- Abstract
Objective: To investigate whether integrating pharmacists into general practices reduces the number of unplanned re-admissions of patients recently discharged from hospital. Design, setting: Stepped wedge, cluster randomised trial in 14 general practices in southeast Queensland. Participant(s): Adults discharged from one of seven study hospitals during the seven days preceding recruitment (22 May 2017 - 14 March 2018) and prescribed five or more long term medicines, or having a primary discharge diagnosis of congestive heart failure or exacerbation of chronic obstructive pulmonary disease. Intervention(s): Comprehensive face-to-face medicine management consultation with an integrated practice pharmacist within seven days of discharge, followed by a consultation with their general practitioner and further pharmacist consultations as needed. Major outcomes: Rates of unplanned, all-cause hospital re-admissions and emergency department (ED) presentations 12 months after hospital discharge; incremental net difference in overall costs. Result(s): By 12 months, there had been 282 re-admissions among 177 control patients (incidence rate [IR], 1.65 per person-year) and 136 among 129 intervention patients (IR, 1.09 per person-year; fully adjusted IR ratio [IRR], 0.79; 95% CI, 0.52-1.18). ED presentation incidence (fully adjusted IRR, 0.46; 95% CI, 0.22-0.94) and combined re-admission and ED presentation incidence (fully adjusted IRR, 0.69; 95% CI, 0.48-0.99) were significantly lower for intervention patients. The estimated incremental net cost benefit of the intervention was $5072 per patient, with a benefit-cost ratio of 31:1. Conclusion(s): A collaborative pharmacist-GP model of post-hospital discharge medicines management can reduce the incidence of hospital re-admissions and ED presentations, achieving substantial cost savings to the health system.

- Abstract
The goal of health professional education programs is to produce competent graduates, with an ability to work collaboratively as effective healthcare team members. We explored the reflections of students and clinical facilitators, in response to participation in a structured interprofessional education (IPE) clinical placement program. In our qualitative study we used an exploratory case study design. In our analysis, we highlight the benefits of interprofessional practice. Key themes identified by students included: limited opportunities to engage in IPE across their course; lack of clarity around IPE; value of IPE for students, practitioners, and patient outcomes; and need for IPE opportunities to be integrated into placements. Key themes identified by the clinical facilitators included: being reminded of the value of IPE for students and patients; preparation for IPE placements need to be embedded in curricula; coordination and communication of IPE learning activities need to be clear for staff and students; and IPE should continue as part of the broader clinical education agenda. Our findings reinforce the notion that students and clinical facilitators value the importance of IPE for student learning within the clinical placement setting. The outcomes offer valuable insights for universities and hospital and health care contexts for setting up and implementing IPE activities, and we provide recommendations for improving ongoing IPE efforts within clinical placement setting.

- Abstract
Introduction: A model of general practitioner (GP) and pharmacist collaboration in primary care may be an effective strategy to reduce medication-related problems and provide better support to patients after discharge. The aim of this study is to investigate whether a model of structured pharmacist and GP care reduces hospital readmissions in high-risk patients. Methods and analysis: This protocol details a stepped-wedge, cluster-randomised trial that will recruit participants over 9 months with a 12-month follow-up. There will be 14 clusters each representing a different general practice medical centre. A total of 2240 participants will be recruited from hospital who attend an enrolled medical centre, take five or more long-term medicines or whose reason for admission was related to heart failure or chronic obstructive pulmonary disease. The intervention is a multifaceted service, involving a pharmacist integrated into a medical centre to assist patients after hospitalisation. Participants will meet with the practice pharmacist and their GP after discharge to review and reconcile their medicines and discuss changes made in hospital. The pharmacist will follow-up with the participant and liaise with other health professionals involved in the participant's care. The control will be usual care, which usually involves a patient self-organising a visit to their GP after hospital discharge. The primary outcome is the rate of unplanned, all-cause hospital readmissions over 12 months, which will be analysed using a mixed effects Poisson regression model with a random effect for cluster and a fixed effect to account for any temporal trend. A cost analysis will be undertaken to compare the healthcare costs associated with the intervention to those of usual care. Ethics and dissemination: The study has received ethical approval (HREC/16/QRBW/410). The study findings will be disseminated through peer-reviewed publications, conferences and reports to key stakeholders.Copyright

