Characterizing the costs of complications after cystectomy: Can we target the primary drivers?

304Background: Radical Cystectomy (RC) is subject to substantial morbidity and patients face complication rates as high as 64% at 90-days. Understanding the costs of complications after RC is essential to improving care. We studied the financial cost of different categories of complications after RC in order to identify drivers of expenditures. Methods: Using the Premier Hospital Database we identified adult patients who underwent RC for bladder cancer from 600 hospitals across the US from 2003-2013. Ninety-day complications were captured using ICD9 codes. Complications were categorized according to Agency for Healthcare Research and Quality Clinical Classification Software. The primary outcome was cost of complication and secondary outcomes were mortality, length of stay (LOS), and discharge disposition. A generalized liner model conforming to a gamma distribution was used to evaluate cost data. Analyses were survey weighted, and all models were adjusted for patient (age, race, obesity, marital status, p...
