Atrial fibrillation care in rural communities: a mixed methods study of physician and patient perspectives

The Landscape of Health Technology for Equity Deserving Groups in Rural Communities: A Systematic Review

BACKGROUND

Equity-deserving groups face well-known health disparities that are exacerbated by rural residence. Health technologies have shown promise in reducing disparities among these groups, but there has been no comprehensive evidence synthesis of outcomes.

PURPOSE

The purpose of this systematic review was to examine the patient, healthcare, and economic outcomes of health technology applications with rural living equity-deserving groups.

RESEARCH DESIGN

The databases searched included Medline and Embase. Articles were assessed for bias using the McGill mixed methods appraisal tool.

ANALYSIS

Data were synthesized narratively using a convergent integrated approach for qualitative and quantitative findings.

RESULTS

This evidence synthesis includes papers (n = 21) that reported on health technologies targeting rural equity-deserving groups. Overall, patient outcomes - knowledge, self-efficacy, weight loss, and clinical indicators - improved. Healthcare access improved with greater convenience, flexibility, time and travel savings, though travel was still occasionally necessary. All studies reported satisfaction with health technologies. Technology challenges reported related to connectivity and infrastructure issues influencing appointment quality and modality options. While some studies reported additional costs, overall, studies indicated cost savings for patients.

CONCLUSIONS

There is a paucity of research on health technologies targeting rural equity-deserving groups, and the available research has primarily focused on women. While current evidence was primarily of high quality, research is needed inclusive of equity-deserving groups and interventions co-designed with users that integrate culturally sensitive approaches.

Procedural Complications and Inpatient Outcomes of Leadless Pacemaker Implantations in Rural Versus Urban Hospitals in the United States

BACKGROUND

Disparities in invasive cardiovascular care and outcomes in rural and urban hospitals across the United States have been reported. However, studies investigating disparities regarding leadless pacemaker outcomes and complications based on hospital location are lacking.

OBJECTIVE

To evaluate differences in outcomes and complications related to leadless pacemaker implantations among rural and urban hospitals.

METHODS

The National Inpatient Sample was used to identify patients who underwent leadless pacemaker implantations in the United States from 2016 to 2020. Study endpoints assessed included procedural complications and inpatient outcomes of leadless pacemaker implantations among rural and urban hospitals.

RESULTS

From 2016 to 2020, there were a total of 28 340 and 665 leadless pacemaker implantations in urban and rural hospitals, respectively. Baseline characteristics were similar among both groups, with notable exceptions of higher rates of coagulopathies (13.2% vs. 6.8%, p < 0.001) and peripheral vascular disorders (10.4% vs. 4.5%, p < 0.001) among urban patients. After multivariable adjustment for confounding variables, leadless pacemaker placements occurring in rural hospitals had lower odds of major complications (aOR 0.59, 95% CI 0.41-0.86), but increased odds of inpatient mortality (aOR 1.70, 95% CI 1.21-2.40). Overall, rural leadless pacemaker recipients experienced lower rates of discharge to home, as well as lower costs and length of stay.

CONCLUSIONS

A majority of leadless pacemaker implantations occurred in urban hospitals in the United States. Important differences in outcomes were described based on urban and rural hospital location. Further investigation and policy changes are encouraged to promote improved cardiovascular care and outcomes in rural residents.

Regional Disparities in Atrial Fibrillation Management: An IMPACT-AF Substudy

Background

In rural regions, atrial fibrillation (AF) management is performed predominately by local primary care professionals (PCPs). Prior work has suggested that a disparity in outcomes in AF occurs for those patients living in a rural, vs urban, location.

Methods

This post hoc analysis of the cluster randomized trial Integrated Management Program Advancing Community Treatment of Atrial Fibrillation (IMPACT-AF) compared a clinical decision support system to standard of care. Patients were classified as living in a rural (population < 10,000) or urban location. The outcomes were as follows: AF-related emergency department (ED) visits, unplanned cardiovascular (CV) hospitalizations, AF-related referrals and guideline adherence for AF treatment.

