Why are people on the donor list given a lung allocation score and which factor has been eliminated as a reason for a transplant?

Answer:

The Lung Allocation Score (LAS) is used to determine which patients would benefit most from a transplant based on medical urgency and predicted post-transplant survival. The score is calculated using clinical data like age, oxygen requirement, pulmonary function, and the distance a patient can walk in six minutes. This system was implemented so that the amount of time spent on the donor waiting list is no longer the primary factor used to determine who receives a transplant.
