Key result
Mobile health intervention for post-rehab physical activity proves feasible with ~90% retention despite low recruitment.
Why the study?
To evaluate the feasibility of a mobile health-supported intervention to support maintenance of physical activity in patients with cardiovascular diseases after cardiac rehabilitation.
Is a 12-week mHealth intervention utilizing text messaging and behavior change techniques feasible for supporting maintenance of physical activity after cardiac rehabilitation?
Is a 12-week mHealth intervention utilizing text messaging and behavior change techniques feasible for supporting maintenance of physical activity after cardiac rehabilitation?
A 12-week mHealth intervention to support physical activity maintenance after cardiac rehabilitation is feasible and acceptable, though recruitment and response rates require optimization before larger efficacy trials.
Supports mHealth progression criteria in cardiac rehab; leaves open efficacy and scalable recruitment for future trials.
Objective: To evaluate the feasibility of a mobile health-supported intervention in patients with cardiovascular diseases after completion of a cardiac rehabilitation programme. Methods: The feasibility study was performed in two hospitals and one municipality in Region Zealand, Denmark. Eligible participants were ≥18 years old, participated in a supervised cardiac rehabilitation programme, had access to a mobile phone, and could walk 3 m independently. Participants received a 12-week intervention utilizing behaviour change techniques, consisting of action planning, text messages, and phone support. Feasibility was assessed using pre-defined progression criteria, which included recruitment (≥75%), retention (≥80%), accelerometer data completeness (≥80%), coordinator (phone support) time (≤30 min), the response rate on patient-reported outcomes (≥90%), adherence (≥75% respond to ≥75% of messages), and acceptability (≥75%). The secondary outcome of objective physical activity was assessed with accelerometers. Results: Ten women and 30 men with cardiovascular diseases aged 63.5 (±9.8 SD) participated. The progression criteria for retention (90%), accelerometer data completeness (83%), coordinator time (9.9 min), adherence (83%), and acceptability (82%) were at acceptable levels, exceptions were progression criteria for recruitment (35%) being below acceptable levels for recruitment, and response rate on patient-reported outcomes (75%). High satisfaction (92.6%) with the intervention was found. All objectively measured physical activity levels remained unchanged from baseline to follow-up. No serious adverse events related to the intervention were reported. Conclusion: Mobile health-supported maintenance of physical activity after cardiac rehabilitation completion was feasible, safe, and acceptable. Yet, changes to improve recruitment and response rate are needed before conducting a large-scale effect evaluation.

Hamborg et al. (2024) studied Cardiovascular diseases after cardiac rehabilitation (n=40). mHealth intervention (action planning, text messages, and phone support) was evaluated on Feasibility (recruitment, retention, accelerometer data completeness, coordinator time, response rate, adherence, and acceptability). A 12-week mobile health intervention to support physical activity maintenance after cardiac rehabilitation was feasible and acceptable, achieving 90% retention but only 35% recruitment.
