SOFA Score ICU Calculator
Track Sequential Organ Failure Assessment to evaluate organ dysfunction severity in the ICU
ICU Organ Dysfunction
An increase in SOFA score of ≥2 points from baseline indicates acute organ dysfunction, representing a positive screen for sepsis under Sepsis-3 criteria (Singer et al., JAMA 2016).

What is the SOFA score?
The Sequential Organ Failure Assessment (SOFA) score is a scoring system used in ICU settings to track a patient's organ dysfunction level across six organ systems: respiratory, cardiovascular, hepatic, coagulation, renal, and neurological.
How does the SOFA score define organ dysfunction severity?
Each of the six organ systems is scored from 0 (normal) to 4 (severe dysfunction), yielding a total score between 0 and 24. A higher score is associated with higher mortality risk.
What is the clinical significance of a change in SOFA score?
An increase in SOFA score of ≥2 points from baseline indicates acute organ dysfunction, representing a positive screen for sepsis under Sepsis-3 criteria and indicating a 10% or greater hospital mortality risk.
Can SOFA score be used to diagnose sepsis?
Yes. Sepsis is defined as a suspected or documented infection accompanied by an acute increase of ≥2 points in the SOFA score, indicating organ dysfunction due to the infection.
