Factors Associated With Acceptance of Home-Based Pulmonary Telerehabilitation in COPD

The participation decision recorded at screening will be classified as acceptance or refusal of the proposed 8-week home-based pulmonary telerehabilitation program. The number and percentage of participants in each category will be reported.

Reasons for refusal documented in the screening file or medical record will be coded retrospectively into descriptive categories and reported as numbers and percentages among participants with an available reason. More than one category may be assigned to a participant.

Distance from the residence recorded at screening to ADIR Association will be calculated using a standardized mapping procedure and expressed in kilometers. The derived value will be compared between participants who accepted and declined telerehabilitation.

The estimated duration of the fastest car journey from the residence recorded at screening to ADIR Association will be calculated using a standardized mapping procedure and expressed in minutes. The derived value will be compared between participation-decision groups.

Age in years at screening will be compared between participants who accepted and declined telerehabilitation.

The number and percentage of female and male participants will be reported for each participation-decision group.

Body mass index will be calculated as weight in kilograms divided by height in meters squared and compared between groups.

COPD severity available in the medical record, including Global Initiative for Chronic Obstructive Lung Disease (GOLD) spirometric grade when documented, will be reported by participation-decision group.

The number and percentage of participants receiving long-term oxygen therapy will be reported for each group.

Functional dyspnea will be assessed using the modified Medical Research Council (mMRC) dyspnea scale. Scores range from 0 to 4, with higher scores indicating greater dyspnea-related disability.

Respiratory quality of life will be assessed using the Visual Simplified Respiratory Questionnaire (VSRQ). Scores range from 0 to 80, with higher scores indicating better respiratory quality of life.

Respiratory quality of life will be assessed using the Saint George's Respiratory Questionnaire (SGRQ). Scores range from 0 to 100, with lower scores indicating better respiratory quality of life.

Anxiety symptoms will be assessed using the anxiety subscale of the Hospital Anxiety and Depression Scale (HADS-A). Scores range from 0 to 21, with higher scores indicating more severe anxiety symptoms.

Depressive symptoms will be assessed using the depression subscale of the Hospital Anxiety and Depression Scale (HADS-D). Scores range from 0 to 21, with higher scores indicating more severe depressive symptoms.

Functional exercise capacity will be expressed as the distance walked during the 6-minute walk test, in meters.

Functional exercise capacity will be expressed as the number of steps completed during the 6-minute stepper test.

Functional exercise capacity will be expressed as the number of complete repetitions performed during the 1-minute sit-to-stand test.

Peak oxygen uptake (VO2peak), when available, will be extracted from the most recent cardiopulmonary exercise test and compared between groups.

The number and percentage of participants with a previous pulmonary rehabilitation program will be reported for each group.

When available, the setting of previous pulmonary rehabilitation will be classified as center-based, home-based, telerehabilitation, private physiotherapy practice, hybrid or mixed, other, or unknown.

The most recent forced expiratory volume in 1 second (FEV1) available at the time of screening for the initial telerehabilitation study will be extracted from the medical record. FEV1 will be reported as an absolute volume in liters and as a percentage of the predicted value. Values will be compared between participants who accepted and those who declined participation in the home-based pulmonary telerehabilitation program.

The most recent forced vital capacity (FVC) available at the time of screening for the initial telerehabilitation study will be extracted from the medical record. FVC will be reported as an absolute volume in liters and as a percentage of the predicted value. Values will be compared between participants who accepted and those who declined participation in the home-based pulmonary telerehabilitation program.

The most recent ratio of forced expiratory volume in 1 second to forced vital capacity (FEV1/FVC) available at the time of screening for the initial telerehabilitation study will be extracted from the medical record. The FEV1/FVC ratio will be reported as a percentage. Values will be compared between participants who accepted and those who declined participation in the home-based pulmonary telerehabilitation program.

The most recent residual volume (RV) available at the time of screening for the initial telerehabilitation study will be extracted from the medical record. RV will be reported as an absolute volume in liters and as a percentage of the predicted value. Values will be compared between participants who accepted and those who declined participation in the home-based pulmonary telerehabilitation program.

The most recent total lung capacity (TLC) available at the time of screening for the initial telerehabilitation study will be extracted from the medical record. TLC will be reported as an absolute volume in liters and as a percentage of the predicted value. Values will be compared between participants who accepted and those who declined participation in the home-based pulmonary telerehabilitation program.

The most recent slow vital capacity (VC) available at the time of screening for the initial telerehabilitation study will be extracted from the medical record. VC will be reported as an absolute volume in liters and as a percentage of the predicted value. Values will be compared between participants who accepted and those who declined participation in the home-based pulmonary telerehabilitation program.
