How UNOS collects data

UNOS developed the online database system UNetSM to collect, store, analyze and publish all OPTN data that pertains to the patient waiting list, organ matching, and number of transplants performed. The OPTN has tracked every organ donation and transplant event occurring in the U.S. since Oct. 1, 1987. Learn more about the technology that powers transplants.

What do we do with this data?

UNOS research staff aggregate national OPTN data and analyze trends in transplantation, and make this data available to researchers, patients and the public at large. By tracking data at national, regional and individual institutional levels, UNOS researchers strive to:

  • develop strategies to drive improvement
  • continually refine transplantation policies to identify and address inequities in transplant
  • develop system tools to allow for more efficient donor and recipient matching
  • identify opportunities to increase the number of transplants
  • provide powerful research and data analytics to members in order to contribute to collective knowledge of effective organ transplantation
