Formula and scoring

B: BMI >21 0, ≤21 1. O: FEV₁ ≥65 0, 50–64 1, 36–49 2, ≤35 3. D: mMRC 0–1 0, 2 1, 3 2, 4 3. E: 6MWD ≥350 0, 250–349 1, 150–249 2, ≤149 3.

Exam and ward pearls

  • C statistic 0.74 for BODE vs 0.65 for FEV₁ alone.

When not to rely on it

  • Validated in stable COPD, not during exacerbations.
