Save even more lives

The U.S. has the highest performing donation and transplant system in the world. But as good as it is, it needs to get even better to support the more than 100,000 patients on the waiting list. Based on the input of experts in our field, UNOS is proposing a five-part package of reforms to drive improvements to save even more lives.


Holding OPOs and transplant hospitals accountable for their performance, and helping them to improve and save more lives, requires consistent, reliable and timely metrics.

To accurately measure OPO performance, we need consistent data collection practices that provide the level of clinical detail required to determine donor suitability, such as information about whether the patient died on a ventilator, the potential donor-transmitted disease risk and details of medical treatment provided shortly before death.


Automated donor referrals would provide an improved and timely data source as well as the opportunity to better understand donor potential. They would be based on clearly established criteria for the completeness of information and the clinical thresholds established by the OPO to report potential donors. This hospital-reported, patient-level data could be used to calculate a clear metric suitable to assess and improve OPO performance. Transmitted independently and directly from the donor hospitals’ electronic medical records, this data should provide sufficient clinical detail to assess if the conditions of a death were consistent with the potential for organ donation. Other stakeholders also have recommended calculating a performance metric using this more accurate data.


CMS has regulatory oversight over OPOs. CMS should require or encourage all donor hospitals to provide directly reported ventilated death data from hospitals’ electronic medical records, a highly accurate source of data for calculating donor potential. Further, OPOs and transplant programs should be evaluated on a dashboard of metrics that reflects multiple aspects of performance and allows us to identify performance improvement opportunities.

Did you know?

  • Only 1% of people die in a way that makes them medically eligible to donate their organs.
  • In order to donate, patients must die while on a ventilator and meet stringent criteria to prevent possible donor-disease transmission.

Benefits of improved metrics

  • Boosts the ability to hold OPOs and transplant hospitals accountable for their performance.
  • Strengthens the capacity of UNOS and CMS to drive performance improvement throughout the entire transplant system.
  • Focuses on independently collected, reliable data to identify improvement opportunities across all aspects of the system.
