Atrial Fibrillation Treatment Pathway in the Emergency Department Reduces Median 30-Day Health Service Charges

BACKGROUND

The economic burden of atrial fibrillation (AF) continues to increase. AF treatment pathways have been shown to reduce avoidable admissions, but the effects on health care costs are not understood. This study sought to assess the impact of an AF treatment pathway on health service charges and emergency department (ED) discharge rates.

METHODS

An AF treatment pathway was implemented at 7 hospital EDs in North Carolina between 2017 and 2020. Thirty-day health service charges were calculated for ED visits, hospitalizations, and outpatient clinic appointments. A quasi-experimental design was used to assess changes in health service charges and ED discharge rates following implementation of the AF treatment pathway. Adjusted quantile and negative binomial regressions were used to analyze changes in median 30-day health service charges and discharge rates from the ED, respectively.

RESULTS

Among 12 504 patients that met eligibility for study inclusion (preperiod: n=3893; postperiod: n=8611), implementation of the AF treatment pathway significantly reduced 30-day health service charges (preperiod: $11 922; postperiod: $9219; P<0.001). In adjusted models, implementation of the AF treatment pathway was associated with an $834 decrease in median 30-day health service charges (95% CI, -$1630 to $-37; P=0.04). Additionally, the adjusted predicted probability of ED discharge increased from 65.3% to 70.0% after the AF treatment pathway implementation, a 4.7 percentage point increase (95% CI, 1.4-8.0; P<0.001).

CONCLUSIONS

The implementation of an AF treatment pathway in the ED was associated with a decrease in median 30-day health service charges and an increase in ED discharge rate for patients presenting with AF.

Modifiable risk factors and self-reported health after percutaneous coronary intervention: with and without a history of atrial fibrillation

AIMS

Atrial fibrillation (AF) and coronary artery disease have several common risk factors, and 10-15% of patients with AF undergo percutaneous coronary intervention (PCI). Little is known about changes over time in modifiable risk factors and self-reported health in patients with and without a history of AF after PCI. Therefore, the aims were to determine and compare changes in modifiable risk factors and self-reported health in patients with and without a history of AF after PCI.

METHODS AND RESULTS

CONCARDPCI, a prospective multi-centre cohort study including patients after PCI, was conducted at seven high-volume PCI centres in Norway and Denmark (n = 3417). Of these, 408 had a history of AF. Data collection was conducted at the index admission and at 2-, 6-, and 12 months after discharge. Self-reported health was assessed with RAND-12 and the myocardial infarction dimensional assessment scale. Patients with a history of AF reported poorer health at baseline. However, the physical (P = 0.012) and mental (P < 0.001) health improved over time in both groups. The patients with a history of AF reported more emotional reactions (P = 0.029) and insecurities (P = 0.015). The proportion of smokers increased from 2- to 12 months in patients with a history of AF (P = 0.041), however, decreased in patients without AF from baseline to 6 months (P < 0.001).

CONCLUSION

An intensified focus on lifestyle interventions is needed to improve modifiable risk factors and self-reported health in patients with and without a history of AF after PCI.

Rural-Urban Differences in Outcomes of Acute Cardiac Admissions in a Large Health Service

Background

Cardiovascular disease (CVD) is a leading cause of morbidity and mortality and residing in a rural and remote region is associated with an increased risk. The impact of rurality on CVD outcomes needs to be fully elucidated.

Objectives

The purpose of this study was to assess the difference in mortality, readmission within 30 days, total readmissions, survival, and total emergency department (ED) presentations following an index CVD admission among patients from rural or remote areas as compared to metropolitan areas.

Methods

This retrospective observational study included all index hospitalizations with heart failure (HF), atrial fibrillation (AF), or acute coronary syndrome (ACS) within the Hunter New England region of Australia, between January 1, 2008, and December 31, 2021.

Results

There were 27,995 ACS admissions, 15,586 HF admissions, and 16,935 AF admissions. Patients from a rural or remote area presenting with CVD presentations had increased 30-day readmission (OR: 1.19; P < 0.001), an increased number of readmissions (incident rate ratio: 1.19; P < 0.001), and more ED presentations (incident rate ratio: 1.39; P < 0.001) as compared to patients from metropolitan areas. This was consistent across patients presenting with ACS, HF, and AF. There was no difference in mortality (HR: 1.01; P = 0.515). However, in the ACS subgroup, there was increased mortality in the rural and remote population (HR: 1.05; P = 0.015).

Conclusions

This study highlights the increased incidence of ED presentations and hospital readmissions, for those living in rural Australia, illustrating the disparity in health care provided, and the ongoing need for interventions that address poorer access to specialized health care in the early discharge phase of hospitalization.

Managing elderly patients with atrial fibrillation and multimorbidity: call for a systematic approach

INTRODUCTION

Atrial fibrillation (AF) is often accompanied by comorbidities. Not only cardiovascular but also non-cardiovascular comorbidities have been associated with AF. Multimorbidity is therefore a common finding in patients with AF, especially in elderly patients. Multimorbidity is associated with adverse outcomes, adds complexity to AF management, and poses a significant burden on healthcare costs. It is expected that the prevalence of elderly patients with multimorbidity will increase significantly. It is therefore crucial to outline implications for clinical practice and guide comprehensive multimorbidity management.

AREAS COVERED

This perspective article outlines multimorbidity in AF and the importance of comprehensive comorbidity management. It addresses current clinical practice guided by international guidelines and the need for integrated care including a patient-centered focus, comprehensive AF management, coordinated multidisciplinary care, and supporting technology. Moreover, it proposes a novel model of care delivery following a systematic approach to multimorbidity management.

EXPERT OPINION

Providing comprehensive care by means of a multidisciplinary team and patient engagement is crucial to provide optimal personalized care for elderly patients with AF and multimorbidity. A systematic integrated care approach seems promising, but further studies are needed to investigate the feasibility of a systematic approach and prioritization of comorbidity management in patients with multimorbidity.

Clinical service organisation for adults with atrial fibrillation

BACKGROUND

Atrial fibrillation (AF) is an increasingly prevalent heart rhythm condition in adults. It is considered a common cardiovascular condition with complex clinical management. The increasing prevalence and complexity in management underpin the need to adapt and innovate in the delivery of care for people living with AF. There is a need to systematically examine the optimal way in which clinical services are organised to deliver evidence-based care for people with AF. Recommended approaches include collaborative, organised multidisciplinary, and virtual (or eHealth/mHealth) models of care.

OBJECTIVES

To assess the effects of clinical service organisation for AF versus usual care for people with all types of AF.

SEARCH METHODS

We searched the Cochrane Central Register of Controlled Trials (CENTRAL), MEDLINE, Embase, and CINAHL to October 2022. We also searched ClinicalTrials.gov and the WHO ICTRP to April 2023. We applied no restrictions on date, publication status, or language.

SELECTION CRITERIA

We included randomised controlled trials (RCTs), published as full texts and as abstract only, involving adults (≥ 18 years) with a diagnosis of any type of AF. We included RCTs comparing organised clinical service, disease-specific management interventions (including e-health models of care) for people with AF that were multicomponent and multidisciplinary in nature to usual care.

DATA COLLECTION AND ANALYSIS

Three review authors independently selected studies, assessed risk of bias, and extracted data from the included studies. We calculated risk ratio (RR) for dichotomous data and mean difference (MD) or standardised mean difference (SMD) for continuous data with 95% confidence intervals (CIs) using random-effects analyses. We then calculated the number needed to treat for an additional beneficial outcome (NNTB) using the RR. We performed sensitivity analyses by only including studies with a low risk of selection and attrition bias. We assessed heterogeneity using the I² statistic and the certainty of the evidence according to GRADE. The primary outcomes were all-cause mortality and all-cause hospitalisation. The secondary outcomes were cardiovascular mortality, cardiovascular hospitalisation, AF-related emergency department visits, thromboembolic complications, minor cerebrovascular bleeding events, major cerebrovascular bleeding events, all bleeding events, AF-related quality of life, AF symptom burden, cost of intervention, and length of hospital stay.

