Continuous distribution

Current status

The OPTN currently seeks public feedback to inform the development of a lung allocation policy based on a continuous distribution framework. To provide your input, read the information and instructions on the OPTN public comment page.

Continuous distribution

Organs can be distributed to candidates using a statistical formula that combines important clinical factors, such as medical urgency and post-transplant survival, along with proximity to the donor location. Using this approach, all candidates would receive a composite allocation score, but there would be no absolute geographic boundary. Candidates who receive the highest score based on their combination of factors receive highest priority.

Additional information is available on the OPTN continuous distribution initiative page.
