Background:We sought to investigate temporal trends in patient characteristics, waitlist, and posttransplant outcomes after heart transplantation in the United States.Methods:Using data from the United Network of Organ Sharing, we identified adults listed for heart transplantation between 1991 and 2019. Patients were divided into 4 eras based on the 3 time points in which changes were made to the patient selection/allocation policy (Era 1=January 1991–January 1999; Era 2=January 1999–July 2006; Era 3=July 2006–October 2018; and Era 4=October 2018–March 2020), and patient characteristics, waitlist, and posttransplant outcomes were evaluated for each era.Results:Between 1991 and 2019, 95 179 patients were added to the heart transplantation waitlist. Compared with Era 1, patients listed in Era 4 were older (mean age: 50 versus 52 years) and with higher risk comorbidities (eg, 10% versus 28.8% diabetes, 23.3% versus 35.6% obese). Over the study period, 22 738 patients died or were permanently delisted for deterioration on the waitlist while 61 687 were transplanted. Compared with the preceding era, there was significant decrease in death or deterioration in the last 2 eras (sub-hazard ratio, 0.67 [95% CI, 0.65–0.70] for Era 3 versus Era 2 and sub-hazard ratio, 0.65 [95% CI, 0.58–0.73] for Era 4 versus 3). Across the years, 27.1% to 40.5% of those on the waitlist were transplanted. Among those transplanted, there was increase in the rates of in-hospital stroke (2.8% in Era 1 to 3.7% in Era 4), renal failure requiring dialysis (7.2%–17.1%), and length-of-stay (14–17days), P<0.001. However, this did not negatively impact short-term survival when compared with the preceding era (1-year graft survival from Era 1 to Era 4=84.1%, 86.4%, 90.4%, and 89.7%, respectively).Conclusions:There have been significant changes in the characteristics of patients listed for heart transplantation. Although transplant volume has increased, the wide supply-demand gap persisted. The last two changes in the allocation policy achieved their primary objective of reducing waitlist mortality.

美国心脏移植后人口统计学、候补名单的时间趋势和移植后结果的变化:1991-2019 年 UNOS 数据库分析

背景:我们试图调查美国心脏移植后患者特征、候补名单和移植后结果的时间趋势。方法:使用来自器官共享联合网络的数据,我们确定了 1991 年至 2019 年期间列入心脏移植名单的成年人。根据对患者选择/分配政策进行更改的 3 个时间点(Era 1 = 1991 年 1 月 - 1999 年 1 月;Era 2 = 1999 年 1 月 - 2006 年 7 月;Era 3 = 2006 年 7 月 - 2018 年 10 月)分为 4 个时期;和 Era 4=2018 年 10 月-2020 年 3 月),并评估每个时代的患者特征、等候名单和移植后结果。结果:1991 年至 2019 年,95179 名患者被添加到心脏移植候补名单中。与 Era 1 相比,Era 4 中列出的患者年龄更大(平均年龄:50 岁与 52 岁)和更高风险的合并症(例如,10% 与 28.8% 的糖尿病,23.3% 与 35.6% 的肥胖)。在研究期间,有 22 738 名患者死亡或因病情恶化而被永久除名,而 61 687 名患者接受了移植。与前一个时代相比,最近 2 个时代的死亡或恶化显着减少(Era 3 与 Era 2 的亚风险比,0.67 [95% CI,0.65-0.70] 和亚风险比,0.65 [95 % CI, 0.58–0.73] 时代 4 对比 3)。多年来,候补名单上的人中有 27.1% 至 40.5% 被移植。在移植患者中,院内卒中发生率(Era 1 的 2.8% 至 Era 4 的 3.7%)、需要透析的肾功能衰竭(7.2%–17.1%)和住院时间(14– 17 天),在研究期间,有 22 738 名患者死亡或因病情恶化而被永久除名,而 61 687 名患者接受了移植。与前一个时代相比,最近 2 个时代的死亡或恶化显着减少(Era 3 与 Era 2 的亚风险比,0.67 [95% CI,0.65-0.70] 和亚风险比,0.65 [95 % CI, 0.58–0.73] 时代 4 对比 3)。多年来,候补名单上的人中有 27.1% 至 40.5% 被移植。在移植患者中,院内卒中发生率(Era 1 的 2.8% 至 Era 4 的 3.7%)、需要透析的肾功能衰竭(7.2%–17.1%)和住院时间(14– 17 天),在研究期间,有 22 738 名患者死亡或因病情恶化而被永久除名,而 61 687 名患者接受了移植。与前一个时代相比,最近 2 个时代的死亡或恶化显着减少(Era 3 与 Era 2 的亚风险比,0.67 [95% CI,0.65-0.70] 和亚风险比,0.65 [95 % CI, 0.58–0.73] 时代 4 对比 3)。多年来,候补名单上的人中有 27.1% 至 40.5% 被移植。在移植患者中,院内卒中发生率(Era 1 的 2.8% 至 Era 4 的 3.7%)、需要透析的肾功能衰竭(7.2%–17.1%)和住院时间(14– 17 天),最近 2 个时代的死亡或恶化显着减少(Era 3 与 Era 2 的亚风险比,0.67 [95% CI,0.65-0.70] 和亚风险比,0.65 [95% CI,0.58-0.73] ] 时代 4 对 3)。多年来,候补名单上的人中有 27.1% 至 40.5% 被移植。在移植患者中,院内卒中发生率(Era 1 的 2.8% 至 Era 4 的 3.7%)、需要透析的肾功能衰竭(7.2%–17.1%)和住院时间(14– 17 天),最近 2 个时代的死亡或恶化显着减少(Era 3 与 Era 2 的亚风险比,0.67 [95% CI,0.65-0.70] 和亚风险比,0.65 [95% CI,0.58-0.73] ] 时代 4 对 3)。多年来,候补名单上的人中有 27.1% 至 40.5% 被移植。在移植患者中,院内卒中发生率(Era 1 的 2.8% 至 Era 4 的 3.7%)、需要透析的肾功能衰竭(7.2%–17.1%)和住院时间(14– 17 天),P <0.001。然而,与之前的时代相比,这并没有对短期存活率产生负面影响(从时代 1 到时代 4 的 1 年移植物存活率分别为 84.1%、86.4%、90.4% 和 89.7%)。结论:有心脏移植患者的特征发生了显着变化。尽管移植量有所增加,但供需缺口依然存在。分配政策的最后两项变化实现了降低候补名单死亡率的主要目标。
