To test or to not test: A retrospective cross-sectional study on potentially inappropriate use of pathology testing in South Australian hospitals. Am J Clin Pathol 2024; 161:342-348. [PMID: 37975596 PMCID: PMC10988106 DOI: 10.1093/ajcp/aqad153] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/31/2023] [Accepted: 10/10/2023] [Indexed: 11/19/2023] Open
Abstract
OBJECTIVES To measure rates of potentially inappropriate pathology testing in the hospital setting. METHODS Retrospective cross-sectional study in hospital setting from July 2021 to December 2021. We examined 3 potentially inappropriate uses: overordering, selection errors, and unnecessary repeat testing. Overordering included vitamin D and lipids (rarely required in acute hospital care). Selection error was the ratio of iron studies to standalone ferritin requests. Unnecessary repeats included any repeat vitamin D, lipids, iron, or ferritin in an episode of care or C-reactive protein (CRP) repeated within 3 days and N-terminal pro-brain natriuretic peptide (NT-proBNP) within 7 days and repeated previously abnormal CRP and NT-proBNP tests. Costs of inappropriate tests were estimated using the Australian Medicare Benefits Schedules. RESULTS Among 55,904 test requests, 15% (n = 8120) were potentially inappropriate. Vitamin D was frequently ordered (n = 4498), as were lipids (n = 2872). Ratio of iron studies to standalone ferritin was 36. Of 19,233 repeat CRPs, 36% (n = 6947) were within 3 days and 62% (n = 179) of repeat NT-proBNPs were within 7 days of the first test. For initially abnormal tests, 89% of CRPs and 97% of NT-proBNPs remained abnormal. Inappropriate test costs accounted for 12% to 30% of costs. CONCLUSIONS Frequent potential inappropriate use and selection of pathology tests was observed in South Australian hospitals.

A Digitally Enabled, Pharmacist service to detecT medicine harms in residential aged care (nursing home) (ADEPT): protocol for a feasibility study. BMJ Open 2024; 14:e080148. [PMID: 38341209 PMCID: PMC10862280 DOI: 10.1136/bmjopen-2023-080148] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 09/22/2023] [Accepted: 01/30/2024] [Indexed: 02/12/2024] Open
Abstract
INTRODUCTION This feasibility study aims to develop and test a new model of practice in Australia using digital technologies to enable pharmacists to monitor early signs and symptoms of medicine-induced harms in residential aged care. METHODS AND ANALYSIS Thirty residents will be recruited from an aged care facility in South Australia. The study will be conducted in two phases. In phase I, the study team will work with aged care software providers and developers of digital technologies (a wearable activity tracker and a sleep tracking sensor) to gather physical activity and sleep data, as well as medication and clinical data from the electronic medication management system and aged care clinical software. Data will be centralised into a cloud-based monitoring platform (TeleClinical Care (TCC)). The TCC will be used to create dashboards that will include longitudinal visualisations of changes in residents' health, function and medicine use over time. In phase II, the on-site pharmacist will use the centralised TCC platform to monitor each resident's medicine, clinical, physical activity and sleep data to identify signs of medicine-induced harms over a 12-week period.A mixed methods process evaluation applying the RE-AIM (Reach, Effectiveness, Adoption, Implementation, Maintenance) evaluation framework will be used to assess the feasibility of the service. Outcome measures include service reach, changes in resident symptom scores (measured using the Edmonton Symptom Assessment System), number of medication adverse events detected, changes in physical activity and sleep, number of pharmacist recommendations provided, cost analysis and proportion of all pharmacists' recommendations implemented at 4-week, 8-week and 12-week postbaseline period. ETHICS AND DISSEMINATION Ethical approval has been obtained from the University of South Australia's Human Research Ethics Committee (205098). Findings will be disseminated through published manuscripts, conference presentations and reporting to the study funder. TRIAL REGISTRATION NUMBER ACTRN12623000506695.

Abstract
Natural disasters and health emergencies disproportionally affect vulnerable populations causing disruptions to usual care and increasing chronic disease burden. Data and digital technologies are important tools to identify and mitigate indirect effects of emergencies. In this paper, we describe the methods used in the development of a series of digital emergency preparedness interventions to mitigate the direct and indirect consequences of the COVID-19 pandemic in the veteran community in Australia. The case studies demonstrate the use of data for surveillance, patient phenotyping, data-driven decision support and stakeholder communication in primary care. The intervention successfully increased appropriate healthcare use by vulnerable individuals and could be expanded to other populations.

Temporal trends in percutaneous coronary intervention in Australia: A retrospective analysis from 2000-2021. Hellenic J Cardiol 2023:S1109-9666(23)00193-8. [PMID: 37863429 DOI: 10.1016/j.hjc.2023.10.002] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/07/2023] [Revised: 09/27/2023] [Accepted: 10/11/2023] [Indexed: 10/22/2023] Open
Abstract
OBJECTIVE The aim of this study was to describe the trend in percutaneous coronary intervention (PCI) with insertion of a stent in Australia from 2000/01 to 2020/21 and investigate trends in same-day versus non-same-day discharge following PCI. A secondary aim was to compare the rate of coronary artery bypass grafting (CABG) with PCI procedures, while a third aim was to compare marked PCI trend changes with the PCI guidelines during the study period. BACKGROUND PCI with stent deployment is the most common form of interventional treatment for coronary artery disease, and its use has been expanding since 2000. However, there is a lack of descriptive studies of the national trend in Australia. METHODS All procedures for PCI and CABG were extracted across 21 years (2000/01 to 2020/21) from the Australian Institute of Health and Welfare data. Age-standardized rates were calculated using the Australian standard population as of June 2001. The ratio of PCI to CABG procedures was also calculated. Trends for PCI were stratified by age, gender, and same-day or overnight discharge episodes. Linear regression analysis was done to compare the age-standardized rates across different age categories. Segmented regression analysis was performed to ascertain the change in the age-standardized rates of PCI during the study period. Whether the changepoints in the trend were matched with guideline updates was also assessed. RESULTS There were 751 728 PCI procedures in persons aged 30 years and above between 2000/01 and 2020/21. The age-standardized rate for the study period showed that persons aged 60-74 years had a higher rate of procedures (102.7) compared to persons aged 30-59 years (81.3) and 75 years and older (61.8) (P < 0.001). There were two statistically significant changepoints in the overall trend; 2005/06 and 2013/14, matched with the change in PCI guidelines. Despite the lower number of procedures for same-day discharge episodes, there has been an increasing trend since 2014/15. More than two-thirds of all stenting procedures were the insertion of a single stent. PCI to CABG procedure ratio increased from 0.6 in 2000/01 to 1.8 in 2020/21. CONCLUSIONS There was a varying trend in the age-standardized rate of PCI with a peak in 2005/06. The trend appears to be stabilizing in the later part of the study period, but the rate for same-day discharge episodes showed an increasing trend after 2014/15. There is consistency with changepoints in the trend and updated PCI guideline recommendations. The ratio of PCI with insertion of a stent to CABG procedure increased substantially across the study period.

Abstract
INTRODUCTION This study aimed to identify opportunities for clinical decision support targeting medication safety in remote primary care, by investigating the relationship between clinical workflows, health system priorities, cognitive tasks, and reasoning processes in the context of medicines used in people with chronic kidney disease (CKD). METHODS This qualitative study involved one-on-one, semistructured interviews. The participants were healthcare professionals employed in a clinical or managerial capacity with clinical work experience in a remote health setting for at least 1 year. RESULTS Twenty-five clinicians were interviewed. Of these, four were rural medical practitioners, nine were remote area nurses, eight were Aboriginal health practitioners, and four were pharmacists. Four major themes were identified from the interviews: (1) the need for a clinical decision support system to support a sustainable remote health workforce, as clinicians were "constantly stretched" and problems may "fall through the cracks"; (2) reliance on digital health technologies, as medical staff are often not physically available and clinicians-on-duty usually "flick an email and give a call so that I can actually talk it through to our GP"; (3) knowledge gaps, as "it takes a lot of mental space" to know each patient's renal function and their medication history, and clinicians believe "mistakes can be made"; and (4) multiple risk factors impacting CKD management, including clinical, social and behavioural determinants. CONCLUSIONS The high prevalence of CKD and reliance on digital health systems in remote primary health settings can make a clinical decision support system valuable for supporting clinicians who may not have extensive experience in managing medicines for people with CKD.

