Purpose
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.

- Mortality [ Time Frame: 30 days ] [ Designated as safety issue: No ]Death from all causes 30 days from randomization
- Need for endoscopic therapy at index endoscopy [ Time Frame: At the time of index endoscopy ] [ Designated as safety issue: No ]To measure if endoscopic therapy is needed at the index endoscopy
- Need for transfusion [ Time Frame: Within 30days of randomization ] [ Designated as safety issue: No ]To measure if transfusion of blood products is needed within 30days of randomization
- Recurrent bleeding as defined [ Time Frame: Within 30days of randomization ] [ Designated as safety issue: No ]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 ] [ Designated as safety issue: No ]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 ] [ Designated as safety issue: No ]To measure if ICU admission is required at the index bleeding.
- Need for further endoscopic treatment [ Time Frame: Within 30days of randomization ] [ Designated as safety issue: No ]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 ] [ Designated as safety issue: No ]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 ] [ Designated as safety issue: No ]To measure recurrent bleeding in both study arms
- Rate of adverse events [ Time Frame: Within 30 days of randomization ] [ Designated as safety issue: No ]To measure the adverse events in either group, e.g. myocardial event, cerebrovascular event and acute renal failure.

Detailed Description:
The GBS, being a pre-endoscopy score with clinical parameters, is more suitable for patient triage leading to urgent endoscopy and a higher level of care. A GBS of 0 has been shown to identify patients with upper gastrointestinal bleeding who may be managed safely as outpatients. The proportion of patients requiring endoscopic therapy increases with a higher score. A cut-off score that identifies "high-risk" patients who may benefit from urgent intervention however has not been determined. Guidelines from Societies around the world recommend early endoscopy within 24 hours of presentation for AUGIB. The guidelines also state that a proportion of patients need emergency "out-of-hours" endoscopy, without defining the "high-risk" group. A recent international consensus on the management of NVUGIB recommended early endoscopy within 24 hours for NVUGIB, and noted no additional benefit associated with urgent endoscopy (<12 hours) vs. early endoscopy (>12 hours) in unselected patients with NVUGIB. However, there are only limited data on the role of urgent endoscopy in the "selected" subgroup of patients with high-risk NVUGIB.
