Clinical Trial Summary

Atrial fibrillation (AF) is a highly prevalent, morbid condition. Anticoagulation to prevent thromboembolic strokes is a foremost priority in AF but adherence is challenging for patients and lapses in anticoagulation are common. Chronic disease self-management (CDSM) is a recognized program to enhance self-efficacy and improve adherence, quality of life, and patient-centered health outcomes. Rural patients with AF experience increased vulnerability to adverse outcomes due to geographic and social isolation, poor health care access, and limited health literacy. This study uses an innovative, scalable CDSM intervention to improve anticoagulation adherence in rural patients with AF.


Clinical Trial Description

This is a randomized clinical trial to evaluate the effect of a smartphone-based intervention called an embodied conversational agent (ECA) on health outcomes in people with atrial fibrillation. The study will enroll 264 patients who reside in rural, Western Pennsylvania who have atrial fibrillation. Participants will be randomized to the intervention or control. Intervention participants will receive a smartphone with a relational agent, which simulates conversation and provides coaching, guidance, and assistance with chronic disease self-management. In addition participants will receive an AliveCor Kardia for heart rate and rhythm monitoring, an FDA-approved, widely used instrument that pairs with the relational agent. Control participants will receive a smartphone with as well, which will have the health application WebMD. The intervention will last 4 months and participants will have visits at baseline, 4, 8 and 12 months. The study will evaluate the improvement in adherence to anticoagulation, quality of life, and health care utilization resulting from the intervention. ;
