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. It consists of three criteria: respiratory rate, systolic blood pressure, and mental status.

2. How Does the Calculator Work?

The calculator uses the QSOFA equation:

Where:

• Respiratory — Respiratory rate ≥22/min (1 point if yes)
• Systolic — Systolic blood pressure ≤100 mmHg (1 point if yes)
• Mental — Altered mental status (1 point if yes)

Explanation: The score ranges from 0-3 points, with higher scores indicating greater risk of poor outcomes in patients with suspected infection.

3. Importance of QSOFA Score

Details: QSOFA helps quickly identify patients with suspected infection who may need more intensive monitoring or care. A score of ≥2 points is associated with higher risk of mortality and prolonged ICU stay.

4. Using the Calculator

Tips: Select "Yes" for each criterion that applies to the patient. The calculator will automatically sum the points to provide the QSOFA score.

5. Frequently Asked Questions (FAQ)

Q1: What is considered an altered mental status?
A: Any acute change in mental status, including confusion, disorientation, drowsiness, or Glasgow Coma Scale score <15.

Q2: How does QSOFA differ from SOFA?
A: QSOFA is a simplified version designed for quick bedside assessment, while SOFA is more comprehensive and includes laboratory values.

Q3: When should QSOFA be used?
A: QSOFA should be used for initial rapid assessment of patients with suspected infection outside the ICU.

Q4: What does a QSOFA score of 2 or more indicate?
A: A score ≥2 suggests higher risk of poor outcomes and may indicate need for more intensive monitoring or treatment.

Q5: Can QSOFA be used for pediatric patients?
A: No, QSOFA was developed and validated for use in adult patients only.
