What qSOFA score suggests high sepsis risk?

qSOFA ≥2 identifies patients outside ICU at high risk for sepsis; each criterion (RR≥22, altered mentation, SBP≤100) = 1 point; qSOFA ≥2 has sensitivity 70%, specificity 79% for sepsis identification.

What were the original SIRS criteria replaced by qSOFA?

SIRS criteria (temp >38 or 90, RR >20, WBC >12K or <4K) are now considered too non-specific; SIRS is positive in 95% of ICU admissions regardless of infection; qSOFA is more specific for organ dysfunction.

Can qSOFA replace full SOFA outside the ICU?

qSOFA was intended as a bedside prompt, not diagnostic; positive qSOFA should trigger measurement of lactate and organ function (full SOFA calculation); blood cultures and antibiotics should not wait for full SOFA calculation.

What time target is critical for sepsis treatment?

Hour-1 bundle (SSC 2018): measure lactate, blood cultures before antibiotics, broad-spectrum antibiotics within 1 hour for septic shock; 30 mL/kg IV crystalloid within 3 hours for hypotension/lactate ≥4 mmol/L.

What is septic shock definition per Sepsis-3?

Septic shock = sepsis + vasopressor required to maintain MAP ≥65 mmHg + lactate >2 mmol/L despite adequate fluid resuscitation; hospital mortality approximately 40%; vasopressor and ICU admission are required.

qSOFA (Quick SOFA) Sepsis Screening Tool

Applies the quick SOFA (qSOFA) criteria to identify patients outside the ICU with suspected infection at high risk of sepsis complications: respiratory rate ≥22, altered mentation, and systolic BP ≤100 mmHg.
