Brief Summary

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.

Outcome Measures

Primary Outcomes (1)

  • 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 Outcomes (5)

  • Self-reported Non-adherence

    4, 8 and 12 months

  • Patient-Reported Outcomes Measurement Information System (PROMIS)-29

    4, 8, and 12 months

  • Atrial Fibrillation Effect on Quality of Life (AFEQT)

    4, 8 and 12 months

  • Emergency Room (ER) Visits and Hospitalizations

    12 months

  • Days of Hospitalization

Eligibility Criteria

Age21 Years+
Sexall
Healthy VolunteersNo
Age GroupsAdult (18-64), Older Adult (65+)

You may qualify if:

  • Adult, age ≥21;
  • Diagnosis of AF, identified from the electronic health record problem list and confirmed by 2 or more reports of AF from separate monitoring events at least 2 weeks apart (electrocardiogram, Holter or event monitor);
  • CHA2DS2-VASc (heart failure, hypertension, age, diabetes, prior stroke or transient ischemic attack, coronary heart disease, female sex)≥2;
  • Prescribed use of warfarin or direct-acting oral anticoagulant for AF stroke prevention;
  • English-speaking well enough to participate in informed consent and this study;
  • No plans to relocate from the area within 12 months of enrollment.

You may not qualify if:

  • Conditions other than AF that require anticoagulation, such as mechanical prosthetic valve, deep vein thrombosis, or pulmonary embolism;
  • History of pulmonary vein isolation or foreseen pulmonary vein isolation;
  • History of atrioventricular nodal ablation or foreseen atrioventricular nodal ablation;
  • Foreseen pacemaker, internal cardioverter defibrillator, or cardiac resynchronization therapy;
  • Planned cardiac surgery;
  • Presence of non-cardiovascular conditions likely to be fatal within 12 months (e.g., cancer);
  • 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.
