Time trends in cancer incidence in Australian people living with HIV between 1982 and 2012.

The aim of the study was to describe time trends in cancer incidence in people living with HIV (PLHIV) in Australia between 1982 and 2012. A population-based prospective study was conducted using data linkage between the national HIV and cancer registries. Invasive cancers identified in PLHIV were grouped into AIDS-defining cancers (ADCs), infection-related non-ADCs (NADCs), and non-infection-related NADCs. Crude and age-standardized incidence rates of cancers were calculated and compared over five time periods: 1982-1995, 1996-1999, 2000-2004, 2005-2008 and 2009-2012, roughly reflecting advances in HIV antiretroviral therapy. Standardized incidence ratios (SIRs) compared with the Australian general population were calculated for each time period. Generalized linear models were developed to assess time trends in crude and age-standardized incidences. For ADCs, the crude and age-standardized incidences of Kaposi sarcoma and non-Hodgkin lymphoma substantially declined over time (P-trend <0.001 for all) but SIRs remained significantly elevated. For infection-related NADCs, there were significant increases in the crude incidences of anal, liver and head and neck cancers. Age-standardized incidences increased for anal cancer (P-trend = 0.002) and liver cancer (P-trend <0.001). SIRs were significantly elevated for anal cancer, liver cancer and Hodgkin lymphoma. For non-infection-related NADCs, the crude incidence of colorectal, lung and prostate cancers increased over time, but age-standardized incidences remained stable. Continuous improvements and high coverage of antiretroviral therapy have reduced the incidence of ADCs in PLHIV in Australia. Clinical monitoring of anal and liver cancers in people living with HIV should be performed, given the increasing incidence of these cancers.

Lifestyle Parameters in Patients with Diabetes Mellitus and in the General Adult Population-Trends over Five Years: Results of the Austrian National Health Interview Series.

Background: Not smoking, performing >150 min of aerobic physical activity (PA) and muscle strengthening exercises/week, and consuming >5 portions of fruit and vegetables/day are lifestyle recommendations for both the general population and people with diabetes mellitus (DM). Methods: A total of 15,771 and 15,461 persons from the Austrian Health Interview Surveys 2014 and 2019, respectively, including 4.9% and 6.0% of people with DM, were analysed in terms of their smoking, PA, and nutritional behaviours. Logistic regression models were performed for the lifestyle factors, adjusted for socio-demographic and health-related factors. Adjusted interactions between the survey year and DM on the lifestyle factors were computed. Results: The proportions of smokers were 23.9% and 20.2%, of people complying with the PA recommendations were 24.9% and 21.4%, and with fruit and vegetables recommendations were 7.1% and 5.5%, respectively, with significantly lower proportions of smokers and persons complying with the PA recommendations among people with DM. The fully adjusted odds ratios (95% confidence interval) for people with DM were 1.09 (0.94–1.26), 1.44 (1.23–1.69), and 0.90 (0.71–1.13) for smoking, not complying with PA recommendations, and not complying with fruit and vegetables recommendations, respectively. The proportion of people complying with PA recommendations decreased to a greater extent (p < 0.001) in people with DM (16.5% to 8.3%) compared to people without DM (25.3% to 22.3%). Conclusion: Diabetogenic lifestyle behaviours increased in the general Austrian population in recent years, which was especially true for people with DM regarding PA.

Contraception decision making by Culturally and Linguistically Diverse (CALD) Australian youth: an exploratory study

ABSTRACT Context Culturally and Linguistically Diverse (CALD) youth may become early parents, with some aspiring to parenthood. Yet, the factors that influence CALD youths contraceptive decision-making are less well known, although important for designing appropriate contraception use support programmes for this population. This study aimed to explore the contraception decision-making patterns of CALD Australian youth, in-addition to investigating the factors that influence their use of contraception services. Methods We conducted focus groups with 27 CALD youth (ages 16-24) to explore their 1) their contraception use 1) decision-making, 2) information sources, and 3) priority services. For the data synthesis, we utilized thematic analysis to characterize the CALD youth contraception use orientation. Results Three themes emerged from the data: 1) the prevalent use of fail-safe contraception methods to minimize personal anxiety, 2) the reliance on online rather than in-person information sources, and 3) the importance to minimize risk for social stigma from use of contraception. Conclusions CALD Australian youth reported being competent in self-managing their contraception use decisions. Contraption decision support for CALD youth should address their anxieties about the risk of contraception failure and concerns regarding social stigmas. KEY POINTS What is already known: (1) Australian young females from racial and language minority background communities become parents at younger ages than those from the general Australian population. (2) Some look forward to becoming parents earlier rather than later in their lives. What this topic adds: (1) We unraveled decision making processes and tools the teenagers prefer to use outside conventional understandings. (2) Cultural psychology beliefs rooted in family social protections are an overriding decision influence in contraception choices. (3) Peers were less trusted partners in sexual decisions compared to use of online services.

