The US Renal Data System (USRDS) remains the largest and most comprehensive resource for those seeking detailed information, data, and trends on a wide variety of kidney disease topics covering both end-stage renal disease (ESRD) and earlier stages of chronic kidney disease (CKD). Supported by the National Institute of Diabetes and Digestive and Kidney Diseases (NIDDK) at the National Institutes of Health and the Centers for Medicare & Medicaid Services, the USRDS Coordinating Center has operated from the Kidney Epidemiology and Cost Center (KECC) at the University of Michigan, in partnership with Arbor Research Collaborative for Health, in Ann Arbor, Michigan, since 2014.
