• W2801369521 abstract "BackgroundConcern has been raised over inferior lung transplantation survival associated with traumatic brain injury (TBI) organ donors. Our purpose was to explore the relationship between TBI donors and lung transplantation survival in the lung allocation score (LAS) era.MethodsWe queried the United Network for Organ Sharing Scientific Registry of Transplant Recipients and identified all adult (≥18 years) lung transplantations performed from May 4, 2005, to December 31, 2015. Recipients were dichotomized based on donor cause of death, TBI versus non-TBI, propensity score across eight variables (final LAS, intensive care unit admission before transplantation, extracorporeal membrane oxygenation before transplantation, donor age 50 years or older, cytomegalovirus antibody recipient−/donor+, ischemia time, annual center transplantation volume, single versus double lung transplantation), and matched 1:1 without replacement. Our primary outcomes were survival at 1, 3, and 5 years by Kaplan-Meier method.ResultsA total of 17,610 patients underwent isolated lung transplantation over the study period at 75 different transplantation centers. TBI was the leading cause of death in the donor population: 47% of all donors. Propensity score matching generated 6,782 well-matched donor TBI versus non-TBI pairs (all covariate p > 0.2). Risk-adjusted survival was similar between recipients of TBI donors versus non-TBI donors at 1 year (86% versus 86%, log-rank p = 0.27), 3 years (68% versus 68%, log-rank p = 0.47), and 5 years (55% versus 54%, log-rank p = 0.40).ConclusionsIn the largest analysis of TBI donors and the impact on lung transplantation survival to date, we found similar survival out to 5 years in lung transplant recipients of TBI versus non-TBI donors, alleviating concerns over continued transplantation with this unique donor population.
