Although highly effective, warfarin use is complicated by its unpredictable narrow therapeutic window, genetic heterogeneity in pharmacokinetic response, numerous food and drug interactions, and the need for regular international normalized ratio (INR) monitoring. Currently, several novel oral anticoagulant (NOAC) drugs (dabigatran, rivaroxaban, apixaban) are available on the market as alternatives to warfarin. These agents all feature more predictable pharmacodynamic and pharmacokinetic properties than warfarin. Additionally, the NOACs do not require routine monitoring of coagulation parameters, and have a relatively lower potential for interactions with drug, herb, and dietary constituents, which enhances the convenience of management for both patients and health professionals alike. However, there are other considerations regarding the use of NOACs that must be taken into account during management of therapy. In contrast to warfarin, most NOACs need dosage adjustments in renal impairment and are contraindicated in severe liver impairment, and there are no specific antidotes for treating NOAC-related over-anticoagulation. The more frequent dosing needed for NOACs may reduce adherence, especially in elderly patients with polypharmacy. Furthermore, NOACs, especially dabigatran, are not as well tolerated as warfarin in patients with gastrointestinal diseases. Overall, the availability of the NOACs has expanded the treatment armamentarium, but they are not without risk. Given the limited experience with the NOACs, their limited range of indications, and their cost, the characteristics of each anticoagulant must be carefully considered to carefully select the agent that will provide the optimal risk/benefit profile in the individual patient.
Wang, Y. & Bajorek, B. 2014, 'Safe use of antithrombotics for stroke prevention in atrial fibrillation: consideration of risk assessment tools to support decision-making.', Ther Adv Drug Saf, vol. 5, no. 1, pp. 21-37.
View/Download from: Publisher's site
Clinical guidelines advocate stroke prevention therapy in atrial fibrillation (AF) patients, specifically anticoagulation. However, the decision to initiate treatment is based on the risk (bleeding) versus benefit (prevention of stroke) of therapy, which is often difficult to assess. This review identifies available risk assessment tools to facilitate the safe and optimal use of antithrombotic therapy for stroke prevention in AF. Using key databases and online clinical resources to search the literature (1992-2012), 19 tools have been identified and published to date: 11 addressing stroke risk, 7 addressing bleeding risk and 1 integrating both risk assessments. The stroke risk assessment tools (e.g. CHADS2, CHA2DS2-VASc) share common risk factors: age, hypertension, previous cerebrovascular attack. The bleeding risk assessment tools (e.g. HEMORR2HAGES, HAS-BLED) share common risk factors: age, previous bleeding, renal and liver impairment. In terms of their development, six of the stroke risk assessment tools have been derived from clinical studies, whilst five are based on refinement of existing tools or expert consensus. Many have been evaluated by prospective application to data from real patient cohorts. Bleeding risk assessment tools have been derived from trials, or generated from patient data and then validated via further studies. One identified tool (i.e. Computerised Antithrombotic Risk Assessment Tool [CARAT]) integrates both stroke and bleeding, and specifically considers other key factors in decision-making regarding antithrombotic therapy, particularly those increasing the risk of medication misadventure with treatment (e.g. function, drug interactions, medication adherence). This highlights that whilst separate tools are available to assess stroke and bleeding risk, they do not estimate the relative risk versus benefit of treatment in an individual patient nor consider key medication safety aspects. More effort is needed to synthesize these separate risk assessments and integrate key medication safety issues, particularly since the introduction of new anticoagulants into practice.

Objective Evidence from pivotal clinical trials conducted more than a decade ago supports the use of antithrombotic therapy, particularly warfarin, for stroke prevention in atrial fibrillation (AF). Despite the wide dissemination of this evidence since that time, there is anecdotal evidence that utilisation of therapy remains suboptimal, especially in the target elderly population, which is reflected in the development of practice tools such as the TAG Clinical Indicator ('Antithrombotics in AF' Indicator 1.6, 2007). Therefore, the objective of this study was to determine the current utilisation of antithrombotic therapy for elderly patients with AF in the local setting, and to compare this utilisation with the results of a prior audit (AUDIT 1), as well as against the recommendations of the TAG Clinical Indicator(TAG IND).

