BODE index and pulmonary rehabilitation in chronic respiratory failure

To the Editors: 

We read with interest the article by Cote and Celli 1 regarding the beneficial effects induced by pulmonary rehabilitation (PR) on the BODE (body mass index (BMI), degree of airway obstruction, dyspnoea, exercise capacity) index (BI) in patients with chronic obstructive pulmonary disease (COPD).

In an observational study, Cote and Celli 1 showed that the response to outpatient PR can be objectively measured using the BI, whose change provides information regarding ultimate survival, and that participation in a PR is associated with a decrease in the number of hospitalisations. This multidimensional 10-point scale has been previously shown to predict the death risk in COPD patients 2 …
