Patients' Perspectives on Commencing Oral Anticoagulants in Atrial Fibrillation: An Exploratory Qualitative Descriptive Study. PHARMACY 2023; 11:153. [PMID: 37888498 PMCID: PMC10609834 DOI: 10.3390/pharmacy11050153] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/12/2023] [Revised: 09/20/2023] [Accepted: 09/21/2023] [Indexed: 10/28/2023] Open
Abstract
BACKGROUND Oral anticoagulants (OACs) are prescribed to patients with atrial fibrillation (AF) in order to lower stroke risk. However, patient refusal to commence OACs hinders effective anticoagulation. This study aimed to explore barriers and facilitators to patient agreement to commence OACs from the perspectives of patients with AF attending Australian general practices. METHODS A qualitative descriptive study utilising semi-structured individual interviews was conducted from March to July 2022. RESULTS Ten patients (60% male, median age = 78.5 years) completed interviews. Patients' passive roles in decision-making were identified as a facilitator. Other prominent facilitators included doctors explaining adequately and aligning their recommendations with patients' overall health goals, including the prevention of stroke and associated disabilities, and a clear understanding of the pros and cons of taking OACs. Reportedly insufficient explanation from doctors and the inconvenience associated with taking warfarin were identified as potential barriers. CONCLUSION Addressing factors that influence patient agreement to commence OACs should be an essential aspect of quality improvement interventions. Subsequent studies should also delve into the perspectives of eligible patients with AF who choose not to commence OACs as well as the perspectives of both patients and doctors regarding the decision to continue OAC treatment.

Efficacy and safety of sodium glucose cotransporter 2 inhibitors plus standard care in diabetic kidney disease: A systematic review and meta-analysis. J Diabetes Complications 2023; 37:108456. [PMID: 37127001 DOI: 10.1016/j.jdiacomp.2023.108456] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 10/28/2022] [Revised: 03/13/2023] [Accepted: 03/14/2023] [Indexed: 03/19/2023]
Abstract
INTRODUCTION Many people with type 2 diabetes progress to end-stage diabetic kidney disease (DKD) despite blockade of the renin-angiotensin system, suggesting the need for innovative treatment options for DKD. To capture the findings of recent studies, we performed an updated systematic review and meta-analysis of the efficacy and safety of sodium glucose co-transporter 2 (SGLT2) inhibitors combined with standard care involving angiotensin converting enzyme (ACE) inhibitors and/or angiotensin receptor blockers (ARBs) on the development and progression of DKD in people with type 2 diabetes compared with standard care alone. METHODS The Cochrane Library, MEDLINE, EMBASE, PubMed and clinical trials registers were systematically searched for randomized controlled trials published before 1 September 2022. Primary outcomes were urine albumin-creatinine ratio (UACR) and estimated glomerular filtration rate (eGFR). Secondary outcomes were glycated hemoglobin (HbA1c) and systolic blood pressure (SBP). Relative risk was calculated for adverse events. RESULTS Eight studies enrolling 5512 participants were included. In the meta-analysis (n = 1327), SGLT2 inhibitors were associated with a statistically significant reduction in UACR (weighted mean difference [WMD] -105.61 mg/g, 95 % CI -197.25 to -13.98, I2 = 99 %, p = 0.02). There was no statistically significant difference in relation to eGFR (n = 1375; WMD -0.23 mL/min/1.73m2, 95 % CI -4.34 to 3.89, I2 = 94 %, p = 0.91). CONCLUSIONS SGLT2 inhibitors in addition to standard care including ACE inhibitors and/or ARBs significantly reduced albuminuria, HbA1c and SBP when compared to standard care alone, supporting their routine use in people with type 2 diabetes.

Developing community pharmacists' role in the management of type 2 diabetes and related microvascular complications: a nationwide survey in Australia. PeerJ 2023; 11:e14849. [PMID: 36811008 PMCID: PMC9939021 DOI: 10.7717/peerj.14849] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/13/2022] [Accepted: 01/12/2023] [Indexed: 02/18/2023] Open
Abstract
Background Community pharmacists have regular interactions with people living with type 2 diabetes to supply medications, and have a potential role in supporting other primary care professionals in the screening, management, monitoring and facilitation of timely referral of microvascular complications. This study aimed to investigate the contemporary and future roles of community pharmacists in diabetes-related microvascular complication management. Methods This study involved an online Australian nation-wide survey of pharmacists administered via Qualtrics® and distributed through social media platforms, state and national pharmacy organisations, and via major banner groups. Descriptive analyses were undertaken using SPSS. Results Among 77 valid responses, 72% of pharmacists already provided blood pressure and blood glucose monitoring services for the management of type 2 diabetes. Only 14% reported providing specific microvascular complication services. Over 80% identified a need for a comprehensive microvascular complication monitoring and referral service, and agreed it is feasible and within the scope of practice of a pharmacist. Almost all respondents agreed that they would implement and provide a monitoring and referral service if provided with appropriate training and resources. Potential barriers to service implementation were competing demands and lack of remuneration and awareness among consumers and health professionals. Conclusions Type 2 diabetes services in Australian community pharmacies do not currently focus on microvascular complication management. There appears to be strong support for implementing a novel screening, monitoring and referral service via community pharmacy to facilitate timely access to care. Successful implementation would require additional pharmacist training, and identification of efficient pathways for service integration and remuneration.

Use of thromboprophylaxis guidelines and risk stratification tools in atrial fibrillation: A survey of general practitioners in Australia. J Eval Clin Pract 2022; 28:483-492. [PMID: 35385183 PMCID: PMC9324914 DOI: 10.1111/jep.13685] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 12/22/2021] [Revised: 03/16/2022] [Accepted: 03/23/2022] [Indexed: 11/28/2022]
Abstract
RATIONALE AND OBJECTIVES Clinical guidelines produced by cardiology societies (henceforth referred to simply as 'clinical guidelines') recommend thromboprophylaxis with oral anticoagulants (OACs) in patients with atrial fibrillation (AF) who have moderate-to-high stroke risk. However, deviations from these recommendations are observed, especially in the primary healthcare setting. The primary aims of this study were to evaluate the self-reported use of AF clinical guidelines and risk stratification tools among Australian general practitioners (GPs), and their perceptions regarding the available resources. METHOD We conducted an online survey of Australian GPs. Descriptive statistics were used to summarise the findings. RESULTS Responses from 115 GPs were included for analysis. Respondents reported various ways of accessing thromboprophylaxis-related information (n = 113), including clinical guidelines (13.3%), 'Therapeutic Guidelines© ' (37.2%) and Royal Australian College of General Practitioners websites (16.8%). Of those who reported reasons against accessing information from clinical guidelines (n = 97), the most frequent issues were: too many AF guidelines to choose from (34.0%; 33/97), different guidelines for different diseases (32.0%; 31/97), time-consuming to read guidelines (21.6%; 21/97), disagreements between different guideline recommendations (20.0%; 19/97), conflict with criteria for government subsidy (17.5%; 17/97) and GPs' busy schedules (15.5%; 15/97). When assessing patients' risk of stroke (n = 112) and bleeding (n = 111), the majority of the respondents reported primarily relying on a formal stroke risk (67.0%) and bleeding risk (55.0%) assessment tools, respectively. Respondents reported using formal stroke and bleeding risk assessment tools mainly when newly initiating patients on therapy (72.4%; 76/105 and 65.3%; 65/101, respectively). CONCLUSION Among our small sample of Australian GPs, most did not access thromboprophylaxis-related information directly from AF-specific clinical guidelines developed by cardiology societies. Although the majority reported using formal stroke and bleeding assessment tools, these were typically used on OAC initiation only. More focus is needed on formal risk reassessment as clinically indicated and at regular review.

