Impact of Race, Ethnicity, Insurance, and Procedural Timing on Sterilization Method.

Abstract

Objective: This study aims to determine if race, ethnicity, insurance status, or procedural timing is associated with type of sterilization procedure. Methods: A retrospective cohort study was performed. The study population included women who underwent elective sterilization at one institution from January 2010 to December 2020. The medical record was reviewed to obtain age, race, ethnicity, procedure type and timing, and insurance status. Race and ethnicity groups included were Asian, non-Hispanic Black, Hispanic, or non-Hispanic White. Timing was divided into peripartum (at the time of cesarean section or before discharge after vaginal delivery) and interval procedures. Multivariate logistic regression was performed to assess the association of procedure type with race, ethnicity, insurance status, and timing. In addition, a sensitivity analysis was performed for procedures after January 1, 2016, to determine if the associations with the above categories differed. Results: A sample of 2,041 individuals received sterilization procedures, and 1,115 were included in the analysis: 70% (782) of sterilizations were performed during the peripartum period, and 60% (670) of women had public insurance. On multivariate analysis, both non-Hispanic Black (odds ratio [OR] 0.54 95% confidence interval [CI] 0.32-0.89) and Asian (OR 0.23 95% CI 0.06-0.72) individuals were less likely to have salpingectomy (SL) when compared with non-Hispanic White individuals. On sensitivity analysis for procedures after January 1, 2016, non-Hispanic Black (OR 0.31 95% CI 0.17-0.56), Hispanic (OR 0.31 95% CI 0.14-0.66), and Asian (OR 95% CI 0.04-0.54) individuals were less likely to have when compared with non-Hispanic White individuals. Conclusion: Tubal ligation is more frequently performed in our health system, and we identified critical disparities in performance of SL for sterilization.
