Evidence-based Medication knowledge Brokers in Residential Aged CarE (EMBRACE): protocol for a helix-counterbalanced randomised controlled trial.

INTRODUCTION: Clinical practice guidelines recommend against the routine use of psychotropic medications in residential aged care facilities (RACFs). Knowledge brokers are individuals or groups who facilitate the transfer of knowledge into practice. The objective of this trial is to evaluate the effectiveness and cost-effectiveness of using knowledge brokers to translate Australia's new Clinical Practice Guidelines for the Appropriate Use of Psychotropic Medications in People Living with Dementia and in Residential Aged Care. METHODS AND ANALYSIS: The Evidence-based Medication knowledge Brokers in Residential Aged CarE (EMBRACE) trial is a helix-counterbalanced randomised controlled trial. The 12-month trial will be conducted in up to 19 RACFs operated by four Australian aged care provider organisations in Victoria, New South Wales, Western Australia and Queensland. RACFs will be randomised to receive three levels of implementation strategies (knowledge broker service, pharmacist-led quality use of medications education activities and distribution of the Guidelines and supporting materials) across three medication contexts (antipsychotics, benzodiazepines and antidepressants). Implementation strategies will be delivered by an embedded on-site aged care pharmacist working at a system level across each participating RACF. All RACFs will receive all implementation strategies simultaneously but for different medication contexts. The primary outcome will be a composite dichotomous measure of 6-month RACF-level concordance with Guideline recommendations and good practice statements among people using antipsychotics, benzodiazepines and antidepressants for changed behaviours. Secondary outcomes will include proportion of residents with Guideline concordant use of antipsychotics, benzodiazepines and antidepressants measured at the RACF-level and proportion of residents with psychotropic medication use, hospitalisation, falls, falls with injury, polypharmacy, quality of life, activities of daily living, medication incidents and behavioural incidents measured at the RACF-level. DISCUSSION: The EMBRACE trial investigates a novel guideline implementation strategy to improve the safe and effective use of psychotropic medications in RACFs. We anticipate that the findings will provide new information on the potential role of knowledge brokers for successful and cost-effective guideline implementation.

A scoping review of health system guidelines for pharmacist responsibilities when dispensing opioids.

Introduction: Prescription opioid use and evidence of the harm caused by these medicines has increased over the past 20-30 years. Despite a number of system level interventions, the opioid crisis has not yet resolved in Australia or globally. Pharmacists are increasingly required to take a proactive, clinical role to fulfil their responsibility for patient outcomes relating to both medication efficacy and safety. Aim: To evaluate the current health system guidelines available to pharmacists dispensing opioids and to examine the implications of this guidance on pharmacist responsibility. Methods: A scoping review was conducted by searching in CINAHL, MEDLINE, Embase, PubMed and Web of Science, in addition to the grey literature and referral from topic experts to collate a list of current health system guidelines relevant to pharmacists dispensing opioids. These guidelines were then examined through thematic analysis and the use of the "Appraisal of Guidelines Research & Evaluation-Health Systems" tool (AGREE-HS). Results: Ten health system guidelines were identified in the search. Identified guidelines were published in Australia, the United States, and the United Kingdom. Health system guidelines analysed in this study most commonly provide general practice statements that are not specific to opioid medicines. Current guidelines frequently recommend risk assessment, but less commonly provide implementable risk mitigation advice. Additionally, guidelines are of poor overall quality when analysed through metrics relating to their development and implementation. Conclusion: There are gaps in current health system guidelines which contribute to perceived barriers in pharmacy practice. Current health system guidance does not provide a clear account of the responsibilities of pharmacists when dispensing opioids. This study provides an argument for the development of implementable health system guidelines that support pharmacists in taking direct responsibility for patient outcomes when dispensing opioid medicines.

Embedded on-site aged care pharmacists in Australia: Insights from early adopters of a new workforce model.