Correlation of frailty assessment metrics in one-year follow-up of aged care residents: a sub-study of a randomised controlled trial. Aging Clin Exp Res 2023; 35:2081-2087. [PMID: 37452224 PMCID: PMC10520153 DOI: 10.1007/s40520-023-02491-y] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/07/2023] [Accepted: 07/01/2023] [Indexed: 07/18/2023]
Abstract
INTRODUCTION Frailty is increasingly recognised as a dynamic syndrome, with multiple causes, dimensions and consequences. There is little understanding of how those frailty assessment metrics interact over time. The aim of this study was to describe the longitudinal correlation between five frailty metrics, namely multimorbidity, muscular strength, mood alterations, cognitive capacity, and functional capacity in a cohort study of aged care (nursing home) residents. METHODS 248 aged care residents with Frailty Index at baseline of < 0.4 and no dementia were followed for 12 months. A multimorbidity score and an activity of daily living limitation score were created using individual items of the Frailty Index. Muscular strength was measured by grip strength. Cognitive capacity was measured using the Montreal Cognitive Assessment (MoCA) test. Mood alterations were measured using the anxiety/depression screening question from EQ-5D. We analysed the inter-individual correlation at baseline, association between baseline and future change, and within-individual correlation at baseline, 6 and 12 months. RESULTS Population analysis shows that metrics were not associated at baseline. All of the studied metrics at baseline were associated with change in 12 months, with the exception of anxiety/depression scores. Pairwise within-individual correlation was strong between MoCA and grip strength (0.13, p = 0.02) and activity of daily living (- 0.48, p < 0.001), and between activities of daily living and multimorbidity index (0.28, p < 0.001). No within-individual correlation was found between anxiety depression score and other metrics. CONCLUSION The results suggest an interdependence between comorbidities, physical capacity, cognition and activities of daily living in aged care residents. Comprehensive measurement of frailty-related metrics may provide improved understanding of frailty progression at later life stages.

Pharmacists as patient advocates: A series of case studies illustrating the impacts of a regular pharmacist service in residential aged care (nursing homes). EXPLORATORY RESEARCH IN CLINICAL AND SOCIAL PHARMACY 2023; 10:100268. [PMID: 37151371 PMCID: PMC10160770 DOI: 10.1016/j.rcsop.2023.100268] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/19/2023] [Revised: 04/06/2023] [Accepted: 04/12/2023] [Indexed: 05/09/2023] Open
Abstract
Background Medicine-related problems are common in older people living in residential aged care facilities (RACFs). Recognising the significant medicine-related problems, the Australian government has announced a $345 million funding package to employ on-site pharmacists in RACFs starting in 2023. The new on-site pharmacists are to provide a range of clinical services to reduce medicine-related adverse events, promote quality use of medicines, and improve clinical governance and education. Underpinning these services, the authors argue that pharmacists play the critical role as resident advocates. Objective This study aims to demonstrate how pharmacists can enhance their advocacy responsibility within and beyond the clinical environment to not only reduce medicine-related adverse events but also improve residents' overall health and quality of life. Methods This study uses a case series methodology to demonstrate pharmacists' diverse roles in advocating for residents and their families. The case studies were based on participants enrolled in the Reducing Medicine-Induced Deterioration and Adverse Reactions (ReMInDAR) trial, a randomised controlled trial testing the effects of a regular pharmacist service across the Australian RACFs. Results Pharmacists' advocacy ranged from persistence in follow-up with a resident's general practitioner (GP) to ensure the GP was aware that a patient was experiencing bleeding and bruising while on an anticoagulant, to advocating for a new bed for a resident with peripheral oedema who had been sleeping in his chair due to fear of falling out of his current bed. Conclusions Our trial focussed on pharmacists serving as the residents' advocate to improve their overall health and quality of life, rather than just addressing a list of medicine-related problems. The pharmacist model used in the ReMInDAR trial supports pharmacists to work to their full scope of practice, helps guide the Australian government's new on-site pharmacist program, and serves as an exemplar pharmacist in aged care model internationally.

Abstract
BACKGROUND Aged care residents are vulnerable to the harmful effects of medicines; however, data on the prevalence and preventability of adverse medicine events in aged care residents are scarce. AIM To determine the prevalence and preventability of adverse medicine events in Australian aged care residents. METHODS A secondary analysis of data from the Reducing Medicine-Induced Deterioration and Adverse Reactions (ReMInDAR) trial was conducted. Potential adverse medicine events were identified and independently screened by two research pharmacists to produce a short-list of potential adverse medicine events. An expert clinical panel reviewed each potential adverse medicine to determine the likelihood that the event was medicine related (based on the Naranjo Probability Scale criteria). The clinical panel assessed preventability of medicine-related events using Schumock-Thornton criteria. RESULTS There were 583 adverse events due to medicines, involving 154 residents (62% of the 248 study participants). There was a median of three medication-related adverse events (interquartile range [IQR] 1-5) per resident over the 12-month follow-up period. The most common medication-related adverse events were falls (56%), bleeding (18%) and bruising (9%). There were 482 (83%) medication-related adverse events that were preventable, most commonly falls (66% of preventable adverse medicine events), bleeding (12%) and dizziness (8%). Of the 248 residents, 133 (54% of the cohort) had at least one preventable adverse medicine event, with a median of 2 (IQR 1-4) preventable adverse medicine events per resident. CONCLUSION In total, 62% of aged care residents in our study had an adverse medicine event and 54% had a preventable adverse medicine event in a 12-month period.

Using wrist-worn accelerometers to identify the impact of medicines with anticholinergic or sedative properties on sedentary time: A 12-month prospective analysis. Maturitas 2023; 172:9-14.

Abstract
INTRODUCTION Studies have shown that use of medicines with sedative or anticholinergic properties is associated with a decline in physical function; however, the effects have not been quantified, and it is not known how and which specific physical movements are affected. This prospective study quantified the impact of a change in sedative or anticholinergic load over time on 24-hour activity composition. METHODS This study used data collected from a randomised trial assessing an ongoing pharmacist service in residential aged care. The 24-hour activity composition of sleep, sedentary behaviour, light-intensity physical activity, and moderate to vigorous physical activity was derived from 24-hour accelerometry bands. Mixed effect linear models were used to regress the multivariate outcome of 24-hour activity composition on medication load at baseline and at 12 months. A fixed effect interaction between trial stage and medication load was included to test for differing sedative or anticholinergic load effects at the two trial stages. RESULTS Data for 183 and 85 participants were available at baseline and 12 months respectively. There was a statistically significant interaction between medication load and time point on the multivariate outcome of 24-hour activity composition (sedative F = 7.2, p < 0.001 and anticholinergic F = 3.2, p = 0.02). A sedative load increase from 2 to 4 over the 12-month period was associated with an average increase in daily sedentary behaviour by an estimated 24 min. CONCLUSION As sedative or anticholinergic load increased, there was an increase in sedentary time. Our findings suggest wearable accelerometry bands are a possible tool for monitoring the effects on physical function of sedative and anticholinergic medicines. TRIAL REGISTRATION The ReMInDAR trial was registered on the Australian and New Zealand Trials Registry ACTRN12618000766213.

Abstract
Objectives: This paper aimed to review and synthesise the qualitative research evidence on the experiences and perceptions of dementia in Vietnam and among the Vietnamese diaspora.Methods: Systematic searches were conducted in June 2019 using Medline, Embase, Emcare, PsycINFO and Cochrane electronic databases, as well as grey literature. Keywords and Medical Subject Headings [MeSH terms] for dementia and associated terms were combined with keywords for Vietnam and its provinces. Qualitative research articles published in English or Vietnamese were included to examine evidence on the life experiences of Vietnamese people with dementia using thematic analysis.Results: Our searches resulted in 3,940 papers, from which 21 qualitative research studies were included for final analysis. The majority of research has not been undertaken in Vietnam but with the Vietnamese diaspora in Western countries and has taken a cultural perspective to analyses. Research in Western countries has focused on the need for culturally adapted and culturally sensitive models of care. Emerging themes about the life experiences of Vietnamese people with dementia identified from the studies included: many people do not have diagnostic terms for dementia but use the descriptive language of symptoms; stigma was a reported problem and on occasions can be observed in the descriptive language used for people with dementia; cultural and traditional values create both an opportunity and a barrier, supporting compassion, family care and relaxation, but creating barriers to accessing health services or long-term residential care.Conclusions: This is the first systematic review reporting qualitative evidence on the life experiences of people with dementia in Vietnam and among the Vietnamese diaspora. Future research is needed on the voice of people with dementia themselves and their caregivers particularly in Vietnam, and low and middle-income countries with regards to living with dementia, pathways to care from diagnosis, treatment, care and support, additional social care and preparedness for end of life care for people with dementia.

