Clinical tool
qSOFA
Bedside sepsis risk screen.
Score
0/ 3
Lower risk
qSOFA does not exclude sepsis. If infection is suspected, continue to assess clinically and reassess — a score below 2 should never be used to rule out a deteriorating patient.
qSOFA is a prognostic prompt, not a diagnostic test for sepsis and not a screening tool on its own. It was derived to identify patients with suspected infection at higher risk of poor outcome, and it is deliberately insensitive early — many patients who go on to deteriorate score 0 or 1 at first contact. Treat clinical concern as the trigger to act, whatever the score.
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.
