qSOFA < 2 — niedriges Risiko außerhalb der Intensivstation
So wendest du ihn an
- 1
3 Kriterien am Krankenbett. Atemfrequenz ≥22, Bewusstseinsänderung (jede GCS <15), systolisch ≤100.
- 2
Schwelle ≥2. Identifiziert Patienten außerhalb der Intensivstation mit wahrscheinlich ungünstigem Verlauf durch eine Infektion.
- 3
qSOFA ist keine Sepsis-Definition. Sepsis-3: Infektionsverdacht + SOFA ≥2. qSOFA ist ein Screening-Signal, keine Diagnose.
Wann du ihn einsetzt
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.
- Schnelles Screening auf Station und in der Notaufnahme
- qSOFA ≥2 bei Infektionsverdacht: dringlich SOFA, Laktat, Blutkulturen.
- Nicht auf der Intensivstation
- Auf der Intensivstation ist der SOFA-Score das validierte Instrument.
- Ambulant/präklinisch
- qSOFA zeigte in den Validierungskohorten von Sepsis-3 außerhalb der Intensivstation eine gute Leistung.
Über den 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.
Häufige Fragen
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.
