Racial Bias on the Emergency Medicine Standardized Letter of Evaluation

Abstract

ABSTRACT Background Studies on components of residency applications have shown evidence of racial bias. The Standardized Letter of Evaluation (SLOE) is an assessment measure for emergency medicine (EM) residency applications and, as more specialties opt to use SLOEs in place of narrative letters of recommendation, understanding bias on standardized assessments is essential. Objective To determine whether there is a difference in rankings on the EM SLOE between underrepresented in medicine (UIM) and non-UIM applicants, White and non-White applicants, and to examine whether differences persist after controlling for other characteristics. Methods The sample was drawn from medical students who applied to EM residency at the study institution in 2019. We compared rankings between UIM and non-UIM students and between students of each individual race/ethnicity and White students, after controlling for United States Medical Licensing Examination Step scores, Alpha Omega Alpha status, type of school (US MD, US DO, internation medical graduate), Medical Student Performance Evaluation class percentile, affiliated program vs visiting clerkship SLOE, gender and the interaction of race/ethnicity and gender, and adjusted for students submitting multiple SLOEs, using ordinal regression. Results There were 1555 applicants to the study institution in 2019; 1418 (91.2%) had a SLOE and self-identified race/ethnicity. After controlling for applicant characteristics, non-UIM students were significantly more likely to be ranked higher than UIM students on “Rank Against Peers,” (OR 1.46, 95% CI 1.03-2.07) and Grade (OR 1.46, 95% CI 1.05-2.04). Conclusions Analysis of EM SLOEs submitted to our institution demonstrates racial bias on this standardized assessment tool, which persists after controlling for other performance predictors.
