Veterans With COPD Improve After 12-Week Telehealth Rehab
Pulmonary rehabilitation via telehealth was associated with improved walking distance and quality of life in veterans with COPD.
TOPLINE: Veterans with chronic obstructive pulmonary disease (COPD) who had follow-up outcome data after completing a 12-week telehealth pulmonary rehabilitation program had improved functional capacity, with 6-minute walk distance increasing by 41.3 m (15.7%) and quality-of-life scores improving by 27.9% to 42.7%. The virtual program had an 86% completion rate, suggesting telehealth rehabilitation may be a feasible alternative to traditional in-person programs.
METHODOLOGY:
A 12-week single-arm cohort intervention evaluated effectiveness, acceptability, and feasibility of in-home, supervised telehealth pulmonary rehabilitation delivered via US Department of Veterans Affairs (VA) Video Connect in Houston, Texas.
Participants included 51 veterans with COPD aged ≥ 18 years and referred to the program; exclusions included mobility-limiting surgery, neurologic disease impairing walking, likely nonadherence, or unwillingness to consent.
Intervention consisted of 1 session weekly for about 120 minutes led by a licensed physical therapist and respiratory therapist, with home monitoring of blood pressure, heart rate, SpO₂, respiratory rate, and exertion.
In-person outcome assessments occurred at baseline and 12 weeks; the primary outcome was the 6-minute walk test, and secondary outcomes included Timed Up & Go test, Five Times Sit-to-Stand test, and quality of life via the St. George’s Respiratory Questionnaire and COPD Assessment Test.
TAKEAWAY:
Functional capacity improved significantly with a mean increase of 41.3 m in 6-minute walk distance, a 15.7% improvement (P < .001; d = 0.76), surpassing the minimal clinically important difference of 25 m for patients with COPD.
COPD-affected quality of life improved, with St. George’s Respiratory Questionnaire scores decreasing by 18.2 points, a 27.9% improvement (P < .001), and COPD Assessment Test scores decreasing by 12.1 points, a 42.7% improvement (P < .001).
Functional mobility and lower-body strength also improved, with Timed Up and Go test completion time decreasing by 1.2 seconds (9.9% faster; P = .02) and Five Times Sit-to-Stand test time improving by 1.2 seconds (9.0% faster; P = .02).
Program retention was high, with 44 of 51 participants (86.3%) completing the full intervention. When excluding COVID-19 pandemic–related dropouts, the retention rate increased to 90.2%
IN PRACTICE: “Our study not only highlights the effectiveness of pulmonary rehabilitation in improving the functional performance of COPD patients but also emphasizes the potential use of telehealth-rehabilitation as a viable alternative to traditional in-clinic programs,” the authors wrote.

LIMITATIONS: According to the authors, the study lacked a control group and included predominantly male participants, which may limit generalizability. The modest sample size and insufficient exploration of potential confounding factors further constrain the generalizability of findings. Additionally, the study was limited to veterans living within 80 miles of Houston, creating an unusual proximity requirement for telehealth programs that could introduce selection bias. The researchers noted that actively recruiting during the COVID-19 pandemic presented unforeseen challenges, and the absence of remote biomechanical data collection may have limited the ability to monitor rehabilitation progress and make necessary adjustments.