MAIN RESULTS

We included 8 studies (8205 participants) of collaborative, multidisciplinary care, or virtual care for people with AF. The average age of participants ranged from 60 to 73 years. The studies were conducted in China, the Netherlands, and Australia. The included studies involved either a nurse-led multidisciplinary approach (n = 4) or management using mHealth (n = 2) compared to usual care. Only six out of the eight included studies could be included in the meta-analysis (for all-cause mortality and all-cause hospitalisation, cardiovascular mortality, cardiovascular hospitalisation, thromboembolic complications, and major bleeding), as quality of life was not assessed using a validated outcome measure specific for AF. We assessed the overall risk of bias as high, as all studies had at least one domain at unclear or high risk of bias rating for performance bias (blinding) in particular. Organised AF clinical services probably result in a large reduction in all-cause mortality (RR 0.64, 95% CI 0.46 to 0.89; 5 studies, 4664 participants; moderate certainty evidence; 6-year NNTB 37) compared to usual care. However, organised AF clinical services probably make little to no difference to all-cause hospitalisation (RR 0.94, 95% CI 0.88 to 1.02; 2 studies, 1340 participants; moderate certainty evidence; 2-year NNTB 101) and may not reduce cardiovascular mortality (RR 0.64, 95% CI 0.35 to 1.19; 5 studies, 4564 participants; low certainty evidence; 6-year NNTB 86) compared to usual care. Organised AF clinical services reduce cardiovascular hospitalisation (RR 0.83, 95% CI 0.71 to 0.96; 3 studies, 3641 participants; high certainty evidence; 6-year NNTB 28) compared to usual care. Organised AF clinical services may have little to no effect on thromboembolic complications such as stroke (RR 1.14, 95% CI 0.74 to 1.77; 5 studies, 4653 participants; low certainty evidence; 6-year NNTB 588) and major cerebrovascular bleeding events (RR 1.25, 95% CI 0.79 to 1.97; 3 studies, 2964 participants; low certainty evidence; 6-year NNTB 556). None of the studies reported minor cerebrovascular events.

AUTHORS' CONCLUSIONS

Moderate certainty evidence shows that organisation of clinical services for AF likely results in a large reduction in all-cause mortality, but probably makes little to no difference to all-cause hospitalisation compared to usual care. Organised AF clinical services may not reduce cardiovascular mortality, but do reduce cardiovascular hospitalisation compared to usual care. However, organised AF clinical services may make little to no difference to thromboembolic complications and major cerebrovascular events. None of the studies reported minor cerebrovascular events. Due to the limited number of studies, more research is required to compare different models of care organisation, including utilisation of mHealth. Appropriately powered trials are needed to confirm these findings and robustly examine the effect on inconclusive outcomes. The findings of this review underscore the importance of the co-ordination of care underpinned by collaborative multidisciplinary approaches and augmented by virtual care.

Ross procedure or mechanical aortic valve, which is the best lifetime option for an 18-year-old? A decision analysis

Objectives

Identifying the optimal solution for young adults requiring aortic valve replacement (AVR) is challenging, given the variety of options and their lifetime complication risks, impacts on quality of life, and costs. Decision analytic techniques make comparisons incorporating these measures. We evaluated lifetime valve-related outcomes of mechanical aortic valve replacement (mAVR) versus the Ross procedure (Ross) using decision tree microsimulations modeling.

Methods

Transition probabilities, utilities, and costs derived from published reports were entered into a Markov model decision tree to explore progression between health states for hypothetical 18-year-old patients. In total, 20,000 Monte Carlo microsimulations were performed to model mortality, quality-adjusted-life-years (QALYs), and health care costs. The incremental cost-effectiveness ratio (ICER) was calculated. Sensitivity analyses was performed to identify transition probabilities at which the preferred strategy switched from baseline.

Results

From modeling, average 20-year mortality was 16.3% and 23.2% for Ross and mAVR, respectively. Average 20-year freedom from stroke and major bleeding was 98.6% and 94.6% for Ross, and 90.0% and 82.2% for mAVR, respectively. Average individual lifetime (60 postoperative years) utility (28.3 vs 23.5 QALYs) and cost ($54,233 vs $507,240) favored Ross over mAVR. The average ICER demonstrated that each QALY would cost $95,345 more for mAVR. Sensitivity analysis revealed late annual probabilities of autograft/left ventricular outflow tract disease and homograft/right ventricular outflow tract disease after Ross, and late death after mAVR, to be important ICER determinants.

Conclusions

Our modeling suggests that Ross is preferred to mAVR, with superior freedom from valve-related morbidity and mortality, and improved cost-utility for young adults requiring aortic valve surgery.

Cost-effectiveness of an inpatient nurse practitioner in heart failure

AIMS

Heart failure (HF) nurse practitioners (NPs) are an important part of the HF specialist team, and their impact on the cost-effectiveness of their role is unknown. The aim of this study was to determine the cost-effectiveness of a HF NP inpatient service compared with current practice of no HF NP service from a health system perspective at 12 months and 3 years.

METHODS AND RESULTS

We developed a Markov model to estimate costs, effects, and cost-effectiveness for hospitalized HF patients and seen by a HF NP service compared with usual care at 12 months and 3 years. Costs and effects were taken from a retrospective observational cohort study. Transition probabilities and utilities were derived from published studies. A total of 500 patients were included (250 patients in the HF NP service vs. 250 patients in usual care). Average age was 77.7 ± 11 years, and 54% were male. At 12 months, the HF NP group was cheaper and more effective compared with no HF NP [$23 031 vs. $25 111 (AUD), respectively; quality-adjusted life years (QALYs) were 0.68 in HF NP group compared with 0.66 in usual care]. The incremental cost-effectiveness ratio showed a savings of $109 474 per QALY gained at 12 months and a savings of $270 667 per QALY gained at 3 years in favour of the HF NP service.

CONCLUSION

The HF NP service was cost-effective with lower costs and higher QALYs compared with no HF NP service. Economic evaluations alongside randomized controlled trials are warranted.

Does a nurse-led interventional program improve clinical outcomes in patients with atrial fibrillation? A meta-analysis

BACKGROUND

Being the most common type of arrhythmia, atrial fibrillation (AF) is progressively increasing with an annual rate of 5 million new cases. Recent guidelines highlight the importance of using collaborative multidisciplinary teams in order to improve outcomes during management of patients with AF. A nurse-led program including a nurse-directed education, counselling and intervention has shown to improve patients' outcomes in candidates with AF. In this analysis, we aimed to systematically compare the clinical outcomes observed in patients with AF who were assigned to a nurse-led interventional program versus a usual care group.

METHODS

EMBASE, MEDLINE, Http://www.

CLINICALTRIALS

gov , Web of Science; Google Scholar and Cochrane databases were the data sources. The clinical outcomes were considered as the endpoints in this study. This is a meta-analysis, and the statistical analysis was conducted by the RevMan software (version 5.4). Risk ratios (RR) with 95% confidence intervals (CI) were used to represent the data after statistical analysis.

RESULTS

Six studies with a total number 2916 participants were included whereby 1434 participants were assigned to a nurse-led intervention and 1482 participants were assigned to the usual care group. Our results showed that participants with AF who were assigned to the nurse-led interventional group had a significantly lower risk of composite endpoints (RR: 0.82, 95% CI: 0.70-0.96; P = 0.01), heart failure (RR: 0.66, 95% CI: 0.47-0.92; P = 0.02), atrial fibrillation (RR: 0.77, 95% CI: 0.63-0.94; P = 0.01) and re-admission (RR: 0.78, 95% CI: 0.62-0.99; P = 0.04). However, the risks of all-cause mortality (RR: 0.86, 95% CI: 0.68-1.09; P = 0.21), cardiac death (RR: 0.67, 95% CI: 0.33-1.39; P = 0.28), myocardial infarction (RR: 0.70, 95% CI: 0.35-1.42; P = 0.33), stroke (RR: 0.75, 95% CI: 0.44-1.26; P = 0.28), all bleeding events (RR: 1.11, 95% CI: 0.81-1.53; P = 0.51) and major bleeding events (RR: 0.91, 95% CI: 0.56-1.49; P = 0.71) were not significantly different.

