Abstract

OBJECTIVE: To examine the incidence of perioperative complications after RC and assess their impact on 90-day postoperative mortality during the index stay and upon readmission.MATERIAL AND METHODS: A total of 57,553 bladder cancer patients (unweighted cohort: 9,137 patients) treated with RC at 360 hospitals in the United States between 2005 to 2013 within the Premier Healthcare Database were used for analysis. Ninety-day perioperative mortality was the primary outcomes. Multivariable regression was used to predict the probability of mortality; models were adjusted for patient, hospital, and surgical characteristics.RESULTS: An increase in the number of complications resulted in an increasing predicted probability of mortality with a precipitous increase if patients had =4 complications compared to one complication during hospitalization following RC (index stay) (1.0% to 9.7%, p<0.001) and during readmission (2.0% to 13.1%, p<0.001). A readmission complication nearly doubled the predicted probability of postoperative mortality as compared to an initial complication (3.9% vs. 7.4%, p <0.001). During the initial hospitalization cardiac (OR=3.1, 95% CI 1.9-5.1), pulmonary (OR=4.8, 95% CI 2.8-8.4), and renal (OR=3.6, 95% CI 2-6.7) related complications had the most significant impact on the odds of mortality across categories examined.CONCLUSIONS: The number and nature of complications have a distinct impact on mortality after RC. As complications increase, there is an associated increase in perioperative mortality. This article is protected by copyright. All rights reserved.
