Precision Atrial Fibrillation App to support Atrial Fibrillation Management

We will develop and pre-test an interventional iOS & Android Precision AF App designed to help participants with a diagnosis of AF to learn more about their disease and provide the cardiologist feedback on patient's rhythm and risk factors. The app will consist of two levels (Levels 1 and 2), over the course of 24 weeks. During the initial two-week ‘onboarding period’ (Level 1) AF education will be provided and data will be gathered to set an individual foundation; followed by 22 weeks of active tracking and intervention (Level 2). The Precision AF App designed by cardiologists, exercise physiologists, nutritionists and precision health leaders will help improve and better manage atrial fibrillation (AF). The app provides resources on AF and guides on healthy lifestyle and provides tailored exercise programs. The resources in the App for AF knowledge, risk factor management, exercise and lifestyle change have been specifically designed for the study. There are 16 videos specifically created for the App. However, the participants are also directed to freely available resources on the website of Heart Foundation, Australia. Once enrolled in the study, the participant will be instructed to download the smartphone application (Precision AF App). Upon installing the app they will be given a unique code to access the app. Once the participant has accessed the app they will be taken through a process which includes instructions on App usage and following Bluetooth devices. KardiaMobile App (supports KardiaMobile ECG Device), Smart Scale and Blood Pressure Monitor). The Bluetooth devices, KardiaMobile ECG Device, Smart Scale and Blood Pressure Monitor, will be provided to participants as part of the study. The participant will also be asked to track their food choices and alcohol intake through the Precision AF App. Further visual guides (images/documents) and videos and/or links to dietary support will be incorporated in the app. Regular self-reported physical activity (at baseline (first week of level II) and then repeated every 4 weeks (weeks 5, 9, 13, 17, 21), alongside the participants daily recorded step counts will be captured. Based on the participants level of fitness they will be assigned to one of three predefined exercise categories: light; moderate or vigorous intensity. The fitness level will be determined based on a proprietary algorithm being developed as part of the App. The frequency and duration of exercise will be suggested based on their assessed activity category. The predominant exercise is walking. Resistance exercises are suggested for participants with high levels of fitness. Exercise videos on how to increase amount of walking, safety, and monitoring are all incorporated in the form of proprietary educational videos. The participants can contact the research team through the App with queries, that will be answered by an exercise physiologist specialised in AF management. The data from the smart scale and BP measurements will be automatically pulled into the App. The data from Withing mats and Kardiamobile will be automatically imported through an API into the RedCap database. The data from the App is automatically imported into the backend and RedCap which will be monitored every 2 business days. The data on each aspect of the usage of the App e.g.. video viewing will be captured and analysed. There is provision to contact participants and their treating cardiologist based on information collected. The treating cardiologist will have access to the information at the backend of the App.
