Adherence to direct or vitamin K antagonist oral anticoagulants in patients with atrial fibrillation: a long-term observational study.

Our objectives were to measure long-term adherence to oral anticoagulants (OACs) in patients with atrial fibrillation (AF) and to identify patient factors associated with adherence. Using linked, population-based administrative data from British Columbia, Canada, an incident cohort of adults prescribed OACs for AF was identified. We calculated the proportion of days covered (PDC) as a time-dependent covariate for each 90-day window from OAC initiation until the end of follow-up. Associations between patient attributes and adherence were assessed using generalized mixed effect linear regression models. 30,264 patients were included. Mean PDC was 0.69 (SD 0.28) over a median follow-up of 6.7 years. 54% of patients were non-adherent (PDC < 0.8). After controlling for confounders, factors positively associated with adherence were number of drug class switches, history of stroke or transient ischemic attack, history of vascular disease, time since initiation, and age. Age > 75 years at initiation, polypharmacy (among VKA users only), and receiving DOAC (vs. VKA) were negatively associated with adherence. PDC decreased over time for VKA users and increased for DOAC users. Over half of AF patients studied were, on average, nonadherent to OAC therapy and missed 32% of their doses. Several patient factors were associated with higher or lower adherence, and adherence to VKA declined during therapy while DOAC adherence increased slightly over time. To min im ize the risk stroke, adherence-supporting interventions are needed for all patients with AF, particularly those aged > 75 years, those with prior stroke or vascular disease, VKA users with polypharmacy, and DOAC recipients.

Sodium-glucose cotransporter 2 inhibitors and the risk of venous thromboembolism: A population-based cohort study.

AIMS: The cardiovascular benefits of sodium-glucose cotransporter 2 inhibitors (SGLT2Is) result from their complex impact on coronary and arterial vessels. However, their effect on veins and the risk of venous thromboembolism (VTE) remains unclear. Meta-analysis of trials has suggested no significant change in risk, but observational studies on the topic are scarce. Our objective was to determine if the use of SGLT2Is, compared to the use of dipeptidyl peptidase 4 inhibitors (DPP-4Is), is associated with the risk of VTE among patients with type 2 diabetes. METHODS: Using the Clinical Practice Research Datalink linked to hospitalization and vital statistics databases, we conducted a retrospective cohort study using a prevalent new-user design. SGLT2Is were matched to DPP-4I users on calendar time, diabetes treatment intensity, duration of previous DPP-4I use and time-conditional high-dimensional propensity score. Cox proportional hazard models estimated the hazard ratio (HR) for VTE with SGLT2Is versus DPP-4Is. RESULTS: SGLT2I use was not associated with an increased risk of VTE (HR 0.65, 95% confidence interval [CI] 0.34 to 1.25). This finding was consistent among prevalent (HR 0.47, 95% CI 0.16 to 1.42) and incident (HR 0.75, 95% CI 0.33 to 1.72) new users. CONCLUSIONS: We found that SGLT2Is were not associated with an increased risk of VTE compared to DPP-4Is. Although we observed a numerically decreased risk of VTE with SGLT2Is, estimates were accompanied by wide 95% CIs. Nonetheless, given the morbidity associated with VTE, our results provide some reassurance regarding the safety of SGLT2Is with respect to VTE.

Oral anticoagulant adherence and switching in patients with atrial fibrillation: A prospective observational study.

BACKGROUND: Adherence to oral anticoagulants (OACs) in patients with atrial fibrillation (AF) is important in preventing stroke. The dominance of retrospective studies using administrative data has led to a lack of data on psychosocial determinants of adherence and prevented comparison of adherence between OAC drug classes. OAC switching is another aspect of adherence that is unexplored. METHODS: A prospective design was utilized to measure AF patients' self-reported adherence and OAC switching, and to identify their clinical, demographic, and psychosocial determinants. Participants were recruited from specialized AF clinics in Canada and followed for up to 2 years. Data were collected via telephone every 3-4 months using a structured survey. Adherence was measured using the Morisky Medication Adherence scale (©MMAS-8). RESULTS: The included participants (N = 306) were followed for a median follow up time of 14.1 months and had an average of 3.2(SD 1.4) study visits. The mean self-reported adherence on the ©MMAS-8 was 7.28(SD 0.71) for patients receiving care at specialized AF clinics. Older age, experiencing a bleed, and higher satisfaction with the burden of medications were significantly associated with higher adherence. Drug class did not have any significant impact on adherence. 7.8% of the cohort experienced a switch with most of them being from warfarin to DOAC. Taking warfarin as the index medication, experiencing a bleed and older age were significantly associated with higher odds of switching. CONCLUSION: Patients with AF reported high adherence to their OAC therapy however being on DOAC may not translate to better adherence compared to VKA. Improving satisfaction with the burden of therapy is important in improving adherence.

