Patients perspectives on integrating eHealth in regular care pathways for atrial fibrillation: evaluating photoplethysmography for remote self-assessment

Aims: Smartphone applications for heart rate and rhythm assessment are increasingly used for the management of atrial fibrillation (AF). Although the use of a photoplethysmography (PPG)-based smartphone application with subsequent (tele)consultations for AF management has been proven feasible in the TeleCheck-AF project, specific needs, and expectations of patients with AF are unclear. The aim of this study is to evaluate patients' perspectives on the use of remote PPG-based electronical health (eHealth) integrated in regular care pathways for AF.

Methods and results: A qualitative study was conducted among patients with known AF, who have used a PPG-based smartphone application around scheduled (tele)consultations. Semi-structured interviews were audio-recorded and transcribed verbatim. Data were analysed according to conventional content analysis.In total, 14 patients were interviewed. Five main themes were defined after analysis, i.e. smartphone application usability, requirements for eHealth implementation, remote self-assessment, patient engagement, and blended care (i.e. combining digital and face-to-face care). Overall, the participants were positive about the use of the PPG-based smartphone application and subsequent (tele)consultation. Using this application made the participants feel involved and led to active participation. In addition, the healthcare provider-patient relationship appeared an important aspect for adequate implementation. Particularly, timely consultation was found important, to discuss the results with their healthcare provider.

Conclusion: The results of this study emphasize the importance of blended care for the implementation of remote PPG-based eHealth in AF management. The use of a PPG-based smartphone application in regular care can support patient engagement and subsequently the process of shared decision making.
