Objective: Determine the incidence and identify factors associated with potentially avoidable hospital readmissions due to uncontrolled symptoms or minor complications after surgery for gynecologic cancers. Methods: Women who underwent major abdominal or pelvic surgery for a gynecologic malignancy between 2015 and 2017 were identified from the National Surgical Quality Improvement Program targeted hysterectomy dataset. Hospital readmissions within 30 days of surgery were categorized as indicated readmissions or potentially avoidable readmissions by three independent reviewers. Demographic, clinical, and operative covariates were evaluated to determine their association with type of readmission using bivariable tests and adjusted multinomial logistic regression models. Results: A total of 20,986 women were identified. 19,814 (94.4%) were not readmitted, 894 (4.3%) were indicated readmissions, and 278 (1.3%) were potentially avoidable readmissions. Among those readmitted, 24% were potentially avoidable readmissions. Presence of ascites, increasing length of stay, and discharge to facility were associated with an increased risk of indicated and potentially avoidable readmissions. Age < 60 years old (RR 1.4, 95%CI 1.1–1.8), BMI ≥ 30 (RR 1.7, 95%CI 1.3–2.3), history of abdominal/pelvic surgery (RR 1.6, 95%CI 1.2–2.1), cervical cancer (RR 2.1, 95%CI 1.4–3.1), and open surgery (RR 2.1, 95%CI 1.4–3.2) were associated with an increased risk of a potentially avoidable readmission but not with increased risk of an indicated readmission. Median time to readmission did not differ between the two readmission groups (indicated = 8 days; avoidable = 7 days; p = .72). Conclusions: Among women with gynecologic cancer, 24% of all unplanned readmissions were attributed to uncontrolled symptoms or minor complications that were potentially avoidable. Age <60 years old, history of previous abdominal/pelvic surgery, obesity, cervical cancer, and open surgery were associated with an increase in risk of a potentially avoidable readmission.
