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.

This is especially true for time-to-event outcomes, where limited studies have compared the vast number of modelling approaches available. This study compares prediction accuracy and variable importance measures for four modelling approaches in prediction of time-to-revision surgery following total knee arthroplasty (TKA) and total hip arthroplasty (THA).

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.
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.
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.
Introduction: Medicines acting on the central nervous system can increase the risk of postoperative delirium, but the specific medicines associated with greatest risk remain unclear.
Objectives: We aimed to examine the risk of individual central nervous system-acting medicines used preoperatively on delirium after hip or knee surgery.
Methods: A matched case-control study was conducted using data from the Australian Government Department of Veterans' Affairs.
Introduction: Renal function testing should be performed prior to initiating medicines that require dose adjustment in renal impairment, with ongoing monitoring in continued use, particularly in older people. There is little evidence regarding the extent to which renal function monitoring is performed in older Australians dispensed medicines requiring renal function monitoring.
Objective: The aim of this study was to determine the extent of renal function testing in older people dispensed medicines requiring renal function monitoring.
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.
Cognitive side effects of anticholinergic medications in older adults are well documented. Whether these poor cognitive outcomes are observed in children has not been systematically investigated. We aimed to conduct a systematic review and meta-analysis on the associations between anticholinergic medication use and cognitive performance in children.

Design: A prospective cohort intervention.
Participants: The intervention targeted 52 778 Australian Government's Department of Veterans' Affairs patients aged over 64 years who had risk factors for wound development, and their general practitioners (GPs) (n=14 178).
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.

Methods: A retrospective cross-sectional analysis of the Australian Government Department of Veterans' Affairs (DVA) administrative claims data was conducted. Veterans and their spouses with one or more dementia claims between 1 January 2000 and 30 June 2016, who were aged ≥45 years at the time of the claim and who were still alive and living in the community on 30 June 2017, were included.
Background: The Australian medicines regulator, the Therapeutic Goods Administration (TGA), rescheduled all codeine-containing medicines to be available only on prescription on 1 February 2018. This study was conducted to determine whether use of analgesics changed following codeine re-scheduling to prescription only status, and whether there was a change in the use of codeine preparations and a therapeutic shift to stronger opioids or other analgesics in the Australian veteran population following the change.
Methods: Interrupted time series analysis using Repatriation Pharmaceutical Benefits Scheme (RPBS) claims data from the Australian Government Department of Veterans' Affairs (DVA) for clients with dispensing of opioid and non-opioid analgesics between January 2015 and April 2019.
Aims: To determine the prevalence of potentially inappropriate medication (PIM) use at hospital admission and discharge, and the contribution to hospital admission among residential aged care facility residents with and without dementia.
Methods: We conducted a secondary analysis using data from a multihospital prospective cohort study involving consecutively admitted older adults, aged 75 years or older, who were taking 5 or more medications prior to hospital admission and discharged to a residential aged care facility in South Australia. PIM use was identified using the 2015 Screening Tool for Older Persons' Prescription and 2019 Beers criteria.
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.
Introduction: Many medicines have adverse effects which are difficult to detect and frequently go unrecognised. Pharmacist monitoring of changes in signs and symptoms of these adverse effects, which we describe as medicine-induced deterioration, may reduce the risk of developing frailty. The aim of this trial is to determine the effectiveness of a 12-month pharmacist service compared with usual care in reducing medicine-induced deterioration, frailty and adverse reactions in older people living in aged-care facilities in Australia.

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.
Objectives: One of the outcomes of a medication review service is to identify and manage medication-related problems (MRPs). The most serious MRPs may result in hospitalisation, which could be preventable if appropriate processes of care were adopted. The aim of this study was to update and adapt a previously published set of clinical indicators for use in assessing the effectiveness of a medication review service tailored to meet the needs of Indigenous people, who experience some of the worst health outcomes of all Australians.
View Article and Find Full Text PDFBackground: People with Alzheimer's disease (AD) often have multimorbidity and take multiple medicines. Yet few studies have examined medicine utilization for comorbidities comparing people with and without AD.
Objective: The aim was to investigate the patterns of medication use for comorbidities in people with and without AD.
Objective: To test the association between use of medicines with anticholinergic or sedative properties and physical function, cognitive function, appetite and frailty.
Design, Setting And Participants: This cross-sectional study analysed baseline data collected as part of the Australian Longitudinal Study of Ageing, a population-based cohort of 2087 participants aged 65 years or over living in South Australia.
Main Outcome Measures: Physical function was measured at baseline using measures including hand grip strength, walking speed, chair stands, activities of daily living and instrumental activities of daily living (IADL).