Implementation factor mapping of a pilot study of point-of-care C-reactive protein testing for respiratory tract infections in community pharmacy. EXPLORATORY RESEARCH IN CLINICAL AND SOCIAL PHARMACY 2022; 6:100147. [PMID: 35733607 PMCID: PMC9207564 DOI: 10.1016/j.rcsop.2022.100147] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/11/2021] [Revised: 04/29/2022] [Accepted: 05/26/2022] [Indexed: 11/06/2022] Open
Abstract
Background Explicit consideration of implementation factors in community pharmacy service development may facilitate widespread implementation and sustainability. Objectives This study involved mapping the methodology for the pilot study of point-of-care C-reactive protein (CRP) testing to support pharmacists' management of respiratory tract infections in Western Australian pharmacies against an implementation factor framework, focussing on the resources and training program provided to participating pharmacy staff. Methods Phase 1 involved post hoc mapping of the pilot study methodology against the framework previously described by Garcia-Cardenas et al.; phase 2 was an a priori evaluation of the resources and training program, involving pre-training, post-training, and post-pilot questionnaires administered to pharmacists and pharmacy assistants/interns. A mixed model analysis compared pharmacists' responses at the three time points. Results Employment of comprehensive strategies to optimise service feasibility and sustainability was demonstrated across the five domains of ‘professional service’, ‘pharmacy staff’, ‘pharmacy’, ‘local environment’ and ‘system’; further consideration of ‘consumer’ or ‘patient’ factors is needed to address issues such as patient refusal. Study pharmacists (n = 10) and pharmacy assistants/interns (n = 5) reported high levels of satisfaction with the training (100% ‘good’/‘excellent’). Pharmacists reported significantly improved attitudes towards, confidence in, and knowledge about CRP testing and service provision from pre- to post-training (p < 0.05). Positive perceptions were maintained at the post-pilot time point. Conclusions Post hoc mapping of implementation factors highlighted potential strengths and deficiencies of the current service model. Systematic, prospective mapping, coupled with strategies to explicitly emphasise the patient perspective, may have value in optimising service implementation or modifying future service delivery models.

Point-of-care C-reactive protein testing service for respiratory tract infections in community pharmacy: a qualitative study of service uptake and experience of pharmacists. Int J Clin Pharm 2022; 44:466-479.

Abstract
Background Targeted interventions in community pharmacies, such as point-of-care C-reactive protein testing, could reduce inappropriate antimicrobial consumption in patients presenting with symptoms of respiratory tract infections, although data regarding Australian pharmacists’ perspectives on its provision are limited. Aim To explore pharmacists’ experiences and perspectives of point-of-care C-reactive protein testing, including barriers and facilitators, influencing service provision and uptake. Method A point-of-care C-reactive protein testing service for patients presenting with respiratory tract infection symptoms was trialled in five purposively selected community pharmacies in metropolitan Western Australia. Two pharmacists from each pharmacy participated in one-to-one semi-structured telephone interviews, regarding pharmacist demographics, pharmacy characteristics, experience with the point-of-care C-reactive protein service and training/resources. Interviews were audio-recorded and transcribed. Data were imported into NVivo for thematic analysis. Results Interview durations ranged from 28.2 to 60.2 min (mean: 50.7 ± 10.2 min). Of the five themes which emerged, participants reported the point-of-care C-reactive protein testing was simple, fast, reliable and accurate, assisted their clinical decision-making and contributed to antimicrobial stewardship. A major factor facilitating service provision and uptake by consumers was the accessibility and credibility of pharmacists. Barriers included time constraints and heavy documentation. Participants believed there was a public demand for the service. Conclusion Given the global antimicrobial resistance crisis, pharmacists have an important role in minimising the inappropriate use of antimicrobials. The point-of-care C-reactive protein service was readily accepted by the public when offered. However, ensuring efficient service delivery and adequate remuneration are essential for its successful implementation.

Abstract
BACKGROUND Integration of clinical pharmacists into multidisciplinary Mental Health Hospital-in-the-Home teams is increasing but little is known about the medication safety contribution these pharmacists make. AIM To evaluate whether clinical pharmacist involvement in a Mental Health Hospital-in-the-Home service improved medication safety key performance indicators. METHOD Medical records were retrospectively reviewed of all patients admitted to 2 Western Australian Mental Health Hospital-in-the-Home services from September to November 2015. SITE 1: was a 16-bed service incorporating a clinical pharmacist as part of its multidisciplinary team. SITE 2: was a similarly structured 18-bed service but without clinical pharmacist involvement. The primary outcome measure was completion of medication safety key performance indicators obtained from the Western Australian Government Pharmaceutical Review Policy and mental health-specific best practice guidelines. RESULTS Key performance indicators from Site 1 (n = 75 records), which incorporated a clinical pharmacist, demonstrated significantly (p < 0.001) higher rates of completion of medication reconciliation [65 (87%) versus 17 (29%)], accurate adverse drug reaction list [73 (97%) versus 34 (58%)], accurate discharge medication list [51 (74%) versus 18 (45%)], accurate medication profile [74 (99%) versus 40 (68%)] and medication chart review [74 (99%) versus 0 (0%)] than Site 2 (n = 59). CONCLUSION Integrating a clinical pharmacist into a Mental Health Hospital-in-the-Home program significantly improved achievement of medication safety key performance indicators.

Abstract
Objective This study investigated antibiotic prophylaxis (AP) guideline adherence and the cardiac implantable electronic device (CIED) infection rate in two major Australian public teaching hospitals. Methods In a retrospective observational study, the medical records of patients who underwent CIED procedures between January and December 2017 were reviewed (Hospital A, n = 400 procedures; Hospital B, n = 198 procedures). Adherence to AP guidelines was assessed regarding drug, dose, timing, route and frequency. Infection was identified using follow-up documentation. Results AP was administered in 582 of 598 procedures (97.3%). Full guideline adherence was observed in 33.9% of procedures (203/598) and differed significantly between Hospitals A and B (47.3% vs 7.1%, respectively; P < 0.001). Common reasons for non-adherence were the timing of administration (42.3% vs 60.6% non-adherent in Hospitals A and B, respectively; P < 0.001) and repeat dosing (19.3% vs 78.8% non-adherent in Hospitals A and B, respectively; P < 0.001). Twenty infections were identified over 626.6 patient-years of follow-up (mean (±s.d.) follow-up 1.0 ± 0.3 years). The infection rate was 3.19 per 100 patient-years (P = 0.99 between hospitals). Two devices were removed due to infection; no patients died from CIED infection. Conclusions Although the rate of serious CIED infection was low, there was evidence of highly variable and suboptimal antibiotic use, and potential overuse of AP. What is known about the topic? Previous Australian studies have revealed high rates of inappropriate surgical AP. CIED infections are potentially life threatening, but can be avoided through effective use of AP. However, prolonged durations of AP in this setting may also result in complications, including Clostridioides difficile infection. What does this paper add? This study, the first to our knowledge to focus specifically on adherence to Australian guidelines for AP in CIED procedures, highlighted several common issues between AP in this setting and surgical and procedural AP more broadly. 'Early' and 'late' dose administration and extended post-procedural AP were common. Only 34% of prescriptions fully adhered to the guidelines; practices varied significantly between the two hospitals. What are the implications for practitioners? There is a clear need for institution-specific antimicrobial stewardship strategies to optimise AP in CIED procedures, aligned with the Antimicrobial Stewardship Clinical Care Standard. Patients are being placed at potentially avoidable risk of both complications of extended durations of AP and CIED infection, although the rate of serious CIED infection was low. A standardised approach to surveillance of CIED infections and prospective multisite audits of AP in CIED procedures using a validated tool, such as the Surgical National Antimicrobial Prescribing Survey, are recommended to better inform evidence-based practice. Potential strategies to optimise guideline adherence include prescribing support in patients with immediate penicillin hypersensitivity or methicillin-resistant Staphylococcus aureus colonisation, optimising the in-patient location of drug administration to promote timely dosing, limiting inappropriate post-procedural prophylaxis and routine S. aureus screening and decolonisation.

