Abstract: Objective To explore the effectiveness of failure mode and effect analysis in unplanned secondary surgery management. Method The management of unplanned secondary surgeries at the 926th Hospital of the Joint Logistics Support Force of the People’s Liberation Army of China from January 2021 to December 2022 was selected as the research object. Routine management was performed from January to December 2021 (as the control group), and failure mode and effect analysis was used to analyze the management of unplanned secondary surgeries in the control group. Preventive measures were implemented from January to December 2022 (as the observation group). Compare management results. Result In terms of the management effect of unplanned secondary surgery, the observation group had a significantly lower incidence of unplanned secondary surgery, postoperative bleeding rate, postoperative anastomotic fistula, and hospital stay days compared to the control group, and both groups had statistical significance (P<0.05). In terms of the quality of unplanned secondary surgery management, the observation group scored in the implementation of preventive measures, in postoperative management, and in surgical team communication situation, which were significantly better than the control group (P<0.05). The comparison between the two groups was statistically significant (P<0.05). Conclusion Failure mode and effect analysis was conducted in the management of unplanned secondary surgery, and it was found that the incidence of unplanned secondary surgery is influenced by various factors such as preoperative, intraoperative, and postoperative factors. In response to the influencing factors, measures such as strengthening staff management, emphasizing preoperative evaluation and preparation, and strengthening perioperative management can be taken to reduce the incidence of unplanned secondary surgery, postoperative bleeding, and anastomotic fistula, reduce surgical time and intraoperative blood transfusion, improve surgical safety and effectiveness, and enable patients to be discharged as soon as possible.

Key words: unplanned secondary surgery management, failure mode and effect analysis
