Disease understanding in patients newly diagnosed with atrial fibrillation

Effects of intensive, targeted education by pharmacists on anticoagulant patients with atrial fibrillation: a multicentre randomized controlled trial from China

AIMS

Many people diagnosed with atrial fibrillation (AF) may lack awareness of AF and anticoagulants. The purpose of this study is to investigate the effects of intensive, targeted education by pharmacists on anticoagulant patients with AF.

METHODS AND RESULTS

Three hundred seventy-six AF patients were randomly assigned to receive standard care or pharmacist education. Follow-up is scheduled after 1, 3, 6, and 12 months. Pharmacists provided intensive education on knowledge deficits revealed by the Jessa Atrial fibrillation Knowledge Questionnaire (JAKQ) during each visit. Patients also completed two questionnaires to assess their medication adherence and satisfaction. Clinical outcomes were recorded during follow-up. Three hundred sixty-one patients completed follow-up. Baseline scores on the JAKQ were similar in the education group (median: 31.3%) and the standard care group (median: 31.3%) (P = 0.911). Over time, the knowledge score of the education group increased significantly (1 month: 68.8%, 3 months: 81.3%; P < 0.001), while there was no significant improvement in the standard care group (1 month: 37.5%, 3 months: 37.5%; P = 0.314). Adherence scores improved significantly over time in the education group (P < 0.001) but not in the standard care group (P = 0.101). Compared with standard care, pharmacist education was associated with a significantly lower risk of bleeding (P = 0.034).

CONCLUSION

Given the knowledge deficiency of AF patients in China, standardized patient education should be a part of their daily care. Pharmacist-led education intervention can significantly improve the disease-related knowledge, medication adherence, and drug treatment satisfaction of AF patients while significantly reducing the risk of bleeding.

Application of Alfalfa App in the management of oral anticoagulation in patients with atrial fibrillation: a multicenter randomized controlled trial

BACKGROUND

In recent years, mobile medical technology has made great progress in chronic disease management, but its application in patients with atrial fibrillation (AF) still needs to be clarified.

OBJECTIVE

This study aims to determine whether the newly developed smartphone app for patients with AF (Alfalfa App) can improve anticoagulation knowledge, drug treatment compliance, and satisfaction of AF patients.

METHODS

Alfalfa App integrates the functions of patient education, remote consultation, and medication reminder through a simple user interface. From June 2020 to December 2020, patients with AF were recruited in five large tertiary hospitals in China. Patients were randomly divided into the Alfalfa App or routine nursing groups. Patients' knowledge, medication adherence, and satisfaction with anticoagulation were assessed using validated questionnaires at baseline, 1 month, and 3 months.

RESULTS

In this randomized controlled trial, 113 patients with AF were included, 57 patients were randomly assigned to the Alfalfa App group, and 56 patients were randomly assigned to the routine nursing group. Forty-eight patients in the Alfalfa App group completed a three-month follow-up, and 48 patients in the routine nursing group completed a three-month follow-up. Basic demographic data were comparable between the two groups. The average age of AF patients was 61.65 ± 11.01 years old, and 61.5% of them were male. With time (baseline to 3 months), the knowledge scores of the Alfalfa App group (P<.001) and the routine nursing group (P = .002) were significantly improved, the compliance scores of the routine nursing group(P<.001) and Alfalfa App group(P<.001) significantly improved. Compared with the routine nursing group, patients' knowledge level and medication compliance using the Alfalfa App at 1 month and 3 months were significantly higher (all P < .05). There were significant differences in knowledge and compliance scores between the two groups with time (all P < .05). The satisfaction degree of drug treatment in the Alfalfa App group was significantly better than that in the routine nursing group (all P < .05).

CONCLUSIONS

Alfalfa App significantly improved the anticoagulation knowledge, drug treatment compliance, and satisfaction of AF patients. In oral anticoagulation management for AF patients, mobile medical technology that integrates the functions of patient education, remote consultation, and medication reminder may be helpful.

Knowledge, attitude and practice toward oral anticoagulants among patients with atrial fibrillation

Background

Atrial fibrillation (AF) is a common cardiac arrhythmia that increases the risk of stroke and other cardiovascular complications. Oral anticoagulants (OACs) are effective in reducing this risk. To investigate the knowledge, attitude and practice (KAP) toward OACs among patients with AF.

