-day complications, including emergency department visits (Odds ratio (OR): 3.18 [95% confidence interval (CI): 3.07-3.29]), infection (OR: 2.37 [95% CI: 2.12-2.66]), wound dehiscence (OR: 2.06 [95% CI: 1.72-2.49]), and 1-year complications, including complex regional pain syndrome (OR: 1.35 [95% CI: 1.15-1.58]), malunion/nonunion (OR: 1.18 [95% CI: 1.08-1.29]), and hardware removal (OR: 1.13 [95% CI: 1.07-1.20]). Additionally, patients facing an adverse SDOH had a significantly increased risk of 90-day complications, regardless of fracture severity, and patients with economic and social challenges had the highest odds of both 90-day and 1-year postoperative complications.Social determinants of health are associated with increased complications following distal radius fracture fixation, even when controlling for demographic and clinical factors. We recommend routine screening for adverse SDOH and inclusion of SDOH data into health records to not only inform quality improvement initiatives and risk adjustment for outcome-based quality measurements but also to allow providers to begin to discuss and address such barriers during the perioperative period.Prognosis II.

Site of Service Disparities Exist for Total Joint Arthroplasty
ORTHOPEDICS
2024; 47 (3): 179-184
Abstract
The rate of outpatient total joint arthroplasty procedures, including those performed at ambulatory surgical centers (ASCs) and hospital outpatient departments, is increasing. The purpose of this study was to analyze if type of insurance is associated with site of service (in-patient vs outpatient) for total joint arthroplasty and adverse outcomes.We identified patients undergoing unicompartmental knee arthroplasty (UKA), total knee arthroplasty (TKA), or total hip arthroplasty (THA) using Current Procedural Terminology codes in a national administrative claims database. Eligible patients were stratified by type of insurance (Medicaid, Medicare, private). The primary outcome was site of service. Secondary outcomes included general complications, procedural complications, and revision procedures. We evaluated the associations using adjusted multivariable logistic regression models.We identified 951,568 patients for analysis; 46,703 (4.9%) patients underwent UKA, 607,221 (63.8%) underwent TKA, and 297,644 (31.3%) underwent THA. Overall, 9.6% of procedures were outpatient. Patients with Medicaid were less likely than privately insured patients to receive outpatient UKA or THA (UKA: odds ratio [OR], 0.729 [95% CI, 0.640-0.829]; THA: OR, 0.625 [95% CI, 0.557-0.702]) but more likely than patients with Medicare to receive outpatient TKA or THA (TKA: OR, 1.391 [95% CI, 1.315-1.472]; THA: OR, 1.327 [95% CI, 1.166-1.506]). Patients with Medicaid were more likely to experience complications and revision procedures.Differences in site of service and complication rates following hip and knee arthroplasty exist based on type of insurance, suggesting a disparity in care. Further exploration of drivers of this disparity is warranted and can inform interventions (eg, progressive value-based payments) to support equity in orthopedic services.

Acute Total Hip Arthroplasty Following Acetabular Fracture is Associated with a High Risk of Revision, Dislocation, and Periprosthetic Fracture.
The Journal of arthroplasty
2024
Abstract
BACKGROUND: The aim of this study was to compare outcomes between acute, subacute, and delayed arthroplasty for acetabular fractures occurring within one week, from one week to six months, or longer than six months before the index total hip arthroplasty (THA), versus THA without a history of acetabular fracture as a control.METHODS: We analyzed the records of patients undergoing primary THA who were enrolled in a national database for at least two years before and after the index procedure. Patients who had an initial diagnostic code for acetabular fracture occurring less than one week, from one week to six months, or at least more than six months before the THA were classified as acute THA (aTHA), subacute (saTHA), or delayed (dTHA), respectively. The control group was patients undergoing THA who did not have a history of acetabular fracture. There were 430,349 control primary THAs, 462 aTHAs, 675 saTHAs, and 1,162 dTHAs.RESULTS: After adjusting for age, sex, region, and comorbidities, patients who had an aTHA and saTHA experienced statistically significant increased odds of revision, dislocation, and periprosthetic fracture compared to primary THA without a history of acetabular fracture. Similarly, dTHA was associated with increased odds of revision, dislocation, and periprosthetic fractures compared to primary THA. In the multivariate analysis, aTHA had statistically significant higher rates of dislocation when compared to dTHA.CONCLUSION: Patients who had a history of acetabular fractures undergoing aTHA, saTHA, or dTHA have significantly increased rates of revision, periprosthetic fracture, and dislocation compared to primary THA in those who did not have a history of acetabular fractures.

Cost-Effectiveness Analysis of Early versus Late Debridement of Superficial Triangular Fibrocartilage Complex Tears.
Journal of hand and microsurgery
2024; 16 (1): 100009
Abstract
While initial nonoperative management is the conventional approach for superficial triangular fibrocartilage complex (TFCC) tears, a substantial portion of these cases go on to require surgery, and the optimal duration of nonoperative treatment is unknown. In this study, we evaluate the cost-effectiveness of early versus late arthroscopic debridement for the treatment of superficial TFCC tears without distal radioulnar joint (DRUJ) instability.We created a decision tree to compare the following strategies from a healthcare payer perspective: immediate arthroscopic debridement versus immobilization for 4 or 6 weeks with late debridement as needed. Costs were obtained from the Centers for Medicaid and Medicare Services and a national administrative claims database. Probabilities and health-related quality-of-life measures were obtained from published sources. We conducted sensitivity analyses on model inputs, including a probabilistic sensitivity analysis consisting of 10,000 Monte Carlo simulations.Immobilization for 6 weeks while reserving arthroscopic debridement for refractory cases was both the least costly and most effective strategy. Immediate arthroscopic debridement became cost-effective when success rates of immobilization for 4 or 6 weeks were less than 7.7 or 10.5%, respectively. Our probabilistic sensitivity analysis showed that immobilization for 6 weeks was preferred 97.6% of the time, and immobilization for 4 weeks was preferred 2.4% of the time.Although various early and late debridement strategies can be used to treat superficial TFCC tears without DRUJ instability, immobilization for 6 weeks while reserving arthroscopic debridement for refractory cases is the optimal strategy from a cost-effectiveness standpoint.

Medicaid Insurance is Associated With Decreased MRI Use for Ankle Sprains Compared With Private Insurance: A Retrospective Database Analysis.
Clinical orthopaedics and related research
2023
Abstract
BACKGROUND: Advanced imaging modalities are expensive, and access to advanced imaging services may vary by socioeconomic factors, creating the potential for unwarranted variations in care. Ankle sprains are a common injury for which variations in MRI use can occur, both via underuse of indicated MRIs (appropriate use) and overuse of nonindicated MRIs (inappropriate use). High-value, equitable healthcare would decrease inappropriate use and increase appropriate use of MRI for this common injury. It is unknown whether socioeconomic factors are associated with underuse of indicated MRIs and overuse of nonindicated MRIs for ankle sprains.QUESTIONS/PURPOSES: Using ankle sprains as a paradigm injury, given their high population incidence, we asked: (1) Does MRI use for ankle sprains vary by insurance type? (2) After controlling for relevant confounding variables, did patients who received an MRI have higher odds of undergoing ankle surgery?METHODS: Between 2011 and 2019, a total of 6,710,223 patients were entered into the PearlDiver Mariner Patient Records Database with a diagnosis of ankle sprain. We considered patients with continuous enrollment in the database for at least 1 year before and 2 years after the diagnosis as potentially eligible. Based on that, 68% (4,567,106) were eligible; a further 20% (1,372,478) were excluded because of age younger than 18 years, age at least 65 years with Medicaid insurance, or age < 65 years with Medicare insurance. Another 0.1% (9169) had incomplete data, leaving 47% (3,185,459) for analysis here. Patients with Medicaid insurance differed from patients with Medicare Advantage or private insurance with respect to age, gender, region, and comorbidity burden. The primary outcome was ankle MRI occurring within 12 months after diagnosis. The use of ankle surgery after MRI in each cohort was measured as a secondary outcome. We used multivariable logistic regression models to evaluate the association between insurance type and MRI use while adjusting for age, gender, region, and comorbidity burden. Separate multivariable regression models were created to evaluate the association between receiving an MRI and subsequent ankle surgery for each insurance type, adjusting for age, gender, region, and comorbidity burden. Within 12 months of an ankle sprain diagnosis, 1% (3522 of 339,457) of patients with Medicaid, 2% (44,793 of 2,627,288) of patients with private insurance, and 1% (1660 of 218,714) of patients with Medicare Advantage received an MRI.RESULTS: After controlling for age, gender, region, and comorbidity burden, patients with Medicaid had lower odds of receiving an MRI within 12 months after ankle sprain diagnosis than patients with private insurance (odds ratio 0.60 [95% confidence interval 0.57 to 0.62]; p < 0.001). Patients with Medicaid who received an MRI had higher adjusted odds of undergoing subsequent ankle surgery (OR 23 [95% CI 21 to 26]; p < 0.001) than patients with private insurance (OR 12.7 [95% CI 12 to 13]; p < 0.001).CONCLUSION: Although absolute MRI use was generally low, there was substantial relative variation by insurance type. Given the high incidence of ankle sprains in the general population, these relative differences can translate to tens of thousands of MRIs. Further studies are needed to evaluate the reasons for decreased appropriate MRI use in patients with Medicaid and overuse of MRI in patients with private insurance. The establishment of clinical practice guidelines by orthopaedic professional societies and more stringent gatekeeping for MRI use by health insurers could reduce unwarranted variations in MRI use.LEVEL OF EVIDENCE: Level III, prognostic study.