CONCLUSIONS

The nurse-led interventional program significantly improved composite endpoints including heart failure and the recurrence of AF, resulting in a significantly lower admission rate compared to the usual care group. However, nurse-led interventional program did not affect mortality, stroke, myocardial infarction and bleeding events. Based on our current results, a nurse-led interventional programs apparently could be beneficial in patients with AF. Future larger trials would be able to confirm this hypothesis.

Development and Feasibility of a Primary Care Provider Training Intervention to Improve Atrial Fibrillation Management

The disparities in atrial fibrillation (AF) care are partially attributed to inadequate access to providers with specialized training in AF. Primary care providers (PCPs) are often the sole providers of AF care in under-resourced regions. As such, we sought to create a virtual education intervention for PCPs and to evaluate its impact on the use of stroke risk reduction strategies in patients with AF. A multidisciplinary team mentored PCPs on AF management over 6 months using a virtual case-based training format. Surveys of participant knowledge and confidence in AF care were compared before and after the intervention. Hierarchical logistic regression modeling was used to evaluate change in oral anticoagulation (OAC) therapy in the patients seen by participants before or after training. Of 41 participants trained, 49% worked in family medicine, 41% internal medicine, and 10% general cardiology. Participants attended a mean of 14 1-hour sessions. Overall, the appropriate use of OAC (for CHA2DS2-VASc score ≥1 man, ≥2 women) increased from 37% to 46% (p <0.001) comparing the patients seen before (n = 1,739) versus after (n = 610) intervention. The factors independently associated with appropriate OAC use included participant training (odds ratio [OR] 1.4, p = 0.002) and participant competence in AF management. The factors associated with decreased OAC use included patient age (OR 0.8 per 10 year, p = 0.008) and nonwhite race (OR 0.7, p = 0.028). Provider knowledge and confidence in AF care improved (p <0.001). In conclusion, we show that a virtual PCP training intervention improves the use of stroke risk reduction therapy in outpatients with AF and could be a widely scalable intervention to improve AF care in under-resourced communities.

Nurse-led care after ablation of atrial fibrillation: a randomized controlled trial

AIMS

The added value of advanced practitioner nurse (APN) care after ablation of atrial fibrillation (AF) is unknown. The present study investigates the impact of APN-led care on AF recurrence, patient knowledge, lifestyle, and patient satisfaction.

METHODS AND RESULTS

Sixty-five patients undergoing AF ablation were prospectively randomized to usual care (N = 33) or intervention (N = 32) group. In addition to usual care, the intervention consisted of an educational session, three consultations spread over 6 months and telephone accessibility coordinated by the APN. Primary outcome was the AF recurrence rate at 6-month follow-up. Secondary outcomes were lifestyle factors (alcohol intake, exercise, BMI, smoking), patient satisfaction and AF knowledge measured at 1 and 6 months between groups and within each group. Study demographics at 1 month were similar, except AF knowledge was higher in the intervention group (8.6 vs. 7, P = 0.001). At 6 months, AF recurrence was significantly lower in the intervention group (13.5 vs. 39.4%, P = 0.014). Between groups, patient satisfaction and AF knowledge were significantly higher in the intervention group, respectively, 9.4 vs. 8.7 (P < 0.001) and 8.6 vs. 7.0 out of 10 (P < 0.001). Within the intervention group, alcohol intake decreased from 3.9 to 2.6 units per week (P = 0.031) and physical activity increased from 224.4 ± 210.7 to 283.8 ± 169.3 (P = 0.048). No changes occurred within the usual care group. Assignment to the intervention group was the only protective factor for AF recurrence [Exp(B) 0.299, P = 0.04] in multivariable-adjusted analysis.

CONCLUSION

Adding APN-led care after ablation of AF improves short-term clinical outcome, patient satisfaction and physical activity and decreases alcohol intake.

Cardiovascular outcomes of cancer patients in rural Australia

Background

Cancer and heart disease are the two most common health conditions in the world, associated with high morbidity and mortality, with even worse outcomes in regional areas. Cardiovascular disease is the leading cause of death in cancer survivors. We aimed to evaluate the cardiovascular outcomes of patients receiving cancer treatment (CT) in a regional hospital.

Methods

This was an observational retrospective cohort study in a single rural hospital over a ten-year period (17th February 2010 to 19th March 2019). Outcomes of all patients receiving CT during this period were compared to those who were admitted to the hospital without a cancer diagnosis.

Results

268 patients received CT during the study period. High rates of cardiovascular risk factors: hypertension (52.2%), smoking (54.9%), and dyslipidaemia (38.4%) were observed in the CT group. Patients who had CT were more likely to be readmitted with ACS (5.9% vs. 2.8% p = 0.005) and AF (8.2% vs. 4.5% p = 0.006) when compared to the general admission cohort. There was a statistically significant difference observed for all cause cardiac readmission, with a higher rate observed in the CT group (17.1% vs. 13.2% p = 0.042). Patients undergoing CT had a higher rate of mortality (49.5% vs. 10.2%, p ≤ 0.001) and shorter time (days) from first admission to death (401.06 vs. 994.91, p ≤ 0.001) when compared to the general admission cohort, acknowledging this reduction in survival may be driven at least in part by the cancer itself.

Conclusion

There is an increased incidence of adverse cardiovascular outcomes, including higher readmission rate, higher mortality rate and shorter survival in people undergoing cancer treatment in rural environments. Rural cancer patients demonstrated a high burden of cardiovascular risk factors.

The prognostic value of quality of life in atrial fibrillation on patient value

BACKGROUND

In this study, the prognostic value of AF-related quality of life (AFEQT) at baseline on Major Adverse Cardiovascular Events (MACE) and improvement of perceived symptoms (EHRA) was assessed. Furthermore, the relationship between QoL and AF-related hospitalizations was assessed.

METHODS

A cohort of AF-patients diagnosed between November 2014 and October 2019 in four hospitals embedded within the Netherlands Heart Network were prospectively followed for 12 months. MACE was defined as stroke, myocardial infarction, heart failure and/or mortality. Subsequently, MACE, EHRA score improvement and AF-related hospitalizations between baseline and 12 months of follow-up were recorded.

RESULTS

In total, 970 AF-patients were available for analysis. In analyses with patients with complete information on the confounder subset 36/687 (5.2%) AF-patients developed MACE, 190/432 (44.0%) improved in EHRA score and 189/510(37.1%) were hospitalized during 12 months of follow-up. Patients with a low AFEQT score at baseline more often developed MACE (OR(95%CI): 2.42(1.16-5.06)), more often improved in EHRA score (OR(95%CI): 4.55(2.45-8.44) and were more often hospitalized (OR(95%CI): 4.04(2.22-7.01)) during 12 months post diagnosis, compared to patients with a high AFEQT score at baseline.

CONCLUSIONS

AF-patients with a lower quality of life at diagnosis more often develop MACE, more often improve on their symptoms and also were more often hospitalized, compared to AF-patients with a higher quality of life. This study highlights that the integration of patient-reported outcomes, such as quality of life, has the potential to be used as a prognostic indicator of the expected disease course for AF.

Managing the Increasing Burden of Atrial Fibrillation through Integrated Care in Primary Care: A Cost-Effectiveness Analysis

Introduction

Integrated care for patients with atrial fibrillation (AF) in primary care reduced mortality compared to usual care. We assessed the cost-effectiveness of this approach.

