- Registration Number
- NCT03084458
- Lead Sponsor
- Ashley Burch
- Brief Summary
Medical device technology for use by patients is gaining popularity. Modern cardiac disease management seeks to integrate multiple device technologies and capabilities to optimize health outcomes. Fitbit, Inc. manufactures a line of wireless-enabled activity, wearable trackers that are used in conjunction with a mobile device. The Fitbit trackers use three-dimensional accelerometers to sense and record movement. This technology represents a new frontier for patients and their health care providers to understand and track physical activity in real time. The primary aim of the current project is to assess whether activity feedback using FitBit technology affects implantable cardioverter defibrillator (ICD) patient activity level as measured by the ICD accelerometer. The investigators will also examine the perceived added value of Fitbit technology to an ICD patient user experience.
Approximately 50 participants will be recruited. Participants in the experimental group (n = 25) will use the Fitbit device for 12 weeks. The experimental group will receive fitness goals (number of steps per day) to increase activity from a baseline value to a minimum of 7000 steps per day by week 9 of the intervention. Both groups will receive weekly texts messages to encourage activity. Feedback about technology satisfaction, cardiac anxiety, cardiac self-care, and health care utilization will be elicited from patients at multiple time points. Additional information will be gained about patient decision-making as participants may elect to continue Fitbit use beyond the study period; this will allow for behavioral evidence of the perceived value of adding this technology.

Group Intervention Description Fitbit Fitbit Same as control condition. In addition, participants in the experimental group will receive a Fitbit device with full instructions and troubleshooting. These participants will be given daily step goals, which will be increased during the course of the study, and be able to monitor their progress using the Fitbit app.
- Primary Outcome Measures
Name Time Method Does increased access to information on daily activity level (FitBit) increase device (ICD) coded total activity (step count) over usual care? 12 weeks At the final study visit, the ICD will be interrogated. Accelerometer data will be captured and used as a precise measure of physical activity, specifically, steps per day.
Analyses will be conducted to determine activity (step count) changes between groups and over time.Does activity level feedback have a greater impact on Quality of Life (QOL) than usual care? Indices of QOL will be multiple questionnaire scores entered together in a single analysis. 12 weeks Questionnaires that will be used include: Cardiac Anxiety Questionnaire, Duke Activity Status Index, Fitbit Technology Satisfaction, Florida Patient Acceptance Survey, Florida Shock Anxiety Scale, Patient Health Security, Self-Care of Heart Failure Index, and the Short-Form 12 Health Survey. Analyses will be conducted to determine quality of life changes between groups and over time from the baseline, month 1, and month 3 visits.
