Background: Chronic Obstructive Pulmonary Disease (COPD) is characterized by signs and symptoms that limit the performance of activities of daily living and impact on aerobic capacity that affect the health-related quality of life (HRQoL). Therefore, there is a growing interest in determining the possible relationships between these aspects.
Purpose: To determine the statistical relation between aerobic capacity, symptoms and health-related quality of life in patients with a medical diagnosis of COPD who attend a pulmonary rehabilitation program.
Methods: A cross-sectional study, 36 patients with COPD who entered a pulmonary rehabilitation program. They performed the 6-minute walk test (6MWT) and answer the Saint George Respiratory Questionnaire (SGRQ) and the Spanish Self-Administered Version of the Chronic Respiratory Disease Questionnaire (CRQ-SAS). Qualitative variables are presented in percentages, quantitative variables are presented in average ± standard deviation. Correlations were made using the pearson method between the distance traveled in the TC6M and the domains of the health-related quality of life questionnaires CRQ-SAS, SGRQ and mMRC having a statistically significant value less than 0.05.
Results: 36 patients, mean age of 71.9 ± 7.1; mostly men with 83.3%. There was a good correlation between the TC6M and mMRC dyspnea (r = -0.586). Regarding the relation with the HRQoL, a p-value <0.05 was obtained in the CRQ questionnaire; emotional, fatigue and total domains. With the SGRQ, no correlation was found.
Conclusion(s): This study found that there is a good statistical relationship between 6MWT and symptoms in the CRQ Questionnaire.
Implications: COPD patients linked to pulmonary rehabilitation programs could be evaluated more specifically in their quality of life, in addition to showing key outcome variables at the time of completing pulmonary rehabilitation.
