BODE Index for COPD Survival
Multidimensional prognosis in COPD from BMI, obstruction, dyspnoea and exercise.

- Approx. 4-year survival
- ~80 %
When to use
- Estimating mortality risk and staging severity in stable COPD beyond FEV1 alone.
Formula
Sum of points for FEV1 % predicted (0–3), 6-minute walk distance (0–3), mMRC dyspnoea (0–3) and BMI ≤ 21 (0–1). Range 0–10; higher predicts worse survival.
Pearls and pitfalls
- Validated in stable disease, not during exacerbations.
- The exercise and dyspnoea components carry prognostic weight independent of spirometry.