OBJECTIVE: To explore the roles of early adopters of Australia's embedded on-site pharmacist model in supporting quality use of medications in residential aged care facilities (RACFs). METHODS: Qualitative semistructured interviews were conducted with 15 pharmacists working as embedded on-site pharmacists, or beyond the scope of traditional consultant pharmacist roles in Australian RACFs. Interviews were audio-recorded, transcribed and thematically analysed independently by two investigators using an inductive approach. Deductive analysis was also undertaken using a knowledge broker framework: knowledge manager, linkage agent and capacity builder. RESULTS: Dominant themes were roles and benefits of embedded pharmacists, factors associated with success and challenges. Roles and benefits included (1) resident-level interventions and an enhanced ability to provide collaborative outcome-focussed resident-centred care, including timely input and follow-up, and improved relationships with residents, family and interdisciplinary team; and (2) system-level interventions such as contributing to clinical governance and quality improvement. Factors associated with success included personal capabilities and approach of the pharmacist, and organisational culture and sector-wide support. Challenges included pharmacist workforce shortages, perceived lack of pharmacist readiness and difficulty determining an appropriate service model. Deductive coding demonstrated roles of embedded pharmacists were consistent with all three activities of a knowledge broker. CONCLUSIONS: This study highlights the resident- and system-level roles and benefits of embedded on-site pharmacists, and provides a framework for defining this emerging workforce model in Australian RACFs.

Health literacy in Pakistani migrants in Australia-An emerging and neglected culturally and linguistically diverse community.

ISSUE ADDRESSED: Pakistani migrants are one of the fastest-growing culturally and linguistically diverse (CALD) communities in Australia, but there is currently a lack of information regarding their health literacy. This study aimed to investigate the health literacy of Pakistani migrants residing in Australia. METHODS: Using a cross-sectional study design, health literacy was measured using the Urdu version of Health Literacy Questionnaire (HLQ). Descriptive statistics and linear regression were used to describe the health literacy profile of respondents and to examine its association with their demographic characteristics. RESULTS: The responses of 202 Pakistani migrants were included. The median age of the respondents was 36 years, 61.8% were males and 87.6% had a university education. The majority spoke Urdu at home and almost 80% were Australian permanent residents or citizens. Pakistani respondents scored high on HLQ domains; feeling understood by health providers (Scale 1), social support for health care (Scales 4), engaging with health care providers (Scale 6) and understanding health information (Scale 9). The respondents scored low on HLQ domains; having sufficient information (Scale 2), actively managing health (Scale 3), appraisal of health information (Scale 5), navigating the health care system (Scale 7) and ability to find information (Scale 8). In the regression model, university education and age were significantly associated with health literacy in almost all the domains, but the effect size was small for age. Speaking English at home and being a permanent resident were also associated with better health literacy in two to three HLQ domains. CONCLUSIONS: Health literacy strengths and weaknesses of Pakistani migrants residing in Australia were identified. Health care providers and organisations may use these findings to tailor health information and services to better support health literacy in this community. SO WHAT?: This study will inform future interventions to better support health literacy and reduce health disparities in Pakistani migrants residing in Australia.

Experiences and learnings of pharmacists, students, and clinical assistants working collaboratively in a COVID-19 vaccination clinic: a qualitative study.

Background: The involvement of pharmacists and pharmacy clinical assistants (CAs) in hospital clinics has demonstrated benefits for improving medication safety and care delivery. Internationally, pharmacy staff played a crucial role in the safe storage, provision and administration of vaccines, as well as reinforcement of pharmacovigilance efforts during the COVID-19 pandemic. In Australia, healthcare providers collaborated to rapidly facilitate a phased COVID-19 vaccination program. The perspectives of the pharmacy team, including pharmacy students, involved in implementing novel health services are underexplored in the literature. Objective: To describe the key learnings in how a team of pharmacists, CAs and pharmacy students contributed to the COVID-19 vaccine service, and to explore their preparedness and experiences working at a vaccination clinic within a quaternary hospital. Method: This study involved semi-structured interviews with pharmacy students, CAs and pharmacists. All pharmacy staff who worked in the clinic were invited to participate in the study and a snowball strategy was used to maximise recruitment. The interviews were audio-recorded, transcribed, and analysed using inductive thematic techniques to identify major themes. Results: A total of 11 participants were interviewed including: four pharmacists, four CAs and three undergraduate students. Using thematic analysis, five main themes were identified: (1) Potential for student value and experiential learning; (2) Adaptive procedures and work practices in a rapidly changing environment; (3) Clear leadership, with role clarity, role expansion and interchangeability; (4) Supportive learning environment and (5) Stakeholder drivers for service delivery and to optimise societal benefit. These five themes often interacted with each other, highlighting the complexities of implementing and operating the service. Conclusions: The vaccine clinic service provided a novel and valuable opportunity for students, CAs, and pharmacists to work collaboratively, extending their scope of practice to contribute to better national health outcomes. Participants expressed their support for future initiatives involving pharmacy students and healthcare staff collaborating in hospital settings.