Methods

This web-based cross-sectional study was conducted at local Hospital between April 2023 and May 2023, and enrolled AF patients.

Results

A total of 491 valid questionnaires were collected, with 293 (59.67%) male and 73.93% resided in urban areas. The KAP scores were 4.64 ± 3.28, 21.09 ± 2.33 and 26.18 ± 2.15, respectively. Multivariate logistic regression analysis showed that junior high school [odd ratio (OR) = 0.346, 95% confidence interval (CI) = 0.145-0.825, P = 0.017], junior college/bachelor and above (OR = 6.545, 95% CI = 2.863-14.963, P < 0.001), monthly income ≥5,000 (OR = 2.343, 95% CI = 1.074-5.111, P = 0.032), never taken OACs (OR = 0.015, 95% CI = 0.004-0.059, P < 0.001), and having been diagnosed AF (6-10 months, OR = 4.003, 95% CI = 1.653-9.692, P = 0.002;over 20 months, OR = 4.046, 95% CI = 1.753-9.340, P = 0.001) were independently associated with knowledge. Knowledge (OR = 1.376, 95% CI = 1.162-1.629, P < 0.001), junior high school (OR = 0.258, 95% CI = 0.084-0.792, P = 0.018), monthly income ≥5,000 (OR = 5.486, 95% CI = 1.834-16.412, P = 0.002), and never undergone AF ablation (OR = 0.214, 95% CI = 0.097-0.471, P < 0.001) were independently associated with attitude. Knowledge (OR = 1.128, 95% CI = 1.030-1.235, P = 0.009), 70-79 years (OR = 2.193, 95% CI = 1.166-4.124, P = 0.015) and ≥80 years (OR = 4.375, 95% CI = 2.034-9.411, P < 0.001) were independently associated with proactive practice.

Conclusion

Patients with AF had inadequate knowledge, suboptimal attitude and inactive practice towards AF and OACs. Improving patient education, especially among those with lower education levels, enhances understanding and management of AF and OACs.

Assessment of the general public's knowledge of atrial fibrillation through social media: a cross-sectional study

BACKGROUND

Early detection and timely treatment of atrial fibrillation (AF) remains pivotal to preventing AF-related complications. Public involvement in recognising potential AF symptoms and managing AF is vital for early detection and treatment of AF.

OBJECTIVE

The aim of the study is to assess the general public's knowledge of AF using an online survey, disseminated via social media.

METHODS

A cross-sectional online survey of the general public was conducted between November to December 2021. The survey's URL was shared on National University Heart Centre, Singapore's official Facebook page. Digital marketing strategies were employed to recruit members of the public. The 27-item survey assessed public's knowledge across five domains: basic information about AF, risk factors of AF, detection of AF, prevention of AF, and management of AF.

RESULTS

The survey involved 620 participants. Approximately two-thirds were between the ages 21 to 40 years (64.5%), female (60%) and had at least a degree (64.7%) as their highest level of education. Participants obtained a mean percentage score of 63.3 ± 26.0 for their AF knowledge. One-way ANOVA was done to examine the associations between the participants' characteristics and their knowledge of AF. There were no statistically significant differences in the AF knowledge scores across the various sociodemographic subgroups.

CONCLUSIONS

Members of the public recruited from Facebook and via digital marketing had moderately good knowledge of AF. However, public awareness pertaining to preventing AF has potential for improvement. The utility of social media in reaching the general public was illustrated through this study.

The information needs of patients with atrial fibrillation: A scoping review

AIMS AND OBJECTIVES

To identify the atrial fibrillation (AF)-specific information needs of patients with AF.

BACKGROUND

Patients' understanding of AF is pertinent to optimising treatment and outcomes, thus highlighting the need for effective patient education. The information required to deliver effective AF-specific patient education is less examined.

METHODS

Guided by Arksey and O'Malley's framework, a scoping review was conducted for studies reporting the AF-specific information needs of patients with AF. Systematic searches were conducted across six databases (Medline, PubMed, CINAHL, Scopus, PsycINFO and ProQuest). All analyses were narrated in prose and outlined in tables. The PRISMA-ScR checklist was used to report this review.

