International prospective observational study of upper gastrointestinal haemorrhage: Does weekend admission affect outcome?

Introduction: Out of hours admissions have higher mortality for many conditions but upper gastrointestinal haemorrhage studies have produced variable outcomes.

Methods: Prospective study of 12 months consecutive admissions of upper gastrointestinal haemorrhage from four international high volume centres. Admission period (weekdays, weeknights or weekends), demographics, haemodynamic parameters, laboratory results, endoscopy findings, further procedures and 30-day mortality were recorded.