Roles and effectiveness of knowledge brokers for translating clinical practice guidelines in health-related settings: a systematic review.

BACKGROUND: Poor translation of clinical practice guidelines (CPGs) into clinical practice is a barrier to the provision of consistent and high-quality evidence-based care. The objective was to systematically review the roles and effectiveness of knowledge brokers (KBs) for translating CPGs in health-related settings. METHODS: MEDLINE, Embase, PsycINFO and CINAHL Plus were searched from 2014 to June 2022. Randomised controlled trials (RCTs), controlled and uncontrolled preintervention and postintervention studies involving KBs, either alone or as part of a multicomponent intervention, that reported quantitative postintervention changes in guideline implementation in a healthcare setting were included. A KB was defined as an intermediary who facilitated knowledge translation by acting in at least two of the following core roles: knowledge manager, linkage agent or capacity builder. Specific activities undertaken by KBs were deductively coded to the three core roles, then common activities were inductively grouped. Screening, data extraction, quality assessment and coding were performed independently by two authors. RESULTS: 16 studies comprising 6 RCTs, 8 uncontrolled precomparisons-postcomparisons, 1 controlled precomparison-postcomparison and 1 interrupted time series were included. 14 studies (88%) were conducted in hospital settings. Knowledge manager roles included creating and distributing guideline material. Linkage agent roles involved engaging with internal and external stakeholders. Capacity builder roles involved audit and feedback and educating staff. KBs improved guideline adherence in 10 studies (63%), had mixed impact in 2 studies (13%) and no impact in 4 studies (25%). Half of the RCTs showed KBs had no impact on guideline adherence. KBs acted as knowledge managers in 15 (94%) studies, linkage agents in 11 (69%) studies and capacity builders in all studies. CONCLUSION: Knowledge manager and capacity builder roles were more frequently studied than linkage agent roles. KBs had mixed impact on translating CPGs into practice. Further RCTs, including those in non-hospital settings, are required. PROSPERO REGISTRATION NUMBER: CRD42022340365.

Mapping Australian pharmacy school curricula for content related to pharmacogenomics.

Background: Pharmacogenomics (PGx) is a rapidly growing field which promises to deliver personalized, more effective medications tailored to genetic information. Although the pharmacy profession is expected to lead the translation of pharmacogenomics into widespread clinical implementation, there is a reported lack of preparedness among its members. Assessing pharmacogenomic-related training in Australian pharmacy program curricula may highlight educational gaps and provide guidance for curricula revision. Objective: To examine pharmacogenomic content in Australian tertiary pharmacy program curricula. Methods: We reviewed the curriculum of 22 Australian registrable pharmacy degrees, including 16 Bachelors of Pharmacy programs (with or without honors) and six Masters of Pharmacy programs, for content related to pharmacogenomics and genetics. This was done by screening the publicly available electronic course profiles on each institution's website and searching for key terms such as "pharmacogenomics," "pharmacogenetics," "genes," and "genetics". Three mapping activities were completed to assess the breadth and depth of pharmacogenomic training according to; 1. Bloom's taxonomy, 2. Author-assigned domains comprising; Enabling science, Translational science and Clinical implementation, and 3. Pharmacogenomic competencies from the National Human Genome Research Institute (NHGRI). Results: A total of 18 (82%) pharmacy registrable degree programs incorporated pharmacogenomics and/or genetics in their curricula. Four programs (18%) offered standalone PGx courses and 10 (45%) contained integrated PGx content in other science-related courses (i.e. pharmaceutical biology, biochemistry, microbiology etc.). Mapping activities showed that most learning objectives related to the "Understand" level of Bloom's taxonomy (61%), the "Basic Genetic Concepts" domain of NHGRI's competencies (64%) and "Enabling science" (84%). Conclusions: Most Australian pharmacy registrable degrees have incorporated pharmacogenomic content in their curricula however, the scope of training is limited. Revisions to course curricula should be made to incorporate additional education with a focus on application-based training of clinical pharmacogenomics.