Results

A total of 1133 patients were enrolled from 2016 to 2018; 54.1% (n = 613) were classified as living in a rural location. No differences were present in age (mean, 72 ± 9.63 vs 72.5 ± 10.42 years) or Congestive Heart Failure, Hypertension, Age, Diabetes, Stroke/Transient Ischemic Attack (CHADS2) score (mean, 2.1 ± 1.36 vs 2.16 ± 1.34). Referral rates to general internists were higher in the rural population (13.4% vs 3.9%, P < 0.001), whereas the rate of cardiology referrals was higher in the urban population (10% vs 15%, P = 0.0098). At 12 months, no difference in the composite outcome of AF-related ED visits and CV hospitalizations was seen. Fewer recurrent AF-related ED visits and CV hospitalizations occurred in the urban group (incidence rate ratio [IRR], 0.65 [95% confidence interval (0.44, 0.95), P = 0.0262). The incidence of guideline adherence was similar between the rural (IRR, 3.7 ± 1.2) and urban (IRR, 3.6 ± 1.2; P = 0.11) groups.

Conclusions

AF patients living in rural locations had higher rates of recurrent AF-related ED visits and unplanned CV hospitalizations. Further research to optimize AF-related outcomes is needed to ensure equitable delivery of care to all Canadians, irrespective of geography.

Assessing a Virtual Education Intervention for Patients With Atrial Fibrillation: A Qualitative Study of Patient Perceptions

BACKGROUND

Authors of studies of patients with atrial fibrillation (AF) have identified several knowledge gaps and misconceptions regarding the condition and its management. The COVID-19 pandemic heightened isolation of patients and underscored the need for education and knowledge building in order for patients to effectively manage AF during times of increased health risk.

OBJECTIVE

The aim of this study was to assess, using a qualitative approach, the experiences and perceived benefits of patients with AF regarding an 8-session virtual education intervention (AF-at-Home) during the early months of the COVID-19 pandemic.

METHODS

A qualitative study with 3 focus groups using a semistructured focus group guide was conducted and recorded online with the same trained moderator.

RESULTS

We identified 7 primary themes emerging from patients' experiences: (1) building knowledge beyond information available in clinic visits, (2) managing anxiety, (3) generating self-efficacy, (4) providing social comparison, (5) perceived benefits of both experiential and informational content, (6) facilitating self-management behaviors, and (7) facilitating communication with providers.

CONCLUSIONS

The analysis of the focus groups shows the benefits of a virtual education program in building knowledge, skills, and self-efficacy as well as reducing anxiety and normalizing one's experience by attending a program alongside other patients with AF.

Usability and Feasibility Testing of an Atrial Fibrillation Educational Website with Patients Referred to an Atrial Fibrillation Specialty Clinic

BACKGROUND

The purpose of this study was to design, usability test, and explore the feasibility of a web-based educational platform/intervention for patients with atrial fibrillation (AF) as part of their virtual AF care.

METHODS

Participants were patients attending a specialized AF clinic. The multiple mixed-methods design included website design, think-aloud usability test, 1-month unstructured pre-testing analysis using Google Analytics, follow-up interviews, and a non-randomized one-group feasibility test using pre/post online surveys and Google Analytics.

RESULTS

Usability testing participants (n = 2) guided adjustments for improving navigation. Pre-testing participants' (n = 9) website activity averaged four sessions (SD = 2.6) at 10 (SD 8) minutes per session during a 1-month study period. In the feasibility test, 30 patients referred to AF specialty clinic care completed the baseline survey, and 20 of these completed the 6-month follow-up survey. A total of 19 patients accessed the website over the 6 months, and all 30 participants were sent email prompts containing information from the website. Health-related quality of life, treatment satisfaction, household activity, and AF knowledge scores were higher at follow-up than baseline. There was an overall downward trend in self-reported healthcare utilization at follow-up.

CONCLUSIONS

Access to a credible education website for patients with AF has great potential to complement virtual and hybrid models of care.

