KardiaMobile ECG Monitoring Effects on Health Care Utilization and Patient Experience With Atrial Fibrillation

Study Overview
=================
Brief Summary
-----------------
This is a two-center, randomized controlled trial of 100 patients comparing intervention (KardiaMobile) with standard of care. Kardia Mobile is an FDA approved device that allows one- or six lead ECG recording for 30 seconds using the patient's smart phone. The device has a automated algorithm that interprets the ECG as either sinus rhythm, AF, or unclassified. The intervention arm will be given a KardiaMobile device, free of charge, to be synched to their smartphone at the time of enrollment. They will be instructed on proper device procedure and will use the device with the onset of potential AF-related symptoms (e.g. chest pressure, palpitations, lightheadedness, syncope, shortness of breath, or other symptoms concerning for a cardiac etiology) or when requested to do so by their healthcare provider. The device ECG recordings will be transmitted to participants physicians through MyChart who will incorporate this information into the patient's treatment as indicated. All files will be stored on a private, secure platform and any subsequent communication from the clinical team will occur via standard clinical channels (MyChart or telephone contact). Healthcare utilization will be assessed by having the participants in both groups complete a questionnaire asking how many times they used their KardiaMobile device (if randomized to this group) and how many office appointments, emergency department visits, and hospital admissions they had within that six-month period.

Arms and Interventions

| Participant Group/Arm | Intervention/Treatment |
| --- | --- |
| Experimental: Kardia Mobile Group<br>The intervention arm will be given a KardiaMobile device synched to their smartphone at the time of enrollment. They will be instructed on proper device procedure and will use the device with the onset of potential AF-related symptoms or when requested to do so by their healthcare provider. The device ECG recordings will be transmitted to participants physicians through MyChart who will incorporate this information into the patient's treatment as indicated. Healthcare utilization will be assessed by having the participants in both groups complete a questionnaire asking how many times they used their KardiaMobile device (if randomized to this group) and how many office appointments, emergency department visits, and hospital admissions they had within that six-month period. | Other: Kardia Mobile 6L Device<br>* The KardiaAL is a software analysis library intended to assess ambulatory electrocardiogram (ECG) rhythms from adult subjects. The device supports analyzing data recorded in compatible fonnats from any ambulatory ECG devices such as event recorders, or other similar devices. The library is intended to be integrated into other device software. The library is not intended for use in life supporting, or sustaining systems, or ECG monitors, or cardiac alarm, or OTC use only devices. The KardiaAI library provides the following capabilities: ECG noise filtering, heart rate measurement from ECGs, detection of noisy ECGs, and ECG rhythm analysis for detecting the presence of normal sinus rhythm, atrial fibrillation, bradycardia, and tachycardia (when prescribed or used under the care of a physician).<br>|
| No Intervention: Standard of Care Group<br>The standard of care group will follow their routine care for their atrial fibrillation. Healthcare utilization will be assessed by having the participants in both groups complete a questionnaire asking how many times they used their KardiaMobile device (if randomized to this group) and how many office appointments, emergency department visits, and hospital admissions they had within that six-month period. | |

Primary Outcome Measures

| Outcome Measure | Measure Description | Time Frame |
| --- | --- | --- |
| To compare healthcare utilization through a questionnaire asking how many office appointments, emergency department visits, and hospital admissions they had within that 6 months. | Kardia Mobile is an FDA approved device that allows one- or six lead ECG recording for 30 seconds using the patient's smart phone. The device has a automated algorithm that interprets the ECG as either sinus rhythm, AF, or unclassified. The intervention arm will be given a KardiaMobile device. They will be instructed on proper device procedure and will use the device with the onset of potential AF-related symptoms (e.g. chest pressure, palpitations, lightheadedness, syncope, shortness of breath, or other symptoms concerning for a cardiac etiology) or when requested to do so by their healthcare provider.

Secondary Outcome Measures

| Outcome Measure | Measure Description | Time Frame |
| --- | --- | --- |
| To compare participants healthcare-related satisfaction through a questionnaire that will ask the participants at baseline and at 6 months how satisfied they are or have been with their AF care. | At baseline the investigators will ask participants questions about their current satisfaction with their standard to care related to their atrial fibrillation. Then at six months, the investigators will ask participants the same questions asked at baseline to assess their satisfaction with their care over the past six months. | 6 Months |