Abstract
BACKGROUND Objective measures for screening, prioritizing, and planning care for frail individuals are essential for appropriate aged care provision. This study evaluates metrics derived from actigraphy measures (captured by wrist accelerometer) as a digital biomarker to identify frail individuals at risk of adverse outcomes, including death, hospitalization, and cognitive decline. METHODS This was a secondary study using data from a randomized controlled trial assessing the effectiveness of an ongoing pharmacist service in residential aged care facilities. Three metrics are studied and compared: the Frailty Index, the daily time spent in light time activity, and the temporal correlation of the actigraphy signal, measured by detrended fluctuation analysis. The association between actigraphy-derived metrics at baseline and adverse events within 12 months (death, cognitive decline, and hospitalizations) was assessed using logistic regression. RESULTS Actigraphy records were available for 213 participants living in aged-care, median age of 85 years. Individuals with higher temporal correlation (activity is less random) were at lower risk of death (Standardized OR: 0.49; 95% CI 0.34, 0.7, p < 0.001) and hospitalization (Standardized OR: 0.57; 95% CI 0.42, 0.77, p < 0.001) in 12 months, but there was no difference in cognitive decline (Standardized OR: 1; 95% CI 0.74, 1.35, p = 0.98). The predictive model that included temporal correlation had an area under the curve of 0.70 (CI 0.60-0.80) for death and 0.64 (CI 0.54-0.72) for hospitalization. CONCLUSION Temporal correlation of the actigraphy signal from aged care residents was strongly associated with death and hospitalization, but not cognitive decline. Digital biomarkers may have a place as an objective, accurate, and low-cost patient metric to support risk stratification and clinical planning.

Abstract
Objectives Large population-based studies examining frailty trajectory found a linear increase in frailty over time. The pattern in which frailty changes over time for an individual person is less well-described. We examined the frailty trajectory of older adults living in aged-care in Australia. Materials and methods This secondary study used data from a randomised controlled trial involving 39 aged-care facilities in Australia. The trial intervention was an on-going pharmacist-led intervention occurring every 8 weeks over 12 months aimed at preventing medicine-induced deterioration and adverse reactions. Frailty was assessed using the Frailty Index. Participants were categorised as non-frail, pre-frail and frail. Individual frailty trajectory over 12 months was visualised using the alluvial plot. Case notes were examined to explore reasons for any rapid transitions in frailty status. Results A total of 248 participants was included. At baseline, 40.3% were non-frail and 59.7% were pre-frail. The proportion of participants who were non-frail and pre-frail decreased over time; 15.7% were frail at 6 months and 23.4% were frail at 12 months. Overall, twenty different combinations of frailty transitions were identified over 12 months. Retrospective analysis of case notes suggest that death or transition from non-frail to frail was often preceded by hospitalisation, falls, medication change or clinically significant deterioration in grip strength or cognition. Conclusion The degree of frailty increased over time, but there were variations in the individual trajectories. Regular monitoring of events that precede changes in frailty status is needed to identify strategies to prevent further deterioration in residents’ conditions.

Abstract
BACKGROUND Monoclonal antibody (mAb) and Fc-fusion protein (FcP) are highly effective therapeutic biologics. We aimed to analyse consumption and expenditure trends in 14 Asia-Pacific countries/regions (APAC) and three benchmark countries (the UK, Canada, and the US). METHODS We analysed 440 mAb and FcP biological products using the IQVIA-MIDAS global sales database. For each year between 2010 and 2020 inclusive, we used standard units (SU) sold per 1000 population and manufacture level price (standardised in 2019 US dollars) to evaluate consumption (accessibility) and expenditure (affordability). Changes of consumption and expenditure were estimated using compound annual growth rate (CAGR). Correlations between consumption, country's economic and health performance indicators were measured using Spearman correlation coefficient. FINDINGS Between 2010 and 2020, CAGRs of consumption in each region ranged from 7% to 34% and the CAGRs of expenditure ranged from 9% to 31%. The median consumption of biologics was extremely low in lower-middle-income economies (0·29 SU/1000 population) compared with upper-middle-income economies (1·20), high-income economies (40·94) and benchmark countries (109·55), although the median CAGRs of biologics consumption in lower-middle-income economies (31%) was greater than upper-middle-income (14%), high-income economies (13%) and benchmark countries (9%). Consumption was correlated with GDP per capita [Spearman's rank correlation coefficient (r) = 0·75, p < 0·001], health expenditure as a percentage of total (r = 0·83, p < 0·001) and medical doctors' density (r = 0·85, p < 0·001). INTERPRETATION There have been significant increases in mAb and FcP biologics consumption and expenditure, however accessibility of biological medicines remains unequal and is largely correlated with country's income level.

Rituximab and Pyoderma Gangrenosum: An Investigation of Disproportionality Using a Systems Biology-Informed Approach in the FAERS Database. Drugs Real World Outcomes 2022; 9:639-647. [PMID: 35933497 DOI: 10.1007/s40801-022-00322-6] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.5] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Accepted: 06/26/2022] [Indexed: 12/01/2022] Open
Abstract
BACKGROUND Studies have found an increased risk of pyoderma gangrenosum associated with rituximab. The structural properties and pharmacological action of rituximab may affect the risk of pyoderma gangrenosum. Additionally, pyoderma gangrenosum is associated with autoimmune disorders for which rituximab is indicated. OBJECTIVE We aimed to determine whether rituximab is disproportionally associated with pyoderma gangrenosum using a systems biology-informed approach. METHODS Adverse event reports were extracted from the US Food and Drug Administration Adverse Event Reporting System (FAERS, 2013-20). The Bayesian Confidence Propagation Neural Network Information Component was used to test for disproportionality. Comparators used to determine potential causal pathways included all other medicines, all medicines with a similar structure (monoclonal antibodies), all medicines with the same pharmacological target (CD20 antagonists) and all medicines used for the same indication(s) as rituximab. RESULTS Thirty-two pyoderma gangrenosum cases were identified, 62.5% were female, with a median age of 48 years. There was an increased association of pyoderma gangrenosum with rituximab compared with all other medicines (exponentiated Information Component 6.75, 95% confidence interval (CI) 4.66-9.23). No association was observed when the comparator was either monoclonal antibodies or CD20 antagonists. Conditions for which an association of pyoderma gangrenosum with rituximab was observed were multiple sclerosis (6.68, 95% CI 1.63-15.15), rheumatoid arthritis (2.67, 95% CI 1.14-4.80) and non-Hodgkin's lymphoma (2.94, 95% CI 1.80-3.73). CONCLUSIONS Pyoderma gangrenosum was reported more frequently with rituximab compared with all other medicines. The varying results when restricting medicines for the same condition suggest the potential for confounding by indication. Post-market surveillance of biologic medicines in FAERS should consider a multi-faceted approach, particularly when the outcome of interest is associated with the underlying immune condition being treated by the medicine of interest.

