High-Volume Surgeons and Reducing Racial Disparities in Route of Hysterectomy.

ABSTRACT

STUDY OBJECTIVE: To examine racial disparities in route of hysterectomy and perioperative outcomes before and after expansion of high-volume minimally invasive surgeons (>10 minimally invasive hysterectomies (MIH)/year) DESIGN: Retrospective cohort study SETTING: Multi-center academic teaching institution PATIENTS All patients who underwent a scheduled hysterectomy for benign indications during 2018 (pre-intervention) and 2022 (post-intervention) INTERVENTIONS: Recruitment of Fellowship in Minimally Invasive Gynecologic Surgery (FMIGS)- trained faculty and increased surgical training for academic specialists in obstetrics and gynecology occurred in 2020. MEASUREMENTS AND MAIN RESULTS: Patients in the pre-intervention cohort (n=171) were older (median age 45 years vs. 43 years, p=0.003) while patients in the post-intervention cohort (n=234) had a higher burden of comorbidities (26% ASA class III vs. 19%, p=0.03). Uterine weight was not significantly different between cohorts (p=0.328). Between the pre-intervention and post-intervention cohorts, high-volume minimally invasive surgeons increased from 27% (n=4) to 44% (n=7) of those performing hysterectomies within the division and percentage of hysterectomies performed via minimally invasive route increased (63% vs. 82%, p<0.001). In the pre-intervention cohort, Black patients had a lower percentage of hysterectomies performed via minimally invasive route compared to White patients (Black = 56% MIH vs. White = 76% MIH, p=0.014). In the post-intervention cohort, differences by race were no longer significant (Black = 78% MIH vs. White = 87% MIH, p= 0.127). There was a significant increase (22%) in MIH for Black patients between cohorts (p<0.001). After adjusting for age, BMI, ASA class, prior surgery, and uterine weight, disparities by race were no longer present in the post-intervention cohort. Perioperative outcomes including length of stay (p<0.001), infection rates (p=0.002) and blood loss (p=0.01) improved post-intervention. CONCLUSION: Increasing FMIGs-trained gynecologic surgeons and providing more opportunities in robotic/laparoscopic training for academic specialists may improve access to MIH for Black patients and reduce disparities.
