Hybrid Virtual Coaching and Telemonitoring in COPD Management: The CAir Randomised Controlled Study
Objective
The goal of this study was to see how effective 12 weeks of hybrid virtual coaching is for improving the health-related quality of life (HrQoL) in stable COPD patients.
Methods
All patients received a CAir Desk for telemonitoring. The intervention group also got hybrid virtual coaching via a smartphone. This program included:
- Educational content
- Physical activity coaching
- Home-based exercises
The main outcome measured was HrQoL using the SGRQ. Additional outcomes included symptom burden, physical activity, functional exercise capacity, and lung function. We used linear regression to analyze differences between groups while accounting for initial variations.
Results
We included 30 COPD participants (13 women and 17 men, average age 63). A total of 24 (80%) completed the study. The results showed:
- Both groups improved in HrQoL (intervention: -4.5 points; control: -2.7 points), but there was no significant difference between the groups.
- Physical activity increased only in the intervention group (average increase of 2147 steps), which is clinically relevant but not statistically significant.
- Symptom burden decreased in both groups, with the intervention group showing a larger clinically relevant reduction.
Conclusion
The 12-week hybrid virtual coaching did not significantly improve HrQoL compared to telemonitoring alone in stable COPD patients. However, those who received coaching showed more improvement in physical activity and symptom burden.
