- W3217354483 abstract "Introduction: Due to discrepancies between donor supply and recipient demand, the cardiac transplantation process aims to prioritize the most medically urgent patients. It remains unknown how recipients with the lowest medical urgency compare to others in the allocation process. Methods: We performed a retrospective analysis of the United Network for Organ Sharing database. Patients listed for cardiac transplantation between January 2011 to May 2020 were stratified according to status at time of transplantation. Baseline recipient and donor characteristics, waitlist survival, and post-transplantation outcomes were compared between lower urgency listing and higher urgency listing in the years before and after the 2018 allocation system change. Results: Lower urgency patients in the old system were older (58.5 vs. 56 years) and more likely female (54.4% vs. 23.8%) compared to the highest urgency patients, and these trends persisted in the new system for the lowest urgency patients (59 vs. 55 years; 47.0% vs. 23.9% female; p<0.001, all). Donors for the lowest urgency patients were more likely older, female, or have a history of CMV, hepatitis C, or diabetes (p<0.01, all). The lowest urgency patients had longer waitlist times, and under the new allocation system these patients received organs from shorter distances and with decreased ischemic times (178 vs. 269 miles, 3.1 vs 3.5 hours; p<0,001, all). There was no difference in post-transplantation survival (p<0.01, all). Conclusions: Cardiac transplantation for lower urgency patients has not been well characterized. Our analysis demonstrates that, over the last decade, these patients receive hearts from donors with additional comorbidities compared to higher urgency patients but that outcomes are similar at one year. Our results may support the utility of early listing and less stringent thresholds for organ acceptance to increase access to cardiac transplantation." @default.