The Random Effects Warfarin Days' Supply (REWarDS) Model: Development and Validation of a Novel Method for Estimating Exposure to Warfarin Using Administrative Data.

Warfarin's complex dosing is a significant barrier to measurement of its exposure in observational studies using population databases. Using population-based administrative data (1996-2019) from British Columbia, Canada, we developed a method based on statistical modeling (Random Effects Warfarin Days' Supply (REWarDS)) that involves fitting a random-effects linear regression model to patients' cumulative dosage over time for estimation of warfarin exposure. Model parameters included a minimal universally available set of variables from prescription records for estimation of patients' individualized average daily doses of warfarin. REWarDS estimates were validated against a reference standard (manual calculation of the daily dose using the free-text administration instructions entered by the dispensing pharmacist) and compared with alternative methods (fixed window, fixed tablet, defined daily dose, and reverse wait time distribution) using Pearson's correlation coefficient (r), the intraclass correlation coefficient, and the root mean squared error. REWarDS-estimated days' supply showed strong correlation and agreement with the reference standard (r = 0.90 (95% confidence interval (CI): 0.90, 0.90); intraclass correlation coefficient = 0.95 (95% CI: 0.94, 0.95); root mean squared error = 8.24 days) and performed better than all of the alternative methods. REWarDS-estimated days' supply was valid and more accurate than estimates from all other available methods. REWarDS is expected to confer optimal precision in studies measuring warfarin exposure using administrative data.

Satisfaction With Oral Anticoagulants Among Patients With Atrial Fibrillation: A Prospective Observational Study.

BACKGROUND: Satisfaction with treatment has been identified as an important contributing factor to adherence with oral anticoagulant (OAC) therapy in patients with atrial fibrillation (AF). We aimed to evaluate the satisfaction level of patients with AF regarding OAC use over time, using validated patient-reported outcome instruments, and to identify associated patient characteristics. METHODS: Participants were recruited from specialized AF clinics in Canada. Eligible AF patients who were prescribed OACs were followed for up to 2 years. Participants were interviewed via telephone every 3-4 months using a structured survey. The Treatment Satisfaction Questionnaire for Medication (TSQM II) and the Anti-Clot Treatment Scale (ACTS) were used to measure satisfaction over time. RESULTS: Among the 306 participants, satisfaction scores on the TSQM II and ACTS instruments were high. Unadjusted analyses showed significantly greater satisfaction with the burden of therapy with direct OACs (DOACs) compared to that with warfarin (small-magnitude effect) and greater satisfaction with the convenience of rivaroxaban, compared with that of all other OACs (moderate-magnitude effect). After adjustment for all other variables, vitamin K antagonist therapy was associated with greater global satisfaction than was DOAC treatment. Satisfaction with benefit and burden as measured by the ACTS scale, and global satisfaction on the TSQM II scale, tended to increase over time. Patient factors that were somewhat consistently associated with greater satisfaction were female sex and younger age. CONCLUSIONS: Patients with AF were highly satisfied with their therapy, with few differences among OAC classes and individual OACs. Individual patients may or may not be more satisfied with DOAC than VKA therapy, and regardless of the OAC prescribed, the may require significant support to maintain therapy adherence.

