Methods utilised in this process evaluation.

Aim	Sub-aim	Method of data collection
1. To identify methods to maximise patient, team member and site participation in preparation for the large, multi-centre TCC-Cardiac trial	Analysis of screening and recruitment (reach)	A database of patients screened for enrolment was compared against a list of patients and their coded diagnoses provided by the data management team at the respective hospitals, according to the Australian Coding Standards (13).
	An analysis of the training and overall experience of team members	Semi-structured interviews with four team members
	Creation of a checklist to assess any new trial site prior to involvement in TCC-Cardiac	- Lead investigator's own experience - Semi-structured interviews with four team members
2. To identify the contextual factors that influenced the success of the TCC program	CR for ACS patients	CR attendance and completion rates were calculated for each site, for patients enrolled in the trial two months before the cessation of cardiac rehab due to COVID-19 (March 2020).
	HFOS	At recruitment, TCC team members documented if the patient was known to, or referred to, the local HFOS.
	Post-discharge cardiologist consultation	An audit of 20 discharge summaries from each site was conducted to identify the timing of post-discharge cardiologist appointment. The cardiologist offices were contacted to confirm if follow up occurred. If a follow-up range was given, then the longest duration within the range was defined as the prescribed follow-up interval (e.g., “4–6 weeks” would translate as 42 days).
3. To evaluate and explore the engagement of GPs and cardiologists with the TCC model of care and KIOLA server	Identifying attitudes of GPs and cardiologists	- Timestamps from KIOLA records to confirm the number of GPs who accessed the platform. - Semi –structured interviews with three GPs and three cardiologists.
4. To identify the impact of TCC participation of patient self-management and their overall rating of the app	Analysis of quotes from patients regarding a possible improvement of self-care due to TCC	All patients in the intervention arm were asked to complete a questionnaire regarding their experience. Within the questionnaire were the questions “what did you like the most about the TCC app” and “in what ways do you feel like the TCC app benefited you” and responses were reviewed for self-care references. The average overall patient rating out of 5 was calculated.
