Atrial fibrillation (AF) is a common, morbid condition with increasing prevalence. Poor health-related quality of life is common in AF. Patients experience debilitating symptoms and challenging adherence to long-term (possibly lifelong) anticoagulation. The increased risks of stroke, heart failure and mortality associated with AF persist even with optimal treatment. Morbidity in AF is further exacerbated by social factors. Limited health literacy carries challenges of learning a specialized terminology and navigating specialized treatments. In multiple cardiovascular diseases, self-care has demonstrated improvement in self-efficacy, health-related quality of life, symptom burden, and health care utilization - essential components of patient success with AF. Selfcare can provide the critical skills to navigate a challenging chronic disease and improve patient-centered outcomes. Delivery of self-care as a mobile health intervention can complement standard care with a longitudinal intervention to improve patient-centered strategies for AF. While self-care interventions for AF have focused foremost on self-monitoring of anticoagulation,self-care has demonstrated its potential to meet the "triple aim" of improved patient experience, reduced health care utilization, and lower costs.

Untreated hyperthyroidism or =3 months euthyroidism before inclusion; 7. Foreseen pacemaker, internal cardioverter defibrillator, or cardiac resynchronization therapy; 8. Cardiac surgery =3 months before inclusion; 9. Planned cardiac surgery; 10. Presence of non-cardiovascular conditions likely to be fatal within 12 months (e.g., cancer); 11. Inability to comprehend the study protocol, defined as failing to answer correctly a set of questions on orientation and short-term memory during the consent process. |

Primary | Proportion of Days Covered | Proportion of Days Covered (PDC), obtained from collection of electronic prescription and pharmacy fill data, and defined as the proportion of availability of medication for the period of interest, here the period from the date of the baseline to the 12-month examination. PDC range is 0 to 1.00 with higher values indicating greater proportion of days with medication over the 12-month period of study participation as indicated by pharmacy records. | 12 months | |
Secondary | Self-reported Non-adherence | Self-reported non-adherence to oral anticoagulation with a 3-item instrument with each item scored 1-5 and lower scores indicating adherence. Scores dichotomized to classify participants as adherent (indicated by reporting 1 on all 3 items) or as non-adherent (indicated by reporting = 2 on any of the 3 items). | 4, 8 and 12 months | |
Secondary | Patient-Reported Outcomes Measurement Information System (PROMIS)-29 | Measure Description: Patient-Reported Outcomes Measurement Information System (PROMIS)-29 assesses 7 domains (physical function; depression and sadness; pain interference; satisfaction with participation in social roles and activities; fatigue; anxiety and fear; sleep disturbance), 4 questions each, and Pain Intensity with a single item. The 7 domain scores are transformed using a T-score with a mean of 50, standard deviation of 10, in a referent population. Higher scores indicate worse health for the depression, pain, fatigue, anxiety/sleep domains, while higher scores indicate better health for the physical function and satisfaction domains. The single Pain Intensity item is scored 0 (No pain) to 10 (Worst imaginable pain) in the past 7 days.

Secondary | Atrial Fibrillation Effect on Quality of Life (AFEQT) | The Atrial Fibrillation Effect on Quality of life (AFEQT) is a widely used measure of atrial fibrillation-specific health-related quality of life. Scores range from 0 to 100 with higher scores indicating superior health-related quality of life in AF. | 4, 8 and 12 months | |
Secondary | Emergency Room (ER) Visits and Hospitalizations | The number of emergency room visits and hospitalizations quantified at 12 months. | 12 months | |
Secondary | Days of Hospitalization | The number of days of hospitalization ascertained from extraction of electronic health records through the 12 months of study duration. Total days spent in hospital over 12 months were summarized as a single count for each participant. | 12 months |