CONTEXTE: La satisfaction à l'égard du traitement a été désignée comme un facteur important contribuant à l'adhésion au traitement par anticoagulants oraux (ACO) chez les patients atteints de fibrillation auriculaire (FA). Notre objectif était d'évaluer le degré de satisfaction des patients atteints de FA concernant l'utilisation des ACO au fil du temps, à l'aide d'instruments validés mesurant les résultats signalés par les patients, et de déterminer les caractéristiques connexes des patients. MÉTHODOLOGIE: Les participants ont été recrutés dans des cliniques spécialisées en FA au Canada. Les patients admissibles atteints de FA qui se sont fait prescrire des ACO ont été suivis pendant une période allant jusqu'à 2 ans. Les participants ont été interrogés par téléphone tous les 3 ou 4 mois à l'aide d'une enquête structurée. Le questionnaire Treatment Satisfaction Questionnaire for Medication ­ Version II (TSQM II) et l'échelle Anti-Clot Treatment Scale (ACTS) ont été utilisés pour mesurer la satisfaction au fil du temps. RÉSULTATS: Parmi les 306 participants, les taux de satisfaction indiqués par les instruments TSQM II et ACTS étaient élevés. Les analyses non corrigées ont montré une satisfaction liée au fardeau du traitement significativement plus élevée avec les ACO directs qu'avec la warfarine (effet de faible ampleur) et une plus grande satisfaction concernant la commodité du rivaroxaban par rapport à celle de tous les autres ACO (effet de moyenne ampleur). Après ajustement pour tenir compte de toutes les autres variables, le traitement par antivitamines K (AVK) était associé à une plus grande satisfaction globale que le traitement par ACO direct. La satisfaction à l'égard des avantages et du fardeau, mesurée par l'échelle ACTS, et la satisfaction globale sur l'échelle TSQM II, ont eu tendance à augmenter avec le temps. Les facteurs liés aux patients qui ont été associés de manière assez constante à une plus grande satisfaction étaient le sexe féminin et un âge plus jeune. CONCLUSIONS: Les patients atteints de FA étaient très satisfaits de leur traitement, et peu de différences existaient entre les classes d'ACO et les ACO individuels. Chaque patient peut être ou non plus satisfait du traitement par ACO direct que par AVK et, quel que soit l'ACO prescrit, il peut avoir besoin d'un soutien important pour maintenir l'adhésion au traitement.

Longitudinal Oral Anticoagulant Adherence Trajectories in Patients With Atrial Fibrillation.

BACKGROUND: Conventional adherence summary measures do not capture the dynamic nature of adherence. OBJECTIVES: This study aims to characterize distinct long-term oral anticoagulant adherence trajectories and the factors associated with them in patients with atrial fibrillation. METHODS: Adults with incident atrial fibrillation were identified using linked population-based administrative health data in British Columbia, Canada (1996-2019). Group-based trajectory modeling was used to model patients' 90-day proportions of days covered over time to identify distinct 5-year adherence trajectories. Multinomial regression analysis was used to assess the effect of various demographic and clinical factors on exhibiting each adherence trajectory. RESULTS: The study cohort included 19,749 patients with AF (mean age: 70.6 ± 10.6 years), 56% male, mean CHA2DS2-VASc stroke risk score 2.8 ± 1.4. Group-based trajectory modeling identified 4 distinct oral anticoagulants adherence trajectories: "consistent adherence" (n = 14,631, 74% of the cohort), "rapid decline and discontinuation" (n = 2,327, 12%), "rapid decline and partial recovery" (n = 1,973, 10%), and "slow decline and discontinuation" (n = 819, 4%). Very few patient variables were found to be associated with specific adherence trajectories. CONCLUSIONS: There is heterogeneity among nonadherent patients in the rate and timing of decline in their medication taking. Clinical and demographic characteristics were found to be inadequate to predict patients' adherence trajectories. Insights from this study could be used to inform the design and timing of adherence interventions, and qualitative studies may be needed to better understand the psychosocial determinants and reasons for the behaviors reflected in the identified trajectories.

Researchers' perspectives on methodological challenges and outcomes selection in interventional studies targeting medication adherence in rheumatic diseases: an OMERACT-adherence study.

BACKGROUND: Research on adherence interventions in rheumatology is limited by methodological issues, particularly heterogeneous outcomes. We aimed to describe researchers' experiences with conducting interventional studies targeting medication adherence in rheumatology and their perspectives on establishing core outcomes. METHODS: Semi-structured interviews using audio conference were conducted with researchers who had conducted an adherence study of any design in the past 10 years. Data collection and thematic analysis were performed iteratively, until saturation. RESULTS: We interviewed 13 researchers, most of whom worked in academia and specialized in epidemiology and/or health services research. We identified three themes: 1) improving measurement of adherence (considering all phases of adherence, using appropriate and relevant measures, and establishing clinically meaningful thresholds); 2) challenges in designing and appraising adherence intervention studies (considering the confusion over a plethora of outcomes, difficulties with powering studies to demonstrate meaningful changes, and suboptimal descriptions of adherence interventions in published studies); and 3) advancing outcome assessment in adherence intervention studies (capturing rationale for developing a core domain set as well as recommendations and anticipated challenges by participants). CONCLUSIONS: Uniquely gathering perspectives from international adherence researchers, our findings led to researcher-informed recommendations for improving adherence research including specifying the targeted adherence phase in designing interventions and studies and providing a glossary of terms to promote consistency in reporting. We also identified recommendations for developing a core domain set for interventional studies targeting medication adherence including involvement of patients, clinicians, and other stakeholders and methodological and practical considerations to establish rigor and support uptake.

