Clinical Notes

⚠️

Time-sensitive condition requiring immediate action

💡

qSOFA is for bedside screening without lab tests

SOFA requires laboratory values for organ assessment

📊

Higher scores correlate with increased mortality

Understanding Sepsis-3 Criteria

What is Sepsis?

Sepsis is a life-threatening condition characterized by a dysregulated host response to infection that leads to organ dysfunction. The Sepsis-3 criteria provide standardized definitions for identifying patients at risk of poor outcomes.

qSOFA vs SOFA

  • qSOFA: Quick screening tool for bedside use without laboratory tests
  • SOFA: Comprehensive organ dysfunction assessment requiring lab values
  • Both: Higher scores indicate increased risk and mortality

Clinical Workflow

Step 1: Suspect Infection
Clinical signs or laboratory evidence of infection
Step 2: qSOFA Screening
Rapid bedside assessment (≥2 points = high risk)
Step 3: SOFA Assessment
Detailed organ function evaluation (≥2 points = sepsis)
Step 4: Septic Shock Check
Vasopressor need + elevated lactate
