Résultat
0/3
qSOFA < 2 — risque faible hors réanimation
Comment l’utiliser
- 1
3 critères au lit du patient. FR ≥22, altération de la conscience (tout GCS <15), PAS ≤100.
- 2
Seuil ≥2. Identifie, hors réanimation, les patients susceptibles d’évoluer défavorablement du fait d’une infection.
- 3
Le qSOFA n’est pas une définition du sepsis. Sepsis-3 : infection suspectée + SOFA ≥2. Le qSOFA est une alerte de dépistage, pas un outil diagnostique.
Quand l’utiliser
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.
- Dépistage rapide en service et aux urgences
- qSOFA ≥2 chez un patient suspect d’infection : SOFA, lactates et hémocultures en urgence.
- Pas en réanimation
- Le SOFA est l’outil validé en réanimation.
- Ambulatoire/ville
- Le qSOFA s’est montré performant hors réanimation dans les cohortes de validation de Sepsis-3.
À propos du 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.
Questions fréquentes
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.
