Prior bleed = 2 points.
When to use

How it works
Hepatic/renal (1) + EtOH (1) + malignancy (1) + age >75 (1) + ↓platelets (1) + prior bleed (2) + uncontrolled HTN (1) + anemia (1) + genetic (1) + fall risk (1) + stroke (1). Range 0–12.
Key points
- Prior bleed = 2 points.
- 0–12 total.
- Next: HAS-BLED / ATRIA / CHA₂DS₂-VASc.

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.
| Hepatic or renal disease | No (0) |
|---|---|
| Ethanol abuse | No (0) |
| Malignancy | No (0) |
| Older age (> 75 y) | No (0) |
| Reduced platelet count or function | No (0) |
| Rebleeding risk (prior bleed) | No (0) |
| Hypertension (uncontrolled) | No (0) |
| Anemia | No (0) |
| Genetic factors (e.g. CYP2C9) | No / unknown (0) |
| Excessive fall risk | No (0) |
| Stroke history | No (0) |

FAQ
Frequently asked questions
- Does HEMORR₂HAGES Bleeding Risk Score 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 HEMORR₂HAGES Bleeding Risk Score calculated in practice? Can you show a worked example?
- Inputs: Hepatic or renal disease No (0), Ethanol abuse No (0), Malignancy No (0), Older age (> 75 y) No (0), Reduced platelet count or function No (0), Rebleeding risk (prior bleed) No (0), Hypertension (uncontrolled) No (0), Anemia No (0)… → Result: HEMORR₂HAGES 0 /12（Band: Low bleeding-risk band in derivation, Prior bleed weight: 2 points when present） Inputs: Hepatic or renal disease Yes (1), Ethanol abuse Yes (1), Malignancy Yes (1), Older age (> 75 y) Yes (1), Reduced platelet count or function Yes (1), Rebleeding risk (prior bleed) Yes (2), Hypertension (uncontrolled) Yes (1), Anemia Yes (1)… → Result: HEMORR₂HAGES 12 /12（Band: High bleeding-risk band, Prior bleed weight: 2 points when present）