What is known and objective The STOPP/START tool has been validated to assess elderly patients for potentially inappropriate prescribing. This study aimed to assess the effect of inclusion of a pharmacist on a physician-led ward round on potentially inappropriate prescribing in hospitalized elderly patients. Methods This was an observational study of prescribing for patients using the STOPP/START tool at three points during hospital stay; admission to hospital, on transfer to the specialized geriatric unit and on discharge from hospital. Data were collected over 4 months pre- and post-introduction of a pharmacist to a physician-led ward round. Demographic and clinical data, including total number of medications and STOPP/START criteria met, were collected. The mean number of STOPP/START criteria at each time-point was compared for pre- and post-introduction of a pharmacist using a Mann-Whitney U-test. The mean number of criteria for each time-point within each group was compared using a paired Student's t-test. Results and discussion The demographic characteristics of the participants in the pre- and post-intervention groups were similar. The post-intervention group had numerically less STOPP/START criteria, mean 1·18 (1·37) compared to the pre-intervention group 1·50 (1·41), P = 0·07 at discharge. The pre-intervention group had no significant change in the criteria from admission 1·78 (1·57) to geriatric unit transfer 1·72 (1·54) ( P = 0·37); however, there was a significant decrease from geriatric unit transfer 1·72 (1·54) to discharge 1·50 (1·41) ( P = 0·02). The post-intervention group had a significant decrease from hospital admission 2·30 (1·91) to geriatric unit transfer 1·59 (1·60) ( P < 0·01) and again to discharge 1·18 (1·37) ( P < 0·01). What is new and conclusion Pharmacist participation on the ward round in a specialized geriatric unit resulted in a numerical improvement in prescribing quality as measured by the STOPP/START tool.

The present study is an experimental test of the proposal of the researcher Robert Zajonc. To be suitable for this purpose, laboratory tasks must possess three characteristics. They must have clear-cut accuracy criteria. They must be independently classifiable as either having the correct response in a position of dominance or as eliciting strong, incorrect response tendencies. They must have been independently validated as behavioral indicators of variations in general drive level. The paired-associates tasks developed by the researcher K.W. Spence and his associates meet all three requirements. In the present study individuals learned one of the Spence paired-associates lists either in the presence of a passive audience or without an audience. If Zajonc is correct, then the presence of an audience should produce the same effects upon performance in paired-associates learning that were associated with high scores on the MAS in the Spence studies. Thus, the hypothesis was tested that the List and Audience variables interact so that the presence of an audience tends to improve performance on the noncompetitional list and to impair performance on the competitional list.

- Abstract
We describe two enzyme-linked immunosorbent assays for rotavirus antigen in feces, which were designed to be as sensitive and specific as possible, and easy to use anywhere. Both are indirect methods, using the antibody capture method, but the second assay utilizes a rotavirus group-specific monoclonal "detecting" antibody instead of the hyperimmune polyvalent guinea pig antisera used in the first assay. Both tests were found to be more sensitive than electron microscopy for detecting virus. To develop these tests, solid phase, antiserum production methods, treatment of the test antigen with EDTA, substrate, stability of reagents, and the need for confirmatory "blocking" tests were all examined. The first assay described is that used at present by the World Health Organization for their worldwide diarrheal disease control program.

- Abstract
Clinicians are increasingly required to work and learn interprofessionally, yet few studies explore the nature of being interprofessional. The purpose of this study was to explore the lived experience of clinicians who identify as interprofessional or have an interprofessional identity. Interpretive phenomenological analysis (IPA) was applied as a qualitative research approach and analytical method. Fifteen key informants from a range of professions, settings, and roles were recruited via purposive sampling. Data was collected via semi-structured interviews, observation of participants' day-to-day practice, and review of organizational documents, and analyzed using IPA. Six interdependent Group Experiential Themes were developed: (i) The power of person-centered holistic care, (ii) Learning and growth through curiosity, reflection, and willingness to be vulnerable, (iii) Welcomes, values, and empowers all others, (iv) Trust and mutual respect through belonging and connection, (v) The contribution of background and previous experiences, and (vi) The influence of workplace context. Each Group Experiential Theme had between two and nine sub-themes. Results support the value of understanding and making explicit the concepts that comprise clinician interprofessional identity. The findings can be used to support clinicians, educators, leaders, and policy makers to develop and sustain interprofessional identity, and subsequently cultivate a culture of interprofessional collaborative practice. Future research is needed to further explore the themes, investigate their inter-relationships, and present the concepts that comprise clinician interprofessional identity in a way that is accessible to healthcare professionals and facilitates their integration into practice.

- Abstract
Background: Medication harm affects between 5 and 15% of hospitalised patients, with approximately half of the harm events considered preventable through timely intervention. The Adverse Inpatient Medication Event (AIME) risk prediction model was previously developed to guide a systematic approach to patient prioritisation for targeted clinician review, but frailty was not tested as a candidate predictor variable., Aim: To evaluate the predictive performance of an updated AIME model, incorporating a measure of frailty, when applied to a new multisite cohort of hospitalised adult inpatients., Methods: A retrospective cohort study was conducted at two tertiary Australian hospitals on patients discharged between 1st January and April 31, 2020. Data were extracted from electronic medical records (EMRs) and clinical coding databases. Medication harm was identified using ICD-10 Y-codes and confirmed by senior pharmacist review of medical records. The Hospital Frailty Risk Score (HFRS) was calculated for each patient. Logistic regression analysis was used to construct a modified AIME model. Candidate variables of the original AIME model, together with new variables including HFRS were tested. Performance of the final model was reported using area under the curve (AUC) and decision curve analysis (DCA)., Results: A total of 4089 patient admissions were included, with a mean age ± standard deviation (SD) of 64 years (±19 years), 2050 patients (50%) were males, and mean HFRS was 6.2 (±5.9). 184 patients (4.5%) experienced one or more medication harm events during hospitalisation. The new AIME-Frail risk model incorporated 5 of the original variables: length of stay (LOS), anti-psychotics, antiarrhythmics, immunosuppressants, and INR greater than 3, as well as 5 new variables: HFRS, anticoagulants, antibiotics, insulin, and opioid use. The AUC was 0.79 (95% CI: 0.76-0.83) which was superior to the original model (AUC = 0.70, 95% CI: 0.65-0.74) with a sensitivity of 69%, specificity of 81%, positive predictive value of 0.14 (95% CI: 0.10-0.17) and negative predictive value of 0.98 (95% CI: 0.97-0.99). The DCA identified the model as having potential clinical utility between the probability thresholds of 0.05-0.4., Conclusion: The inclusion of a frailty measure improved the predictive performance of the AIME model. Screening inpatients using the AIME-Frail tool could identify more patients at high-risk of medication harm who warrant timely clinician review., (Copyright © 2024 The Authors.

