About
The quick SOFA (qSOFA) score is a bedside screening tool for identifying patients with suspected infection who are at greater risk of poor outcomes outside the ICU. It uses three simple clinical criteria that can be assessed without laboratory tests. A qSOFA score ≥ 2 suggests the patient may have sepsis and should prompt further assessment with the full SOFA score and consideration of ICU-level care.
Formula
qSOFA = Sum of criteria met (0–3)
Positive if ≥ 2 criteria are present
Interpretation
| qSOFA Score | Interpretation |
|---|---|
| 0 – 1 | Low risk — not qSOFA positive |
| 2 – 3 | High risk — consider ICU level care |