Warfarin is a high-risk medication where patient information may be critical to help ensure safe and effective treatment. Considering the time constraints of healthcare providers, the internet can be an important supplementary information resource for patients prescribed warfarin. The usefulness of internet-based patient information is often limited by challenges associated with finding valid and reliable health information. Given patients' increasing access of the internet for information, this study investigated the quality, suitability and readability of patient information about warfarin presented on the internet.

Thrombolysis is currently the only evidence-based pharmacological treatment available for acute ischaemic stroke (AIS); however, its current utilization is suboptimal (administered to <3% of AIS patients). The aim of this article was to identify the potential barriers to the use of thrombolysis via a review of the available literature. Methods: Medline, Embase, International Pharmaceutical Abstracts and Google Scholar were searched to identify relevant original articles, review papers and other literature published in the period 1995-2011. Results and Discussion: Several barriers to the utilization of thrombolysis in stroke have been identified in the literature and can be broadly classified as 'preadmission' barriers and 'post-admission' barriers.The most effective interventions appear to be those comprising several strategies and those that target more than one barrier simultaneously. Therefore, optimal utilization of thrombolysis requires a systematic, integrated multidisciplinary approach across the continuum of acute care.

Background: Effective management of warfarin therapy is often challenged by its complex pharmacology and preventable adverse events. One strategy to ensure safe warfarin use is provision of comprehensive warfarin education to patients. Aim: To review the provision of warfarin education to hospital patients prescribed warfarin and to describe patient characteristics that may impact on warfarin education. Method: A prospective study was undertaken at 2 large Australian metropolitan hospitals. Provision of warfarin education was identified by auditing the medication charts and clinical notes of hospitalised older patients (= 65 years). Patients were also interviewed to confirm whether they recalled receiving warfarin education during their hospital stay. Results: Data were collected for 96 patients with a mean age of 74 (SD 13) years. Most patients (78%) were admitted to medical wards, were taking warfarin for atrial fibrillation (56%), and had started warfarin prior to admission (54%). 36% of patients had provision of warfarin education documented in medication charts and clinical notes, and in most cases warfarin education was provided by a pharmacist. Of the 68 patients available for interview, only 47% recalled receiving warfarin education; in the majority of cases they cited pharmacists as providers of the education. Conclusion: There is a need to improve documentation and provision of warfarin education to hospital patients

Background: Medication-taking behavior, specifically non-adherence, is significantly associated with treatment outcome and is a major cause of relapse in the treatment of psychotic disorders. Non-adherence can be multifactorial; however, the rates and associated risk factors in an Ethiopian population have not yet been elucidated. The principal aim of this study was to evaluate adherence rates to antipsychotic medications, and secondarily to identify potential factors associated with non-adherence, among psychotic patients at tertiary care teaching hospital in Southwest Ethiopia. Methods: A cross-sectional study was conducted over a 2-month period in 2009 (January 15th to March 20th) at the Jimma University Specialized Hospital. Adherence was computed using both a compliant fill rate method and self-reporting via a structured patient interview (focusing on how often regular medication doses were missed altogether, and whether they missed taking their doses on time). Data were analyzed using SPSS for windows version 16.0, and chi-square and Pearsons r tests were used to determine the statistical significance of the association of variables with adherence.

