Understanding the SOFA Score in Sepsis 3 The cornerstone of the sepsis 3 criteria is the SOFA score, which quantifies organ function across six systems: respiratory, cardiovascular, hepatic, coagulation, renal, and neurological. The sepsis 3 criteria , published in 2016, established a new definition and clinical framework designed to improve recognition and outcomes.
Understanding the SOFA Score Increase in Sepsis 3
An increase in the total SOFA score of 2 points or more following a suspected infection indicates significant organ dysfunction and confirms the diagnosis of sepsis under this definition. The respiratory component assesses the partial pressure of oxygen (PaO2) to fraction of inspired oxygen (FiO2) ratio, reflecting oxygenation efficiency.
Differentiating Sepsis, Severe Sepsis, and Septic Shock The sepsis 3 criteria simplified the historical subclassifications of severe sepsis and septic shock into a more linear progression. Sepsis is defined by the SOFA score increase, while septic shock is identified by sepsis with persisting hypotension requiring vasopressors to maintain a mean arterial pressure of 65 mm Hg or greater and with serum lactate level greater than 2 mmol/L despite adequate volume resuscitation.
Sepsis 3 Criteria SOFA Score Increase of 2 Points
This objective assessment provides a clear threshold for clinicians to distinguish sepsis from less severe infections. Cardiovascular evaluation focuses on the mean arterial pressure and the need for vasopressor support to maintain adequate perfusion.
