OnBehalf TeleCheck-AF Investigators Aims TeleCheck-AF is a multicentre international project initiated to maintain care delivery for patients with atrial fibrillation (AF) during COVID-19 through teleconsultations supported by an on-demand photoplethysmography-based heart rate and rhythm monitoring app (FibriCheck®). We describe the characteristics and experiences from recruited patients. Methods Self-reported patient characteristics were obtained from the app. A survey exploring patient experiences completed by 826 patients. Results Within 28 weeks, 1930 AF patients were recruited by 38 centers in 14 countries, mainly for remote AF control (31% of patients) and AF ablation follow-up (42%). One-third of patients was in the age range 60-69 years. The most common comorbidity was hypertension (42% of all patients). More than 70% of patients were treated with oral anticoagulation. In total 59.858 heart rate and rhythm measurements were recorded. During the one-week FibriCheck® use, patient adherence was high. Patients performed between 2 and 5 recordings a day and the median number of measurements per patient was 21 [15-29]. The highest average number of measurements per patient was seen in patients older than 80years of age. Patients agreed that the FibriCheck® app was easy to use (94%) and easy to install (89%). The app gave patients a safe feeling (74%) due to being in constant heart rate and rhythm control. More than half of the patients (58%) agreed or strongly agreed that they would like to use the FibriCheck® app in the future. They also found the automated reminders useful (64%). Conclusions In the TeleCheck-AF project, mHealth adherence was high, particularly in older patients ≥80 years. The app FibriCheck® is easy to use for 7 days before a scheduled teleconsultation. Patients think that remote rate and rhythm monitoring around teleconsultation by the TeleCheck-AF approach may be an alternative to traditional face-to-face consultations in the future.

ZusammenfassungBasierend auf der Technologie der Photoplethysmographie (PPG) lässt sich mit der Kamera eines Smartphones das Vorliegen von Herzrhythmusstörungen und die Herzfrequenz valide erfassen. Diese Technologie wurde im Rahmen des TeleCheck-AF-Projektes benutzt, um die effektive Durchführung von Telekonsultationen bei Patienten mit Vorhofflimmern zu ermöglichen. Die vorliegende Arbeit soll eine Übersicht über die PPG-Technologie und eine Schritt-für-Schritt-Anleitung für die Analyse und Interpretation der PPG-Signale bieten. Damit soll eine Integration und Implementierung dieser vielversprechenden und weit verfügbaren Technik in den klinischen Alltag gebahnt werden.

OnBehalf TeleCheck-AF Investigators Aims Herein we describe the characteristics, inclusion rates and experiences from participating centres in the European TeleCheck-AF project. TeleCheck-AF is a multicentre international project initiated to maintain care delivery for patients with atrial fibrillation (AF) during COVID-19 through teleconsultations supported by an on-demand photoplethysmography-based heart rate and rhythm monitoring app (FibriCheck®). Methods Two surveys exploring centre characteristics (n = 25) and centre experiences (n = 23) were completed. Results Most centres were academic (64%) and specialized public cardiology/district hospitals (36%). Majority of centres had AF outpatient clinics (64%) and only 36% had AF ablation clinics. The time required to start patient inclusion and total number of included patients in the project was comparable for centres experienced (56%) or inexperienced in mHealth use. Within 28 weeks, 1930 AF patients were recruited, mainly for remote AF control (31% of patients) and AF ablation follow-up (42%). Average inclusion rate was highest during the lockdown restrictions and reached a steady state at a lower level after easing the restrictions (188 vs 52 weekly recruited patients). Majority (>80%) of the centres reported no problems during the implementation of the TeleCheck-AF approach. Centres agreed that the on-boarding process of their center in the TeleCheck-AF project was simple and access to the patients measurements via stand-alone cloud infrastructure was trouble-free and possible from the first day on. They also agreed that remote heart rate and rhythm assessment by the FibriCheck® app around teleconsulatation supported their medical decision making; that their patients responded positively to use FibriCheck® for seven days; and that they felt comfortable to interpret PPG recordings. Conclusions Despite different health care settings and mHealth experiences, the TeleCheck-AF approach could be set up within an extremely short time and easily used in different European centres during COVID-19.
