RESUMO
BACKGROUND: Cognitive impairment (CI) is common in patients with acute coronary syndrome (ACS) but is often undetected and may affect recovery and secondary prevention uptake. Nurses play a crucial role providing care for patients with ACS and promoting secondary prevention. AIM: This study aimed to explore current nursing practices and barriers regarding CI screening in patients with ACS. METHODS: Cardiac nurses were recruited from three metropolitan teaching hospitals and two professional associations in Australia and undertook a 38-question purpose-built survey. RESULTS: A total of 95 nurses participated (mean age 38±13 years; 78% [n=74] female): 69 were registered nurses, and 48% had received CI training. Only 16% of nurses in our sample reported that they regularly screen for CI, and 23% reported that they never screen; however, 59% believed screening should be part of everyday practice. Nurses mostly screened when ward policy required admission/daily cognitive screening (34%) or when they suspected cognitive problems or decline (39%). Nurses in acute settings (vs non-acute) were nine times more likely to screen when adjusting for confounders. The typically used screening instruments assessed delirium/confusion and dementia but not milder CI. Common barriers to screening included communication difficulties, patients too unstable/unwell, time constraints requiring clinical care prioritisation, and being unaware of patients' normal cognition status. CONCLUSIONS: Screening practices for CI in the context of ACS were found to be suboptimal, with only 16% of nurses in our sample reporting regularly screening. The most used methods focus on screening for delirium. Given current practice, many CI cases will be missed, especially mild CI, which will negatively affect secondary prevention efforts. Further research is required to identify appropriate methods to implement routine screening within the nursing clinical workflow and establish a suitable screening tool.

OBJECTIVE: To assess whether atrial fibrillation (AF) self-screening stations in general practice waiting rooms improve AF screening, diagnosis, and stroke risk management. DESIGN, SETTING: Intervention study (planned duration: twelve weeks) in six New South Wales general practices (two in rural locations, four in greater metropolitan Sydney), undertaken during 28 August 2020 - 5 August 2021. PARTICIPANTS: People aged 65 years or more who had not previously been diagnosed with AF, and had appointments for face-to-face GP consultations. People with valvular AF were excluded. INTERVENTION: AF self-screening station and software, integrated with practice electronic medical record programs, that identified and invited participation by eligible patients, and exported single-lead electrocardiograms and automated evaluations to patients' medical records. MAIN OUTCOME MEASURES: Screening rate; incidence of newly diagnosed AF during intervention and pre-intervention periods; prescribing of guideline-recommended anticoagulant medications. RESULTS: Across the six participating practices, 2835 of 7849 eligible patients (36.1%) had face-to-face GP appointments during the intervention period, of whom 1127 completed AF self-screening (39.8%; range by practice: 12-74%). AF was diagnosed in 49 screened patients (4.3%), 44 of whom (90%) had CHA2 DS2 -VA scores of 2 or more (high stroke risk). The incidence of newly diagnosed AF during the pre-intervention period was 11 cases per 1000 eligible patients; during the intervention period, it was 22 per 1000 eligible patients (screen-detected: 17 per 1000 eligible patients; otherwise detected: 4.6 per 1000 eligible patients). Prescribing of oral anticoagulation therapy for people newly diagnosed with AF and high stroke risk was similar during the pre-intervention (20 of 24, 83%) and intervention periods (46 of 54, 85%). CONCLUSIONS: AF self-screening in general practice waiting rooms is a feasible approach to increasing AF screening and diagnosis rates by reducing time barriers to screening by GPs. AF self-screening could reduce the number of AF-related strokes. TRIAL REGISTRATION: Australian New Zealand Clinical Trials Registry ACTRN12620000233921 (prospective).