Pioglitazone use in Australia and the United Kingdom following drug safety advisories on bladder cancer risk: an interrupted time series study. Pharmacoepidemiol Drug Saf 2022; 31:1039-1045. [PMID: 35790047 PMCID: PMC9546180 DOI: 10.1002/pds.5508] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/04/2021] [Revised: 06/09/2022] [Accepted: 07/01/2022] [Indexed: 11/09/2022]
Abstract
PURPOSE National regulators in Australia and the United Kingdom (UK) issued safety advisories on the association between pioglitazone use and bladder cancer in July 2011. The Australian advisory noted that males were at higher risk of bladder cancer than females, while the UK advisory highlighted a new recommendation, suggest careful consideration in the elderly due to increasing risk with age. This study examined whether these differences in the advisories had different age- and sex-based impacts in each country. METHODS Interrupted time series analysis was used to compare pioglitazone use (prescriptions/100,000 population) in Australia and the UK for the 24 months before and 11 months after the July 2011 safety advisories (study period July 2009-June 2012). Separate models were used to compare use by sex and age group (≥65 years vs. <65 years) in each country. RESULTS Pioglitazone use fell in Australia (17%) and the UK (24%) following the safety advisories. Use of pioglitazone fell more for males (18%) than females (16%) in Australia, and more for females (25%) than males (23%) in the UK; however neither difference was statistically significant (Australia P=0.445, UK P=0.462). Pioglitazone use fell to a similar extent among older people than younger people in the UK (23% vs. 26%, P=0.354), and did not differ between age groups in Australia (both 18%, P=0.772). CONCLUSIONS The results indicate that differences in the Australian and UK safety advisories resulted in substantial reductions in pioglitazone use at the population level in both countries, however, differences by sub-groups were not observed.

Hydroxyzine Initiation Following Drug Safety Advisories on Cardiac Arrhythmias in the UK and Canada: A Longitudinal Cohort Study. Drug Saf 2022; 45:623-638. [PMID: 35438459 PMCID: PMC9189086 DOI: 10.1007/s40264-022-01175-2] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.5] [Reference Citation Analysis] [Abstract] [MESH Headings] [Grants] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Accepted: 03/13/2022] [Indexed: 12/20/2022]
Abstract
Introduction Regulatory advisories on hydroxyzine and risk of QT prolongation and Torsade de pointes (TdP) were issued in the UK in April 2015 and Canada in June 2016. We hypothesized patients with risk factors for QT prolongation and TdP, compared with those without risk factors, would be less likely to initiate hydroxyzine in the UK and in British Columbia (BC), Canada, following advisories. Methods We conducted a longitudinal study with repeated measures, and evaluated hydroxyzine initiation in a UK cohort and a concurrent BC control cohort (April 2013–March 2016) as well as in a BC advisory cohort (June 2014–May 2017). Results This study included 247,665 patients in the UK cohort, 297,147 patients in the BC control cohort, and 303,653 patients in the BC advisory cohort. Over a 12-month post-advisory period, hydroxyzine initiation decreased by 21% in the UK (rate ratio 0.79, 95% confidence interval 0.66–0.96) relative to the expected level of initiation based on the pre-advisory trend. Hydroxyzine initiation did not change in the BC control cohort or following the Canadian advisory in the BC advisory cohort. The decrease in hydroxyzine initiation in the UK in the 12 months after the advisories was not significantly different for patients with risk factors compared with those without risk factors. Conclusion Hydroxyzine initiation decreased in the UK, but not in BC, in the 12 months following safety advisories. The decrease in hydroxyzine initiation in the UK was not significantly different for patients with versus without risk factors for QT prolongation and TdP.

The association between exacerbation of chronic obstructive pulmonary disease and timing of paracetamol use: a cohort study in elderly Australians. Respir Res 2022; 23:80. [PMID: 35382818 PMCID: PMC8979782 DOI: 10.1186/s12931-022-02010-z] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/16/2021] [Accepted: 03/29/2022] [Indexed: 12/02/2022] Open
Abstract
Background In elderly populations, paracetamol may be used regularly for conditions such as osteoarthritis. Paracetamol has been associated with respiratory disease through a proposed mechanism of glutathione depletion and oxidative stress. Given that chronic obstructive pulmonary disease (COPD) is frequently co-morbid with osteoarthritis, this study investigated whether the dose and timing of paracetamol exposure may induce COPD exacerbations. Methods The study population was 3523 Australian Government Department of Veterans’ Affairs full entitlement holders who had existing COPD on 1 January 2011, who were dispensed at least one prescription of paracetamol between 1 January 2011 and 30 September 2015, and had no paracetamol dispensed in the 6 months prior to 1 January 2011. The outcome was time to first hospitalisation for COPD exacerbation after initiation of paracetamol. A weighted cumulative exposure approach was used. Results The association between paracetamol exposure and COPD exacerbation was protective or harmful depending on the dose, duration, and recency of exposure. Compared to non-use, current use at the maximum dose of 4 g daily for 7 days was associated with a lower risk (HR = 0.78, 95% CI = 0.67–0.92) and a higher risk after 30 days (HR = 1.27, 95% CI = 1.06–1.52). Risk declined to baseline after 2 months. For past use, there was a short-term increase in risk on discontinuation depending of dose, duration and time since stopping. Conclusions Patients and doctors should be aware of the possible risk of COPD exacerbation with higher dose paracetamol 1 to 6 weeks after initiation or discontinuation, but no increased risk after 2 months.

Effect of an ongoing pharmacist service to reduce medicine-induced deterioration and adverse reactions in aged-care facilities (nursing homes): a multicentre, randomised controlled trial (the ReMInDAR trial). Age Ageing 2022; 51:6572256. [PMID: 35460410 PMCID: PMC9034696 DOI: 10.1093/ageing/afac092] [Citation(s) in RCA: 9] [Impact Index Per Article: 4.5] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/21/2021] [Indexed: 01/04/2023] Open
Abstract
Objective To assess the effectiveness of a pharmacist-led intervention using validated tools to reduce medicine-induced deterioration and adverse reactions. Design and setting Multicenter, open-label parallel randomised controlled trial involving 39 Australian aged-care facilities. Participants Residents on ≥4 medicines or ≥1 anticholinergic or sedative medicine. Intervention Pharmacist-led intervention using validated tools to detect signs and symptoms of medicine-induced deterioration which occurred every 8 weeks over 12 months. Comparator Usual care (Residential Medication Management Review) provided by accredited pharmacists. Outcomes Primary outcome was change in Frailty Index at 12 months. Secondary outcomes included changes in cognition, 24-hour movement behaviour by accelerometry, grip strength, weight, adverse events and quality of life. Results 248 persons (median age 87 years) completed the study; 120 in the interventionand, 128 in control arms. In total 575 pharmacist, sessions were undertaken in the intervention arm. There was no statistically significant difference for change in frailty between groups (mean difference: 0.009, 95% CI: −0.028, 0.009, P = 0.320). A significant difference for cognition was observed, with a mean difference of 1.36 point change at 12 months (95% CI: 0.01, 2.72, P = 0.048). Changes in 24-hour movement behaviour, grip strength, adverse events and quality of life were not significantly different between groups. Point estimates favoured the intervention arm at 12 months for frailty, 24-hour movement behaviour and grip strength. Conclusions The use of validated tools by pharmacists to detect signs of medicine-induced deterioration is a model of practice that requires further research, with promising results from this trial, particularly with regards to improved cognition.

The Extent of Medication-Related Hospital Admissions in Australia: A Review from 1988 to 2021. Drug Saf 2022; 45:249-257. [PMID: 35089582 PMCID: PMC8933367 DOI: 10.1007/s40264-021-01144-1] [Citation(s) in RCA: 26] [Impact Index Per Article: 13.0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Accepted: 12/22/2021] [Indexed: 11/29/2022]
Abstract
Introduction Medication-related problems often lead to patient harm. This paper aims to review the Australian literature to determine the overall incidence, severity and preventability of medication-related hospital admissions, as well as providing a national estimate on their extent and cost. Methods The first part of the paper includes a literature search to identify studies that provided estimates of medication-related problems that caused hospital admissions. Incidence of medication-related hospital admissions, type of medication-related problem contributing to admission (e.g. adverse medicine reaction) and method used to estimate incidence (e.g. chart review) were extracted. Data on severity and preventability of the admissions were extracted where available. The second part of the paper involves use of methodological triangulation to estimate the extent and cost of medication-related hospital admission. Median estimates used to assess medication-related hospital admissions and the 2019–2020 national hospital admissions data were used to calculate the national estimate on the extent of medication-related hospital admission. Costs were also estimated. Results Seventeen studies provided estimates on the extent of medication-related hospital admissions as assessed using medication chart review. The median incidence of 2.5% (interquartile range [IQR] 0.6%) as a proportion of all hospital admissions suggests 275,000 hospital admissions annually in Australia are medication related. The median incidence of 9% (IQR 3.9%) of emergency admissions suggests that 270,000 admissions annually are medication related. Eight studies provided estimates of the extent of medication-related hospital admissions identified from administrative health data; the median incidence of 1.7% with an under-reporting rate of 82% suggests 280,000 hospital admissions annually are medication related. Triangulation of results suggests that at least 250,000 hospital admissions annually in Australia are medication related, with an estimated cost of 1.4 billion Australian dollars (AUD$). Five studies assessed severity, and nine studies assessed preventability. Preventability estimates suggest two-thirds of medication-related hospital admissions are potentially preventable. Conclusions We estimated that 250,000 hospital admissions in Australia are medication related, with an annual cost of AUD$1.4 billion to the healthcare system. Two-thirds of medication-related hospital admissions are potentially preventable. Supplementary Information The online version contains supplementary material available at 10.1007/s40264-021-01144-1.