Investigating the impact of patient-centred labels on comprehension of medication dosing: a randomised controlled trial.

OBJECTIVE: This study aims to implement a version of patient-centred labels (PCL) consistent with current labelling practice in Australia; assess the effectiveness of PCL in relation to the proportion of participants that correctly comprehend dosing instructions, and explore the proportion of correct comprehension of PCL in participants with both low and high health literacy. DESIGN: Randomised controlled trial. SETTING: A large tertiary care hospital in Brisbane, Queensland, Australia. PARTICIPANTS: 121 participants with a majority born in Australia (65.3%), New Zealand (14.0%), the UK (6.6%) and Ireland (2.5%). INTERVENTION: Participants were randomly assigned to either a panel of three PCL (n=61) or three standard labels (n=60) and asked to comprehend their assigned panel of labels. OUTCOME MEASURES: Difference in the proportion of participants that correctly comprehend dosing instructions provided on PCL compared with standard labels. The two-proportion test was used to measure the impact of PCL on the proportion of participants correctly comprehending dosing instructions. RESULTS: A greater proportion of participants were able to accurately comprehend PCL compared with standard labels. The proportion of participants who were able to correctly comprehend dose instructions provided on all three labels was significantly higher in the group that received PCL; 23.3% standard vs 83.6% PCL, p<0.001. The effect was observed in both low and high health literacy participants. The proportion of participants with accurate label comprehension was higher in participants with low Newest Vital Signs scores (8.3% standard vs 85.7% PCL, p<0.001) and low Rapid Estimate of Adult Literacy in Medicine scores (10.5% standard vs 96.0% PCL, p<0.001) who received PCL. CONCLUSION: This study supports the use of PCL in Australian pharmacy practice. PCL provide simple, clear and explicit dosing instructions to patients. Implementing PCL may reduce the risk of misinterpreting dosing instructions by patients and improve quality use of medicines. TRIAL REGISTRATION NUMBER: ACTRN12621000083897; Results.

New Insights on Tramadol and Immunomodulation.

PURPOSE OF REVIEW: Opioids are administered to cancer patients although concerns have been raised that they may promote tumour growth or metastasis owing to their ability to suppress anti-cancer immunity. Tramadol has been reported to preserve or promote the immune response and may therefore be preferred to other opioids in cancer patients. We reviewed the literature documenting the immunomodulatory effects of tramadol. RECENT FINDINGS: Recent clinical evidence appears to confirm that tramadol possesses anti-inflammatory properties, and preserves some signalling cascades of the immune system relevant to anti-cancer defence. Tramadol is reported to promote or preserve immunity including natural killer cell activity which is important in anti-cancer defences.

Improving pharmacy practice in relation to complementary medicines: a qualitative study evaluating the acceptability and feasibility of a new ethical framework in Australia.

BACKGROUND: There is a need for clearer guidance for pharmacists regarding their responsibilities when selling complementary medicines. A recently published ethical framework provides guidance regarding the specific responsibilities that pharmacists need to meet in order to fulfil their professional obligations and make a positive contribution to health outcomes when selling complementary medicines. OBJECTIVE: Evaluate the acceptability and feasibility of a new ethical framework for the sale of complementary medicines in community pharmacy. METHODS: Australian community pharmacists were invited to participate in online focus groups and interviews. Participants were recruited via multiple methods, including social media and the professional networks of pharmacy groups. Participants were provided the ethical framework prior to the discussion. Discussions were transcribed verbatim and analysed using thematic analysis. RESULTS: Seventeen community pharmacists participated in the study (11 in 4 focus groups and 6 in individual interviews). There was good representation among participants in terms of gender, years of practice, pharmacy location and script volume. Participants differed in how proactive they were in relation to selling and providing advice on complementary medicines, how they interpreted evidence in relation to complementary medicines, and how they navigated their practice within the retail environment of community pharmacy. The majority of participants found the framework was acceptable for practice and was feasible for implementation with targeted support. Participants identified two important areas for targeted support in implementing the framework: improved access to evidence-based information resources on complementary medicines and independent evidence-based education and training on complementary medicine for pharmacists and pharmacy support staff. CONCLUSION: The ethical framework addresses an important gap in providing specific professional guidance to pharmacists when selling complementary medicines. The results of the study suggest that the framework may be acceptable to community pharmacists and be feasible to implement with targeted support.

