Racial Disparities in Surgery

Abstract

Objective:. To determine if Black race is associated with worse short-term postoperative morbidity and mortality when compared to White race in a contemporary, cross-specialty-matched cohort. Background:. Growing evidence suggests poorer outcomes for Black patients undergoing surgery. Methods:. A retrospective analysis was conducted comprising of all patients undergoing surgery in the National Surgical Quality Improvement Program dataset between 2012 and 2018. One-to-one coarsened exact matching was conducted between Black and White patients. Primary outcome was rate of 30-day morbidity and mortality. Results:. After 1:1 matching, 615,118 patients were identified. Black race was associated with increased rate of all-cause morbidity (odds ratio [OR] = 1.10, 95% confidence interval [CI] 1.08–1.13, P 48 hours (OR = 1.14, 95% CI 1.02–1.29, P < 0.001), progressive renal insufficiency (OR = 1.63, 95% CI 1.43–1.86, P < 0.001), acute renal failure (OR = 1.39, 95% CI 1.16–1.66, P < 0.001), cardiac arrest (OR = 1.47, 95% CI 1.24–1.76 P < 0.001), bleeding requiring transfusion (OR = 1.39, 95% CI 1.34–1.43, P < 0.001), DVT/thrombophlebitis (OR = 1.24, 95% CI 1.14–1.35, P < 0.001), and sepsis/septic shock (OR = 1.09, 95% CI 1.03–1.15, P < 0.001). Black patients were also more likely to have a readmission (OR = 1.12, 95% CI 1.10–1.16, P < 0.001), discharge to a rehabilitation center (OR = 1.73, 95% CI 1.66–1.80, P < 0.001) or facility other than home (OR = 1.20, 95% CI 1.16–1.23, P < 0.001). Conclusion and Relevance:. This contemporary matched analysis demonstrates an association with increased morbidity, mortality, and readmissions for Black patients across surgical procedures and specialties.
