Clinical takeaway

Uses only pre-endoscopy clinical and laboratory data.

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.

Worked calculation

The values below come from this tool's own example placeholders and are computed server-side with the formula shown on this page, so the arithmetic can be checked quickly. It demonstrates how to substitute values only — it is not clinical advice and not a real case.

Blood urea6 mmol/L
Haemoglobin13 g/dL
SexMale
Systolic BP120 mmHg
Pulse ≥ 100No
MelenaNo
SyncopeNo
Hepatic diseaseNo
Cardiac failureNo

→GBS0

  • Interpretation:Score 0 — very low risk; outpatient management may be considered.
