BODE index for COPD survival
4-year survival in COPD from BMI, obstruction, dyspnea, and exercise capacity.
Inputs
0 of 4FEV₁ (% predicted)
6-minute walk distance
mMRC dyspnea
BMI
When to use
- Stable COPD.
Pearls and pitfalls
- Better predictor of mortality than FEV1 alone; used in transplant referral.
Why use
Multidimensional COPD prognosis.