Methods

Dutch primary care practices were randomised to provide integrated care for AF patients or usual care. A cost-effectiveness analysis was performed from a societal perspective with a 2-year time horizon to estimate incremental costs and Quality Adjusted Life Years (QALYs). A sensitivity analysis was performed, imputing missing questionnaires for a large group of usual care patients.

Results

522 patients from 15 intervention practices were compared to 425 patients from 11 usual care practices. No effect on QALYs was seen, while mean costs indicated a cost reduction between €865 (95% percentile interval (PI) -€5730 to €3641) and €1343 (95% PI -€6534 to €3109) per patient per 2 years. The cost-effectiveness probability ranged between 36% and 54%. In the sensitivity analysis, this increased to 95%-99%.

Discussion

Results should be interpreted with caution due to missing information for a large proportion of usual care patients.

Conclusion

The higher costs from extra primary care consultations were likely outweighed by cost reductions for other resources, yet this study doesn't give sufficient clarity on the cost-effectiveness of integrated AF care.

Development and Feasibility of a Primary Care Provider Training Intervention to Improve Atrial Fibrillation Management

Background

Disparities in atrial fibrillation (AF) care are partially attributed to inadequate access to providers with specialized training in AF. Primary care providers (PCPs) are often the sole providers of AF care in under-resourced regions.

Objective

To create a virtual education intervention for PCPs and evaluate its impact on use of stroke risk reduction strategies in AF patients.

Methods

A multi-disciplinary team mentored PCPs on AF management over 6 months using a virtual case-based training format. Surveys of participant knowledge and confidence in AF care were compared pre- and post-intervention. Hierarchical logistic regression modeling was used to evaluate change in stroke risk reduction therapies among patients seen by participants before or after training.

Results

Of 41 participants trained, 49% worked in family medicine, 41% internal medicine, and 10% general cardiology. Participants attended a mean of 14 one-hour sessions. Overall, appropriate use of oral anticoagulation (OAC) therapy (CHA 2 DS 2 -VASc score ≥1 men, ≥2 women) increased from 37% to 46% (p<.001) comparing patients seen pre- (n=1739) to post- (n=610) intervention. Factors independently associated with appropriate OAC use included participant training (OR 1.4, p=.002) and participant competence in AF management (by survey). Factors associated with decreased OAC use included patient age (OR 0.8 per 10 years, p=.008), nonwhite race (OR 0.7, p=.028). Provider knowledge and confidence in AF care both improved (p<.001).

Conclusions

A virtual case-based PCP training intervention improved use of stroke risk reduction therapy in outpatients with AF. This widely scalable intervention could improve AF care in under-resourced communities.

CONDENSED ABSTRACT

A virtual educational model was developed for primary care providers to improve competency in AF care in their community. Following a 6-month training intervention, the rate of appropriate oral anticoagulation (OAC) therapy among patients cared for by participating providers increased from 37% to 46% (p<.001). Among participants, knowledge and confidence in AF care improved. These findings suggest a virtual AF training intervention can improve PCP competency in AF care. This widely scalable intervention could help improve AF care in under-resourced communities.

Association of Neighborhood-Level Material Deprivation With Atrial Fibrillation Care in a Single-Payer Health Care System: A Population-Based Cohort Study

BACKGROUND

There are limited data on the association of material deprivation with clinical care and outcomes after atrial fibrillation (AF) diagnosis in jurisdictions with universal health care.

METHODS

This was a population-based cohort study of individuals ≥66 years of age with first diagnosis of AF between April 1, 2007, and March 31, 2019, in the Canadian province of Ontario, which provides public funding and prohibits private payment for medically necessary physician and hospital services. Prescription medications are subsidized for residents >65 years of age. The primary exposure was neighborhood material deprivation, a metric derived from Canadian census data to estimate inability to attain basic material needs. Neighborhoods were categorized by quintile from Q1 (least deprived) to Q5 (most deprived). Cause-specific hazards regression was used to study the association of material deprivation quintile with time to AF-related adverse events (death or hospitalization for stroke, heart failure, or bleeding), clinical services (physician visits, cardiac diagnostics), and interventions (anticoagulation, cardioversion, ablation) while adjusting for individual characteristics and regional cardiologist supply.

RESULTS

Among 347 632 individuals with AF (median age 79 years, 48.9% female), individuals in the most deprived neighborhoods (Q5) had higher prevalence of cardiovascular disease, risk factors, and noncardiovascular comorbidity relative to residents of the least deprived neighborhoods (Q1). After adjustment, Q5 residents had higher hazards of death (hazard ratio [HR], 1.16 [95% CI, 1.13-1.20]) and hospitalization for stroke (HR, 1.16 [95% CI, 1.07-1.27]), heart failure (HR, 1.14 [95% CI, 1.11-1.18]), or bleeding (HR, 1.16 [95% CI, 1.07-1.25]) relative to Q1. There were small differences across quintiles in primary care physician visits (HR, Q5 versus Q1, 0.91 [95% CI, 0.89-0.92]), echocardiography (HR, Q5 versus Q1, 0.97 [95% CI, 0.96-0.99]), and dispensation of anticoagulation (HR, Q5 versus Q1, 0.97 [95% CI, 0.95-0.98]). There were more prominent disparities for Q5 versus Q1 in cardiologist visits (HR, 0.84 [95% CI, 0.82-0.86]), cardioversion (HR, 0.80 [95% CI, 0.76-0.84]), and ablation (HR, 0.45 [95% CI, 0.30-0.67]).

CONCLUSIONS

Despite universal health care and prescription medication coverage, residents of more deprived neighborhoods were less likely to visit cardiologists or receive rhythm control interventions after AF diagnosis, even though they exhibited higher cardiovascular disease burden and higher risk of adverse outcomes.

Heart Rhythm Society Atrial Fibrillation Centers of Excellence Study: A survey analysis of stakeholder practices, needs, and barriers

BACKGROUND

An integrated, coordinated, and patient-centered approach to atrial fibrillation (AF) care delivery may improve outcomes and reduce cost.

OBJECTIVE

The purpose of this study was to gain a better understanding from key stakeholder groups on current practices, needs, and potential barriers to implementing optimal integrated AF care.

METHODS

A series of comprehensive questionnaires were designed by the Heart Rhythm Society Atrial Fibrillation Centers of Excellence (CoE) Task Force to conduct surveys with physicians, advanced practice professionals, patients, and hospital administrators. Data collected focused on the following areas: access to care, stroke prevention, education, AF quality improvement, and AF CoE needs and barriers. Survey responses were collated and analyzed by the Task Force.

RESULTS

The surveys identified 5 major unmet needs: (1) Standardized protocols, order sets, or care pathways in the emergency department or inpatient setting were uncommon (36%-42%). (2) All stakeholders agreed stroke prevention was a top priority; however, prior bleeding or risk of bleeding was the most frequent barrier for initiation. (3) Patients indicated that education on modifiable causes, AF-related complications, and lowering stroke risk is most important. (4) Less than half (43%) of the health care systems track patients with AF or treatment status. Patients reported that stroke and heart failure prevention and access to procedures were priority areas for an AF CoE. The most common barriers to implementing AF CoE identified by clinicians were administrative support (69%) and cost (52%); administrators reported physical space (43%).

CONCLUSION

On the basis of the findings of this study, the Task Force identified high priority areas to develop initiatives to aid the implementation of AF CoE.

Assessment of Primary Health Care Specialized Reference Clinics in Riyadh First Health Cluster: Outcome, Cost-Effectiveness and Patient Satisfaction

Purpose

The objectives of the study are to assess the outcome and cost-effectiveness of specialized reference clinics (SRCs) in primary health care centers (PHCCs) of Riyadh First Health Cluster (RFHC), then to estimate the patient satisfaction among clients utilizing such SRCs.

Patients and Methods

This facility-based study was conducted in Riyadh city, Saudi Arabia among six PHCCs in RFHC that contain SRCs. Records of all patients utilizing SRCs and their referral information were studied along two years. An in-depth interview was conducted with health care providers in SRCs. Cost analysis was calculated by the financial support group within RFHC. Also, a randomly selected 400 subjects utilizing SRCs were asked to fill patient satisfaction questionnaire.