Introduction Over the past decade medication review services have been implemented in many countries, including Australia, UK and USA. Although, the attitudes and barriers to the implementation of evidence-based medicine have been investigated, the extent to which medication review recommendations are evidence-based is not known. Objective To determine (1) the extent to which pharmacists recommendations during medication review services were consistent with the evidence-based guides at the time of the review; and (2) the nature and extent of drug-related problems (DRPs) and the actions recommended by pharmacists to resolve DRPs. Method A retrospective review of Home Medicines Review cases performed on 224 community-dwelling older people (65 years or older). The chi-squared test for categorical variables was used to compare the proportion of recommendations that were evidencebased and recommendations for which no evidence could be identified in the most common Australian information sources. DRPs and the actions recommended to resolve the DRPs were classified according to previously employed criteria. Results Pharmacists made a total of 1114 therapeutic recommendations to general practitioners, of which 964 required supporting pharmacotherapeutic evidence. The majority (94%) of the pharmacists recommendations were in accordance with the evidence-based guides, as compared with the recommendations for which no evidence could be identified (P < 0.001). Pharmacists reported that 98% of the patients had at least one problem with use of their medication detected.

Aim: To implement a pharmacist charting service in the pre- admission clinic (PAC) and describe a preparatory process for the initiation of this service. Method: Stage 1: a proposal for a pharmacist charting service in the PAC was devised via an iterative process with an advisory panel. Stage 2: feedback on the proposal was obtained from key staff via a survey comprising 15 linear scale statements (0 = strongly disagree to 10 = strongly agree) and openended questions. Stage 3: baseline data were collected on existing PAC service outcomes, e.g. consultation times, accuracy of medication charts.

Aim: To develop and evaluate a novel Computerised Antithrombotic Risk Assessment Tool (CARAT) to aid clinicians decision making regarding the riskbenefit of antithrombotic therapy in older patients. Methods: CARAT was developed in an iterative process involving multidisciplinary feedback and computerisation of previously trialled algorithms. Hospital-based clinicians then applied the tool to patient cases, to evaluate its usability. Results: Overall, 94% of clinicians (n = 27 yielding 216 responses) were satisfied with CARATs format. Most (72%) clinician responses agreed with CARAT recommendations; over two-thirds agreed with estimates of stroke and bleeding risk. However, geriatricians were 3.5 times more likely to disagree with CARAT recommendations than cardiologists, particularly in cases of high fall risk. Overall, 63% responded that CARAT was at least `somewhat useful for clinical practice; 22% indicating it was `very useful. Conclusion: CARAT has potential as a useful decision-support tool to assist clinicians in decision making regarding appropriate antithrombotic therapy in older patients.

View/Download from: Publisher's site
Anticoagulant drugs maintain a high potential for adverse events due to their inherent risk of haemorrhage and/or complex pharmacology. In addition, compromising the safety of these agents is the context in which they are principally used; that is, in the long-term prevention of thromboembolic diseases in an older patient population. These challenges are especially pronounced in the prevention of stroke in older persons with atrial fibrillation (AF), where the need for thromboprophylaxis is paramount and in whom the arrhythmia is most prevalent, but where the target population is simultaneously at high risk of adverse drug events. Essentially, this translates to the use of high-risk therapies on an indefinite basis, in persons who have multiple comorbidities, use polypharmacy, and who may have age-related functional and cognitive decline, culminating in a higher potential for medication misadventure. For this reason, anticoagulants mandate extra pharmacovigilance, and therefore the aim of this review is to address some of the key safety considerations in the use of anticoagulant drugs (warfarin, dabigatran, rivaroxaban), spanning the initiation of therapy to its ongoing management. Using the Medication Management Pathway (MMP) as a framework, in this review we canvas and highlight specific developments in practical strategies to facilitate the safe use of anticoagulants (particularly warfarin) in 'at-risk' elderly patients including: comprehensive risk/benefit assessment using novel risk stratification tools; focused medicines review services; therapeutic drug monitoring services delivered in the primary care setting; and practical education strategies and resources targeting the older patient population. Until newer alternative anticoagulants become viable options for widespread use, clinicians will necessarily need to rely on specific resources and interventions to facilitate the safe use of currently available anticoagulants (i.e. warfarin) in 'at-risk' older people.

