The Heartline Experience: Achieving Long-Term Participant Engagement in Digital Health Technology Trials
Authors' conclusion
Study adherence in Heartline was high and sustained through 2-year follow-up, using a purposely designed engagement program delivered by a mobile app. Participants in this older population remotely and regularly submitted study information through the app and reported high study satisfaction (A Study to Investigate if Early Atrial Fibrillation [AF] Diagnosis Reduces Risk of Events Like Stroke in the Real-World; NCT04276441).
