Glasgow-Blatchford Bleeding Score
Background
- Glasgow-Blatchford Bleeding Score (SBS) Screening tool to assess the likelihood that a patient with an acute upper gastrointestinal bleeding will need medical intervention (i.e. blood transfusion and/or endoscopy)[1]
- May be able to identify patients who do not need to be admitted to hospital with upper gastrointestinal bleeding
- 16% of patients presenting with upper gastrointestinal bleeding had a GBS score of "0", considered low. Among these patients there were no deaths or interventions needed and the patients were able to be effectively treated in an outpatient setting[2]
Criteria

|---|---|
| Blood Urea | |
| ≥6·5 <8·0 (18-22.4mg/dL) | 2 |
| ≥8·0 <10·0 (22.4-28mg/dL) | 3 |
| ≥10·0 <25·0 (28-70mg/dL) | 4 |
| ≥25 (≥70mg/dL) | 6 |
| Hemoglobin (g/L) for men | |
| ≥12.0 <13.0 | 1 |
| ≥10.0 <12.0 | 3 |
| <10.0 | 6 |
| Hemoglobin (g/L) for women | |
| ≥10.0 <12.0 | 1 |
| <10.0 | 6 |
| Systolic blood pressure (mm Hg) | |
| 100–109 | 1 |
| 90–99 | 2 |
| <90 | 3 |
| Other markers | |
| Pulse ≥100 (per min) | 1 |
| Presentation with melaena | 1 |
| Presentation with syncope | 2 |
| Hepatic disease | 2 |
| Cardiac failure | 2 |
In the validation group, scores of 6 or more were associated with a greater than 50% risk of needing an intervention.
