Methodology · worked example, guidelines & full notes
Weights anaemia and renal disease heavily.
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.

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.
| Anaemia (Hb < 13 M / < 12 F g/dL) | No |
|---|---|
| Severe renal disease (eGFR < 30 or dialysis) | No |
| Age ≥ 75 years | No |
| Prior haemorrhage | No |
| Diagnosed hypertension | No |
→ATRIA0/10
- Bleeding risk：Low risk (< 1%/yr)
| Anaemia (Hb < 13 M / < 12 F g/dL) | Yes (+3) |
|---|---|
| Severe renal disease (eGFR < 30 or dialysis) | Yes (+3) |
| Age ≥ 75 years | Yes (+2) |
| Prior haemorrhage | Yes (+1) |
| Diagnosed hypertension | Yes (+1) |
→ATRIA10/10
- Bleeding risk：High risk (~5.8%/yr)

FAQ
Frequently asked questions
- What are the limits and cautions when using ATRIA Bleeding Score (AF)?
- For licensed clinicians and clinical researchers. Interpret results with history, investigations and local protocols; not a diagnosis or prescription, and not a substitute for multidisciplinary decision-making or local guidelines.
- Does ATRIA Bleeding Score (AF) upload patient data? Where is it calculated?
- Calculation runs locally in the browser; inputs and results are not uploaded. For licensed clinicians only; interpret with history, investigations and local protocols — not a diagnosis or prescription.
- How is ATRIA Bleeding Score (AF) calculated in practice? Can you show a worked example?
- Inputs: Anaemia (Hb < 13 M / < 12 F g/dL) No, Severe renal disease (eGFR < 30 or dialysis) No, Age ≥ 75 years No, Prior haemorrhage No, Diagnosed hypertension No → Result: ATRIA 0 /10（Bleeding risk: Low risk (< 1%/yr)） Inputs: Anaemia (Hb < 13 M / < 12 F g/dL) Yes (+3), Severe renal disease (eGFR < 30 or dialysis) Yes (+3), Age ≥ 75 years Yes (+2), Prior haemorrhage Yes (+1), Diagnosed hypertension Yes (+1) → Result: ATRIA 10 /10（Bleeding risk: High risk (~5.8%/yr)）
