Risk factors for immediate failure of outpatient surgery in gynecologic surgery

OBJECTIVE: To describe the risk factors for immediate failure of gynecologic outpatient surgery. The secondary objective was to describe the risk factors for rehospitalization within 30 days after surgery. METHODS: This is a single-center retrospective cohort study conducted on all patients operated on in outpatient surgery in gynecology at the Lille University Hospital. The primary outcome was defined as any unanticipated admission to the inpatient postoperative care unit on the day of the operation. The secondary outcome was defined as any rehospitalization within 30 days following the intervention. Our statistical analysis included 916 patients operated on between January and July 2019. RESULTS: In our study, 84 patients (9.2%) had an immediate failure of outpatient surgery. The most frequent etiologies were surgical (58.3%). In multivariate analysis with logistic regression, the following variables were associated with an increased risk of immediate failure of outpatient surgery: urogynecologic surgery (P < 0.001), complex laparoscopy (P = 0.004), endometriosis surgery (P < 0.001), and a duration of intervention longer than 1 hour (P < 0.001). CONCLUSION: We find an increased risk of immediate failure of gynecologic outpatient surgery depending on the type of surgery as well as for surgeries lasting more than 1 hour.