Results

Over two years, a total number of 55,084 patients utilized SRCs among different specialties. Most of these patients (86.7%) had full medical service within PHC-SRCs with no need for referral to hospitals. SRCs are significantly effective in decreasing the burden on hospitals in most specialties (p < 0.001). This effectiveness is significantly increased during the 2nd year of service. The time spent until appointment is significantly reduced from an average of six weeks in hospitals to an average of one week in SRCs. SRCs are very cost-effective as they reduced referrals to hospitals by 86.7% among 55,084 patients who utilized SRCs over two years, saving total costs of about 14.08 million Saudi Riyals (3.75 million US dollars). Most of the specialties are cost-effective except for urology and general surgery clinics, which are not cost-effective. Patient satisfaction is high regarding all service domains. The overall patient satisfaction score increased from 71.4% in the 1st year up to 73.2% in the second year.

Conclusion

PHC-SRCs are cost-effective health services and their creation is reasonable and beneficial in terms of reducing costs of health care delivery, reducing the burden on hospitals, and improving patient satisfaction.

A Systematic Review of Economic Aspects of Service Interventions to Increase Anticoagulation Use in Atrial Fibrillation

OBJECTIVE

To systematically identify and appraise existing evidence surrounding economic aspects of anticoagulation service interventions for patients with atrial fibrillation.

METHODS

We searched the published and grey literature up to October 2019 to identify relevant economic evidence in any health care setting. A narrative-synthesis approach was taken to summarise evidence by economic design and type of service intervention, with costs expressed in pound sterling and valued at 2017 to 2018 prices.

RESULTS

A total of 13 studies met our inclusion criteria from 1,168 papers originally identified. Categories of interventions included anticoagulation clinics (n = 4), complex interventions (n = 4), decision support tools (n = 3) and patient-centred approaches (n = 2). Anticoagulation clinics were cost-saving compared with usual care (range for mean cost difference: £188-£691 per-patient per-year) with equivalent health outcomes. Only one economic evaluation of a complex intervention was conducted; case management was more expensive than usual care (mean cost difference: £255 per-patient per-year) and the probability of its cost-effectiveness did not exceed 70%. There was limited economic evidence surrounding decision support tools or patient-centred approaches. Targeting service interventions at high-risk groups and those with suboptimal treatment was most likely to result in cost savings.

CONCLUSION

This review revealed some evidence to support the cost-effectiveness of anticoagulation clinics. However, summative conclusions are constrained by a paucity of economic evidence, a lack of direct comparisons between interventions, and study heterogeneity in terms of intervention, comparator and study year. Further research is urgently needed to inform commissioning and service development. Data from this review can inform future economic evaluations of anticoagulation service interventions.

Care and referral patterns in a large, dedicated nurse-led atrial fibrillation outpatient clinic

Introduction

Atrial fibrillation (AF) is the most common arrhythmia and imposes a high burden on the healthcare system. A nurse-led AF outpatient clinic may alleviate the burden on the cardiology outpatient clinic by triaging patients who need care by a cardiologist or general practitioner (GP). However, care and referral patterns after initial assessment in a nurse-led AF outpatient clinic are unknown. We examined the proportion of AF patients assessed in a nurse-led clinic without outpatient follow-up by a cardiologist.

Methods

All patients with AF referred to our tertiary medical centre underwent cardiac work-up in the nurse-led AF outpatient clinic and were prospectively followed. Data on patient characteristics, rhythm monitoring and echocardiography were collected and described. Odds ratio (OR) for continuing care in the nurse-led AF outpatient clinic was calculated.

Results

From 2014 to 2018, 478 consecutive individual patients were referred to the nurse-led AF outpatient clinic. After the initial cardiac work-up, 139 patients (29.1%) remained under nurse-led care and 121 (25.3%) were referred to a cardiologist and 218 (45.6%) to a GP. Patients who remained under nurse-led care were significantly younger, were more symptomatic, more often had paroxysmal AF and had less comorbidities than the other two groups. After multivariable testing, CHA₂DS₂-VASc score ≥ 2 was associated with discontinued nurse-led care (OR 0.57, 95% confidence interval 0.34–0.95).

Conclusion

After initial cardiac assessment in the nurse-led outpatient clinic, about half of the newly referred AF patients were referred back to their GP. This strategy may reduce the burden of AF patients on secondary or tertiary cardiology outpatient clinics.

Association of income and educational attainment in hospitalization events in atrial fibrillation

OBJECTIVE

Social determinants contribute to adverse outcomes in cardiovascular and non-cardiovascular conditions. However, their investigation in atrial fibrillation (AF) remains limited. We examined the associations between annual income and educational attainment with risk of hospitalization in individuals with AF receiving care in a regional health care system. We hypothesized that individuals with lower income and lower education would have an increased risk of hospitalization.

METHODS

We enrolled a cohort of individuals with prevalent AF from an ambulatory setting. We related annual income (≤$19,999/year; $20,000-49,000/year; $50,000-99,999/year; ≥$100,000/year) and educational attainment (high school/vocational; some college; Bachelor's; graduate) to hospitalization events in multivariable-adjusted Cox proportional hazards models, using the Andersen-Gill model to account for the potential of participants to have multiple events.

RESULTS

In 339 individuals with AF (age 72.3 ± 10.1 years; 43% women) followed for median 2.6 years (range 0-3.4 years), we observed 417 hospitalization events. We identified an association between both income and educational attainment and hospitalization risk. In multivariable-adjusted analyses which included educational attainment individuals in the lowest annual income category (≤19,999/year) had 2.0-fold greater hospitalization risk than those in the highest (≥100,000/year; 95% Confidence Interval [CI] 1.08-4.09; p = 0.03). In multivariable-adjusted analyses without adjustment for income, those in the lowest educational attainment category (high school/vocational) had a 2-fold increased risk of hospitalization relative to the highest (graduate-level; 95% CI 1.12-3.54, p = 0.02). However, this association between education and events was attenuated with further adjustment for income (95% CI 0.97-3.15, p = 0.06).

CONCLUSIONS

We identified relationships between income and education and prospective risk of hospitalization risk in AF. Our findings support the consideration of social determinants in evaluating and treating socioeconomically disadvantaged individuals with AF to reduce hospitalization risk.

Research Priorities in the Secondary Prevention of Atrial Fibrillation: A National Heart, Lung, and Blood Institute Virtual Workshop Report

There has been sustained focus on the secondary prevention of coronary heart disease and heart failure; yet, apart from stroke prevention, the evidence base for the secondary prevention of atrial fibrillation (AF) recurrence, AF progression, and AF-related complications is modest. Although there are multiple observational studies, there are few large, robust, randomized trials providing definitive effective approaches for the secondary prevention of AF. Given the increasing incidence and prevalence of AF nationally and internationally, the AF field needs transformative research and a commitment to evidenced-based secondary prevention strategies. We report on a National Heart, Lung, and Blood Institute virtual workshop directed at identifying knowledge gaps and research opportunities in the secondary prevention of AF. Once AF has been detected, lifestyle changes and novel models of care delivery may contribute to the prevention of AF recurrence, AF progression, and AF-related complications. Although benefits seen in small subgroups, cohort studies, and selected randomized trials are impressive, the widespread effectiveness of AF secondary prevention strategies remains unknown, calling for development of scalable interventions suitable for diverse populations and for identification of subpopulations who may particularly benefit from intensive management. We identified critical research questions for 6 topics relevant to the secondary prevention of AF: (1) weight loss; (2) alcohol intake, smoking cessation, and diet; (3) cardiac rehabilitation; (4) approaches to sleep disorders; (5) integrated, team-based care; and (6) nonanticoagulant pharmacotherapy. Our goal is to stimulate innovative research that will accelerate the generation of the evidence to effectively pursue the secondary prevention of AF.

