1. What is the qSOFA Score?

The qSOFA (quick Sequential Organ Failure Assessment) score is a bedside tool to identify adult patients with suspected infection who are at greater risk for poor outcomes. A score of 2 or more points indicates high risk.

2. How Does the Calculator Work?

The calculator evaluates three criteria:

  • Respiratory rate ≥22/min (1 point)
  • Altered mentation (1 point)
  • Systolic blood pressure ≤100 mmHg (1 point)

Interpretation:

3. Importance of qSOFA Score

Details: The qSOFA score helps quickly identify patients with suspected infection who may need more intensive monitoring or treatment. It's simpler than full SOFA score but still predictive of poor outcomes.

4. Using the Calculator

Tips: Enter the patient's respiratory rate, systolic blood pressure, and mental status. The calculator will determine the qSOFA score and risk assessment.

5. Frequently Asked Questions (FAQ)

Q1: When should qSOFA be used?
A: For adult patients with suspected infection outside the ICU, to identify those at risk of sepsis.

Q2: What does qSOFA ≥2 indicate?
A: High risk of poor outcome (mortality or prolonged ICU stay). These patients need close monitoring.

Q3: How does qSOFA differ from SIRS criteria?
A: qSOFA is more specific but less sensitive than SIRS for identifying sepsis risk.

Q4: Can qSOFA be used in children?
A: No, qSOFA is validated only for adult patients.

Q5: What actions should follow a high qSOFA score?
A: Consider ICU consultation, initiate sepsis protocol, and monitor closely for organ dysfunction.
