Mortalidad en la UCI ~10%
Cómo usarla
- 1
Seis sistemas orgánicos. Respiratorio (cociente P/F), coagulación (plaquetas), neurológico (GCS), hepático (bilirrubina), cardiovascular (PAM/vasopresores), renal (creatinina/diuresis).
- 2
Delta SOFA. El cambio del SOFA en el tiempo predice el pronóstico mejor que un valor aislado.
- 3
Definición Sepsis-3. Sepsis = infección sospechada + aumento agudo del SOFA ≥2 respecto al basal.
Cuándo usarla
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.
- Ingreso y monitorización diaria en la UCI
- El SOFA seriado sigue la trayectoria de la disfunción orgánica.
- Diagnóstico de sepsis
- SOFA ≥2 respecto al basal = sepsis. Lactato ≥2 + SOFA ≥2 = shock séptico (de forma independiente).
- Asignación de recursos
- En pandemias, el SOFA ayuda a priorizar de forma coherente los recursos escasos de UCI.
Sobre la escala
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.
Preguntas frecuentes
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.
