qSOFA Score Calculator
Enter three bedside findings — mental status, respiratory rate, and systolic blood pressure — to calculate the qSOFA score and assess sepsis risk.
For educational use only. Not a substitute for clinical judgment. All sepsis assessments must be made by qualified clinicians alongside full patient evaluation.
Bedside Criteria
Three parameters — all obtainable without lab tests.
Glasgow Coma Scale below 15 — any new confusion, disorientation, or reduced responsiveness.
Score 1 point if 22 or more per minute. Normal adult range: 12–20/min.
Score 1 point if 100 mmHg or below. Normal: 100–140 mmHg.
Enter the three bedside values
and click Calculate.

Score Interpretation
Summary
Enter three bedside findings — mental status, respiratory rate, and systolic blood pressure — to calculate the qSOFA score and assess sepsis risk.
How it works
- Select whether the patient has altered mental status (GCS below 15).
- Enter the respiratory rate in breaths per minute.
- Enter the systolic blood pressure in mmHg.
- Click Calculate to receive the total qSOFA score (0–3).
- A score of 2 or 3 indicates high sepsis risk and warrants urgent clinical evaluation.
- Use results alongside full clinical assessment; a low qSOFA does not rule out sepsis.
Use cases
- Rapidly screen ward or emergency department patients with suspected infection for sepsis risk.
- Triage patients who may need ICU-level monitoring or early sepsis bundle initiation.
- Guide the decision to obtain blood cultures, lactate, and full SOFA evaluation.
- Communicate sepsis risk to the clinical team using a standardized, reproducible score.
- Support early intervention to reduce mortality in high-risk patients.
- Use as a teaching aid in medical education for sepsis recognition.
- Track serial qSOFA assessments in patients with evolving clinical status.
- Apply in resource-limited settings where lab values for full SOFA may be unavailable.
