The prognostic value of single and repeated ≥10% FEV declines for chronic lung allograft dysfunction.

There is a paucity of data reporting the positive and negative predictive values (PPV, NPV) of acute declines in lung function on chronic lung allograft dysfunction (CLAD). We sought to define the predictive ability of single or repeated forced expiratory volume in the first second (FEV) declines for at least 3 weeks on the development of CLAD or death by 1-year. We analyzed 340 subjects with at least 3 years of follow-up data from two lung transplant centers.

Factors associated with waitlist clinical deterioration among United States lung transplant recipients under the continuous distribution system.

Background: Lung continuous distribution (CD), implemented on March 9, 2023, changed the calculation and relative importance of medical urgency and post-transplant survival in prioritizing candidates for transplant. We aimed to identify factors associated with waitlist clinical deterioration and change in expected post-transplant survival from listing to transplant in the current system.

Methods: We used Organ Procurement and Transplantation Network (OPTN) data to conduct a retrospective study of 2,395 adult, lung-only transplant recipients added to the waiting list and transplanted between March 9, 2023 and March 8, 2024.

Lung Allocation Score Exceptions in Persons with Cystic Fibrosis Undergoing Lung Transplant.

Lung transplantation can extend the lives of individuals with advanced cystic fibrosis (CF). Until March 2023, the Lung Allocation Score (LAS) was used in the United States to determine transplant priority. Certain clinical events or attributes ("risk events") that are not included in the LAS (e.
