Patient Centered Mobile Health Technology Enabled Atrial Fibrillation Management

Feasibility assessed by retention at 12 weeks (number of individuals who continue study participation (defined by App interaction, Coaching call participation or follow up survey completion)

Measured by Atrial Fibrillation Effect on Quality-of-Life (AFEQT), which consists of 20 items. Score ranges from 0 to 100 with higher scores signifying better quality of life.

Measured by the Atrial Fibrillation Severity Scale (AFSS) - validated 19 item questionnaire. Includes 5 subscores. AF burden is the sum of AF duration, AF severity, and AF frequency, and ranges from 3 to 30, with 30 being highest burden. AF duration, severity, and frequency each range from 1 to 10. The final subscore is AF symptoms, which ranges from 0-35 with 35 indicating worst possible symptoms.

Measured by Perceived Stress Score (PSS-10), 10 item questionnaire where score ranges from 0-40 with higher scores indicating higher level of stress.

Physical Activity will be assessed by The Rapid Assessment of Physical Activity (RAPA). Part 1 scores range from 1-5 with increasing scores indicating higher levels of activity, 5 being optimal. Part 2 is scored from 0-3 and measures the amount of flexibility and calisthenics exercise a person completes, with 3 being optimal.

As assessed by The Alcohol Use Disorders Identification Test (AUDIT), 10-item questionnaire. The score range is from 0 to 40 with 0 referring to abstainer with no history of alcohol abuse and higher scores indicate gradually higher and hazardous alcohol dependence.

Measured by Rate Your Plate (RYP) scale. A 27 item scale administered at 12 weeks with the following scoring system: Score ranges from 27-81.

Score of 27-45: There are many ways you can make your eating habits healthier. 46-63: There are some ways you can make your eating habits healthier. 64-81: Higher score indicates participant is making many healthy choices.

Measured in millimeters of mercury (mmHg).

Measured in kilograms over meter squared (Kg/m^2).

Measured by the System Usability Scale (SUS), modified for the intervention. The SUS score ranges from 0-100, where 0 is "worst imaginable" and 100 is "best imaginable." The average score is 68.0, a good score is between 71.4-85.4. 85.5 and above is considered excellent. Higher score more satisfaction.

Patients completed an at-home sleep study and received a diagnosis of no sleep apnea, mild sleep apnea, moderate sleep apnea, or severe sleep apnea, based on their AHI (apnea-hypopnea index). AHI is measured in breathing disturbance events per hour. An AHI <5 indicates no sleep apnea, from 5-15 is mild, 16-30 is moderate, and >30 is severe sleep apnea.
