Race, Postoperative Complications, and Death in Apparently Healthy Children

Abstract

BACKGROUND: That African American (AA) patients have poorer surgical outcomes compared with their white peers is established. The prevailing presumption is that these disparities operate within the context of a higher preoperative comorbidity burden among AA patients. Whether these racial differences in outcomes exist among apparently healthy children (traditionally expected to have low risk of postsurgical complications) has not been previously investigated. METHODS: We performed a retrospective study by analyzing the National Surgical Quality Improvement Program–Pediatric database from 2012 through 2017 and identifying children who underwent inpatient operations and were assigned American Society of Anesthesiologists physical status 1 or 2. We used univariable and risk-adjusted logistic regression to estimate the odds ratios and their 95% confidence intervals (CIs) of postsurgical outcomes comparing AA to white children. RESULTS: Among 172 549 apparently healthy children, the incidence of 30-day mortality, postoperative complications, and serious adverse events were 0.02%, 13.9%, and 5.7%, respectively. Compared with their white peers, AA children had 3.43 times the odds of dying within 30 days after surgery (odds ratio: 3.43; 95% CI: 1.73–6.79). Compared with being white, AA had 18% relative greater odds of developing postoperative complications (odds ratio: 1.18; 95% CI: 1.13–1.23) and 7% relative higher odds of developing serious adverse events (odds ratio: 1.07; 95% CI: 1.01–1.14). CONCLUSIONS: Even among apparently healthy children, being AA is strongly associated with a higher risk of postoperative complications and mortality. Mechanisms underlying the established racial differences in postoperative outcomes may not be fully explained by the racial variation in preoperative comorbidity.
