Methodology · worked example, guidelines & full notes
Calculable within the first 24 h (unlike Ranson).
When to use
Early severity assessment in acute pancreatitis.
How it works
1 point each: BUN > 25 mg/dL, impaired mental status, SIRS, age > 60, pleural effusion. ≥ 3 = high risk.
Key points
- Calculable within the first 24 h (unlike Ranson).
- ≥ 3 marks higher mortality and organ failure risk.
- Combine with revised Atlanta criteria and imaging.

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.
| BUN > 25 mg/dL | No |
|---|---|
| Impaired mental status (GCS < 15) | No |
| SIRS (≥ 2 criteria) | No |
| Age > 60 | No |
| Pleural effusion | No |
→BISAP0/5
- Mortality (approx.)：< 2%
- Interpretation：Lower risk.
| BUN > 25 mg/dL | Yes (+1) |
|---|---|
| Impaired mental status (GCS < 15) | Yes (+1) |
| SIRS (≥ 2 criteria) | Yes (+1) |
| Age > 60 | Yes (+1) |
| Pleural effusion | Yes (+1) |
→BISAP5/5
- Mortality (approx.)：~13–22%
- Interpretation：High risk — consider higher level of care.

FAQ
Frequently asked questions
- Does BISAP Score (Pancreatitis Severity) 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 BISAP Score (Pancreatitis Severity) calculated in practice? Can you show a worked example?
- Inputs: BUN > 25 mg/dL No, Impaired mental status (GCS < 15) No, SIRS (≥ 2 criteria) No, Age > 60 No, Pleural effusion No → Result: BISAP 0 /5（Mortality (approx.): < 2%, Interpretation: Lower risk.） Inputs: BUN > 25 mg/dL Yes (+1), Impaired mental status (GCS < 15) Yes (+1), SIRS (≥ 2 criteria) Yes (+1), Age > 60 Yes (+1), Pleural effusion Yes (+1) → Result: BISAP 5 /5（Mortality (approx.): ~13–22%, Interpretation: High risk — consider higher level of care.）
