Incidence of and mortality from acute upper gastrointestinal haemorrhage in the United Kingdom. Steering Committee and members of the National Audit of Acute Upper Gastrointestinal Haemorrhage.

OBJECTIVE: To describe the current epidemiology of acute upper gastrointestinal haemorrhage. DESIGN: Population based, unselected, multicentre, prospective survey. SETTING: 74 hospitals receiving emergency admissions in four health regions in the United Kingdom. SUBJECTS: 4185 cases of acute upper gastrointestinal haemorrhage in which patients were aged over 16 years identified over four months. OUTCOME MEASURES: Incidence and mortality. RESULTS: The overall incidence of acute upper gastrointestinal haemorrhage in the United Kingdom is 103/100,000 adults per year. The incidence rises from 23 in those aged under 30 to 485 in those aged over 75. At all ages incidence in men was more than double that in women except in elderly patients. 14% of the haemorrhages occurred in inpatients already in hospital for some other reason. In 27% of cases (37% female, 19% male) patients were aged over 80. Overall mortality was 14% (11% in emergency admissions and 33% in haemorrhage in inpatients). In the emergency admissions, 65% of deaths in those aged under 80 were associated with malignancy or organ failure at presentation. Mortality for patients under 60 in the absence of malignancy or organ failure at presentation was 0.8%. CONCLUSIONS: The incidence of acute upper gastrointestinal haemorrhage is twice that previously reported in England and similar to that reported in Scotland. The incidence increases appreciably with age. Although the proportion of elderly patients continues to rise and mortality increases steeply with age, age standardised mortality is lower than in earlier studies. Deaths occurred almost exclusively in very old patients or those with severe comorbidity.
