Effect of resident and assessor gender on entrustment-based observational assessment in an internal medicine residency program

Background: Implicit gender bias leads to differences in assessment. Studies examining gender differences in resident milestone assessment data demonstrate variable results. The purpose of this study was to determine if observational entrustment scores differ by resident and assessor gender in a program of assessment based on discrete, observable skills. Methods: We analyzed overall entrustment scores and entrustment scores by Accreditation Council for Graduate Medical Education (ACGME) core competency for 238 residents (49% female) from 396 assessors (38% female) in one internal medicine residency program from July 2012 to June 2019. We conducted analyses at 1-12 months, 1-36 months, 1-6 months, 7-12 months, and 31-36 months. We used linear mixed-effect models to assess the role of resident and assessor gender, with resident-specific and assessor-specific random effect to account for repeated measures. Results: Statistically significant interactions existed between resident and assessor gender for overall entrustment at 1-12 months (p < 0.001), 1-36 months (p< 0.001), 1-6 months (p<0.001), 7-12 months (p=0.04), and 31-36 months (p<0.001). However, group differences were not statistically significant. In several instances an interaction was significant between resident and assessor gender by ACGME core competency, but there were no statistically significant group differences for all competencies at any time point. When applicable, subsequent analysis of main effect of resident or assessor gender independently of one another revealed no statistically significant differences. Conclusions: No significant differences in entrustment scores were found based on resident or assessor gender in our large, robust entrustment-based program of assessment. Determining the reasons for our findings may help identify ways to mitigate gender bias in assessment.

The Influence of Applicant and Reviewer Gender on Resident Selection for Internal Medicine

Background: While gender bias in medicine, including physician training, has been well described, less is known about gender bias in the selection process for post graduate residency training programs. This analysis reviews the potential role of gender on resident selection for an internal medicine residency program. Methods: File review and interview overall and component scores were analyzed based on the gender of the applicant. File review scores were further analyzed based on the reviewer’s gender. Results: Women applicants scored higher than men applicants on their file review. There were no differences in any one component score except for leadership in art. Women file reviewers scored applicants higher than men file reviewers, but there was no difference between gender scores. There was no difference in overall or component interview scores between men or women applicants. Scoring did not impact the expected rank performance of applicants based on gender at any stage of the selection process. Conclusions: While higher scores were observed in women applicants upon their file review, and women reviewers provided higher file review scores, this did not appear to impact the expected number of women and men applicants at each stage of the applicant process. This suggests a potential lack of gender bias at these stages of applicant selection.
