1City Clinical Hospital #40, Yekaterinburg, Russian Federation.
Aim:
To identify risk factors of adverse outcomes in patients with nonvariceal upper gastrointestinal bleeding.
Material And Methods:
Epidemiological observational analytical longitudinal retrospective cohort study included 312 patients who were hospitalized in the Clinical Hospital #40 of Yekaterinburg in 2014-2016. The main inclusion criterion was nonvariceal upper gastrointestinal bleeding.
Results:
In-hospital mortality was 31 (9.9%) of 312 patients. Multivariate analysis confirmed the following risk factors of mortality: severity of blood loss (OR 22.70, 95% CI 5.08-102.00); open surgery (OR 15.20, 95% CI 2.71-74.80); M. Charlson comorbidity index (OR 2.15, 95% CI 1.34-3.43); risk of recurrent bleeding according to T. Rockall scale (OR 1.76, 95% CI 1.18-2.64).
Conclusion:
Independent risk factors of adverse outcomes in patients with nonvariceal upper gastrointestinal bleeding are severe hemorrhagic shock, open surgery, high M. Charlson comorbidity index and risk of recurrent bleeding according to T. Rockall scale.
