Abstract
Objective: Prior to the introduction of a major change in the national allocation system for lung transplantation in 2005, African-Americans were less likely to receive lung transplants than Caucasians. While prior studies have shown that racial disparities have decreased in the post-policy era, no studies have re-examined racial disparities after accounting for differences in socioeconomic status, insurance status, and distance to transplant center. Additionally, no studies have identified whether or not there are regional variations in racial differences in transplant access.
Methods: We performed a retrospective cohort study on all candidates for lung transplantation waitlisted between May 4, 2005 and September 30, 2014. After performing all exclusions, our cohort included 19,162 subjects, whom we stratified by race and OPTN region. Multivariate regression was performed in order to determine the role of race in likelihood of transplantation within three years.
Results: There were no significant differences between mean times to transplantation or likelihood of transplantation within three years when comparing African-Americans and Caucasians on both a national and regional level.
Conclusions: No racial differences in likelihood of lung transplantation exist in any of the 11 OPTN regions. The current method of lung allocation provides an effective and objective way to allocate lungs in a way that limits racial disparities, even when adjusting for demographic factors, insurance status, and distance to transplant center.