Utilization and uptake of clinical genetics services in high-income countries: A scoping review.

Ongoing rapid growth in the need for genetic services has the potential to severely strain the capacity of the clinical genetics workforce to deliver this care. Unfortunately, assessments of the scale of this health policy challenge and potential solutions are hampered by the lack of a consolidated evidence base on the growth in genetic service utilization. To enable health policy research and strategic planning by health systems in this area, we conducted a scoping review of the literature on the utilization and uptake of clinical genetics services in high-income countries published between 2010 and 2018. One-hundred-and-ninety-five unique studies were included in the review. Most focused on cancer (85/195; 44%) and prenatal care (50/195; 26%), which are consistently the two areas with the greatest volume of genetic service utilization in both the United States and other high-income countries. Utilization and uptake rates varied considerably and were influenced by contextual factors including health system characteristics, provider knowledge, and patient preferences. Moreover, growth in genetic service utilization appears to be driven to a significant degree by technological advances and the integration of new tests into clinical care. Our review highlights both the policy challenge posed by the rapid growth in the utilization of genetic services and the variability in this trend across clinical indications and health systems.

Adherence to Antimalarial Therapy and Risk of Type 2 Diabetes Mellitus Among Patients With Systemic Lupus Erythematosus: A Population-Based Study.

OBJECTIVE: To evaluate the association between adherence to antimalarials and type 2 diabetes mellitus (DM) in patients with systemic lupus erythematosus (SLE). METHODS: Using administrative health databases in British Columbia, Canada, we conducted a retrospective, longitudinal cohort study of patients with incident SLE and incident antimalarial use. We established antimalarial drug courses by defining a new course when a 90-day gap is exceeded between refills and we calculated proportion of days covered (PDC) for each course. We categorized medication taking as: 1) adherent (PDC ≥0.90), 2) nonadherent (0 < PDC < 0.90), and 3) discontinuer (no drug). Type 2 DM outcomes were based on outpatient or inpatient visits, or antidiabetic medication use. We used multivariable Cox proportional hazards models with time-dependent variables. RESULTS: Over a median of 4.62 years of follow-up in our incident cohort of 1,498 patients with SLE (90.8% women), we recorded 140 incident cases of type 2 DM. Multivariable hazard ratios were 0.61 (95% confidence interval [95% CI] 0.40-0.93) for adherent and 0.78 (95% CI 0.50-1.22) for nonadherent, respectively, as compared to discontinuers. CONCLUSION: Our findings of a protective effect of adherence to antimalarials in preventing type 2 DM provides further support for the importance of adherence to antimalarials to obtain the benefits of therapy.

Pharmacists' perceptions of their working conditions and the factors influencing this: Results from 5 Canadian provinces.

INTRODUCTION: Our previous study in British Columbia (BC) indicated that pharmacists have a poor perception of their working conditions. The objective of this study is to assess pharmacists' perceptions of their working conditions in 4 other Canadian provinces. METHODS: This was a cross-sectional study across Alberta, New Brunswick, Prince Edward Island and Newfoundland and Labrador, using a survey adapted from the Oregon Board of Pharmacy. Data collected previously from BC were also included in the analyses. The survey was emailed to all pharmacist registrants. Respondents were provided with 6 statements and asked to rate their agreement with them, using a 5-point Likert scale. Statements were framed such that agreement with them indicated good perception of working conditions. Logistic regression analyses were used to study the relationship between workplace factors on perception of working conditions. RESULTS: Pharmacists perceived their working conditions to be poor. Pharmacists indicated that they do not have time for break/lunch (48.3% of respondents), work in environments that are not conducive to safe and effective primary care (26.5%), are not satisfied with the amount of time they have to do their job (44.0%) and face shortage of staff (shortage of pharmacists: 33.7%, technicians: 36.4%, clerk staff: 30.3%). Significant factors associated with poor perception were workplace-imposed quotas, high prescription volume, working in chain pharmacies and long prescription wait times. CONCLUSION: A high percentage of Canadian pharmacists perceived their working conditions to be poor. Considering the patient-related consequences of pharmacists' poor working conditions and the system-related reasons identified behind it, we call for collaborative efforts to tackle this issue.