Hospital pharmacists' ethical exposure and decision-making.

BACKGROUND: Studies have explored community pharmacy ethical dilemmas; however, limited research exists on hospital pharmacy ethical issues and pharmacists' ethical decision-making processes. Research exploring this is timely, considering developments in hospital pharmacy practices, new hospital pharmacist roles, and evolving responsibilities. AIM/OBJECTIVES: To explore hospital pharmacists' ethical decision-making and processes for managing ethical challenges in the context of evolving Australian hospital pharmacy practices. METHODS: Face-to-face semi-structured interviews with 20 purposively-selected hospital pharmacists from four Queensland Health hospitals. An interview guide with 11 open-ended questions and prompts was developed, validated, and trialed. Pharmacists who consented received the guide prior to interviews. Interviews were audio recorded, transcribed verbatim, and compared with field notes. Transcribed data were imported into NVivo 12 to facilitate coding and thematic analysis. RESULTS: Participants were interviewed January to April 2019; median interview duration was 17.45 min. Data saturation was reached. Participants' experiences ranged from junior level pharmacists to senior management positions, in clinical and non-clinical roles. Emerging themes were: 1) influences on the development of ethical decision-making skills, 2) ethical decision-making is an integral part of the hospital pharmacist's role, and 3) institutional requirements and settings impact on ethical exposure. A wide range of contemporary ethical issues unique to hospital pharmacy practice, mostly involving complex medication management safety, supply, and cost scenarios, were identified. Junior pharmacists indicated they would benefit from additional training, mentorship, and availability of hospital-specific targeted ethics resources. CONCLUSION: The findings highlighted that hospital pharmacists are regularly faced with ethical issues unique to the hospital pharmacy practice context. Application of sound and structured ethical reasoning and decision-making is, therefore, required in this setting. Participants identified many interrelated factors that impacted their ethical reasoning and behaviour. This study identified gaps that, once addressed, will better support ethical reasoning in hospital pharmacy settings.

Translating and validating the Health Literacy Questionnaire into Urdu: a robust nine-dimension confirmatory factor model.

Pakistani migrants are one of the fastest-growing communities in Australia, and the majority speak Urdu at home. There is a lack of information regarding the health literacy of this population. This study aimed to translate the Health Literacy Questionnaire (HLQ) into Urdu and to explore its psychometric properties. A structured standardized procedure was followed to translate and validate HLQ into Urdu. Data were collected from 202 Pakistani migrants residing in Australia. The HLQ-Urdu was well understood by the respondents. The structural properties of HLQ-Urdu were close to the original HLQ. Data for all HLQ scales met pre-specified criteria for fit in the one-factor CFA model. The composite reliability was high, ranging from 0.84 to 0.91. A strict nine-factor CFA model was also fitted to the data with no cross-loadings or correlated residuals allowed, which showed excellent model fit statistics [χ2WLSMV = 1266.022 (df = 866, p = 0.000), comparative fit index = 0.995, Tucker-Lewis index = 0.994, root mean square error of approximation = 0.050 and standardized root mean square residual = 0.069]. The Urdu version of HLQ showed robust psychometric properties. This HLQ-Urdu tool is now ready to be used to assess health literacy in Pakistani migrants in Australia. Availability of health literacy tools in migrant languages may help healthcare providers better understand the health literacy needs of migrant communities.

An ethical framework for the responsibilities of pharmacists when selling complementary medicines.

