Trends in surgical approach to hysterectomy and perioperative outcomes in Michigan hospitals from 2010 through 2020.

The objective of this study was to determine the trends in surgical approach to hysterectomy over the last decade and compare perioperative outcomes and complications. This retrospective cohort study used clinical registry data from the Michigan Hospitals that participated in Michigan Surgical Quality Collaborative (MSQC) from January 1st, 2010 through December 30th, 2020. A multigroup time series analysis was performed to determine how surgical approach to hysterectomy [open/TAH, laparoscopic (TLH/LAVH), and robotic-assisted (RA)] has changed over the last decade. Abnormal uterine bleeding, uterine fibroids, chronic pelvic pain, pelvic organ prolapse, endometriosis, pelvic mass, and endometrial cancer were the most common indications for hysterectomy. The open approach to hysterectomy declined from 32.6 to 16.9%, a 1.9-fold decrease, with an average decline of 1.6% per year (95% CI - 2.3 to - 0.9%). Laparoscopic-assisted hysterectomies decreased from 27.2 to 23.8%, a 1.5-fold decrease, with an average decrease of 0.1% per year (95% CI - 0.7 to 0.6%). Finally, the robotic-assisted approach increased from 38.3 to 49.3%, a 1.25-fold increase, with an average of 1.1% per year (95% CI 0.5 to 1.7%). For malignant cases, open procedures decreased from 71.4 to 26.6%, a 2.7-fold decrease, while RA-hysterectomy increased from 19.0 to 58.7%, a 3.1-fold increase. After controlling for the confounding variables age, race, and gynecologic malignancy, RA hysterectomy was found to have the lowest rate of complications when compared to the vaginal, laparoscopic and open approaches. Finally, after controlling for uterine weight, black patients were twice as likely to undergo an open hysterectomy compared to white patients.
