Sepsis Risk Calculator
Assess sepsis risk using SIRS criteria and qSOFA. Sepsis is life-threatening organ dysfunction caused by dysregulated host response to infection. Early recognition reduces mortality from 40% to under 20% with prompt treatment.

Sepsis = Infection + SOFA ≥ 2 Septic shock = Vasopressors + Lactate > 2 Hour-1 Bundle critical
Ready to run the numbers?
Why: Early recognition and Hour-1 Bundle reduce mortality 50%+.
How: qSOFA screen → SOFA if positive. Infection + SOFA ≥ 2 = Sepsis.

Early treatment reduces mortality 50%+
— SCCM
Sepsis = Infection + SOFA ≥ 2
— Sepsis-3
Sepsis is life-threatening organ dysfunction caused by dysregulated host response to infection. Sepsis-3 (2016): Sepsis = suspected infection + SOFA ≥ 2. Septic shock = Sepsis + vasopressors + lactate > 2. Early recognition reduces mortality from 40% to under 20% with prompt Hour-1 Bundle treatment.

Key Takeaways
- • Sepsis = Infection + SOFA ≥ 2. Septic shock = Sepsis + vasopressors + lactate > 2
- • qSOFA for rapid screening; SOFA for diagnosis. Hour-1 Bundle: lactate, cultures, antibiotics, fluids
- • Early recognition and treatment reduce mortality from 40% to under 20%
- • High-risk sources: pneumonia, UTI, abdominal, skin, bloodstream

How Does Sepsis Assessment Work?
Step 1: qSOFA Screening
RR ≥22, SBP ≤100, altered mentation. Score ≥2 = high risk.
Step 2: SOFA Assessment
If qSOFA ≥2 or concern: calculate full SOFA. Infection + SOFA ≥ 2 = Sepsis.
Step 3: Septic Shock
Sepsis + vasopressors needed + lactate > 2 = Septic shock.
Expert Tips
Sepsis-3 Classifications
| Classification | Criteria | Mortality |
|---|---|---|
| No Sepsis | Infection without organ dysfunction | Less than 5% |
| Possible Sepsis | qSOFA positive, SOFA pending | 10-20% |
| Sepsis | Infection + SOFA ≥ 2 | 20-30% |
| Septic Shock | Sepsis + vasopressors + lactate > 2 | 40-50% |
Frequently Asked Questions
What is Sepsis?
Sepsis is life-threatening organ dysfunction caused by dysregulated host response to infection. Sepsis-3: suspected infection + SOFA ≥ 2. Early recognition reduces mortality from 40% to under 20% with prompt treatment.
How is sepsis diagnosed?
Sepsis-3: Suspected infection + SOFA score ≥ 2 (or acute increase ≥ 2). Septic shock = Sepsis + vasopressors to maintain MAP ≥ 65 + lactate > 2 mmol/L.
What is the Hour-1 Bundle?
Measure lactate, obtain blood cultures before antibiotics, administer broad-spectrum antibiotics, 30 mL/kg crystalloid if hypotension or lactate ≥ 4, vasopressors if fluid-refractory hypotension.
What is qSOFA vs SOFA?
qSOFA is 3 bedside criteria (RR, BP, mentation) for rapid screening outside ICU. SOFA is full 6-organ assessment; used for sepsis diagnosis and ICU monitoring.
What mortality does sepsis have?
Untreated sepsis: ~40% mortality. With early recognition and Hour-1 Bundle: under 20%. Septic shock: 40-50% mortality.
When to suspect sepsis?
Known/suspected infection + qSOFA ≥ 2, unexplained organ dysfunction, hemodynamic instability, altered mental status with fever. High-risk sources: pneumonia, UTI, abdominal, skin, bloodstream.
