Single-center studies have demonstrated regional organ procurement collaboration to reduce travel redundancy and improve procurement efficiency. We studied deceased donor kidney, liver, and pancreas transplants performed in the United States between 2002 and 2014 using the Scientific Registry of Transplant Recipients (SRTR). We compared graft failure (GF), death-censored graft failure (DCGF), and patient death (PD) between organs procured by surgeons from the recipient's center (transplant procurement team [TPT]) versus surgeons from a different center (NTPT). Primary nonfunction (PNF) was assessed for liver and kidney and delayed graft function (DGF) for kidney using mixed-effects logistic modeling. There were 64 906 liver (61.6% TPT), 118 152 kidney (26.1% TPT), 10 832 simultaneous pancreas kidney (SPK; 56.6% TPT), and 4378 solitary pancreas (SP; 34.0% TPT) transplants. When compared to NTPT, DCGF for organs procured by TPT was significantly less for liver (adjusted HR: 0.93; 95% CI: 0.88-0.98) and marginally significant for kidney (0.97; 0.93-1.00) and SPK (0.90; 0.82-1.00), and not significant for SP (0.98; 0.86 -1.11). DGF for TPT kidney was significantly lower (adjusted OR 0.91; 0.87-0.95). Albeit modest, our findings demonstrate a difference between locally procured organs and those procured by the implanting team. Elucidating the etiology of these differences will enhance regional organ procurement collaboration.
单中心研究表明,区域器官获取合作可以减少旅行冗余并提高获取效率。我们使用移植受者登记处 (SRTR) 研究了 2002 年至 2014 年期间在美国进行的已故供者肾、肝和胰腺移植。我们比较了从受者中心(移植获取团队 [TPT])的外科医生获取的器官与从不同中心的外科医生获取的器官(非 TPT)之间的移植物失败 (GF)、受死亡限制的移植物失败 (DCGF) 和患者死亡 (PD)。使用混合效应逻辑模型评估了原发性无功能 (PNF) 对肝和肾,以及延迟移植物功能 (DGF) 对肾。共有 64606 例肝 (61.6% TPT)、118152 例肾 (26.1% TPT)、10832 例同时胰腺肾 (SPK; 56.6% TPT) 和 4378 例单独胰腺 (SP; 34.0% TPT) 移植。与 NTPT 相比,TPT 获取的器官的 DCGF 对于肝显著降低(调整后的 HR:0.93;95%CI:0.88-0.98),对于肾和 SPK 有边缘显著降低(0.97;0.93-1.00),对于 SP 则无显著差异(0.98;0.86-1.11)。TPT 肾的 DGF 显著降低(调整后的 OR 0.91;0.87-0.95)。尽管幅度不大,但我们的发现表明本地获取的器官与由植入团队获取的器官之间存在差异。阐明这些差异的病因将增强区域器官获取合作。
