Quantify possible increases in cadaveric organ donation from intensive care units; identify major sources of regional variation.
Confidential audit of all deaths in intensive care units in England in 1989 and 1990 and in Wales in 1990.
15 regional and special health authorities in England; Wales.
24,023 audited deaths in England; 682 in Wales.
Solid organ and corneal donor rates per 100 deaths; solid organ donor rate per 100 confirmed brain stem deaths; regional variation in (a) whether brain stem death was possible diagnosis, (b) general medical contraindications to donation, (c) relatives' refusal.
Confirmed brain stem death accounted for 2389 (10%) audited deaths in England. In 438 (18%) there was a general medical contraindication to organ donation, and of 1829 (94%) families asked about donation, 557 (30%) refused. Data for England suggested that among potential donors the heart is suitable for transplantation in 65% of cases, the kidneys in 95%, the liver in 71%, the lungs in 31%, and the corneas in 92%. Reasons for any shortfall in achievement of transplantation varied with organ type. Solid organ and corneal donor rates per 100 deaths were 5.0 and 3.9 respectively in England and 4.3 and 2.1 respectively in Wales. The solid organ donor rate per 100 confirmed brain stem deaths was 50 in England and 41 in Wales.
A 20% increase in number of cadaveric kidney donors from intensive care could be achieved by prompt testing for brain stem death and a quarter reduction in relatives' refusals.
量化重症监护病房尸体器官捐献可能的增加量;确定地区差异的主要来源。
对1989年和1990年英格兰以及1990年威尔士重症监护病房的所有死亡病例进行保密审计。
英格兰的15个地区和特殊卫生当局;威尔士。
英格兰24,023例经审计的死亡病例;威尔士682例。
每100例死亡中的实体器官和角膜捐献率;每100例确诊脑干死亡中的实体器官捐献率;地区差异,包括(a)脑干死亡是否为可能的诊断,(b)器官捐献的一般医学禁忌证,(c)亲属拒绝。
确诊脑干死亡占英格兰2389例(10%)经审计的死亡病例。438例(18%)存在器官捐献的一般医学禁忌证,在1829例(94%)被询问器官捐献的家庭中,557例(30%)拒绝。英格兰的数据表明,在潜在捐献者中,心脏适合移植的比例为65%,肾脏为95%,肝脏为71%,肺为31%,角膜为92%。不同器官类型移植未达预期的原因各不相同。英格兰每100例死亡中的实体器官和角膜捐献率分别为5.0和3.9,威尔士分别为4.3和2.1。每100例确诊脑干死亡中的实体器官捐献率,英格兰为50,威尔士为41。
通过迅速检测脑干死亡以及将亲属拒绝率降低四分之一,重症监护病房尸体肾捐献者数量可增加20%。
