The European Society of Intensive Care Medicine and the Society of Critical Care Medicine recently teamed up in a critical care task force to redefine sepsis as numerous medical advances have been made since the 2001 revisions.
The major take home points from the new definition include the following:
- Sepsis: Life-threatening organ dysfunction caused by a dysregulated host response to infection
- Septic shock: Sepsis with circulatory and cellular/metabolic abnormalities profound enough to substantially increase mortality
- Clinical Criteria:
- Sepsis: Suspected or documented infection and an acute increase of ≥ 2 SOFA points
- Septic Shock: Sepsis and vasopressor therapy needed to elevate MAP ≥ 65 mmg Hg and lactate > 2 mmol/L (18 mg/dL) after adequate fluid resuscitation
What is SOFA??? It sands for Sepsis-related Organ Failure Assessment and it serves as a proxy for organ dysfunction. The qSOFA score (aka quickSOFA) is a bedside tool that may identify patients at higher risk of poor outcomes outside of the ICU. The 3 parameters assessed by the tool include respiratory rate (high defined as ≥22 breaths/min), low blood pressure defined as SBP≤100 mmHg, and altered mental status defined as a GSC <15 and the tool assigns one point for each measure. The tool may help identify patients that should trigger a lower threshold to be moved to the ICU setting.
