Objective:
To examine the feasibility of implementing remote atrial fibrillation (AF) self-screening among older people supported by a remote central monitoring system.
Design:
Process evaluation of the Mass AF randomised clinical trial (ACTRN12621000184875) with one-to-one semistructured interviews using interview guides underpinned by the Critical Realism approach and coded using the UK Medical Research Council Guidance of Process Evaluation Framework.
Setting And Participants:
Community-dwelling people aged ≥75 years from both genders (ratio 1:1) and urban/rural (ratio 2:1) in Australia.
Interventions:
Participants were provided handheld single-lead electrocardiogram (ECG) devices and trained to self-record ECGs once daily on weekdays for at least 6 months. A remote central team notified participants and general practitioners (GPs) of AF.
Primary Feasibility Outcomes:
The strengths, weaknesses, opportunities and threats (SWOT) analysis examined enablers (ie, strengths and opportunities) and barriers (ie, weaknesses and threats).
Results:
Overall, 200 participants; 98.5% completed the 6-month programme, 96% reported being satisfied with screening and 48 were interviewed: mean age 79 years, 54% male and 71% urban. 11 GPs were interviewed: 55% female and 64% urban. Programme participants trusted the remote monitoring system that supported the screening programme and provided follow-up pathways where required. GPs saw opportunities to introduce this self-screening programme to at-risk patients and improve patients' risk profiles. Programme participants reported that after being trained to use the device, they felt empowered to do self-screening and found it convenient. GPs saw empowerment could enhance the doctor-patient relationship. Participants and GPs valued screening in diagnosing AF that would otherwise be missed in usual care, but the uncertainty of effective screening duration could be a barrier.
Conclusions:
This screening programme was feasible with the reinforcement of the underpinning enablers. Several implementation strategies were identified using SWOT analysis, including leveraging the opportunity for GPs to introduce this screening programme to at-risk patients.
