The Impact of a Home-based Pulmonary Telerehabilitation Program in Acute Exacerbations of COPD

Pulmonary telerehabilitation programs have been shown to have a high acceptance and adherence rate and lead to improvement in exercise capacity and quality of life in stable COPD. However, data regarding the feasibility and impact of pulmonary telerehabilitation following hospitalization for an Acute Exacerbations of Chronic Obstructive Pulmonary Disease (AECOPD) on physical activity levels, muscle function, exercise capacity, and health‐related quality of life are lacking. The primary hypothesis is that a home‐based pulmonary telerehabilitation program initiated at hospital discharge following an AECOPD is feasible in the Veteran population and will result in increased physical activity and greater improvement in muscle function, exercise capacity, and health‐related quality of life compared to usual care. This hypothesis will be tested with the following specific aims: (1) To determine the feasibility of an eight‐week home‐based pulmonary telerehabilitation program in Veterans with moderate to severe COPD initiated in the immediate post‐hospitalization period following an AECOPD. (2) To determine physical activity levels and the magnitude and variability in changes of measurements of muscle strength, functional exercise performance, and health‐related quality of life following an eight‐week home‐based pulmonary telerehabilitation program versus usual care initiated in Veterans with moderate to severe COPD immediately following hospitalization for an AECOPD. The study will randomize (1:1 allocation) 30 male and female Veterans hospitalized with an AECOPD to either an eight‐week, three sessions per week, home‐based pulmonary telerehabilitation program that includes lower extremity endurance exercises with a cycle ergometer and upper and lower extremity strength training with 1:1 supervision via video conferencing with an exercise physiologist as well as a twice‐monthly online support group via video conferencing versus usual care. Changes from baseline in physical activity levels, handgrip and quadriceps muscle strength, exercise endurance, and health‐related quality of life will be assessed following the pulmonary telerehabilitation program versus usual care. Findings from this project will contribute to the growing field of pulmonary telerehabilitation and will provide critical preliminary data for the design and implementation of a larger, randomized control trial assessing the impact of pulmonary telerehabilitation on long‐term clinical outcomes following AECOPD.