Variations in Atrial Fibrillation Ablation Use and Charges in a Modern Cohort of Medicare Beneficiaries

Catheter ablation of atrial fibrillation (CAF) is increasingly being used in the United States. This study aimed to identify variations in CAF use among Medicare beneficiaries (MBs) over a 6-year period (2013 to 2019). Using the Center of Medicare and Medicaid Services database, a 100% sample of MBs who underwent CAF from 2013 to 2019 was included. We stratified CAF use data geographically (Northeast, South, West, and Midwest) and identified the number of CAFs per 100,000 MBs, number of electrophysiologists performing CAFs per 100,000 MBs, number of CAFs per individual electrophysiologist, and average submitted charge for CAF. In addition, we stratified the data per urban versus rural areas and gender of the operator. We found that the mean atrial fibrillation (AF) prevalence, rates of CAFs, number of electrophysiologists performing CAFs, and number of CAFs per electrophysiologist have increased steadily in all regions. The mean AF prevalence was different among regions, with the highest prevalence in the Northeast (p <0.001); however, there was a pattern of higher CAFs rates in the West and the South (p ≥0.057). The number of electrophysiologists performing CAFs was not different among regions; however, the number of CAFs per electrophysiologist was higher in the West and the South (p <0.001). The average submitted charge for CAF has decreased over years and was the lowest in the West and the South (p <0.001). There was no major difference in these variables regarding operator gender. In conclusion, there are significant variations in CAF use among MBs in the United States according to geographic and urban versus rural regions. These variations have the potential to impact the outcomes in MBs diagnosed with AF.

Exploring virtual care clinical experience from non-physician healthcare providers (VCAPE)

COVID-19 has caused an urgent implementation of virtual care (VC). Most research has focused on patient and physician experience with virtual care. Non-physician healthcare providers have played an active role in transitioning to virtual care, yet little is known about their experiences. This study explored their lived experiences in caring for patients virtually. Forty non-physician healthcare providers from local hospitals, community, and home care settings in Kingston, ON, Canada, participated and included nurse practitioners, occupational therapists, physiotherapists, psychologists, registered dietitians, social workers, and speech-language pathologists. Data were collected using semi-structured interviews between February and July 2021 and were analyzed thematically. The study was guided by organizational change theory. Four themes were identified from the data: 1) Quality of care, 2) Resources and training, 3) Healthcare system efficiency, and 4) Health equity and access for patients. Providers suggested that VC increased patient-centredness and had clear benefits for patients. Participants had little to no training in conducting patient care, virtually stating this as a key challenge. They believed that VC increased the efficiency of the healthcare system and was more proactive. Despite concerns regarding inequities across healthcare, participants reported that VC could improve equity as long as patients had access to technology. The study highlights the urgent need to support all healthcare providers in delivering optimal patient-centred care. We should leverage some of the advantages offered by VC to improve the efficiency of healthcare delivery, reduce provider burnout, and increase capacity across organizational systems.

Healthcare Resource Utilization in Patients with Newly Diagnosed Atrial Fibrillation: A Global Analysis from the GARFIELD-AF Registry

The management of atrial fibrillation (AF), the most common sustained arrhythmia, impacts healthcare resource utilization (HCRU). This study aims to estimate global resource use in AF patients, using the GARFIELD-AF registry. A prospective cohort study was conducted to characterize HCRU in AF patients enrolled in sequential cohorts from 2012 to 2016 in 35 countries. Components of HCRU studied were hospital admissions, outpatient care visits, and diagnostic and interventional procedures occurring during follow-up. AF-related HCRU was reported as the percentage of patients demonstrating at least one event and was quantified as rate-per-patient-per-year (PPPY) over time. A total of 49,574 patients was analyzed, having an overall median follow-up of 719 days. Almost all patients (99.5%) had at least one outpatient care visit, while hospital admissions were the second most frequent medical contact, with similar proportions in North America (37.5%) and Europe (37.2%), and slightly higher in the other GARFIELD-AF countries (42.0%; namely Australia, Egypt, and South Africa). Asia and Latin America showed lower percentages of hospitalizations, outpatient care visits, and diagnostic and interventional procedures. Analyses of GARFIELD-AF highlighted the vast AF-related HCRU, underlying significant geographical differences in the type, quantity, and frequency of AF-related HCRU. These differences were likely attributable to health service availability and differing models of care.