BACKGROUND: Whether pharmacists should sell complementary medicines that lack evidence of effectiveness is an important ethical question which is not explicitly addressed in the existing literature or professional guidelines. The question arises because many complementary medicines lack rigorous evidence that they are effective. There is a need for specific practical guidance for pharmacists regarding their responsibilities when selling complementary medicines. OBJECTIVE: Outline and defend an ethical framework for the responsibilities of pharmacists when selling complementary medicines. METHOD: Principle-based ethics consists in the application of the four bioethical principles to make decisions in healthcare. A public health argument is provided that supports the sale of complementary medicines in pharmacy providing pharmacists meet a number of specific professional responsibilities. The theoretical resources provided by principle-based ethics are used to develop and defend a framework for the responsibilities of pharmacists when selling complementary medicines. The proposed framework is defended against counter-arguments that propose a stricter or more lenient approach. RESULTS: The framework identifies the following responsibilities of pharmacists selling complementary medicines: (1) pharmacists should provide evidence-based recommendations to consumers regarding complementary medicines, (2) pharmacists should train all staff in a pharmacy to ensure that they provide evidence-based recommendations regarding complementary medicines and refer to a pharmacist when required, (3) when providing advice, pharmacists should provide sufficient information for consumers to make informed decisions, (4) pharmacists should setup the pharmacy so that consumers are offered advice from a pharmacist when purchasing complementary medicines; pharmacists need to be available to provide that advice, and (5) pharmacists must be vigilant for complementary medicine harm and intervene if risk of harm is significant. CONCLUSION: The framework provides practical guidance for pharmacists regarding their responsibilities when selling complementary medicines.

A clinical audit of oral anticoagulant therapy in aged care residents with atrial fibrillation.

Background Atrial fibrillation (AF) is a risk factor for stroke in older people. Oral anticoagulants can reduce stroke risk but they are commonly under prescribed in the elderly, often due to concerns regarding the risk of bleeding. Prescribing in aged care residents may also be further complicated by associated geriatric conditions such as dementia and risk of falls. Systematic assessment of stroke and bleed risk can help identify people with AF expected to benefit from anticoagulant therapy and optimise prescribing. Objective The aim of this study was to assess the prescribing of anticoagulants in elderly aged care residents in accordance with Australian guideline recommendations. Setting Nineteen aged care facilities across southeast Queensland. Method A clinical audit of anticoagulant therapy in aged care residents was conducted. Main outcome measure Information was collected from the records of residents with non-valvular AF to assess the risk of stroke and bleeding and compare this prescribing to current evidence-based guidelines for anticoagulation in AF. Results A total of 1754 residents were screened with 359 (20.4%) identified to have a diagnosis of non-valvular AF. There were 356 (99.2%) residents with non-valvular AF and a sufficiently high risk of stroke to warrant the use of an anticoagulant. Of these, 172 (48.3%) were prescribed an oral anticoagulant and 40 (11.2%) residents had a documented decision not to prescribe oral anticoagulants in their records. The majority of residents prescribed anticoagulation were receiving non-vitamin K antagonists (76.8%). The prescribed dose was consistent with recommendations for 44.8% of residents prescribed oral anticoagulant therapy. Conclusion Many residents with non-valvular AF and significant risk of stroke were not receiving oral anticoagulation despite a lack of documented reason for non-prescribing. Non-vitamin K antagonists were widely prescribed but dosing of these agents could still be improved. There remains a need to improve anticoagulant prescribing for aged care residents and optimise stroke prevention in this population.

We are all patient-centred now, aren't we? Lessons from new pharmacy graduates.

INTRODUCTION: Patient-centredness is considered integral to the delivery of modern healthcare. This qualitative, longitudinal study explored the meaning and development of the practice of pharmacy graduates, leading to a focus on patient-centredness. The approach adopted in this study aligned with the principles of hermeneutic phenomenology. METHODS: Twelve pharmacy graduates (seven females) from The University of Queensland were observed at work and interviewed about their experiences of pharmacy practice every six months for two years following graduation. RESULTS: These 12 graduates initially understood and enacted pharmacy practice in a range of ways. A distinguishing characteristic related to how patients/customers featured in their practice. For some, ensuring the efficient supply or administration of correct and safe medicines with instructions was the focus, with patients viewed as source and recipient of information. For others, the focus was communicating effectively with patients/customers to provide individualised advice to avoid medication-related problems. A third group focused on achieving a broader goal, to provide individualised care to optimise health outcomes from medicines. Initial understanding of patient-centredness remained largely unchanged for most participants over the two years, despite the passage of time and experience gained. CONCLUSIONS: This study calls into question an assumption of a common meaning for patient-centredness. The findings highlight the need to question and debate what patient-centredness means in contemporary pharmacy practice, rather than simply being an aspirational or theoretical concept. It is important that pharmacists and educators appreciate the centrality of understanding of practice for development, to optimally facilitate the development of patient-centred pharmacists.

