IntroductionScreening for atrial fibrillation (AF) in people ≥65 years is now recommended by guidelines and expert consensus. While AF is often asymptomatic, it is the most common heart arrhythmia and is associated with increased risk of stroke. Early identification and treatment with oral anticoagulants can substantially reduce stroke risk. The general practice setting is ideal for opportunistic screening and provides a natural pathway for treatment for those identified.This study aims to investigate the feasibility of implementing screening for AF in rural general practice using novel electronic tools. It will assess whether screening will fit within an existing workflow to quickly and accurately identify AF, and will potentially inform a generalisable, scalable approach.Methods and analysisScreening with a smartphone ECG will be conducted by general practitioners and practice nurses in rural general practices in New South Wales, Australia for 3–4 months during 2018–2019. Up to 10...

Background: Screening for atrial fibrillation (AF) in people aged ≥65 years is recommended by international guidelines. The Atrial Fibrillation Screen, Management And guideline-Recommended Therapy (AF-SMART) studies of opportunistic AF screening in 16 metropolitan and rural general practices were conducted from November 2016-June 2019. These studies trialled custom-designed eHealth tools to support all stages of AF screening in general practice. Methods: A realist evaluation of the AF-SMART studies, which aimed to explain the circumstances in which the program worked (or not) to increase the proportion of people screened for AF. The initial program theory was based on our previous research, policy documents and screening studies. To test this, we conducted 45 semi-structured interviews with general practitioners (GPs), nurses and practice managers across all participating practices, and collected observational and quantitative screening data. These data were analysed and interpreted to refine the program theory.
Regional implementation of atrial fibrillation screening: benefits and pitfalls
European Heart Journal - Digital Health
Aims Despite general awareness that screening for atrial fibrillation (AF) could reduce health hazards, large-scale implementation is lagging behind technological developments. As the successful implementation of a screening programme remains challenging, this study aims to identify facilitating and inhibiting factors from healthcare providers’ perspectives. Methods and results A mixed-methods approach was used to gather data among practice nurses in primary care in the southern region of the Netherlands to evaluate the implementation of an ongoing single-lead electrocardiogram (ECG)-based AF screening programme. Potential facilitating and inhibiting factors were evaluated using online questionnaires (N = 74/75%) and 14 (of 24) semi-structured in-depth interviews (58.3%). All analyses were performed using SPSS 26.0. In total, 16 682 screenings were performed on an eligible population of 64 000, and 100 new AF cases were detected. Facilitating factors included ‘receiving clear instru...
Screening for atrial fibrillation and other arrhythmias in primary care
BMC Family Practice, 2020
Background Atrial fibrillation (AF) and other arrhythmias are prevalent and often encountered by general practitioners (GPs). In response to the growing prevalence and to assist practitioners in the diagnosis and management of AF, the Cardiac Society of Australia & New Zealand and Heart Foundation of Australia published the first Australian AF Guidelines in 2018. We aimed to examine (a) the proportion of GPs who performed any form of AF screening and identify the methods they applied, (b) GPs’ awareness of the AF Guidelines and approaches to arrhythmia screening, (c) the roles of conventional 12-lead ECG and mobile health devices, and (d) GPs’ confidence in ECG interpretation and need for training. Methods A cross-sectional online survey titled “GPs Screen their patients for Atrial Fibrillation and othEr aRrhythmia (GPSAFER)” was conducted from October 2018 to March 2019. The participants were recruited via various GP networks across Australia. Ethics approval was granted by The Uni...

Background: Atrial fibrillation (AF) is associated with a high risk of stroke and may often be asymptomatic. AF is commonly undiagnosed until patients present with sequelae, such as heart failure and stroke. Stroke secondary to AF is highly preventable with the use of appropriate thromboprophylaxis. Therefore, early identification and appropriate evidence-based management of AF could lead to subsequent stroke prevention. This study aims to determine the feasibility and impact of a community pharmacy-based screening programme focused on identifying undiagnosed AF in people aged 65 years and older.

The Integrated Management Program Advancing Community Treatment of Atrial Fibrillation (IMPACT-AF) is an investigator designed, prospective, randomized, un-blinded, cluster design clinical trial, conducted in the primary care setting of Nova Scotia, Canada. Its aim is to evaluate whether an electronic Clinical Decision Support System (CDSS) designed to assist both practitioners and patients with evidence-based management strategies for Atrial Fibrillation (AF) can improve process of care and outcomes in a cost-efficient manner as compared to usual AF care. At least 200 primary care providers are being recruited and randomized at the level of the practice to control (usual care) or intervention (eligible to access to CDSS) cohorts. Over 1,000 patients of participating providers with confirmed AF will be managed per their provider's respective assignment. The targeted primary clinical outcome is a reduction in the composite of unplanned cardiovascular (CV) or major bleeding hospit...
Experiences with screening for atrial fibrillation: a qualitative study in general practice
BJGP Open, 2021
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, auto...

Background In Thailand, almost one-quarter of strokes are related to atrial fibrillation (AF), and many could be prevented if AF were diagnosed and treated prior to the stroke. Therefore, we tested a novel strategy to screen large numbers of community residents using village health volunteers and primary care nurses. Methods Local primary care nurses and village health volunteers in Phetchaburi and Lopburi provinces, Thailand were trained to perform AF screening using a blood pressure device with AF algorithm (Microlife A200 AFib). 10% of residents aged ≥ 65 years were randomly selected for screening during home-visits. Participants with possible AF were given follow-up appointments for further testing, including 12-lead ECG and echocardiogram. Results Over two-months, 9.7% (13,864/143,478) of the target population were screened: mean age 73.2 ± 6.4 years, 32.4% male. The estimated AF prevalence (detected by Microlife A200 AFib) was 2.8% (95% CI, 2.6–3.1%) for age ≥ 65 years (i.e. 3...
Process Evaluation for Technology Enabled Atrial Fibrillation Screening after a Stroke in Scotland
2020
Diagnosis of Atrial Fibrillation (AF) after stroke is a national priority. AF-related strokes typically cost twice as much to manage as non-AF related strokes (Miller et al, 2005). If diagnosed with AF, further stroke can be reduced by 60% by taking medications such as anticoagulants. Because AF can be paroxysmal- that is the heart can go in and out of AF- it is not always detected during hospitalisation for stroke. If there is a reasonable suspicion that stroke may have resulted from undetected AF, guidelines recommend screening with a Holter monitor - an ambulatory electrocardiogram (ECG) applied in a hospital clinic for 72 hours. A ‘Test of Change’ within one local hospital in Scotland (NHS Lanarkshire) was conducted during 2019 where a new managed service involving devices (applied to n=64 patients) were considered for AF screening that would allow for up to 14 days of continuous monitoring in the home setting. This new technology enabled service also included reporting conducte...