- Abstract
Introduction: Aspirin is used for venous thromboembolism (VTE) prophylaxis after total hip and knee arthroplasty (THA/TKA). However, its efficacy is unclear in patients with multiple VTE risk factors and at risk of aspirin resistance (AR)., Background and Aims: To determine the prevalence of risk factors for VTE and AR in patients after THA/TKA and to determine the relationship between risk factors and drugs prescribed for thromboprophylaxis., Methods: A retrospective cohort study of elective-THA/TKA in six Australian hospitals over a 1-year period. Medical records were manually reviewed to determine demographics, thromboprophylaxis regimen and presence of risk factors. The relationship between individual and cumulative risk factors with the thromboprophylaxis regimen was determined., Results: In total, 1011 patients were included with a mean (SD) age of 65.9 (±11.0) years, and 56.4% were female. The five most prevalent risk factors were obesity (59.1%), age ≥65 years (58.2%), hypertension (45.3%), dyslipidaemia (35.9%) and diabetes (19.7%). Most patients had ≥1 risk factor for VTE (93.6%) and AR (93.6%), with 49.0% and 35.0% having ≥3 concurrent VTE and AR risk factors, respectively. The only significant relationship between risk factors and drugs was diabetes (P < 0.01). Rivaroxaban was more commonly used as the number of concurrent VTE risk factors increased (P < 0.05)., Conclusion: Patients had a high prevalence of VTE and AR risk factors, suggesting aspirin may not be beneficial in many patients. Only diabetes was linked to the selection of thromboprophylaxis. Patients who received rivaroxaban had a greater average number of VTE risk factors. Guidelines should promote individualised prescribing in higher-risk patients., (© 2024 The Authors.

- Abstract
Introduction: The contribution of medication harm to rehospitalisation and adverse patient outcomes after an acute myocardial infarction (AMI) needs exploration. Rehospitalisation is costly to both patients and the healthcare facility. Following an AMI, patients are at risk of medication harm as they are often older and have multiple comorbidities and polypharmacy. This study aimed to quantify and evaluate medication harm causing unplanned rehospitalisation after an AMI., Methods: This was a retrospective cohort study of patients discharged from a quaternary hospital post-AMI. All rehospitalisations within 18 months were identified using medical record review and coding data. The primary outcome measure was medication harm rehospitalisation. Preventability, causality, and severity assessments of medication harm were conducted., Results: A total of 1,564 patients experienced an AMI, and 415 (26.5%) were rehospitalised. Eighty-nine patients (5.7% of total population; 6.0% of those discharged) experienced a total of 101 medication harm events. Those with medication harm were older (p = 0.007) and had higher rates of heart failure (p = 0.005), chronic kidney disease (p = 0.046), chronic obstructive pulmonary disease (p = 0.037), and a prior history of ischaemic heart disease (p = 0.005). Gastrointestinal bleeding, acute kidney injury, and hypotension were the most common medication harm events. Forty percent of events were avoidable, and 84% were classed as "serious." Furosemide, antiplatelets, and angiotensin-converting enzyme inhibitors were the most commonly implicated medications. The median time to medication harm rehospitalisation was 79 days (interquartile range: 16-200 days)., Conclusion: Medication harm causes unplanned rehospitalisation in 5.7% of all AMI patients (1 in 17 patients; 6.0% of those discharged). The majority of harm was serious and occurred within the first 200 days of discharge. This study highlights that measures to attenuate the risk of medication harm rehospitalisation are essential, including post-discharge medication management., (© 2024 The Author(s). Published by S.