Evidence-based therapies (EBTs) for the prevention of cardiovascular disease (CVD) are reportedly underutilized in older people. The primary purpose of this study was to evaluate the use of EBTs for the prevention of CVD events in older people and secondarily whether a Home Medicines Review (HMR) service by pharmacists predicts the use of these medicines. A retrospective cross-sectional audit of HMR reports pertaining to 608 community-dwelling older people (65 years) was conducted. EBTs considered for this audit included four guideline-recommended therapies for CVD: antithrombotic therapy (warfarin+antiplatelet therapy), b-blockers, statins, and angiotensin agents (angiotensin-converting enzyme inhibitors [ACEI]+angiotensin II receptor blockers [ARBs]).

Background: Anticoagulation control is a strong predictor of clinical outcomes for patients on warfarin. Aim: To identify instances of excessive anticoagulation in hospitalised patients on warfarin and to determine the causes of international normalised ratios (INRs) of 5 and above and the management strategies used to correct it. Method: An observational descriptive study undertaken at a teaching hospital over a 3-month period. Data were reviewed prospectively and retrospectively to measure the percentage of time patients were maintained within their target INR range while in hospital and to identify cases of excessive anticoagulation. Patients were divided into a control group (INR < 5) and a high INR group (INR . 5). Possible causes of INRs of 5 and above and its management strategies were recorded.
Kung, M. & Bajorek, B. 2008, 'Medications in pregnancy: Impact on time to lactogenesis after parturition', Journal of Pharmacy Practice and Research, vol. 38, no. 3, pp. 205-208.
Background: Although the many factors that affect the initiation of lactation have been identified, the impact of medications on lactogenesis remains largely unknown. Aim: To explore the impact of medications used during pregnancy on time to lactogenesis after parturition. Method: Data were collected prospectively from women admitted to a metropolitan Sydney hospital for parturition. Information was obtained via a short interview with each patient, as well as from medical notes, drug charts and infant feeding charts.

Background: Despite numerous guidelines and consensus statements on venous thromboembolism (VTE) prophylaxis, there appears to be a large gap between evidence and practice. Aim: To identify the incidence of VTE, thromboprophylaxis practice, VTE risk factors, and bleeding complications in patients undergoing elective total hip or knee arthroplasty. Method: Patients who underwent elective total hip or knee arthroplasty from 1 January 2004 to 31 December 2005 were identified retrospectively from medical records at two hospitals. A clinical case audit was performed and data collected on the 3- month incidence of VTE, thromboprophylaxis practice, VTE risk factors and bleeding episodes.
Nguyen, N. & Bajorek, B. 2008, 'Pharmacist prescribing in warfarin therapy: Exploring clinical utility in the hospital setting', Journal of Pharmacy Practice and Research, vol. 38, no. 1, pp. 35-39.
Background: Managing warfarin therapy can be challenging and a multidisciplinary approach to achieve optimal outcomes can be beneficial. Internationally, extended roles for pharmacists have involved collaborative prescribing privileges. Aim: To explore the clinical utility and capacity of pharmacists to undertake prescribing functions in anticoagulation management in the hospital setting. Methods: Pharmacists were recruited from a large Sydney teaching hospital. A questionnaire was used to simulate a pharmacist prescribing function and to explore their opinion of the usefulness of prescribing and their confidence to undertake such roles. The appropriateness of pharmacists prescribing decisions was evaluated.
Glover, S. & Bajorek, B. 2008, 'Exploring point-of-care testing of capillary blood in warfarin management', Journal of Pharmacy Practice and Research, vol. 38, no. 4, pp. 300-304.
Background: Long-term warfarin therapy requires intensive laboratory monitoring of venous blood. Reliable and efficient pointofcare testing (POCT) of capillary blood offers an alternative to laboratory monitoring. Aim: To explore the perceptions of health professionals to POCT in warfarin management and to identify the models of monitoring warfarinised patients preferred by health professionals. Method: An exploratory descriptive study that purposively sampled health professionals (hospital pharmacists, specialists, nurses, general practitioners) involved in the management of anticoagulated patients and practising within an area health service. Health professionals were invited to participate in a group discussion on POCT and to then complete a brief survey ranking proposed monitoring models incorporating POCT.
Vracar, D. & Bajorek, B. 2008, 'Australian general practitioners' views on pharmacist prescribing', Journal of Pharmacy Practice and Research, vol. 38, no. 2, pp. 96-102.
Aim: To explore Australian general practitioners views on extending prescribing rights to pharmacists, the appropriateness of pharmacist prescribing models, and the influence of general practitioners characteristics on their preference for a particular pharmacist prescribing model. Method: The study consisted of two parts. Part A was a scenario-based questionnaire using Likert-scale responses and Part B was a semi-structured interview. General practitioners were randomly recruited from two Sydney divisions of general practice. Data were analysed using descriptive statistics and qualitative responses were thematically analysed.