Normal limits for oscillometric bronchodilator responses and relationships with clinical factors.

IntroductionWe aimed to determine normal thresholds for positive bronchodilator responses for oscillometry in an Australian general population sample aged ≥40 years, to guide clinical interpretation. We also examined relationships between bronchodilator responses and respiratory symptoms, asthma diagnosis, smoking and baseline lung function.MethodsSubjects recruited from Sydney, Melbourne and Busselton, Australia, underwent measurements of spirometry, resistance (Rrs6) and reactance (Xrs6) at 6 Hz, before and after inhalation of salbutamol 200 μg. Respiratory symptoms and/or medication use, asthma diagnosis, and smoking were recorded. Threshold bronchodilator responses were defined as the fifth percentile of decrease in Rrs6 and 95th percentile increase in Xrs6 in a healthy subgroup.ResultsOf 1318 participants, 1145 (570 female) were analysed. The lower threshold for ΔRrs6 was −1.38 cmH2O·s·L−1 (−30.0% or −1.42 Z-scores) and upper threshold for ΔXrs6 was 0.57 cmH2O·s·L−1 (1.36 Z-scores). Respiratory symptoms and/or medication use, asthma diagnosis, and smoking all predicted bronchodilator response, as did baseline oscillometry and spirometry. When categorised into clinically relevant groups according to those predictors, ΔXrs6 was more sensitive than spirometry in smokers without current asthma or chronic obstructive pulmonary disease (COPD), ∼20% having a positive response. Using absolute or Z-score change provided similar prevalences of responsiveness, except in COPD, in which responsiveness measured by absolute change was twice that for Z-score.DiscussionThis study describes normative thresholds for bronchodilator responses in oscillometry parameters, including intra-breath parameters, as determined by absolute, relative and Z-score changes. Positive bronchodilator response by oscillometry correlated with clinical factors and baseline function, which may inform the clinical interpretation of oscillometry.

Using Community Based Research Frameworks to Develop and Implement a Church-Based Program to Prevent Diabetes and Its Complications for Samoan Communities in South Western Sydney.

Pasifika communities bear a disproportionate burden of diabetes compared to the general Australian population. Community-based participatory research (CBPR), which involves working in partnership with researchers and communities to address local health needs, has gained prominence as a model of working with underserved communities. This paper describes how Le Taeao Afua (LTA) Samoan diabetes prevention program was underpinned by two CBPR frameworks to develop a culturally tailored church-based lifestyle intervention to prevent diabetes and its complications in the Australian Samoan community. The name LTA, which means ‘a new dawn,’ was chosen by the community to signify a new dawn without diabetes in the Australian Samoan community. Strategies for engaging with the Australian Samoan community in South Western Sydney are discussed mapped to the key principles from the CBPR frameworks. In particular, this paper highlights the steps involved in building relationships with Samoan community leaders and the vital role of community activators and peer support facilitators in the success of delivering the program. Lessons learnt, such as the importance of church and maintaining a Samoan way of life in daily activities, and processes to build effective partnerships and maintain long-term relationships with the Australian Samoan community, are also discussed. Our paper, through providing a case example of how to apply CBPR frameworks, will help guide future community-based health promotion programs for underserved communities.