Variations in Treatment and Costs for Distal Radius Fractures in Patients Over 55 Years of Age: A Population-Based Study.
Journal of hand and microsurgery
2023; 15 (5): 351-357
Abstract
Objective To evaluate the rate of surgery for symptomatic malunion after nonoperatively treated distal radius fractures in patients aged 55 and above, and to secondarily report differences in demographics, geographical variation, and utilization costs of patients requiring subsequent malunion correction. Methods We identified patients aged 55 and above who underwent nonoperative treatment for a distal radius fracture between 2007 and 2016 using the IBM MarketScan database. In the nonoperative cohort, we identified patients who underwent malunion correction between 3 months and 1 year after distal radius fracture. The primary outcome was rate of malunion correction. Multivariable logistic regression controlling for sex, region, and Elixhauser Comorbidity Index (ECI) was used. We also report patient demographics, geographical variation, and utilization cost. Results The rate of subsequent malunion surgery after nonoperative treatment was 0.58%. The cohort undergoing malunion surgery was younger and had a lower ECI. For every 1-year increase in age, there was a 6.4% decrease in odds of undergoing surgery for malunion, controlling for sex, region, and ECI (odds ratio = 0.94 [0.93-0.95]; p < 0.01). The southern United States had the highest percentage of patients initially managed operatively (30.7%), the Northeast had the lowest (22.0%). Patients who required a malunion procedure incurred higher costs compared with patients who did not ($7,272 ± 8,090 vs. $2,209 ± 5,940; p < 0.01). Conclusion The rate of surgery for symptomatic malunion after initial nonoperative treatment for distal radius fractures in patients aged 55 and above is low. As younger and healthier patients are more likely to undergo malunion correction with higher associated costs, surgeons may consider offering this cohort surgical treatment initially.

Strategies for Perioperative Optimization in Upper Extremity Fracture Care.
Hand clinics
2023; 39 (4): 617-625
Abstract
Perioperative optimization in upper extremity fracture care must balance the need for timely treatment with the benefits of medical optimization. Care pathways directed at optimizing glycemic control, chronic anticoagulation, smoking history, nutrition, and frailty can reduce surgical risk in upper extremity fracture care. The development of multidisciplinary approaches that tie risk modification with risk stratification is needed.

Is There Variation in Time to and Type of Treatment for Hip Osteoarthritis Based on Insurance?
The Journal of arthroplasty
2023
Abstract
Disparities in access to care based on insurance type exist for total hip arthroplasty (THA), but it is unclear if these lead to longer times to surgery. We evaluated whether rates of THA versus non-operative interventions (NOI) and time to THA from initial hip osteoarthritis (OA) diagnosis vary by insurance type.Using a national claims database, patients who had hip OA undergoing THA or NOI from 2011 to 2019 were identified and divided by insurance type: Medicaid managed care; Medicare Advantage; and commercial insurance. The primary outcome was THA incidence within 3 years after hip OA diagnosis. Multivariable logistic regression models were created to assess the association between THA and insurance type, adjusting for age, sex, region, and comorbidities.Medicaid patients had lower rates of THA within 3 years of initial diagnosis (7.4 vs. 10.9 or 12.0%, respectively; P<0.0001) and had longer times to surgery (297 vs. 215 or 261 days, respectively; P<0.0001) compared to Medicare Advantage and commercially insured patients. In multivariable analyses, Medicaid patients were also less likely to receive THA (Odds Ratio (OR) = 0.62 [95% Confidence Intervals (CI): 0.60-0.64] vs. Medicare Advantage, OR = 0.63 [95% CI: 0.61-0.64] vs. commercial) or NOI (OR = 0.92 [95% CI: 0.91-0.94] vs. Medicare Advantage, OR = 0.81 [95% CI: 0.79-0.82] vs. commercial).Medicaid patients experienced lower rates of and longer times to THA than Medicare Advantage or commercially insured patients. Further investigation into the causes of these disparities, such as patient costs or access barriers, is necessary to ensure equitable care.

Is Outpatient Spine Surgery Associated with New, Persistent Opioid Use in Opioid-Naïve Patients? A Retrospective National Claims Database Analysis.
The spine journal : official journal of the North American Spine Society
2023
Abstract
Although spine procedures have historically been performed inpatient, there has been a recent shift to the outpatient setting for selected cases due to increased patient satisfaction and reduced cost. Effective postoperative pain management while limiting over-prescribing of opioids, which may lead to persistent opioid use, is critical to performing spine surgery in the outpatient setting.To assess if there is an increased risk for new, persistent opioid use between inpatient and outpatient spine procedures.Retrospective analysis using national administrative claims database.390,049 opioid-naïve patients with a perioperative opioid prescription who underwent an inpatient or outpatient spine surgery.Patients with perioperative opioid prescriptions who filled ≥ 1 opioid prescription between 90- and 180-days following surgery were defined as new, persistent opioid users.We utilized a claims database to identify opioid-naïve patients who underwent lumbar or cervical fusion, total disc arthroplasty, or decompression procedures. We constructed a multivariable logistic regression to evaluate the association between inpatient versus outpatient surgery and the development of new, persistent opioid use while adjusting for several patient factors.19,205 (11.7%) inpatient and 18,546 (8.2%) outpatient patients developed new, persistent opioid use. Outpatient lumbar and cervical spine surgery patients were significantly less likely to develop new, persistent opioid use following surgery compared to inpatient spine surgery patients (OR = 0.71 [95% confidence interval (CI): 0.69, 0.73], p < 0.001). Average morphine milligram equivalents (MMEs) (inpatient = 1,476 MME +/- 22.7, outpatient = 1,072 MME +/- 18.5, p < 0.001) and average MMEs per day (inpatient = 91.6 MME +/- 0.32, outpatient = 77.7 MME +/- 0.28, p < 0.001) were lower in the outpatient cohort compared to the inpatient.Our results support the shift from inpatient to outpatient spine procedures, as outpatient procedures were not associated with an increased risk for new, persistent opioid use. As more patients become candidates for outpatient spine surgery, predictors of new, persistent opioid use should be considered during risk stratification.Level III Prognostic Study.We utilized a national administrative claims database to identify opioid-naïve patients who underwent common spine procedures. Outpatient lumbar and cervical spine surgery patients were significantly less likely to be new, persistent opioid users following surgery compared to inpatient spine surgery patients. Our results support the shift to outpatient spine procedures.

The Use and Downstream Associations of Magnetic Resonance Imaging for Lateral Epicondylitis.
The Journal of hand surgery

Abstract
Low-value imaging is associated with wasteful health care spending and patient harm. The routine use of magnetic resonance imaging (MRI) for the work-up of lateral epicondylitis is an example of low-value imaging. As such, our aim was to investigate the use of MRIs ordered for lateral epicondylitis, the characteristics of those undergoing an MRI, and the downstream associations of MRI with other care.We identified patients aged ≥18 years with a diagnosis of lateral epicondylitis between 2010 and 2019 using a Humana claims database. We identified patients with a Current Procedural Terminology code corresponding to an elbow MRI. We analyzed the use and downstream treatment cascades in those undergoing MRI. Multivariable logistic regression models were used to assess the odds of undergoing an MRI, adjusting for age, sex, insurance type, and comorbidity index. Separate multivariable logistic regression analyses were used to determine the association between undergoing an MRI and the incidence of secondary outcomes (eg, receiving surgery).A total of 624,102 patients met the inclusion criteria. Of 8,209 (1.3%) patients undergoing MRI, 3,584 (44%) underwent it within 90 days after diagnosis. There was notable regional variation in MRI use. The MRIs were ordered most frequently by primary care specialties and for younger, female, commercially insured, and patients with more comorbidities. Performance of an MRI was associated with an increase in downstream treatments, including surgery (odds ratio [OR], 9.58 [9.12-10.07]), injection (OR, 2.90 [2.77-3.04]), therapy (OR, 1.81 [1.72-1.91]), and cost ($134 per patient).Although there is variation in the use of MRI for lateral epicondylitis and its use is associated with downstream effects, the routine use of MRI for the diagnosis of lateral epicondylitis is low.The routine use of MRI for lateral epicondylitis is low. Understanding interventions to minimize such low-value care in lateral epicondylitis can be used to inform improvement efforts to minimize low-value care for other conditions.

Disparities in Treatment of Closed Distal Radius Fractures in Patients Aged 18-64 Years and ≥65 Years by Insurance Type.
The Journal of hand surgery
2023
Abstract
Type of and time to definitive treatment for distal radius fractures can influence the outcomes. The impact of social determinants of health (eg, insurance type) on distal radius fracture care remains unknown despite having health equity implications. Thus, we evaluate the association between insurance type and rate of surgery, the time to surgery, and the complication rate for distal radius fractures.We conducted a retrospective cohort study using the PearlDiver Database. We identified adults with closed distal radius fractures. Patients were divided into subgroups by age (18-64 years, 65+ years) and further stratified on the basis of the insurance type (Medicare Advantage, Medicaid-managed care, and commercial). The primary outcome was the rate of surgical fixation. Secondary outcomes included the time to surgery and 12-month complication rates. Logistic regression modeling was used to calculate the odds ratios for each outcome, adjusting for age, sex, geographic region, and comorbidities.In patients aged ≥65 years, a lower proportion of Medicaid patients underwent surgery within 21 days of diagnosis compared with Medicare or commercially insured patients (12.1% vs 15.9% or 17.5%, respectively). Complication rates did not differ between Medicaid and other insurance types. In patients aged <65 years, fewer Medicaid patients underwent surgery compared with commercially insured patients (16.2% vs 21.1%). However, in this younger group, Medicaid patients had higher adjusted odds of malunion/nonunion (adjusted odds ratio [aOR] = 1.39 [95% CI, 1.31-1.47]) and subsequent repair (aOR = 1.38 [95% CI, 1.25-1.53]).Although older Medicaid patients experienced lower surgical rates, this may not lead to differential clinical outcomes. However, Medicaid patients aged <65 years experienced lower surgical rates that correlated with the increased rates of malunion or nonunion.In younger patients with a closed distal radius fracture and Medicaid insurance, system and patient-directed efforts should be considered to address delayed time to surgery and a higher odds for malunion/nonunion.

