a multidimensional approach-the BODE index-has been proposed for prognostic purposes in chronic obstructive pulmonary disease (COPD) and theoretically seems to be well suited for elderly people, but there is a lack of data in this population, especially with respect to long-term survival. The objective of this study is to evaluate whether the BODE index can predict both long (5 years) and very-long (10 and 15 years)-term mortality in an unselected population of elderly people with COPD better than a set of variables commonly taken into account in a geriatric multidimensional assessment (MDA).


: this was a multicentre, prospective, population study. We used data from the SaRA study, which included 563 elderly people with COPD whose vital status was ascertained for up to 15 years after enrolment. The discriminative capacity of the BODE index in predicting mortality was derived from Cox proportional hazard models including the components of the BODE index and compared with that of an alternative model based on MDA variables: age, gender, physical disability, cognitive function and mood status.


: at 5 years, the HRs for mortality were 1.04 (95% CI: 0.60-1.79), 1.88 (1.10-3.22) and 3.55 (2.15-5.86) for quartiles 2-4, respectively, compared with quartile 1 of the BODE index. The corresponding figures for 10-year mortality were 1.50 (1.01-2.24), 2.11 (1.39-3.20) and 3.903 (2.62-5.82), and for 15-year mortality were 1.68 (1.19-2.36), 2.08 (1.44-3.01) and 3.78 (2.64-5.41). Similar results were obtained using variables included in the usual MDA.


: Both the 'classic' MDA and the BODE index are comparably associated with mortality, even at very long term, in elderly people with COPD.
