CURB-65 Score (Pneumonia Severity)

Calculate the CURB-65 score to assess community-acquired pneumonia (CAP) severity and guide the site of care. Each component scores 1 point: Confusion (new-onset disorientation), Urea > 7 mmol/L (BUN > 20 mg/dL), Respiratory rate ≥ 30/min, Blood pressure (systolic < 90 OR diastolic ≤ 60 mmHg), and Age ≥ 65. Range 0–5. Interpretation: 0–1 low risk (likely outpatient; 30-day mortality ~1.5–2.4%), 2 moderate (consider admission or supervised discharge, ~9.2%), 3–5 high risk (hospital admission; consider ICU for 4–5; mortality rises to ~57% at score 5). Endorsed by the British Thoracic Society. Derived from Lim et al. 2003 (Thorax). Not medical advice.