BACKGROUND: Cognitive impairment (CI) may contribute to difficulties in understanding and implementing secondary prevention behavior change after acute coronary syndrome (ACS), but the association is poorly understood. OBJECTIVES: The aim of this study was to explore the prevalence of CI in patients 4 weeks post ACS and the association with health literacy and secondary prevention. METHODS: Patients with ACS who were free from visual deficits, auditory impairment, and dementia diagnoses were recruited and assessed 4 weeks post discharge for cognitive function (Montreal Cognitive Assessment and Hopkins Verbal Learning Test), health literacy (Newest Vital Sign), depression (Patient Health Questionnaire), physical activity (Fitbit Activity Tracker and Physical Activity Scale for the Elderly), and medication knowledge and adherence. RESULTS: Participants (n = 45) had an average age of 65 ± 11 years, 82% were male, 64% were married/partnered, and 82% had high school education or higher. Overall CI was identified in 28.9% (n = 13/45) of the patients 4 weeks after discharge, which was composed of patients detected on both the Montreal Cognitive Assessment and Hopkins Verbal Learning Test (n = 3), patients detected on Montreal Cognitive Assessment alone (n = 6), and patients detected on Hopkins Verbal Learning Test alone (n = 4). Fewer patients with CI had adequate health literacy (61.4%) than patients with normal cognition (90.3%, P = .024). Significant correlations were found between Hopkins Verbal Learning Test scores and medication knowledge (0.4, P = .008) and adherence (0.33, P = .029). CONCLUSIONS: In this exploratory study, 30% of patients with ACS demonstrated CI at 4 weeks post discharge. Two screening instruments were required to identify all cases. Cognitive impairment was significantly associated with health literacy and worth further investigation.

AIM: The aim of this study is to determine health professionals' experiences communicating with Chinese immigrants and identify potential education barriers. BACKGROUND: Health professionals caring for Chinese immigrants often encounter communication barriers, leading to uncertainty of quality of care. DESIGN: This study is a quantitative and qualitative systematic review. DATA SOURCES: MEDLINE, Scopus, CINAHL, PubMed and Google Scholar were searched, limited to 1980 to October 2020. REVIEW METHODS: Articles were included if they reported results about health professional communication with Chinese patients. Quality was appraised using Consolidated Criteria for Reporting Qualitative Research guidelines and thematic synthesis conducted. RESULTS: Of 1363 articles, seven studies were included. These described provider-patient communication in primary care, oncology and palliative settings only. Three core themes were identified: (1) family-centred health communication where family controls provider-patient information exchange; (2) mismatch of provider-patient health beliefs and knowledge on diet, nutrition, traditional medicine, place for death and disease prevention and (3) mismatch of language and resources as skilled providers proficient in specific dialects are limited; communication resources are perceived as infrequently available and content is insufficient. CONCLUSION: Studies describing health professionals' experiences communicating with Chinese immigrants are limited. Key barriers identified included cultural and language disparities and communication resources are inadequate to support health professionals' needs.

BACKGROUND: Atrial fibrillation (AF) is underdiagnosed and especially undertreated in China. We aimed to investigate the prevalence of unknown and untreated AF in community residents (≥65 years old) and to determine whether an education intervention could improve oral anticoagulant (OAC) prescription. METHODS AND FINDINGS: We performed a single-time point screening for AF with a handheld single-lead electrocardiography (ECG) in Chinese residents (≥65 years old) in 5 community health centers in Shanghai from April to September 2017. Disease education and advice on referral to specialist clinics for OAC treatment were provided to all patients with actionable AF (newly detected or undertreated known AF) at the time of screening, and education was reinforced at 1 month. Follow-up occurred at 12 months. In total, 4,531 participants were screened (response rate 94.7%, mean age 71.6 ± 6.3 years, 44% male). Overall AF prevalence was 4.0% (known AF 3.5% [n = 161], new AF 0.5% [n = 22]). The 183 patients with AF were older (p < 0.001), taller (p = 0.02), and more likely to be male (p = 0.01), and they had a higher prevalence of cardiovascular disease than those without AF (p < 0.001). In total, 85% (155/183) of patients were recommended for OAC treatment by the established guidelines (CHA2DS2-VASc ≥ 2 for men; ≥ 3 for women). OAC prescription rate for known AF was 20% (28/138), and actionable AF constituted 2.8% of all those screened. At the 12-month follow-up in 103 patients (81% complete), despite disease education and advice on specialist referral, only 17 attended specialist clinics, and 4 were prescribed OAC. Of those not attending specialist clinics, 71 chose instead to attend community health centers or secondary hospital clinics, with none prescribed OAC, and 15 had no review. Of the 17 patients with new AF and a class 1 recommendation for OAC, only 3 attended a specialist clinic, and none were prescribed OAC. Of the 28 AF patients taking OAC at baseline, OAC was no longer taken in 4. Ischemic stroke (n = 2) or death (n = 3) occurred in 5/126 (4%), with none receiving OAC. As screening was performed at a single time point, some paroxysmal AF cases may have been missed; thus, the rate of new AF may be underestimated. CONCLUSIONS: We demonstrated a noticeable gap in AF detection and treatment in community-based elderly Chinese: actionable AF constituted a high proportion of those screened. Disease education and advice on specialist referral are insufficient to close the gap. Before more frequent or intensive screening for unknown AF could be recommended in China, greater efforts must be made to increase appropriate OAC therapy in known AF to prevent AF-related stroke.

