Dyspnoea, Eosinopenia, Consolidation, Acidaemia, and Atrial Fibrillation (DECAF) score predicts in-hospital mortality in acute exacerbations of COPD.

Used in: COPD

Score interpretation

Low Risk 0–1

DECAF 0–1 — in-hospital mortality ~1–2%

→ Standard ward-based AECOPD management; consider early supported discharge

Moderate Risk 2–3

DECAF 2–3 — in-hospital mortality ~7–15%

→ Standard inpatient management; close monitoring; low threshold for HDU if deteriorating

High Risk 4–6

DECAF ≥4 — in-hospital mortality >25–50%

→ HDU/ICU admission; early NIV if pH <7.35; goals-of-care discussion; consider palliative input
