Sequential Organ Failure Assessment (SOFA) Score Calculator
Disclaimer: Diagnosis is usually made clinically. If the score from the calculator indicates that you might be at risk please consider visiting a doctor for further evaluation.
A useful tool for evaluating and tracking the level of organ dysfunction and failure in critically ill patients is the Sequential Organ Failure Assessment (SOFA) score. It was initially created for sepsis patients, but it has subsequently gained widespread acceptance as a tool for evaluating the general health and prognosis of those who are severely unwell. We shall examine the SOFA score’s salient features, its constituent parts, and its clinical relevance in this article.
During a consensus conference introduced by the European Society of Intensive Care and Emergency Medicine in 1994, the SOFA (Sequential Organ Failure Assessment) scoring system was created to evaluate the progression of organ failure in both sepsis patients as a whole and in subgroups of patients. The score was originally known as the “Sepsis-Related Organ Failure Assessment Score,” but it was later changed to the Sequential Organ Failure Assessment when it was realized that it could be used equally for patients who were not septic.
Six organ systems are evaluated by the SOFA score, with scores ranging from 0 to 4, with higher values indicating more severe dysfunction:
- Respiratory system
- Cardiovascular system
- Central nervous system
- Liver
- Coagulation system
- Renal system
The SOFA score ranges from 0 to 24 and is calculated by adding the values for each of the six different factors. Higher SOFA scores are associated with increased organ dysfunction and mortality risk.