BACKGROUND: Non-adherence to medications is common in patients with atrial fibrillation (AF), increasing the risk of stroke, co-morbidities, and AF symptoms. Understanding factors influencing medication adherence is important in providing holistic care to patients with AF. This study aimed to explore medication adherence in patients with AF, and explore associations with health literacy, cognition, or AF knowledge. METHODS: A single-centre pilot study, using survey questionnaires and open questions. Patients with a primary cardiac diagnosis, with AF as primary or secondary diagnosis, were eligible for recruitment. During hospitalisation, adherence to cardiac medications was assessed using the Basel Assessment of Adherence to Immunosuppressive Medication Scale (BAASIS). Health literacy, cognition, and AF knowledge were assessed through validated questionnaires. Facilitators and barriers for medication adherence were obtained through open-ended question and coded using a content analysis approach. RESULTS: Fifty-four (54) patients were recruited (61% male, mean age 71±11). Twenty-two (22) participants (41%) were classified as non-adherent using the BAASIS; with a corresponding self-reported adherence of 87.7% in non-adherent participants compared to 97.8% in adherent participants. No associations were identified between medication adherence and cognition, health literacy, or AF knowledge. Facilitators for adherence included external assistance, routines, and medication knowledge, and these were reported by both adherent and non-adherent participants. Non-adherent participants reported more barriers including medication concerns, forgetfulness, and lifestyle factors. CONCLUSIONS: Large numbers of AF patients are likely to be non-adherent to medications. Medication adherence is influenced by multiple factors, individual to each patient. Diverse strategies are required to ensure adherence to cardiac medications.

BACKGROUND: The precise age distribution and calculated stroke risk of screen-detected atrial fibrillation (AF) is not known. Therefore, it is not possible to determine the number needed to screen (NNS) to identify one treatable new AF case (NNS-Rx) (i.e., Class-1 oral anticoagulation [OAC] treatment recommendation) in each age stratum. If the NNS-Rx is known for each age stratum, precise cost-effectiveness and sensitivity simulations can be performed based on the age distribution of the population/region to be screened. Such calculations are required by national authorities and organisations responsible for health system budgets to determine the best age cutoffs for screening programs and decide whether programs of screening should be funded. Therefore, we aimed to determine the exact yield and calculated stroke-risk profile of screen-detected AF and NNS-Rx in 5-year age strata. METHODS AND FINDINGS: A systematic review of Medline, Pubmed, and Embase was performed (January 2007 to February 2018), and AF-SCREEN international collaboration members were contacted to identify additional studies. Twenty-four eligible studies were identified that performed a single time point screen for AF in a general ambulant population, including people ≥65 years. Authors from eligible studies were invited to collaborate and share patient-level data. Statistical analysis was performed using random effects logistic regression for AF detection rate, and Poisson regression modelling for CHA2DS2-VASc scores. Nineteen studies (14 countries from a mix of low- to middle- and high-income countries) collaborated, with 141,220 participants screened and 1,539 new AF cases. Pooled yield of screening was greater in males across all age strata. The age/sex-adjusted detection rate for screen-detected AF in ≥65-year-olds was 1.44% (95% CI, 1.13%-1.82%) and 0.41% (95% CI, 0.31%-0.53%) for <65-year-olds. New AF detection rate increased progressively with age from 0.34% (<60 years) to 2.73% (≥85 years). Neither the choice of screening methodology or device, the geographical region, nor the screening setting influenced the detection rate of AF. Mean CHA2DS2-VASc scores (n = 1,369) increased with age from 1.1 (<60 years) to 3.9 (≥85 years); 72% of ≥65 years had ≥1 additional stroke risk factor other than age/sex. All new AF ≥75 years and 66% between 65 and 74 years had a Class-1 OAC recommendation. The NNS-Rx is 83 for ≥65 years, 926 for 60-64 years; and 1,089 for <60 years. The main limitation of this study is there are insufficient data on sociodemographic variables of the populations and possible ascertainment biases to explain the variance in the samples. CONCLUSIONS: People with screen-detected AF are at elevated calculated stroke risk: above age 65, the majority have a Class-1 OAC recommendation for stroke prevention, and >70% have ≥1 additional stroke risk factor other than age/sex. Our data, based on the largest number of screen-detected AF collected to date, show the precise relationship between yield and estimated stroke risk profile with age, and strong dependence for NNS-RX on the age distribution of the population to be screened: essential information for precise cost-effectiveness calculations.

