Making lung distribution fair and equitable
In its continued drive toward increasing equity, the donation and transplant community has developed a more fair and flexible lung allocation system. On March 2, 2023, new policies will replace the current lung classification system.
Lungs are the first organ type to be allocated under this new framework, called continuous distribution. In continuous distribution of lungs, candidates will receive a composite allocation score, which means no single factor will determine a lung patient’s priority. Watch explanatory videos

Beginning Wednesday, September 28, 2022, lung transplant programs will be able to access a program-specific resource report in the Data Services Portal.
View candidates’ LAS data as of Jan. 20, 2023.
More than 80 transplant programs are participating in the project; a virtual option for the in-person kickoff event is available to the entire community.
The OPTN will host a webinar for transplant patients to learn about upcoming changes to lung distribution.
How will patients benefit?
Simulation modeling suggests that the new policy is likely to improve key measures of the lung transplant system, including:
- Reducing patient deaths on the waiting list
- Increasing transplant rates for the sickest candidates
- Decreasing geographic variability in transplant rates
How did the community develop this policy?
The community was able to participate in the development of the policy through several public comment periods and online interactive values exercises. The methodology behind the exercises was a new way to collect community input early in the process.
Patients benefit from a more efficient system that gets the right organ to the right patient, at the right time.