Risk factor management and atrial fibrillation

The management of atrial fibrillation (AF) is multifaceted and treatment paradigms have changed significantly in the last century. The treatment of AF requires a comprehensive approach which goes beyond the treatment of the arrhythmia alone. Risk factor management has been introduced as a crucial pillar of AF management. As a result, the landscape of care delivery is changing as well, and novel models of comprehensive care delivery for AF have been introduced. This article reviews the evidence for the role of risk factor management in AF, how this can be integrated and implemented in clinical practice by applying novel models of care delivery, and finally identifies areas for ongoing research and potential healthcare reform to comprehensively manage the burgeoning AF population.

Cost Analysis of a Dedicated Outpatient Clinic in Patients With Newly Diagnosed Atrial Fibrillation

AIMS

The aim of this study was to assess healthcare utilization costs of a dedicated outpatient clinic for patients with atrial fibrillation (AF).

METHODS

We conducted a registry-based retrospective study in patients with a first-time AF diagnosis from 2009 to 2011 (control group) and 2013 to 2015 (intervention group). The control group had physician-led usual care, and the intervention group received multidisciplinary care. The primary outcome was total costs of AF-related resource utilization. Exploratory outcomes were ischemic stroke, intracranial hemorrhage, and all-cause mortality. Multiple regression methods were used to control for confounders in the assessment of effects on outcomes.

RESULTS

A total of 1552 patients were included, hereof 850 in the intervention group. Total AF-related costs were €2746 for the control group and €3154 for the intervention group, which was not statistically significant. Average outpatient costs were significantly higher in the control group than in the intervention group (€522 vs €344, respectively; P = .003). There was no difference in the number of AF-related hospital admissions and outpatient visits between the control group and the intervention group (incidence risk ratio, 1.03 vs 0.85; and 95% confidence interval, 0.92-1.16 vs 0.69-1.05, respectively). There was a trend toward reduced all-cause mortality (hazard ratio, 0.86; 95% confidence interval, 0.63-1.16) in the intervention group, which was not statistically significant.

CONCLUSION

Total expenses for AF-related hospital resource utilization in the intervention group were higher, but the expenses for AF-related outpatient visits were significantly lower. There was a trend toward lower all-cause mortality in the intervention group, although the differences were not statistically significant. More research is needed investigating whether a multidisciplinary AF clinic is cost-effective.

A Team-Based Approach Toward Risk Factors of Atrial Fibrillation

Atrial fibrillation (AF), being the most common arrhythmia, the service of primary care physicians and internists in preventing, identifying, and treating AF is of paramount importance. There are nonmodifiable, modifiable, and reversible risk factors for AF. The modifiable risk factors include hypertension, obesity, coronary artery disease, heart failure, diabetes mellitus etc. These risk factors should be screened and adequately treated to prevent occurrence of AF at the primary care level itself. This will reduce recurrence rates of AF and will treat underlying conditions predisposing to AF.

The 2020 Canadian Cardiovascular Society/Canadian Heart Rhythm Society Comprehensive Guidelines for the Management of Atrial Fibrillation

The Canadian Cardiovascular Society (CCS) atrial fibrillation (AF) guidelines program was developed to aid clinicians in the management of these complex patients, as well as to provide direction to policy makers and health care systems regarding related issues. The most recent comprehensive CCS AF guidelines update was published in 2010. Since then, periodic updates were published dealing with rapidly changing areas. However, since 2010 a large number of developments had accumulated in a wide range of areas, motivating the committee to complete a thorough guideline review. The 2020 iteration of the CCS AF guidelines represents a comprehensive renewal that integrates, updates, and replaces the past decade of guidelines, recommendations, and practical tips. It is intended to be used by practicing clinicians across all disciplines who care for patients with AF. The Grading of Recommendations, Assessment, Development and Evaluations (GRADE) system was used to evaluate recommendation strength and the quality of evidence. Areas of focus include: AF classification and definitions, epidemiology, pathophysiology, clinical evaluation, screening and opportunistic AF detection, detection and management of modifiable risk factors, integrated approach to AF management, stroke prevention, arrhythmia management, sex differences, and AF in special populations. Extensive use is made of tables and figures to synthesize important material and present key concepts. This document should be an important aid for knowledge translation and a tool to help improve clinical management of this important and challenging arrhythmia.

Healthcare costs and resource utilization associated with treatment of out-of-hospital cardiac arrest

BACKGROUND

The management of out-of-hospital cardiac arrest (OHCA) patients requires the coordination of prehospital, in-hospital and post-discharge teams. Data reporting a comprehensive analysis of all costs associated with treating OHCA are scarce. We aimed to describe the total costs (and their components) related to the management of OHCA patients.

PATIENT AND METHODS

We performed an analysis on a merged database of the Toronto Regional RescuNet Epistry database (prehospital data) and administrative population-based databases in Ontario. All non-traumatic OHCA patients over 18 years of age treated by the EMS between January 1, 2006, and March 31, 2014, were included in this study. The primary outcome was per patient longitudinal cumulative healthcare costs, from time of collapse to a maximum follow-up until death or 30 days after the event. We included all available cost sectors, from the perspective of the health system payer. We used multivariable generalized linear models with a logarithmic link and a gamma distribution to determine predictors of healthcare costs.

RESULTS

25,826/44,637 patients were treated by EMS services for an OHCA (mostly male 64.4%, mean age 70.1). 11,727 (45%) were pronounced dead on scene, 8359 (32%) died in the emergency department, 3640 (14%) were admitted to hospital but died before day-30, and 2100 (8.1%) were still alive at day-30. Total cost was $690 [interquartile range (IQR) $308, $1742] per patient; ranging from $290 [IQR $188, $390] for patients who were pronounced on scene to $39,216 [IQR 21,802, 62,093] for patients who were still alive at day-30. In-hospital costs accounted for 93% of total costs. After adjustment for age and gender, rate of patient survival was the main driver of total costs: the rate ratio was 3.88 (95% confidence interval 3.80, 3.95), 49.46 and 148.89 for patients who died in the ED, patients who died after the ED but within 30 days, and patients who were still alive at day-30 compared to patients who were pronounced dead on scene, respectively. Factors independently associated with costs were the number of prehospital teams (rate ratio (RR) 5.50 [5.32, 5.67] for being treated by 4 teams vs. 1), the need for hospital transfer (RR 2.38 [2.01, 2.82]), coronary angiography (RR 1.43 [1.27, 1.62]) and targeted temperature management (RR 1.25 [1.09, 1.44]).

CONCLUSION

Survival is the main driver of total costs of treating OHCA patients in a large Canadian health system. Inpatient costs accounted for the majority of the total costs; potentially modifiable factors include the number of prehospital teams that arrive to the scene of the arrest and the need for between-hospital transfers after successful resuscitation.

An Atrial Fibrillation Transitions of Care Clinic Improves Atrial Fibrillation Quality Metrics

OBJECTIVES

This study sought to assess whether an atrial fibrillation (AF)-specific clinic is associated with improved adherence to American College of Cardiology (ACC)/American Heart Association (AHA) clinical performance and quality measures for adults with AF or atrial flutter.

BACKGROUND

There are significant gaps in care of patients with AF, including underprescription of anticoagulation and treatment of AF risk factors. An AF specialized clinic was developed to reduce admissions for AF but may also be associated with improved quality of care.

METHODS

This retrospective study compared adherence to ACC/AHA measures for patients who presented to the emergency department for AF between those discharged to a typical outpatient appointment and those discharged to a specialized AF transitions clinic run by an advanced practice provider and supervised by a cardiologist. Screening and treatment for common AF risk factors was also assessed.

