A prospective cohort study of patients presenting to the emergency department with upper gastrointestinal bleeding.

Background: Upper gastrointestinal (UGI) bleeding is a common presentation to the Emergency Department (ED), and is associated with re-bleeding and significant mortality. Although several studies have described etiology and outcome of UGI bleeding, few have been done in the EDs.

Materials And Methods: This prospective observational cohort study included all patients presenting with hematemesis or melena, between June 2016 and January 2017 to the ED.