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. RESULTS: GPs/nurses liked the eHealth tools, although technical problems sometimes disrupted screening. Time was the main barrier to screening for GPs/nurses, so systems need to be very efficient. Practices with leadership from a senior GP 'screening champion' had broader uptake, especially from the nursing team. Providing regular feedback on screening data was beneficial for quality improvement and motivation. Clear protocols for follow-up of abnormal results were required for successful nurse-led screening in a hierarchical system. Participation in the program had broader benefits of improving AF knowledge and raising the profile of cardiovascular health in the practice. Screening for a shorter, more intense period (eg during influenza vaccination) worked well for practices where sufficient staff time was allocated. CONCLUSIONS: Introducing an AF screening program is likely to be successful in contexts where there is a senior GP 'screening champion', a clear protocol exists for abnormal results, and there is regular data reporting to staff. These contexts link to mechanisms around motivation, leadership, empowerment of nurses, and efficient screening systems. The contexts and mechanisms contribute to the longer-term outcomes of increasing the proportion of people screened and treated for AF, which is recommended by guidelines as a key strategy for the prevention of AF-related stroke.

Approximately 10% of ischemic strokes are associated with atrial fibrillation (AF) first diagnosed at the time of stroke. Detecting asymptomatic AF would provide an opportunity to prevent these strokes by instituting appropriate anticoagulation. The AF-SCREEN international collaboration was formed in September 2015 to promote discussion and research about AF screening as a strategy to reduce stroke and death and to provide advocacy for implementation of country-specific AF screening programs. During 2016, 60 expert members of AF-SCREEN, including physicians, nurses, allied health professionals, health economists, and patient advocates, were invited to prepare sections of a draft document. In August 2016, 51 members met in Rome to discuss the draft document and consider the key points arising from it using a Delphi process. These key points emphasize that screen-detected AF found at a single timepoint or by intermittent ECG recordings over 2 weeks is not a benign condition and, with additional stroke factors, carries sufficient risk of stroke to justify consideration of anticoagulation. With regard to the methods of mass screening, handheld ECG devices have the advantage of providing a verifiable ECG trace that guidelines require for AF diagnosis and would therefore be preferred as screening tools. Certain patient groups, such as those with recent embolic stroke of uncertain source (ESUS), require more intensive monitoring for AF. Settings for screening include various venues in both the community and the clinic, but they must be linked to a pathway for appropriate diagnosis and management for screening to be effective. It is recognized that health resources vary widely between countries and health systems, so the setting for AF screening should be both country- and health system-specific. Based on current knowledge, this white paper provides a strong case for AF screening now while recognizing that large randomized outcomes studies would be helpful to strengthen the evidence base.

BACKGROUND: Chinese immigrants are at an increased risk for cardiovascular diseases (CVDs) compared with Chinese nationals partly because of lifestyle changes and knowledge deficits. Translated patient resources are available on the Internet and are often provided by health professionals; however, the quality and cultural sensitivity of these resources have not been reported. OBJECTIVE: The aim of this study was to assess the availability, quality, and cultural sensitivity of Chinese-language information available from national "Heart Foundations" (cardiac research bodies, nongovernmental organisations) of the 5 most popular destinations of Chinese immigration. METHODS: This study is a descriptive research in which national "Heart Foundation" websites were systematically searched for Chinese-language CVD patient education resources. Quality (content, identification, structure) was assessed using the Ensuring Quality Information for Patients instrument. Cultural sensitivity was evaluated using the Cultural Sensitivity Assessment Tool. RESULTS: From 107 identified resources, 33 were CVD specific: coronary heart disease (n = 20), arrhythmias (n = 7), and heart failure (n = 6). Quality of resources was adequate (mean Ensuring Quality Information for Patients score, 69%), but scores varied significantly (min, 60%; max, 85%). Although all resources were classified as culturally sensitive (Cultural Sensitivity Assessment Tool score ≥ 2.5), 2 resources scored low (≤2.5) for visual impact, and across all resources, written and visual domains were assessed as least culturally sensitive. Most resources lacked culturally specific references. CONCLUSIONS: Chinese-language CVD resources were inconsistent in the supply of key information. Quality and level of cultural sensitivity were adequate, but most resources lacked culturally specific references. Comprehensive, high-quality CVD resources powered by Editorial Manager and ProduXion Manager from Aries Systems Corporation tailored for Chinese immigrants are urgently needed for healthcare providers to support CVD education and care of patients belonging to this population.

