Mortalité en réanimation ~10%
Comment l’utiliser
- 1
Six systèmes d’organes. Respiratoire (rapport P/F), coagulation (plaquettes), neurologique (GCS), hépatique (bilirubine), cardiovasculaire (PAM/vasopresseurs), rénal (créatinine/diurèse).
- 2
Delta SOFA. L’évolution du SOFA dans le temps prédit mieux le pronostic qu’une valeur isolée.
- 3
Définition Sepsis-3. Sepsis = infection suspectée + augmentation aiguë du SOFA ≥2 par rapport à l’état de base.
Quand l’utiliser
Use in all ICU patients for daily monitoring of organ dysfunction, prognosis estimation, and to operationalise the Sepsis-3 definition of sepsis in patients with suspected infection.
- Admission et surveillance quotidienne en réanimation
- Le SOFA répété suit la trajectoire des dysfonctions d’organes.
- Diagnostic du sepsis
- SOFA ≥2 par rapport à l’état de base = sepsis. Lactates ≥2 + SOFA ≥2 = choc septique (indépendamment).
- Allocation des ressources
- En pandémie, le SOFA aide à trier de façon cohérente les ressources rares de réanimation.
À propos du score
The Sequential Organ Failure Assessment (SOFA) score is the gold-standard tool for quantifying organ dysfunction in critically ill patients. It evaluates six organ systems — respiratory, coagulation, hepatic, cardiovascular, neurological, and renal — each scored 0 to 4, giving a total of 0 to 24. According to the Sepsis-3 consensus definitions (2016), sepsis is defined as a life-threatening organ dysfunction caused by infection, operationally identified by an acute increase in SOFA score of ≥2 points from baseline in a patient with suspected infection. SOFA is also used as a prognostic tool, with higher scores correlating with increased ICU mortality.
Questions fréquentes
What SOFA score defines sepsis?
Per the Sepsis-3 consensus (2016), sepsis is defined as an acute increase in SOFA score of ≥2 points from baseline in a patient with suspected or confirmed infection. The SOFA score operationalises the concept of life-threatening organ dysfunction in this context.
What is the difference between SOFA and qSOFA?
SOFA is the full six-organ scoring system requiring lab values and ICU parameters. qSOFA (quick SOFA) is a rapid bedside screen using three criteria: respiratory rate ≥22/min, altered mentation (GCS <15), and systolic BP ≤100 mmHg. qSOFA identifies patients outside the ICU who may be deteriorating; a positive qSOFA (≥2) warrants full SOFA assessment.
