To perform a population-based study that evaluates contemporary racial disparities in the morbidity profile of patients undergoing radical nephrectomy in the United States.Using the Premier hospital database (Premier Inc, Charlotte, NC), which collects data from over 600 nonfederal hospitals throughout the United States, we identified patients undergoing a total nephrectomy as their primary procedure and also had a concurrent diagnosis of a kidney mass or cancer from 2003 to 2010. The primary outcome was 90-day major complication rates, based on the Clavien classification system. Multivariate logistic regression models were performed, adjusting for clustering by hospitals and survey weighting to ensure nationally representative estimates.The study population included 25,517 patients translating into a weighted sample of 185,135 radical nephrectomies. In a multivariate model including patient, hospital, and surgical characteristics, blacks were more commonly associated with a major complication (odds ratio, 2.1; P <.0001). When we incorporated Charlson comorbidity score into the model, the racial disparity in major complications was attenuated by 36% (odds ratio, 1.7; P <.0001). Adjusting for annual surgical volume in the multivariate model did not alter results.Our contemporary evaluation of patients undergoing radical nephrectomy in the United States demonstrates that blacks are associated with a markedly elevated rate of major complications as compared to whites. This disparity is possibly a result of unequal access to routine health care.