Implementation and Evaluation of a Digitally Enabled Precision Public Health Intervention to Reduce Inappropriate Gabapentinoid Prescription: Cluster Randomized Controlled Trial. J Med Internet Res 2022; 24:e33873.

Abstract
Background Digital technologies can enable rapid targeted delivery of audit and feedback interventions at scale. Few studies have evaluated how mode of delivery affects clinical professional behavior change and none have assessed the feasibility of such an initiative at a national scale. Objective The aim of this study was to develop and evaluate the effect of audit and feedback by digital versus postal (letter) mode of delivery on primary care physician behavior. Methods This study was developed as part of the Veterans’ Medicines Advice and Therapeutics Education Services (MATES) program, an intervention funded by the Australian Government Department of Veterans’ Affairs that provides targeted education and patient-specific audit with feedback to Australian general practitioners, as well as educational material to veterans and other health professionals. We performed a cluster randomized controlled trial of a multifaceted intervention to reduce inappropriate gabapentinoid prescription, comparing digital and postal mode of delivery. All veteran patients targeted also received an educational intervention (postal delivery). Efficacy was measured using a linear mixed-effects model as the average number of gabapentinoid prescriptions standardized by defined daily dose (individual level), and number of veterans visiting a psychologist in the 6 and 12 months following the intervention. Results The trial involved 2552 general practitioners in Australia and took place in March 2020. Both intervention groups had a significant reduction in total gabapentinoid prescription by the end of the study period (digital: mean reduction of 11.2%, P=.004; postal: mean reduction of 11.2%, P=.001). We found no difference between digital and postal mode of delivery in reduction of gabapentinoid prescriptions at 12 months (digital: –0.058, postal: –0.058, P=.98). Digital delivery increased initiations to psychologists at 12 months (digital: 3.8%, postal: 2.0%, P=.02). Conclusions Our digitally delivered professional behavior change intervention was feasible, had comparable effectiveness to the postal intervention with regard to changes in medicine use, and had increased effectiveness with regard to referrals to a psychologist. Given the logistical benefits of digital delivery in nationwide programs, the results encourage exploration of this mode in future interventions.

Abstract
It is known that younger patients treated with antipsychotics are at increased risk of metabolic events; however, it is unknown how this risk varies according to ethnicity, the class of antipsychotic and the specific product used, and by age group. We conducted a multinational sequence symmetry study in Asian populations (Hong Kong, Japan, Korea, Taiwan and Thailand) and non-Asian populations (Australia and Denmark) to evaluate the metabolic events associated with antipsychotics in both Asian and non-Asian populations, for typical and atypical antipsychotics, and by the subgroups of children and adolescents, and young adults. Patients aged 6-30 years newly initiating oral antipsychotic drugs were included. We defined a composite outcome for metabolic events which included dyslipidemia, hypertension and hyperglycemia. We calculated the sequence ratio (SR) by dividing the number of people for whom a medicine for one of the outcome events was initiated within a 12-month period after antipsychotic initiation by the number before antipsychotic initiation. This study included 346,904 antipsychotic initiators across seven countries. Antipsychotic use was associated with an increased risk of composite metabolic events with a pooled adjusted SR (ASR) of 1.22 (95% CI 1.00-1.50). Pooled ASRs were similar between Asian (ASR, 1.22; 95% CI 0.88-1.70) and non-Asian populations (ASR, 1.22; 95% CI 1.04-1.43). The pooled ASR for typical and atypical antipsychotics was 0.98 (95% CI 0.85-1.12) and 1.24 (95% CI 0.97-1.59), respectively. No difference was observed in the relative effect in children and adolescents compared to young adults. The risk of metabolic events associated with antipsychotics use was similar in magnitude in Asian and non-Asian populations despite the marked difference in drug utilization patterns.

Abstract
Background: This systematic review aims to summarise available patient-reported questionnaires to detect adverse drug reactions (ADRs) that can be utilised by healthcare professionals in clinical practice and to summarise the psychometric properties (validity, reliability, and responsiveness) of the questionnaires. Methods: A systematic literature search was conducted using Medline, Pubmed, Embase, and Emcare databases to screen for articles published between January 2000 and July 2020. Data items regarding validity, reliability, and responsiveness were extracted independently by two authors. The methodological quality was assessed using the COSMIN (Consensus-Based Standards for the Selection of Health Measurement Instruments) checklist. Results: A total of 1563 unique article titles were identified after removing duplicates. Following shortlisting of relevant articles, 19 patient-reported ADR questionnaires were identified. Questionnaires most commonly focused on mental health medications (42.1%, n = 8), followed by general questionnaires applicable to any medication (21.1%, n = 4). Many questionnaires did not report assessing the validity and reliability of the measurement tool. For example, only 11 questionnaires (58%) mentioned assessing content validity, in addition to criterion or construct testing. Conclusion: This systematic review summarised the available patient-reported questionnaires that can be used in research and clinical practice to identify ADRs. Results of this systematic review highlight the need for more robust validity and reliability testing when developing patient-reported ADR questionnaires.

Abstract
BACKGROUND The use of cardiac implantable electronic devices (CIED), which includes pacemakers, implantable cardioverter-defibrillators (ICD), cardiac resynchronisation therapy pacemakers (CRT-P) and cardiac resynchronisation therapy defibrillators (CRT-D) has increased over the past 20 years, but there is a lack of real world evidence on the longevity of these devices in the older population which is essential to inform health care delivery and support clinical decisions. METHODS AND RESULTS We conducted a retrospective cohort study using data from the Australian Government Department of Veterans' Affairs database. The cohort consisted of people who had a CIED procedure between 2005 and 2015. The cumulative risk of generator replacement/reoperations was estimated accounting for the competing risk of death. A total of 16,662 patients were included. In pacemaker recipients with an average age of 85 years, the 5-year risk of reoperation ranged from 2.8% in single chamber, 3.6% in dual chamber to 7.6% in CRT-P recipients, while the 5-year risk of dying with the index pacemaker in situ was 63% in single chamber, 46% in dual chamber and 56% in CRT-P recipients. In defibrillator recipients with an average age of 80 years, the 5-year risk of reoperation ranged from 11% in single chamber, 13% in dual chamber to 24% in CRT-D recipients, while the 5-year risk of dying with the index defibrillator in situ was 46% in single chamber, 40% in dual chamber and 41% in CRT-D recipients. CONCLUSION In this cohort of older patients the 5-year risk of generator reoperation was low in pacemaker recipients whereas up to one in four CRT-D recipients would have a reoperation within 5 years.

Abstract
OBJECTIVE To determine the prevalence of medication-related hospitalisations preceded by potentially suboptimal processes of care in aged care residents. METHOD We conducted a retrospective analysis of administrative claims data from the Australian Government Department of Veterans' Affairs (DVA). We identified all hospital admissions for aged care residents between 1 July 2014 and 30 June 2019. The proportion of hospital admissions preceded by potentially suboptimal medication-related processes of care was determined. RESULTS A total of 18 874 hospitalisations were included, and 46% were preceded by potentially suboptimal medication-related care. One-quarter of fracture admissions occurred in residents at risk of fracture who were not using a medicine to prevent fracture, and 87% occurred in residents using falls-risk medicines. Thirty per cent of heart failure admissions occurred in patients who were not using an angiotensin-converting enzyme inhibitor or angiotensin receptor blocker. CONCLUSION Nearly half of hospital admissions were preceded by potentially suboptimal medication-related processes of care. Interventions to improve use of medicines for aged care residents in these areas are warranted.

