Objective  To review the adverse event of hysterectomy caused by postoperative infection after cesarean section, formulate prevention and control strategies in combination with risk assessment tools, promote the standardization of perioperative management, reduce the medical burden on pregnant women, and improve patient satisfaction. Methods  The two adverse events of hysterectomy caused by postoperative infection after cesarean section that occurred in the obstetrics ward between October and November 2024 were selected as the research objects. A root cause analysis and risk assessment team composed of personnel from multiple departments was established. Through interviews, observations, and data review, the potential failure modes and causes were sorted out. The risk priority number (RPN) was calculated to determine the high-risk factors. Improvement strategies were formulated and implemented. After two-month implementation, the RPN scores and the compliance of various measures before and after the implementation were compared. Results  Before the improvement, the total RPN of the healthcare failure mode and effects analysis was 367.8. When rechecked in January 2025, the total RPN after the improvement dropped to 105.7, and no serious adverse events occurred again. The compliance and passing rates of various operations significantly increased: the intervention rate for maternal malnutrition rose from 17.5% to 48.6%, the passing rate of appropriate timing for prophylactic use of antimicrobial agents before surgery increased from 50.5% to 81.0%, the compliance rate of scrubbing the vagina with disinfectant before surgery increased from 15.0% to 60.0%, the implementation rate of standardized skin disinfection during surgery rose from 66.7% to 95.2%, the passing rate of aseptic techniques and hand hygiene operations during surgery increased from 75.0% to 95.2%, and the timely submission rate of specimens from infected patients increased from 29.4% to 47.6%, and all these differences were statistically significant (P<0.05). Conclusion  The combination of healthcare failure mode and effect analysis and root cause analysis can effectively improve adverse events during the perioperative period, optimize the perioperative management of cesarean section, and reduce the risk of infection.
