Policy development process
We strive for consensus in developing policies for organ allocation and distribution. This collaborative process promotes equity among patients.
We want to hear from patients, professionals, donor families, transplant professionals, and anyone else interested in shaping transplant policy.
Find the OPTN Evaluation Plan, performance management and other tools here to ensure you are following policy correctly.
Organ Procurement and Transplantation Network (OPTN) policies are rules that govern operation of all UNOS member transplant hospitals, organ procurement organizations (OPOs) and histocompatibility labs in the U.S. Policies are made through a collaborative process involving committees, the OPTN Board of Directors and the public. View these policies now or view policy brochures.
Learn about the continuous distribution model approved by the OPTN as a framework for future policy development as it addresses geographic distribution of donated organs. Continuous distribution would, in the future, replace fixed geographic boundaries with a statistical model incorporating distance along with key clinical factors.