RESULTS

The systematic search yielded 3816 articles, of which 22 were included. Three major themes emerged from the thematic analysis. Each theme was supported by three subthemes. First, in 'Understanding AF', patients reported the need for 'Easy-to-understand information', information on the 'Screening and diagnosis' of AF and 'Trajectory of disease and its associated risks'. Second, in 'Treating AF', patients required information on the 'Role of anticoagulation', 'Existing or novel therapeutic options' and 'Monitoring effectiveness of treatment'. Lastly, in 'Living with AF', patients needed education in 'Symptom management', 'Secondary prevention of risks' and 'Recognition of emergency situations'.

CONCLUSIONS

This review has identified the key AF-specific information needs of patients with AF. Being cognisant of the information needs of patients with AF, healthcare providers may become more effective in developing person-centred patient education interventions.

RELEVANCE TO CLINICAL PRACTICE

Delivering relevant patient education is an important cornerstone for atrial fibrillation care. Nurses by convention play a professional role in patient education. It may be facilitative for nurses to refer to the review findings when developing and implementing patient education interventions. Being in the midst of an ongoing pandemic, patient education strategies may require the use of telecommunication technologies.

Reasons for Nonadherence to the Direct Oral Anticoagulant Apixaban: A Cross-Sectional Survey of Atrial Fibrillation Patients

Background

Nonadherence to direct oral anticoagulants to prevent stroke occurs in up to 40% of atrial fibrillation patients. Underlying reasons are poorly understood.

Objectives

This study quantified patient-reported reasons for nonadherence and identified strategies to improve adherence.

Methods

This is a cross-sectional survey of atrial fibrillation patients in 2 academic health systems who reported apixaban nonadherence. We examined patient-reported reasons for nonadherence and level of nonadherence (assessed by a validated 3-item adherence measure) using a multivariable logistic regression model.

Results

Of 419 study patients, 41.5% were women. The mean age was 71.1 ± 10 years and mean CHA2DS2VASc score was 3.2 ± 1.6. About two-thirds had adherence scores ≥80 (mild nonadherence) and one-third scores <80 (poor adherence). In all groups, forgetfulness contributed to nonadherence. Attitudes/beliefs associated with adherence score <80 included: not believing apixaban was needed (odds ratio [OR]: 12.24 [95% CI: 2.25-66.47]); medication cost (OR: 3.97 [95% CI: 1.67-9.42]); and fear of severe bleeding (OR: 3.28 [95% CI: 1.20-8.96]). Strategies that patients with adherence scores <80 selected as helping "a great deal/a lot" to increase adherence included bloodwork to evaluate efficacy (56%), physician counseling about adherence (55%), and having a reversal agent (39%). Almost one-half of all patients did not disclose nonadherence to their providers.

Conclusions

Patients may not disclose their nonadherence to prescribers, and attitudes related to apixaban nonadherence differ among patients with mild nonadherence versus poor adherence. While all patients may benefit from strategies to address forgetfulness, concerns related to the purpose of apixaban, cost, and bleeding risk may require special attention in those with poor adherence.

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.

Why do people take part in atrial fibrillation screening? Qualitative interview study in English primary care

OBJECTIVES

There is insufficient evidence to support national screening programmes for atrial fibrillation (AF). Nevertheless, some practitioners, policy-makers and special interest groups have encouraged introduction of opportunistic screening in primary care in order to reduce the incidence of stroke through earlier detection and treatment of AF. The attitudes of the public towards AF screening are unknown. We aimed to explore why AF screening participants took part in the screening.

DESIGN

Semistructured longitudinal interview study of participant engagement in the SAFER study (Screening for Atrial Fibrillation with ECG to Reduce stroke). We undertook initial interviews face to face, with up to two follow-up telephone interviews during the screening process. We thematically analysed and synthesised these data to understand shared views of screening participation.

SETTING

5 primary care practices in the East of England, UK.

PARTICIPANTS

23 people taking part in the SAFER study first feasibility phase.

RESULTS

Participants were supportive of screening for AF, explaining their participation in screening as a 'good thing to do'. Participants suggested screening could facilitate earlier diagnosis, more effective treatment, and a better future outcome, despite most being unfamiliar with AF. Participating in AF screening helped attenuate participants' concerns about stroke and demonstrated their commitment to self-care and being a 'good patient'. Participants felt that the screening test was non-invasive, and they were unlikely to have AF; they therefore considered engaging in AF screening was low risk, with few perceived harms.