Is Hand Surgery in the Procedure Room Setting Associated with Increased Surgical Site Infection? A Cohort Study of 2,717 Patients in the Veterans Affairs Population.
The Journal of hand surgery
2023
Abstract
Procedure rooms (PRs) are increasingly used for hand surgeries, but few studies have directly compared surgical site infection (SSI) rates between the PR and operating room. We tested the hypothesis that procedure setting is not associated with an increased SSI incidence in the VA population.We identified carpal tunnel, trigger finger, and first dorsal compartment releases performed at our VA institution from 1999 to 2021 of which 717 were performed in the main operating room and 2,000 were performed in the PR. The incidence of SSI, defined as signs of wound infection within 60 days of the index procedure, which was treated with oral antibiotics, intravenous antibiotics, and/or operating room irrigation and debridement, was compared. We constructed a multivariable logistic regression analysis to assess the association between procedure setting and SSI incidence, adjusting for age, sex, procedure type, and comorbidities.Surgical site infection incidence was 55/2,000 (2.8%) in the PR cohort and 20/717 (2.8%) in the operating room cohort. In the PR cohort, five (0.3%) cases required hospitalization for intravenous antibiotics of which two (0.1%) cases required operating room irrigation and debridement. In the operating room cohort, two (0.3%) cases required hospitalization for intravenous antibiotics of which one (0.1%) case required operating room irrigation and debridement. All other SSIs were treated with oral antibiotics alone. The procedure setting was not independently associated with SSI (adjusted odds ratio, 0.84 [95% confidence interval, 0.49, 1.48]). The only risk factor for SSI was trigger finger release (odds ratio, 2.13 [95% confidence interval, 1.32, 3.48] compared with carpal tunnel release), which was independent of setting.Minor hand surgeries can be performed safely in the PR without an increased rate of SSI.Prognostic II.

What Program Characteristics Are Associated with Resident Racial Diversity in Orthopaedic Surgery? An Analysis of Association of American Medical Colleges Data.
JB & JS open access
2023; 8 (1)
Abstract
In orthopaedic surgery, there are fewer Black or African American (4%) and Hispanic or Latino (4%) residents compared with general surgery, internal medicine, family medicine, and pediatrics (5%-7% Black residents and 7%-9% Hispanic/Latino residents, respectively). There are also fewer underrepresented in medicine minority (URiM) faculty in orthopaedic surgery (6.1%) compared with general surgery (8.9%), otolaryngology (7.8%), internal medicine (9.7%), and obstetrics and gynecology (15.6%). Identifying program characteristics that are associated with the percentage of URiM residents could reveal strategies for improving diversity.Methods: Using Association of American Medical Colleges orthopaedic resident and faculty race/ethnicity data from 2007 to 2016, we analyzed the racial diversity of 166 of 207 residency programs. The primary outcome was program racial diversity, measured as the percentage of URiM residents per program. The top quartile of programs was compared with the other quartiles. Characteristics analyzed included percentage of URiM faculty, affiliation with a university/top 40 medical school/top 40 orthopaedic hospital, geographic region, city type, and city size. We used a multivariable linear regression model to evaluate program characteristics associated with diversity and a linear mixed-effects model with program-specific random effects to evaluate time trends.Results: The mean percentage of URiM residents per program was 9.3% (SD = 10.5%). In the top quartile of programs, URiM residents composed 20.7% ± 2.5% of the program compared with 5.8% ± 0.3% in other quartiles (p < 0.001). After adjusting for program and faculty size, the only factor associated with the number of URiM residents per program was the number of URiM faculty. For every 5 additional URiM faculty members, there was an associated increase in the number of URiM residents per program by 3.6 (95% confidence interval [CI]: 2.3-5.0). There was a small but statistically significant annual increase in the percentage of URiM residents per program of 0.207 (95% CI: 0.112-0.302) percentage points during the study period.Conclusion: URiM representation remains low among orthopaedic residents. Efforts to increase the URiM faculty base represent a potential strategy for programs to increase URiM representation among residents by attracting more diverse applicants.

Medicaid Insurance is Associated with Treatment Disparities for Proximal Humerus Fractures in a National Database Analysis.
Journal of shoulder and elbow surgery
2022
Abstract
BACKGROUND: Proximal humerus fractures (PHFs) are the third most common type of fragility fracture in the elderly and are increasing in incidence. Disparities in treatment type, time to surgery (TTS), and complications based upon insurance type have been identified for other orthopedic conditions. Given the incidence and burden of PHFs, we sought to evaluate if insurance type was associated with treatment received, TTS, and complications in the treatment of PHFs.METHODS: We used PearlDiver, a national administrative claims database that consists of 122 million patient records. Patients diagnosed with an isolated PHF between 2010-2019 were identified by ICD-9/10 diagnostic codes and stratified by insurance type (Medicaid, private, or Medicare). Outcomes evaluated were rate of surgery within 3 months of diagnosis with open reduction and internal fixation, hemiarthroplasty, or reverse shoulder arthroplasty; average TTS; 90-day readmissions and medical postoperative complications (deep vein thrombosis, urinary tract infection, pneumonia, sepsis, acute respiratory failure, cerebrovascular event, and acute renal failure); and 1-year surgical postoperative complications (stiffness, non-infectious wound complications, dislocation, and infection). Multivariable logistic regressions adjusting for age, sex, and Elixhauser comorbidity index were utilized to determine the association between insurance type and surgery rate/complications.RESULTS: We included 245,396 patients for analysis. 14% of Medicaid patients (1,789/12,498) underwent surgery compared to 17% (25,347/149,830) of privately-insured patients and 16% (13,305/83,068) of Medicare patients (pairwise p < 0.001). TTS (Medicaid: 11.7 days, private: 10.6 days (p < 0.001), Medicare: 10.7 days (p = 0.003)) varied by insurance type. Private or Medicare-insured patients were less likely to be readmitted (adjusted odds ratio [OR]: 0.77 [95% confidence interval (CI): 0.63 - 0.93] for private vs Medicaid, and 0.71 [95% CI: 0.59 - 0.88] for Medicare vs Medicaid) and experienced fewer 90-day postoperative complications (adjusted ORs: 0.73 [95% CI: 0.62 - 0.85] for private vs Medicaid, 0.65 [95% CI: 0.55 - 0.77] for Medicare vs Medicaid), such as acute renal failure. TTS was also associated with differing rates of readmissions and complications.CONCLUSION: There are differences in rates of surgery, TTS, and complications after PHFs based on insurance type, representing opportunities for quality-improvement initiatives. Potential methods to address these disparities include implementing standardized PHF protocols and/or reimbursement models and quality metrics that reward equitable treatment. Further research and policy adaptations should be incorporated to decrease barriers patients face and minimize healthcare inequities seen in the treatment of PHFs based on insurance type.

The Price-Quality Mismatch: Are Negotiated Prices for Total Joint Arthroplasty Associated With Hospital Quality in a Large California Health System?
Clinical orthopaedics and related research
2022
Abstract
BACKGROUND: Price variations in healthcare can be caused by quality or factors other than quality such as market share, negotiating power with insurers, or hospital ownership model. Efforts to improve care value (defined as the ratio between health outcomes and price) by making healthcare prices readily accessible to patients are driven by the assumption this can help patients more easily identify high-quality, low-price clinicians and health systems, thus reducing price variations. However, if price variations are driven by factors other than quality, then strategies that involve payments for higher-quality care are unlikely to reduce price variation and improve value. It is unknown whether prices for total joint arthroplasty (TJA) are correlated with the quality of care or whether factors other than quality are responsible for price variation.QUESTIONS/PURPOSES: (1) How do prices insurers negotiate for TJA paid to a single, large health system vary across payer types? (2) Are the mean prices insurers negotiate for TJA associated with hospital quality?METHODS: We analyzed publicly available data from 22 hospitals in a single, large regional health system, four of which were excluded owing to incomplete quality information. We chose to use data from this single health system to minimize the confounding effects of between-hospital reputation or branding and geographic differences in the cost of providing care. This health system consists of large and small hospitals serving urban and rural populations, providing care for more than 3 million individuals. For each hospital, negotiated prices for TJA were classified into five payer types: commercial in-network, commercial out-of-network, Medicare Advantage (plans to which private insurers contract to provide Medicare benefits), Medicaid, and discounted cash pay. Traditional Medicare plans were not included because the prices are set statutorily, not negotiated. We obtained hospital quality measures from the Centers for Medicare and Medicaid Services. Centers for Medicare and Medicaid Services quality measures included TJA-specific complication and readmission rates in addition to hospital-wide patient survey star rating (measure of patient care experience) and total performance scores (aggregate measure of clinical outcomes, safety, patient experience, process of care, and efficiency). We evaluated the association between the mean negotiated hospital prices and Centers for Medicare and Medicaid Services quality measures using Pearson correlation coefficients and Spearman rho across all payer types. Statistical significance was defined as p < 0.0025.RESULTS: The mean ± SD overall negotiated price for TJA was USD 54,500 ± 23,200. In the descriptive analysis, the lowest negotiated prices were associated with Medicare Advantage (USD 20,400 ± 1800) and Medicaid (USD 20,300 ± 8600) insurance plans, and the highest prices were associated with out-of-network care covered by commercial insurance plans (USD 78,800 ± 9200). There was no correlation between the mean negotiated price and TJA complication rate (discounted cash price: r = 0.27, p = 0.29; commercial out-of-network: r = 0.28, p = 0.26; commercial in-network: r = -0.07, p = 0.79; Medicare Advantage: r = 0.11, p = 0.65; Medicaid: r = 0.03, p = 0.92), readmission rate (discounted cash price: r = 0.19, p = 0.46; commercial out-of-network: r = 0.24, p = 0.33; commercial in-network: r = -0.13, p = 0.61; Medicare Advantage: r = -0.06, p = 0.81; Medicaid: r = 0.09, p = 0.74), patient survey star rating (discounted cash price: r = -0.55, p = 0.02; commercial out-of-network: r = -0.53, p = 0.02; commercial in-network: r = -0.37, p = 0.13; Medicare Advantage: r = -0.08, p = 0.75; Medicaid: r = -0.02, p = 0.95), or total hospital performance score (discounted cash price: r = -0.35, p = 0.15; commercial out-of-network: r = -0.55, p = 0.02; commercial in-network: r = -0.53, p = 0.02; Medicare Advantage: r = -0.28, p = 0.25; Medicaid: r = 0.11, p = 0.69) for any of the payer types evaluated.CONCLUSION: There is substantial price variation for TJA that is not accounted for by the quality of care, suggesting that a mismatch between price and quality exists. Efforts to improve care value in TJA are needed to directly link prices with the quality of care delivered, such as through matched quality and price reporting mechanisms. Future studies might investigate whether making price and quality data accessible to patients, such as through value dashboards that report easy-to-interpret quality data alongside price information, moves patients toward higher-value care decisions.CLINICAL RELEVANCE: Efforts to better match the quality of care with negotiated prices such as matched quality and price reporting mechanisms, which have been shown to increase the likelihood of choosing higher-value care in TJA, could improve the value of care.

