To compare 30-day complication rates after prolapse repair and sling procedures across racial/ethnic groups, and evaluate trends over time.

We identified female patients in a national outcomes-based database who underwent prolapse repair and/or sling procedures between January 1, 2010 and December 31, 2018, stratified by race and ethnicity, and compared 30-day postoperative complication rates. Multivariable logistic regression adjusted for confounders. Trends in complication rates over time were evaluated using a test for trend (p-trend).

We identified 70,540 prolapse repairs and 23,968 sling procedures. Following prolapse repairs, Black women had the highest complication rates (11%, vs 8% for Hispanic and 9% for both White and Other race/ethnicity women, P <0.01). Following sling procedures, there were few differences in complication rates between groups. After adjustments, Black women still experienced higher odds of any complication (aOR 1.15, 95% CI 1.03-1.29), particularly a vascular complication (venous thromboembolism or transfusion) (aOR 2.50, 95% CI 2.05-3.04) following prolapse repair procedures. Hispanic women had higher odds of vascular complications after prolapse repair (aOR 1.47, 95% CI 1.23-1.76) and slings (aOR 2.40, 95% CI 1.53-3.76). Trends from 2010-2018 showed a decrease in vascular complication rates among non-Black women after prolapse repairs, but rates among Black women did not decrease.

Black women have higher odds of experiencing postoperative complications after prolapse repair procedures, particularly vascular complications. Vascular complication rates after prolapse repair decreased over time for all racial/ethnic groups except Black women. Hispanic women have higher odds of vascular complications after prolapse repair and slings than other racial/ethnic groups.
