Clinical tool
qSOFA
Bedside prompt for higher risk of poor outcome in suspected infection.
qSOFA
0/ 3
Lower risk by qSOFA
A score below 2 does not exclude sepsis. Continue to assess clinically if infection is suspected.
This score supports risk stratification and should be interpreted alongside the overall clinical context and current treatment guidance.
Score support, not a decision
What this calculates
Quick SOFA: one point each for respiratory rate of 22 or more, altered mentation and systolic blood pressure of 100 mmHg or less.
When to use it
At first assessment of a patient with suspected infection outside the ICU, to flag those at higher risk of a poor outcome.
How to interpret it
A score of 2 or more identifies higher risk of death or prolonged ICU stay. A lower score does not exclude sepsis.
Important limitations
- It is a prognostic prompt, not a diagnostic or screening test for sepsis.
- It is deliberately insensitive early in illness, so clinical concern should prompt action whatever the score.
- It does not replace local sepsis pathways or early warning scores.
For practising medics only. Clinical tools support judgement, they do not replace it. Always verify results against current guidelines and the patient in front of you.
