qSOFA Score

qSOFA (Quick SOFA) Score

Criteria	No (0)	Yes (+1)
Altered mental status (GCS <15)	0	1
Respiratory rate ≥22 breaths/min	0	1
Systolic BP ≤100 mmHg	0	1
qSOFA Score	0   / 3

Interpretation
0–1	Low Risk — Not high risk for in-hospital mortality. Continue standard evaluation.
≥2	High Risk — Associated with ≥10% in-hospital mortality. Consider ICU-level care, lactate, blood cultures, and broad-spectrum antibiotics.

SIRS Criteria

SIRS Criteria

Criteria	No (0)	Yes (+1)
Temperature >38°C (100.4°F) or <36°C (96.8°F)	1
Heart rate >90 bpm	1
Respiratory rate >20 breaths/min or PaCO₂ <32 mmHg	1
WBC >12,000/mm³ or <4,000/mm³ or >10% bands	1
SIRS Criteria Met	/ 4

Interpretation
0–1	SIRS criteria NOT met — Fewer than 2 criteria present.
≥2	SIRS criteria MET — If infection is suspected or confirmed, meets criteria for sepsis (per Sepsis-1/2 definition). Note: Sepsis-3 uses qSOFA/SOFA criteria instead.
