Integrated Care for Atrial Fibrillation Management: The Role of the Pharmacist

Improving patient safety and access to healthcare: The role of pharmacist-managed clinics in optimizing therapeutic outcomes

Contemporary patient care requires a multidisciplinary approach to monitoring, assessing, and managing diseases. Promoting multidisciplinary approaches encourages the purposeful participation of many healthcare professionals and harnessing their combined knowledge to provide tailored treatment plans. Pharmacists, skilled and knowledgeable professionals in medication management, drug-related problems, and disease prevention, can offer vital interventions that contribute to improved patient outcomes. Advances in healthcare and information technology have expanded pharmacists' professional roles and made them essential in healthcare. Pharmacist-managed clinics (PMCs), an innovative healthcare approach, could potentially improve patient safety, satisfaction, accessibility, and affordability to quality healthcare. Spread across the healthcare continuum, pharmacists have a well-defined role in providing comprehensive pharmaceutical care and interprofessional collaboration, further reinforcing the necessity of establishing PMCs. This narrative review aims to compile and summarize information on PMCs from PubMed, Scopus, Web of Science, and Google Scholar till December 2023. The PMC shortlist covers specialties such as cardiovascular, hematologic, endocrine, pain medicine, respiratory medicine, infectious diseases, gastrointestinal, nephrology, neurology, and oncology. Pharmacists in disease-specific PMCs have demonstrated improved treatment outcomes and access to specialty care. Additionally, based on peer-reviewed literature, the review also highlights how PMCs enhance the pharmacist's role in improving disease-specific outcomes, overall quality of care, and medication management. The inclusion criteria are randomized controlled trials, case-control studies, cohort studies, and pre-post studies involving patients from cardiology, hematology, endocrinology, pain medicine, respiratory medicine, infectious diseases, neurology, nephrology, gastroenterology, and oncology specialties, focusing on pharmacist-driven clinics, published in English, and covering any geographical location. The exclusion criteria include review articles, proposed models, commentaries, editorials, and those published in languages other than English. Our findings reveal that PMCs are underutilized globally. PMCs work better in developed countries, possibly on account of robust healthcare infrastructure, adequate healthcare budgets, availability of trained pharmacists, and supportive regulatory environments. The review found that pharmacist-led interventions, such as medication monitoring and patient education, significantly enhance therapeutic outcomes. Pharmacist Managed Clinics improve affordability and acceptability, expanding healthcare access in outpatient and inpatient settings. This review also highlights the critical need for implementing PMCs to improve healthcare delivery, particularly in providing comprehensive and accessible services in developing countries.

The effect of pharmacist-led interventions on the appropriateness and clinical outcomes of anticoagulant therapy: a systematic review and meta-analysis

AIM

Although pharmacist-led interventions in anticoagulant (AC) therapy are widely accepted, there is a lack of evidence comparing their effectiveness with usual care in terms of AC therapy appropriateness and clinical outcomes. We aimed to estimate the comparative effectiveness of pharmacist-led interventions on the appropriateness and clinical outcomes of AC therapy.

METHODS AND RESULTS

Adhering to the PRISMA guidelines, we searched PubMed, EMBASE, and Scopus databases to identify randomized controlled trials and quasi-experimental and cohort studies published between 2010 and 2023. A random-effects model was used to calculate pooled intervention effects. We assessed heterogeneity (using Higgins' I2 and Cochran's Q) and publication bias (using Egger's test, the trim-and-fill method, and visualization of the funnel plot). In total, 35 studies involving 10 374 patients in the intervention groups and 11 840 in the control groups were included. The pharmacist-led interventions significantly improved the appropriateness of AC therapy [odds ratio (OR): 3.43, 95% confidence interval (CI): 2.33-5.06, P < 0.01]. They significantly decreased total bleeding [relative risk (RR): 0.75, 95% CI: 0.58-0.96, P = 0.03) and hospitalization or readmission (RR: 0.64, 95% CI: 0.41-0.99, P = 0.04). However, the impact of the pharmacist-led interventions on thromboembolic events (RR: 0.69, 95% CI: 0.46-1.02, P = 0.07) and mortality (RR: 0.76, 95% CI: 0.51-1.13, P = 0.17) was not significant.

CONCLUSION

Pharmacist-led interventions demonstrated superior outcomes in optimizing AC therapy compared with usual care. Further research is needed to evaluate pharmacist-led interventions' cost-effectiveness and long-term sustainability. PROSPERO registration number: CRD42023487362.

