The Scientific Registry of Transplant Recipients

supports the ongoing evaluation of solid organ transplantation in the United States. SRTR designs and carries out data analyses and maintains two websites to disseminate organ transplant information.
This site is srtr.transplant.hrsa.gov. Here you will find the OPTN/SRTR Annual Data Report, which publishes organ transplant statistics and is produced each year by SRTR staff and staff of the national Organ Procurement and Transplantation Network (OPTN).

At www.srtr.org, you will find older (pre-2010) annual data reports, current and past reports on organ procurement organizations and transplant programs, and information for researchers (including information about SRTR data and statistical methods).

Both sites aim to inform transplant programs, organ procurement organizations, policy makers, transplant professionals, transplant recipients, organ donors and donor families, and the general public about the current state of solid organ transplantation in the US.

SRTR also helps facilitate transplant research by providing access to data for qualified researchers interested in studying various aspects of solid organ transplantation.
