Development of a modified BODE index as a mortality risk measure among older adults with and without chronic obstructive pulmonary disease.

ABSTRACT: The BODE index was developed as a prognostic mortality risk tool for persons with chronic obstructive pulmonary disease (COPD). It incorporates 4 measures: body mass index, lung obstruction, dyspnea, and exercise capacity. The intent of this study was to examine how well a BODE-like index constructed using a simpler lung function measure, peak expiratory flow, in combination with physical functioning and symptom information more readily found in survey data (a quasi-BODE index), performs in identifying persons at higher risk of mortality and whether it may be extended as an assessment of mortality risk to persons without diagnosed COPD.