RESULTS

The study enrolled 78 patients into the control group and 160 patients into the intervention group. Patients referred to the specialized clinic were more likely to have stroke risk assessed and documented (99% vs. 26%; p < 0.01); be prescribed appropriate anticoagulation (97% vs. 88%; p = 0.03); and be screened for comorbidities such as tobacco use (100% vs. 14%; p < 0.01), alcohol use (92% vs. 60%; p < 0.01), and obstructive sleep apnea (90% vs. 13%; p < 0.01) and less likely to be prescribed an inappropriate combination of anticoagulant and antiplatelet medications (1% vs. 9%; p < 0.01).

CONCLUSIONS

An AF specialized clinic was associated with improved adherence to ACC/AHA clinical performance and quality measures for adult patients with AF.

Guideline-directed therapies for comorbidities and clinical outcomes among individuals with atrial fibrillation

BACKGROUND

Comorbidities are common in patients with atrial fibrillation (AF) and affect prognosis, yet are often undertreated. However, contemporary rates of use of guideline-directed therapies (GDT) for non-AF comorbidities and their association with outcomes are not well described.

METHODS

We used the Outcomes Registry for Better Informed Treatment of AF (ORBIT-AF) to test the association between GDT for non-AF comorbidities and major adverse cardiac or neurovascular events (MACNE; cardiovascular death, myocardial infarction, stroke/thromboembolism, or new-onset heart failure), all-cause mortality, new-onset heart failure, and AF progression. Adjustment was performed using Cox proportional hazards models and logistic regression.

RESULTS

Only 6,782 (33%) of the 20,434 patients eligible for 1 or more GDT for non-AF comorbidities received all indicated therapies. Use of all comorbidity-specific GDT was highest for patients with hyperlipidemia (75.6%) and lowest for those with diabetes mellitus (43.1%). Use of "all eligible" GDT was associated with a nonsignificant trend toward lower rates of MACNE (HR 0.90 [0.79-1.02]) and all-cause mortality (HR 0.90 [0.80-1.01]). Use of GDT for heart failure was associated with a lower risk of all-cause mortality (HR 0.77 [0.67-0.89]), and treatment of obstructive sleep apnea was associated with a lower risk of AF progression (OR 0.75 [0.62-0.90]).

CONCLUSIONS

In AF patients, there is underuse of GDT for non-AF comorbidities. The association between GDT use and outcomes was strongest in heart failure and obstructive sleep apnea patients where use of GDT was associated with lower mortality and less AF progression.

Cost-Effectiveness of Advanced Practice Nurses Compared to Physician-Led Care for Chronic Diseases: A Systematic Review

Globally, advanced practice nurses (APNs) provide high-quality chronic disease care to patients, yet the cost-effectiveness of their services is minimally explored. This review aims to determine the cost-effectiveness of chronic disease care provided by APNs compared to physicians globally.

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

Background

Atrial fibrillation (AF) is a serious heart arrhythmia associated with devastating outcomes such as stroke. Inequitable rural AF care may put patients at risk. Virtually delivered specialty AF care offers a viable option, but stakeholder perceptions of this option within the context of rural AF care is unknown. The study purpose was to obtain patient and primary care physician perspectives of rural AF care and virtually delivered AF care as a potential option.

Methods

Using a mixed methods design, AF patients (n = 101) and physicians (n = 15) from three rural communities participated in focus groups and/or surveys. Focus group data were thematically analyzed, survey data were descriptively analyzed, and data were triangulated.

Results

Findings captured patients’ and physicians’ perceptions of prioritized, needs, concerns and problems in AF management, available/unavailable services, and their ideas about virtual AF care. Patients and physicians identified eclectic problems in managing AF. Overall, patients felt ill informed about managing their AF and their most salient problems related to fatigue, exercise intolerance, weight maintenance, sleep apnea, and worry about stroke and bleeding. Physicians found treating patients with co-morbidities and cognitive decline problematic and balancing risks related to anticoagulation challenging. Patients and physicians identified education as a pressing need, which physicians lacked time and resources to meet. Despite available rural services, access to primary and cardiology care was a recurring challenge, and emergency department (ED) use highly contentious but often the only option for accessing care. Physicians’ managed AF care and varied in the referrals they made, often reserving them for complex situations to avoid patient travel. Patients and providers supported a broad approach to virtual AF care, tailored to an inclusive rural patient demographic.

Conclusions

The study offered valuable physician and patient perspectives on AF care in rural communities including diverse management challenges, gaps in access to primary and specialty services that made ED an often used but contentious option. Findings point to the potential value of virtual care designed to reach patients with AF across the spectrum and geared to local contexts that preserve the vital role of primary care physicians in AF care in their communities.

Within trial cost-utility analysis of disease management program for patients hospitalized with atrial fibrillation: results from the SAFETY trial

Background: The potential impact of disease management to optimize quality of care, health outcomes, and total healthcare costs across a range of cardiac disease states is unknown. Methods: A trial-based cost-utility analysis was conducted alongside a randomized controlled trial of 335 patients with chronic, non-valvular AF (without heart failure; the SAFETY Trial) discharged to home from three tertiary referral hospitals in Australia. A home-based disease management intervention (the SAFETY intervention) that involved community-based AF care including home visits was compared to routine primary healthcare and hospital outpatient follow-up (standard management). Bootstrapped incremental cost-utility ratios were computed based on quality-adjusted life-years (QALYs) and total healthcare costs. Cost-effectiveness acceptability curves were constructed to explore the probability of the SAFETY intervention being cost-effective. Sub-group analyses were performed based on age and sex to determine differential cost-effectiveness. Results: During median follow-up of 1.75 years, the SAFETY intervention was associated with a non-statistically significant increase in QALYs (0.02 per person) and lower total healthcare costs (-$4,375 per person). Although each of these findings were not statistically significant, the SAFETY intervention was found to be dominant (more effective and cost saving) in 58.8% of the bootstrapped iterations and cost-effective (more effective and gains in QALYs achieved at or below $50,000 per QALY gained) in 61.5% of the iterations. Males and those aged less than 78 years achieved greater gains in QALYs and savings in healthcare costs. The estimated value of perfect information in Australia (the monetized value of removing uncertainty in the cost-effectiveness results) was A$51 million, thus demonstrating the high potential gain from further research. Conclusions: Compared with standard management, the SAFETY intervention is potentially a dominant strategy for those with chronic, non-valvular AF. However, there would be substantial value in reducing the uncertainty in these estimates from further research.

Promoting a sense of security in everyday life-A case study of patients and professionals moving towards co-production in an atrial fibrillation "learning café"

BACKGROUND

An improvement initiative sought to improve care for atrial fibrillation (AF) patients; many felt insecure about how to cope with AF.

OBJECTIVE

To reveal AF patients' and professionals' experiences of pilot-testing a Learning Café group education programme, aimed at increasing the patients' sense of security in everyday life.

DESIGN

Using an organizational case study design, we combined quantitative data (patients' sense of security) and qualitative data (project documentation; focus group interviews with five patients and five professionals) analysed using inductive qualitative content analysis.

SETTING

AF patients and a multiprofessional team at a cardiac care unit in a Swedish district hospital.

IMPROVEMENT ACTIVITIES

Two registered nurses invited AF patients and partners to four 2.5-hour Learning Café sessions. In the first session, they solicited participants' questions about life with AF. A physician, a registered nurse and a physiotherapist were invited to address these questions in the remaining sessions.

RESULTS

AF patients reported gaining a greater sense of security in everyday life and anticipating a future shift from emergency care to planned care. Professionals reported enhanced professional development, learning more about person-centredness and gaining greater control of their own work situation. The organization gained knowledge about patient and family involvement.

CONCLUSIONS

The Learning Café pilot test-exemplifying movement towards co-production through patient-professional collaboration-generated positive outcomes for patients (sense of security), professionals (work satisfaction; learning) and the organization (better care) in line with contemporary models for quality improvement and with Self-Determination Theory. This approach merits further testing and evaluation in other contexts.

