Abstract:

Virtual pulmonary rehabilitation (PR) is a proven yet underutilized intervention in COPD patients. However, the safety nor the effectiveness of virtual PR is established for patients with advanced disease and higher disease severity, particularly those requiring supplemental oxygen. We performed a retrospective review of 167 patients to evaluate the feasibility, safety, and effectiveness of virtual PR in oxygen-dependent versus non-oxygen-dependent COPD patients. Our primary outcome, attendance was high (88% of sessions were attended by both groups). Adverse events occurred in only 2 (1%) participants, 1 in each group. Both groups showed significant post-intervention improvements in dyspnea and depression scores (CAT, mMRC, PHQ-9) and functional exercise capacity (1MSTS), with the improvements approaching or exceeding the established minimal clinically important difference (MCID) values. When comparing the oxygen-dependent and non-oxygen groups, there were no significant differences in the degree of improvement for CAT, PHQ-9, and 1MSTS. For mMRC, those on oxygen did improve by 0.3 less than those not on oxygen (P = 0.052). These findings suggest virtual PR is safe and effective for COPD patients requiring oxygen. To our knowledge, this is the first study to compare outcomes of virtual PR in patients on and off oxygen. Future research should explore patient-specific factors that can further individualize care.