Pharmacists' perceived responsibility for patient care when there is a risk of misadventure: a qualitative study.

OBJECTIVE: To investigate how community pharmacists view their responsibility for patient care in a scenario involving opioid use with significant risk of toxicity or misadventure. METHODS: A case scenario was developed based on an Australian coronial inquiry involving a patient suffering fatal toxicity following misuse of opioids. Community pharmacists working in Brisbane, Queensland, were invited to take part in face-to-face semi-structured interviews at their place of work. Participants were asked how they would respond to the scenario in practice and their perceived responsibilities. KEY FINDINGS: Twenty-one pharmacists were interviewed. Participants identified similar actions in response to the case, and potential barriers and enablers. Participants differed with regard to how they described their perceived scope of practice and degree of responsibility in response to the case. Most participants described their scope of practice in terms of medication management with a focus on patient outcomes. Some participants described a narrower scope of practice that focused on either medicine supply or legal aspects. Participants who described a medication management focus differed in their views regarding their responsibility for patient outcomes in the case. CONCLUSION: Pharmacists in this study varied in terms of their perceived scope of practice and responsibility to patient outcomes in response to a case involving a patient at risk of opioid-related harm. Further work on pharmacist responsibility may reduce this variability.

Better evaluating mechanisms in medicine. Book Review: Evaluating Evidence of Mechanisms in Medicine.

Evidence of mechanisms plays an important role in medical decision-making, but this role is less well articulated than that of clinical trial evidence. A new book, Evaluating Evidence of Mechanisms in Medicine: Principles and Procedures, provides a framework and resources for explicitly evaluating evidence of mechanisms when assessing claims of efficacy and external validity. This review outlines the overall approach of the book, the contribution it makes to evidence evaluation in medicine and makes some suggestions for further work that will aid implementation of the framework into clinical decision-making.

Better understanding the influence and complexity of beliefs on medication adherence in asthma.

OBJECTIVE: The aim was to better understand how beliefs influence medication adherence in asthma. METHODS: All participants were prescribed an inhaled corticosteroid for a diagnosis of asthma. Each participant completed a survey consisting of: Beliefs about Medicines Questionnaire (BMQ), Brief-Illness Perception Questionnaire (B-IPQ) and Multi-dimensional Health Locus of Control Scale (MHLCS). Adherence to inhaled corticosteroids was elicited using the Medication Adherence Report Scale (MARS). Multiple linear regression with interaction effects was used to identify significant predictors of medication adherence and interactions between beliefs. RESULTS: A total of 198 participants completed the survey. The mean(±SD) MARS score was 19.2(±4.5). A multivariable model (adjusted R2 = 0.39) predicted adherence using: age, asthma hospitalisation, timeline (B-IPQ) subscale, necessity and concern (BMQ) subscales, doctor (MHLCS) subscale and the two interaction effects (concerns [BMQ] moderated by chance [MHLCS] and treatment control [B-IPQ] moderated by understanding [B-IPQ]). CONCLUSION: The findings of this study contribute to a better understanding of the role of beliefs in medication adherence in asthma. Certain beliefs meaningfully interrelate and change the relationship they have with medication adherence. PRACTICE IMPLICATIONS: If these beliefs are causally related to medication adherence and can be intervened upon, the findings are useful for providing targets to personalise adherence support.

The use of mechanistic evidence in drug approval.

The role of mechanistic evidence tends to be under-appreciated in current evidence-based medicine (EBM), which focusses on clinical studies, tending to restrict attention to randomized controlled studies (RCTs) when they are available. The EBM+ programme seeks to redress this imbalance, by suggesting methods for evaluating mechanistic studies alongside clinical studies. Drug approval is a problematic case for the view that mechanistic evidence should be taken into account, because RCTs are almost always available. Nevertheless, we argue that mechanistic evidence is central to all the key tasks in the drug approval process: in drug discovery and development; assessing pharmaceutical quality; devising dosage regimens; assessing efficacy, harms, external validity, and cost-effectiveness; evaluating adherence; and extending product licences. We recommend that, when preparing for meetings in which any aspect of drug approval is to be discussed, mechanistic evidence should be systematically analysed and presented to the committee members alongside analyses of clinical studies.
