Is videoconference pulmonary rehabilitation associated with improvements in knowledge in people living with COPD? A...

Introduction: Pulmonary rehabilitation (PR) services are increasingly using alternative programme delivery modes, for example telerehabilitation strategies including videoconferencing, to improve patient choice and accessibility. Although telerehabilitation results in improvements in core outcomes, the effect on knowledge attainment is not known. Aim: To observe the real-world responses of patients choosing to undergo videoconference PR to a matched control group choosing to undergo in-person PR, in terms of knowledge attainment. Methods: Using propensity score matching, 25 people with COPD who completed videoconference PR were matched 1:1 with a control group of 25 people with COPD who completed in-person PR. Knowledge attainment was measured using the Lung Information Needs Questionnaire (LINQ). Results: There was a statistically and clinically significant improvement in LINQ score in both groups (mean (95%CI): videoconference -3.2 (-4.7 to -1.6); in-person -3.0 (-4.5 to -1.4)), with no significant between-group difference (mean (95%CI): 0.2 (-2.0 to -2.4)). 76% and 80% of participants achieved the minimal important difference of the LINQ in the videoconference and in-person PR groups respectively. Conclusion: In conclusion, this real-world service evaluation indicates that videoconference PR may be associated with similar improvements in knowledge attainment as in-person PR, but this requires corroboration due to the small sample size.
