This study found digital cardiac rehabilitation (CR) feasible and acceptable, though modifications to education and feedback components are needed. Further research will optimize this digital CR intervention for broader reach.

Area of Science:

  • Cardiology
  • Digital Health
  • Rehabilitation Medicine

Background:

  • Cardiac rehabilitation (CR) is crucial but underutilized globally.
  • Digital CR offers a scalable alternative to traditional center-based programs.
  • Optimizing digital CR requires understanding the effectiveness of its individual components.

Purpose of the Study:

  • To explore the feasibility and acceptability of a factorial design for digital CR.
  • To prepare for a randomized controlled trial optimizing digital CR interventions.
  • To evaluate the implementation of multiple intervention components in a digital format.

Main Methods:

  • A 2^3 factorial trial randomized 8 participants to 8 conditions over 6 weeks.
  • Intervention components included goal setting/self-monitoring, education, and feedback messages.

  • Feasibility assessed via fidelity and data completeness; acceptability via usability scales and interviews.

    • Main Results:

    • The digital CR intervention showed good usability and was generally acceptable to participants.
    • Feedback messages were less acceptable (50%); education fidelity was lower.
    • Participants desired more tailored feedback and two-way communication.

    Conclusions:

    • Implementing a factorial design for digital CR is feasible.
    • Modifications to education and feedback components are required before a pilot RCT.
    • This research paves the way for optimizing digital CR interventions.