- Abstract
Interprofessional education facilitates collaborative practice, which promotes high-quality patient care and patient safety. Interprofessional education (IPE) experiences within clinical settings provide an opportunity for the development of interprofessional collaborative practice competence. The aim of this systematic review was to review the literature evaluating interprofessional education for health professional students within clinical settings and summarize the behavioral outcomes. Databases searched were PubMed, Embase, Scopus, Web of Science, Taylor & Francis Online, ERIC and PsycINFO. Full-text articles were independently screened by two reviewers and included if agreed. Outcomes were analyzed using Kirkpatrick's model modified for IPE. Studies with behavioral change outcomes were analyzed and synthesized using narrative methods. Included studies provided evidence that IPE experiences in clinical settings can enable students to develop and integrate interprofessional collaborative practice competencies, across diverse types of settings. Key tasks enabling students to achieve these learning outcomes included synchronous patient consultations, collaborative development of integrative health-care plans outside of patient consultations, and participation in socialization with health-care teams. There were limitations in the methodological design of the included studies, with limited use of comparator groups and validated tools, high usage of self-report data and serious risk of bias identified across all quantitative included studies. In conclusion, high-quality research designed to measure the construct of behavioral change is lacking. Such research could further investigate the key tasks in IPE experiences in clinical settings that are necessary for students to develop the range of required collaborative practice competencies and integrate these. This could provide clarification regarding if and how this could be achieved across different types of clinical placements.

- Abstract
Background: Clinical pharmacists have been shown to identify and resolve medication related problems post-discharge, however the impact on patient clinical outcomes is unclear., Aims: To undertake a systematic review to identify, critically appraise and present the evidence on post-discharge hospital clinics that provide clinical pharmacist medication review; report the patient clinical outcomes measured; and describe the activities of the clinical pharmacist., Methods: Published studies evaluating a patient clinical outcome following a post-discharge hospital clinic pharmacy service were included. All studies needed a comparative design (intervention vs control or comparator). Pubmed, Embase, CINAHL, PsycnINFO, Web of Science, IPA and APAIS-Health databases were searched to identify studies. The type of clinic and the clinical pharmacist activities were linked to patient clinical outcomes., Results: Fifty-seven studies were included in the final analysis, 14 randomised controlled trials and 43 non-randomised studies. Three key clinic types were identified: post-discharge pharmacist review alone, inpatient care plus post-discharge review and post-discharge collaborative clinics. The three main outcome metrics identified were hospital readmission and/or representation, adverse events and improved disease state metrics. There was often a mix of these outcomes reported as primary and secondary outcomes. High heterogeneity of interventions and clinical pharmacist activities reported meant it was difficult to link clinical pharmacist activities with the outcomes reported., Conclusions: A post-discharge clinic pharmacist may improve patient clinical outcomes such as hospital readmission and representation rates. Future research needs to provide a clearer description of the clinical pharmacist activities provided in both arms of comparative studies., Competing Interests: I declare there are no conflicts of interest to disclose for the primary author of this review., (© 2023 The Author(s).)

- Abstract
Background: Pharmacists working in general practices provide medication reviews with recommendations to general practitioners (GPs) to optimise medications. We describe a model where the pharmacist is empowered with increased responsibility to implement agreed recommendations through collaborative prescribing., Aim: To assess a collaborative pharmacist prescribing model incorporating increased pharmacist responsibility, for patients with chronic diseases in general practice., Method: This was a pre-test-post-test quasi experimental pilot study using a pharmacist embedded in three Australian general practices. A pharmaceutical care plan was developed with patients and their GP to identify drug related problems (DRPs). The pharmacist discussed recommendations to manage DRPs with the GP and implemented recommendations agreed by the GP and patient over the six-month study period. Outcome measures included acceptance and implementation rate of recommendations made by the pharmacist., Results: The pharmacist made 135 recommendations to optimise medicine use of which 126 (93.3%) were accepted by the GP. There were 105 (83.3%) implemented by the end of the study of which the pharmacist implemented 62 (49.3%)., Conclusion: Compared to other Australian studies using a general practice pharmacist model, this study suggested increased pharmacist responsibility through collaborative prescribing led to high acceptance and implementation rates of recommendations to manage DRPs., (© 2022.

- Abstract
A collaborative pharmacist prescribing model for patients with chronic disease(s) attending Australian general practices: patient and general practitioner perceptions., Background: Pharmacists working in general practice settings are slowly emerging in Australia, with comprehensive medication reviews forming a large part of their role in optimising pharmaceutical care. In Australia, pharmacists are entirely reliant on general practitioners (GPs) accepting and implementing their recommendations to manage drug related problems (DRPs). The next step is a model where the pharmacist takes on responsibility for implementing some of their recommendations., Aim: To investigate patient and general practitioner perceptions of a collaborative model of care where the pharmacist has increased responsibility in assisting the general practitioner manage patients with chronic conditions., Method: Semi-structured, phone and face-to-face interviews were conducted with a purposive sample of patients and GPs respectively. Data were transcribed by a professional transcription service, collated using NVivo 12 Plus and analysed using Braun and Clarke's thematic analysis. Provisional codes were generated and clustered into categories, from which themes were identified., Results: Eighteen interviews were conducted (12 patients, 6 GPs). Four themes were identified from the patient interview data: pharmacist attributes; acknowledgement of the impact of the pharmacist, understanding of the GP-pharmacist collaborative model; relationships with and attitudes towards medicines and health care providers. Four themes were identified from the general practitioner interview data: pharmacist attributes; relationships with pharmacists; impressions on collaboration; impressions of the pharmacist's recommendations. Patients' and GPs' perceptions of the collaborative model of care overall were positive, acknowledging the advantages of a patient-centred, interdisciplinary approach and the potential benefits to patients., Conclusion: The GP-pharmacist collaborative model was viewed favourably by patients and GPs, with some GPs articulating the value in the pharmacist's increased responsibility as they implemented some recommendations to manage DRPs., Competing Interests: The authors have no conflict of interest to declare., (Crown Copyright © 2023 Published by Elsevier Inc.)

