Gender and Racial/Ethnic Disparities in Operative Volumes of Graduating General Surgery Residents

Abstract

Introduction: Gender disparities in resident operative experience have been described; however, their etiology is poorly understood, and racial/ethnic disparities have not been explored. This study investigated the relationship between gender, race/ethnicity, and surgery resident case volumes.

Materials and methods: A retrospective analysis of graduating general surgery resident case logs (2010-2020) at an academic medical center was performed. Self-reported gender and race/ethnicity data were collected from program records. Residents were categorized as underrepresented in medicine (URM) (Black, Hispanic, Native American) or non-URM (White, Asian). Associations between gender and URM status and major, chief, and teaching assistant (TA) mean case volumes were analyzed using t-tests.

Results: The cohort included 80 residents: 39 female (48.8%) and 17 URM (21.3%). Compared to male residents, female residents performed fewer TA cases (33 versus 47, P < 0.001). Compared to non-URM residents, URM residents graduated with fewer major (948 versus 1043, P = 0.008) and TA cases (32 versus 42, P = 0.038). Male URM residents performed fewer TA cases than male non-URM residents (32 versus 50, P = 0.031). Subanalysis stratified by graduation year demonstrated that from 2010 to 2015, female residents performed fewer chief (218 versus 248, P = 0.039) and TA cases (29 versus 50, P = 0.001) than male residents. However, from 2016 to 2020, when gender parity was achieved, no significant associations were observed between gender and case volumes.

Conclusions: Female and URM residents perform fewer TA and major cases than male non-URM residents, which may contribute to reduced operative autonomy, confidence, and entrustment. Prioritizing gender and URM parity may help decrease case volume gaps among underrepresented residents.
