Scientific Registry of Transplant Recipients (SRTR)
The Scientific Registry of Transplant Recipients (SRTR) supports the ongoing evaluation of the scientific and clinical status of solid organ transplantation, including heart, lung, heart-lung, liver, kidney, pancreas, kidney-pancreas, and intestine. Through the data SRTR compiles, we can monitor and evaluate advances in transplant surgery techniques and organ preservation, improvements in matching donor organs with recipients, and developments in immunosuppressive therapies to reduce the size of the waiting list and improve transplant outcomes.
With oversight and funding from the Health Resources and Services Administration (HRSA), a division of the U.S. Department of Health and Human Resources (HHS), the SRTR is administered by the University Renal Research and Education Association (URREA), a non-profit health research organization in collaboration with the University of Michigan.
