qSOFA (Quick SOFA)

Bedside screen for patients with suspected infection who are at risk of a poor outcome from sepsis — no labs required.

For healthcare professionals.These calculate a score or a measurement from values you enter. They do not diagnose, and they are no substitute for clinical judgement. If you are a patient, discuss any result with your own doctor rather than acting on it.

Respiratory rate ≥ 22/min

Altered mentation (GCS < 15)

Systolic blood pressure ≤ 100 mmHg

A screening tool, not a diagnostic criterion for sepsis, and not intended to replace full SOFA scoring or clinical judgment in patients already in a monitored/ICU setting.
