Assessment of Implicit Gender Bias During Evaluation of Procedural Competency Among Emergency Medicine Residents.

Importance: Gender disparities exist throughout medicine. Recent studies have highlighted an attainment gap between male and female residents in performance evaluations on Accreditation Council for Graduate Medical Education (ACGME) milestones. Because of difficulties in blinding evaluators to gender, it remains unclear whether these observed disparities are because of implicit bias or other causes. Objective: To estimate the magnitude of implicit gender bias in assessments of procedural competency in emergency medicine residents and whether the gender of the evaluator is associated with identified implicit gender bias. Design, Setting, and Participants: A cross-sectional study was performed from 2018 to 2020 in which emergency medicine residency faculty assessed procedural competency by evaluating videos of residents performing 3 procedures in a simulated environment. They were blinded to the intent of the study. Proceduralists were filmed performing each procedure from 2 different viewpoints simultaneously by 2 different cameras. One was a gender-blinded (ie, hands-only) view, and the other a wide-angled gender-evident (ie, whole-body) view. The faculty evaluators viewed videos in a random order and assessed procedural competency on a global rating scale with extensive validity evidence for the evaluation of video-recorded procedural performance. Main Outcomes and Measures: The primary outcome was to determine if there was a difference in the evaluation of procedural competency based on gender. The secondary outcome was to determine if there was a difference in the evaluations based on the gender of the evaluator. Results: Fifty-one faculty evaluators enrolled from 19 states, with 22 male participants (43.1%), 29 female participants (56.9%), and a mean (SD) age of 37 (6.4) years. Each evaluator assessed all 60 procedures: 30 gender-blinded (hands-only view) videos and 30 identical gender-evident (wide angle) videos. There were no statistically significant differences in the study evaluators' scores of the proceduralists based on their gender, and the gender of the evaluator was not associated with the difference in mean scores. Conclusions and Relevance: In this study, we did not identify a difference in the evaluation of procedural competency based upon the gender of the resident proceduralist or the gender of the faculty evaluator.

A Meta-analysis of Long-term Mortality and Associated Risk Factors following Lower Extremity Amputation.

BACKGROUND: A majority of patients undergoing lower limb amputations have diabetes or peripheral artery disease. Despite improvements in care, there remains a substantial perioperative mortality associated with these procedures. Less well-defined is the mortality risk to these patients going forward, once outside the perioperative period. The aim of this systematic review is to summarize and pool the available data to determine the long-term mortality associated with amputation in the diabetic and peripheral vascular patient, as well as to define specific factors associated with increased mortality risk. METHODS: Four databases were searched from January 2005 through July 2015 using the Medical Subject Headings terms "amputation," "lower extremity," and "mortality." Inclusion criteria were observational and cohort studies where ≥50% of amputations were attributable to diabetic or vascular etiologies. Final article inclusion was approved by reviewer consensus. Bias was assessed with the Joanna Briggs Institute Critical Appraisal Tool for cohort studies. RESULTS: Of the 365 unique records screened, 43 abstracts and 21 full articles were reviewed and 16 studies ultimately included. The overall mortality rate was 47.9%, 61.3%, 70.6%, and 62.2% at 1-, 2-, 3- and 5-year follow-up, respectively. In addition to diabetes and peripheral vascular disease, comorbid factors associated with at least a 2-fold increased mortality were coronary artery disease, cerebrovascular disease, renal dysfunction, American Society of Anesthesiologists class ≥4, dementia, and nonambulatory status. Surgical factors, including higher amputation level and need for staged surgery with up-front guillotine amputation, were also correlated with increased mortality. CONCLUSIONS: The overall mortality rate after primary lower limb amputation in the diabetic and peripheral vascular population is substantial, and should not be underestimated when making decisions regarding limb salvage. Similar to patients undergoing revascularization, comorbid conditions associated with higher mortality should be optimized before surgery whenever possible.
