The new lung allocation policy has led to an increase in distant donors and consequently enhanced logistical burden of procuring organs. Though early single-center studies noted similar outcomes between same-team transplantation (ST, procuring team from transplanting center) and different-team transplantation (DT, procuring team from different center), the efficacy of DT in the contemporary era remains unclear. In this study, we evaluated the trend of DT, rate of transplanting both donor lungs, 1-year graft survival, and risk of Grade 3 primary graft dysfunction (PGD) using the Scientific Registry of Transplant Recipient (SRTR) database from 2006 to 2018. A total of 21619 patients (DT 2085, 9.7%) with 19837 donors were included. Utilization of DT decreased from 15.9% in 2006 to 8.5% in 2018. Proportions of two-lung donors were similar between the groups, and DT had similar 1-year graft survival as ST for both double (DT, HR 1.108, 95% CI 0.894-1.374) and single lung transplants (DT, HR 1.094, 95% CI 0.931-1.286). Risk of Grade 3 PGD was also similar between ST and DT. Given our results, expanding DT may be a feasible option for improving lung procurement efficiency in the current era, particularly in light of the COVID-19 pandemic.
新的肺分配政策导致了远距离供体的增加,从而增加了获取器官的后勤负担。尽管早期的单中心研究指出,同一团队移植(ST,来自移植中心的获取团队)和不同团队移植(DT,来自不同中心的获取团队)之间的结果相似,但在当代,DT 的疗效尚不清楚。在这项研究中,我们使用 2006 年至 2018 年的 Scientific Registry of Transplant Recipient(SRTR)数据库评估了 DT 的趋势、双肺移植的比率、1 年移植物存活率和 3 级原发性移植物功能障碍(PGD)的风险。共有 21619 名患者(DT 2085 例,9.7%)和 19837 名供体纳入研究。DT 的使用率从 2006 年的 15.9%下降到 2018 年的 8.5%。两组中双肺供体的比例相似,DT 的 1 年移植物存活率与 ST 相似,无论是双肺(DT,HR 1.108,95%CI 0.894-1.374)还是单肺移植(DT,HR 1.094,95%CI 0.931-1.286)。ST 和 DT 之间 3 级 PGD 的风险也相似。鉴于我们的结果,在当前时代,扩大 DT 可能是提高肺获取效率的可行选择,尤其是在 COVID-19 大流行的背景下。
