Stroke risk assessment for atrial fibrillation: hospital-based stroke risk assessment and intervention program

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

Within Europe and the Asia-Pacific, the Atrial Fibrillation Better Care (ABC) pathway is the gold standard integrated care strategy for atrial fibrillation management. Atrial fibrillation diagnosis should be confirmed and characterized (CC) prior to implementation of ABC pathway components: 1) "A"- Anticoagulation/Avoid stroke; 2) "B"- Better symptom management; and 3) "C"- Cardiovascular and other comorbidity optimization. Pharmacists have the potential to expedite integrated care for atrial fibrillation across the health care continuum: hospital, community pharmacy, and general practice. This review summarizes the available evidence base for pharmacist-led implementation of the "CC to ABC" model.

The Role of Pharmacists in Providing Pharmaceutical Care in Primary and Secondary Prevention of Stroke: A Systematic Review and Meta-Analysis

Pharmacists deliver pharmaceutical care in many different healthcare settings and are well-placed to support the prevention of stroke. However, their role and impact in this area is ill-defined. This systematic review aims to explore the pharmacists’ role in stroke prevention. Nine databases were searched for studies reporting pharmacist interventions in the management of primary and secondary ischaemic stroke prevention. Study quality was evaluated through Cochrane Risk of Bias and Joanna Briggs Institute (JBI) appraisal tools where possible. A narrative review was conducted and meta-analysis performed for studies with comparable outcomes. Of the 834 initial articles, 31 met inclusion criteria. Study designs were varied and included controlled trials, observational studies, audit reports and conference abstracts. Seven studies addressed the pharmacists’ role in primary prevention and 24 in secondary prevention. Pharmacist interventions reported were diverse and often multifactorial. Overall, 20 studies reported significant improvement in outcomes. Meta-analysis showed pharmacist interventions in emergency care significantly improved the odds of achieving thrombolytic therapy door to needle (DTN) times ≤45 min, odds ratio: 2.69 (95% confidence interval (CI): 1.95−3.72); p < 0.001. The pharmacists’ role is varied and spans the stroke treatment pathway, with the potential for a positive impact on a range of health-related outcomes.

Anticoagulant Use in Patients With Nonvalvular Atrial Fibrillation: Has Prescribing Improved?

Discordance between international guideline recommendations and anticoagulant prescribing patterns among patients with nonvalvular atrial fibrillation (NVAF) has been frequently reported. This study was designed to compare the anticoagulant utilization pattern to earlier data in the same population and identify predictors of anticoagulant prescribing among patients with NVAF. We reviewed patients with NVAF admitted to Tasmania’s 3 major hospitals between January 2011 and June 2012 and compared the anticoagulant utilization pattern to earlier data. Patients were excluded if they had only 1 episode of NVAF that reverted spontaneously or upon cardioversion. Multivariate logistic regression analysis was used to identify predictors of anticoagulant prescribing. Overall, 53.8% of patients received anticoagulant treatment compared to 40.4% 15 years ago. Among eligible patients at high-risk of stroke, 52.5% were receiving anticoagulant therapy (vs 42.1% 15 years ago). Approximately 10% of patients with a CHADS2 score ≥2 were not receiving any antithrombotic treatment, reduced from 18.2% in the earlier cohort, whereas anticoagulant use increased among those at low risk (score 0) to 48.5% from 14.2%. Younger age (odds ratio [OR] 0.99, 95% confidence interval [CI] 0.97-1.0; P = .04); CHADS2 = 1, relative to 0 (OR 1.68, 95% CI 1.07-2.63; P = .02); CHF (OR 1.56, 95% CI 1.12-2.15; P = .008); and embolic disease history (OR 1.77, 95% CI 1.09-2.86; P = .02) were significant predictors of anticoagulant prescribing. While there has been improvement over the past 15 years, suboptimal use of anticoagulant therapy among high-risk patients with NVAF remains common. There is significant potential for improvement in the quality of stroke prophylaxis in patients with NVAF.

Patient Characteristics and Antithrombotic Prescribing Patterns in Patients With Atrial Fibrillation in Tasmania

Limited data are available on atrial fibrillation (AF) and its clinical management and outcomes from an Australian perspective. This study was designed to examine the patient characteristics and antithrombotic treatment patterns among patients with AF in Tasmania, Australia. This retrospective observational study reviewed and followed patients with AF admitted to Tasmania’s 3 major hospitals between January 2011 and June 2012. Patients were excluded if they had only 1 episode of AF that reverted spontaneously or upon cardioversion without any documented recurrences. We reviewed the records of 2502 patients (≥18 years), and1469 were subsequently included in the study. The mean (±standard deviation [SD]) age of the patients was 76 (±12.3) years. The mean (± SD) CHADS2 score was 2.1 (±1.3), and 65.7% had a score ≥2. In total, only 55.6% of patients with CHADS2 score ≥2 were receiving anticoagulation and 9.9% were not receiving any antithrombotic treatment, whereas 85.4% of those at low risk (score 0) were on antithrombotic therapy. Hospitalization was associated with a significant increase in the rate of combination (antiplatelet plus anticoagulant) therapy ( P < .001). Suboptimal use of antithrombotic therapy highlights the need to improve AF management in our jurisdiction.

Pharmacists' awareness of Australia's health care reforms and their beliefs and attitudes about their current and future roles

Objective

To explore pharmacists' awareness of Australia's health care reforms and their beliefs and attitudes about their current and future roles.

Methods

Four focus groups were conducted with 32 South Australian pharmacists: two groups included community pharmacists and pharmacy owners; one included hospital pharmacists and another, consultant pharmacists.

Key findings

Four themes emerged: (1) poor awareness of health care reform agenda; (2) strong adherence to the supply model; (3) lack of appreciation of alternative models; and (4) communication barriers.

Conclusions

Participants' low awareness of Australia's health care reforms and their expressed beliefs and attitudes to their current role in the health system suggest that they are not well prepared for the potential future roles expected of health professionals in the health care reform agenda.