CONCLUSIONS

Participants assessed the SAFER AF screening programme to be a legitimate, relevant and safe screening opportunity, and complied obediently with what they perceived to be a recommendation to take part. Their unreserved acceptance of screening benefit and lack of awareness of potential harms suggests that uptake would be high but reinforces the importance of ensuring participants receive balanced information about AF screening initiatives.

Measurement of patient confidence in self-management of atrial fibrillation: Initial validation of the Confidence in Atrial fibriLlation Management (CALM) Scale

BACKGROUND

The patient experience of atrial fibrillation (AF) involves several daily self-care behaviors and ongoing confidence to manage their condition. Currently, no standardized self-report measure of AF patient confidence exists. The purpose of this study is to provide preliminary support for the reliability and validity of a newly developed confidence in AF management measure.

METHODS

This study provides preliminary analysis of the Confidence in Atrial FibriLlation Management (CALM) scale, which was rationally developed to measure patient confidence related to self-management of AF. The scale was provided to a sample of AF patients N = 120, (59% male) electronically through a patient education platform. Principal component analysis (PCA) and Cronbach's α were employed to provide preliminary assessment of the validity and reliability of the measure.

RESULTS

PCA identified a four-factor solution. Internal consistency of the CALM was considered excellent with Cronbach's α = .910. Additional PCA confirmed the value of a single factor solution to produce a total confidence score for improved utility and ease of clinical interpretation.

CONCLUSIONS

Initial assessment of a novel scale measuring patient confidence in managing AF provided promising reliability and validity. Patient confidence in self-management of AF may prove useful as a key marker and endpoint of the patient experience beyond QOL.

Effect of a virtual self-management intervention for atrial fibrillation during the outbreak of COVID-19

BACKGROUND

As the pandemic continues to unfold, effective, technology-based solutions are needed to help patients with atrial fibrillation (AF) maintain their health and well-being during the outbreak of COVID-19.

METHODS

This single-center, pilot study investigated the effects of a 4-week (eight sessions) virtual AF self-management program. Questionnaires were completed at baseline and 1 week after the intervention, and assessed AF knowledge, adherence to self-management behaviors, mental health, physical function, and disease-specific quality of life in patients with AF. Secondary outcomes included knowledge of COVID-19, intervention, acceptability, and satisfaction.

RESULTS

Of 68 patients who completed baseline questionnaires, 57 participated in the intervention and were included in the analysis (mean age of 73.4 ± 10.0 years, 60% male). Adherence to AF self-monitoring behaviors, including monitoring their heart rate (p < .001), heart rhythm (p = .003), and blood pressure (p = .013) were significantly improved at the end of the intervention compared with baseline. Symptom identification (p = .007) and management (p < .001) also improved. Reductions in sleep disturbance (p < .001), anxiety (p = .014), and depression (p = .046) were also observed. Misinformation and inaccurate beliefs about COVID-19 were significantly reduced at the end of the intervention compared with baseline.

CONCLUSIONS

This pilot study suggests that a virtual patient education program could have beneficial effects on adherence to guideline-recommend self-care of AF, emotional wellbeing, physical function, and knowledge of COVID-19 in patients with AF. Future randomized studies in larger samples are needed to determine the clinical benefits of the intervention.

Virtual reality informative aids increase residents' atrial fibrillation ablation procedures-related knowledge and patients' satisfaction

BACKGROUND

Atrial fibrillation (AF) is the most common cardiac arrhythmia, and increasing numbers of patients receive AF ablation nowadays. Therefore, in the cardiology division, residents need to be familiar with the AF ablation procedure-related knowledge for primary care. This study evaluated the baseline residents and patients' self-efficacy to the AF ablation procedure-related knowledge, developed the specific virtual reality (VR) informative aids, and evaluated the effects of VR training and resident-led VR aids-based patient education on their self-efficacy, in the aspects of familiarity, confidence and anxiety, and satisfaction.

