Waitlist outcome differences for pulmonary hypertension patients are worse in the CAS era.

ABSTRACT:

Background

Patients with pulmonary hypertension (PH) have previously experienced worse waitlist outcomes than peers with other diagnoses. In 2021, the Lung Allocation Score (LAS) was revised to improve the prediction of expected survival. The Composite Allocation Score (CAS) was subsequently implemented in 2023. The effects of these changes on waitlist outcomes for patients with PH are not known.

Methods

A retrospective analysis of the United Network for Organ Sharing database was performed in 3 eras: LAS Era 1 (November 24, 2017-September 30, 2021), LAS Era 2 (October 1, 2021-March 8, 2023), and CAS Era (March 9, 2023-June 27, 2024). Unadjusted and adjusted competing risks regression analyzed waitlist outcomes within each era comparing diagnosis groups, and for PH patients