Adherence to oral anticoagulants among patients with atrial fibrillation: a systematic review and meta-analysis of observational studies.

INTRODUCTION: Medications cannot exert their effect if not taken as prescribed by patients. Our objective was to summarise the observational evidence on adherence to oral anticoagulants (OACs) among patients with atrial fibrillation (AF). METHODS: In March 2019, we systematically searched PubMed/Medline, Embase, CINAHL and PsycINFO (from inception) for observational studies measuring adherence, its determinants and impacts in patients with AF. Mean adherence measures and corresponding proportions of adherent patients were pooled using random effects models. Factors shown to be independently associated with adherence were extracted as well as the clinical and economic outcomes of adherence. RESULTS: We included 30 studies. Pooled mean adherence scores of over half a million patients with AF 6 months and 1 year after therapy initiation were 77 (95% CI: 74-79) and 74 (68-79) out of 100, respectively. Drug-specific pooled mean adherence score at 6 months and 1 year were as follows: rivaroxaban: 78 (73-84) and 77 (69-86); apixaban: 77 (75-79) and 82 (74-89); dabigatran: 74 (69-79) and 75 (68-82), respectively. There was inadequate information on warfarin for inclusion in meta-analysis.Factors associated with increased adherence included: older age, higher stroke risk, once-daily regimen, history of hypertension, diabetes or stroke, concomitant cardiovascular medications, living in rural areas and being an experienced OAC user. Non-adherent patients were more likely to experience stroke and death, and incurred higher medical costs compared with patients with poor adherence. CONCLUSIONS: Our findings show that up to 30% of patients with AF are non-adherent, suggesting an important therapeutic challenge in this patient population.

Atrial fibrillation patients' experiences and perspectives of anticoagulation therapy changes.

BACKGROUND: Atrial fibrillation (AF) patients' experiences with changes in their oral anticoagulant (OAC) therapy are understudied. OBJECTIVE: The objective of this study was to qualitatively describe AF patients' experiences and perspectives of changes made to their OAC therapy (switches or discontinuations). METHODS: A thematic analysis was performed on systematically-collected qualitative data from AF patients who experienced a therapy change (switching or discontinuing an OAC) as part of their participation in a large 2-year prospective observational study. RESULTS: A total of 56 participants met the inclusion criteria. Six themes emerged from the data: 1. reasons for switch or discontinuation of therapy, 2. attitudes towards changes in therapy attributes, 3. challenges with taking medications after therapy change, 4. relief from perceived burden of medication after discontinuation, 5. patients' limited involvement in decision-making, and 6. inadequate education and follow up. Patients were found to request changes in therapy based on their subjective experience with it (rather than clinically justified reasons). They were found to have limited knowledge about their medications, differing reactions to changes in their therapy attributes after a switch, an overall negative attitude towards taking medications, adherence challenges after switching from once daily to twice daily medication, feelings of being excluded from the decision-making process about their therapy changes and feelings of being unsupported after these changes. CONCLUSIONS: There are clear opportunities to improve patients' experiences with OAC therapy changes through improved shared decision-making and patient education/counselling.

Characterization of pharmacist-based medication management services in a community pharmacy.

BACKGROUND: Medication management (MM) refers to all clinical activities that a pharmacist performs to ensure safe and effective medication therapy for patients. OBJECTIVE: To characterize pharmacist-driven MM services via retrospective analysis of real-world data collected in a community pharmacy in British Columbia (BC), Canada. METHODS: This was a retrospective longitudinal study from January 2014-December 2015. Patient demographics, clinical problems, identified drug-related problems (DTPs), and pharmacists' interventions were summarized using descriptive statistics. The relationship between DTPs and the clinical conditions, as well as DTPs and the interventions, were analyzed. Other outcomes included: the relationship between patients' age and visit time with the number of DTPs; the number of clinical conditions; and the number of interventions. RESULTS: 1,572 patients received MM (mean visit time = 29.1 min). 2,133 DTPs were identified, which resulted in 7176 recommended interventions. The clinical problems most frequently encountered were cardiovascular (20%), and mental (15.7%). The most frequently identified DTP was "needs additional therapy" (61.8%), while the most frequently initiated or recommended interventions were education (43.4%), and changing therapy (21.6%). Elderly patients with multiple comorbidities had more DTPs and required more interventions and even when no DTPs were identified, some patients still received counselling and education in these visits. CONCLUSION: Using real-world data, this research demonstrated that patients benefit from identification and resolution of DTPs through pharmacists-driven MM programs.