Has the Use of Electrodiagnostic Studies for Carpal Tunnel Syndrome Changed After the 2016 American Academy of Orthopaedic Surgeons Clinical Practice Guideline?
The Journal of hand surgery
2022
Abstract
PURPOSE: A 2016 American Academy of Orthopaedic Surgeons (AAOS) clinical practice guideline (CPG) de-emphasized the need for electrodiagnostic studies (EDS) for carpal tunnel syndrome (CTS). We tested the hypothesis that use of EDS decreased after the AAOS CPG.METHODS: Using a national administrative claims database, we measured the proportion of patients with a diagnosis of CTS who underwent EDS within 1 year after diagnosis between 2011 and 2019. Using an interrupted time series design, we defined 2 time periods (pre-CPG and post-CPG) and compared EDS usage between the periods using segmented regression analysis. We conducted a subgroup analysis of preoperative EDS usage in patients who underwent carpal tunnel release.RESULTS: Of 2,081,829 patients with CTS, 315,449 (15.2%) underwent EDS within 1 year after diagnosis. The segmented regression analysis showed a decrease in the level of EDS usage after publication of the AAOS CPG (-11.50 per 1,000 patients [95% CI, -1.47 to-0.95 per 1,000 patients]); however, the rate of EDS usage increased in the post-CPG period (+1.75 per 1,000 patients per quarter [95% CI, 0.97-2.54 per 1,000 patients per quarter]). Of 473,753 eligible patients who underwent carpal tunnel release, 139,186 (29.4%) underwent EDS within 6 months before surgery. After publication of the AAOS CPG, preoperative EDS usage decreased by-23.57 per 1,000 patients (95% CI,-37.72 to-9.42 per 1,000 patients). However, these decreasing trends in EDS usage predated the 2016 AAOS CPG.CONCLUSIONS: The overall and preoperative EDS usage for CTS has been decreasing since at least 2014, predating the 2016 AAOS CPG, reflecting the rapid implementation of evidence into practice. However, EDS usage has increased in the post-CPG period, and a considerable proportion of patients who underwent carpal tunnel release still received EDS.CLINICAL RELEVANCE: Given its high costs and disputed value, routine EDS usage should be considered for further deimplementation initiatives.

Cost minimization analysis of the treatment of olecranon fracture in elderly patients: a retrospective analysis.
Current orthopaedic practice
2022; 33 (6): 559-564
Abstract
Operative treatment of olecranon fractures in the elderly can lead to greater complications with similar outcomes to nonoperative treatment. The purpose of this study was to analyze cost differences between operative and nonoperative management of isolated closed olecranon fractures in elderly patients.Using a United States Medicare claims database, the authors identified 570 operative and 1,863 nonoperative olecranon fractures between 2005 and 2014. The authors retrospectively determined cost of treatment from the payer perspective for a 1-year period after initial injury, including any surgical procedure, emergency room care, follow-up care, physical therapy, and management of complications.One year after diagnosis, mean costs per patient were higher for operative treatment (United States dollars [US$]10,694 vs US$2,544). 31.05% of operative cases were associated with a significant complication compared with 4.35% of nonoperative cases. When excluding complications, mean costs per patient were still higher for operative treatment ($7,068 vs $2,320).These findings show that nonoperative management for olecranon fractures in the elderly population leads to fewer complications and is less costly. Nonoperative management may be a higher-value management option for this patient population. These results will help inform management of olecranon fractures as payers shift toward value-based reimbursement models in which quality of care and cost influence surgical decision making.Level IV.

Out-of-Pocket and Total Costs for Common Hand Procedures From 2008 to 2016: A Nationwide Claims Database Analysis.
The Journal of hand surgery
2022
Abstract
PURPOSE: Rising patient out-of-pocket (OOP) costs and financial distress have been associated with reduced access to and delays in care. We evaluated whether OOP and total costs for common hand procedures have increased from 2008 to 2016 and identified key drivers of these costs.METHODS: Using the IBM MarketScan Research Databases, we identified patients who underwent trigger finger release, open carpal tunnel release, thumb carpometacarpal joint arthroplasty, cubital tunnel release, or open treatment of distal radius fracture in the outpatient setting between 2008 and 2016. Patient OOP costs included copayment, coinsurance, and deductible payments. Costs not directly related to medical care, such as transportation and childcare costs, were not included. The overall cost was defined as the sum of the patient OOP cost and insurer reimbursements. We calculated changes in OOP and total overall costs over the study period. We also performed multivariable linear regressions to evaluate the associations between costs and procedure type, insurance type, region, and site of service.RESULTS: The mean patient OOP cost increased by 55% to 71% and the total overall cost increased by 20% to 45%, depending on the procedure, between 2008 and 2016. Facility overall costs increased by 38%, whereas professional overall costs increased by 9%. Procedures performed in an office-based setting were associated with the lowest patient OOP and total overall costs, whereas high-deductible health plans were associated with the highest OOP costs.CONCLUSIONS: Patient OOP and total overall costs increased for the most common hand procedures between 2008 and 2016, driven by a substantial increase in facility costs. Office-based procedures were associated with the lowest costs.CLINICAL RELEVANCE: To alleviate the rising patient cost burden, hand surgeons could incorporate OOP cost considerations into shared decision-making tools, identify patients who may benefit from financial counseling, and shift procedures to an office-based setting.

Prevalence, Burden, and Sources of Out-of-Network Billing in Elective Hand Surgery: A National Claims Database Analysis.
The Journal of hand surgery
2022
Abstract
PURPOSE: Surprise out-of-network (OON) bills can represent a considerable cost burden on patients. However, OON billing remains underexplored in elective, outpatient surgery procedures, which have greater latitude for patient choice. We aimed to answer the following questions: (1) What is the prevalence and magnitude of OON charges in hand surgery? (2) What are the sources of OON charges? and (3) What factors are associated with OON charges?METHODS: We analyzed patient-level data from the Clinformatics Data Mart database. We identified patients undergoing carpal tunnel release, trigger finger release, wrist ganglion removal, de Quervain release, limited palmar fasciectomy, or thumb carpometacarpal arthroplasty at in-network facilities with an in-network primary surgeon. The primary outcome was the proportion of surgical episodes with at least 1 OON charge. Secondary outcomes included the magnitude of potential balance bills (portion of OON bill exclusive of the standardized payment and expected patient cost-sharing), sources of OON charges, and factors associated with OON charges.RESULTS: Of 112,211 elective hand surgery episodes, 8% (9,158) had at least 1 OON charge. OON charges ranged from $1,154 (95% confidence interval, $1,018-$1,289) for wrist ganglion removal to $3,162 (95% confidence interval, $2,902-$3,423) for thumb carpometacarpal arthroplasty. In episodes with OON charges, the major sources of OON charges were anesthesiologists (75% of episodes), durable medical equipment (10% of episodes), and pathologists (9% of episodes). Site of service, geographic region, and health exchange-purchased plans were highly associated with OON charges.CONCLUSIONS: Out-of-network billing can represent a substantial cost burden to patients and should be considered in perioperative decision-making in elective hand surgery.CLINICAL RELEVANCE: Understanding the potential costs related to OON services during a surgical episode, and its drivers, allows surgeons to consider detailed cost discussions during perioperative decision making.

