Upper gastrointestinal (GI) bleeding is one of the most common, high risk emergency disorders in the western world. Almost nothing has been reported on longer term prognosis following upper GI bleeding. The aim of this study was to establish mortality up to three years following hospital admission with upper GI bleeding and its relationship with aetiology, co-morbidities and socio-demographic factors.
Systematic record linkage of hospital inpatient and mortality data for 14 212 people in Wales, UK, hospitalised with upper GI bleeding between 1999 and 2004 with three year follow-up to 2007. The main outcome measures were mortality rates, standardised mortality ratios (SMRs) and relative survival.
Mortality at three years was 36.7% overall, based on 5215 fatalities. It was highest for upper GI malignancy (95% died within three years) and varices (52%). Compared with the general population, mortality was increased 27-fold during the first month after admission. It fell to 4.3 by month four, but remained significantly elevated during every month throughout the three years following admission. The most important independent prognostic predictors of mortality at three years were older age (mortality increased 53 fold for people aged 85 years and over compared with those under 40 years); oesophageal and gastric/duodenal malignancy (48 and 32 respectively) and gastric varices aetiologies (2.8) when compared with other bleeds; non-upper GI malignancy, liver disease and renal failure co-morbidities (15, 7.9 and 3.9); social deprivation (29% increase for quintile V vs I); incident bleeds as an inpatient (31% vs admitted with bleeding) and male patients (25% vs female).
Our study shows a high late as well as early mortality for upper GI bleeding, with very poor longer term prognosis following bleeding due to malignancies and varices. Aetiologies with the worst prognosis were often associated with high levels of social deprivation.
上消化道(GI)出血是西方世界最常见、风险最高的急症之一。几乎没有关于上消化道出血后长期预后的报道。本研究旨在确定上消化道出血住院患者在 3 年内的死亡率,并探讨其与病因、合并症和社会人口因素的关系。
对英国威尔士 1999 年至 2004 年间因上消化道出血住院的 14212 人的住院和死亡数据进行系统记录链接,并对 2007 年进行了 3 年的随访。主要结局指标为死亡率、标准化死亡率比(SMR)和相对生存率。
总体而言,3 年死亡率为 36.7%,有 5215 人死亡。上消化道恶性肿瘤(95%在三年内死亡)和静脉曲张(52%)的死亡率最高。与普通人群相比,入院后第一个月的死亡率增加了 27 倍。到第四个月降至 4.3,但在入院后 3 年内的每个月仍显著升高。3 年内死亡率的最重要独立预后预测因素是年龄较大(与 40 岁以下人群相比,85 岁及以上人群的死亡率增加了 53 倍);食管和胃/十二指肠恶性肿瘤(分别为 48 和 32)和胃静脉曲张病因(2.8)与其他出血相比;非上消化道恶性肿瘤、肝病和肾衰竭合并症(15、7.9 和 3.9);社会贫困(五分之一比第一分之一增加 29%);住院期间发生的出血(31%比因出血而入院)和男性患者(25%比女性)。
我们的研究表明,上消化道出血的晚期和早期死亡率都很高,由于恶性肿瘤和静脉曲张引起的出血后预后非常差。预后最差的病因通常与较高的社会贫困水平有关。
