Summary

This study will compare the effectiveness of the use of a Patient Decision Aid (PDA) and an Encounter Decision Aid (EDA) on Shared Decision Making (SDM) and health outcomes for at-risk participants with Atrial Fibrillation (AF) at 6 study sites. We hypothesize the combination of the PDA and EDA will be more effective in promoting high-quality SDM and in adoption of and adherence to anticoagulation than either tool alone.

Detailed description

Background Information: Atrial fibrillation (AF) is the most common cardiac arrhythmia worldwide, and it continues to grow in prevalence, afflicting an estimated 3 million Americans. While treatment of AF symptoms can be resource-intensive, another source of physical, social, and economic burden is thromboembolic stroke, the major cause of morbidity and mortality for both symptomatic and asymptomatic people with AF. People with AF must decide on a stroke prevention medication (typically, Warfarin or Oral Anti-Coagulants (OACs)). Shared Decision Making (SD) is particularly useful when decisions, such as this, are value laden and complex. Models of SDM stress clear communication of the risks and benefits of all treatment options (including no treatment) to patients, who in turn need opportunities to share their treatment preferences, relevant values, and goals of care. Decision aids are tools designed to support both people with AF and clinicians in SDM by 1) providing accurate, balanced information; 2) clarifying patients' values; and 3) improving SDM skills. Two types of decision aids will be evaluated in the study: a patient-centered Patient Decision Aid (PDA) and an Encounter Decision Aid for collaborative use by the clinician and patient. The PDA is intended to help people with AF prepare for the medical visit with foundational understanding and questions. The EDA is intended to promote SDM between the clinician and person with AF. Research Design \& Methods: Through a randomized controlled trial, our study will address whether the use of a PDA, and EDA, a combination of the 2, or usual care achieves the best SDM process and health outcomes. We will assess the comparative effectiveness of those 4 approaches in terms of their ability to affect the following outcomes: 1) SDM outcomes, including decisional conflict, knowledge, and quality of patient-clinician communication; and 2) health outcomes, including adoption rates of anticoagulation therapy, adherence to anticoagulation therapy regimen, bleeding, stroke/systemic embolism, and death. Data collection will include medical record review, survey completion, and video/audio recording of the clinician encounter. Study sites: Recruitment is planned to occur from 6 sites within the US. Data Collection: Self-reported outcomes from people with AF and clinicians will be collected at the end of each clinical encounter. In addition, clinicians will complete a survey that collects data on their demographics and practice characteristics. Data from the medical record will be abstracted for all enrolled participants with AF to capture demographic, clinical, and medication prescription data.

Interventions

Type	Name	Description
OTHER	Patient Decision Aid	The Patient Decision Aid (PDA) is an interactive website designed for use by a participant without the need of their clinician present. It provides information about the atrial fibrillation diagnosis, possible treatments, the effect of this diagnosis on daily life, and how to prepare for a discussion about medications with a clinician. Participants may interact with the website by inputting their health information into the stroke risk calculator or answering questions about their values, goals, thoughts, etc. that they would like to discuss with their clinician.
OTHER	Encounter Decision Aid	The Encounter Decision Aid (EDA) is an interactive website designed for use by a participant and their clinician together. Together, the clinician and participant can go through the website together and input the participant's health information into the same stroke risk calculator also in the PDA. The EDA also provides information about the diagnosis of AF, living with this diagnosis, and possible treatments, and prompts discussion of how a participant's values affects these aspects of AF.