BACKGROUND: Globally, attendance at cardiac rehabilitation (CR) is between 15 and 30%. Alternative models of individualised care are recommended to promote participation in CR, however there has been no prospective testing of different durations of such models. We aimed to replicate the previously proven Choice of Health Options In prevention of Cardiovascular Events (CHOICE) intervention, and to determine if an extended version (CHOICEplus) would confer additional benefits. METHODS: Acute coronary syndrome (ACS) survivors not accessing centre-based CR (n=203) were randomised to CHOICE for 3 months (n=100) or CHOICEplus for 24 months (n=103) at four urban hospitals. The program comprised telephone-based tailored risk-factor reduction. RESULTS: CHOICE and CHOICEplus were equivalent demographically and in risk profile at baseline. At 24 months, lipid profiles improved significantly and fewer patients had ≥3 risk factors above target compared to baseline in both groups. There were no significant differences between groups. CONCLUSIONS: The 24-month CHOICEplus program did not confer additional benefit above the brief 3-month CHOICE intervention. However, participation in either CHOICE and CHOICEplus significantly improved cardiovascular risk profile in ACS survivors. Importantly, the study was feasible, and the intervention translated readily across four hospitals. Overall, this study adds to the existing evidence for brief individualised approaches to CR.

Atrial fibrillation (AF) is the most common cardiac arrhythmia, with a lifetime risk of one in four of developing AF over the age of 40 years. Around 40% of patients are asymptomatic, which is of concern as AF is a major risk factor for stroke. Early detection and appropriate management reduces stroke risk by two-thirds. Atrial fibrillation screening is now recommended in international guidelines, but there are some common arguments against screening. Overall, to be of value any screening program must fulfil the World Health Organization (WHO) Wilson and Jungner criteria for screening programs. In this paper we address the common arguments, and determine if AF screening fulfils the WHO criteria.

AIMS AND OBJECTIVES: To investigate whether using the 'think aloud' technique during standard quality of life surveys provides useful additional information about patients' experiences of living with atrial fibrillation (AF) and health related quality of life (HRQoL). BACKGROUND: Atrial fibrillation is the most common cardiac arrhythmia and has serious health consequences, particularly ischaemic stroke, high rates of morbidity and mortality and poor HRQoL. Standard quality-of-life questionnaires are often used but may not provide sufficient detail of patients' experiences living with AF. DESIGN: A qualitative interpretative study based on semi-structured interviews. METHODS: Patients with AF (n=12) were recruited from the Choice of Health Options in Prevention of Cardiovascular Events-in Atrial Fibrillation (CHOICE-AF), a risk factor management program. Participants were interviewed using a 'think aloud' technique with questions guided by the AF Effects on Quality Of Life Questionnaire (AFEQT) and the Short Form-12 (SF-12). Interviews were audio-recorded, transcribed and analysed thematically. RESULTS: Participants had a median age of 71 years (interquartile range 52 to 77 years), and included four women and eight men. Four themes were identified related to experiences of living with AF and HRQoL including: (1) the adverse impact of atrial fibrillation symptoms, treatments, and related knowledge; (2) loss of function or independence; (3) the influence of age; and (4) approach to life. CONCLUSIONS: Atrial fibrillation, especially in older adults, creates an additional layer of requirements for self-management onto existing self-care needs. Even for patients with relatively high HRQoL, the 'think aloud' technique together with standard HRQoL questionnaires can help identify additional issues that can be addressed by health professionals to improve the HRQoL of these patients.

