The Effect of Implicit Bias on the OB/GYN Residency Application Process.

Abstract

Background Medical students from racially minoritized backgrounds receive negative evaluations more frequently, possibly from implicit bias. Objective To determine if a preference for White applicants over Asian and Black applicants exists among resident and attending reviewers of obstetrics and gynecology (OB/GYN) residency applications. Methods In 2021, we sampled academic OB/GYN physicians from 6 academic institutions to randomly receive questionnaire form A or B, each containing 4 contrived Electronic Residency Application Service profiles stratified by United States Medical Licensing Examination scores; institutions attended; and strength of recommendation letters into top-, mid-, and low-tiers. Form A applicants were White top-tier, White mid-tier without resilience, Asian mid-tier with resilience, and White low-tier. Form B applicants were Black top-tier, Asian mid-tier without resilience, White mid-tier with resilience, and White low-tier applicants. Both questionnaires' profiles were identical except for applicants' names and races. The primary outcome was participants' rankings of applicants from most to least desirable. Baseline characteristics of participants were compared with chi-square tests. Rankings were compared using generalized estimating equations to calculate the odds ratio (significance P<.05). Results One hundred and ninety-one were invited to participate; 109 participants started the questionnaire, and 103 ranked applicants (response rate 54%). Fifty-three participants completed form A, and 56 completed form B. No significant differences were found in participants' demographics. Participants frequently ranked White applicants significantly more highly than Black applicants (-3.3, 95% CI -3.5, -3.1) and Asian applicants (-3.3, 95% CI -3.5, -3.1). Conclusions Despite identical qualifications, a stronger preference for White applicants over Black or Asian applicants was found.
