Clinical Trial Summary

This will be a prospective multi-center, randomized, controlled trial of 150 patients conducted to assess the impact of individual use of the Apple Watch compared to the Withings Move on patient-reported and clinical outcomes at 6 months and up to 1 year.

Description:

This is a a randomized, controlled trial to determine the impact of the Apple Watch Series 6 compared to the Withings Move on both patient-reported outcomes and clinical utilization over 6 months and up to 1 year. Our research method will employ a patient-centered health data sharing platform (called Hugo) for real-world surveillance of outcomes in 150 total patients after they receive elective direct current cardioversion (DCCV) or catheter ablation for treatment of atrial fibrillation or atrial flutter. Patients will be enrolled at each of 3 clinical sites: Yale-New Haven Hospital, the Mayo Clinic, and Duke Health. Half of the patients will be randomized to receive the Apple Watch Series 6, while half will receive a control device (Withings Move). Patients will then be queried about specific symptoms related to atrial fibrillation and medication adherence monthly. This project will provide novel and needed post-market data about the Apple Watch Series 6 ECG and irregular rhythm detection notification features and, on a larger scale, help delineate the impact of an innovative digital health technology on real-world patient outcomes.

Specific Aim 1: To assess the impact of using the Apple Watch ECG and irregular rhythm notification features on patient-reported outcomes and clinical utilization after patients receive cardioversion or catheter ablation for atrial fibrillation or atrial flutter.

Specific Aim 2: To determine the accuracy of the Apple Watch ECG compared to physician interpretation of 12-lead ECGs obtained in routine clinical care.

Reported on a scale from 0 to 100 with a higher score indicating a better outcome	6 months
Secondary	Proportion of participants with acute care use at 6 months	Acute care use will be compared between the two groups at 6 months. Acute care is defined as an emergency department visits, observation stays, and all hospitalizations over the 6 month period.	6 months
Secondary	Proportion of participants with acute care use at 12 months	Acute care use will be compared between the two groups at 12 months. Acute care is defined as an emergency department visits, observation stays, and all hospitalizations over the 12 month period.	12 months
Secondary	Proportion of participants with outpatient care use at 6 months	Outpatient care use will be compared between the two groups at 6 months. Outpatient care is defined as outpatient primary care visits, outpatient cardiology or cardiac electrophysiology visits, and scheduled telephone encounters.	6 months
Secondary	Proportion of participants with outpatient care use at 12 months	Outpatient care use will be compared between the two groups at 12 months. Outpatient care is defined as outpatient primary care visits, outpatient cardiology or cardiac electrophysiology visits, and scheduled telephone encounters.	12 months
