Lower Respiratory Tract Infection (LRTI) Severity Score
CURB-65 severity score for adults with community-acquired pneumonia (Lim 2003). In the community, without a urea result, NICE CG191 uses CRB-65.
Used in: Pneumonia
Score interpretation
CURB-65 low risk (0-1)
CURB-65 0–1: 1.5% 30-day mortality
→ Low severity; consider home treatment with oral antibiotics
CURB-65 moderate risk (2)
CURB-65 2: 9.2% 30-day mortality
→ Moderate severity; consider hospital admission or close outpatient follow-up
CURB-65 high risk (3-5)
CURB-65 3–5: 22% 30-day mortality
→ High severity pneumonia; hospital admission; ICU assessment if score 4-5
Interpretation bands for the LRTI Severity. Apply clinical judgement and local guidance.