Abstract
Background The case-crossover design is suited to medication safety studies but is vulnerable to exposure misclassification. Using the example of tricyclic antidepressants and the risk of hip fracture, we present a data visualisation tool for observing exposure misclassification in case-crossover studies. Methods A case-crossover study was conducted using Australian Government Department of Veterans’ Affairs claims data. Beneficiaries aged over 65 years who were hospitalised for hip fracture between 2009 and 2012 were included. The case window was defined as 1–50 days pre fracture. Control window one and control window two were defined as 101–150 and 151–200 days pre fracture, respectively. Patients were stratified by whether exposure status changed when control window two was specified instead of control window one. To visualise potential misclassification, each subject’s tricyclic antidepressant dispensings were plotted over the 200 days pre fracture. Results The study population comprised 8828 patients with a median age of 88 years. Of these subjects, 348 contributed data to the analyses with either control window. The data visualisation suggested that 14% of subjects were potentially misclassified with control window one while 45% were misclassified with control window two. The odds ratio for the association between tricyclic antidepressants and hip fracture was 1.18 (95% confidence interval = 0.91–1.52) using control window one, whereas risk was significantly increased (odds ratio = 1.43, 95% confidence interval = 1.11–1.83) using control window two. Conclusions Exposure misclassification was less likely to be present with control window one than with an earlier control window, control window two. When specifying different control windows in a case-crossover study, data visualisation can help to assess the extent to which exposure misclassification may contribute to variable results.

Abstract
BACKGROUND AND OBJECTIVES Increasing age, male sex and various chronic conditions have been identified as important risk factors for poor outcomes from COVID-19. The aim of this study was to examine the prevalence of risk factors for poor outcomes due to COVID-19 infection in an older population. METHOD The proportion of the population with one or more risk factors and the prevalence of individual risk factors and multiple risk factors were calculated among Department of Veterans' Affairs (DVA) clients aged ≥70 years. RESULTS There were 103,422 DVA clients included. Of these, 79% in the community and 82% in residential aged care had at least one risk factor for poor outcomes from COVID-19. Hypertension was most prevalent, followed by chronic heart and airways disease. Over half had ≥2 risk factors, and one in five had ≥3 risk factors across multiple body systems. DISCUSSION A substantial proportion of older Australians are at risk of poor outcomes from COVID-19 because of their multimorbid risk profile. These patients should be prioritised for proactive monitoring to avoid unintentional harm due to potential omission of care during the pandemic.

Exploring the association between stroke and acute myocardial infarction and statins adherence following a medicines co-payment increase. Res Social Adm Pharm 2021; 17:1780-1785. [PMID: 33558155 DOI: 10.1016/j.sapharm.2021.01.011] [Citation(s) in RCA: 2] [Impact Index Per Article: 0.7] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/12/2019] [Revised: 11/17/2020] [Accepted: 01/23/2021] [Indexed: 11/18/2022]
Abstract
OBJECTIVES Patient contributions (co-payments) for one months' supply of a publicly-subsidised medicine in Australia were increased by 21% in January 2005 (US$2.73-$3.31 for social security recipients and $17.05-$20.58 for others). This study investigates the relationship between patients' use of statin medication and hospitalisation for acute coronary syndrome and stroke, following this large increase in co-payments. METHODS We designed a retrospective cohort study of all patients in Western Australia who were dispensed statin medication between 2004 and 05. Data for the cohort was obtained from State and Federal linked databases. We divided the cohort into those who discontinued, reduced or continued statin therapy in the first six months after the co-payment increase. The primary outcome was two-year hospitalisation for acute coronary syndrome or stroke-related event. Analysis was conducted using Fine and Gray competing risk methods, with death as the competing risk. RESULTS There were 207,066 patients using statins prior to the co-payment increase. Following the increase, 12.5% of patients reduced their use of statin medication, 3.3% of patients discontinued therapy, and 84.2% continued therapy. There were 4343 acute coronary syndrome and stroke-related hospitalisations in the two-year follow-up period. Multivariate analysis demonstrated that discontinuing statins increased the risk of hospitalisation for acute coronary syndrome or stroke-related events by 18% (95%CI = 0.1%-40%) compared to continuing therapy. Subgroup analysis showed that men aged <70 years were at increased risk of 54-63% after discontinuing statins compared to those continuing, but that women and older men were not. CONCLUSION Discontinuing statin medication after a large increase patient cost contribution was associated with higher rates of acute coronary syndrome and stroke-related hospitalisation in men under 70 years. The findings highlight the importance of continued adherence to prescribed statin medication, and that discontinuing therapy for non-clinical reasons (such as cost) can possibly have negative consequences particularly for younger men.

Abstract
PURPOSE This study aimed to compare the utilization of Alzheimer's disease (AD) treatments, donepezil, galantamine, rivastigmine, and memantine, in Korea with Australia and other countries with universal health coverage. METHODS Reimbursement criteria and the patent status of four AD treatments in Korea and Australia were reviewed. The monthly spending and utilization of the treatments were extracted from the national electronic database in Korea and Australia. The defined daily dose per 1000 elderly population per day (DDD/1000e/day) were calculated from July 2008 to June 2019. Annual cost trends of Norway and England were compared with Korea and Australia. RESULTS With the highest share of the use of donepezil in both countries, the cost and utilization of AD treatments in Korea increased more rapidly and remained higher than Australia. The cost of AD treatments in Korea increased by 15.5% every year during the study period, while the spending of the same drugs in Australia decreased by 10.5% annually. The utilization in DDD/1000e/day of AD treatments in Korea increased by 18.3% annually compared with 1.4% in Australia. When compared with Norway and England, countries with similar universal health coverage (UHC) system and elderly polupation, the cost of AD treatments in Korea was still higher with the opposite trend from other countries. CONCLUSIONS Despite the similar UHC systems, there were considerable differences in the post-market utilization of AD treatments in Korea from Australia and other countries. This results can be attributed to differences in re-assessment system, pricing and reimbursement policies, and prescribing culture. This study provides a baseline to explore more comprehensive cross-country studies on rational use of medicines.

Abstract
OBJECTIVE Educational, and audit and feedback interventions are effective in promoting health professional behaviour change and evidence adoption. However, we lack evidence to pinpoint which particular features make them most effective. Our objective is to identify determinants of quality in professional behaviour change interventions, as perceived by participants. DESIGN We performed a comparative observational study using data from the Veterans' Medicines Advice and Therapeutics Education Services program, a nation-wide Australian Government Department of Veterans' Affairs funded program that provides medicines advice and promotes physician adoption of best practices by use of a multifaceted intervention (educational material and a feedback document containing individual patient information). SETTING Primary care practices providing care to Australian veterans. PARTICIPANTS General practitioners (GPs) targeted by 51 distinct behaviour change interventions, implemented between November 2004 and June 2018. PRIMARY AND SECONDARY OUTCOME MEASURES We extracted features related to presentation (number of images, tables and characters), content (polarity and subjectivity using sentiment analysis, number of external links and medicine mentions) and the use of five behaviour change techniques (prompt/cues, goal setting, discrepancy between current behaviour and goal, information about health consequences, feedback on behaviour). The main outcome was perceived usefulness, extracted from postintervention survey. RESULTS On average, each intervention was delivered to 9667 GPs. Prompt and goal setting strategies in the audit and feedback were independently correlated to perceived usefulness (p=0.030 and p=0.005, respectively). The number of distinct behaviour change techniques in the audit and feedback was correlated with improved usefulness (Pearson's coefficient 0.45 (0.19, 0.65), p=0.001). No presentation or content features in the educational material were correlated with perceived usefulness. CONCLUSIONS The finding provides additional evidence encouraging the use of behaviour change techniques, in particular prompt and goal setting, in audit and feedback interventions.