Scope of Outcomes in Trials and Observational Studies of Interventions Targeting Medication Adherence in Rheumatic Conditions: A Systematic Review.

OBJECTIVE: Nonadherence to medications is common in rheumatic conditions and associated with increased morbidity. Heterogeneous outcome reporting by researchers compromises the synthesis of evidence of interventions targeting adherence. We aimed to assess the scope of outcomes in interventional studies of medication adherence. METHODS: We searched electronic databases to February 2019 for published randomized controlled trials and observational studies of interventions with the primary outcome of medication adherence including adults with any rheumatic condition, written in English. We extracted and analyzed all outcome domains and adherence measures with prespecified extraction and analysis protocols. RESULTS: Overall, 53 studies reported 71 outcome domains classified into adherence (1 domain), health outcomes (38 domains), and adherence-related factors (e.g., medication knowledge; 32 domains). We subdivided adherence into 3 phases: initiation (n = 13 studies, 25%), implementation (n = 32, 60%), persistence (n = 27, 51%), and phase unclear (n = 20, 38%). Thirty-seven different instruments reported adherence in 115 unique ways (this includes different adherence definitions and calculations, metric, and method of aggregation). Forty-one studies (77%) reported health outcomes. The most frequently reported were medication adverse events (n = 24, 45%), disease activity (n = 11, 21%), bone turnover markers/physical function/quality of life (each n = 10, 19%). Thirty-three studies (62%) reported adherence-related factors. The most frequently reported were medication beliefs (n = 8, 15%), illness perception/medication satisfaction/satisfaction with medication information (each n = 5, 9%), condition knowledge/medication knowledge/trust in doctor (each n = 3, 6%). CONCLUSION: The outcome domains and adherence measures in interventional studies targeting adherence are heterogeneous. Consensus on relevant outcomes will improve the comparison of different strategies to support medication adherence in rheumatology.

Health Authority Pharmacists' Perceptions of Independent Pharmacist Prescribing.

BACKGROUND: In many jurisdictions, the pharmacist's role continues to evolve from drug distribution-based service delivery to expanded scopes of practice, including independent prescribing of medications. OBJECTIVES: To assess health authority-based pharmacists' attitudes, beliefs, and perceptions about independent prescribing, to determine how independent prescribing may affect their behaviour, and to identify perceived barriers and enablers to incorporating it into their practice. METHODS: An anonymous, cross-sectional online survey of 677 health authority-based pharmacists employed by Lower Mainland Pharmacy Services in British Columbia collected information in the following domains: demographic characteristics; attitudes, beliefs, and perceptions regarding pharmacist prescribing; anticipated effect of pharmacist prescribing on behaviour; likelihood of applying for this authority, if granted; and barriers and enablers to applying for prescribing authority and incorporating prescribing into their practice. A multivariate regression analysis was performed. RESULTS: A total of 266 pharmacists (39.3%) responded to the survey. Most respondents agreed that prescribing is important to the profession and relevant to their practice, and that it might enhance job satisfaction. Additionally, respondents agreed that they had the expertise to prescribe. Respondents perceived prescribing as having the potential to positively affect behaviour, including deprescribing, prescribing at time of discharge or transfer, and renewing medications. Enablers to applying for pharmacist prescribing authority included perceived positive impact on patient care and the profession, level of support from management and coworkers, and personal ability. No barriers were identified. About two-thirds of pharmacists indicated they would likely apply for prescribing authority if it were granted through legislation. Pharmacists with a clinical practice or research role were significantly more likely to apply to be a prescriber, whereas those with more than 10 years of experience were less likely to apply. CONCLUSIONS: In this study, health authority-based pharmacists held positive attitudes and beliefs about the value and impact of independent prescribing of medications on their practice and the profession. There were no perceived barriers to applying for prescribing authority or to incorporating prescribing into practice.

