Po-03-053 impact of patient access to atrial fibrillation burden data detected via insertable cardiac monitor

Although consumer technologies offer patients an opportunity to view their health metrics directly, cardiovascular implantable electronic device (CIED) data is not shared in this manner. Patient (mis)interpretation of data and the potential negative impact on patient perception of health status is often cited as a reason to limit direct access; however, quantified analysis regarding patient engagement with CIED data is scarce. To understand the frequency at which patients with an insertable cardiac monitor (ICM) view their atrial fibrillation burden data (AFB) and the impact that data access has on patient behavior, their concern about AF and engagement with their care provider. Patients with a LINQ or LINQ II ICM (Medtronic) indicated for suspected or known AF were provided access to their daily AFB, defined as total time in AF in a 24-hour window. Access was available via an experimental Medtronic Discovery app in cumulative 15-minute floored segments. Patients also received a remotely distributed voluntary survey via the app 180 days post enrollment. Of 207 patients who received the survey (mean age 69±10, 43% women) 112 (54%) responded after a mean of 185±6 days (age 68±10 years; 39% female). Only 11 (10%) patients reported reviewing their AFB data daily and 41 (37%) patients never accessed their AFB data (Figure 1a). Access to AFB did not induce any behavioral changes in 56 (50%) respondents (Figure 1b). Access to AFB data reduced patient-reported anxiety in 45 (40%) patients and increased patient-reported anxiety in only 7 (6%) patients. Finally, while access to AFB data did not change the frequency with which patients contacted their provider in 84% of cases, 64% of patients reported more informed conversations with their provider. We found patients provided access to ICM based AFB access the data judiciously and that it does not result in large behavioral changes, increased patient-reported anxiety or necessitate increased contact with care providers. However, two-thirds of patient reported more informed conversations with their providers, suggesting access provides patients greater agency over their health.
