BackgroundHome-based monitoring and timely intervention of patients with acute coronary syndrome (ACS) and heart failure (HF) can improve patient outcomes. TeleClinical Care (TCC-Cardiac) is a smartphone app-based model of care designed to improve community-based care. We conducted a process evaluation within a multi-centre RCT to elucidate barriers and facilitators to implementation. Methods Patients were enrolled during their hospital stay and provided with an app and Bluetooth observation monitors. Patients were encouraged to engage with the app regularly (i.e. exercise program, record their observations). Data were monitored by a dedicated Remote Monitoring Solution team (RMS), and information was made available to the care team. Interviews were conducted with patients at 6 months, and with 3 RMS members, 2 HF nurses and 1 cardiologist. Results Of the 35 enrolled patients, 27 (77%) had a diagnosis of ACS and 8 (23%) of HF. Patient engagement with the app was good overall, with adherence tailing off over time, demonstrated by median (IQI) patient self-BP recordings of 93.3% (90-100%) at 1-month compared to 70% (43-90%) at 6-months. Older patients had higher levels of adoption (>50%), with a median age amongst high adopters of 67-years (IQI 40-82) compared to 63-years (IQI 50-87) for medium adopters (50-70%) and 44-years (IQI 33-53) amongst low adopters (
