AIMS65 Score for Upper GI Bleeding Mortality

Predicts in-hospital mortality and need for ICU admission in upper GI bleeding. Simpler than Glasgow-Blatchford; uses 5 binary variables obtainable at triage.

Used in: Gastrointestinal Bleeding

Score interpretation

AIMS65 = 0 — Very Low Risk (0.3% mortality) 0

In-hospital mortality ~0.3%. Very low risk.

→ Safe for ward-level care. Early endoscopy within 24h. Consider same-day discharge after endoscopy in selected low-risk patients.

AIMS65 = 1 — Low Risk (0.9% mortality) 1

In-hospital mortality ~0.9%. Low risk.

→ Admit. Oral PPI. Urgent inpatient endoscopy within 24h.

AIMS65 = 2 — Moderate Risk (6.4% mortality) 2

In-hospital mortality ~6.4%.

→ Admit. IV PPI (omeprazole 80mg bolus then 8mg/h). Endoscopy within 12–24h. GI consult.

AIMS65 = 3 — High Risk (13.1% mortality) 3

In-hospital mortality ~13.1%.

→ HDU/ICU. IV PPI infusion. Urgent endoscopy. Transfuse if Hb < 70 g/L. GI + surgical on call.

AIMS65 4–5 — Very High Risk (>20% mortality) 4–5

In-hospital mortality >20%. Very high risk.

→ ICU admission. Emergency endoscopy. Interventional radiology / surgical standby. Blood products. Early palliative involvement if appropriate.