METHODS

From 2019, April to 2020, April, this 1-year prospective prestudy and poststudy was undergone in the cardiology division. Between 2019, April and 2019, December, the experienced physicians were invited to develop VR informative aids for AF ablation procedure-related knowledge. Between January 2020 and April 2020, newly developed VR informative aids were implemented in the educational program of training rotated residents for giving patient education.

RESULT

A total of 20 residents and 32 patients were enrolled. The baseline self-reported self-efficacy and knowledge scores were relatively low among rotated residents and their patients. In addition to the high level of satisfaction, self-efficacy and knowledge scores of residents and their patients were increased after VR aids-based training and resident-led patient education. Higher degree of improvement in self-efficacy was noted among patients with depression/anxiety history than those without history. The follow-up assessments among residents showed that the positive effects of VR aids were sustained until 2 weeks later.

CONCLUSION

Overall, residents and patients reported that the VR aids increase the effectiveness of patient education, achieve the purpose of a paperless environment, and motivate them to recommend it to others. The implementation of resident-to-patient education has a positive impact on trainees and patients understanding about AF ablation procedures-related knowledge.

An Analysis of Perceived and Actual Anticoagulant Knowledge among Independent Pharmacy Patients

Background:

Deficits in knowledge of parameters surrounding anticoagulant therapy administration carry substantial risks for patient harm. Patients prescribed anticoagulants may overestimate their knowledge of anticoagulant use principles. The purpose of this study was to analyze independent pharmacy patients’ perceived versus actual knowledge of their anticoagulation therapies.

Methods:

A 15-item survey across a dual-site pharmacy location evaluated patients’ confidence in their understanding of anticoagulant prescribing parameters and their awareness of measures to take to safeguard anticoagulant therapy routines. A pharmacist reviewed patient responses to survey items referencing actual understanding of anticoagulant therapies at the conclusion of the survey. Data analyses occurred by gender, age, ethnicity, location, living situation, self-management of anticoagulants, patient perception of anticoagulant safety, and reported receipt of anticoagulant education. Linear regressions were used for statistical analyses, with significance set at p<.05.

Results:

During the span of three months, 45 patients, 20 females and 25 males, completed the survey. Perceived anticoagulant knowledge did not differ significantly by demographics. Actual anticoagulant knowledge declined by over 20% between age groups 60-69 and 80-89 years old. African Americans displayed 10% lower actual anticoagulant knowledge than Caucasian Americans.

Conclusions:

This study revealed gaps in knowledge of anticoagulants among patients at an independent pharmacy. An appeal remains for more strategies to assist with knowledge of anticoagulant regimens. Healthcare institutions should continue to incorporate programs geared towards ongoing anticoagulant education, such as question and answer sessions, along with peer support mediums that foster optimal outcomes.

Perspectives of Patients and Professionals on Information and Education After Myocardial Infarction With Insight for Mixed Reality Implementation: Cross-Sectional Interview Study

BACKGROUND

Patient education is crucial in the secondary prevention of cardiovascular disease. Novel technologies such as augmented reality or mixed reality expand the possibilities for providing visual support in this process. Mixed reality creates interactive digital three-dimensional (3D) projections overlaying virtual objects on the real-world environment. While augmented reality only overlays objects, mixed reality not just overlays but anchors virtual objects to the real world. However, research on this technology in the patient domain is scarce.

OBJECTIVE

The aim of this study was to understand how patients perceive information provided after myocardial infarction and examine if mixed reality can be supportive in this process.

METHODS

In total, 12 patients that experienced myocardial infarction and 6 health care professionals were enrolled in the study. Clinical, demographic, and qualitative data were obtained through semistructured interviews, with a main focus on patient experiences within the hospital and the knowledge they gained about their disease. These data were then used to map a susceptible timeframe to identify how mixed reality can contribute to patient information and education.

RESULTS

Knowledge transfer after myocardial infarction was perceived by patients as too extensive, not personal, and inconsistent. Notably, knowledge on anatomy and medication was minimal and was not recognized as crucial by patients, whereas professionals stated the opposite. Patient journey analysis indicated the following four critical phases of knowledge transfer: at hospital discharge, at the first outpatient visit, during rehabilitation, and during all follow-up outpatient visits. Important patient goals were understanding the event in relation to daily life and its implications on resuming daily life. During follow-up, understanding physical limitations and coping with the condition and medication side effects in daily life emerged as the most important patient goals. The professionals' goals were to improve recovery, enhance medication adherence, and offer coping support.