- Abstract
Objective: To determine the burden, on the ED, of harm from unintentional adverse drug events (ADEs) in the community., Methods: A retrospective, observational study of 936 randomly selected presentations to a level 6 ED at a principal referral hospital in Brisbane, Australia, in November 2017. Clinical records were screened by a pharmacist, who identified suspected ADEs. All suspected ADEs and a random selection of presentations without ADEs were reviewed by an expert panel, which classified, by consensus: occurrence and type of ADE, contribution of ADE to presentation, severity of harm and preventability of presentation. Medication-related ED presentations (ADE-Ps) and potential ADEs were, respectively, defined as presentations directly attributable to an ADE, and medication events that occurred but did not cause the ED presentation. Descriptive data analysis was performed., Results: The median (interquartile range) age of patients was 40 (27-58) years, with 49.7% (95% confidence interval [CI] 46.5-52.9) being male. The prevalences of ADE-Ps and potential ADEs were 9.2% (95% CI 7.5-11.3) and 5.0% (95% CI 3.8-6.6), respectively. The severity of harm was classified as 'death or likely permanent harm' in 4.7% (95% CI 0.2-9.1) of ADE-Ps, 'temporary harm' (89.5%, 95% CI 83.1-96.0) and 'minimal or no harm' (5.8%, 95% CI 0.9-10.8). Most (79.1%, 95% CI 70.5-87.7) ADE-Ps were preventable., Conclusions: There is a high burden on emergency care because of unintended medication harm in the community. Interventions to reduce such harm are likely to require a co-ordinated primary, acute and public healthcare response. The high proportion of presentations with potential ADEs indicates opportunity for harm mitigation in the ED., (© 2022 Australasian College for Emergency Medicine.)

- Abstract
Interprofessional collaborative practice (IPCP) has been recognized as invaluable in delivering safe, high-quality patient care with finite resources. However, despite a decade of advances in interprofessional (IP) research, policy, and competency frameworks, IPCP does not always occur in practice. One reason may be the influence of a clinician's identity in an IP context. The purpose of this scoping review was to understand the nature of IP identity in healthcare clinicians. The PRISMA framework was used to support a comprehensive search strategy and screening of 1746 articles. Inclusion criteria included original research, theses, and reviews, a primary focus on IP identity or professional identity (PI) in an IP team, and a focus on health professionals, including students transitioning to practice. Ninety-five papers met the eligibility criteria, though once charted, just four of the 95 papers focused on IP identity in clinicians. Three further papers examined shared team identity, 25 papers referred to, but did not focus on IP identity, and the remaining 63 papers explored PI in an IP team. While limited studies on clinician IP identity restrict conclusive findings, patterns were identified to direct further research on the nature of IP identity in clinicians. These include values and beliefs, individual and personal factors, profession and professional experience, education, socialization, context, leadership, and the process of IP identity development. While identity is undeniably central to being a clinician, the values, beliefs, attributes, and experiences that contribute to clinician IP identity, how clinician IP identity develops, and factors that influence IP identity remain unclear. The results of this review highlight the value of further investigation of the nature of IP identity, the interplay between PI and IP identity, and identity in an IP context.

- Abstract
Aspirin, an antiplatelet drug, is commonly used at low doses for numerous indications, including prophylaxis of cardiovascular, neurovascular, and venous thromboembolic events. Due to review articles suggesting that aspirin resistance may result in poorer outcomes, interest in assessing platelet function is increasing. Despite this, platelet function tests are rarely used as part of routine clinical practice and therefore, a basic understanding of these tests may be lacking. Although aspirin resistance can be categorized as clinical or laboratory resistance, determining laboratory resistance is the only way to determine resistance before treatment failure occurs. Therefore, knowledge of platelet assays to determine aspirin resistance is of importance. The following review aims to provide a framework for clinicians to understand the main principles of platelet function tests. This includes comparison of the most frequently used platelet assays to diagnose aspirin resistance, including the basic mechanism, methodology, reference ranges, inter-assay comparison, and their respective clinical considerations when using.