BACKGROUND: Atrial fibrillation (AF) is often asymptomatic and substantially increases stroke risk. A single-lead iPhone electrocardiograph (iECG) with a validated AF algorithm could make systematic AF screening feasible in general practice. METHODS: A qualitative screening pilot study was conducted in three practices. Receptionists and practice nurses screened patients aged ≥65 years using an iECG (transmitted to a secure website) and general practitioner (GP) review was then provided during the patient's consultation. Fourteen semi-structured interviews with GPs, nurses, receptionists and patients were audio-recorded, transcribed and analysed thematically. RESULTS: Eighty-eight patients (51% male; mean age 74.8 ± 8.8 years) were screened: 17 patients (19%) were in AF (all previously diagnosed). The iECG was well accepted by GPs, nurses and patients. Receptionists were reluctant, whereas nurses were confident in using the device, explaining and providing screening. DISCUSSION: AF screening in general practice is feasible. A promising model is likely to be one delivered by a practice nurse, but depends on relevant contextual factors for each practice.

Hypertension and atrial fibrillation are closely related. However, hypertension is already prevalent in young adults, but atrial fibrillation usually occurs in the elderly. In the present analysis, we investigated incident atrial fibrillation in relation to new-onset hypertension in an elderly Chinese population. Our study participants were elderly (≥65 years) hypertensive residents, recruited from community health centers in the urban Shanghai (n = 4161). Previous and new-onset hypertension were defined as the use of antihypertensive medication or elevated systolic/diastolic blood pressure (≥140/90 mmHg), respectively, at entry and during follow-up on ≥ 2 consecutive clinic visits. Atrial fibrillation was detected by a 30-s single-lead electrocardiography (ECG, AliveCor® Heart Monitor) and further evaluated with a regular 12-lead ECG. During a median of 2.1 years follow-up, the incidence rate of atrial fibrillation was 7.60 per 1000 person-years in all study participants; it was significantly higher in patients with new-onset hypertension (n = 368) than those with previous hypertension (n = 3793, 15.76 vs. 6.77 per 1000 person-years, P = 0.02). After adjustment for confounding factors, the hazard ratio for the incidence of atrial fibrillation was 2.21 (95% confidence interval 1.15-4.23, P = 0.02) in patients with new-onset hypertension versus those with previous hypertension. The association was even stronger in those aged ≥ 75 years (hazard ratio 2.70, 95% confidence interval 1.11-6.56, P = 0.03). In patients with previous hypertension, curvilinear association (P for non-linear trend = 0.04) was observed between duration of hypertension and the risk of incident atrial fibrillation, with a higher risk in short- and long-term than mid-term duration of hypertension. Our study showed a significant association between new-onset hypertension and the incidence of atrial fibrillation in elderly Chinese. In an elderly Chinese population with previous and new-onset hypertension, we found that the new-onset hypertension during follow-up, compared with previous hypertension, was associated with a significantly higher risk of incident atrial fibrillation. In patients with previous hypertension, curvilinear association was observed between duration of hypertension and the risk of incident atrial fibrillation, with a higher risk in short- and long-term than mid-term duration of hypertension.

Background: Current Australian and European guidelines recommend opportunistic screening for atrial fibrillation (AF) among patients ≥65 years, but general practitioners (GPs) report time constraints as a major barrier to achieving this. Patient self-screening stations in GP waiting rooms may increase screening rates and case detection of AF, but the acceptability of patient self-screening from the practice staff perspective, and the usability by patients, is unknown. Objective: To determine staff perspectives on AF self-screening stations and factors impacting acceptability, usability by patients, and sustainability. Methods: We performed semi-structured interviews with 20 general practice staff and observations of 22 patients while they were undertaking self-screening. Interviews were coded and data analyzed using an iterative thematic analysis approach. Results: GPs indicated high levels of acceptance of self-screening, and reported little impact on their workflow. Reception staff recognized the importance of screening for AF, but reported significant impacts on their workflow because some patients were unable to perform screening without assistance. Patient observations corroborated these findings and suggested some potential ways to improve usability. Conclusion: AF self-screening in GP waiting rooms may be a viable method to increase opportunistic screening by GPs, but the impacts on reception workflow need to be mitigated for the method to be upscaled for more widespread screening. Furthermore, more age-appropriate station design may increase patient usability and thereby also reduce impact on reception workflow.
