Enhanced recovery after surgery in elective benign general gynaecological surgery: postoperative recovery outcomes and health economic value of hospitalisation costs under China’s diagnosis-related group (DRG) payment system – a retrospective cohort study at a tertiary hospital

OBJECTIVE: The aim of this study was to explore the application of enhanced recovery after surgery (ERAS) in patients undergoing gynaecological surgery. This investigation included an analysis of the postoperative recovery curve and the factors that influenced the number of postoperative recovery days. This study also aimed to further investigate the impact of various factors on health economics. DESIGN, SETTING AND PARTICIPANTS: A retrospective cohort study was conducted in the Fourth Ward of the General Gynaecology Centre of the Peking Union Medical College Hospital. A total of 1000 patients who had undergone elective benign gynaecological surgery between July 2021 and December 2022 were included. Demographic, perioperative and other relevant data were collected, and a visual analogue scale (VAS) survey was conducted using the European Five-Dimensional Health Scale (EQ-5D). The factors that influenced the number of postoperative recovery days were analysed using a multivariate linear regression analysis. Additionally, patients who had undergone laparoscopic myomectomy, laparoscopic ovarian cystectomy, laparoscopic total hysterectomy, abdominal myomectomy and abdominal total hysterectomy were grouped based on whether their ERAS implementation rate was ≥70%. Our goal was to evaluate the health economic value of the diagnosis-related group (DRG) payments from multiple perspectives and provide actionable recommendations for health insurance bureaus, hospitals and patients from a multi-dimensional perspective. RESULTS: ERAS completion rates for measures such as avoiding preoperative sedation and early postoperative ambulation exceeded 95%, whereas rates for chewing gum and intraoperative temperature monitoring were