Pharmacy-Led Management of Atrial Fibrillation: Improving Treatment Adherence and Patient Outcomes

The world's population is ageing, with the number of those over 60 years expected to represent a fifth of the total population by 2050. Increases in chronic long-term health conditions (LTCs) associated with ageing, and requiring regular but often avoidable medical intervention, are pressurising already overloaded, health and social care systems. Atrial fibrillation (AF) is an LTC, which is most frequently diagnosed in the elderly. An often, asymptomatic condition, AF is associated with a 3- to 5-fold increased risk of severe ischemic stroke. Stroke prevention, with risk-stratified oral anticoagulants (OACs) is the standard recommended care for patients with AF. Stroke avoidance is, however, dependent on persistent adherence to OAC medication, with an adherence rate of >80% considered necessary to achieve optimal health outcomes. Suboptimal adherence to OACs is common, with a third of all AF patients not taking their medication as prescribed. This combined with the short half-life of OACs can result in poor clinical outcomes for patients. Policy makers now consider improving adherence to prescribed medicines for LTCs, a public health priority, to ensure better health outcomes for patients, whilst minimising unnecessary health system costs. Prescribing medicines to treat LTCs, such as AF, is not enough, particularly when the patient may not experience any measurable benefit to the treatment and may instead, experience medication-associated adverse events, including a risk of bleeding. Pharmacists who are experts in medicines management are ideally placed to support medication adherence, to educate, and to improve health outcomes for patients with AF. In this review, I will consider the evidence for poor medication adherence in LTCs and in particular adherence to OACs in patients with AF and highlight the role that pharmacists can play in ensuring optimal adherence and showcase pharmacist-led interventions that effectively address this problem.

Pharmacist-led intervention for older people with atrial fibrillation in long-term care (PIVOTALL study): a randomised pilot and feasibility study

BACKGROUND

Older care home residents are a vulnerable group of people with atrial fibrillation (AF) at high risk of adverse health events. The Atrial Fibrillation Better Care (ABC: Avoid stroke; Better symptom management; Cardiovascular and other comorbidity management) pathway is the gold-standard approach toward integrated AF care, and pharmacists are a potential resource with regards to its' implementation. The aim of this study was to determine the feasibility of pharmacist-led medicines optimisation in care home residents, based on the ABC pathway compared to usual care.

METHODS

Individually randomised, prospective pilot and feasibility study of older (aged ≥ 65 years) care home residents with AF (ISRCTN14747952); residents randomised to ABC pathway optimised care versus usual care. The primary outcome was a description of study feasibility (resident and care home recruitment and retention). Secondary outcomes included the number and type of pharmacist medication recommendations and general practitioner (GP) implementation.

RESULTS

Twenty-one residents were recruited and 11 (mean age [standard deviation] 85.0 [6.5] years, 63.6% female) were randomised to receive pharmacist-led medicines optimisation. Only 3/11 residents were adherent to all three components of the ABC pathway. Adherence was higher to 'A' (9/11 residents) and 'B' (9/11 residents) components compared to 'C' (3/11 residents). Four ABC-specific medicines recommendations were made for three residents, and two were implemented by residents' GPs. Overall ABC adherence rates did not change after pharmacist medication review, but adherence to 'A' increased (from 9/11 to 10/11 residents). Other ABC recommendations were inappropriate given residents' co-morbidities and risk of medication-related adverse effects.

CONCLUSIONS

The ABC pathway as a framework was feasible to implement for pharmacist medication review, but most residents' medications were already optimised. Low rates of adherence to guideline-recommended therapy were a result of active decisions not to treat after assessment of the net risk-benefit.

Pharmacist management of atrial fibrillation in UK primary care: a qualitative study

BACKGROUND

Atrial fibrillation (AF) affects up to 2% of the UK population. AF is a potentially long-term condition that needs management, and as such primary care pharmacists may have a substantial role in supporting the management of AF.

OBJECTIVES

This study aims to explore the role of primary care pharmacists, working in community pharmacies and general practices (GPs), in supporting the management of AF. Furthermore, this study investigates pharmacists' confidence in their knowledge and their attitudes towards incorporating AF-associated mobile apps use into their current practice.

METHODS

A qualitative study was conducted, using one-to-one semi-structured, audio-recorded interviews with primary care pharmacists. The topic guide was developed based on pharmacy visits and included the most relevant constructs from the 'consolidated framework for implementation research (CFIR)'. All interviews were audio-recorded, transcribed verbatim and thematically analysed until saturation was achieved, guided by Braun and Clarke's 6-step research method. This study was given a favourable opinion on 5 September 2019 by the University of Birmingham (UOB) Research Ethics Committee (Reference ERN_19-0908).

RESULTS

Thematic saturation was achieved after 11 interviews with primary care pharmacists (seven community pharmacists, and four GP pharmacists). Three main themes emerged relating to (1) the clinical role of pharmacists in the management of AF; (2) knowledge and awareness; and (3) prioritisation of resources. The first highlighted that primary care pharmacists were an underutilised resource within AF management. The second demonstrated that pharmacists, especially those based in the community, felt a lack of confidence in their knowledge of AF and its management, mainly community pharmacists due to other roles taking precedence over clinical roles. Both community and GP pharmacists expressed the need to have further training in this therapeutic area to be able to effectively support patients with AF. The third shed light on the pharmacists' views relating to the technological revolution in healthcare. Pharmacists expressed an interest in using apps to support their current practice.

CONCLUSIONS

Primary care pharmacists supported an extended care to AF management from screening to consultations, yet the provision of such services remains limited and inconsistent. Future research should focus on understanding the ways in which pharmacists' role can be adapted toward greater involvement in clinical care.