177Physical functional limitations and psychological distress in people with and without colorectal cancer

Abstract Background This study aims to quantify physical disability and psychological distress in people with and without colorectal cancer (CRC). Methods Questionnaire data (2006-2009) from 267,153 Australian general population members aged ≥45 years participating in the 45 and Up Study (n = 213,231 following exclusions) were linked to cancer registry and hospital admission data, to ascertain CRC status. Modified Poisson regression estimated adjusted prevalence ratios (PRs) for physical disability and psychological distress in participants with versus without CRC. Results Compared with participants without CRC (n = 210,836), CRC survivors (n = 2,395) had significantly higher disability prevalence (11.9% versus 19.5%, respectively): PR = 1.11 (95%CI=1.03-1.20); and a similar prevalence of distress (23.1% versus 20.2%): PR = 1.03 (0.94-1.20). Adverse outcomes were associated with certain clinical characteristics. Compared to participants without CRC, CRC survivors diagnosed 5-&amp;lt;10 and ≥10 years, with regional spread and without recent cancer treatment had similar outcomes; survivors with metastatic CRC and recent treatment had 30-60% higher prevalence of disability and distress. Compared to participants with neither CRC nor disability, PRs for distress were 4.71 (4.22-5.26) for those with disability and CRC and 4.22 (4.13-4.31) for those with disability without CRC. Conclusions Physical disability is elevated in CRC survivors. Psychological distress is elevated 4- to 5-fold with disability, regardless of CRC diagnosis, with lesser increases around diagnosis and treatment. Key message CRC survivors with less advanced disease and who have not been recently diagnosed or treated have physical disability and psychological distress comparable to the general population. Survivors with disability are at particularly high risk of distress.

Are We All Equally Persuaded by Procedural Justice?

A growing number of empirical studies has sought to explore differences in the effectiveness of the procedural justice model across people. Much of this new evidence points at the procedural justice association with both legitimacy and compliance being largely invariant. Here we expand the analysis of this procedural justice ‘invariance thesis’ by introducing a novel life-course perspective to the debate. Specifically, we focus on the variability of the procedural justice effect within individuals across time. To do so, we use mixed effects structural equation models and longitudinal data from a sample of 1,354 young offenders in the US reporting perceptions of the police, and a sample of 511 subjects of the Australian general population reporting on the tax authority. We find the procedural justice within-person association with legitimacy to be highly variant across individuals, which can be negative for more than 10% of subjects in the two samples used, while for at least another 11% of participants the relationship is twice as strong as the average or stronger. We also find variability in the within-person association with compliance; however, this is only the case for a specific measure of procedural justice in the sample of young offenders. These results question the ‘invariance thesis’. Compliance, and especially perceptions of institutional legitimacy, cannot be expected to change uniformly across all subgroups of the population in line with their perceptions of the procedural just actions of those institutions.

Grey nomads with diabetes self-management on the road - a scoping review.

This scoping literature review explored the characteristics and behaviours of a subset of Australia's older population: 'grey nomads', many who live and travel with type 1 or 2 diabetes mellitus. Grey nomads are people aged more than 55 years, who travel in caravans or motorhomes for extended periods of time around rural and remote areas of Australia. Grey nomads are challenging the established view of ageing in Australia by their lifestyle choices, which include social and economic contribution, independence and furthering of personal fulfilment. However, some evidence suggests that grey nomads experience health issues while in rural locations, which exerts a significant burden on already under-resourced Australian rural health services. This review seeks knowledge on grey nomads' self-management of diabetes while travelling, with the aim of understanding their experiences and identifying support services and strategies that would facilitate improved self-management. Furthermore, this review seeks knowledge of how Australia's rural and remote health services support the nomads with diabetes and the influence of this burgeoning population on such services. A scoping review methodology provided the methods to map the current evidence concerned with this broad and complex topic. A systematic six-step framework was adopted: identifying the research question; identifying relevant literature; selecting studies; charting the findings; collating, summarising and reporting results; and a final consultation. The grey nomads in this review travelled long distances through the often-harsh Australian countryside where they sought, privacy, isolation, self-sufficiency and a closeness with nature. Although their motivations included life- and health-enhancing experiences, most grey nomads travelled with at least one chronic health condition, which they did not consider as a barrier to adopting a grey nomad lifestyle. However, many were under-prepared for their health needs when in rural or remote Australia. Specific literature concerning grey nomads and self-management of diabetes was not found but salient aspects of diabetes self-management were identified and included a well-developed relationship with their diabetes healthcare provider; a relationship that relied on ongoing communication and support. When travelling, the ability to form or sustain supportive relationships with local health care providers was limited due to sparseness of rural services and the perceived transient nature of the relationship. Increasingly, grey nomads utilised digital technology via telemedicine or social media sites for information and advice on health issues. The local pharmacies in rural and remote locations were also identified as sources of support and services. The literature showed that the grey nomad population had a similar distribution of chronic illness, including diabetes, to that of the general Australian population, but very little was published about how they self-manage conditions when in remote locations where healthcare services were limited. The emerging roles of digital technology and development opportunities for pharmacists offer new and innovative avenues to support grey nomads with diabetes while travelling in rural and remote Australia.

