Effectiveness of home-based exercise in older patients with advanced chronic obstructive pulmonary disease: A 3-year cohort study
Aim
To determine whether homeâbased exercise can improve clinical outcomes in older patients with advanced chronic obstructive pulmonary disease using longâterm oxygen therapy.
Methods
Information was provided to improve chronic obstructive pulmonary disease selfâmanagement before the onset of the present prospective 3âyear cohort study. Patients selected either homeâbased exercise using a lowerâlimb cycle machine (ergoâbicycle; group E), or usual exercise (group U). To assess selfâmanagement, the Lung Information Needs Questionnaire was evaluated every 6 months. Clinical outcomes included the 6âmin walk test, pulmonary function tests, the body mass index, airflow obstruction, dyspnea and exercise index, St. George's respiratory questionnaire, and the number of exacerbations and hospitalizations.
Results
A total of 136 patients (group E = 72; group U = 64), with a mean age of 74.2 years were enrolled. Total Lung Information Needs Questionnaire scores improved over 3 years for group E (P = 0.003). The distance of the 6âmin walk test was well maintained in group E, but significantly decreased in group U (P < 0.001). The percentage of forced expiratory volume in 1 s at baseline was lower in group E (P = 0.016), but was maintained over 3 years, whereas a significant reduction was seen in group U (P = 0.001). The body mass index, airflow obstruction, dyspnea and exercise index significantly worsened in both groups over 3 years (group E: P = 0.011; group U: P < 0.001), whereas a significant decrease in the number of exacerbations was noted in group E (P = 0.009).
Conclusions
Patients who undertook homeâbased exercise using an ergoâbicycle were able to maintain clinical outcomes including 6âmin walk test distance and percentage of forced expiratory volume in 1 s predicted, and recorded fewer exacerbations over 3 years
