About
The Organ Procurement and Transplantation Network (OPTN) is a unique public-private partnership that links all professionals involved in the U.S. donation and transplantation system. Also crucial to the system are individuals who sign organ donor cards, people who comment on policy proposals and countless volunteers who support donation and transplantation, among many others.
A driving force of the OPTN is to improve the U.S. system so that more life-saving organs are available for
transplant. Patient safety is at the forefront of activities at transplant hospitals, organ procurement organizations (OPOs) and labs.
The OPTN acts through its Board of Directors and committees, who bring a wealth of commitment and technical knowledge to guide us. Committees address issues of concern in the transplant community. The board establishes and maintains transplant policies (operational rules) and bylaws (membership requirements) that govern the OPTN.
