Urgent vs. Early Endoscopy in High Risk Patients With Upper Gastrointestinal Bleeding (UGIB)
Acute upper gastrointestinal bleeding (UGIB) is one of the commonest medical emergencies. The condition accounts for 150 per 100,000 populations. A National United Kingdom reported a crude overall mortality rate of 10%. While bleeding stops spontaneously in majority of patients at their presentation, there remains a subgroup of patients who continue to bleed or develop recurrent bleeding. In these patients, the mortality increases manifolds. If these high-risk patients can be identified, early interventions may improve their outcomes.
Several prognostic indices are in use for the purpose of patient stratification. They include the Rockall, Glasgow-Blatchford (GBS) and the Baylor scores. The Rockall score is a composite score which incorporates clinical parameters as well as findings during endoscopy which was derived to predict mortality. The GBS is a pre-endoscopy or a clinical score for the prediction for the need of further intervention loosely defined as the need for transfusion, endoscopy or surgery. It has been shown to be accurate in identifying low risk patients for early discharge.

|Official Title:||Urgent vs. Early Endoscopy in High Risk Patients With UGIB|
- Mortality [ Time Frame: 30 days ]Death from all causes 30 days from randomization
- Need for endoscopic therapy at index endoscopy [ Time Frame: At the time of index endoscopy ]To measure if endoscopic therapy is needed at the index endoscopy
- Need for transfusion [ Time Frame: Within 30days of randomization ]To measure if transfusion of blood products is needed within 30days of randomization
- Recurrent bleeding as defined [ Time Frame: Within 30days of randomization ]To measure if any clinical or endoscopic recurrent bleeding is identified.
- Duration of hospital stay of index bleeding [ Time Frame: Within 30 days of randomization ]To measure the number of days of hospital stay upon randomization, only counted the hospitalization days of index bleeding.
- ICU stay [ Time Frame: Within 30days of randomization ]To measure if ICU admission is required at the index bleeding.
- Need for further endoscopic treatment [ Time Frame: Within 30days of randomization ]To measure if further endoscopic treatment if required at recurrent bleeding
- Emergency surgery or interventional radiology to achieve hemostasis [ Time Frame: Within 30days of randomization ]To measure if emergency surgery or interventional radiology is needed at index bleeding or recurrent bleeding to achieve hemostasis
- Rates of recurrent bleeding [ Time Frame: Within 30 days of randomization ]To measure recurrent bleeding in both study arms
- Rate of adverse events [ Time Frame: Within 30 days of randomization ]To measure the adverse events in either group, e.g. myocardial event, cerebrovascular event and acute renal failure.