- Abstract
Purpose: To externally evaluate the performance of two European risk prediction models, for identifying patients at high-risk of medication harm, in an Australian hospital setting., Methods: This was a secondary analysis of a pre-existing cohort study described in a recently published study by Falconer et al. (Br J Clin Pharmacol 87(3):1512-1524, 2021) describing the development of a predictive risk model for inpatient medication harm. We retrospectively extracted relevant variables using the electronic health records of general medical and geriatric patients admitted to a quaternary hospital, in Brisbane, over 6 months from July to December 2017. This dataset was used to externally evaluate the two European models, The Brighton Adverse Drug Reaction Risk (BADRI) model by Tangiisuran et al. and a risk model developed by Trivalle et al. The variables were entered into both models and the patients' risk of medication harm was calculated, and compared with actual patient outcomes. Predictive performance was evaluated by measuring area under the receiver operative characteristic (AuROC) curves., Results: The Australian patient cohort included 1982 patients (median age 74 years), of which 136 (7%) patients experienced ≥ 1 medication harm event(s). External evaluation of the two European models identified that both the BADRI and the Trivalle models had reduced predictive performance in an Australian patient cohort, compared with their original studies (AuROC of 0.63 [95% CI: 0.58-0.68] and 0.60 [95% CI: 0.55-0.65], respectively)., Conclusion: Neither model demonstrated sufficient discrimination to warrant further evaluation in our local setting. This is likely a result of variations between the development and the validation cohorts, and the change in healthcare systems over time, and highlights the need for an up-to-date and context-specific risk prediction model., (© 2022.

- Abstract
Discrepancies between the medicines consumed by patients and those documented in the medical record can affect medication safety. We aimed to characterize medication discrepancies and medication regimen complexity over time in a cohort of outpatients with decompensated cirrhosis, and evaluate the impact of pharmacist-led intervention on discrepancies and patient outcomes. In a randomized-controlled trial ( n = 57 intervention and n = 57 usual care participants), medication reconciliation and patient-oriented education delivered over a six-month period was associated with a 45% reduction in the incidence rate of 'high' risk discrepancies (IRR = 0.55, 95%CI = 0.31-0.96) compared to usual care. For each additional 'high' risk discrepancy at baseline, the odds of having ≥ 1 unplanned medication-related admission during a 12-month follow-up period increased by 25% (adj-OR = 1.25, 95%CI = 0.97-1.63) independently of the Child-Pugh score and a history of variceal bleeding. Among participants with complete follow-up, intervention patients were 3-fold less likely to have an unplanned medication-related admission (adj-OR = 0.27, 95%CI = 0.07-0.97) compared to usual care. There was no association between medication discrepancies and mortality. Medication regimen complexity, frequent changes to the regimen and hepatic encephalopathy were associated with discrepancies. Medication reconciliation may improve medication safety by facilitating communication between patients and clinicians about 'current' therapies and identifying potentially inappropriate medicines that may lead to harm.

- Abstract
Background: Medication harm can lead to hospital admission, prolonged hospital stay and poor patient outcomes. Reducing medication harm is a priority for healthcare organisations worldwide. Recent Australian studies demonstrate cardiovascular (CV) medications are a leading cause of harm. However, they appear to receive less recognition as 'high risk' medications compared with those classified by the medication safety acronym, 'APINCH' (antimicrobials, potassium, insulin, narcotics, chemotherapeutics, heparin). Our aim was to determine the scale and type of medication harm caused by CV medications in healthcare., Methods: A narrative review of adult (>16 years) medication harm literature identified from PubMed and CINAHL databases was undertaken. Studies with the primary outcome of measuring the incidence of medication harm were included. Harm caused by CV medications was described and ranked against other medication classes at four key stages of a patient's healthcare journey. Where specified, the implicated medications and type of harm were investigated., Results: A total of 75 studies were identified, including seven systematic reviews and three meta-analyses, with most focussing on harm causing hospital admission. CV medications were responsible for approximately 20% of medication harm; however, this proportion increased to 50% in older populations. CV medications were consistently ranked in the top five medication categories causing harm and were often listed as the leading cause., Conclusion: CV medications are a leading cause of medication harm, particularly in older adults, and should be the focus of harm mitigation strategies. A practical approach to generate awareness among health professionals is to incorporate 'C' (for CV medications) into the 'APINCH' acronym., Plain Language Summary: Patient harm from cardiovascular medications: Background: • Harm from medications can cause poor patient outcomes.• Certain medications have been identified as 'high risk' and are known to cause high rates of harm.• 'High risk' medications are included in medication guidelines used by health professionals.• Cardiovascular medications (e.g. blood pressure and cholesterol medications) are important and have many benefits.• Recent studies have found cardiovascular medications to cause high rates of harm.• Cardiovascular medication harm is often under-recognised in clinical practice.• Some guidelines do not consider cardiovascular medications to be 'high risk'. Method: • This review investigated the extent of harm caused by cardiovascular medications in adults across four healthcare settings:(1) at the time of hospital admission;(2) during hospital admission;(3) after hospital; and(4) readmission to hospital.• Harm caused by cardiovascular medications was ranked against other medication classes.• We investigated the type of cardiovascular medications to cause harm and the type of harm caused. Results: • Seventy-five studies were reviewed across 41 countries.• Cardiovascular medications were ranked within the top five medications to cause harm.• Cardiovascular medications were a leading cause of harm in each healthcare setting investigated.• Harm caused by cardiovascular medications was common in older adults (>65 years).• Cardiovascular medications often caused preventable harm.• Medications to treat high blood pressure and abnormal heart rhythms were the most common causes of harm.• We reported kidney injury, electrolyte changes and low blood pressure as common types of harm. Conclusion: • Increased focus on cardiovascular medications in clinical practice is needed.• Health professionals need to carefully prescribe and frequently review cardiovascular medications, especially in older adults.• Patient and health professional discussions should be based on both the benefits and harms of cardiovascular medications.• Cardiovascular medications should be included in all 'high risk' medication guidelines., Competing Interests: Conflict of interest statement: The authors declare that there is no conflict of interest., (© The Author(s), 2021.)