Regional collaboration to improve atrial fibrillation care: Preliminary data from the Netherlands heart network

BACKGROUND

Guideline non-adherence and variations in therapeutic and diagnostic trajectories result in suboptimal atrial fibrillation (AF) treatments. Large academic and referral hospitals demonstrated positive effects of dedicated outpatient AF clinics. Although similar results have not been indicated in (small) non-academic hospitals yet, ample opportunities are present when collaboration is initiated on a regional level. Therefore, this study assesses the effectiveness of outpatient AF clinics in a collaborative region in the Netherlands.

METHODS

For this study baseline and 6 months follow-up data of a prospective cohort including newly or recently diagnosed AF-patients of 4 hospitals involved in the Netherlands Heart Network are used. From January'15 to March'16 patient relevant outcome measures (ie EHRA score, stroke, major bleedings, hospitalizations, serious adverse effects of medication, and mortality) are gathered. Descriptive and regression analyses are performed to assess the effectiveness of outpatient AF clinics.

RESULTS

In the analyses 448 AF-patients were included. After 6 months, significant improvements regarding EHRA score (P < 0.01), hypertension (P < 0.01), and type of AF (P < 0.01) were indicated. Results of the patient relevant outcomes showed that AF-patients were hospitalized 23 times, no major bleedings and 2 strokes occurred. Furthermore, 0 AF-patients reported serious adverse effects of medication and no AF-patients deceased.

CONCLUSIONS

Collaboration between cardiologists in a regional setting permits further improvement of AF care. Therefore, such quality targets are not exclusively reserved to large academic or referral hospitals. Although promising, future research should put effort in measuring the effectiveness of the outpatient AF clinics also on the long run.

A nurse-coordinated integrated care model to support decision-making and self-care in patients with atrial fibrillation: A study protocol

AIM

This study aims to evaluate the effects of a nurse-coordinated, empowerment-based integrated care model on self-care behaviours and psychosocial outcomes in patients with atrial fibrillation and to explore how this intervention affects patients' self-care behaviours and quality of life.

DESIGN

This mixed-methods study comprises a randomized controlled trial and an exploratory qualitative study.

METHODS

A total of 392 community-dwelling patients aged ≥65 years with a confirmed diagnosis of atrial fibrillation, a high stroke risk and no oral anticoagulants treatment will be recruited from the medical outpatient clinics of a university-affiliated hospital. The patients will be randomly allocated to intervention or control groups, which will receive treatment via the nurse-coordinated integrated care model or standard care, respectively. We hypothesize that compared with patients receiving standard care, atrial fibrillation patients exposed to the nurse-coordinated care model will be more likely to achieve compatible patient and physician decisions regarding the use of oral anticoagulants, better changes in medication adherence, anxiety, depression and health-related quality of life after the intervention. A subsample of 30 participants in the intervention group will also participate in a qualitative interview to provide their views and perceptions about the intervention. The ethical approval has obtained on 5 July 2018. This study is supported by a grant from the Research Grants Council of the Hong Kong Special Administrative Region on 29 June 2018.

DISCUSSION

This study will uniquely adopt an empowerment-based approach to equip patients as active agents in atrial fibrillation management through a nurse-coordinated integrated care model that comprehensively addresses their needs.

IMPACT

Patients with atrial fibrillation are currently receiving inadequate guideline-recommended care. This study will address this important evidence-practice gap by optimizing oral anticoagulant prescription and therapeutic effects and promotes effective patient self-care, so as to achieve worldwide reductions in atrial fibrillation-related morbidity, mortality, and healthcare burdens.

CLINICAL TRIAL REGISTRATION

This study has been registered at ClinicalTrials.gov (NCT03924739).

The impact of nurse-led atrial fibrillation clinics on patient and healthcare outcomes: a systematic mixed studies review

Background:

Atrial fibrillation, the most common arrhythmia worldwide, continues to increase as the population ages. Patients with atrial fibrillation, particularly those newly diagnosed or who have multiple comorbidities, have high healthcare utilisation rates. Nurse-led atrial fibrillation clinics have developed to improve care and guidance for atrial fibrillation patients, with the potential to reduce hospital presentations and healthcare utilisation. Atrial fibrillation clinics that provide specialised and patient-centred care have improved patient symptom management, quality of life and reduced healthcare utilisation and costs.

Aims:

The aim of this study was to provide the first synthesis of evidence for the impact of nurse-led atrial fibrillation clinics on patient, healthcare utilisation, and quality of care outcomes.

Methods:

This systematic mixed studies review examined citations from three databases: Medline, CINAHL and Embase, using the search terms ‘atrial fibrillation’ and ‘clinic’, and related concepts. Seventeen moderate to high quality articles were selected.

Results:

Overall, atrial fibrillation clinics were more cost effective, had shorter wait times and reduced hospitalisation and emergency department visits. Symptoms and sinus rhythm restoration were comparable in the nurse-led compared to physician-led cardioversion clinics. Findings related to patient knowledge and patient satisfaction were mixed, while mortality rates were lower, and patient medication adherence was higher in nurse-led atrial fibrillation compared to usual care. Quality of life and guideline adherence was increased in patients receiving nurse-led atrial fibrillation care compared to usual care.

Conclusion:

Nurse-led clinics improved healthcare, patient and quality care outcomes. Future research might examine the role of technology in delivery of nurse-led clinics in rural/remote areas as well as patient experiences with nurse-led clinics.

Idiopathic atrial fibrillation patients rapidly outgrow their low thromboembolic risk: a 10-year follow-up study

Background

Healthy atrial fibrillation (AF) patients will eventually outgrow their low thromboembolic risk. The purpose of this study is to compare the development of cardiovascular disease in healthy AF patients as compared to healthy sinus rhythm patients and to assess appropriate anticoagulation treatment.

Methods

Forty-one idiopathic paroxysmal AF patients (56 ± 10 years, 66% male) were compared with 45 healthy sinus rhythm patients. Patients were free of hypertension, antihypertensive and antiarrhythmic drugs, diabetes, congestive heart failure, coronary artery or peripheral vascular disease, previous stroke, thyroid, pulmonary and renal disease, and structural abnormalities on echocardiography.

Results

Baseline characteristics and echocardiographic parameters were the same in both groups. During 10.7 ± 1.6 years, cardiovascular disease and all-cause death developed significantly more often in AF patients as compared to controls (63% vs 31%, log rank p < 0.001). Even after the initial 5 years of follow-up, survival curves show divergent patterns (log rank p = 0.006). Mean duration to reach a CHA₂DS₂-VASc score > 1 among AF patients was 5.1 ± 3.0 years. Five of 24 (21%) patients with CHA₂DS₂-VASc > 1 did not receive oral anticoagulation therapy at follow-up. Mean duration of over- or undertreatment with oral anticoagulation in patients with CHA₂DS₂-VASc > 1 was 5 ± 3.0 years.

Conclusion

The majority of recently diagnosed healthy AF patients develop cardiovascular diseases with a consequent change in thromboembolic risk profile within a short time frame. A comprehensive follow-up of this patient category is necessary to avoid over- and undertreatment with anticoagulants.

Augmenting Atrial Fibrillation Care After an Emergency Department Visit: Implementing Telephone Practice

BACKGROUND

Between 2010 and 2012, the Heart Rhythm team in a tertiary care hospital completed a retrospective study that found that atrial fibrillation (AF) care can be episodic and heavily reliant on hospital resources, particularly the emergency department (ED).

PROBLEM

Patients who attend the ED with AF are at high risk of hospital admission.

APPROACH

A nurse practitioner (NP) was added to the Heart Rhythm team to create a program to improve AF care after an ED visit. Telephone practice was one of the many processes created.

OUTCOMES

Findings revealed that 37 of 90 patients presented to the ED with AF prior to telephone contact and 7 of 90 patients did so post-telephone contact (P < .001).

CONCLUSION

Telephone practice led by an NP provides an opportunity to improve assessment and management of patient with AF and offers a promising cost-effective method to reduce ED visits in the AF patient population.