How can dementia diagnosis and care for Aboriginal and Torres Strait Islander people be improved? Perspectives of healthcare providers providing care in Aboriginal community controlled health services

BackgroundAboriginal and/or Torres Strait Islander people experience dementia at a rate three to five times higher than the general Australian population. Aboriginal Community Controlled Health Services (ACCHSs) have a critical role to play in recognising symptoms of cognitive impairment, facilitating timely diagnosis of dementia, and managing the impacts of dementia. Little is known about the barriers and enablers to Aboriginal people receiving a timely dementia diagnosis and appropriate care once diagnosed.This study aims to explore, from the perspective of healthcare providers in the ACCHS sector across urban, regional and remote communities, the barriers and enablers to the provision of dementia diagnosis and care.MethodsA qualitative study involving semi-structured interviews with staff members working in the ACCHS sector. Aboriginal Health Workers, General Practitioners, nurses, practice or program managers, and Chief Executive Officers were eligible to participate. Consenting ACCHS staff completed a telephone interview administered by a trained interviewer. Interviews were audio-recorded, transcribed, and analysed using qualitative content analysis.ResultsSixteen staff from 10 ACCHSs participated. Most participants perceived their communities had a limited understanding of dementia. Symptoms of dementia were usually noticed by the GP or another healthcare worker at the ACCHS who had an ongoing relationship with the person. Most participants reported that their service had established referral pathways with either hospital-based geriatricians, geriatricians located with aged care assessment teams, or specialists who visited communities periodically. Key enablers to high quality dementia care included the use of routine health assessments as a mechanism for diagnosis; relationships within communities to support diagnosis and care; community and family relationships; comprehensive and holistic care models; and the use of tailored visual resources to support care. Key barriers to high quality care included: denial and stigma; dementia being perceived as a low priority health condition; limited community awareness and understanding of dementia; lack of staff education and training about dementia; and numerous gaps in service delivery.Conclusions Substantially increased investments in supporting best-practice diagnosis and management of dementia in Aboriginal communities are required. ACCHSs have key strengths that should be drawn upon in developing solutions to identified barriers to care.

Uptake, barriers and correlates of influenza vaccination among people who inject drugs in Australia

BackgroundComorbid chronic health conditions place people who inject drugs (PWID) at risk of severe health outcomes after influenza infection. However, little is known about the uptake, barriers and correlates of influenza vaccination among PWID. MethodsDuring structured surveys, 872 PWID reported whether they had received an influenza vaccination during the last year (disaggregated as pre- or post-March 2020 to ascertain current season vaccine uptake), and if not, the barriers to vaccination. Logistic regression was used to examine demographic, drug use, health and service engagement correlates of vaccine uptake. ResultsThirty-nine percent of participants reported past-year influenza vaccination, with one-quarter (24 %) vaccinated in the current season. The main barriers to vaccination were motivation-based, with few citing issues relating to affordability, supply or perceived stigma. Opioid agonist therapy in the past six months was significantly associated with vaccination. ConclusionsInfluenza vaccine uptake was lower among PWID than the Australian general population. Provision of the vaccine at services commonly accessed by PWID may increase uptake.

Excess short-term mortality in noncritical patients with atrial fibrillation presenting to the emergency department.