CONCLUSIONS

There is a remarkable difference between patients' and professionals' goals regarding information and education after myocardial infarction. Mixed reality may be a practical tool to unite perspectives of patients and professionals on the disease in a more even manner, and thus optimize knowledge transfer after myocardial infarction. Improving medication knowledge seems to be a feasible target for mixed reality. However, further research is needed to create durable methods for education on medication through mixed reality interventions.

Evaluation of a program of pharmaceutical counseling for French patients on oral anticoagulant therapy

Background Oral anticoagulants are widely used for treatment and prevention of thromboembolic diseases. We set up a pharmaceutical counseling program for both direct oral anticoagulant and vitamin K antagonist drugs in our hospital in 2015. Objective Evaluate patient satisfaction and the evolution of their knowledge throughout the pharmaceutical counseling program on anticoagulants and identify knowledge variability factors. Setting Cardiology Inpatient Unit from the University Antoine Béclère Hospital, France. Methods Evaluation was based on data collection of patients surveyed between 2015 and 2018. Inpatients in the cardiology department on oral anticoagulants were eligible. The learning process was designed to enhance patient knowledge and understanding based on 10 cognitive or self-management skills, relating to the optimization of oral anticoagulant therapy management. It consisted in 2 face-to-face interviews during hospitalization and 2 additional phone interviews one and six months after discharge. The median patient score was evaluated at each step of the process as well as the mean score for each item from the global population. A sub-analysis was run on the less well-acquired skills in order to identify risk factors for limited knowledge. The association between those factors and the level of knowledge (score ≥ 7 or < 7) was assessed using Chi square test followed by multivariate analysis. Main outcome measure Patient knowledge of anticoagulation therapy depending on specific factors. Results Of the 880 patients eligible for pharmaceutical counseling, 319 entered the process and 102 completed it. Median knowledge scores were 8/10 and 9/10 after the first and the final interviews respectively with a significant improvement (p = 0.0003). The least well-acquired items at each step were surveillance and under-dosing management. The sub-analysis showed the use of vitamin K antagonist to be linked to an enhanced understanding related to treatment surveillance (p = 0.029). Patients suffering from atrial fibrillation were found to have a worse understanding of under-dosing management (p = 0.013). Finally, patients evaluated the process as helpful and suitable for their conditions. Conclusion Pharmaceutical counseling is appropriate for patients, improving and maintaining knowledge of oral anticoagulants. Our evaluation highlights the need to focus on patient-specific profiles to reach a satisfactory level of knowledge.

Perception of the Risk of Stroke and the Risks and Benefits of Oral Anticoagulation for Stroke Prevention in Patients With Atrial Fibrillation: A Cross-Sectional Study

OBJECTIVE

To assess the perception of the risk of stroke and the risks and benefits of oral anticoagulation (OAC) in patients with atrial fibrillation (AF).

PATIENTS AND METHODS

Consecutive patients with chronic AF who presented for an outpatient cardiology visit or were admitted to a noncritical care cardiology ward service from September 15 through December 20, 2017, were invited to participate in this survey. Participants were asked to estimate their stroke risk without OAC and bleeding risk with OAC using a quantitative risk scale. The reported values were compared with subjectively estimated risks derived from the CHA₂DS₂-VASc and HAS-BLED scores. Similarly, we compared patient perception of the stroke risk reduction afforded with OAC compared with what is reported in the literature.

RESULTS

A total of 227 patients were included in the analysis. The mean ± SD CHA₂DS₂-VASc score was 4.3±1.6, and HAS-BLED score was 2.3±1.2. Atrial fibrillation was paroxysmal in 53.3% and persistent/permanent in 46.7%. There was a negligible correlation between patient perceived and estimated risk of stroke (r=0.07; P=.32), and bleeding (r=0.16; P=.02). Most patients overestimated their risks of stroke and bleeding: 120 patients (52.9%) perceived an annual stroke risk greater than 20%, and 115 (53.5%) perceived an annual bleeding risk with OAC greater than 10%. Most patients (n=204; 89.9%) perceived that OAC would reduce their annual stroke risk by at least 50%.

