Impact of Race and Ethnicity on Perioperative Outcomes During Hysterectomy for Endometriosis.

Study Objective: To assess whether complications incurred during hysterectomy for the treatment of endometriosis differ among racial-ethnic groups.

Design: Retrospective cohort study.

Setting: American College of Surgeons National Surgical Quality Improvement Program database from 2014 to 2019. This database is a robust, comprehensive, multi-institutional database with nearly 700 participating hospitals.

Patients: Patients with a diagnosis of endometriosis or with an endometriosis-associated symptom as the primary indication for surgery and surgical intraoperative documentation of endometriosis.

Interventions: Compare perioperative complications based on patient race and ethnicity.

Measurements And Main Results: A total of 5639 patients underwent hysterectomy for endometriosis; of these, 4368 were White patients (77.5%), 528 Black patients (9.4%), 491 Hispanic patients (8.7%), 252 Asian patients (4.5%). There was no association between location of endometriosis and patient race and ethnicity. However, White patients had highest rate, and Asian patients had the lowest rate of laparoscopic hysterectomy, 85.3% vs 69.8%, respectively (p <.01). In addition, there were differences in concomitant procedures performed at time of hysterectomy based on race and ethnicity, with White patients having the highest rates of adnexal/peritoneal surgery at 12.5% (p <.01) compared with patients of the other racial and ethnic groups. Asian patients had the highest rate of ureteral surgery at 6.8% (p <.01) and highest rate of intestinal surgery at 16.3% (p <.01) compared with patients of other racial and ethnic groups. There was no association of rates of concomitant bladder surgery, appendectomy, or rectal surgery with patient race and ethnicity. Black patients had the highest rate of minor complications at 13.5% (p <.01) and the highest rate of major complications at 6.6% (p <.01) compared with patients of other racial and ethnic groups. After multivariable analysis, Black patients still had increased odds of having a major complication compared with patients of other racial and ethnic groups even after controlling for patient characteristics and perioperative factors such as endometriosis lesion location, surgical approach, and concomitant procedures (odds ratio 1.64; 95% confidence interval, 1.10-2.45).

Conclusion: Endometriosis lesion location did not differ with patient race and ethnicity. However, patient race and ethnicity did have an impact on the surgical approach and the concomitant surgical procedures performed at time of hysterectomy. Black patients had the highest odds of major complications.