BackgroundMortality data of non-critically ill patients presenting with symptomatic atrial fibrillation to an emergency department are scarce. We aimed to analyze the short-term mortality of these patients compared with that of the general Austrian population.Design/methodsThis study analyzed a consecutive series of non-critically ill adults presenting to the emergency department at the Medical University of Vienna between 2012 and 2016 with complaints related to atrial fibrillation. The study outcome was mortality during the observation period. Age-specific and sex-specific mortality rates per 100 person-years were calculated and compared with the mortality rates of the Austrian population during the same period.ResultsIn total, 1754 patients with atrial fibrillation (43.1% female) were included in the study. During a median follow-up of 25 months, 248 of these patients died. Observed mortality rates were 7.8 per 100 person-years for females (95% confidence interval, CI 6.6–9.5) and 5.9 per 100 person-years for males (95% CI 5.0–7.1). Age-adjusted and sex-adjusted mortality rates were 2.8 (95% CI 2.3–3.3) and 2.7 (95% CI 2.2–3.2) per 100 person-years, respectively. Mortality rates for the Austrian population were 1.1 per 100 person-years for both females and males. Corresponding standardized mortality ratios were 2.5 for females (95% CI 2.1–3.0) and 2.4 for males (95% CI 2.0–2.9).ConclusionThe short-term mortality of patients with symptomatic atrial fibrillation presenting to the emergency department was substantially higher compared with the general Austrian population.Supplementary InformationThe online version of this article (10.1007/s00508-021-01895-y) contains supplementary material, which is available to authorized users.

Switching, Persistence and Adherence to Statin Therapy: a Retrospective Cohort Study Using the Australian National Pharmacy Data.

Statins are widely prescribed for the primary and secondary prevention of cardiovascular disease (CVD), but their effectiveness is dependent on the level of adherence and persistence. This study aimed to explore the patterns of switching, adherence and persistence among the Australian general population with newly dispensed statins. A retrospective cohort study was conducted using a random sample of data from the Australian national prescription claims data. Switching, adherence to and persistence with statins were assessed for people starting statins from 1 January 2015 to 31 December 2019. Switching was defined as either switching to another intensity of statin, to another statin or to a non-statin agent. Non-persistence to treatment was defined as discontinuation (i.e. ≥90days with no statin) of coverage. Adherence was measured using proportion of days covered (PDC), and patients with PDC < 0.80 were considered non-adherent. Cox proportional hazard models were used to compare discontinuation, switching and reinitiation between different statins. A cohort of 141,062 people dispensed statins and followed over a median duration of 2.5years were included. Of the cohort, 29.3% switched statin intensity, 28.4% switched statin type, 3.7% switched to ezetimibe and in 2.7%, ezetimibe was added as combination therapy during the study period. Overall, 58.8% discontinued statins based on the 90-day gap criteria, of whom 55.2% restarted. The proportion of people non-adherent was 24.0% at 6 months to 49.0% at 5 years. People on low and moderate intensity statins were more likely to discontinue compared to those on high-intensity statins (hazard ratio [HR] 1.20, 95% confidence interval [CI] 1.09-1.31), (HR 1.28, 95%CI 1.14-1.42), respectively. Compared to maintaining same statin type and intensity, switching statins, which includes up-titration (HR 0.77, 95%CI 0.70 to 0.86) was associated with less likelihood of discontinuation after reinitiation. Long-term persistence and adherence to statins remains generally poor among Australians, which limits the effectiveness of these medicines and the consequent health impact they may provide for individuals (and by extension, the population impact when poor persistence and adherence is considered in the statin-taking population). Switching between statins is prevalent in one third of statin users, although any clinical benefit of the observed switching trend is unknown. This, combined with the high volume of statin prescriptions, highlights the need for better strategies to address poor persistence and adherence.

A preliminary investigation of nutritional intake and supplement use in Australians with myalgic encephalomyelitis/chronic fatigue syndrome and the implications on health-related quality of life.

