Universal screening of potential organ donors and recipients for severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) is now recommended prior to transplantation in the United States during the coronavirus disease 19 (COVID-19) pandemic. Challenges have included limited testing capacity, short windows of organ viability, brief lead time for notification of potential organ recipients, and the need to test lower respiratory donor specimens to optimize sensitivity. In an early U.S. epicenter of the outbreak, we designed and implemented a system to expedite this testing and the results here from the first 3 weeks. The process included a Laboratory Medicine designee for communication with organ recovery and transplant clinical staff, specialized sample labeling and handoff, and priority processing. Thirty-two organs recovered from 14 of 17 screened donors were transplanted vs 70 recovered from 23 donors during the same period in 2019. No pretransplant or organ donors tested positive for SARS-CoV-2. Median turnaround time from specimen receipt was 6.8 hours (donors), 6.5 hours (recipients): 4.5 hours faster than daily inpatient median. No organ recoveries or transplantations were disrupted by a lack of SARS-CoV-2 testing. Waitlist inactivations for COVID-19 precautions were reduced in our region. Systems that include specialized ordering pathways and adequate testing capacity can support continued organ transplantation, even in a SARS-CoV-2 hyperendemic area.
在美国,2019 冠状病毒病(COVID-19)大流行期间,建议在移植前对潜在的器官供体和受者进行严重急性呼吸综合征冠状病毒 2(SARS-CoV-2)的普遍筛查。面临的挑战包括检测能力有限、器官存活窗口期短、通知潜在器官受者的通知时间短暂,以及需要检测下呼吸道供体标本以提高检测敏感性。在美国疫情的早期中心,我们设计并实施了一个系统,以加快检测速度,以下是前 3 周的结果。该过程包括一个实验室医学指定人员与器官回收和移植临床工作人员进行沟通,专门的样本标记和交接,以及优先处理。从 17 名筛查供体中的 14 名中回收了 32 个器官进行移植,而 2019 年同期从 23 名供体中回收了 70 个器官。没有一个器官供体或受者在移植前检测到 SARS-CoV-2 呈阳性。从收到标本到完成检测的中位数时间为 6.8 小时(供体),6.5 小时(受者):比每日住院中位数快 4.5 小时。没有因缺乏 SARS-CoV-2 检测而中断器官回收或移植。由于 COVID-19 预防措施,我们地区的等待名单激活减少。包括专门的订购途径和足够检测能力的系统可以支持继续进行器官移植,即使在 SARS-CoV-2 高度流行的地区也是如此。
