We compared the timing, causes, hospital costs and perioperative outcomes of index vs nonindex hospital readmissions after radical cystectomy.Materials and MethodsThe 2013 Nationwide Readmissions Database was queried for patients with bladder cancer undergoing cystectomy. Sociodemographic characteristics, hospital costs and causes of readmission were compared among index and nonindex readmitted patients. Univariable and multivariable logistic regression models were used to identify predictors of nonindex readmissions, mortality during the first readmission and subsequent readmission.ResultsAmong 4,991 patients identified 29% (1,447) and 11% (571) experienced an index and nonindex readmission, respectively. Compared to index readmissions, nonindex readmissions were more likely late readmissions (p <0.001) of older patients (p=0.047) who underwent cystectomy at higher volume hospitals (p=0.02) and were readmitted to hospitals located in less populated areas (p <0.001). Compared to index readmissions the percentage of nonindex readmissions for cardiovascular complications was higher (7.6% vs 2.9%, p=0.003), while the percentage of nonindex readmissions for gastrointestinal (6.0% vs 11.0%, p=0.04) and wound (5.3% vs 16.7%, p=0.0001) complications was lower. Predictors of nonindex readmission included longer length of stay (OR 1.02; 95% CI 1.001, 1.04), patient location in less populated areas, nonteaching hospital (OR 0.52; 95% CI 0.31, 0.86) and discharge to facility (OR 2.82; 95% CI 1.75, 4.55) or with home health (OR 1.49; 95% CI 1.05, 2.10). Nonindex readmissions had comparable mean readmission hospital costs ($14,147 vs $15,102, p=0.7), in-hospital mortality (OR 1.11; 95% CI 0.42, 2.87) and subsequent readmission (OR 1.32; 95% CI 0.87, 2.00) to index readmissions.ConclusionsThis nationally representative study of patients undergoing radical cystectomy demonstrated comparable perioperative outcomes and hospital costs between index and nonindex readmitted patients, which supports the continued regionalization of cystectomy care.
