🩸 ATRIA Bleeding Score (AF)
Predict warfarin-associated haemorrhage in atrial fibrillation with the ATRIA score.
ATRIA Bleeding Score (AF)
Anaemia (Hb < 13 M / < 12 F g/dL)
Severe renal disease (eGFR < 30 or dialysis)
Age ≥ 75 years
Prior haemorrhage
Diagnosed hypertension
When to use
Quantify major bleeding risk on anticoagulation.
How it works
Anaemia (3), severe renal disease (3), age ≥ 75 (2), prior haemorrhage (1), hypertension (1). 0–3 low, 4 intermediate, 5–10 high.
Key points
- Weights anaemia and renal disease heavily.
- Supports shared decision-making.
- Targets modifiable risks rather than contraindicating therapy.