Abstract
BACKGROUND Clinical guidelines on atrial fibrillation management help optimize the use of oral anticoagulants. However, guideline non-adherence is common, particularly in the primary care setting. The primary aim of this systematic review was to identify effective strategies for improving adherence to guideline-directed thromboprophylaxis to patients with atrial fibrillation in the primary care setting. METHODS A search was conducted on 6 electronic databases (Medline, Embase, ScienceDirect, Scopus, the Cumulative Indexing of Nursing and Allied Health Literature, and Web of Science) supplemented by a Google advanced search. Studies aimed at improving oral thromboprophylaxis guideline adherence in patients with atrial fibrillation, in the primary care setting, were included in the study. RESULTS A total of 33 studies were included in this review. Nine studies employed electronic decision support (EDS), of which 4 reported modest improvements in guideline adherence. Five of 6 studies that utilized local guidelines as quality improvement measures reported improvement in guideline adherence. All 5 studies that employed coordinated care and the use of specialist support and 4 of the 5 studies that involved pharmacist-led interventions reported improvements in guideline adherence. Interventions based mainly on feedback from audits were less effective. CONCLUSIONS Multifaceted interventions, especially those incorporating coordinated care and specialist support, pharmacists, or local adaptations to and implementation of national and/or international guidelines appear to be more consistently effective in improving guideline adherence in the primary care setting than interventions based mainly on EDS and feedback from audits.

Abstract
Atrial fibrillation is the most common arrhythmia. It increases the risk of thromboembolism by up to fivefold. Guidelines provide evidence-based recommendations to effectively mitigate thromboembolic events using oral anticoagulants while minimizing the risk of bleeding. This review focuses on non-adherence to contemporary guidelines and the factors associated with guideline non-adherence. The extent of guideline non-adherence differs according to geographic region, healthcare setting, and risk stratification tools used. Guideline adherence has gradually improved over recent years, but a significant proportion of patients are still not receiving guideline-recommended therapy. Physician-related and patient-related factors (such as patient refusals, bleeding risk, older age, and recurrent falls) also contribute to guideline non-adherence, especially to undertreatment. Quality improvement initiatives that focus on undertreatment, especially in the primary healthcare setting, may help to improve guideline adherence.

Abstract
The global prevalence of diabetic kidney disease is rapidly accelerating due to an increasing number of people living with type 2 diabetes. It has become a significant global problem, increasing human and financial pressures on already overburdened healthcare systems. Interest in diabetic kidney disease has increased over the last decade and progress has been made in determining the pathogenic mechanisms and patient-related factors involved in the development and pathogenesis of this disease. A greater understanding of these factors will catalyse the development of novel treatments and influence current practice. This review summarises the latest evidence for the factors involved in the development and progression of diabetic kidney disease, which will inform better management strategies targeting such factors to improve therapeutic outcomes in patients living with diabetes.

A qualitative exploration of factors contributing to non-guideline adherent antipsychotic polypharmacy. Res Social Adm Pharm 2021; 18:2457-2467.

Abstract
BACKGROUND Antipsychotic polypharmacy ("polypharmacy") involves the concurrent prescribing of two or more antipsychotics for managing schizophrenia. It occurs frequently despite there being limited clinical evidence for this practice and an increased risk of adverse events. Little is understood about why it occurs outside of treatment guidelines, highlighting a current research gap. OBJECTIVE To explore the factors contributing to non-evidence based polypharmacy practice and possible strategies for addressing these factors. METHODS Three focus groups were conducted between June and August 2018 with doctors and nurses employed at a mental health unit of a Western Australian public hospital. Participants were asked about their perceptions of polypharmacy, why it occurred and what could limit its prevalence. Thematic inductive analysis was mapped to the Theoretical Domains Framework to identify key underlying themes and to establish potential enablers and barriers for practice change. RESULTS Participants understood the risks of polypharmacy and perceived it to largely be perpetuated by external factors, out of which two key themes emerged: system-related issues (e.g.: communication failures whereby de-prescribing plans are not actioned); and patient-related issues (e.g.: misinformed views translating to medication-seeking behaviour). This led to the third theme: a disconnect between clinicians' knowledge and their practices (i.e.: being aware of Australian evidence-based guideline recommendations yet acknowledging polypharmacy still occurred due to the aforementioned issues). Strategies suggested to address these issues included developing medication management plans to bridge communication gaps and managing patients' medication expectations with education. CONCLUSIONS Management of schizophrenia is complex, requiring consideration of many patient-related and systemic factors. Polypharmacy has a place in certain contexts, however, must be well considered and closely monitored to allow for early identification of opportunities to rationalise (i.e.: de-prescribe) therapy, where appropriate. Future research objectives will centre on implementing strategies identified from these focus groups to optimise patient outcomes.

Abstract
BACKGROUND Point-of-care (POC) C-reactive protein (CRP) testing is employed in European primary care settings to differentiate viral from bacterial respiratory tract infections (RTIs) the latter, requiring referral for antibiotics. This service has yet to be trialled in Australian community pharmacy to support over-the-counter RTI management. OBJECTIVES To evaluate the feasibility, based on clinical and operational outcomes, of POC CRP testing to support Western Australian community pharmacists' management of RTIs. METHODS Patients with RTI signs and symptoms were recruited from June-August 2019 at 5 community pharmacies. Trained pharmacists made recommendations based on participants' POC CRP levels and routine clinical assessment. Participants completed questionnaires and telephone follow-ups on Days 3 (by pharmacists) and 5 (by researchers) post-testing. Service provision and uptake were assessed in 3 separate weekly tally sheets. RESULTS Clinical outcomes: CRP levels among the 131 participants recruited were: < 5 mg/L (bacterial infection unlikely; n = 60; 45.8%); 5-19 mg/L (bacterial infection possible if suggestive routine assessment; n = 52; 39.7%) and 20-100 mg/L (bacterial infection likely if suggestive routine assessment; n = 19; 14.5%). Pharmacists' management included over-the-counter medicines (131, 100%), self-care advice (125, 95.4%) and immediate general practitioner (GP) referral (15, 11.5%). Sixty-five percent (76/117) of participants had recovered by Day 5. Operational outcomes: The services was provided in 21.2% of eligible RTI presentations, representing a service uptake rate of 28.1%. Post-CRP testing, 50.9% (58/114) of participants had changed perceptions regarding their need for antibiotics, with 14.3% (16/112) subsequently intending to seek a GP prescription. Consumer satisfaction was high (100%) and most participants (93.4%, 123/131) would utilise the service again. CONCLUSIONS POC CRP testing was a feasible and well-accepted strategy to facilitate community pharmacy as a triage point for RTI. Consumer confidence in the pharmacists' advice, supported by CRP testing, potentially reduced unnecessary GP visits and antibiotic prescribing.

The Quality of Advice Provided by Pharmacists to Patients Taking Direct Oral Anticoagulants: A Mystery Shopper Study. PHARMACY 2020; 8:pharmacy8030164. [PMID: 32899401 PMCID: PMC7559353 DOI: 10.3390/pharmacy8030164] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/03/2020] [Revised: 08/25/2020] [Accepted: 08/25/2020] [Indexed: 11/21/2022] Open
Abstract
Pharmacists report being less confident in their knowledge of direct acting oral anticoagulants (DOACs) than of vitamin K antagonists, which may influence their ability to detect and manage complications arising from DOAC use. In a mystery shopper study, patient agents were sent into community pharmacies with symptom or product-related requests related to common complications that might arise during treatment with oral anticoagulants, with each visit being assessed for the preferred outcome. Only 10/41 (24.4%) visits resulted in the preferred outcome. A complete history-taking process, obtaining a medical history, patient characteristics and pharmacist involvement were strong predictors of the preferred outcome being achieved. The preferred outcome was not consistently achieved without pharmacist involvement. The potential for strategies that support comprehensive pharmacist involvement in over-the-counter requests should be considered to ensure the provision of optimal care to patients taking high-risk medications such as DOACs.