- Abstract
Objective: To investigate whether integrating pharmacists into general practices reduces the number of unplanned re-admissions of patients recently discharged from hospital., Design, Setting: Stepped wedge, cluster randomised trial in 14 general practices in southeast Queensland., Participants: Adults discharged from one of seven study hospitals during the seven days preceding recruitment (22 May 2017 - 14 March 2018) and prescribed five or more long term medicines, or having a primary discharge diagnosis of congestive heart failure or exacerbation of chronic obstructive pulmonary disease., Intervention: Comprehensive face-to-face medicine management consultation with an integrated practice pharmacist within seven days of discharge, followed by a consultation with their general practitioner and further pharmacist consultations as needed., Major Outcomes: Rates of unplanned, all-cause hospital re-admissions and emergency department (ED) presentations 12 months after hospital discharge; incremental net difference in overall costs., Results: By 12 months, there had been 282 re-admissions among 177 control patients (incidence rate [IR], 1.65 per person-year) and 136 among 129 intervention patients (IR, 1.09 per person-year; fully adjusted IR ratio [IRR], 0.79; 95% CI, 0.52-1.18). ED presentation incidence (fully adjusted IRR, 0.46; 95% CI, 0.22-0.94) and combined re-admission and ED presentation incidence (fully adjusted IRR, 0.69; 95% CI, 0.48-0.99) were significantly lower for intervention patients. The estimated incremental net cost benefit of the intervention was $5072 per patient, with a benefit-cost ratio of 31:1., Conclusion: A collaborative pharmacist-GP model of post-hospital discharge medicines management can reduce the incidence of hospital re-admissions and ED presentations, achieving substantial cost savings to the health system., Trial Registration: Australian New Zealand Clinical Trials Registry, ACTRN12616001627448 (prospective)., (© 2021 AMPCo Pty Ltd.)

- Abstract
Aims: Medication harm has negative clinical and economic consequences, contributing to hospitalisation, morbidity and mortality. The incidence ranges from 4 to 14%, of which up to 50% of events may be preventable. A predictive model for identifying high-risk inpatients can guide a timely and systematic approach to prioritisation. The aim of this study is to develop and internally validate a risk prediction model for prioritisation of hospitalised patients at risk of medication harm., Methods: A retrospective cohort study was conducted in general medical and geriatric specialties at an Australian hospital over six months. Medication harm was identified using International Classification of Disease (ICD-10) codes and the hospital's incident database. Sixty-eight variables, including medications and laboratory results, were extracted from the hospital's databases. Multivariable logistic regression was used to develop the final risk model. Performance was evaluated using area under the receiver operative characteristic curve (AuROC) and clinical utility was determined using decision curve analysis., Results: The study cohort included 1982 patients with median age 74 years, of which 136 (7%) experienced at least one adverse medication event(s). The model included: length of stay, hospital re-admission within 12 months, venous or arterial thrombosis and/or embolism, ≥ 8 medications, serum sodium < 126 mmol/L, INR > 3, anti-psychotic, antiarrhythmic and immunosuppressant medications, and history of medication allergy. Validation gave an AuROC of 0.70 (95% CI: 0.65-0.74). Decision curve analysis identified that the AIME may be clinically useful to help guide decision making in practice., Conclusion: We have developed a predictive model with reasonable performance. Future steps include external validation and impact evaluation., (© 2020 British Pharmacological Society.)

- Abstract
Total hip arthroplasties (THA) and total knee arthroplasties (TKA) confer one of the highest risks for developing venous thromboembolism (VTE) and pharmacological prophylaxis is imperative to help mitigate the risks. Aspirin is the most cost-effective medication for VTE prophylaxis, and its use post-THA/TKA has grown in popularity. Aspirin resistance is categorised as clinical or laboratory resistance with obesity, advancing age, diabetes mellitus, dyslipidaemia and inflammatory diseases identified as risk factors for aspirin resistance. Treatment failure due to aspirin resistance has been reported in cardiovascular and cerebrovascular disease leading to increased rates of mortality and re-embolisation. However, aspirin resistance in patients undergoing a THA/TKA has not been described, nor has there been investigation into the incidence rates or clinical outcomes. The aim of this narrative review is to appraise the concept of aspirin resistance in the context of aspirin use for VTE prophylaxis after THA/TKA surgeries. This is important to investigate as the risk factors for aspirin resistance, including obesity, advancing age, diabetes mellitus, dyslipidaemia and inflammatory diseases, are also risk factors for THA/TKA and risk factors for VTE. The presence of aspirin resistance in patients undergoing orthopaedic surgery may place patients at greater risk of thrombotic events if aspirin is prescribed for VTE prophylaxis. This could further increase the risk of complications associated with VTE and potential long-term consequences such as post-thrombotic syndrome. Future research is required to explore and quantify the rates of aspirin resistance and the clinical outcomes in orthopaedic patients; especially in those patients with these overlapping risk factors for THA/TKA, VTE and aspirin resistance.