Consumer-Led Screening for Atrial Fibrillation: Frontier Review of the AF-SCREEN International Collaboration

The technological evolution and widespread availability of wearables and handheld ECG devices capable of screening for atrial fibrillation (AF), and their promotion directly to consumers, has focused attention of health care professionals and patient organizations on consumer-led AF screening. In this Frontiers review, members of the AF-SCREEN International Collaboration provide a critical appraisal of this rapidly evolving field to increase awareness of the complexities and uncertainties surrounding consumer-led AF screening. Although there are numerous commercially available devices directly marketed to consumers for AF monitoring and identification of unrecognized AF, health care professional-led randomized controlled studies using multiple ECG recordings or continuous ECG monitoring to detect AF have failed to demonstrate a significant reduction in stroke. Although it remains uncertain if consumer-led AF screening reduces stroke, it could increase early diagnosis of AF and facilitate an integrated approach, including appropriate anticoagulation, rate or rhythm management, and risk factor modification to reduce complications. Companies marketing AF screening devices should report the accuracy and performance of their products in high- and low-risk populations and avoid claims about clinical outcomes unless improvement is demonstrated in randomized clinical trials. Generally, the diagnostic yield of AF screening increases with the number, duration, and temporal dispersion of screening sessions, but the prognostic importance may be less than for AF detected by single-time point screening, which is largely permanent, persistent, or high-burden paroxysmal AF. Consumer-initiated ECG recordings suggesting possible AF always require confirmation by a health care professional experienced in ECG reading, whereas suspicion of AF on the basis of photoplethysmography must be confirmed with an ECG. Consumer-led AF screening is unlikely to be cost-effective for stroke prevention in the predominantly young, early adopters of this technology. Studies in older people at higher stroke risk are required to demonstrate both effectiveness and cost-effectiveness. The direct interaction between companies and consumers creates new regulatory gaps in relation to data privacy and the registration of consumer apps and devices. Although several barriers for optimal use of consumer-led screening exist, results of large, ongoing trials, powered to detect clinical outcomes, are required before health care professionals should support widespread adoption of consumer-led AF screening.

Telemedicine practices in adult patients with atrial fibrillation

BACKGROUND

Atrial fibrillation is a cardiac rhythm disorder associated with embolic stroke risk, decreased functional capacity, and worsening quality of life. Increasing patient access to atrial fibrillation specialists via telemedicine has the potential to improve patient outcomes.

OBJECTIVES

The purpose of this systematic review was to describe atrial fibrillation telehealth education treatment programs unrelated to postablation or early detection of atrial fibrillation.

DATA SOURCES

PubMed and CINAHL databases were searched using key terms identified by the authors and informed by a panel of clinicians with expertise in cardiac electrophysiology.

CONCLUSIONS

Little literature exists on educational telehealth programs for atrial fibrillation treatment unrelated to postablation or early detection of atrial fibrillation. Only three studies met our inclusion criteria. Three themes emerged from review of these studies: (a) atrial fibrillation requires specialty care that is difficult to obtain; (b) comprehensive atrial fibrillation education should include a broad overview of the condition, management options, stroke prevention, and symptom management; and (c) telemedicine is effective for diagnosing and managing atrial fibrillation.

IMPLICATIONS FOR PRACTICE

Telemedicine clinics for atrial fibrillation represent an emerging form of clinically important health care delivery. These clinics can potentially decrease wait time for specialty care access, reduce unnecessary emergency department visits, reduce stroke risk, and increase guideline adherence. Nurse practitioners are well suited to create and lead telemedicine atrial fibrillation clinics with relevant clinical expertise and collaborative skills.

