Epidemiology and demographics of upper gastrointestinal bleeding: prevalence, incidence, and mortality

Abstract

Despite major advances in diagnosis, prevention, and treatment, nonvariceal upper gastrointestinal bleeding still is a serious problem in clinical practice. Current evidence indicates that most peptic ulcer bleeding-linked deaths are not a direct sequela of the bleeding ulcer itself. Instead, mortality derives from multiorgan failure, cardiopulmonary conditions, or terminal malignancy, suggesting that improving further current treatments for the bleeding ulcer may have a limited impact on mortality unless supportive therapies are developed for the global management of these patients.