Costs and benefits of routine hemoglobin A1c screening prior to total joint arthroplasty: a cost-benefit analysis.
Current orthopaedic practice
2022; 33 (4): 338-346
Abstract
Poorly controlled diabetes mellitus (DM) increases the risk for periprosthetic joint infection (PJI) after total joint arthroplasty (TJA). While institutional protocols include hemoglobin A1c (HbA1c) screening in TJA patients, the costs and benefits of routine preoperative screening have not been described.The authors created a decision tree model to evaluate short-term costs and risk reduction for PJIs with routine screening of primary total hip arthroplasty (THA) and total knee arthroplasty (TKA) patients. Probabilities and costs were obtained from published sources. They calculated net costs and absolute risk reduction in PJI for routine screening versus no screening. The authors also performed sensitivity analyses of model inputs including probabilistic sensitivity analyses (PSAs) consisting of 10,000 Monte Carlo simulations.In patients with DM, routine screening before THA resulted in net cost savings of $81 per patient with 286 patients needing to be screened to prevent 1 PJI, while screening before TKA incurred net additional costs of $25,810 per PJI prevented. Routine screening in patients with DM undergoing THA or TKA was cost-saving across 75.5% or 21.8% of PSA simulations, respectively. In patients with no history of DM, routine screening before THA or TKA incurred net additional costs of $24,583 or $87,873 per PJI prevented, respectively.Routine HbA1c screening in patients with DM prior to THA with referral of patients with elevated HbA1c for glycemic optimization may prevent PJI and reduce healthcare costs. In contrast, routine screening in patients with DM prior to TKA or in patients with no history of DM is not cost-saving.Economic Level IV.

Is Low-value Testing Before Low-risk Hand Surgery Associated With Increased Downstream Healthcare Use and Reimbursements? A National Claims Database Analysis.
Clinical orthopaedics and related research
2022
Abstract
Minor hand procedures can often be completed in the office without any laboratory testing. Preoperative screening tests before minor hand procedures are unnecessary and considered low value because they can lead to preventable invasive confirmatory tests and/or procedures. Prior studies have shown that low-value testing before low-risk hand surgery is still common, yet little is known about their downstream effects and associated costs. Assessing these downstream events can elucidate the consequences of obtaining a low-value test and inform context-specific interventions to reduce their use.(1) Among healthy adults undergoing low-risk hand surgery, are patients who receive a preoperative low-value test more likely to have subsequent diagnostic tests and procedures than those who do not receive a low-value test? (2) What is the increased 90-day reimbursement associated with subsequent diagnostic tests and procedures in patients who received a low-value test compared with those who did not?In this retrospective, comparative study using a large national database, we queried a large health insurance provider's administrative claims data to identify adult patients undergoing low-risk hand surgery (carpal tunnel release, trigger finger release, Dupuytren fasciectomy, de Quervain release, thumb carpometacarpal arthroplasty, wrist ganglion cyst, or mass excision) between 2011 and 2017. This database was selected for its ability to track patient claims longitudinally with direct provision of reimbursement data in a large, geographically diverse patient population. Patients who received at least one preoperative low-value test, including complete blood count, basic metabolic panel, electrocardiogram, chest radiography, pulmonary function test, and urinalysis within the 30-day preoperative period, were matched with propensity scores to those who did not. Among the 73,112 patients who met our inclusion criteria (mean age 57 ± 14 years; 68% [49,847] were women), 27% (19,453) received at least one preoperative low-value test and were propensity score-matched to those who did not. Multivariable regression analyses were performed to assess the frequency and reimbursements of subsequent diagnostic tests and procedures in the 90 days after surgery while controlling for potentially confounding variables such as age, sex, comorbidities, and baseline healthcare use.When controlling for covariates such as age, sex, comorbidities, and baseline healthcare use, patients in the low-value test cohort had an adjusted odds ratio of 1.57 (95% confidence interval [CI] 1.50 to 1.64; p < 0.001) for a postoperative use event (a downstream diagnostic test or procedure) compared with those who did not have a low-value test. The median (IQR) per-patient reimbursements associated with downstream utilization events in patients who received a low-value test was USD 231.97 (64.37 to 1138.84), and those who did not receive a low-value test had a median of USD 191.52 (57.1 to 899.42) (adjusted difference when controlling for covariates: USD 217.27 per patient [95% CI 59.51 to 375.03]; p = 0.007). After adjusting for inflation, total additional reimbursements for patients in the low-value test cohort increased annually.Low-value tests generate downstream tests and procedures that are known to provide minimal benefit to healthy patients and may expose patients to potential harms associated with subsequent, unnecessary invasive tests and procedures in response to false positives. Nevertheless, low-value testing remains common and the rising trend in low-value test-associated spending demonstrates the need for multicomponent interventions that target change at both the payer and health system level. Such interventions should disincentivize the initial low-value test and the cascade that may follow. Future work to identify the barriers and facilitators to reduce low-value testing in hand surgery can inform the development and revision of deimplementation strategies.Level III, therapeutic study.

Site of service of irrigation and debridement of open finger and hand fractures: a retrospective review of trends and outcomes.
Current orthopaedic practice
2022; 33 (4): 358-362
Abstract
Irrigation and debridement (I&D) of open finger and hand fractures can be performed in the emergency department as opposed to the operating room (OR), though reports of postoperative infection rates vary greatly. The authors hypothesized that I&D of open finger and hand fractures in the OR would decrease over time. They also describe rates of postoperative infection, reoperation, readmission, and costs.A large nationwide administrative claims dataset was retrospectively reviewed to identify patients who underwent I&D after open finger and hand fractures from 2007 to 2016. The incidence of I&D procedures performed outside the OR was reported and trends over the study period were assessed.The proportion of open finger and hand fractures that underwent I&D outside the OR did not change significantly over time. Rates of postoperative surgical site infection, readmission, and reoperation were higher in the OR cohort at 90 days after the index stay. The OR cohort had greater total costs and out-of-pocket costs for the index stay. At 90 days, the OR cohort had greater total cost, but out-of-pocket costs were similar.Site of service for treatment of open finger and hand fractures has not significantly changed from 2007 to 2016. Given that total costs are significantly greater among patients undergoing I&D in the OR, prospective trials are needed to assess the safety of treating open finger and hand fractures outside of the OR to optimize management of these injuries.III.

How do orthopaedic surgery residency program websites feature diversity? An analysis of 187 orthopaedic surgery programs in the United States.
Current orthopaedic practice
2022; 33 (3): 258-263
Abstract
Background: The orthopaedic surgery residency program website represents a recruitment tool that can be used to demonstrate a program's commitment to diversity and inclusion to prospective applicants. The authors assessed how orthopaedic surgery residency programs demonstrated diversity and inclusion on their program websites and whether this varied based on National Institutes of Health (NIH) funding, top-40 medical school affiliation, university affiliation, program size, or geographic region.Methods: The authors evaluated 187 orthopaedic surgery residency program websites for the presence of 12 elements that represented program commitment to diversity and inclusion values, based on prior work and ACGME recommendations. Mann-Whitney U and Kruskal-Wallis tests were used to assess whether NIH funding and other program characteristics were associated with commitment to diversity and inclusion on affiliated residency websites.Results: Orthopaedic surgery residency websites included a mean of 4.9 ± 2.1 diversity and inclusion elements, with 21% (40/187) featuring a majority (7+) of elements. Top 40 NIH funded programs (5.4 ± 2.0) did not have significantly higher website diversity scores when compared with nontop-40 programs (4.8 ± 2.1) (P = 0.250). University-based or affiliated programs (5.2 ± 2.0) had higher diversity scores when compared with community-based programs (3.6 ± 2.2) (P = 0.003).Conclusions: Most orthopaedic surgery residency websites contained fewer than half of the diversity and inclusion elements studied, suggesting opportunities for further commitment to diversity and inclusion. Inclusion of diversity initiatives on program websites may attract more diverse applicants and help address gender and racial or ethnic disparities in orthopaedic surgery.Level of Evidence: Level V.

Google Trends Analysis Shows Increasing Public Interest in Platelet-Rich Plasma Injections for Hip and Knee Osteoarthritis.
The Journal of arthroplasty
2021
Abstract
BACKGROUND: Osteoarthritis is a chronic musculoskeletal condition that frequently affects the hip and knee joints. Given the burden associated with surgical intervention for hip and knee osteoarthritis, patients continue to search for potential nonoperative treatments. One biologic therapy with mixed clinical and basic science evidence for treating osteoarthritis is platelet-rich plasma injections into the affected joint. We used the Google Trends tool to provide a quantitative analysis of national interest in platelet-rich plasma injections for hip and knee osteoarthritis.METHODS: Google Trends parameters were selected to obtain search data from January 2009 to December 2019. Various combinations of "arthritis," "osteoarthritis," "PRP," "platelet-rich plasma," "knee," and "hip" were entered into the Google Trends tool and trend analyses were performed.RESULTS: Three linear models were generated to display search volume trends in the United States for platelet-rich plasma and osteoarthritis, hip osteoarthritis, and knee osteoarthritis, respectively. All models showed increased Google queries as time progressed (P < .001), with R2 ranging from 0.837 to 0.940. Seasonal, income-related, and geographic variations in public interest in platelet-rich plasma for osteoarthritis were noted.CONCLUSION: Our results demonstrate a significant rise in Google queries related to platelet-rich plasma injections for osteoarthritis of the hip and knee since 2009. Surgeons treating hip and knee osteoarthritis patients can expect continued interest in platelet-rich plasma, despite inconclusive clinical and basic science data. Trends in public interest may inform patient counseling, shared decision-making, and directions for future clinical research.

