Alimentary TractTime trends and outcome of gastrointestinal bleeding in the Veneto Region: A retrospective population based study from 2001 to 2010

BackgroundGastrointestinal bleeding is the most frequent emergency for gastroenterologists. Despite advances in management, an improvement in mortality is still not evident.AimDetermining time trends of gastrointestinal bleeding hospitalization and outcomes from 2001 to 2010 in the Veneto Region (Italy).Patients and methodsData of patients admitted with gastrointestinal bleeding from Veneto regional discharge records were retrospectively evaluated. Chi-squared and multivariate logistic regression model were used.ResultsOverall, 44,343 patients (mean age 64.2 ± 8.6 years) with gastrointestinal bleeding were analysed: 23,450 (52.9%) had upper, 13,800 (31.1%) lower, and 7093 (16%) undefined gastrointestinal bleeding. Admission rate decreased from 108.0 per 100,000 in 2001 to 80.7 in 2010, mainly owing to a decrease in upper gastrointestinal bleeding (64.4 to 35.9 per 100,000, p < 0.05). Reductions in hospital fatality rate (from 5.3% to 3%, p < 0.05), length of hospital stay (from 9.3 to 8.7 days, p < 0.05), and need for surgery (from 5.6% to 5%, p < 0.05) were observed. Surgery (OR: 2.97, 95% CI: 2.59-3.41) and undefined gastrointestinal bleeding (OR: 2.89, 95% CI: 2.62-3.19) were found to be risk factors for mortality.ConclusionsPatient admissions for gastrointestinal bleeding decreased significantly over the years, owing to a decrease in upper gastrointestinal bleeding. Improved outcomes could be related to regional dedicated clinical gastroenterological management.