BackgroundMyalgic encephalomyelitis/chronic fatigue syndrome (ME/CFS) is a complex, multisystem illness without a currently recognized pharmacological treatment. Dietary supplementation and modification have been posited as potential management strategies; however, their efficacy is controversial.ObjectiveThis study aimed to assess the nutritional intake and supplement use of Australian ME/CFS patients and the perceived effect on health-related quality of life (HRQoL) for the first time in an Australian patient population.DesignBetween February 2019 and January 2020, ME/CFS patients across Australia volunteered in this cross-sectional study in response to online advertisements. Eligible respondents were invited to complete three online self-administered questionnaires investigating their supplement use, nutritional intake, and HRQoL. The study participants’ supplement use and nutritional intake were summarized and compared with the population data returned from the Australian Health Survey (2011–2012). Multiple linear regression analysis was also performed to determine the effect of participants’ supplement use and nutrient intake on HRQoL.ResultsTwenty-four eligible ME/CFS patients (54.2% meeting the International Consensus Criteria, 79.2% female, mean age = 43.4 ± 10.5 years) completed the online questionnaires. Supplement use was highly prevalent among the study sample (87.5%) and considerably more common when compared with population data (31.9%). Daily total fats and caffeine intakes were significantly higher among ME/CFS patients when compared with the Australian population (P = 0.009 and P = 0.033, respectively), whereas daily intakes of total carbohydrates and alcohol were significantly lower (both P < 0.001). No consistent trends between nutrition and supplement use with patients’ HRQoL could be identified.ConclusionsThe daily diet and supplement use of ME/CFS patients appear to vary considerably from those of the general Australian population. Although the role of nutritional intake and supplement use on ME/CFS patients’ HRQoL remains unclear, dietary changes and the use of supplements appear to be of value to ME/CFS patients.

Prevalence of inflammatory bowel disease in the Australian general practice population: A cross-sectional study.

The burden of inflammatory bowel disease (IBD) in Australia is increasing but national data about the current prevalence are limited. We aimed to estimate the prevalence of IBD (including Crohn’s disease, ulcerative colitis and unspecified IBD) as well as Crohn’s disease and ulcerative colitis separately in a general practice population in Australia. We also assessed risk factors associated with Crohn’s disease and ulcerative colitis. We conducted a cross-sectional study using data from MedicineInsight, a national database of general practice electronic health records, from 1 July 2017 to 30 June 2019. The prevalence of IBD was calculated and stratified by sociodemographic characteristics. Logistic regression analysis was conducted to assess risk factors associated with Crohn’s disease and ulcerative colitis. The study comprised 2,428,461 regular patients from 481 practices. The estimated crude prevalence of IBD was 653 per 100,000 patients; Crohn’s disease was 306 per 100,000 and ulcerative colitis was 334 per 100,000. Males were independently associated with a lower risk of Crohn’s disease (OR: 0.86; 95% CI: 0.81, 0.90) but a greater risk of ulcerative colitis (OR: 1.12; 95% CI: 1.06, 1.17) than females. Compared to non-smokers, patients who were current smokers were associated with a greater risk of Crohn’s disease (OR: 1.13; 95% CI: 1.04, 1.23) but a lower risk of ulcerative colitis (OR: 0.52; 95% CI: 0.47, 0.57). Other factors positively associated with both Crohn’s disease and ulcerative colitis were age (≥ 25 years), non-Indigenous status and socioeconomic advantage. Our findings provide a current estimate of the prevalence of IBD, Crohn’s disease and ulcerative colitis in a large national general practice population in Australia and an assessment of the factors associated with Crohn’s disease and ulcerative colitis. These data can assist in estimating the health burden and costs, and planning for health services.

Trends in the Utilization of Lipid-Lowering Medications in Australia: An Analysis of National Pharmacy Claims Data.

