The influence of resident and faculty gender on assessments in anesthesia competency-based medical education

PURPOSE: Competency-based medical education (CBME) relies on frequent workplace-based assessments of trainees, providing opportunities for conscious and implicit biases to reflect in these assessments. We aimed to examine the influence of resident and faculty gender on performance ratings of residents within a CBME system. METHODS: This retrospective cohort study took place from August 2017 to January 2021 using resident assessment data from two workplace-based assessments: the Anesthesia Clinical Encounter Assessment (ACEA) and Entrustable Professional Activities (EPAs). Self-reported gender data were also extracted. The primary outcome—gender-based differences in entrustment ratings of residents on the ACEA and EPAs—was evaluated using mixed-effects logistic regression, with differences reported through odds ratios and confidence intervals (α = 0.01). Gender-based differences in the receipt of free-text comments on the ACEA and EPAs were also explored. RESULTS: In total, 14,376 ACEA and 4,467 EPA assessments were analyzed. There were no significant differences in entrustment ratings on either assessment tool between men and women residents. Regardless of whether assessments were completed by men or women faculty, entrustment rates between men and women residents were not significantly different for any postgraduate year level. Additionally, men and women residents received strengths-related and actions-related comments on both assessments at comparable frequencies, irrespective of faculty gender. CONCLUSION: We found no gender-based differences in entrustment ratings for both the ACEA and EPAs, which suggests an absence of resident gender bias within this CBME system. Given considerable heterogeneity in rater leniency, future work would be strengthened by using rater leniency-adjusted scores rather than raw scores.
