Replacement of the 6-Min Walk Test With Glittre ADL Test and Scores From the PFSDQ-M and HAP Questionnaires in the BODE Index.

Purpose: Chronic obstructive pulmonary disease reduces functional capacity, which is strongly correlated with the morbidity and mortality of patients. The BODE index considers the multifactorial nature of the disease, including the functional capacity measured by the 6-min walk test (6MWT), and this index predicts the mortality in patients with chronic obstructive pulmonary disease. Our aim was to assess whether association exists between the original BODE index and the modified BODE index by replacing the 6MWT with the scores from the Pulmonary Functional Status and Dyspnea Questionnaire-Modified version (PFSDQ-M), Human Activity Profile (HAP) questionnaire, and the results of the Glittre ADL Test (TGlittre).
