Methodology · worked example, guidelines & full notes
Identifies modifiable contributors to bleeding.
When to use
Assess major bleeding risk and target modifiable factors.
How it works
Anaemia (2), age > 74 (1), bleeding history (2), eGFR < 60 (1), antiplatelet use (1). 0–2 low, 3 medium, 4–7 high.
Key points
- Identifies modifiable contributors to bleeding.
- Compares favourably with HAS-BLED in some cohorts.

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 low / Hct < 36% F, < 40% M) | No |
|---|---|
| Age > 74 years | No |
| Bleeding history | No |
| eGFR < 60 mL/min/1.73m² | No |
| Treatment with antiplatelet | No |
→ORBIT0/7
- Bleeding risk：Low (~2.4 per 100 pt-yr)
| Anaemia (Hb low / Hct < 36% F, < 40% M) | Yes (+2) |
|---|---|
| Age > 74 years | Yes (+1) |
| Bleeding history | Yes (+2) |
| eGFR < 60 mL/min/1.73m² | Yes (+1) |
| Treatment with antiplatelet | Yes (+1) |
→ORBIT7/7
- Bleeding risk：High (~8.1 per 100 pt-yr)

FAQ
Frequently asked questions
- What are the limits and cautions when using ORBIT 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 ORBIT 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 ORBIT Bleeding Score (AF) calculated in practice? Can you show a worked example?
- Inputs: Anaemia (Hb low / Hct < 36% F, < 40% M) No, Age > 74 years No, Bleeding history No, eGFR < 60 mL/min/1.73m² No, Treatment with antiplatelet No → Result: ORBIT 0 /7（Bleeding risk: Low (~2.4 per 100 pt-yr)） Inputs: Anaemia (Hb low / Hct < 36% F, < 40% M) Yes (+2), Age > 74 years Yes (+1), Bleeding history Yes (+2), eGFR < 60 mL/min/1.73m² Yes (+1), Treatment with antiplatelet Yes (+1) → Result: ORBIT 7 /7（Bleeding risk: High (~8.1 per 100 pt-yr)）
