Sepsis-3

• After nearly 2 decades, the definitions for sepsis and septic shock have been updated.
• Key findings from the Task Force convened by SCCM and ESICM include:
  • Sepsis
    • Definition: life-threatening organ dysfunction due to a dysregulated host response to infection
    • ICU patients: organ dysfunction is defined as an increase of 2 points or more in the Sequential Organ Failure Assessment (SOFA) score
    • ED patients: 2 or more of the following new qSOFA (quickSOFA) score may identify patients with increased mortality
      • SBP less than or equal to 100 mm Hg
      • RR greater than or equal to 22
      • Altered mental status
  • Septic Shock
    • Definition: a subset of patients with sepsis and profound circulatory, cellular, and metabolic abnormalities
    • Clinical Criteria:
      • Persistent hypotension requiring vasopressors to maintain MAP greater than or equal to 65 mm Hg despite adequate volume resuscitation
      • Lactate greater than or equal to 2 mmol/L
  • The term "severe sepsis" is no longer used