Perioperative Laboratory Markers as Risk Factors for Surgical Site Infection After Elective Hand Surgery.
The Journal of hand surgery
2021
Abstract
PURPOSE: The purpose of this study was to test the null hypothesis that there is no association between perioperative laboratory markers (serum albumin and hemoglobin A1c [HbA1c]) and incidence of surgical site infection (SSI) after soft tissue upper extremity surgery.METHODS: We analyzed patient-level data from a large, insurance-based database containing supplemental laboratory results. We identified patients undergoing soft tissue upper extremity surgery (defined as carpal tunnel release, trigger finger release, wrist ganglion excision, cubital tunnel release, Dupuytren partial fasciectomy, or first dorsal compartment release) with serum albumin or HbA1c measurements within 90 days of surgery. We stratified patients into cohorts based on serum albumin concentration (<3.5 g/dL) and HbA1c (≥7%) thresholds. The primary outcome was incidence of SSI within 30 days following surgery. We constructed multivariable logistic regression models to adjust for patient demographics and baseline comorbidities using the Elixhauser comorbidity index.RESULTS: Patients with hypoalbuminemia experienced an SSI incidence of 3.5% compared to 0.9% in patients with normal serum albumin. In multivariable analysis, the odds ratio of SSI with hypoalbuminemia was 3.32 (95% CI, 2.32-4.65). Patients with HbA1c ≥ 7% experienced an SSI incidence of 1.1% compared to 0.7% in patients with HbA1c < 7%. Multivariable analysis revealed odds ratios for SSI of 1.47 (95% CI, 1.02-2.11) in patients with HbA1c ≥ 7% compared to those with HbA1c < 7%.CONCLUSIONS: Hypoalbuminemia and elevated HbA1c (in patients with diabetes) are risk factors for SSI within 30 days following soft tissue upper extremity surgery. Preoperative measurement of these laboratory markers may be a useful tool for risk stratification and identification of high-risk patients for nutritional or glycemic optimization.TYPE OF STUDY/LEVEL OF EVIDENCE: Prognostic II.

Using Google Trends Data to Track Healthcare Use for Hand Osteoarthritis.
Cureus
2021; 13 (3): e13786
Abstract
Background Google Trends (GT) is a free tool that provides analysis of search traffic for specified terms entered into the Google search engine. In this study, we evaluate the association between public interest in hand osteoarthritis (OA) as determined by GT search volumes and healthcare usage related to hand OA. Methodology We compiled GT data from 2010 to 2017 for the following group of hand OA-related search terms: "hand osteoarthritis," "hand arthritis," "hand swelling," "hand stiffness," and "chronic hand pain." Claims associated with hand OA codes were obtained from an administrative database (14.8 million patients) using International Classification of Diseases codes from 2010 to 2017. We performed trend analysis using univariate linear regression of GT data and hand OA claims. A month-by-month analysis of variation from yearly GT means was conducted for hand OA-related search terms. Results There was increased public interest in hand OA-related search terms from January 2010 to December 2017. Univariate linear regression of GT data for hand OA-related search terms compared with hand OA claims demonstrated a significant positive correlation (p < 0.001, r = 0.707). Peak public interest in hand OA-related search terms was observed in July, May, and June. Conclusions This study demonstrates the ability of GT to track healthcare use related to hand OA. Our data also add to the evidence for monthly variations in public interest related to hand OA. Clinics and surgery centers can employ GT data to anticipate resource utilization by hand OA patients.

Cost-Effectiveness of Open Versus Endoscopic Carpal Tunnel Release.
The Journal of bone and joint surgery. American volume
2021; 103 (4): 343–55
Abstract
Carpal tunnel syndrome is the most common upper-extremity nerve compression syndrome. Over 500,000 carpal tunnel release (CTR) procedures are performed in the U.S. yearly. We estimated the cost-effectiveness of endoscopic CTR (ECTR) versus open CTR (OCTR) using data from published meta-analyses comparing outcomes for ECTR and OCTR.We developed a Markov model to examine the cost-effectiveness of OCTR versus ECTR for patients undergoing unilateral CTR in an office setting under local anesthesia and in an operating-room (OR) setting under monitored anesthesia care. The main outcomes were costs, quality-adjusted life-years (QALYs), and incremental cost-effectiveness ratios (ICERs). We modeled societal (modeled with a 50-year-old patient) and Medicare payer (modeled with a 65-year-old patient) perspectives, adopting a lifetime time horizon. We performed deterministic and probabilistic sensitivity analyses (PSAs).ECTR resulted in 0.00141 additional QALY compared with OCTR. From a societal perspective, assuming 8.21 fewer days of work missed after ECTR than after OCTR, ECTR cost less across all procedure settings. The results are sensitive to the number of days of work missed following surgery. From a payer perspective, ECTR in the OR (ECTROR) cost $1,872 more than OCTR in the office (OCTRoffice), for an ICER of approximately $1,332,000/QALY. The ECTROR cost $654 more than the OCTROR, for an ICER of $464,000/QALY. The ECTRoffice cost $107 more than the OCTRoffice, for an ICER of $76,000/QALY. From a payer perspective, for a willingness-to-pay threshold of $100,000/QALY, OCTRoffice was preferred over ECTROR in 77% of the PSA iterations. From a societal perspective, ECTROR was preferred over OCTRoffice in 61% of the PSA iterations.From a societal perspective, ECTR is associated with lower costs as a result of an earlier return to work and leads to higher QALYs. Additional research on return to work is needed to confirm these findings on the basis of contemporary return-to-work practices. From a payer perspective, ECTR is more expensive and is cost-effective only if performed in an office setting under local anesthesia.Economic and Decision Analysis Level I.

Is Uncontrolled Diabetes Mellitus Associated with Incidence of Complications After Posterior Instrumented Lumbar Fusion? A National Claims Database Analysis.
Clinical orthopaedics and related research
2021
Abstract
Previous research has shown that diabetes mellitus (DM) is associated with postoperative complications, including surgical site infections (SSIs). However, evidence for the association between diabetes control and postoperative complications in patients with DM is mixed. Prior studies relied on a single metric for defining uncontrolled DM, which does not account for glycemic variability, and it is unknown whether a more comprehensive assessment of diabetes control is associated with postoperative complications.(1) Is there a difference in the incidence of SSI after lumbar spine fusion in patients with uncontrolled DM, defined with a comprehensive assessment of glycemic control, compared with patients with controlled DM? (2) Is there a difference in the incidence of other select postoperative complications after lumbar spine fusion in patients with uncontrolled DM compared with patients with controlled DM? (3) Is there a difference in total reimbursements between these groups?We used the PearlDiver Patient Records Database, a national administrative claims database that provides access to the full continuum of perioperative care. We included 46,490 patients with DM undergoing posterior lumbar fusion with instrumentation. Patients were required to be continuously enrolled in the database for at least 1 year before and 90 days after the index procedure. Patients were divided into uncontrolled and controlled DM cohorts, as defined by ICD-9 diagnostic codes. These are based on a comprehensive assessment of glycemic control, including consideration of patient self-monitoring of blood glucose levels, hemoglobin A1c, and the presence/severity of diabetes-related comorbidities. The cohorts differed only by age, insurance type, and Elixhauser comorbidity score. The primary outcome was the incidence of SSI, divided into superficial and deep, within 90 days postoperatively. Secondary complications included the incidence of cerebrovascular events, acute kidney injury, pulmonary embolism, pneumonia, urinary tract infection, blood transfusion, and total reimbursements. These are the sum of reimbursements occurring within 90 days of surgery, which capture the total professional and facility cost burden to the health payer (such as the insurer). We constructed multivariable logistic regression models to adjust for the effects of age, insurance type, and comorbidities.After adjusting for potentially confounding variables including age, insurance type, and comorbidities, we found that patients with uncontrolled DM had an odds ratio for deep SSI of 1.52 (95% confidence interval 1.16 to 1.95; p = 0.002). Similarly, patients with uncontrolled DM had adjusted odds ratios of 1.25 (95% CI 1.01 to 1.53; p = 0.03) for cerebrovascular events, 1.36 (95% CI 1.18 to 1.57; p < 0.001) for acute kidney injury, 1.55 (95% CI 1.16 to 2.04; p = 0.002) for pulmonary embolism, 1.30 (95% CI 1.08 to 1.54; p = 0.004) for pneumonia, 1.33 (95% CI 1.19 to 1.49; p < 0.001) for urinary tract infection, and 1.27 (95% CI 1.04 to 1.53; p = 0.02) for perioperative transfusion. Patients with uncontrolled DM had higher median 90-day total reimbursements than patients with controlled DM: USD 27,915 (interquartile range 5472 to 63,400) versus USD 10,263 (IQR 4101 to 49,748; p < 0.001).Our findings encourage surgeons to take a full diabetic history beyond the HbA1c value, including any self-monitoring of glucose measurements, time in acceptable range for continuous glucose monitors, and/or consideration of the presence/severity of diabetes-related complications before lumbar spine fusion, as HbA1c does not fully capture glycemic control or variability. We emphasize that uncontrolled DM is a clinical, rather than laboratory, diagnosis. Comprehensive diabetes histories should be incorporated into existing preoperative diabetes care pathways and elective surgery could be deferred to improve glycemic control. Future development of an index measure incorporating multidimensional measures of diabetes control (such as continuous or self-glucose monitoring, diabetes-related comorbidities) is warranted.Level III, therapeutic study.

