Score   points 

A patient with a score of 0 has a minimal risk of needing an intervention like transfusion, endoscopy or surgery. These patients can be considered for an early discharge and outpatient management.

Any score higher than 0 has higher risk for needing a medical intervention in terms of transfusion, endoscopy, or surgery. Scores of 6 or more were associated with a greater than 50% risk of needing an intervention.

Advantages over Rockall score:

  1. Predicts the need for a hospital based intervention.
  2. Lack of subjective variables (e.g. severity of systemic diseases) and
  3. Lack of a need for OGD to complete the score.

However it is not as good as the Rockall score in predicting overall mortality.
