The survival benefits of liver transplantation for patients with end-stage liver disease are well established. In the United States, organ allocation is facilitated by 2 congressionally mandated organizations, the Organ Procurement and Transplantation Network, a contract held by the United Network for Organ Sharing (UNOS), and the Scientific Registry of Transplant Recipients (SRTR), a contract currently held by the Minneapolis Medical Research Foundation. The Organ Procurement and Transplantation Network/UNOS is responsible for operating the national network for organ procurement, organ allocation, and promotion of organ donation, while the SRTR provides the analytical support (eg, for organ allocation policy). Both seek input from the transplant community, and the Division of Transplantation within the Health Resources and Services Administration provides oversight.
