ABSTRACT

BACKGROUND: The use of health services is likely to vary among veterans with an accepted disability of post-traumatic stress disorder (PTSD), however, the extent of variation is not known. We aimed to determine the extent and type of health services used by veterans with an accepted disability of PTSD. METHODS: The cohort included veterans who served post 1975, were eligible for all Australian Government Department of Veterans' Affairs funded health services, had PTSD as an accepted disability prior to July 2015 and were alive at the 30 June 2016. Veterans were assigned to groups based on their use of health services using K-means cluster analysis. RESULTS: The cohort comprised five clusters involving 2286 veterans. The largest cluster (43%) were a younger, general practitioner (GP) managed cluster who saw their GP quarterly and the psychiatrist twice a year. The second GP cluster (30%) had higher levels of physical comorbidity. The psychiatrist managed cluster (14%) had a mean of 12 psychiatrist visits and one PTSD hospitalisation in the year. The remaining two clusters involved GP and allied healthcare, but no psychologist care. High levels of antidepressant use occurred in all clusters, ranging from 44% up to 69%. The psychiatrist managed cluster had 47% on antipsychotics and 58% on anxiolytics. CONCLUSION: Our study highlights the heterogeneity in health service use. These results identify the significant health utilisation required for up to one-sixth of veterans with PTSD and the significant role of primary care physicians in supporting veterans with PTSD.

ABSTRACT

BACKGROUND: There is minimal information on the utilisation of Disease Modifying Treatment (DMTs) for multiple sclerosis. The appropriate and safe use of medicines is informed by utilisation studies. Outcomes can inform health interventions to improve appropriate use of medicines and post marketing surveillance activities to improve safety. OBJECTIVE: To evaluate utilisation and treatment patterns of disease modifying treatments (DMTs) for relapsing remitting multiple sclerosis (RRMS). METHODS: A representative sample of the Australian pharmaceutical benefits scheme data were analysed (2006-2016). Demographics of incident users and trends in incident and prevalent users were determined. Individual patient treatment pathways were determined by sequential initiation of medicines in two different periods (2006-2013 and 2014-2019). RESULTS: There were 20,660 patients with at least one dispensing of a DMT for RRMS during the study period (median age 41 years, 75% female). Incident and prevalent use increased by 20% and 88%, respectively. The market was responsive to 13 new listings of DMTs over the study period. Sequential treatment was found for 66% of initiators in 2006-2013 and 28.5% of initiators in 2014-2019. Diverse treatment pathways were found, with 278 and 93 unique sequences in 2006-2013 and 2014-2019, respectively. CONCLUSION: The availability of new DMTs has influenced both initial treatment choice and prevalence of users. Individualised treatment patterns and exposure to multiple medicines over time will challenge traditional pharmacovigilance systems.

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.

ABSTRACT

WHAT IS KNOWN AND OBJECTIVE: Although several studies have identified factors which increase the risk of heat-related illness, few have assessed the contribution of medicines. To address this knowledge gap, our study aimed to assess the risk of hospital admission for dehydration or other heat-related illness following initiation of medicines. METHODS: We conducted a retrospective analysis using prescription event symmetry analysis (PESA) of 6700 veterans with incident hospital admission for dehydration or heat-related illness (ICD-10-AM codes E86, X30, T67), between 1 January 2001 and 30 June 2013. The main outcome measure was first ever hospital admission for dehydration or heat-related illness following initiation of commonly used medicines. RESULTS AND DISCUSSION: A significantly higher risk of incident hospital admission for dehydration or heat-related illness was observed following initiation of anticoagulants, cardiovascular medicines, NSAIDs, antipsychotics, antidepressants and anticholinergic agents. The risk of hospital admission for dehydration or heat-related illness ranged from 1·17 (SSRIs) to 2·79 (ACEI plus diuretic combination product). No significant association was observed between initiation of anticonvulsants, anti-Parkinson's agents, hypnotics, anxiolytics or antihistamines and hospital admission for dehydration or heat-related illness. WHAT IS NEW AND CONCLUSION: Many commonly used medicines were found to be associated with increased risk of hospitalization for dehydration or heat-related illness. Initiation of ACE inhibitors in combination with diuretics had the highest risk. Prescribers and patients should be aware of the potential for medicines to be associated with increased risk of dehydration and heat-related illness.
