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

Abstract

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).

Methods: 

Twenty-eight subjects diagnosed with chronic obstructive pulmonary disease underwent the 6MWT and TGlittre and responded to the PFSDQ-M and HAP questionnaires. Four BODE index scores were obtained: 1 calculated by using the original method (ie, using the 6MWT) and 3 others calculated by using the results obtained from the TGlittre, PFSDQ-M, and HAP (the modified BODE index scores).

Results: 

High levels of association were observed between the original BODE index and the BODE TGlittre (R² = 0.824, P ≤ .0001), BODE PFSDQ-M (R² = 0.803, P ≤ .0001), and BODE HAP (R² = 0.500, P ≤ .0001).

Conclusion: 

The BODE TGlittre, and BODE PFSDQ-M may be used as alternatives to the 6MWT when physical space is not available to perform the 6MWT or when the condition of a patient does not allow performance of the 6MWT.

In Brief

We assessed the association between the original BODE and the BODE modified by replacing the 6MWT with the scores from the Pulmonary Functional Status and Dyspnea Questionnaire—modified version (PFSDQ-M), Human Activity Profile Test, and the Glittre ADL Test (TGlittre). The BODE TGlittre and BODE PFSDQ-M may be used as alternatives to the 6MWT.