Khoo, A. & Bajorek, B. 2006, 'Extended roles for pharmacists in warfarin therapy: Identifying opportunities for pharmacist prescribing', Journal of Pharmacy Practice and Research, vol. 36, no. 3, pp. 190-193.
Background: Warfarin has traditionally posed a challenge to clinicians because ofits nan'ow therapeutic index. Extended roles for pharmacists may address some ofthe problems in warfarin management. International experience has involved anticoagulation clinics in which pharmacists have authority to engage in collaborative prescribing activities with physicians. Aim: To identify opportunities for pham1acist prescribing activities in warfarin management within the hospital setting. Method: Pham1acists from a Sydney teaching hospital were recruited. The first stage involved an audit of pharmacists' interventions in patients receiving warfarin. Stage two involved a focus group discussion to further explore these issues.
Hanes, C. & Bajorek, B. 2005, 'Pharmacist prescribing: Views of Australian hospital pharmacists', Journal of Pharmacy Practice and Research, vol. 35, no. 3, pp. 178-180.
Aim: To explore the views of a sample ofAustralian hospital pharmacists on prescribing privileges. Method: The study involved a questionnaire and a focus group discussion for hospital pharmacists and teacher practitioners. Participants could participate in either or both ofthese activities. Results: 15 pharmacists completed the questionnaire and 8 participated in the focus group discussion. Several models of pharmacist prescribing (discharge and specialist settings) were seen to be appropriate and useful to Australian practice. 93% ofpharmacists noted that prescribing privileges would enable them to provide more efficient/improved pharmaceutical care; 64% that prescribing would result in reduced healthcare costs; and all noted physician opposition as a barrier. Pharmacists indicated that they already prescribed on' an 'unofficial' basis. Training and accreditation beyond registration was deemed necessary by all pharmacists.

OBJECTIVES: To develop, implement, and evaluate a pharmacist-led multidisciplinary intervention in a hospital setting that would optimize antithrombotic use in elderly atrial fibrillation patients. The hypothesis that there would be an increase in the proportion of patients receiving antithrombotic therapy at discharge was tested. DESIGN: Evidence-based algorithms were developed to define the criteria (stroke risk vs contraindications) by which an elderly patients requirement for antithrombotic therapy was assessed. SETTING: A major Sydney teaching hospital. PARTICIPANTS: Two hundred eighteen consecutively admitted elderly patients (mean age 85.2) were recruited over a 6-month period.
Valiya, S. & Bajorek, B. 2005, 'Ximelagatran cost effectiveness for stroke prevention in atrial fibrillation', Journal of Pharmacy Practice and Research, vol. 35, no. 4, pp. 279-283.
Background: The benefit of warfarin for stroke prevention in non-valvular atrial fibrillation has been demonstrated in various clinical trials. Warfarin has a nan'ow therapeutic window and carries a significant risk ofbleeding. Ximelagatran is a new oral antithrombotic with predictable plasma concentrations and excellent bioavailability. Aim: To compare the costs and benefits of ximelagatran to that of warfarin and aspirin. Method: In a preliminary cost-effectiveness analysis, the costs and clinical consequences ofwarf31in, aspirin and ximelagatran were compared. The principal outcome was measured in the fonn of an incremental cost-effectiveness ratio. A decision analysis model was constructed to map the expected outcomes of three treatment alternatives. Sensitivity analysis tested the robustness of the data.