Evaluation of calling criteria for the rapid response system utilising single versus multiple physiological parameter disturbances. Intern Med J 2020; 51:1117-1125. [PMID: 32388901 DOI: 10.1111/imj.14893] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/30/2019] [Revised: 04/02/2020] [Accepted: 04/19/2020] [Indexed: 11/28/2022]
Abstract
BACKGROUND The Adult Deterioration Detection System for Medical Emergency Team (MET) activation is widely used and includes single parameter (SP-MET) and multiple parameter (MP-MET) disturbances. Whether the patient characteristics, interventions and outcomes differ for SP-MET compared with MP-MET is uncertain. AIMS To describe MET interventions and outcomes of SP versus MP MET in the Acute Medical Unit (AMU) of a tertiary care hospital. METHODS Retrospective audit over 6 months comparing SP-MET and MP-MET groups. RESULTS SP-MET constituted 64.1% (168) of 262 AMU MET calls, most commonly for hypotension (35.5%) and tachycardia (14.1%). There were no significant differences in demographic and disease characteristics between the two groups. Common interventions included fluid/electrolyte replacement in 139 (52%), oxygen therapy in 46 (17%) and non-invasive ventilation in 33 (13%) patients. After MET intervention, 82.4% patients stayed on the ward, 8.4% died/were palliated, 6.5% were transferred to the Intensive Care Unit (ICU) and 2.7% patients required urgent transfer to the theatre for intervention. SP-MET patients were more likely to remain on the ward (88.7% vs 71.3%; P = 0.001), receive ward-based interventions (85.1% vs 61.7%; P < 0.001) and less likely to experience death/palliation (4.2% vs 16%, P = 0.001) compared with the MP-MET group. MP-MET were independently associated with negative outcomes (OR 3.10; 95% CI 1.60-6.00). CONCLUSION SP-MET identify a cohort of patients at lower risk of requiring escalation of care and ICU admission. Given the resource intensity of MET activation, further research is warranted to determine whether alternative response strategies are appropriate for selected SP disturbances.

Abstract
Background: There are limited Australian data on sex differences in oral anticoagulant (OAC) prescribing in atrial fibrillation (AF) and ongoing debate regarding the optimal approach to stroke risk assessment and OAC prescribing in female patients with AF. Objective: The purpose of this study was to investigate sex differences in the prescribing of OACs in patients with AF stratified by stroke risk and in the rate of adverse outcomes. Methods: A retrospective analysis of patients admitted to the Royal Hobart Hospital (Tasmania, Australia) with nonvalvular AF between January 2011 and July 2015 was conducted. Rates of antithrombotic prescribing according to sex and stroke risk were assessed along with a multivariate analysis for predictors of OAC prescribing. Rates of thromboembolism, bleeding, and all-cause mortality were assessed according to sex. Results: A total of 2090 patients were included (44.7% female). Women with a CHA2DS2-VA score ≥2 were less likely to receive an OAC compared with men (56.7% vs 62.2%, P = 0.023). Female sex was an independent negative predictor of OAC prescribing (adjusted odds ratio = 0.83; 95% CI = 0.69-0.99; P = 0.041). There were no sex differences in the incidence rates of thromboembolism, bleeding, or all-cause mortality in patients newly commenced on antithrombotic therapy. Conclusion and Relevance: Female patients with a high stroke risk were less likely to receive guideline-recommended treatment. This study provides new information on prescribing trends within the Australian setting and highlights the opportunity to improve the management of female patients with AF and 1 or more additional stroke risk factors.

Abstract
OBJECTIVE We tested the ability of a type 1 diabetes (T1D) genetic risk score (GRS) to predict progression of islet autoimmunity and T1D in at-risk individuals. RESEARCH DESIGN AND METHODS We studied the 1,244 TrialNet Pathway to Prevention study participants (T1D patients' relatives without diabetes and with one or more positive autoantibodies) who were genotyped with Illumina ImmunoChip (median [range] age at initial autoantibody determination 11.1 years [1.2-51.8], 48% male, 80.5% non-Hispanic white, median follow-up 5.4 years). Of 291 participants with a single positive autoantibody at screening, 157 converted to multiple autoantibody positivity and 55 developed diabetes. Of 953 participants with multiple positive autoantibodies at screening, 419 developed diabetes. We calculated the T1D GRS from 30 T1D-associated single nucleotide polymorphisms. We used multivariable Cox regression models, time-dependent receiver operating characteristic curves, and area under the curve (AUC) measures to evaluate prognostic utility of T1D GRS, age, sex, Diabetes Prevention Trial-Type 1 (DPT-1) Risk Score, positive autoantibody number or type, HLA DR3/DR4-DQ8 status, and race/ethnicity. We used recursive partitioning analyses to identify cut points in continuous variables. RESULTS Higher T1D GRS significantly increased the rate of progression to T1D adjusting for DPT-1 Risk Score, age, number of positive autoantibodies, sex, and ethnicity (hazard ratio [HR] 1.29 for a 0.05 increase, 95% CI 1.06-1.6; P = 0.011). Progression to T1D was best predicted by a combined model with GRS, number of positive autoantibodies, DPT-1 Risk Score, and age (7-year time-integrated AUC = 0.79, 5-year AUC = 0.73). Higher GRS was significantly associated with increased progression rate from single to multiple positive autoantibodies after adjusting for age, autoantibody type, ethnicity, and sex (HR 2.27 for GRS >0.295, 95% CI 1.47-3.51; P = 0.0002). CONCLUSIONS The T1D GRS independently predicts progression to T1D and improves prediction along T1D stages in autoantibody-positive relatives.

Abstract
WHAT IS KNOWN AND OBJECTIVE Adverse drug reactions (ADRs) are an important cause of mortality during medical care. To our knowledge, no Ethiopian studies have reported on mortality due to ADRs in patients presenting to hospital from the community setting. The aim of this study was to determine the mortality rate attributable to ADRs in patients presenting to hospital, identify drugs implicated in the ADR-related deaths and identify factors contributing to ADR-related mortality at Jimma University Specialised Hospital (JUSH), south-west Ethiopia METHODS: This cross-sectional study included 1001 patients aged ≥18 years consecutively admitted to medical wards from May 2015 to August 2016. ADR-related mortality was determined through detailed review of medical records, laboratory tests and patient interviews followed by causality assessment by the Naranjo algorithm and expert consensus. RESULTS Of 1001 patients, 15, 1.5% (95% confidence interval [CI]: 0.80%-2.30%) died with an ADR. The primary suspected causes of death were drug-induced hepatotoxicity (7, 43.8%) followed by acute kidney injury (4, 25.0%). Isoniazid (6, 33.3%), pyrazinamide (3, 16.7%), efavirenz (2, 11.1%) and tenofovir (2, 11.1%) were commonly implicated drugs. The majority of ADRs (14, 93.8%) were preventable. Unadjusted bivariate comparisons suggested patients who died with ADRs were more likely to have pre-existing liver disease (40.0% vs 7.0%; 95% confidence interval [CI]: 8.1%-57.8%), a history of ADRs (40% vs 1.4%; 95% CI: 13.8%-63.4%), a lower mean (±SD) body mass index (BMI, 17.6 ± 2.1 vs 20.0 ± 2.9 kg/m2 ; 95% CI = 0.9-3.9), exposure to antitubercular (46.7% vs 18.9%; 95% CI: 2.3%-53.1%) and antiretroviral (40.0% vs 7.7%; 95% CI: 7.5%-57.2%) therapies, and a higher mean number of medications (7.1 ± 3.3 vs 3.8 ± 2.1; 95% CI: 2.2-4.4) and Charlson Comorbidity Index (3.9 ± 2.9 vs 1.6 ± 1.8; 95% CI: 1.4-3.2) than surviving patients without ADRs. WHAT IS NEW AND CONCLUSION Fatal ADRs were common in patients presenting to hospital. The drugs implicated were mostly antitubercular and antiretroviral therapies, reflecting the high burden of HIV and tuberculosis in the study population. ADR-related deaths were significantly associated with poor nutritional status. The majority of ADR-related deaths were preventable, highlighting the need to develop a multidisciplinary approach to closely monitor patients who are prescribed antitubercular and antiretroviral therapies, particularly in patients with hepatic disease, a history of ADRs, who are malnourished and who are exposed to multiple medications.