A Cost-Effectiveness Analysis of Smoking-Cessation Interventions Prior to Posterolateral Lumbar Fusion.
The Journal of bone and joint surgery. American volume
2020
Abstract
BACKGROUND: Smoking cessation represents an opportunity to reduce both short and long-term effects of smoking on complications after lumbar fusion and smoking-related morbidity and mortality. However, the cost-effectiveness of smoking-cessation interventions prior to lumbar fusion is not fully known.METHODS: We created a decision-analytic Markov model to evaluate the cost-effectiveness of 5 smoking-cessation strategies (behavioral counseling, nicotine replacement therapy [NRT], bupropion or varenicline monotherapy, and a combined intervention) prior to single-level, instrumented lumbar posterolateral fusion (PLF) from the health payer perspective. Probabilities, costs, and utilities were obtained from published sources. We calculated the costs and quality-adjusted life years (QALYs) associated with each strategy over multiple time horizons and accounted for uncertainty with probabilistic sensitivity analyses (PSAs) consisting of 10,000 second-order Monte Carlo simulations.RESULTS: Every smoking-cessation intervention was more effective and less costly than usual care at the lifetime horizon. In the short term, behavioral counseling, NRT, varenicline monotherapy, and the combined intervention were also cost-saving, while bupropion monotherapy was more effective but more costly than usual care. The mean lifetime cost savings for behavioral counseling, NRT, bupropion monotherapy, varenicline monotherapy, and the combined intervention were $3,291 (standard deviation [SD], $868), $2,571 (SD, $479), $2,851 (SD, $830), $6,767 (SD, $1,604), and $34,923 (SD, $4,248), respectively. The minimum efficacy threshold (relative risk for smoking cessation) for lifetime cost savings varied from 1.01 (behavioral counseling) to 1.15 (varenicline monotherapy). A PSA revealed that the combined smoking-cessation intervention was always more effective and less costly than usual care.CONCLUSIONS: Even brief smoking-cessation interventions yield large short-term and long-term cost savings. Smoking-cessation interventions prior to PLF can both reduce costs and improve patient outcomes as health payers/systems shift toward value-based reimbursement (e.g., bundled payments) or population health models.LEVEL OF EVIDENCE: Economic Level II.

The Influence of Cost Information on Treatment Choice: A Mixed-Methods Study.
The Journal of hand surgery
2020
Abstract
PURPOSE: To test the null hypothesis that exposure to societal cost information does not affect choice of treatment for carpal tunnel syndrome (CTS).METHODS: We enrolled 304 participants using the Amazon Mechanical Turk platform to complete a survey in which participants were given the choice between carpal tunnel release (CTR) or a less-expensive option (orthosis wear) in a hypothetical mild CTS scenario. Patients were randomized to receive information about the societal cost of CTR (cost cohort) or no cost information (control). The primary outcome was the probability of choosing CTR measured on a 6-point ordinal scale. We employed qualitative content analysis to evaluate participants' rationale for their choice. We also explored agreement with various attitudes toward health care costs on an ordinal scale.RESULTS: Participants in the cost cohort exhibited a greater probability of choosing surgery than those in the control cohort. The relative risk of choosing surgery after exposure to societal cost information was 1.43 (95% confidence interval, 1.11-1.85). Among participants who had not previously been diagnosed with CTS (n= 232), the relative risk of choosing surgery after exposure to societal cost information was 1.55 (95% confidence interval, 1.17-2.06). Lack of personal monetary responsibility frequently emerged as a theme in those in the cost cohort who chose surgery. The majority (94%) of participants expressed at least some agreement that health care cost is a major problem whereas only 58% indicated that they consider the country's health care costs when making treatment decisions.CONCLUSIONS: Participants who received societal cost information were more likely to choose the more expensive treatment option (CTR) for mild CTS.CLINICAL RELEVANCE: Exposure to societal cost information may influence patient decision making in elective hand surgery. A complete understanding of this influence is required prior to implementing processes toward greater cost transparency for diagnostic/treatment options. Sharing out-of-pocket costs with patients may be a beneficial approach because discussing societal cost information alone will likely not improve value of care.

Quality Measures to Reduce Opioid Use After Common Soft Tissue Hand and Wrist Procedures.
The Journal of hand surgery
2020
Abstract
To develop quality measures that are clinically important, feasible, usable, and scientifically acceptable for reducing opioid use after soft tissue procedures of the hand and wrist, and which can be used to evaluate quality in hand surgery.A consortium of 9 fellowship-trained hand/upper-limb surgeons with expertise in quality measure development used the RAND Corporation/University of California Los Angeles Delphi Appropriateness method to evaluate the validity of 2 quality measures for reducing opioid use, based on 4 quality indicators (clinical importance, feasibility, usability, and scientific acceptability). Panelists rated each measure on a scale of 1 (definitely not important/feasible/usable/supported) to 9 (definitely important/feasible/usable/supported) in 2 voting rounds with an intervening face-to-face discussion. Agreement was assessed using predetermined criteria. A measure was considered a valid quality measure if it received a median score of 7 or higher for all 4 indicators with no more than 2 panelists rating outside the range of 7 to 9.Panelists achieved agreement on the 4 quality indicators for measuring the proportion of patients undergoing carpal tunnel release, trigger finger release, first dorsal compartment release, or ganglion cyst excision who received structured counseling on opioid use. Panelists also achieved agreement on the 4 quality indicators for measuring the proportion of patients without recent opioid use who did not fill an opioid prescription within 30 days after these procedures. Both candidate quality measures were considered valid.Using a validated consensus-building approach, we developed process and outcome quality measures for reducing opioid use after soft tissue hand surgery that were demonstrated to be valid according to 4 quality indicators.In the era of value-based health care, hand surgeons are assuming increasing responsibility in the prevention of excess opioid prescribing. Quality measures for reducing opioid overprescription can help promote the delivery of evidence-based, high-quality care in hand surgery.

Which Decisions For Management of Carpal Tunnel Syndrome and Distal Radius Fractures Should Be Shared?
The Journal of hand surgery
2020
Abstract
To evaluate, from the surgeon's perspective, the importance, feasibility, and appropriateness of sharing decisions during an episode of care of carpal tunnel syndrome (CTS) or distal radius fracture in patients aged greater than 65 years.A consortium of 9 fellowship-trained hand/upper-limb surgeons used the RAND Corporation/University of California Los Angeles Delphi Appropriateness method to evaluate the importance, feasibility, and appropriateness of sharing 27 decisions for CTS and 28 decisions for distal radius fractures in patients aged greater than 65 years. Panelists rated each measure on a scale of 1 (definitely not important/feasible/appropriate) to 9 (definitely important/feasible/appropriate) in 2 voting rounds with an intervening face-to-face discussion. Panelist agreement and disagreement were assessed using predetermined criteria.Panelists achieved agreement on 16 decisions (29%) as important, 43 (78%) as feasible, and 17 (31%) as appropriate for sharing with patients. Twelve decisions met all 3 of these criteria and were therefore considered important, feasible, and appropriate to share with patients. Examples in CTS included decisions to perform extra confirmatory diagnostic testing, to have surgery, and to perform a steroid injection into the carpal tunnel. Examples in distal radius fracture management included the decision to have surgery, type of pain medication prescribed after surgery, and whether to remove the implant. The remaining 43 decisions did not reach consensus on the importance, feasibility, and appropriateness of sharing with patients.Using a validated consensus-building approach, we identified 12 decisions made during an episode of care for CTS or distal radius fracture that were important, feasible, and appropriate to share with patients from the surgeon's perspective. These decisions merit inclusion in shared decision-making models (eg, preoperative patient preference elicitation tools or decision aids) to align patient preferences with care decisions.Understanding which aspects of care are important, feasible, and appropriate to share with patients may improve patient-centered care by aligning patient preferences with care decisions.

A Cost-Effectiveness Analysis of Corticosteroid Injections and Open Surgical Release for Trigger Finger.
The Journal of hand surgery
2020
Abstract
To evaluate the cost-effectiveness of corticosteroid injection(s) versus open surgical release for the treatment of trigger finger.Using a US health care payer perspective, we created a decision tree model to estimate the costs and outcomes associated with 4 treatment strategies for trigger finger: offering up to 3 steroid injections before to surgery or immediate open surgical release. Costs were obtained from a large administrative claims database. We calculated expected quality-adjusted life-years for each treatment strategy, which were compared using incremental cost-effectiveness ratios. Separate analyses were performed for commercially insured and Medicare Advantage patients. We performed a probabilistic sensitivity analysis using 10,000 second-order Monte Carlo simulations that simultaneously sampled from the uncertainty distributions of all model inputs.Offering 3 steroid injections before surgery was the optimal strategy for both commercially insured and Medicare Advantage patients. The probabilistic sensitivity analysis showed that this strategy was cost-effective 67% and 59% of the time for commercially insured and Medicare Advantage patients, respectively. Our results were sensitive to the probability of injection site fat necrosis, success rate of steroid injections, time to symptom relief after a steroid injection, and cost of treatment. Immediate surgical release became cost-effective when the cost of surgery was below $902 or $853 for commercially insured and Medicare Advantage patients, respectively.Multiple treatment strategies exist for treating trigger finger, and our cost-effectiveness analysis helps define the relative value of different approaches. From a health care payer perspective, offering 3 steroid injections before surgery is a cost-effective strategy.Economic and Decision Analyses II.

