qSOFA Score Calculator
Calculate the quick SOFA (qSOFA) score for rapid sepsis screening at the bedside. Three criteria: altered mental status (GCS <15), respiratory rate ≥22, systolic BP ≤100. Score ≥2 suggests high risk of poor outcome.
Why This Health Metric Matters
Why: qSOFA rapidly identifies high-risk patients for urgent intervention.
How: Enter respiratory rate, systolic BP, and mental status. Score 2+ indicates high risk.
- ●3 criteria: RR≥22, SBP≤100, altered mentation
- ●Score 2+ = high risk
- ●Part of Sepsis-3

🏥 Health Facts
3-item bedside tool, no labs needed
— Sepsis-3
Score 2+ associated with >10% mortality
— Clinical
The quick SOFA (qSOFA) is a 3-item bedside tool for rapid sepsis screening outside the ICU. Criteria: respiratory rate ≥22/min, systolic BP ≤100 mmHg, altered mental status (GCS <15). Score ≥2 suggests high risk for poor outcome. Part of Sepsis-3 (2016). No labs needed—can be done at bedside in seconds.

Key Takeaways
- • qSOFA = 3 bedside criteria: RR ≥22, SBP ≤100, altered mentation. No labs needed.
- • Score ≥2 = high risk for poor outcome; initiate sepsis bundle if infection suspected.
- • Use outside ICU for rapid screening. ICU patients: use full SOFA.
- • Less sensitive than SIRS; negative qSOFA does not rule out sepsis.
Did You Know?
How Does qSOFA Work?
Three Criteria
Respiratory rate ≥22/min (1 pt), Systolic BP ≤100 mmHg (1 pt), Altered mental status/GCS <15 (1 pt). Sum = 0-3.
Interpretation
Score 0: low risk. Score 1: intermediate, monitor closely. Score 2-3: high risk, sepsis likely if infection present.
Next Steps
qSOFA ≥2 + suspected infection: obtain lactate, cultures; start antibiotics; fluid resuscitation; consider ICU.

| 1 | Intermediate | 2-3% |
| 2-3 | High Risk | >10% |
Frequently Asked Questions
What is the qSOFA score?
qSOFA is a 3-item bedside tool (respiratory rate, blood pressure, mental status) for rapid sepsis screening outside the ICU. Part of Sepsis-3 definitions.
What qSOFA score indicates sepsis risk?
Score 2 or 3 indicates high risk for poor outcome if infection is present. Score 0-1 suggests lower risk.
How is qSOFA calculated?
1 point each for: respiratory rate ≥22/min, systolic BP ≤100 mmHg, altered mental status (GCS <15). Total 0-3.
When should qSOFA be used?
For patients with suspected infection in ED, wards, or pre-hospital settings. Not for ICU patients (use full SOFA).
What are qSOFA limitations?
Less sensitive than SIRS. Negative qSOFA does not rule out sepsis. Does not replace clinical judgment.
What is the mortality risk by qSOFA score?
Score 0: <1% mortality. Score 1: 2-3%. Score 2-3: >10% mortality.
