Quick Sequential Organ Failure Assessment
Snelle beoordeling van orgaanfalen bij sepsis.
Inhoud in het Engels
qSOFA-calculator
Uitkomst
0/3
qSOFA < 2 — laag risico buiten de IC
Hoe je hem gebruikt
- 1
3 criteria aan het bed. Ademfrequentie ≥22, veranderd bewustzijn (elke GCS <15), systolisch ≤100.
- 2
Drempel ≥2. Identificeert patiënten buiten de IC met waarschijnlijk een slechte uitkomst door een infectie.
- 3
qSOFA is geen definitie van sepsis. Sepsis-3: verdenking op infectie + SOFA ≥2. qSOFA is een screeningssignaal, geen diagnose.
Wanneer je hem gebruikt
Use as a bedside screening tool in any patient with suspected infection outside the ICU, particularly in emergency departments and general wards. Positive qSOFA should trigger full SOFA assessment, blood cultures, lactate measurement, and urgent clinical review.
- Snelle screening op de afdeling en de SEH
- qSOFA ≥2 bij verdenking op infectie: met spoed SOFA, lactaat en bloedkweken.
- Niet op de IC
- Op de IC is de SOFA het gevalideerde instrument.
- Poliklinisch/eerstelijn
- qSOFA presteerde goed buiten de IC in de validatiecohorten van Sepsis-3.
Over de score
The quick SOFA (qSOFA) score is a rapid, three-criterion bedside tool introduced with the Sepsis-3 consensus definitions in 2016. It was designed to identify patients outside the ICU — in emergency departments, general wards, or primary care settings — who may have sepsis and are at risk of poor outcomes. Unlike the full SOFA score, qSOFA requires no laboratory tests, making it immediately applicable in any clinical setting. A positive qSOFA (≥2 of 3 criteria) should prompt clinical reassessment, consideration of sepsis, and escalation of care — including measurement of lactate and blood cultures.
Veelgestelde vragen
What is a positive qSOFA score?
A qSOFA score of ≥2 out of 3 is considered positive and indicates that sepsis should be suspected. This should prompt immediate escalation: blood cultures, lactate measurement, IV access, and consideration of broad-spectrum antibiotics within the 1-hour sepsis bundle.
What is the difference between qSOFA and SIRS criteria?
SIRS (Systemic Inflammatory Response Syndrome) criteria were used in Sepsis-1 and Sepsis-2 definitions and included temperature, heart rate, respiratory rate, and white blood cell count. They were replaced by SOFA/qSOFA in Sepsis-3 (2016) because SIRS lacked specificity and could be met by non-infectious conditions. qSOFA focuses on clinical signs of organ dysfunction rather than the inflammatory response.
