⚠️ qSOFA Score Calculator
Calculate the quick SOFA (qSOFA) score to flag patients with suspected infection at risk of poor outcomes.
Clinical takeaway
qSOFA ≥ 2 warrants escalation and assessment for organ dysfunction.

When to use
Rapid bedside screen in suspected sepsis outside the ICU.
How it works
1 point each: respiratory rate ≥ 22, altered mentation (GCS < 15), systolic BP ≤ 100. ≥ 2 = higher risk.
Key points
- qSOFA ≥ 2 warrants escalation and assessment for organ dysfunction.
- A score < 2 does not exclude sepsis.
- It is a prompt, not a diagnosis.

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.
| Respiratory rate ≥ 22/min | No |
|---|---|
| Altered mentation (GCS < 15) | No |
| Systolic BP ≤ 100 mmHg | No |
→qSOFA0/3
- Interpretation：< 2: lower risk (does not rule out sepsis).
| Respiratory rate ≥ 22/min | Yes |
|---|---|
| Altered mentation (GCS < 15) | Yes |
| Systolic BP ≤ 100 mmHg | Yes |
→qSOFA3/3
- Interpretation：≥ 2: higher risk of mortality / prolonged ICU stay.

- Inputs: Respiratory rate ≥ 22/min No, Altered mentation (GCS < 15) No, Systolic BP ≤ 100 mmHg No → Result: qSOFA 0 /3（Interpretation: < 2: lower risk (does not rule out sepsis).） Inputs: Respiratory rate ≥ 22/min Yes, Altered mentation (GCS < 15) Yes, Systolic BP ≤ 100 mmHg Yes → Result: qSOFA 3 /3（Interpretation: ≥ 2: higher risk of mortality / prolonged ICU stay.）