Abstract
Objective This study assessed the effect of the frequency of general practitioner (GP) visitation in the 12 months before a 21% consumer copayment increase in the Pharmaceutical Benefits Scheme (PBS; January 2005) on the reduction or discontinuation of statin dispensing for tertiary prevention. Methods The study used routinely collected, whole-population linked PBS, Medicare, mortality and hospital data from Western Australia. From 2004 to 2005, individuals were classified as having discontinued, reduced or continued their use of statins in the first six months of 2005 following the 21% consumer copayment increase on 1 January 2005. The frequency of GP visits was calculated in 2004 from Medicare data. Multivariate logistic regression models were used to determine the association between GP visits and statin use following the copayment increase. Results In December 2004, there were 22495 stable statin users for tertiary prevention of prior coronary heart disease, prior stroke or prior coronary artery revascularisation procedure. Following the copayment increase, patients either discontinued (3%), reduced (12%) or continued (85%) their statins. Individuals who visited a GP three or more times in 2004 were 47% less likely to discontinue their statins in 2005 than people attending only once. Subgroup analysis showed the effect was apparent in men, and long-term or new statin users. The frequency of GP visits did not affect the proportion of patients reducing their statin therapy. Conclusions Patients who visited their GP at least three times per year had a lower risk of ceasing their statins in the year following the copayment increase. GPs can help patients maintain treatment following rises in medicines costs. What is known about the topic? Following the 21% increase in medication copayment in 2005, individuals discontinued or reduced their statin usage, including for tertiary prevention. What does this paper add? Patients who visited their GP at least three times per year were less likely to discontinue their statin therapy for tertiary prevention following a large copayment increase. What are the implications for practitioners? This paper identifies the important role that GPs have in maintaining the continued use of important medications following rises in medicines costs.

Abstract
INTRODUCTION AND AIMS Mental health disorders and substance abuse are risk factors that both precede and follow chronic opioid use. We predicted that incident opioid users would have lower rates of mental health comorbidities than chronic opioid users, but that incident chronic opioid users would have lower rates of mental health comorbidities than prevalent chronic users. DESIGN AND METHODS We used administrative health claims data to evaluate differences in lifetime mental health and substance abuse comorbidity profiles of people who were prevalent and incident chronic opioid users, as well as those who used opioids acutely. Results were stratified by age. RESULTS Over 5,188 people were prevalent chronic opioid users at study entry. Of the 10,079 people who initiated opioids, 10.2 per-cent had a subsequent chronic episode (incident chronic) and the remainder stopped within 90 days (incident acute). In prevalent chronic users compared to incident chronic users, rates of depression and anxiety were higher across all age groups (odds ratio (OR) across age groups range from = 1.60, 95 percent confidence interval (CI) = 1.35,1.89, to OR = 6.66, 95 percent CI = 3.02, 14.69) and prevalence of alcohol abuse was higher in those aged 55 to 74 years (OR = 5.11, 95 percent CI = 1.83, 14.24, p = 0.002). Acute users were less likely than incident chronic users to have depression and anxiety in those aged over 74 years (depression OR = 0.82, 95 per-cent CI = 0.70, 0.95; anxiety OR = 0.82, 95% CI 0.70, 0.98). CONCLUSIONS Mental health morbidities commonly associated with chronic opioid use increase in prevalence as chronic use continues.

Abstract
OBJECTIVE Work that has shown a relationship between anxiety and chronic opioid use has not focused on older people specifically, despite the additional risks in older populations. This study aimed to understand whether anxiety prior to opioid initiation increased the likelihood of chronic opioid use over time in persons aged 60 years or older. DESIGN Administrative claims data were used to calculate time between initiation of opioids and a first chronic episode of opioid use. Patients were classified as having a history of anxiety if they were dispensed medicines in the anxiolytics class or had a hospitalization event for anxiety prior to treatment with an opioid. Proportional hazards models were used to compare the likelihood of experiencing a chronic episode of opioid use between those with and without a history of anxiety. RESULTS The cohort was 15,000 persons, of which, 5,076 (34 percent) had history of anxiety. Those with anxiety prior to their first opioid dispensing were 30 percent more likely to have an episode of chronic use after adjustment for age, gender, number of comorbidities, and prior surgery (HR = 1.30, 95% CI = 1.16-1.47). The risk of a chronic episode in patients who had surgery prior to initiation of an opioid was 60 percent greater in those with anxiety compared to no anxiety (HR = 1.60, 95% CI = 1.21-2.11) and 24 percent greater in those with anxiety but no prior surgery (HR = 1.24, 95% CI = 1.08-1.42). CONCLUSIONS A significant proportion of older people will have a chronic episode of opioid use. This risk is increased where a history of anxiety is present.

Abstract
BACKGROUND Poor recognition of medicine-induced dry mouth can have a number of adverse effects, including difficulties with speech, chewing and swallowing dry foods, gum disease, dental caries and oral candidosis. This study examined the prevalence of use of medicines that cause dry mouth and claims for dental services funded by the Department of Veterans' Affairs (DVA) in an Australian cohort. METHODS We used the DVA administrative health claims data to identify persons using medicines that can cause dry mouth at 1st of September 2016 and determine their DVA dental claims in the subsequent year. Results were stratified by gender, residence in community or residential aged cared facility and number of medicines. RESULTS We identified 50 679 persons using medicines known to cause dry mouth. Of these, 72.6% were taking only one medicine that may cause dry mouth, and 21.6% were taking two. Less than half (46.2%) of all people taking at least one of these medicines had a dental claim in the following year. A smaller proportion of women (35.9%) made claims than men (56.9%), χ2 = 2248.77, P < 0.0001. CONCLUSIONS Targeted interventions raising awareness of the relationship between some medicines and dry mouth, and the importance of dental visits are warranted.

Abstract
OBJECTIVE The objective of the review was to synthesize the best available evidence on the safety and effectiveness of pharmacist prescribing on patient outcomes in patients who present to hospital. INTRODUCTION Pharmacist prescribing is legal in many countries. Different models of prescribing include dependent, collaborative and independent. Existing reviews of pharmacist prescribing focus on studies in the community setting, or both community and hospital settings. Other reviews focus on descriptions of current practice or perspectives of clinicians and patients on the practice of pharmacist prescribing. A systematic review on the effects of pharmacist prescribing on patient outcomes in the hospital has not been previously undertaken and is important as this practice can help ease the burden on the healthcare system. INCLUSION CRITERIA Studies with controlled experimental designs comparing pharmacist prescribing to medical prescribing in the hospital setting were included in the review. Primary outcomes of interest included clinical outcomes such as therapeutic failure or benefit, adverse effects, and morbidity or mortality. Secondary outcomes included error rates in prescriptions, medication omissions on the medication chart, time or proportion of International Normalized Ratios in therapeutic range, time to reach therapeutic range, and patient satisfaction. METHODS A comprehensive three-step search strategy was utilized. The search was conducted in January 2017 in eight major databases from database inception. Only studies in English were included. The recommended Joanna Briggs Institute approach to critical appraisal, study selection and data extraction was used. Narrative synthesis was performed due to heterogeneity of the studies included in the review. RESULTS The 15 included studies related to dependent and collaborative prescribing models. In four studies that measured clinical outcomes, there was no difference in blood pressure management between pharmacists and doctors while patients of pharmacist prescribers had better cholesterol levels (mean difference in low density lipoprotein of 0.4 mmol/L in one study and 1.1 mmol/L in another; mean difference in total cholesterol of 1.0 mmol/L) and blood sugar levels (mean difference of fasting blood sugar levels of 15 mg/dL, mean difference of glycosylated hemoglobin of 2.6%). In two studies, pharmacists were better at adhering to warfarin dosing nomograms than doctors (average of 100% versus 62% compliance). In six studies, when prescribing warfarin according to dosing nomograms, equivalent numbers or more patients were maintained in therapeutic range by pharmacist prescribers compared to doctors. The incidence of adverse effects related to anticoagulant prescribing was similar across arms but all six studies were underpowered to detect this outcome. Three studies found that pharmacist prescribers made less prescribing errors (20 to 25 times less errors) and omissions (three to 116 times less omissions) than doctors when prescribing patients' usual medications on admission to hospital or in the preoperative setting. Two studies reported that patients were as satisfied with the services provided by pharmacist prescribers as with doctors. CONCLUSIONS This review provides low to moderate evidence that pharmacists can prescribe to the same standards as doctors. Pharmacists are better at adhering to dosing guidelines when prescribing by protocol and make significantly less prescribing errors when charting patients' usual medications on admission to hospital.

