Sofa Score Icu Interpretation
The score is calculated on admission and every 24 hours until discharge using the worst parameters measured during the prior 24 hours.
Sofa score icu interpretation. The sequential organ failure assessment sofa score is a mortality prediction score that is based on the degree of dysfunction of six organ systems. The sequential organ failure assessment sofa score is a scoring system that assesses the performance of several organ systems in the body neurologic blood liver kidney and blood pressure hemodynamics and assigns a score based on the data obtained in each category. If mortality prediction could be achieved with the sofa score as accurately as with the apache iv model use of the sofa score would be preferable for that purpose. As individual scores for each organ to determine progression of organ dysfunction.
This means that the overall score is between 0 and 24. The scores can be used in a number of ways. The sofa score has been applied to initial critical care triage in some published triage protocols 4 7 even though the sofa score has only been validated as a severity of illness score for patients in the icu. The sofa score is much simpler compared to general icu prediction models such as the apache iv model which requires a lot of data and lays a heavy burden on precise data acquisition.
Unlike other scoring systems such as the saps ii and apache ii systems the sofa was designed to focus on organ dysfunction and morbidity with less of an emphasis on mortality prediction. The day 1 data in our study reflect the acute presentation of critically ill patients because. The sequential organ failure assessment sofa is a morbidity severity score and mortality estimation tool developed from a large sample of icu patients throughout the world. The sepsis 3 task force recommends that a positive qsofa score should prompt the calculation of a sofa score to confirm the diagnosis of sepsis.
The score is based on six different scores one each for the respiratory cardiovascular hepatic coagulation renal and neurological systems. The sequential organ failure assessment score sofa score previously known as the sepsis related organ failure assessment score is used to track a person s status during the stay in an intensive care unit icu to determine the extent of a person s organ function or rate of failure. This remains controversial as qsofa has been shown to be more predictive than sofa outside of the icu setting. Sofa score interpretation each of the answer choices in the 6 variables has assigned points from 0 normal function to 4 high degree of dysfunction.
The following table presents by comparison the score categories and the associated mortality percentages. Organ dysfunction is represented by an increase in the sequential sepsis related organ failure assessment sofa score 5 of 2 points or more which is associated with an in hospital mortality. The qsofa was derived by sepsis 3 to help identify patients with suspected infection who are at high risk for poor outcome defined as in hospital mortality or an icu stay of 3 days outside of the icu.
