Atrial fibrillation: a comparison of methods to identify cases in general practice

Area of Science:

• Cardiology
• Primary Care Medicine
• Preventive Cardiology

Background:

• Atrial fibrillation (AF) is a significant, treatable risk factor for stroke.
• Effective community-based screening methods are needed to identify undiagnosed AF cases.
• Early detection allows for timely initiation of antithrombotic therapy to reduce stroke risk.

Purpose of the Study:

• To evaluate the efficiency of practice-based screening strategies for atrial fibrillation.
• To assess the impact of different screening methods on time and financial costs.
• To determine the optimal approach for detecting undiagnosed atrial fibrillation in primary care settings.

Main Methods:

• Utilized nurse-led pulse palpation as an initial screening tool.
• Employed 12-lead and bipolar electrocardiographs (ECGs) for diagnostic confirmation.
• Compared various combinations of pulse palpation and ECG interpretation by practice nurses.

Main Results:

• Nurse-led pulse palpation is an effective first step in screening for atrial fibrillation.
• 12-lead ECGs are recommended for patients with a pulse suggestive of AF.
• Trained practice nurses can effectively interpret ECG findings for AF detection.

Conclusions:

• A combined strategy of nurse pulse palpation followed by ECG confirmation offers an efficient method for practice-based AF screening.
• This approach can increase the identification of previously undiagnosed atrial fibrillation cases.
• Optimized screening protocols facilitate wider access to antithrombotic treatment and stroke prevention.
