Abstract

Abstract : OBJECTIVE: To examine whether there are racial and ethnic differences in postoperative complications after nonobstetric surgery during pregnancy in the United States. METHODS: We conducted a secondary analysis of the prospective ACS NSQIP (American College of Surgeons National Surgical Quality Improvement) program from 2005 to 2012. We assessed pregnant women 18–50 years without prior surgery in the preceding 30 days who underwent a nonobstetric surgery. Race and ethnicity were categorized as non-Hispanic Black, Hispanic, and non-Hispanic White (reference). The primary outcome was a composite of 30-day major postoperative complications inclusive of cardiovascular, pulmonary, and infectious complications, reoperation, unplanned readmission, blood transfusion, and death. We used modified Poisson regression to estimate the relative risk of complications. RESULTS: Among 3, 093 pregnant women, 18% were non-Hispanic Black, 20% Hispanic, and 62% non-Hispanic White. The most common surgeries were appendectomy (36%) and cholecystectomy (19%). Black women (18%) were more likely to be assigned American Society of Anesthesiologists (ASA) physical status class III or higher than their White (12%) or Hispanic (9%) peers. Non-Hispanic Black pregnant women had a higher risk of 30-day major postoperative complications compared with their White peers (9% vs 6%; adjusted relative risk [aRR] 1.41, 95% CI 1.11–1.99). This difference persisted when limiting the analysis to apparently healthy women (ASA class I or II) (7% vs 4%; aRR 1.64, 95% CI 1.08–2.50), those who underwent appendectomy (10% vs 3%; aRR 2.36, 95% CI 1.13–4.96), and when appendectomy and cholecystectomy were performed by laparoscopy (7% vs 3%; aRR 2.62, 95% CI 1.22–5.58). Hispanic pregnant women were not at an increased risk of complications compared with non-Hispanic pregnant White women. CONCLUSIONS: Pregnant non-Hispanic Black women were at higher risk of major postoperative complications after nonobstetric surgery compared with their White counterparts. Abstract : Pregnant non-Hispanic Black women were at higher risk of major postoperative complications after nonobstetric surgery compared with their White counterparts.
