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.

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: 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.
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.
Objectives: The aim of this study was to compare effectiveness and safety of low-strength and high-strength direct oral anticoagulants (DOACs) with warfarin in the Australian Veteran population.
Design: Sequential cohort study using inverse probability of treatment weighting (IPTW) and propensity score matching. Initiators of high-strength (apixaban 5 mg, dabigatran 150 mg, rivaroxaban 20 mg) and low-strength DOACS (apixaban 2.
Objective: To determine time to opioid cessation post discharge from hospital in persons who had been admitted to hospital for a surgical procedure and were previously naïve to opioids.
Design, Setting And Participants: Retrospective cohort study using administrative health claims database from the Australian Government Department of Veterans' Affairs (DVA). DVA gold card holders aged between 18 and 100 years who were admitted to hospital for a surgical admission between 1 January 2014 and 30 December 2015 and naïve to opioid therapy prior to admission were included in the study.
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.
Background: The Australian Government Department of Veterans' Affairs (DVA) Veterans' Medicines Advice and Therapeutics Education Services (Veterans' MATES) programme conducted two intervention (March 2009, follow-up intervention June 2012) both of which aimed to reduce hypnotic use among Australian veterans. We evaluated the effectiveness of the interventions, and estimated the associated health consequences.
Methods: Both interventions targeted veterans who had been dispensed hypnotics prior to the intervention.
Objectives: To provide a map of Anatomical Therapeutic Chemical (ATC) Classification System codes to individual Rx-Risk comorbidities and to validate the Rx-Risk Comorbidity Index.
Design: The 46 comorbidities in the Rx-Risk Index were mapped to dispensing's indicative of each condition using ATC codes. Prescription dispensing claims in 2014 were used to calculate the Rx-Risk.
Objectives: To examine the risk of dementia associated with posttraumatic stress disorder (PTSD) and the contribution of antipsychotic use to this risk.
Design: Retrospective cohort study SETTING: Australia. Administrative claims data from the Australian Government Department of Veterans' Affairs were used.
Objective: To evaluate the impact of national multifaceted initiatives to improve use of proton pump inhibitors (PPIs) on the use of PPIs among older Australians.
Design: Interrupted time series analysis using administrative health claims data from the Australian Government Department of Veterans' Affairs (DVA).
Setting: Australia.
Background: Most studies assessing the effect of central nervous system (CNS)-acting medicines on cognitive disturbances have focused on the use of individual medicines. The impact on cognitive function when another CNS-acting medicine is added to a patient's treatment regimen is not well known.
Objective: To determine risk of hospitalization for confusion, delirium, or dementia in older people associated with increasing numbers of CNS-acting medicines taken concurrently, as well as the number of standard doses taken each day (measured as defined daily doses).
Rationale: Interventions asking patients to commit to speaking with their doctor about a health-related issue could be used to improve quality of care.
Objective: To evaluate the impact of commitment questions targeting patients on the uptake of recommended health services within a national quality improvement program (Veterans' MATES).
Methods: Patients targeted in the home medicines reviews (HMRs), dose administration aids (DAAs), renal function testing and diabetes interventions were posted educational information and response forms which asked whether they intended to talk to their general practitioner (GP) about the targeted service.
Introduction. Ophthalmic timolol, a topical nonselective beta-blocker, has the potential to be absorbed systemically which may cause adverse cardiovascular effects. This study was conducted to determine whether initiation of ophthalmic timolol was associated with an increased risk of hospitalisation for bradycardia.
View Article and Find Full Text PDFObjectives: To identify the association between use of multiple anticholinergic medications and risk of hospitalization for confusion or dementia.
Design: Retrospective cohort study conducted over 2 years between July 2010 and June 2012, using administrative claims data from the Australian Department of Veterans' Affairs.
Setting: Australia.
Background: Ranibizumab, a vascular endothelial growth factor (VEGF) inhibitor, is used in the treatment of age-related macular degeneration. Inhibition of VEGF has an anti-angiogenic action and is associated with thrombogenicity, thus, myocardial infarction and ischaemic stroke are potential side effects of VEGF inhibitors.
Objective: Our objective was to assess the association between use of ranibizumab and risk of hospitalisation for ischaemic stroke (IS) and myocardial infarction (MI).
Background: Little is known about the impact of taking multiple psychoactive medicines on the risk of hospitalization for falls.
Objective: To identify the association between multiple psychoactive medicine use and hospitalization for falls.
Methods: A retrospective cohort study was conducted between July 2011 and June 2012 in the Australian veteran population who had been dispensed at least one psychoactive medicine within the previous year.
Background: The Australian Government Department of Veterans' Affairs (DVA) funds an ongoing health promotion based program to improve use of medicines and related health services, which implements interventions that include audit and feedback in the form of patient-specific feedback generated from administrative claims records. We aimed to determine changes in medicine use as a result of the program.
Methods: The program provides targeted patient-specific feedback to medical practitioners.
Background: To compare the results of a new-user cohort study design and the self-controlled case series (SCCS) design using the risk of hospitalisation for pneumonia in those dispensed proton pump inhibitors compared to those unexposed as a case study.
Methods: The Australian Government Department of Veterans' Affairs administrative claims database was used. Exposure to proton pump inhibitors and hospitalisations for pneumonia were identified over a 4 year study period 01 Jul 2007 -30 Jun 2011.
Objective: To compare the demographic, socioeconomic, and medical characteristics of patients who had a General Practitioner Management Plan (GPMP) with those for patients without GPMP.
Methods: Cohort study of patients with chronic diseases during the time period 1 July 2006 to 30 June 2008 using the Australian Department of Veterans' Affairs (DVA) claims database.
Results: Of the 88 128 veterans with chronic diseases included in the study, 23 015 (26%) veterans had a GPMP and 11 089 (13%) had a Team Care Arrangement (TCA).
Objective: To identify the prevalence of potentially preventable medication-related hospitalizations amongst elderly Australian veterans by applying clinical indicators to administrative claims data.
Design And Setting: Retrospective cohort study in the Australian veteran population from 1 January 2004 to 31 December 2008.
Participants: A total of 109 044 veterans with one or more hospitalizations defined by the medication-related clinical indicator set, during the 5-year study period.
