Intervention/exposure
Study type
Interventional
Description of intervention(s) / exposure
The intervention group will have access to a 6-month intervention that enables peer support via an interactive mobile application (app). Participants will be able to access the app down download from their personal mobile device. The intervention includes online peer discussion groups via discussion board (e.g., exercise and diet) in the app, access to digital educational resources (web-based information such as text, images, and videos), and facilitated conversations with health professionals (e.g., cardiac nurse, physiotherapist, dietician etc.). All participants will have access to all discussions and groups within the CVD community. Health professionals will be joining into the discussion groups periodically, post educational resources, as well as facilitate conversations with participants. The facilitated discussions will be online and likely less than a few minutes in duration on each occasion, however duration will vary and will be generic in nature with anything substantial in medical information requirements, the participants will be encouraged to discuss more fully with their general practitioners or other personal health provider. There will be no specific number of times per week required, however, participant will be encouraged to use the app as many times as they want. Adherence and engagement with the app will be monitored through analytic report provided by the app company (e.g., user session time, login tracker, engagement etc.).

Study design
Purpose of the study
Educational / counselling / training
Allocation to intervention
Randomised controlled trial
Procedure for enrolling a subject and allocating the treatment (allocation concealment procedures)
Allocation sequence will be concealed. An independent statistician will generate the randomisation schedule by computer (then upload into the study REDCap) with allocation sequence concealment strategies implemented. Lead investigator, participants, statisticians, and research assistants collecting data will be blinded to the order of group allocation.
Methods used to generate the sequence in which subjects will be randomised (sequence generation)
Computer-generated random allocation sequence

Statistical methods / analysis
Analyses will be performed according to the intention-to-treat principle by a statistician blinded to group allocation. Baseline and outcome data will be presented as frequencies and proportions for categorical data, and means and standard deviations (SD) for normally distributed continuous outcomes or median and interquartile intervals for skewed continuous outcomes. Outcomes will be compared between control and intervention groups using all available data with intervention and control groups compared at 6 and 12 months. Normally distributed continuous outcomes will be analysed using the analysis of covariance (ANCOVA) and categorical outcomes will be compared using a log-binomial regression model, adjusting for baseline value of the outcome variable. Pre-specified sub-group analyses will be performed for (i) gender, (ii) reginal areas, (iii) cardiac rehabilitation completion versus not and (iv) previous or current peer support attendance versus not. The subgroups will be compared by including an interaction term between the subgroups and the randomisation status to the main models.

Summary
Brief summary
Heart2Heart is a community-based randomised controlled trial with 12 months follow-up. The aim of the study is to determine whether implementation of a digital peer support program for people living with CHD is effective in improving social connectedness, clinical and patient-reported outcomes and experience measures. The intervention group will have access to a 6-month intervention that enables peer support via an interactive mobile application, which includes online discussion groups, access to resources and facilitated conversations with health professionals. If effective, the digital peer support intervention has the potential to increase social connectedness and empower people to self-manage and support others through sharing lived experience and learning.
