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.
| Age > 80 | No |
|---|---|
| History of cancer | No |
| Chronic cardiopulmonary disease | No |
| Heart rate ≥ 110 | No |
| Systolic BP < 100 | No |
| SaO₂ < 90% | No |
→sPESI0
- Interpretation：Low risk (~1% 30-day mortality) — consider outpatient treatment.
| Age > 80 | Yes (+1) |
|---|---|
| History of cancer | Yes (+1) |
| Chronic cardiopulmonary disease | Yes (+1) |
| Heart rate ≥ 110 | Yes (+1) |
| Systolic BP < 100 | Yes (+1) |
| SaO₂ < 90% | Yes (+1) |
→sPESI6
- Interpretation：High risk (~10%) — not suitable for outpatient management.

When is Simplified PESI (PE 30-day Mortality) used?
Identify low-risk PE potentially suitable for outpatient treatment.
What are the key clinical points for Simplified PESI (PE 30-day Mortality)?

How is Simplified PESI (PE 30-day Mortality) calculated in practice? Can you show a worked example?
Inputs: Age > 80 No, History of cancer No, Chronic cardiopulmonary disease No, Heart rate ≥ 110 No, Systolic BP < 100 No, SaO₂ < 90% No → Result: sPESI 0（Interpretation: Low risk (~1% 30-day mortality) — consider outpatient treatment.） Inputs: Age > 80 Yes (+1), History of cancer Yes (+1), Chronic cardiopulmonary disease Yes (+1), Heart rate ≥ 110 Yes (+1), Systolic BP < 100 Yes (+1), SaO₂ < 90% Yes (+1) → Result: sPESI 6（Interpretation: High risk (~10%) — not suitable for outpatient management.）