CONTEXTE: Dans bien des provinces, le rôle du pharmacien ne cesse d'évoluer, depuis la prestation de services fondée sur la distribution de médicaments à des champs de pratique élargis, comprenant le droit de prescription autonome des médicaments. OBJECTIFS: Évaluer les attitudes, les croyances et les opinions des pharmaciens rattachés à des régies de santé concernant le droit de prescription autonome, déterminer l'influence de ce droit sur leurs habitudes et recenser les éléments qui, selon eux, entravent ou facilitent l'intégration de ce droit dans leur pratique. MÉTHODES: Une enquête transversale anonyme en ligne s'adressant à 677 pharmaciens rattachés à une régie de santé et employés par les services de pharmacie des basses-terres continentales en Colombie-Britannique a permis de recueillir de l'information sur les domaines suivants : caractéristiques démographiques; attitudes, croyances et opinions concernant le droit de prescrire des pharmaciens; effets envisagés sur les habitudes du droit de prescrire accordé aux pharmaciens; probabilité de demander ce droit, s'il existe; et les éléments entravant ou facilitant la demande du droit de prescrire et l'intégration de ce droit dans leur pratique. Une analyse de régression multivariée a été réalisée. RÉSULTATS: Au total, 266 pharmaciens (39,3 %) ont répondu au sondage. La plupart d'entre eux ont affirmé que le droit de prescrire est important pour la profession et pertinent dans le cadre de leur pratique et que cet acte pourrait accroître leur satisfaction au travail. De plus, les répondants affirmaient qu'ils possédaient l'expertise requise pour prescrire. Selon eux, le droit de prescrire pouvait influencer positivement leurs habitudes, notamment en ce qui concerne l'interruption de la prescription, la prescription au moment du congé ou d'un transfert et le renouvellement de médicaments. Parmi les éléments incitant les pharmaciens à solliciter le droit de prescrire, on comptait les effets positifs présumés sur les soins offerts aux patients et sur la profession, le soutien de la part de la direction et des collègues et les capacités personnelles. Aucun obstacle n'a été recensé. Environ deux tiers des pharmaciens ont indiqué qu'ils solliciteraient probablement le droit de prescrire s'il était accordé par la loi. Les pharmaciens en pratique clinique et ceux en recherche étaient beaucoup plus enclins à faire la demande pour devenir prescripteurs alors que ceux comptabilisant plus de dix ans d'expérience étaient moins enclins à faire la demande. CONCLUSIONS: Dans la présente étude, les pharmaciens rattachés à une régie de santé affichaient une attitude et des croyances positives à propos de la valeur du droit de prescription autonome des médicaments et des effets qu'il aurait sur leur pratique et la profession. On n'a recensé aucun élément perçu comme un obstacle à la formulation d'une demande du droit de prescrire ou à l'inclusion de ce rôle dans la pratique.

Assessment of Condition and Medication Knowledge Gaps Among Atrial Fibrillation Patients: A Systematic Review and Meta-analysis.

Background: Patient education facilitates construction of a correct illness representation, improves beliefs about medications, and improves knowledge, factors that have been associated with better adherence. Objective: Our objective was to characterize the published literature about atrial fibrillation (AF) patients' disease and medication knowledge to identify knowledge gaps and misconceptions to inform AF patient education strategies. Methods: Following PRISMA guidelines, we searched PubMed, EMBASE, CINAHL, and PsychINFO from inception to May 2018 for studies that assessed AF patients' knowledge about their condition and medications. For quantitative studies, we extracted the proportion of participants who provided correct answers to the questions asked about their condition, medications, or risk of stroke. We classified data for related questions into knowledge domains. A random-effects meta-analysis was conducted for each knowledge domain. A domain was considered a knowledge gap if the pooled mean proportion of participants who demonstrated knowledge of it was ≤50%, regardless of CI. Qualitative data were summarized narratively. Results: A total of 21 studies were included. AF- and stroke-related knowledge gaps and misconceptions included the following: AF can be asymptomatic, AF can predispose to heart failure, women are at a higher risk of stroke, the definition of ischemic stroke, and patients' awareness of their diagnosis. Medication-related knowledge gaps were antithrombotic-drug interactions, antithrombotic-food interactions, vitamin K content of foods, the term INR (international normalized ratio) and its interpretation, and the required actions in case of a missed dose. Conclusion and Relevance: This systematic review identified several AF patient knowledge gaps about their condition and its treatment that can inform the development of AF patient education programs.

Evaluating the Effect of a Patient Decision Aid for Atrial Fibrillation Stroke Prevention Therapy.

