SOFA & qSOFA Calculator

This tool helps clinicians rapidly assess risk of sepsis, organ dysfunction, and mortality using the qSOFA and SOFA scoring systems.

qSOFA (Quick SOFA)

Respiratory Rate ≥ 22/min Altered Mentation (GCS < 15) Systolic BP ≤ 100 mmHg

qSOFA Score: 0

Low risk

SOFA (Sequential Organ Failure Assessment)

Glasgow Coma Scale (GCS) Mean Arterial Pressure / Vasopressors PaO2/FiO2 Ratio Bilirubin (mg/dL) Platelets (x10⁹/L) Creatinine (mg/dL) or Urine Output

SOFA Score: 0

Low risk

Notes:

qSOFA ≥ 2 suggests high risk of sepsis and poor outcomes.
SOFA ≥ 2 indicates organ dysfunction; higher scores = higher mortality.
Always interpret scores in the context of clinical judgment.
