(1) To quantify temporal changes in HFDs among lung transplant recipients.
(2) To determine the impact of May 2005 and November 2017 lung allocation score policy changes on HFDs in older relative to younger lung transplant recipients.


Changes in US lung allocation policies in 2005 and 2017 increased transplants among the sickest and oldest candidates on the waitlist. The impacts of these policy changes on health care utilization and quality of life are not known. Assessing hospital-free days (HFDs) among transplant recipients will provide a better assessment of the post-transplant survivorship experience than simple measures of mortality.
