Abstract

Study objectives: The primary objective of this study is to identify patient characteristics associated with postoperative complications or readmissions following hysterectomy for a benign indication.

Design: Retrospective cohort

Setting: The Surgical Gynecology Scorecard Database (SGSD) includes performance measures and patient outcomes for hysterectomies at 7 sites in Ontario, Canada.

The patients: People who underwent a hysterectomy for benign gynecological indication and registered in the SGSD between July 2016 and June 2019 were included in this study.

Measurements: Two outcomes of interest were considered, (1) complications grade II or higher on the Clavien-Dindo grading scale and (2) emergency room visits or hospital readmissions in the 6 weeks after the operation. Logistic models were generated to determine associations between the outcome of interest and potential predictors using a mixed-stage AIC selection algorithm.

Principle results: 2792 patients underwent hysterectomy for a benign indication during the study period with an average age of 52.6±11.7 years and an average BMI of 29.0±6.7 kg/m2. The most common surgical indications were abnormal uterine bleeding (33.3%) and fibroids (33.6%). Previous caesarean section (aOR 1.22; 95% CI 1.04-1.42), ASA class ≥ 3 (2.31; 1.42-3.99), preoperative anemia (1.51; 1 ,12-2.02) and a laparotomy approach (1.73; 1.30-2.29) were associated with an increased risk of complications. Perioperative complications (2.95; 2.12-4.08), preoperative anemia (1.43; 1.03-1.98) and vaginal approach (1.94; 126-2.96) or laparotomy (1.64; 1.10-2.43) were associated with an increased likelihood of emergency department visit or hospital readmission.

Conclusion: This study identified several important risk factors for complications after hysterectomy. The utility of these data is significant in helping to improve counseling for patients undergoing hysterectomy and potentially optimizing altered risk factors when identified preoperatively.
