ABSTRACT Introduction Utilization of donation after circulatory death (DCD) donors in lung transplant in the United States lags when compared to other countries. We sought to evaluate geographical variation in the percentage of donation after circulatory death donors, conversion to lung transplant, agonal times, and consent for donation. Methods We queried the United Network for Organ Sharing database (2018–2023) to identify DCD donors and compared across organ procurement organizations (OPO). We illustrated the geographical variation in the location of transplant centers using DCDs, DCD donors used for solid organ transplant/ lung transplant, and median agonal time. Also, a special mapping was performed for the geographical difference of the refusal code utilization for declining the DCD lungs. Results There were 889 DCD donors where at least one lung was used for transplant, while 13,030 (75.6%) resulted in other solid organ transplants. The utilization of DCD organs was >65% and equal across the US, while DCD transplant centers were predominantly located in 5 states. The lower utilization of DCD lungs, up to 12.7% was equally observed in each state. Over 75%, of DCDs had an agonal time ≤ 30 min in most states except South Florida, eastern Pennsylvania and Colorado/Wyoming. The map colored based on the refusal code categories also showed the geographical differences. Conclusion As we continue to increase DCD lung utilization in the United States, better understanding of geographical barriers, adopting universal protocols in DCD organ donation and palliative care will hopefully lead to better utilization of organs from DCD donors, thereby increasing the number of transplants and decreasing organ wait times.
