Sequential Organ Failure Assessment (SOFA) Score

Predicts ICU mortality based on lab results and clinical data.

Welcome Sepsis-3 readers! We've also added the qSOFA Score with a summary of the new definitions and recommendations.

Use the worst value in a 24-hour period.

On mechanical ventilation

Including CPAP

Platelets, ×10³/µL

Glasgow Coma Scale

If on sedatives, estimate assumed GCS off sedatives

Bilirubin, mg/dL (μmol/L)

Mean arterial pressure OR administration of vasoactive agents required

Listed doses are in units of mcg/kg/min

Creatinine, mg/dL (μmol/L) (or urine output)

Management

Even though it is calculated sequentially based on the worst values in the past 24 hours, the SOFA Score is not meant to indicate the success or failure of interventions or to influence medical management.

Critical Actions
  • Clinical prediction tools such as the SOFA and APACHE II Scores can be measured on all patients admitted to the intensive care unit in order to determine level of acuity and mortality risk.
  • This information can then be used in a number of ways, such as to provide the family with a prognosis, for clinical trials, or for quality assessment.
  • The SOFA Score is not designed to influence medical management. As such, it should not be used dynamically or to determine success or failure of an intervention in the ICU.