Abstract
Background: The aim of this study was to investigate the proportion of patients who have suboptimal adherence to oral anticoagulant (OAC), identify the predictors of adherence, and determine whether patient-related factors vary across adherence levels in Australia. Methods: Respondents were recruited for an online survey using Facebook. Survey instruments included the Morisky Medication Adherence Scale, the Anticoagulation Knowledge Tool, the Perception of Anticoagulant Treatment Questionnaires, and a modified Cancer Information Overload scale. Predictors of medication adherence were identified using ordinal regression analysis. Results: Of the 386 responses eligible for analysis, only 54.9% reported a high level of adherence. Participants aged 65 years or younger were less likely to have high adherence compared to older participants (odds ratio [OR], 0.54; 95% confidence interval [CI], 0.33-0.88; P = .013), while females were more likely to be highly adherent compared to males (OR, 1.69; 95% CI, 1.08-2.64; P = .023). The analyses showed that age, gender, treatment satisfaction, information overload, concerns about making mistake when taking OACs, and cost of medication were significant predictors of adherence. Conclusion: Self-reported suboptimal adherence to OAC is common among patients with atrial fibrillation. A focus on supporting people who are at higher risk of suboptimal adherence is needed to maximize the benefit of OAC therapy in this population.

Abstract
BACKGROUND Although utilization of anticoagulation in patients with atrial fibrillation (AF) has increased in recent years, contemporary data regarding thromboembolism and mortality incidence rates are limited outside of clinical trials. This study aimed to investigate the impact of the direct oral anticoagulants (DOACs) on the clinical outcomes of patients with AF included in the Tasmanian Atrial Fibrillation Study. METHODS The medical records of all patients with a primary or secondary diagnosis of AF who presented to public hospitals in Tasmania, Australia, between 2011 and 2015, were retrospectively reviewed. We investigated overall thromboembolic events (TEs), ischemic stroke/transient ischemic attack (IS/TIA), and mortality incidence rates in patients admitted to the Royal Hobart Hospital, the main teaching hospital in the state. We compared outcomes in 2 time periods: prior to the availability of DOACs (pre-DOAC; 2011 to mid-2013) and following their general availability after government subsidization (post-DOAC; mid-2013 to 2015). RESULTS Of the 2390 patients with AF admitted during the overall study period, 942 patients newly prescribed an antithrombotic medication (465 and 477 from the pre-DOAC and post-DOAC time periods, respectively) were followed. We observed a significant decrease in the incidence rates of overall TE (3.2 vs 1.7 per 100 patient-years [PY]; P < .001) and IS/TIA (2.1 vs 1.3 per 100 PY; P = .022) in the post-DOAC compared to the pre-DOAC period. All-cause mortality was significantly lower in the post-DOAC period (2.9 vs 2.2 per 100 PY, P = .028). Increasing age, prior stroke, and admission in the pre-DOAC era were all risk factors for TE, IS/TIA, and mortality in this study population. The risk of IS/TIA was more than doubled (hazard ratio: 2.54; 95% confidence interval: 1.17-5.52) in current smokers compared to ex- and nonsmokers. CONCLUSION Thromboembolic event and all-cause mortality rates were lower following the widespread availability of DOACs in this population.

Abstract
INTRODUCTION Adverse drug reactions (ADRs) have been commonly cited as a major cause of hospital admissions in older individuals. However, despite the apparent magnitude of this problem, there are limited prospective data on ADRs as a cause of hospitalization in elderly medical patients. OBJECTIVES The objective of this study was to evaluate the proportion, clinical characteristics, causality, severity, preventability, and outcome of ADR-related admissions in older patients admitted to two Tasmanian hospitals. METHODS We conducted a prospective cross-sectional study at the Royal Hobart and Launceston General Hospitals in Tasmania, Australia. A convenience sample of patients, aged 65 years and older, undergoing unplanned overnight medical admissions was screened. ADR-related admissions were determined through expert consensus from detailed review of medical records and patient interviews. The causality, preventability and severity of each ADR-related admission were assessed. RESULTS Of 1008 admissions, the proportion of potential ADR-related medical admissions was 18.9%. Most (88.5%) ADR-related admissions were considered preventable. Cardiovascular complaints (29.3%) represented the most common ADRs, followed by neuropsychiatric (20.0%) and renal and genitourinary disorders (15.2%). The most frequently implicated drug classes were diuretics (23.9%), agents acting on the renin angiotensin system (16.4%), β-blocking agents (7.1%), antidepressants (6.9%), and antithrombotic agents (6.9%). Application of the Naranjo algorithm found 5.8% definite, 70.1% probable, and 24.1% possible ADRs. ADR severity was rated moderate and severe in 97.9% and 2.1% of admissions, respectively. For most (93.2%) ADR-related admissions the ADR resolved and the patient recovered. CONCLUSION Hospitalization due to an ADR is a common occurrence in this older population. There is need for future studies to implement and evaluate interventions to reduce the risk of ADR-related admissions in elderly populations.

Abstract
BACKGROUND Adverse drug reactions are a major cause of hospital admissions in older individuals, with the majority potentially preventable. Despite the apparent magnitude of this problem, little is known about rates of repeat admission to hospital as a result of adverse drug reactions. OBJECTIVES The objectives of this study were to investigate the occurrence of repeat adverse drug reaction-related hospital admissions in elderly patients within 12 months of an adverse drug reaction-related admission to a medical ward and whether a validated adverse drug reaction score could be useful in identifying patients at higher risk of a repeat adverse drug reaction-related hospitalisation. METHODS This retrospective study followed elderly participants who were hospitalised with an adverse drug reaction from our earlier study [the PADR-EC (Prediction of Hospitalization due to Adverse Drug Reactions in Elderly Community-Dwelling Patients) study] to identify repeat adverse drug reaction-related hospital admissions within 12 months of discharge. The PADR-EC score is the sum of points assigned to five significant predictors of adverse drug reaction-related hospitalisation: antihypertensive use, renal failure, dementia, inappropriate anticholinergic use and drug changes in the preceding 3 months. The causality, preventability and severity of each adverse drug reaction-related repeat admission within the 12-month follow-up were assessed. RESULTS Adverse drug reaction-related repeat admissions occurred after 13.4% (n = 15) of 112 adverse drug reaction-related index admissions. Patients with a repeat adverse drug reaction-related admission had significantly higher PADR-EC scores at discharge of their index admission (median PADR-EC score 7, interquartile range 7-9) than patients who were not readmitted (median PADR-EC score 7, interquartile range 5-7, p = 0.034). Most (73.3%) adverse drug reaction-related repeat admissions were considered 'preventable'. Adverse drug reaction severity was 'moderate' in all cases. Renal disorders (44.4%) represented the most common adverse drug reactions and the most frequently implicated drug classes were diuretics (44.8%). All adverse drug reaction-related repeat admissions were found to be 'probable'. CONCLUSIONS One in eight elderly patients hospitalised because of an adverse drug reaction had a repeat admission for an adverse drug reaction within 12 months of discharge. The PADR-EC score could potentially be used at hospital discharge to prioritise patients for interventions to prevent subsequent adverse drug reaction-related hospital admissions.

