🩸 Glasgow-Blatchford Score (Upper GI Bleed)
Risk-stratify upper GI bleeding with the Glasgow-Blatchford Score (GBS).
Glasgow-Blatchford Score (Upper GI Bleed)
Blood urea (mmol/L)
Haemoglobin (g/dL)
Sex
Systolic BP (mmHg)
Pulse ≥ 100
Melena
Syncope
Hepatic disease
Cardiac failure
When to use
Identify low-risk patients suitable for outpatient management before endoscopy.
How it works
Points from blood urea, haemoglobin (sex-specific), systolic BP, pulse ≥ 100, melena, syncope, hepatic disease and cardiac failure. Score 0 = very low risk.
Key points
- Uses only pre-endoscopy clinical and laboratory data.
- GBS 0 (some use ≤ 1) may allow outpatient management.
- Predicts need for transfusion, endoscopic therapy or surgery.
