Calculate qSOFA Score

Assess sepsis risk using 3 simple clinical criteria.

Glasgow Coma Scale (GCS) score < 15.

Is the breathing rate ≥ 22 breaths per minute?

Is the systolic blood pressure ≤ 100 mmHg?

Understanding the Math

What Is the qSOFA Sepsis Score?

The qSOFA (Quick Sequential Organ Failure Assessment) score is a simplified, bedside clinical tool designed to quickly identify adult patients with suspected infection who are at high risk for poor outcomes outside the Intensive Care Unit (ICU).

Unlike more complex scoring systems, it only requires three straightforward clinical criteria, allowing for immediate risk stratification without the need for waiting on laboratory blood tests.

How to Interpret the Results

qSOFA Score Risk Level Clinical Implication Recommended Action
0 to 1 Low Risk Not identified as high risk for in-hospital mortality. Continue standard monitoring and care.
2 to 3 High Risk 3- to 14-fold increase in hospital mortality rate. Assess for organ dysfunction, escalate therapy, and consider ICU transfer.
Understanding The Criteria
🧠

Altered Mental Status

A Glasgow Coma Scale (GCS) score of less than 15 indicates an altered state of consciousness. This is a critical early warning sign of reduced oxygen flow or systemic distress to the brain.

🫁

Respiratory Rate

A breathing rate of 22 breaths per minute or higher (tachypnea) suggests the body is compensating for a severe underlying infection or struggling to oxygenate tissues effectively.

🫀

Systolic Blood Pressure

A systolic blood pressure reading of 100 mmHg or lower indicates hypotension, signaling potential circulatory compromise or shock, a life-threatening complication of sepsis.

🩺

Clinical Application

qSOFA is not a definitive diagnostic test for sepsis, but rather a "prompt" to flag patients who require closer monitoring and potentially aggressive medical intervention.

Actionable Guidelines
Clinical Next Steps

What to Do If the Score is High

  • 1
    Seek Immediate Evaluation — If a patient scores a 2 or a 3, they require urgent evaluation by a critical care physician or emergency medical team.
  • 2
    Assess for Organ Dysfunction — Utilize comprehensive scoring systems, like the full SOFA score, which includes laboratory values (bilirubin, creatinine, platelets, etc.) to evaluate specific organ failures.
  • 3
    Monitor Lactate Levels — Checking serum lactate levels can provide further insight into tissue perfusion and the severity of the systemic response.
  • 4
    Escalate Care Resources — Prepare for potential transfer to an intensive care unit (ICU) and begin appropriate protocol-based sepsis interventions (e.g., fluid resuscitation, early antibiotics).
FAQs

Common Questions About the qSOFA Score

What is the difference between qSOFA and the full SOFA score? +
The full SOFA (Sequential Organ Failure Assessment) score requires laboratory blood tests (such as PaO2, platelet count, bilirubin, and creatinine) and takes longer to calculate. The qSOFA is a "quick" bedside version designed to be used rapidly without waiting for lab results.
Does a high qSOFA score mean the patient definitely has sepsis? +
No. qSOFA is not a definitive diagnostic tool for sepsis. Rather, it is a predictor of poor outcomes (like prolonged ICU stay or mortality) in patients who already have a suspected infection. A high score means the patient is high-risk and needs immediate evaluation.
Why was the SIRS criteria replaced or supplemented by qSOFA? +
In 2016, the Third International Consensus Definitions for Sepsis and Septic Shock (Sepsis-3) introduced qSOFA. It was found that the older SIRS (Systemic Inflammatory Response Syndrome) criteria were often too broad and unhelpful for identifying patients at the highest risk for death outside of the ICU.
Can I calculate this at home? +
While the inputs (breathing rate, blood pressure, and mental state) are simple, this tool is intended for use by trained healthcare professionals in clinical settings. If you suspect a severe infection or sepsis at home, seek emergency medical care immediately rather than relying on an online calculator.
