Anticoagulation Optimization Through a Specialized Center for Atrial Fibrillation

Area of Science:

• Cardiology
• Health Informatics
• Preventive Medicine

Background:

• Atrial fibrillation is a common condition and a major risk factor for ischemic stroke.
• Anticoagulation therapy is effective in reducing stroke risk but is underprescribed in many patients.
• Identifying eligible patients who are not on anticoagulation is crucial for stroke prevention.

Purpose of the Study:

• To assess the effectiveness of a health record database query in identifying patients with atrial fibrillation who are not on anticoagulation therapy.
• To determine the reasons for deferring anticoagulation in this patient population.
• To evaluate the impact of this identification process on specialist referrals.

Main Methods:

• A health record database query was used to identify patients with atrial fibrillation lacking active anticoagulation prescriptions.
• Primary care providers reviewed patient charts to document reasons for anticoagulation deferral.
• A subset of identified patients were analyzed for appropriate reasons for deferral.

Main Results:

• The database query successfully identified patients with atrial fibrillation not receiving anticoagulation.
• A significant subset of these patients were found to have no appropriate clinical reason for deferring anticoagulation.
• The initiative led to an increased number of referrals to a specialized atrial fibrillation care center.

Conclusions:

• Health record queries can effectively identify atrial fibrillation patients who may benefit from anticoagulation.
• Inappropriate deferral of anticoagulation is a barrier to stroke prevention in atrial fibrillation.
• This systematic approach can improve patient management and increase access to specialized care.