Lipid-lowering medications comprise standard of care in the prevention of cardiovascular disease. This study examined the trends in the utilization of statin and non-statin medications in the Australian general population between 2013 and 2019. Pharmacoepidemiological analyses were performed using pharmacy dispensing data from Australian Pharmaceutical Benefits Scheme. One-year prevalence and incidence of statin and non-statin prescribing patterns were reported, and relative variations in prescribing examined via Poisson regression modelling. The one-year prevalence of statins' prescriptions decreased between 2013-2019 by 5.5% (from 25.0%-19.5%). Females were less likely than males to be prescribed statins (rate ratio [RR]=0.90, 95% confidence interval [CI] 0.89-0.91). The one-year prevalence of ezetimibe alone, and in combination with statins, increased consistently from 2013-2019 from 1.5%-3.6% (P<0.01) and 0.1%-1.1% (P<0.01), respectively. The prevalence was higher among those aged 61-80 years (RR=1.20, 95%CI 1.10-1.21) and those aged older than 80 years (RR=1.34, 95%CI 1.22-1.47), when compared to people aged <60 years. The incidence of ezetimibe prescriptions was highest in people aged 61-80 years (RR=1.36, 95%CI 1.31-1.41) compared to those aged <60 years. The one-year prevalence of proprotein convertase subtilisin/kexin type 9 inhibitor prescriptions was highest among those aged 46-60 years (RR=1.24, 95%CI 0.97-4.97) compared to people aged <46 and >60 years. Females were less likely than males to be prescribed a proprotein convertase subtilisin/kexin type 9 inhibitor (RR=0.87, 95%CI 0.75-0.98). Statins remain the most prevalent lipid-lowering medication prescribed in Australia. The prescribing of non-statin medications remains low, but is increasing.

The Functional Assessment of Cancer Therapy Eight Dimension (FACT-8D), a Multi-Attribute Utility Instrument Derived From the Cancer-Specific FACT-General (FACT-G) Quality of Life Questionnaire: Development and Australian Value Set

ObjectivesTo develop a cancer-specific multi-attribute utility instrument derived from the Functional Assessment of Cancer Therapy - General (FACT-G) health-related quality of life (HRQL) questionnaire. MethodsWe derived a descriptive system based on a subset of the 27-item FACT-G. Item selection was informed by psychometric analyses of existing FACT-G data (n = 6912) and by patient input (n = 82). We then conducted an online valuation survey, with participants recruited via an Australian general population online panel. A discrete choice experiment (DCE) was used, with attributes being the HRQL dimensions of the descriptive system and survival duration, and 16 choice-pairs per participant. Utility decrements were estimated with conditional logit and mixed logit modeling. ResultsEight HRQL dimensions were included in the descriptive system: pain, fatigue, nausea, sleep, work, social support, sadness, and future health worry; each with 5 levels. Of 1737 panel members who accessed the valuation survey, 1644 (95%) completed 1 or more DCE choice-pairs and were included in analyses. Utility decrements were generally monotonic; within each dimension, poorer HRQL levels generally had larger utility decrements. The largest utility decrements were for the highest levels of pain (-0.40) and nausea (-0.28). The worst health state had a utility of -0.54, considerably worse than dead. ConclusionsA descriptive system and preference-based scoring approach were developed for the FACT-8D, a new cancer-specific multi-attribute utility instrument derived from the FACT-G. The Australian value set is the first of a series of country-specific value sets planned that can facilitate cost-utility analyses based on items from the FACT-G and related FACIT questionnaires containing FACT-G items.

Factors associated with the time to transition from suicidal ideation to suicide plans and attempts in the Australian general population.

Suicide plans and attempts rarely occur without prior suicidal ideation but are hard to predict. Early intervention efforts need to focus on subgroups of the population who are more likely to transition from ideation to suicidal plans and attempts. The current study utilised data from a large nationally representative sample to investigate the time taken to transition and the demographic and mental health correlates of transitioning to suicidal plans and attempts among those with suicidal ideation. Data were from 1237 Australians aged 16-85 years who reported suicidal thoughts at some point in their life. Discrete time survival analysis was used to retrospectively examine the time in years and correlates of transitioning from suicidal ideation to suicide plans and suicide attempt. The majority of those who transitioned to suicide plans or attempts typically did so within 2 years of first experiencing suicidal ideation. Several factors were independently associated with increased speed to transition, including alcohol use disorder, drug use disorder, major depressive episode, obsessive compulsive disorder, sexual minority status, and non-urban location. Older age, being male, older age of first ideation and greater family support were associated with a slower transition. The current study suggests that pre-existing mental or substance use disorders, particularly drug use disorder, as well as sexual minority status, sex and greater family support play an important role in the transition from suicidal ideation to plans or attempts. These results highlight the potential importance of suicide prevention programs that aim to improve social connectedness.

A Qualitative Analysis of Motivators to Participation in Suicide-Focused Research from a Community-Based Australian Sample.