Abstract
BACKGROUND Atrial fibrillation (AF) is the most commonly diagnosed arrhythmia in clinical practice, and is associated with a significant medical and economic burden. Anticoagulants reduce the risk of stroke and systemic embolism by approximately two-thirds compared with no therapy. Knowledge regarding anticoagulant therapy can influence treatment outcomes in patients with AF. OBJECTIVE To measure the level of anticoagulation knowledge in patients with AF taking oral anticoagulants (OACs), investigate the association between patient-related factors and anticoagulation knowledge, and compare these results in patients taking warfarin and direct-acting oral anticoagulant (DOACs). METHODS Participants were recruited for an online survey via Facebook. Survey components included the Anticoagulation Knowledge Tool, the Perception of Anticoagulant Treatment Questionnaires (assessing treatment expectations, convenience and satisfaction), a modified Cancer Information Overload scale and the Morisky Medication Adherence Scale. Treatment groups were compared and predictors of OAC knowledge were identified. RESULTS Participants taking warfarin had a higher knowledge score compared with those taking DOACs (n = 386, 73% ± 13% vs 66% ± 14%, P<.001). Advancing age, type of OAC, health information overload and ease of OAC use (treatment expectation) were significant predictors of knowledge. Treatment expectation, including the belief that OAC treatment would cause bleeding side effects, varied significantly between participants taking warfarin and DOACs (P = .011). CONCLUSION The study identified knowledge gaps in patients taking OACs, and these deficiencies appeared to be greater in participants taking DOACs. Knowledge assessment should be integrated into patient counselling sessions to help identify and resolve knowledge deficits.

Abstract
Adverse drug reactions (ADRs) are one of the leading causes of hospital admissions and morbidity in developed countries and represent a substantial burden on healthcare delivery systems. However, there is little data available from low- and middle-income countries. This review compares the prevalence and characteristics of ADR-related hospitalisations in adults in developed and developing countries, including the mortality, severity and preventability associated with these events, commonly implicated drugs and contributing factors. A literature search was conducted via PubMed, Scopus, Web of Science, Embase, ProQuest and Google Scholar to find articles published in English from 2000 to 2015. Relevant observational studies were included. The median (with interquartile range [IQR]) prevalence of ADR-related hospitalisation in developed and developing countries was 6.3 % (3.3-11.0) and 5.5 % (1.1-16.9), respectively. The median proportions of preventable ADRs in developed and developing countries were 71.7 % (62.3-80.0) and 59.6 % (51.5-79.6), respectively. Similarly, the median proportions of ADRs resulting in mortality in developed and developing countries were 1.7 % (0.7-4.8) and 1.8 % (0.8-8.0), respectively. Commonly implicated drugs in both settings were antithrombotic, non-steroidal anti-inflammatory and cardiovascular drugs. Older age, female gender, number of medications, renal impairment and heart failure were reported to be associated with an increased risk for ADR-related hospitalisation in both settings while HIV/AIDS was implicated in developing countries only. The majority of ADRs were preventable in both settings, highlighting the importance of improving medication use, particularly in vulnerable patient groups such as the elderly, patients with multiple comorbidities and, in developing countries, patients with HIV/AIDS.

Abstract
BACKGROUND Adverse drug reactions (ADRs) are important causes of morbidity and mortality in the healthcare system; however, there are no studies reporting on the magnitude and risk factors associated with ADR-related hospitalisation in Ethiopia. OBJECTIVES To characterise the reaction types and the drugs implicated in admission to Jimma University Specialized Hospital, Southwest Ethiopia, and to identify risk factors associated with ADR-related hospitalisation. METHODS A prospective cross-sectional study was conducted from May 2015 to August 2016 among consenting patients aged ≥18 years consecutively admitted to medical wards taking at least one medication prior to admission. ADR-related hospitalisations were determined through expert review of medical records, laboratory tests, patient interviews and physical observation. ADR causality was assessed by the Naranjo algorithm followed by consensus review with internal medicine specialist. ADR preventability was assessed using Schumock and Thornton's criteria. Only definite and probable ADRs that provoked hospitalisation were considered. Binary logistic regression was used to identify independent predictors of ADR-related hospitalisation. RESULTS Of 1,001 patients, 103 (10.3%) had ADR-related admissions. Common ADRs responsible for hospitalisation were hepatotoxicity (35, 29.4%) and acute kidney injury (27, 22.7%). The drug classes most frequently implicated were antitubercular agents (45, 25.0%) followed by antivirals (22, 12.2%) and diuretics (19, 10.6%). Independent predictors of ADR-related hospitalisation were body mass index (BMI) <18.5 kg/m2 (adjusted odd ratio [AOR] = 1.69; 95% confidence interval [CI] = 1.10-2.62; p = 0.047), pre-existing renal disease (AOR = 2.84; 95%CI = 1.38-5.85, p = 0.004), pre-existing liver disease (AOR = 2.61; 95%CI = 1.38-4.96; p = 0.003), number of comorbidities ≥4 (AOR = 2.09; 95%CI = 1.27-3.44; p = 0.004), number of drugs ≥6 (AOR = 2.02; 95%CI = 1.26-3.25; p = 0.004) and history of previous ADRs (AOR = 24.27; 95%CI = 11.29-52.17; p<0.001). Most ADRs (106, 89.1%) were preventable. CONCLUSIONS ADRs were a common cause of hospitalisation. The majority of ADRs were preventable, highlighting the need for monitoring and review of patients with lower BMI, ADR history, renal and liver diseases, multiple comorbidities and medications. ADR predictors should be integrated into clinical pathways and pharmacovigilance systems.

Changes in Oral Anticoagulant Prescribing for Stroke Prevention in Patients With Atrial Fibrillation. Am J Cardiol 2017; 120:1133-1138. [PMID: 28781025 DOI: 10.1016/j.amjcard.2017.06.055] [Citation(s) in RCA: 25] [Impact Index Per Article: 3.6] [Reference Citation Analysis] [Abstract] [MESH Headings] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 04/15/2017] [Revised: 06/03/2017] [Accepted: 06/20/2017] [Indexed: 11/17/2022]
Abstract
Suboptimal guideline adherence and underuse of anticoagulants in patients with atrial fibrillation (AF) have been reported worldwide. This study aimed to compare anticoagulation practice in Australia during the pre- and postdirect oral anticoagulant (DOAC) eras. Between January 2011 and July 2015, patients with nonvalvular AF (NVAF) admitted to the Royal Hobart Hospital, Tasmania, Australia, were retrospectively reviewed. The pre- and post-DOAC era cohorts included admissions from January 2011 to July 2013 and August 2013 to July 2015, respectively. Overall, 2,118 patients met our inclusion criteria. The overall rate of anticoagulation increased from 52.5% in the pre-DOAC era to 60.7% in the post-DOAC era (p <0.001). Moreover, prescribing of OACs among high-risk patients improved significantly (63.1% vs 55.2%, p = 0.001). OAC overprescribing in low-risk patients did not change significantly between the 2 cohorts (35.0% vs 42.9% in the pre- and post-DOAC eras, respectively, p = 0.59). In multivariate analysis, DOAC era (odds ratio [OR] 1.40, 95% confidence interval [CI] 1.17 to 1.68 and CHA2DS2-VASc ≥2 (OR 1.95, 95% CI 1.36 to 2.80) were independent predictors of OAC prescribing in both eras and the whole study period. Conversely, aging and previous bleeding were inversely associated with OAC prescribing. In conclusion, there has been a significant increase in OAC prescribing in the post-DOAC era, potentially driven by the widespread availability of DOACs. However, OAC underuse in high-risk patients and overuse in low-risk patients was apparent throughout our study. These findings highlight the need to identify the drivers of anticoagulant underuse and overuse and address them accordingly.

