Organ dysfunction is a condition where an organ does not perform its expected function. Organ failure is organ dysfunction to such a degree that normal homeostasis cannot be maintained without external clinical intervention.
However, there are tools physicians use when diagnosing multiple organ failure and when prognosing the outcome. The Sequential Organ Failure Assessment (SOFA) score uses early lab values in a patient's hospitalization (within 24 hours) to predict fatal outcomes for a patient.