Abstract
BACKGROUND Multimorbidity is common in older patients with heart failure (HF), complicating therapeutic management and increasing the risk of harm. OBJECTIVE This study sought to examine the prevalence of medicines for the treatment of comorbid conditions potentially associated with harm in older people, before and after HF hospitalization. METHODS A retrospective cohort study of older people hospitalized with a primary diagnosis of HF over a 12-month period was conducted using administrative health claims data from the Department of Veterans' Affairs (DVA) Australia. We examined the prevalence of medicines that may exacerbate or worsen HF as defined by the American Heart Association (AHA) and Australian HF clinical guidelines, in the 30 days prior and 120 days before and after discharge for HF. RESULTS A total of 4069 older adults were hospitalized for HF during the study period; almost 60% (n = 2435) received at least one medicine associated with an increased risk of harm before hospitalization, with the majority (66.7%, n = 1623) dispensed in the 30 days prior. A small but significant reduction after hospitalization was observed, but 56% (n = 1638) received at least one of these medicines after hospitalization (p = 0.001). Over one-quarter received two or more medicines before hospitalization, and this only reduced to 22% post-hospitalization (p < 0.0001). CONCLUSIONS Little change in the prescribing of potentially harmful medicines for HF was observed; 56% of older adults received at least one following hospitalization for HF, highlighting the therapeutic complexity of multimorbidity in HF. Use of the AHA list to facilitate identification of potentially harmful medicines, followed by prioritization of treatment goals and appropriate risk mitigation are needed to facilitate reduction in hospitalization for patients with HF with multimorbidity.

Abstract
Background: Risperidone is the only antipsychotic approved in Australia for the management of the behavioural and psychological symptoms of dementia (BPSD). In June 2015, the Australian Government Therapeutic Goods Administration (TGA) amended the indication to restrict use in BPSD to patients with Alzheimer's dementia for a maximum twelve-week duration. We aimed to determine whether the rate and duration of risperidone use for BPSD decreased following the regulatory changes. Methods: we conducted a study using the Australian Government Department of Veterans' Affairs administrative claims data and Pharmaceutical Benefits Scheme (PBS) 10% sample data. We included people aged 65 years or older and compared the rate and duration of risperidone use before and after the TGA labelling changes. Results: There was a sustained decrease in the trend of risperidone use for BPSD following the TGA labelling changes, with a monthly decrease of 1.7% in the aged care population, 0.5% in the community living population and 1.5% in the general older Australian population. Overall, in the 24 months post the TGA changes the reduction in the rate of use of risperidone ranged from 20% to 28% lower than compared to what the rate would have been without the TGA changes. The median duration of use of risperidone in aged-care residents decreased from 338 days in the year prior to the TGA labelling changes, to 240 days per person in the year after the changes. Conclusion: The TGA labelling changes were associated with a significant reduction in the rate of use of risperidone for BPSD in veterans living in both the aged care and community settings, and in the general older Australian population. The labelling changes were also associated with a reduced duration of risperidone use in aged care residents, although for most people the duration of use still exceeded the recommended 12-week maximum duration.

Abstract
Background Internationally, antipsychotics are frequently initiated during hospital admission for older patients and use often continues post-discharge without indication. We located no Australian studies on this topic. Objective to identify the hospital admissions (excluding psychosis) associated with antipsychotic initiation and continuation in older Australians. Setting Australian Government Department of Veterans' Affairs. Method Retrospective analysis of administrative claims data for people admitted to hospital from 1 January 2014 to 31 December 2014, aged ≥ 65 years, who were antipsychotic naïve. Main outcome measure number of admissions associated with antipsychotic initiation, and the major diagnosis groups for these admissions. Where antipsychotics were initiated, we determined the time to cessation of antipsychotics after discharge. Results There were 142,009 hospital admissions for 66,415 people with a median age of 86 years. 921 (0.65%) admissions were associated with antipsychotic initiation, most commonly where the primary diagnoses were for mental and behavioural disorders excluding psychosis (17.8%) and injuries (16%). Fourteen percent of antipsychotic initiations were for primary diagnoses of delirium or dementia. When secondary diagnoses were considered, 55% of antipsychotic initiations were associated with delirium, dementia or both. The median duration of use among people who used antipsychotics was 132 days, and 40% continued use until death or one year follow-up. Conclusion Initiation of antipsychotics during hospital admissions was not frequent in this Australian population. Amongst those who did initiate antipsychotics, for almost half no diagnosis corresponding with an approved indication for use was recorded and long-term use of up to one year was common.

Prevalence and Duration of Use of Medicines Recommended for Short-Term Use in Aged Care Facility Residents. PHARMACY 2019; 7:pharmacy7020055. [PMID: 31174405 PMCID: PMC6631023 DOI: 10.3390/pharmacy7020055] [Citation(s) in RCA: 4] [Impact Index Per Article: 0.8] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/21/2019] [Revised: 06/04/2019] [Accepted: 06/05/2019] [Indexed: 01/16/2023] Open
Abstract
Background: Multiple studies have assessed the appropriateness of the use of medicines for nursing home residents; however, few have included duration of use in their assessment. The aim of this study was to assess the level and duration of use of medications recommended for short-term use in residents of aged care facilities in Australia. Methods: Australian Government Department of Veterans’ Affairs (DVA) administrative claims data were used for this study. Veterans eligible for all health services subsidised by DVA were followed for one year from 1 July 2015 to 30 June 2016. The number of days covered for each medicine was calculated by multiplying the number of prescriptions dispensed during the year by the pack duration for the medicine. The pack duration was calculated by dividing the quantity supplied at each dispensing by the usual number of doses per day in older people according to Australian prescribing guidelines. The proportion of patients using each medicine and the number of days covered during the study period were determined. Results: 14, 237 residents met the inclusion criteria. One in five participants were dispensed antipsychotics, and the median duration of use was 180 days in the one-year period. More than one-third were dispensed a benzodiazepine, and the median duration of use was 240 days in the year. Half were dispensed an opioid analgesic with a median duration of use of 225 days in the year. Fifty-two percent were dispensed proton pump inhibitors with a median duration of use of 360 days in the year. A quarter received an antibiotic recommended for the management of urinary tract infection, with a median duration of use of 14 days in the year. Conclusion: Long-term use of antipsychotics, benzodiazepines, opioid analgesics and proton pump inhibitors is common in aged care residents. Ensuring appropriate duration of use for these medicines is necessary to reduce risk of harm.

Using Post-market Utilisation Analysis to Support Medicines Pricing Policy: An Australian Case Study of Aflibercept and Ranibizumab Use. APPLIED HEALTH ECONOMICS AND HEALTH POLICY 2019; 17:411-417. [PMID: 30362070 DOI: 10.1007/s40258-018-0440-4] [Citation(s) in RCA: 4] [Impact Index Per Article: 0.8] [Reference Citation Analysis] [Abstract] [MESH Headings] [Grants] [Track Full Text] [Subscribe] [Scholar Register] [Indexed: 06/08/2023]
Abstract
OBJECTIVES To describe how post-market utilisation analysis in Australia informs cost-effectiveness assessment and pricing decisions, using aflibercept and ranibizumab as case studies. METHODS Pharmaceutical claims were used to identify initiators of aflibercept and ranibizumab in the year after aflibercept-listing (December 2012), and ranibizumab initiators in the year before aflibercept listing. The dispensing rates for each cohort were calculated, and their demographic and clinical characteristics compared using Kruskal-Wallis tests. RESULTS Aflibercept and ranibizumab each accounted for half the age-related macular degeneration market following aflibercept listing. Aflibercept initiators had similar dispensing rates to ranibizumab initiators in the pre- and post-aflibercept era (~ three scripts during the first 90 days, and eight to nine scripts during the following 12 months). All cohorts were similar in terms of their age, sex, residential aged-care status and geographic remoteness, and no differences were observed in their overall co-morbidity scores and history of thromboembolic events. CONCLUSIONS Contrary to clinical trial protocols, post-market utilisation research for ranibizumab and aflibercept demonstrates equivalent use in practice in terms of dose frequency, and the demographic and clinical characteristics of initiators. This supports Australia's decision to pay the same price for each rather than giving a premium to aflibercept. Many other countries are likely overpaying for aflibercept if their utilization patterns are similar to Australia's, and could benefit from incorporating routine utilisation assessment.