Bleeding-related admissions in patients with atrial fibrillation receiving antithrombotic therapy: results from the Tasmanian Atrial Fibrillation (TAF) study. Eur J Clin Pharmacol 2017; 73:1681-1689. [PMID: 28939954 DOI: 10.1007/s00228-017-2337-9] [Citation(s) in RCA: 2] [Impact Index Per Article: 0.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/13/2017] [Accepted: 09/15/2017] [Indexed: 12/19/2022]
Abstract
PURPOSE Limited data are available from the Australian setting regarding bleeding in patients with atrial fibrillation (AF) receiving antithrombotic therapy. We aimed to investigate the incidence of hospital admissions due to bleeding and factors associated with bleeding in patients with AF who received antithrombotic therapy. METHODS A retrospective cohort study was conducted involving all patients with AF admitted to the Royal Hobart Hospital, Tasmania, Australia, between January 2011 and July 2015. Bleeding rates were calculated per 100 patient-years (PY) of follow-up, and multivariable modelling was used to identify predictors of bleeding. RESULTS Of 2202 patients receiving antithrombotic therapy, 113 presented to the hospital with a major or minor bleeding event. These patients were older, had higher stroke and bleeding risk scores and were more often treated with warfarin and multiple antithrombotic therapies than patients who did not experience bleeding. The combined incidence of major and minor bleeding was significantly higher in warfarin- versus direct-acting oral anticoagulants (DOAC)- and antiplatelet-treated patients (4.1 vs 3.0 vs 1.2 per 100 PY, respectively; p = 0.002). Similarly, the rate of major bleeding was higher in patients who received warfarin than in the DOAC and antiplatelet cohorts (2.4 vs 0.4 vs 0.6 per 100 PY, respectively; p = 0.001). In multivariate analysis, increasing age, prior bleeding, warfarin and multiple antithrombotic therapies were independently associated with bleeding. CONCLUSION The overall rate of bleeding in this cohort was low relative to similar observational studies. The rate of major bleeding was higher in patients prescribed warfarin compared to DOACs, with a similar rate of major bleeding for DOACs and antiplatelet agents. Our findings suggest potential to strategies to reduce bleeding include using DOACs in preference to warfarin, and avoiding multiple antithrombotic therapies in patients with AF.

Abstract
BACKGROUND Patients' knowledge regarding their oral anticoagulant (OAC) treatment for stroke prevention in atrial fibrillation (AF), their level of medication adherence, and health literacy are known to affect treatment outcomes. However, contemporary data regarding the relationships between these variables are lacking. OBJECTIVE To investigate the relationships between anticoagulant knowledge, health literacy, and self-reported adherence in patients taking warfarin and the directly acting oral anticoagulants. METHODS A cross-sectional survey was conducted in 48 patients with AF identified from general practices. The Anticoagulation Knowledge Tool (AKT) was used to assess anticoagulation knowledge; the Short Test of Functional Health Literacy in Adults (s-TOFHLA) for health literacy; and the 8-item Morisky Medication Adherence Scale (MMAS) for medication adherence. RESULTS Participants had mean scores of 61.6 ± 15.8, 7.2 ± 1.1, and 24.7 ± 9.5 for the AKT, MMAS-8 and s-TOFHLA, respectively. Significant correlations were observed between anticoagulation knowledge and health literacy with medication adherence (0.37, P < .01 and .30, P < .05, respectively). Participants with inadequate health literacy had a significantly lower mean knowledge score than those with adequate health literacy (55.8 ± 15.9 vs 66.1 ± 14.4, P < .05). Participants who self-reported adherence to their OAC had significantly higher knowledge scores than those who did not (67.5 ± 13.3 vs 56.1 ± 16.2, P < .05). CONCLUSION Significant correlations between health literacy, OAC knowledge, and adherence were observed, and these relationships should to be considered by health professionals responsible for monitoring patients who are prescribed anticoagulants. We also observed serious gaps in OAC knowledge. Interventions designed to optimize the outcomes of anticoagulant treatment need to address these factors.

Abstract
As medication experts, pharmacists are key members of the patient’s healthcare team. Pharmacists must maintain their competence to practice to remain responsive to the increasingly complex healthcare sector. This paper seeks to determine how competence training for pharmacists may enhance quality in their professional development. Results of two separately administered surveys (2012 and 2013) were compared to examine the reported continued professional development (CPD) practices of Australian pharmacists. Examination of results from both studies enabled a focus on how the competency standards inform CPD practice. In the survey administered in 2012, 91% (n = 253/278) pharmacists reported that they knew their current registration requirements. However, in the survey administered in 2013, only 43% (n = 46/107) reported utilization of the National Competency Standards Framework for Pharmacists in Australia (NCS) to self-asses their practice as part of their annual re-registration requirements. Fewer, 23% (n = 25/107), used the NCS to plan their CPD. This may be symptomatic of poor familiarity with the NCS, uncertainty around undertaking self-directed learning as part of a structured learning plan and/or misunderstandings around what CPD should include. This is supported by thematic analysis of pharmacists’ social media comments. Initial and ongoing competence training to support meaningful CPD requires urgent attention in Australia. The competence (knowledge, skills and attributes) required to engage in meaningful CPD practice should be introduced and developed prior to entry into practice; other countries may find they are in a similar position.

Abstract
BACKGROUND Adverse drug reactions (ADRs) are the major cause of medication-related hospital admissions in older patients living in the community. This study aimed to develop and validate a score to predict ADR-related hospitalization in people aged ≥65 years. METHODS ADR-related hospitalization and its risk factors were determined using a prospective, cross-sectional study in patients aged ≥65 years admitted to two hospitals. A predictive model was developed in the derivation cohort (n = 768) and the model was applied in the validation cohort (n = 240). ADR-related hospital admission was determined through expert consensus from comprehensive reviews of medical records and patient interviews. The causality and preventability of the ADR were assessed based on the Naranjo algorithm and modified Schumock and Thornton criteria, respectively. RESULTS In the derivation sample (mean [±SD] age, 80.1±7.7 years), 115 (15%) patients were admitted due to a definite or probable ADR; 92.2% of these admissions were deemed preventable. The number of antihypertensives was the strongest predictor of an ADR followed by presence of dementia, renal failure, drug changes in the preceding 3 months and use of anticholinergic medications; these variables were used to derive the ADR prediction score. The predictive ability of the score, assessed from calculation of the area under the receiver operator characteristic (ROC) curve, was 0.70 (95% confidence interval (CI) 0.65-0.75). In the validation sample (mean [±SD] age, 79.6±7.6 years), 30 (12.5%) patients' admissions were related to definite or probable ADRs; 80% of these admissions were deemed preventable. The area under the ROC curve in this sample was 0.67 (95% CI 0.56-0.78). CONCLUSIONS This study proposes a practical and simple tool to identify elderly patients who are at an increased risk of preventable ADR-related hospital admission. Further refinement and testing of this tool is necessary to implement the score in clinical practice.

Abstract
Atrial fibrillation (AF) is a growing public health concern and remains an independent risk factor for ischemic stroke. Warfarin, a commonly used oral anticoagulant, is associated with a 60-70 % relative reduction in stroke risk and a reduction in mortality of 26 %. However, warfarin has several limitations, including a narrow therapeutic window, variable dose response, multiple interactions with other drugs and concurrent illnesses, and the need for frequent laboratory monitoring. In recent years, the direct acting oral anticoagulants (DOACs), including dabigatran, rivaroxaban, apixaban and edoxaban, have been developed to overcome the limitations of warfarin therapy. These treatment strategies are either comparable or superior to warfarin in stroke prevention in AF. Despite the documented effectiveness of oral anticoagulants in AF, patients may not derive optimal benefit if they fail to adhere or fail to continue with their medication. This may lead to treatment failure, increased hospitalization and mortality. This review summarizes the literature regarding adherence and persistence (or discontinuation) rates with oral anticoagulants in the management of AF; the impact of non-adherence and non-persistence on treatment outcomes; and the effectiveness of strategies to improve adherence and persistence with oral anticoagulant therapy.