- Abstract
Background: Medication harm is experienced by up to 30% of hospitalised patients, of which 7% experience severe harm. Pharmacist review can mitigate this harm. However, in increasingly busy hospitals, with high patient throughput, and scarce resources, there is a need to prioritise patients. Current methods are cumbersome, include many risk factors and are not evaluated in the clinical setting., Objectives: To determine key criteria used by hospital pharmacists and investigate perspectives related to patient prioritisation for potential medication harm in the hospital setting., Methods: This study used two methods; focus groups and a cross-sectional survey of Australian hospital pharmacists. Focus groups were used to identify criteria and perspectives related to prioritisation and were analysed thematically. Criteria from focus groups, and a systematic review, were used to design the survey. The survey was distributed via the Society of Hospital Pharmacists of Australia. The top 10 prioritisation criteria, and associated sub-criteria selected by over 50% of respondents were ranked. Combination of criteria used most frequently on a day-to-day basis were identified., Results: Twenty clinical pharmacists participated in four, one-hour, audio recorded focus groups. Using inductive thematic analysis of transcripts three themes were identified; 1) prioritisation criteria, 2) barriers to, and 3) facilitators of patient prioritisation, with five sub-themes and 26 codes. Pharmacists identified a number of barriers such as a lack of relevant handover information. Organisational demands, such as patient discharge and medications supply also influenced priority and could act as barriers to a pharmacist enacting their prioritisation plan. A total of 231 pharmacists completed the survey. High priority criteria included, renal impairment, use of high-risk medications and therapeutic drug monitoring., Conclusion: Pharmacists described prioritisation as a multifactorial process with a focus on high-risk medications and renal impairment. These findings will inform the development of a predictive risk score for patient prioritisation., (Copyright © 2018 Elsevier Inc. All rights reserved.)

- Abstract
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 R
2 = 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., (Copyright © 2018 Elsevier B.V.

- Abstract
Purpose: The multiplicity in terms and definitions of medication-related harm has been a long-standing challenge for health researchers, clinicians, and regulatory bodies. The purpose of this narrative review was to report the diversity of terms; compare definitions, classifications, and models describing medication harm; and suggest which may be useful in both clinical practice and the research setting., Methods: A narrative review of key studies defining and/or classifying medication harm terminology was undertaken., Results: This review found that numerous terms are used to describe medication harm, and that there is a lack of consistency in current definitions, classifications, and applications. This lack of consistency applied across clinical jurisdictions and regulatory terminologies. A number of limitations in current definitions and classifications were identified. These included the exclusion of key types of medication harm events, ambiguous wording, and a lack of clarity and consensus on subclassifications. In general, there was some overlap in key models from the literature and these were presented to describe similarities and differences., Conclusion: Without uniformity quantifying, comparing, combining, or extrapolating medication harm data, such as a rate of harm in a specific population, is a challenge for those involved in medication safety and pharmacovigilance. There is a pressing need for further discussion and international consensus on this topic. Adoption of standard descriptors by practitioner groups, regulatory and policy organisations would foster quality improvement and patient safety.

- Abstract
Aim: An emerging approach to reducing hospital adverse drug events is the use of predictive risk scores. The aim of this systematic review was to critically appraise models developed for predicting adverse drug event risk in inpatients., Methods: Embase, PubMed, CINAHL and Scopus databases were used to identify studies of predictive risk models for hospitalized adult inpatients. Studies had to have used multivariable logistic regression for model development, resulting in a score or rule with two or more variables, to predict the likelihood of inpatient adverse drug events. The Checklist for the critical Appraisal and data extraction for systematic Reviews of prediction Modelling Studies (CHARMS) was used to critically appraise eligible studies., Results: Eleven studies met the inclusion criteria and were included in the review. Ten described the development of a new model, whilst one study revalidated and updated an existing score. Studies used different definitions for outcome but were synonymous with or closely related to adverse drug events. Four studies undertook external validation, five internally validated and two studies did not validate their model. No studies evaluated impact of risk scores on patient outcomes., Conclusion: Adverse drug event risk prediction is a complex endeavour but could help to improve patient safety and hospital resource management. Studies in this review had some limitations in their methods for model development, reporting and validation. Two studies, the BADRI and Trivalle's risk scores, used better model development and validation methods and reported reasonable performance, and so could be considered for further research., (© 2018 The British Pharmacological Society.)
