qSOFA Sepsis Screening Score

Screen for sepsis risk outside the ICU using qSOFA: altered mentation (GCS <15), respiratory rate ≥22, and systolic BP ≤100. Score ≥2 predicts poor outcomes.

Clinical Guidance

BMI is a screening measure of body size, not a direct measure of body fat. The standard WHO categories are underweight (<18.5), normal (18.5–24.9), overweight (25–29.9), and obese (≥30).

BMI can overestimate body fat in athletes with high muscle mass and underestimate it in older adults with low muscle mass. Interpret it alongside waist circumference and clinical context rather than as a standalone diagnosis.

How It Works

Screen for sepsis risk outside the ICU using qSOFA: altered mentation (GCS <15), respiratory rate ≥22, and systolic BP ≤100. Score ≥2 predicts poor outcomes

Each component has a specific meaning:

  • QSOFA: altered mentation — The qsofa: altered mentation recorded for the scenario being assessed.
  • Respiratory rate ≥22 — The respiratory rate ≥22 recorded for the scenario being assessed.
  • Systolic BP ≤100 — The systolic bp ≤100 recorded for the scenario being assessed.

Note: Interpret the qsofa result against the thresholds and context described above.

How to Use

Enter the qSOFA: altered mentation, respiratory rate ≥22, systolic BP ≤100 for the scenario you are assessing. Screen for sepsis risk outside the ICU using qSOFA: altered mentation (GCS <15), respiratory rate ≥22, and systolic BP ≤100. Score ≥2 predicts poor outcomes. Use the qsofa result to inform your calculation.
