How evidence review works →Adults with atrial fibrillation undergoing bleeding-risk assessment in an anticoagulation care pathway.
Additive 0–9 point bleeding-risk factor score with renal and liver dysfunction, drug exposure, and alcohol counted separately.
Categorical point score only; thresholds are stated in the question text.
All nine separately counted factors, incomplete state, maximum score, and ≥3 boundary.

Limitations and exclusions
- Do not use the score alone to withhold anticoagulation.
- Definitions of renal/liver dysfunction, labile INR, drugs, and alcohol must match the original score or current validated implementation.
- Actively identify and modify reversible bleeding risks.
- A score is not a substitute for medication reconciliation or ongoing clinical surveillance.

About this tool
HAS-BLED Score Calculator
Use this HAS-BLED calculator to total the published bleeding-risk factors and keep potentially modifiable factors visible during review.
The score should flag review needs rather than serve as an automatic reason to withhold anticoagulation. Use current guidance and the complete patient context.