Virtual Care With Digital Technologies for Rural Canadians Living With Cardiovascular Disease

Canada is a wealthy nation with a geographically diverse population, seeking health innovations to better serve patients in accordance with the Canada Health Act. In this country, population and geography converge with social determinants, policy, procurement regulations, and technological advances with the goal to achieve equity in the management and distribution of health care. Rural and remote patients are a vulnerable population; when managing chronic conditions like cardiovascular disease, there is currently inequity to accessing specialist physicians at the recommended frequency-increasing the likelihood of poor health outcomes. Ensuring equitable care for this population is an unrealized priority of several provincial and federal government mandates. Virtual care technology might provide practical, economical, and innovative solutions to remedy this discrepancy. We conducted a scoping review of the literature pertaining to the use of virtual care technologies to monitor patients living in rural areas of Canada with cardiovascular disease. A search strategy was developed to identify the literature specific to this context across 3 bibliographic databases. Two hundred thirty-two unique citations were ultimately assessed for eligibility, of which 37 met the inclusion criteria. In our assessment of these articles, we provide a summary of the interventions studied, their reported effectiveness in reducing adverse events and mortality, the challenges to implementation, and the receptivity of these technologies among patients, providers, and policy-makers. Furthermore, we glean insight into the barriers and opportunities to ensure equitable care for rural patients and conclude that there is an ongoing need for clinical trials on virtual care technologies in this context.

Deliver Cardiac Virtual Care (CVC) - A Primer for Cardiovascular Professionals in Canada

The COVID-19 pandemic, with its need for distancing, has necessitated the use of virtual care in never-before-seen volumes. This review article aims to provide a primer on virtual care for cardiovascular professionals in Canada. The technology to facilitate remote patient interactions is already available, but barriers exist. Adequate and effective cardiac virtual care must be further developed given the need for rapid evaluation and close ongoing follow-up of patients, as seen in the areas of management of heart failure, cardiac rehabilitation, electrophysiology, and hypertension. Many Canadian organizations have published resources to assist health care providers and patients navigate the unfamiliar virtual care landscape. Although there are concerns surrounding issues such as patient privacy, access to technology, language discrepancies, and billing, these deficits provide opportunities for growth by health care organizations and technology companies. The integration of virtual care, home-based devices, and disruptive technologies emphasize the trend toward virtualization of health care, with the potential for greater personalization of health care interactions and continuity of care. Funding models were rapidly developed at the beginning of the COVID-19 pandemic, and although some provinces have deemed these changes as permanent, the status from other provinces remains unknown. The foundations to support virtual care as a key modality for health care delivery in Canada have been built, and further developments may strengthen its viability as a long-term option.

Importance and Assessment of Quality of Life in Symptomatic Permanent Atrial Fibrillation: Patient Focus Groups from the RATE-AF Trial

AIMS

To establish the extent and impact of symptoms in patients with atrial fibrillation (AF), the importance of different aspects of quality of life (QoL), and how we should assess wellbeing.

METHODS

Focus groups of patients with symptomatic permanent AF in a trial of heart rate control; the RATE-AF trial randomised 160 patients aged ≥60 years with permanent AF and at least NYHA class II dyspnoea to either digoxin or beta-blockers. Patient and public representatives led the focus groups and performed all data acquisition and analysis, using thematic approaches to interpret patient views about QoL and its measurement.

RESULTS

Substantial impairment of health-related QoL was noted in 160 trial patients, with impact on all domains apart from mental health. Eight women and 11 men aged 61-87 years participated in the focus groups. Common themes were a lack of information from healthcare professionals about AF, a lack of focus on QoL in consultations, and a sense of frustration, isolation, and reduced confidence. There was marked variability in symptoms in individual patients, with some describing severe impact on activities of daily living, and profound interaction with comorbidities such as arthritis. Day-to-day variation in QoL and difficulty in attributing symptom burden to AF or other comorbidities led to challenges in questionnaire completion. Consensus was reached that collecting both general and AF-specific QoL would be useful in routine practice, along with participation in peer support, which was empowering for the patients.

CONCLUSIONS

The impact of comorbidities is poorly appreciated in the context of AF, with considerable variability in QoL that requires both generic and AF-specific assessment. Improvement in QoL should direct the appraisal, and reappraisal, of treatment decisions for patients with permanent AF.