Arthrodesis of the Foot or Ankle in Adult Patients with Congenital Clubfoot.
Cureus
2019; 11 (12): e6505
Abstract
Background Although clubfoot that was corrected in childhood rarely recurs in adulthood, persistent deformities or arthritic pain may require further treatment during adulthood. Little evidence exists on the operative procedures utilized in adult clubfoot patients, who were previously treated for congenital clubfoot in childhood, for residual or recurrent deformity or pain. Objective The objective of this study is to characterize the types and frequencies of procedures utilized in adult clubfoot patients, who were previously treated for congenital clubfoot in childhood. Methods A two-pronged approach was employed to describe the operative procedures used in adult clubfoot patients. First, a literature review of all reported cases of operative treatment in adult clubfoot patients who were previously treated in childhood was performed. Second, an analysis of the operative treatments used in adult patients with a diagnosis of congenital clubfoot was conducted using a large, administrative claims database. Results In the literature review, arthrodesis was the most cited operative treatment and reported in four out of the eight studies included. Osteotomies were also reported in the literature. In the database analysis, 94 hindfoot arthrodesis procedures were identified in 73 patients, out of 1,198 adult patients in the database with a diagnosis of congenital clubfoot. Sixty-two patients out of 1,198 adult clubfoot patients received osteotomies. An insufficient number of total ankle arthroplasties were reported for further analysis. Conclusions Operative treatment in adult clubfoot patients who were treated for congenital clubfoot in childhood includes hindfoot arthrodesis and osteotomy procedures. Total ankle arthroplasty has not been reported in the literature for these patients.

Does Societal Cost Information Affect Patient Decision-Making in Carpal Tunnel Syndrome? A Randomized Controlled Trial.
Hand (New York, N.Y.)
2019: 1558944719873399
Abstract
Background: Despite studies demonstrating the effects of out-of-pocket costs on decision-making, the effect of societal cost information on patient decision-making is unknown. Given the considerable societal impact of cost of care for carpal tunnel syndrome (CTS), providing societal cost data to patients with CTS could affect decision-making and provide a strategy for reducing national health care costs. Therefore, we assessed the following hypotheses: (1) there is no difference in treatment choice (surgery vs no surgery) in a hypothetical case of mild CTS between patients randomized to receive societal cost information compared with those who did not receive this information; (2) there are no factors (eg, sex, experience with a previous diagnosis of CTS, or receiving societal cost information) independently associated with the choice for surgery; and (3) there is no difference in attitudes toward health care costs between patients choosing surgery and those who did not. Methods: In this randomized controlled trial using a hypothetical scenario, we prospectively enrolled 184 new and return patients with a nontraumatic upper extremity diagnosis. We recorded patient demographics, treatment choice in the hypothetical case of mild CTS, and their attitudes toward health care costs. Results: Treatment choice was not affected by receiving societal cost information. None of the demographic or illness factors assessed were independently associated with the choice for surgery. Patients declining surgery felt more strongly that doctors should consider their out-of-pocket costs when making recommendations. Conclusions: Providing societal cost information does not seem to affect decision-making and may not reduce the overall health care costs. For patients with CTS, health policy could nudge toward better resource utilization and finding the best care pathways for nonoperative and invasive treatments.

Financial Distress Is Associated With Delay in Seeking Care for Hand Conditions.
Hand (New York, N.Y.)
2019: 1558944719866889
Abstract
Background: As medical costs continue to rise, financial distress due to these costs has led to poorer health outcomes and patient cost-coping behavior. Here, we test the null hypothesis that financial distress is not associated with delay of seeking care for hand conditions. Methods: Eighty-seven new patients presenting to the hand clinic for nontraumatic conditions completed our study. Patients completed validated instruments for measuring financial distress, pain catastrophizing, and pain. Questions regarding delay of care were included. The primary outcome was self-reported delay of the current hand clinic visit. Results: Patients who experience high financial distress differed significantly from those who experience low financial distress with respect to age, race, annual household income, and employment status. Those experiencing high financial distress were more likely to report having delayed their visit to the hand clinic (57% vs 30%), higher pain catastrophizing scores (17.7 vs 7.6), and higher average pain in the preceding week (4.5 vs 2.3). After adjusting for age, sex, and pain, high financial distress (adjusted odds ratio [OR] = 4.90) and pain catastrophizing score (adjusted OR = 0.96) were found to be independent predictors of delay. Financial distress was highly associated with annual household income in a multivariable linear regression model. Conclusions: Patients with nontraumatic hand conditions who experience higher financial distress are more likely to delay their visit to the hand clinic. Within health care systems, identification of patients with high financial distress and targeted interventions (eg, social or financial services) may help prevent unnecessary delays in care.

Variations in Utilization of Carpal Tunnel Release Among Medicaid Beneficiaries.
The Journal of hand surgery
2018
Abstract
PURPOSE: To evaluate the null hypothesis that Medicaid patients receive carpal tunnel release (CTR) at the same time interval from diagnosis as do patients with Medicare Advantage or private insurance.METHODS: We conducted a retrospective review using a database containing claims records from 2007 to 2016. The cohort consisted of patient records with a diagnosis code of carpal tunnel syndrome (CTS) and a procedural code for CTR within 3 years of diagnosis. We stratified patients into 3 groups by insurance type (Medicaid managed care, Medicare Advantage, and private) for an analysis of the time from diagnosis until surgery and use of preoperative electrodiagnostic testing.RESULTS: Of all patients who received CTR within 3 years of diagnosis, Medicaid patients experienced longer intervals from CTS diagnosis to CTR compared with Medicare Advantage and privately insured patients (median, 99 days vs 65 and 62 days, respectively). The Medicaid cohort was significantly less likely to receive CTR within 1 year of diagnosis compared with the Medicare Advantage cohort (adjusted odds ratio [OR]= 0.54) or within 6 months of diagnosis compared with the privately insured cohort (adjusted OR= 0.61). Those in the Medicaid cohort were less likely to receive electromyography and nerve conduction studies within 9 months before surgery compared with their Medicare Advantage (adjusted OR= 0.43) and privately insured (adjusted OR= 0.41) counterparts. These effects were statistically significant after accounting for age, sex, region, and Charlson comorbidity index.CONCLUSIONS: Medicaid managed care patients experience longer times from diagnosis to surgery compared with Medicare Advantage or privately insured patients in this large administrative claims database. Similar variation exists in the use of electrodiagnostic testing based on insurance type.CLINICAL RELEVANCE: Medicaid patients may experience barriers to CTS care, such as delays from diagnosis to surgery and reduced use of electrodiagnostic testing.

Alkyl Isocyanates via Manganese-Catalyzed C-H Activation for the Preparation of Substituted Ureas
JOURNAL OF THE AMERICAN CHEMICAL SOCIETY
2017; 139 (43): 15407–13
Abstract
Organic isocyanates are versatile intermediates that provide access to a wide range of functionalities. In this work, we have developed the first synthetic method for preparing aliphatic isocyanates via direct C-H activation. This method proceeds efficiently at room temperature and can be applied to functionalize secondary, tertiary, and benzylic C-H bonds with good yields and functional group compatibility. Moreover, the isocyanate products can be readily converted to substituted ureas without isolation, demonstrating the synthetic potential of the method. To study the reaction mechanism, we have synthesized and characterized a rare MnIV-NCO intermediate and demonstrated its ability to transfer the isocyanate moiety to alkyl radicals. Using EPR spectroscopy, we have directly observed a MnIV intermediate under catalytic conditions. Isocyanation of celestolide with a chiral manganese salen catalyst followed by trapping with aniline afforded the urea product in 51% enantiomeric excess. This represents the only example of an asymmetric synthesis of an organic urea via C-H activation. When combined with our DFT calculations, these results clearly demonstrate that the C-NCO bond was formed through capture of a substrate radical by a MnIV-NCO intermediate.

Involvement of nitric oxide synthase in matrix metalloproteinase-9-and/or urokinase plasminogen activator receptor-mediated glioma cell migration
BMC CANCER
2013; 13: 590
Abstract
Src tyrosine kinase activates inducible nitric oxide synthase (iNOS) and, in turn, nitric oxide production as a means to transduce cell migration. Src tyrosine kinase plays a key proximal role to control α9β1 signaling. Our recent studies have clearly demonstrated the role of α9β1 integrin in matrix metalloproteinase-9 (MMP-9) and/or urokinase plasminogen activator receptor (uPAR)-mediated glioma cell migration. In the present study, we evaluated the involvement of α9β1 integrin-iNOS pathway in MMP-9- and/or uPAR-mediated glioma cell migration.MMP-9 and uPAR shRNAs and overexpressing plasmids were used to downregulate and upregulate these molecules, respectively in U251 glioma cells and 5310 glioma xenograft cells. The effect of treatments on migration and invasion potential of these glioma cells were assessed by spheroid migration, wound healing, and Matrigel invasion assays. In order to attain the other objectives we also performed immunocytochemical, immunohistochemical, RT-PCR, Western blot and fluorescence-activated cell sorting (FACS) analysis.Immunohistochemical analysis revealed the prominent association of iNOS with glioblastoma multiforme (GBM). Immunofluorescence analysis showed prominent expression of iNOS in glioma cells. MMP-9 and/or uPAR knockdown by respective shRNAs reduced iNOS expression in these glioma cells. RT-PCR analysis revealed elevated iNOS mRNA expression in either MMP-9 or uPAR overexpressed glioma cells. The migration potential of MMP-9- and/or uPAR-overexpressed U251 glioma cells was significantly inhibited after treatment with L-NAME, an inhibitor of iNOS. Similarly, a significant inhibition of the invasion potential of the control or MMP-9/uPAR-overexpressed glioma cells was noticed after L-NAME treatment. A prominent reduction of iNOS expression was observed in the tumor regions of nude mice brains, which were injected with 5310 glioma cells, after MMP-9 and/or uPAR knockdown. Protein expressions of cSrc, phosphoSrc and p130Cas were reduced with simultaneous knockdown of both MMP-9 and uPAR.Taken together, our results from the present and earlier studies clearly demonstrate that α9β1 integrin-mediated cell migration utilizes the iNOS pathway, and inhibition of the migratory potential of glioma cells by simultaneous knockdown of MMP-9 and uPAR could be attributed to the reduced α9β1 integrin and iNOS levels.
