The volume of abdominal organ offers received by the Baylor Simmons Transplant Institute has increased over time, resulting in a higher workload for our donor call team. To quantify the increase in organ offers, determine the characteristics of these offers, and estimate the impact on our transplant center workload, we collected center-specific organ offer data from May 2019 to July 2021 using the UNOS Center Acceptance and Refusal Evaluation Report and performed a time study that collected the number of communications and time spent on communications for organ offers made during a typical week. The total offers per month increased by 140% (270/month to 648/month), while the number of transplanted organs remained stable. In addition, the percentage of offers for organs that were never transplanted increased from 54% to 75%. In a representative week-long time study, surgeons made 505, center coordinators 590, and answering service coordinators 318 distinct communications, averaging 3, 4, and 2 communications/hour. Between November 2019 and July 2021, offer-related workload increased by an estimated 97%. These results demonstrate a sizeable inefficiency in abdominal organ allocation associated with a nonrecoverable cost to our transplant center.

肝脏和肾脏分配的器官提供和工作量的单中心分析

随着时间的推移，贝勒西蒙斯移植研究所收到的腹部器官报价量不断增加，导致我们的捐赠者呼叫团队的工作量增加。为了量化器官报价的增加，确定这些报价的特征，并估计对我们移植中心工作量的影响，我们使用 UNOS 中心接受和拒绝评估报告收集了 2019 年 5 月至 2021 年 7 月特定中心的器官报价数据，并进行了一项时间研究，收集了在典型的一周内进行的器官提供的通信数量和通信时间。每月总offer增加了140%（270个/月到648个/月），而移植器官的数量保持稳定。此外，从未移植器官的报价百分比从 54% 增加到 75%。在一项为期一周的代表性研究中，外科医生进行了 505 次，中心协调员进行了 590 次，应答服务协调员进行了 318 次不同的通信，平均每小时 3、4 和 2 次通信。2019 年 11 月至 2021 年 7 月期间，与录取相关的工作量估计增加了 97%。这些结果表明，与我们移植中心不可收回的成本相关的腹部器官分配效率相当低下。
