Ku E, Yang W, McCulloch CE, et al. - In this retrospective cohort analysis, researchers investigated disparities in survival among dialysis patients by race, and tried to associate them with racial variations in comorbid conditions and rates of mortality in the setting of kidney disease not yet needing dialysis therapy. In CRIC, a total of 3,288 black and white participants were examined, none of whom were on dialysis at enrollment. A median follow-up of 7.1 years was performed. Starting from the time of dialysis commencement, lower risk for mortality was observed in blacks vs whites. Beginning from baseline CRIC enrollment, notably stronger strength of the link between some risk factors and dialysis was observed for whites vs blacks. In this study, blacks compared with whites, managed with dialysis, demonstrated an apparent survival benefit, which likely to be due to selected transition of a subset of whites with more severe comorbid conditions onto dialysis.