Abstract
BACKGROUND Assessing and improving patients' anticoagulation knowledge can lead to better treatment outcomes. While validated knowledge instruments exist for use in people taking warfarin, these tools are not necessarily applicable to patients taking direct-acting oral anticoagulants. OBJECTIVE To develop and validate an oral anticoagulation knowledge instrument that is applicable to all oral anticoagulant medications. METHODS Ten anticoagulation experts participated in the development of the Anticoagulation Knowledge Tool to ensure content validity. The knowledge instrument was administered to three groups of participants comprising of 44 pharmacists, 50 patients and 50 members of the general public. A subgroup of participants in the patient and pharmacist group were retested approximately 2-3 months after the initial testing. Statistical tests were conducted to determine the validity and reliability of the scale, and item analysis was used to determine the performance of individual questions. RESULTS The 28-item instrument developed had a scale content validity index of 0.92, supporting content validity. The pharmacist group's mean score was significantly higher than that of the patient group, and the patient group scored significantly higher than the general public group (94% vs 62% vs 20%, respectively; p<0.001), supporting construct validity. Internal consistency reliability was acceptable with a Cronbach's α value of > 0.7 across the three groups, and the test-retest reliability was confirmed with a Pearson's correlation coefficient of 0.72 and 0.78 for the pharmacist and patient groups, respectively. CONCLUSION The Anticoagulation Knowledge Tool is a valid and reliable instrument that can be used in routine clinical practice to assess patients' anticoagulation knowledge.

Abstract
BACKGROUND AND OBJECTIVES Atrial fibrillation (AF) and the associated risk of stroke are emerging epidemics throughout the world. Suboptimal use of oral anticoagulants for stroke prevention has been widely reported from observational studies. In recent years, direct oral anticoagulants (DOACs) have been introduced for thromboprophylaxis. We conducted a systematic literature review to evaluate current practices of anticoagulation in AF, pharmacologic features and adoption patterns of DOACs, their impacts on proportion of eligible patients with AF who receive oral anticoagulants, persisting challenges and future prospects for optimal anticoagulation. LITERATURE SOURCE AND SELECTION CRITERIA In conducting this review, we considered the results of relevant prospective and retrospective observational studies from real-world practice settings. PubMed (MEDLINE), Scopus (RIS), Google Scholar, EMBASE and Web of Science were used to source relevant literature. There were no date limitations, while language was limited to English. Selection was limited to articles from peer reviewed journals and related to our topic. RESULTS Most studies identified in this review indicated suboptimal use of anticoagulants is a persisting challenge despite the availability of DOACs. Underuse of oral anticoagulants is apparent particularly in patients with a high risk of stroke. DOAC adoption trends are quite variable, with slow integration into clinical practice reported in most countries; there has been limited impact to date on prescribing practice. CONCLUSION Available data from clinical practice suggest that suboptimal oral anticoagulant use in patients with AF and poor compliance with guidelines still remain commonplace despite transition to a new era of anticoagulation featuring DOACs.

Abstract
Adverse drug reactions (ADRs) represent a major burden on society, resulting in significant morbidity, mortality, and health care costs. Older patients living in the community are particularly susceptible to ADRs, and are at an increased risk of ADR-related hospitalization. This review summarizes the available evidence on ADR-related hospital admission in older patients living in the community, with a particular focus on risk factors for ADRs leading to hospital admission and the need for a prediction tool for risk of ADR-related hospitalization in these individuals. The reported proportion of hospital admissions due to ADRs has ranged from 6% to 12% of all admissions in older patients. The main risk factors or predictors for ADR-related admissions were advanced age, polypharmacy, comorbidity, and potentially inappropriate medications. There is a clear need to design intervention strategies to prevent ADR-related hospitalization in older patients. To ensure the cost-effectiveness of such strategies, it would be necessary to target them to those older individuals who are at highest risk of ADR-related hospitalization. Currently, there are no validated tools to assess the risk of ADRs in primary care. There is a clear need to investigate the utility of tools to identify high-risk patients to target appropriate interventions toward prevention of ADR-related hospital admissions.

Abstract
OBJECTIVES To determine the extent of use and perceived relevance of the National Competency Standards Framework for Pharmacists in Australia (NCS). Based on these findings, to suggest approaches for the enhancement of pharmacy education for the profession locally and globally. METHODS Convenience sampling techniques were employed between November 2013 and June 2014 in conducting an online survey with Australian pharmacy students, interns, pharmacists and educators. KEY FINDINGS Data from 527 participants were included in the final analysis. Fewer students (52%, 96/183) and interns 78% (69/88) knew the NCS framing pharmacy practice compared with pharmacists (86%, 115/134). Despite knowledge that the NCS existed most participants reported poor familiarity with and use of the NCS. Registered pharmacists reported annual use but not for Continuing Professional Development (CPD) plans or annual re-registration requirements. Respondents reported that practical use of NCS (e.g. mentoring interns) increased their use for personal needs. Some participants suggested regular instruction on self-assessment skills development would enhance meaningful use of the NCS. CONCLUSION Despite self-assessment against NCS being mandated annually, Australia's practising pharmacists provided explanations for why this is not common in practice. The barriers provided by respondents are interconnected; their enablers are practical solutions to each barrier. The findings reinforce the notion that student pharmacists must have their competency standards, life-long learning and self-assessment skills embedded into their university curriculum to ensure a strong foundation for practice. The opportunity offered by periodic renewal of standards must prompt regular profession-wide evaluation of its education to practice nexus. Insights and author recommendations are portable to the pharmacy profession globally.

Abstract
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.

Abstract
The often cited need to achieve ≥95% (nearly perfect) adherence to antiretroviral therapy (ART) for successful virologic outcomes in HIV may present a barrier to initiation of therapy in the early stages of HIV. This meta-analysis synthesized 43 studies (27,905 participants) performed across >26 countries, to determine the relationship between cut-off point for optimal adherence to ART and virologic outcomes. Meta-analysis was performed using a random-effect model to calculate pooled odds ratios with corresponding 95% confidence intervals. The mean rate of patients reporting optimal adherence was 63.4%. Compared with suboptimal adherence, optimal adherence was associated with a lower risk of virologic failure (0.34; 95% CI: 0.26-0.44). There were no significant differences in the pooled odds ratios among different optimal adherence thresholds (≥98-100%, ≥95%, ≥80-90%). Study design (randomized controlled trial vs observational study) (regression coefficient 0.74, 95% CI: 0.04-1.43, P < 0.05) and study region (developing vs developed countries; regression coefficient 0.56, 95% CI: 0.01-1.12, P < 0.05) remained as independent predictors of between-study heterogeneity, with more patients with optimal adherence from developing countries or randomized controlled trials experiencing virologic failure. The threshold for optimal adherence to achieve better virologic outcomes appears to be wider than the commonly used cut-off point (≥95% adherence). The cut-off point for optimal adherence could be redefined to a slightly lower level to encourage the prescribing ART at an early stage of HIV infection.

Abstract
Developing appropriate strategies to sustain optimal medication adherence among the increasing number of HIV-positive patients taking antiretroviral therapy (ART) in sub-Saharan Africa is a major challenge. The objective of this study was to determine patient, regimen, disease, patient-provider, and healthcare-related factors associated with adherence with ART over a one-year period, and assess the impact of adherence on treatment outcomes. We performed a prospective, observational study among 246 patients who were initiated on ART in Ethiopia. Of 172 who completed follow-up, 130 (75.6%) had ≥95% adherence. In the multivariate analyses, a higher baseline BMI (OR, 1.2; 95% CI 1.0, 1.4) and use of reminder devices (OR, 9.1; 95% CI 2.0, 41.6) remained positively associated with adherence, while a higher HIV symptom and adverse drug reaction distress score was an independent negative predictor of adherence (OR, 0.90; 95% CI 0.9, 1.0) CD4 count increase was significantly higher in the adherent patients compared to non-adherent patients at 12 months (159 cells/µL [interquartile range (IQR), 72-324 cells/µL] vs. 132 cells/µL [IQR, 43-190 cells/µL]; p = 0.026). Our findings indicate that interventions aimed at improving adherence and thereby treatment outcomes in patients initiated on ART should promote the use of reminder devices, and monitor HIV symptoms and adverse reaction distress and nutritional status.
