About
The Sequential Organ Failure Assessment (SOFA) score is used in the ICU to track the extent of organ dysfunction across six organ systems. It is calculated daily to assess the severity of organ failure and predict ICU mortality. A SOFA score ≥ 2 with suspected infection meets the Sepsis-3 definition of sepsis.
Formula
SOFA = Respiration + Coagulation + Liver + Cardiovascular + CNS + Renal
Each component scored 0–4, total range 0–24
Interpretation
| SOFA Score | Estimated Mortality |
|---|---|
| 0 – 6 | < 10% |
| 7 – 9 | 15–20% |
| 10 – 12 | 40–50% |
| ≥ 13 | > 80% |
