Objective To investigate the causes and factors affecting unplanned reoperation,and to provide a reference basis for reducing the incidence of unplanned return of the patient to the operating room for reoperation.Methods Surgical data from the hospital was extracted spanning from January to December 2022,and subjected to a descriptive analysis of the overall situation,departmental distribution,primary reasons,and patient referrals related to unplanned reoperations in the hospital,and analyzed factors contributing to unplanned reoperations in the hospital using binary logistic regression.Results In 2022,130 unplanned reoperations were reported in this hospital,corresponding to an incidence of 0.35％.Patients who required unplanned reoperation were predominantly male(63.08％).The majority had surgical incision grade of category 0(46.92％),and surgeries were classified as levels 3 and 4(80.77％).Furthermore,88.46％of the surgeries were performed by surgeons with advanced degrees or higher.The common causes were postoperative bleeding,failure to achieve the desired result,need for the condition,probing for the cause,and occurrence of leakage or fistula,collectively accounting for 50.00％of the cases.Key factors contributing to unplanned reoperations were sex,type of surgical incision,and incision healing grade;among which male patients(OR=1.733,P=0.006),patients with class Ⅰ surgical incision(OR=2.909,P=0.004),and patients with incision grade B healing(OR=6.565,P＜0.001)showed a higher propensity for unplanned reoperations.Conclusion Hos-pitals should emphasize monitoring and managing unplanned reoperations by improving perioperative supervision,conducting thorough root cause analyses,and focusing on continuous quality improvement to enhance surgical outcomes and patient safety.
