  • Does Activity Feedback Increase ICD Patient Activity Levels? Samuel F. Sears, PhD, East Carolina University Abstract: The implantable cardioverter defibrillator (ICD) uses shock therapy to prevent mortality amidst potentially life-threatening ventricular arrhythmias. Despite significant reductions in all-cause mortality, a substantial number of ICD patients experience psychosocial distress and activity avoidance, resulting in diminished quality of life (QOL). Over 50% of ICD patients regularly avoid daily household activities, sexual activities, and moderate intensity recreational activities in an apparent effort to prevent ICD shocks. Activity avoidance does not prevent ICD shocks, but often results in a cycle of less activity, increased shock anxiety, poor acceptance of the ICD device itself, and decreased QOL. Modern technological activity monitoring allows for an objective assessment of ICD patient activity at low cost. The commercially available device, Fitbit, provides wireless fitness information about activity levels that could be coupled with activity data from the ICD itself to facilitate optimal levels of re-engagement in daily life. Targeting patient activity using tailored and objective activity data has not been systematically studied in ICD patients. This study will provide guidance on ?best practice? for the role of activity measurement and ICD patient coaching to facilitate optimal ICD patient daily activity and enhance QOL outcomes. A longitudinal, randomized two-group, mixed design with follow-up is planned for this project to address the study?s main objective ? i.e., determine the potential and relative values of activity feedback and coaching in facilitating ICD patient activity level following ICD implantation. An active intervention of coaching and activity feedback will be administered to one group while the control group receives Usual Care. In addition to collecting data about patient activity through the ICD and the FitBit devices, additional outcomes concerning patient well-being and QOL will be measured as well.
