| Description | Sequential Organ Failure Assessment (SOFA) score for assessing organ dysfunction in critically ill patients. Evaluates six organ systems (respiratory, cardiovascular, hepatic, coagulation, renal, neurological), each scored 0-4 points. Total score ranges from 0 to 24, with higher scores indicating more severe organ dysfunction. |
