PROJECT SUMMARY/ABSTRACT Among the 12,000 deceased organ donors yearly in the US, there are racial disparities that have persisted over decades, with the Black population most recently donating at 69% of the White population. Relatively lower organ donation rates among racial minorities not only contribute to the organ shortage but also contribute to racial disparities in waitlisted candidate’s access to transplantation, with some racial minorities having longer wait times owing to difficult matching. Historically, efforts to address racial disparities in deceased organ donation have examined inpatient medical facility deaths, using inpatient death counts to estimate the potential organ donor pool, to benchmark successful organ recovery, and to target interventions. While only individuals who die in an inpatient medical facility can have their organs recovered for transplantation, the focus on this highly selected population is limiting. Structural racism, a determinant of racial disparities in health, affects healthcare resource availability, with Black individuals being 40% less likely than White individuals to have a usual source of healthcare in racially segregated neighborhoods. To date, healthcare resource availability has not been examined as a potential mediator of racial and geographic disparities in deceased organ donation. To better understand the impact of structural racism on deceased donor rates, we will perform novel linkages with three nationally representative datasets (Scientific Registry of Transplant Recipients, CDC WONDER, and National Health and Nutrition Examination Survey) to study the following aims: (1) To examine county-level risk factors for inpatient and outpatient death under medical conditions consistent with organ donation; (2) To examine the relationship between structural racism and the potential organ donor rate; and (3) To examine whether healthcare access mediates the relationship between structural racism and the potential organ donor rate. We hypothesize that structural racism affects inpatient facility death distribution, and subsequent organ donation rates, through its differential effects on healthcare access according to race and across geographies. If the proposed aims are achieved, we will directly inform national healthcare access and organ allocation policy, and population-level structural interventions to eliminate racial disparities in transplantation.

项目总结/摘要 在美国每年12，000名已故器官捐赠者中，种族差异一直存在 几十年来，黑人人口最近捐赠的白色人口的69%。相对 少数民族器官捐献率较低不仅导致器官短缺， 等待名单上的候选人获得移植的种族差异，一些少数民族有更长的时间 由于匹配困难，等待时间很长。 从历史上看，解决死者器官捐赠中种族差异的努力已经审查了住院医疗 设施死亡，使用住院死亡计数来估计潜在的器官供体库，以基准 成功的器官回收，并有针对性的干预措施。虽然只有在住院医疗中死亡的人 设施可以有他们的器官回收移植，重点是这个高度选择的人口是 限制。结构性种族主义是健康方面种族差异的一个决定因素，影响着医疗资源的可用性， 黑人比白色人获得常规医疗保健来源的可能性低40%， 种族隔离的社区到目前为止，医疗资源的可用性还没有作为一个 死者器官捐赠中种族和地理差异的潜在中介。 为了更好地了解结构性种族主义对已故捐赠者比率的影响，我们将进行新的联系， 有三个全国代表性的数据集（移植接受者科学登记处，CDC WONDER， 国家健康和营养检查调查），研究以下目标：（1）检查县级风险 在符合器官捐献的医疗条件下住院和门诊死亡的因素;（2） 研究结构性种族主义与潜在器官捐献率之间的关系;（3）研究 医疗服务是否会调节结构性种族主义与潜在器官捐赠者之间的关系 率 我们假设，结构性种族主义影响住院设施死亡分布，以及随后的器官 捐赠率，通过其对获得医疗保健的不同影响，根据种族和跨地域。 如果实现了拟议的目标，我们将直接告知国家医疗保健准入和器官分配 政策和人口层面的结构性干预措施，以消除移植中的种族差异。
