Trial Outcomes & Findings for The Impact of a Home-based Pulmonary Telerehabilitation Program in Acute Exacerbations of COPD (NCT NCT03997513)

NCT ID: NCT03997513

Last Updated: 2024-07-05

Results Overview

Quadriceps muscle maximal force (kilogram-force, kgf) will be measured with a Keiser leg press. One repetition maximum (1RM) measures will be obtained by progressively increasing resistance until the participant is unable to successfully complete one repetition. Peak muscle power will be measured at 40, 50, 60, 70, 80, and 90 percent of the 1RM 30 minutes after the 1RM measurement was obtained.

Pulmonary Telerehabilitation Intervention Group
The intervention will consist of an eight-week, three sessions per week, home-based pulmonary telerehabilitation program that will incorporate both lower extremity endurance exercise and upper and lower extremity resistance training. Subjects randomized to the study intervention will also participate in a one hour, twice-monthly support group via group video conferencing consisting of an educational topic (i.e. inhaler use, understanding COPD) and group discussion.

Usual Care Group
Participants randomized to the usual care arm will also be enrolled in our institution's telehealth program, will receive an automatic blood pressure monitor, portable pulse oximeter, and scale and will be in regular contact with a telehealth provider. A study team member will meet with participants randomized to the usual care arm to discuss the importance of exercise and will encourage exercise (strength training, light aerobic activity such as walking or cycling) a minimum of 20-40 minutes three times per week at discharge.

PRIMARY outcome

Timeframe: measured at baseline and at ten weeks

Population: This test was not performed due to COVID restrictions at the VA and inability to use the testing equipment.

Quadriceps muscle maximal force (kilogram-force, kgf) will be measured with a Keiser leg press. One repetition maximum (1RM) measures will be obtained by progressively increasing resistance until the participant is unable to successfully complete one repetition. Peak muscle power will be measured at 40, 50, 60, 70, 80, and 90 percent of the 1RM 30 minutes after the 1RM measurement was obtained.

Outcome measures

Outcome data not reported

PRIMARY outcome

Timeframe: measured at baseline and at ten weeks

Population: One participant in the intervention group declined six minute walk testing at the baseline and follow-up visit. The difference in walk distance from baseline to 10 weeks was compared between groups.

Participants completed a six minute walk test, which consisted of walking in a flat corridor for six minutes with the distance walked measured in feet. Participants were instructed to complete the walk using their home oxygen prescription for exertion. The difference between baseline and ten week walk test was compared between groups.

PRIMARY outcome

Timeframe: measured at baseline and ten weeks

Population: This questionnaire was not used.

Health-related quality of life will be assessed with the Short-Form 36-Item Questionnaire (SF-36) prior to hospital discharge and at ten weeks following an eight week pulmonary telerehabilitation intervention or usual care. The SF-36 consists of 36 questions spanning nine health domains and is a valid measure of health-related quality of life in COPD that is responsive to change following a pulmonary rehabilitation intervention.

Outcome data not reported

PRIMARY outcome

Timeframe: measured at ten weeks (study completion)

Population: Participants randomized to the pulmonary telerehabilitation intervention group

Participants will be administered a survey by the study coordinator at ten weeks after completion of the eight-week pulmonary telerehabilitation intervention that will require them to respond to statements related to their satisfaction with the home-based program. Statements will address ease of use of the video conferencing modality, acceptability of exercise components, perceptions of impact on muscle strength and exercise endurance, and willingness to participate in additional pulmonary telerehabilitation. Participants randomized to the usual care group will not be administered a survey.

SECONDARY outcome

Timeframe: measured at baseline and ten weeks

Population: the change in sit to stand count in 30 seconds from baseline to ten weeks between the intervention and usual care group were compared

The one-minute sit-to-stand test has been shown to be reliable, valid, and responsive to change in exercise capacity following pulmonary rehabilitation in individuals with COPD. The test consists of the participant standing at full leg extension from a sitting position at their own pace as often as possible during a one minute testing interval. The participant is permitted to stop at any time during the one minute interval if necessary. An armless chair is used for testing and the participant is asked to fold their arms across their chest during testing. Two tests will be performed on separate days prior to discharge and the test with the greatest number of repetitions will be used as the baseline performance measure. A third test will be performed at ten weeks following an eight week pulmonary telerehabilitation intervention or usual care.

Population: change in handgrip strength from baseline to ten weeks compared between groups

Handgrip strength of the dominant hand will be measured with a hand dynamometer. Three measurements will be taken with a 60 second recovery period between trials. The average maximal force across trials will be calculated as the final handgrip strength.

Population: change in SGRQ score from baseline to ten weeks compared between groups

The St. George's Respiratory Questionnaire (SGRQ) is a disease-specific questionnaire validated to measure health status in patients with COPD. Total SGRQ scores range from 0-100 with higher scores indicating greater symptoms burden. The minimal clinically important difference is a difference of four points in the total SGRQ score.
