Abstract

Objective: To investigate the impact of continent urinary diversion on readmissions and hospital costs in a nationally representative sample of radical cystectomies (RCs) performed in the USA. Patients and Methods: The 2010-2014 Nationwide Readmissions Database was queried for patients with a diagnosis of bladder cancer who underwent RC. We identified patients undergoing continent (neobladder or continent cutaneous reservoir) or incontinent (ileal conduit) diversions. Multivariable logistic regression models were used to identify predictors of 90-day readmission, prolonged length of stay, and total hospital costs. Results: Amongst 21 126 patients identified, 19 437 (92.0%) underwent incontinent diversion and 1 689 (8.0%) had a continent diversion created. Continent diversion patients were younger, healthier, and treated at high-volume metropolitan centres. Continent diversions resulted in fewer in-hospital complications (37.3% vs 42.5%, P = 0.02) but led to more 90-day readmissions (46.5% vs 39.6%, P = 0.004). In addition, continent diversion patients were more often readmitted for infectious complications (38.7% vs 29.4%, P = 0.004) and genitourinary complications (18.5% vs 13.0%, P = 0.01). On multivariable logistic regression, patients with a continent diversion were more likely to be readmitted within 90 days (odds ratio [OR] 1.55, 95% confidence interval [CI]: 1.28, 1.88) and have increased hospital costs during initial hospitalisation (OR 1.99, 95% CI: 1.52, 2.61). Continent diversion led to a $4 617 (American dollars) increase in initial hospital costs ($36 640 vs $32 023, P < 0.001), which was maintained at 30 days ($48 621 vs $44 231, P < 0.001) and at 90 days ($56 380 vs $52 820, P < 0.001). Conclusion: In a nationally representative sample of RCs performed in the USA, continent urinary diversion led to more frequent readmissions and increased hospital costs. Interventions designed to address specific outpatient issues with continent diversions can potentially lead to a significant decrease in readmissions and associated hospital costs.
