The United States Renal Data System (USRDS) is a national data system that collects,
analyzes, and distributes information about chronic kidney disease (CKD) and end-stage renal disease (ESRD) in the United States.
The USRDS is funded directly by the National Institute of Diabetes
and Digestive and Kidney Diseases (NIDDK). USRDS staff collaborates with members
of Centers for Medicare & Medicaid Services (CMS), the United Network for Organ
Sharing (UNOS), and the ESRD networks, sharing datasets and actively working to
improve the accuracy of ESRD patient information.
