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.

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.）
