Shared Decision Making to Address Racial Disparities in Oral Anticoagulation in NVAF

March 18, 2026 updated by: Duke University

Shared Decision Making to Address Racial Disparities in Oral Anticoagulation Use in Patients With Non-valvular Atrial Fibrillation

The study is a pilot analysis using a decision on the risk and benefits of oral anticoagulation for stroke reduction for patients with non-valvular atrial fibrillation. This study is a feasibility and acceptability analysis but will also measure preliminary effectiveness measures.

The investigator hypothesizes that a patient decision support tool will increase decision quality and secondarily increase the use of oral anticoagulation in Black patients with non-valvular atrial fibrillation.

Arms and Interventions

Participant Group / Arm
Intervention / Treatment
Experimental: Patient Decision Support Tool
Patient decision support tool to be used in conjunction with physician counseling to discuss the risk and benefits of systemic oral anticoagulation.
Other: Patient Decision Support Tool
Patient decision support tool is a web based educational material that informs a patient on the risk and benefits of oral anticoagulation. In addition, such a tool aims to assess patient values and preferences in the decision making process for oral anticoagulation for stroke reduction.
No Intervention: Usual Healthcare Counseling
Traditional physician counseling regarding the risk and benefits of systemic oral anticoagulation
