Experiences with screening for atrial fibrillation: a qualitative study in general practice

Abstract

Background: Guidelines recommend screening for atrial fibrillation (AF). Currently, screening is not considered standard care among GPs. Aim: To explore the experiences of primary care workers with different methods of screening for AF and with implementation in daily practice. Design & setting: A qualitative study using semi-structured interviews with GPs, nurses, and healthcare assistants (HCAs) who were experienced with implementing different methods of screening. Method: Two independent researchers audio-recorded and analysed interviews using a thematic approach. They asked participants about their experiences with the different methods used for screening AF and which obstacles they faced when implementing screening in daily practice. Results: In total 15 GPs, nurse practitioners, and HCAs from seven different practices were interviewed. The GP's office is suited for screening for AF, which ideally should be integrated with standard care. Participants considered pulse palpation, automated sphygmomanometer with AF detection, and single-lead electrocardiography (ECG) as practical tests. Participants trusted pulse palpation over the algorithm of the devices. The follow-up of a positive test with a time-consuming 12-lead ECG hindered integration of screening. The single-lead ECG device reduced the need for immediate follow-up because it can record a rhythm strip. The extra workload of screening and lack of financial coverage form obstacles for implementation. Conclusion: Pulse palpation, automated blood pressure measure monitors with AF detection, and single-lead ECGs might facilitate screening in a general practice setting. When implementing screening, focus should be on how to avoid disruption of consultation hours by unplanned 12- lead ECGs.
