Is there a gender bias in milestones evaluations in general surgery residency training?

Studies of gender disparity in surgical training have yielded conflicting results. We hypothesize that there is no influence of gender on resident self-evaluation Milestone (SEM) scores and those assigned by the Clinical Competency Committee (CCC). 42 residents (25 male & 17 female) and faculty completed 300 Accreditation Council for Graduate Medical Education (ACGME) Milestone evaluations over a 4-year period. Two-way ANOVA, intraclass correlations coefficients, and general linear mixed models were used for analysis. CCC Milestone scores from 150 evaluations, 51 (34%) for female residents and 99 (66%) for male residents, were compared to corresponding SEM scores. There is a high interrater reliability (self vs. CCC). There was a significant increase in scores with advancing PGY levels (p 0.05) was noted. We found no significant differences in Milestones scores between male and female residents as determined by the CCC. Both scores improved significantly as residents progressed in training. •No differences in surgical resident self-assessed Milestones scores and Clinical Competency Committee evaluations when stratified by gender.•Milestone scores increased with experience as expected.•Providing new trainees with early mentoring and coaching is essential