CONCLUSION

Perceived risks of stroke and bleeding are markedly overestimated in most patients with AF. Further research is needed to discern the root causes and to identify effective methods of bridging this alarming disparity.

International longitudinal registry of patients with atrial fibrillation and treated with rivaroxaban: RIVaroxaban Evaluation in Real life setting (RIVER)

Background

Real-world data on non-vitamin K oral anticoagulants (NOACs) are essential in determining whether evidence from randomised controlled clinical trials translate into meaningful clinical benefits for patients in everyday practice. RIVER (RIVaroxaban Evaluation in Real life setting) is an ongoing international, prospective registry of patients with newly diagnosed non-valvular atrial fibrillation (NVAF) and at least one investigator-determined risk factor for stroke who received rivaroxaban as an initial treatment for the prevention of thromboembolic stroke. The aim of this paper is to describe the design of the RIVER registry and baseline characteristics of patients with newly diagnosed NVAF who received rivaroxaban as an initial treatment.

Methods and results

Between January 2014 and June 2017, RIVER investigators recruited 5072 patients at 309 centres in 17 countries. The aim was to enroll consecutive patients at sites where rivaroxaban was already routinely prescribed for stroke prevention. Each patient is being followed up prospectively for a minimum of 2-years. The registry will capture data on the rate and nature of all thromboembolic events (stroke / systemic embolism), bleeding complications, all-cause mortality and other major cardiovascular events as they occur. Data quality is assured through a combination of remote electronic monitoring and onsite monitoring (including source data verification in 10% of cases). Patients were mostly enrolled by cardiologists (n = 3776, 74.6%), by internal medicine specialists 14.2% (n = 718) and by primary care/general practice physicians 8.2% (n = 417). The mean (SD) age of the population was 69.5 (11.0) years, 44.3% were women. Mean (SD) CHADS₂ score was 1.9 (1.2) and CHA₂DS₂-VASc scores was 3.2 (1.6). Almost all patients (98.5%) were prescribed with once daily dose of rivaroxaban, most commonly 20 mg (76.5%) and 15 mg (20.0%) as their initial treatment; 17.9% of patients received concomitant antiplatelet therapy. Most patients enrolled in RIVER met the recommended threshold for AC therapy (86.6% for 2012 ESC Guidelines, and 79.8% of patients according to 2016 ESC Guidelines).

Conclusions

The RIVER prospective registry will expand our knowledge of how rivaroxaban is prescribed in everyday practice and whether evidence from clinical trials can be translated to the broader cross-section of patients in the real world.

Effect of reinforced, targeted in-person education using the Jessa Atrial fibrillation Knowledge Questionnaire in patients with atrial fibrillation: A randomized controlled trial

BACKGROUND

The knowledge level of atrial fibrillation patients about their arrhythmia, its consequences and treatment is poor. The best strategy to provide education is unknown.

AIM

To investigate the effect of reinforced targeted in-person education using the Jessa Atrial fibrillation Knowledge Questionnaire (JAKQ).

METHODS

Sixty-seven atrial fibrillation patients were randomized to standard care (including brochures) or targeted education. Follow-up visits were scheduled after one, three, six and 12 months. Targeted education during each visit focused on the knowledge gaps revealed by the JAKQ. Patients completed two questionnaires to assess their quality of life and symptom profile. Adherence to non-vitamin K antagonist oral anticoagulants was measured using electronic monitoring.

RESULTS

Sixty-two patients (31 education; 31 standard care) completed follow-up. Median baseline score on the JAKQ was similar in education (62.5%) and standard care group (56.3%; p=0.815). The intervention group scored significantly better over time (one month: 75.0%, 12 months: 87.5%; p<0.001) whereas there was no significant improvement in the control group (one month: 62.5%, 12 months: 62.5%; p=0.085). Providing targeted education after completion of the JAKQ required on average 6.9±4.6 min. Some improvements in quality of life, symptom burden and adherence were shown, without significant differences between the two groups ( p-values between 0.282 and 0.677).

CONCLUSION

The JAKQ is an effective tool for providing individualized education. A first targeted educational session significantly improved patients' knowledge level. Additional educational sessions maintained and strengthened this effect. A larger scale study is warranted to evaluate the impact on adherence and outcome measures.
