Geography in organ distribution
System notice: Clarification of pre-existing liver disease implemented March 1
The OPTN has approved a continuous distribution model 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.
Organs can be distributed to candidates using a statistical formula that combines important clinical factors, such as medical urgency and likelihood of graft survival, along with proximity to the donor location. Using this approach, all candidates would receive a relative distribution score, but there would be no absolute geographic boundary. Candidates who best meet the combination of factors receive the highest priority.