BACKGROUND: Stroke prevention therapy decisions for patients with atrial fibrillation (AF) are complex and require trade-offs, but few validated patient decision aids (PDAs) are available to facilitate shared decision making. OBJECTIVE: To evaluate the effects of a novel PDA on decision-making parameters for AF patients choosing stroke prevention therapy. METHODS: We developed an evidence-based individualized online AF PDA for stroke prevention therapy and evaluated it in a prospective observational pilot study. The primary outcome was decisional conflict. Secondary outcomes were knowledge, usability/acceptability, patient preferences, effects on therapy choices, and participant feedback. RESULTS: 37 participants completed the PDA. The PDA could be completed independently and was well accepted. It significantly decreased the mean decisional conflict score ( P < 0.001) and all its subscales and increased participant AF knowledge ( P = 0.02). 76% of participants indicated that their individualized therapy attribute ranking was congruent with their values. The PDA-generated best-match therapy was chosen by 70% of participants in decision 1 (no therapy, aspirin, or oral anticoagulant), and 17% for decision 2 (choice of anticoagulant). Among AF patients, 60% chose a different drug than that currently prescribed to them. Conclusion and Relevance: Our PDA was effective for reducing decisional conflict, increasing patient knowledge, eliciting patients' values, and presenting therapy options that aligned with patients' values and preferences. Using the PDA revealed that many patients have therapy preferences different from their currently prescribed treatment. The PDA is a practical and potentially valuable tool to facilitate decision making about stroke prevention therapy for AF.

Assessment of atrial fibrillation patients' education needs from patient and clinician perspectives: A qualitative descriptive study.

INTRODUCTION: Patients' lack of knowledge is a key barrier to therapy adherence. We aimed to gather insights into atrial fibrillation (AF) patients' education needs from patient and clinician viewpoints. METHODS: We conducted a qualitative descriptive study using purposive sampling and semi-structured interviews with AF patients and clinicians recruited from AF clinics. Data from patients and clinicians were analyzed independently and iteratively through inductive qualitative thematic analysis. RESULTS: Eleven clinicians and 10 patients were interviewed. Three themes emerged from analysis of clinician data: (1) patients' knowledge gaps and misconceptions, (2) clinicians' experiences teaching AF patients, and (3) clinicians' suggestions for AF education programs. Four themes emerged from the patient data: (1) emotional appraisal of the disease, (2) information seeking behavior, (3) knowledge gaps, and (4) education preferences. A key finding was identification of the need for education that addresses patients' unjustified anxieties by emphasizing that AF is not fatal, and that many patients with AF live a normal life. Risk communication was identified as the most challenging aspect of AF education. In synthesizing our findings, we developed evidence-based recommendations for educational strategies for AF. CONCLUSION: We found that AF patients have many knowledge gaps and misconceptions, significant emotional education needs, and a positive attitude towards online and classroom education. In synthesizing our findings, we developed evidence-based recommendations which can inform the design of AF patient education programs and initiatives.

Efficacy and Safety of Cyclosporine in Acute Myocardial Infarction: A Systematic Review and Meta-Analysis.

There are various studies that have addressed the use of Cyclosporine among patients with acute myocardial infarction (AMI). However, to date there is hardly any concise and systematically structured evidence that debate on the efficacy and safety of Cyclosporine in AMI patients. The aim of this review is to systematically summarize the overall evidence from published trials, and to conduct a meta-analysis in order to determine the efficacy and safety of Cyclosporine vs. placebo or control among patients with AMI. All randomized control trial (RCT) published in English language from January 2000 to August 2017 were included for the systematic review and meta-analysis. A total of six RCTs met the inclusion and were hence included in the systematic review and meta-analysis. Based on the performed meta-analysis, no significant difference was found between Cyclosporine and placebo in terms of left ventricular ejection fraction (LVEF) improvement (mean difference 1.88; 95% CI -0.99 to 4.74; P = 0.2), mortality rate (OR 1.01; 95% Cl 0.60 to 1.67, P = 0.98) and recurrent MI occurrence (OR 0.65; 95% Cl 0.29 to 1.45, P = 0.29), with no evidence of heterogeneity, when given to patients with AMI. Cyclosporine also did not significantly lessen the rate of rehospitalisation in AMI patients when compared to placebo (OR 0.91; 95% Cl 0.58 to 1.42, P = 0.68), with moderate heterogeneity (I2 = 46%). There was also no significant improvement in heart failure events between Cyclosporine and placebo in AMI patients (OR 0.63; 95% Cl 0.31 to 1.29, P = 0.21; I2 = 80%). No serious adverse events were reported in Cyclosporine group across all studies suggesting that Cyclosporine is well tolerated when given to patients with AMI. The use of Cyclosporine in this group of patients, however, did not result in better clinical outcomes vs. placebo at improving LVEF, mortality rate, recurrent MI, rehospitalisation and heart failure event.
