qSOFA

Bedside screen for patients at risk of poor outcomes from sepsis

Indication

  • Bedside screen for patients at risk of poor outcomes from sepsis

Criteria

  • id: ams; label: Altered mental status (GCS <15); type: yesno; points: 1
  • id: rr; label: Respiratory rate ≥ 22; type: yesno; points: 1
  • id: sbp; label: Systolic BP ≤ 100; type: yesno; points: 1

Interpretation

  • function(score) { if (score <= 1) return { risk: score + '/3', tier: 'Low Risk', action: 'qSOFA <2. Low risk for poor outcome. Continue clinical assessment.', color: 'green' }; return { risk: score + '/3', tier: 'High Risk', action: 'qSOFA ≥2. Associated with ≥10% in-hospital mortality. Evaluate for organ dysfunction.', color: 'red' }; }

Clinical pearls

  • qSOFA ≥2 associated with ≥10% in-hospital mortality
  • NOT a diagnostic criterion for sepsis — it is a screening tool
  • In ED: SIRS criteria may still be more sensitive for early detection
  • Full SOFA score (6 components) is used for ICU prognostication
