Abstract

Objective Inequalities in health are well recognized in cardiovascular disease and cancer, but in comparison, we have minimal understanding for upper gastrointestinal bleeding. Since furthering our understanding of such inequality signposts preventable disease, we investigated in detail the association between upper gastrointestinal bleeding and socioeconomic status.

Design Population-based cohort study.

Setting All English National Health Service hospitals.

Population English adult population, 1 January 2001 to 31 December 2007.

Exposure measures Deprivation scores defined according to quintiles of neighbourhood areas ranked by the Indices of Multiple Deprivation for England 2007.

Outcome measures Rates of all adult admissions coded with a primary diagnosis of upper gastrointestinal bleed were analysed by deprivation quintile and adjusted for age, sex, region and year using Poisson regression.

Results The annual hospitalization rate for non-variceal haemorrhage was 84.6 per 100 000 population (95% CI 83.5 to 84.1; n=237 145), and for variceal haemorrhage, it was 2.83 per 100 000 population (95% CI 2.87 to 2.99; n=8291). There was a twofold increase in the hospitalization rate ratio for non-variceal haemorrhage from the most deprived areas compared to the least deprived (2.00, 95% CI 1.98 to 2.03). The ratio for variceal haemorrhage was even more pronounced (2.49, 95% CI 2.32 to 2.67). Inequality increased over the study period (non-variceal p<0.0001, variceal p=0.0068), and adjusting for age and sex increased the disparity between deprived and affluent areas. Case fatality did not have a similar socioeconomic gradient.

Conclusion Both variceal and non-variceal haemorrhage hospitalization rates increased with deprivation, and there was a similar gradient in all areas of the country and in all age bands. The existence of such a steep gradient suggests that there are opportunities to reduce hospitalizations down to the low rates seen in the most affluent, and thus, there is the potential to prevent almost 10 000 admissions and over 1000 deaths a year.
