qSOFA < 2 — riesgo bajo fuera de la UCI
Cómo usarla
- 1
3 criterios a pie de cama. FR ≥22, alteración del estado mental (cualquier GCS <15), PAS ≤100.
- 2
Umbral ≥2. Identifica, fuera de la UCI, a los pacientes con probable mala evolución por infección.
- 3
El qSOFA no es una definición de sepsis. Sepsis-3: infección sospechada + SOFA ≥2. El qSOFA es un aviso de cribado, no un criterio diagnóstico.
Cuándo usarla
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.
- Cribado rápido en planta y urgencias
- qSOFA ≥2 en un paciente con sospecha de infección: SOFA, lactato y hemocultivos urgentes.
- No para la UCI
- El SOFA es la herramienta validada en la UCI.
- Ambulatorio/comunidad
- El qSOFA mostró un buen rendimiento fuera de la UCI en las cohortes de validación de Sepsis-3.
Sobre la escala
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.
Preguntas frecuentes
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.