Suicide prevention strategies internationally appear to be falling short of making a meaningful impact on global suicide deaths. Increasing the rates of general community participation in suicide research may improve knowledge generalisability as it relates to suicidal behaviour and leads to new suicide prevention approaches. This study aims to explore the motivations of a community-based sample to participate in suicide research. A subsample of the Australian general population took part in an online survey which is part of a multilevel suicide prevention trial. The survey concluded with an optional open-text question asking about peoples’ motivations for participating in the study; 532 participants left a response to this question. These responses were qualitatively analysed using Thematic Network Analysis. Motivations to participate in suicide research were represented by four global themes: altruism, solve systemic problems, lived experience, and personal benefit. Of these themes, three were focused on the benefit of others, while only the final theme articulated motivation to participate that was self-focused. The impact of suicide is felt throughout the wider community. This new understanding of the motivations of community-based samples to participate in suicide research should be used to increase participation rates and reach people who would not normally contribute their voice to suicide research.

Working from home, quality of life, and perceived productivity during the first 50-day COVID-19 mitigation measures in Austria: a cross-sectional study

ObjectivesTo explore changes in quality of life and perceived productivity, focusing on the effects of working from home during the first COVID-19 50-day mitigation period in Austria.MethodsWe conducted an Austrian-representative online survey (N = 1010) of self-reported life- and work-related changes during the first COVID-19 50-day mitigation period (March 16 through May 1 2020) compared to the situation before. We used multinominal logistic regression models to identify correlates of improved/decreased quality of life in the entire sample, and of improved/decreased productivity in a subsample of the working population (N = 686). We also calculated age- and multivariable-adjusted ORs and 95% CIs of an improved/decreased quality of life and an improved/decreased productivity by work from home status.ResultsDuring the COVID-19 mitigation period, quality of life improved in 17.5%, but decreased in 20.7% of the general Austrian population; perceived productivity at work increased in 12.7%, but decreased in 30.2% of the working population. Working from home during the mitigation period was associated with an increased quality of life (vs. none, partially: OR 2.07, 95% CI 1.09–3.91; all the time: 3.69, 1.86–7.29). In contrast, perceived productivity seemed to decrease when people worked from home (vs. none, partially: 1.42, 0.86–2.35; all the time: 1.48, 0.85–2.58). Working from home and related benefits were not equally distributed among gender, age, and educational attainment.ConclusionsA transition to more flexibility of workplace and working hours for employees could have important positive consequences for family and professional life, for stakeholders, for public health, and ultimately for the environment.

SARS-CoV-2 seroprevalence in healthcare workers in a tertiary healthcare network in Victoria, Australia.

BackgroundHealthcare workers (HCW) are exposed to an increased risk of COVID-19 through direct contact with patients and patient environments. We calculated the; seroprevalence of SARS-CoV-2 in HCW at Eastern Health, a tertiary healthcare network in Victoria, and assessed associations with demographics, work location and role.MethodsA cross-sectional cohort study of HCW at Eastern Health was conducted. Serum was analysed for the presence of antibodies to SARS-CoV-2, and all participants completed; an online survey collecting information on demographics, place of work, role, and exposures; to COVID-19. Seroprevalence was calculated as the proportion participants with SARS-CoV-2; antibodies out of all tested individuals.ResultsThe crude seroprevalence of SARS-CoV-2 antibodies in this study was 2.17% (16/736). Thirteen of the 16 (81.2%) positive cases had previously been diagnosed with COVID-19 by PCR: the seroprevalence in the group not previously diagnosed with COVID by PCR was 0.42% (3/720). Having direct contact with COVID-19 patients did not increase the likelihood of having positive serology. A prior history of symptoms consistent with COVID-19 was associated with a higher likelihood of having positive serology (OR 17.2, p = 0.006, 95%CI: 2.25–131.55).ConclusionOur calculated seroprevalence of 2.17% is higher than estimated in the general Australian population, but lower than that reported in HCW internationally. The; majority of those with positive serology in our study had previously been diagnosed with COVID-19 by PCR based testing. Seropositivity was not associated with interaction with COVID-19 positive patients, highlighting effective infection prevention and control practices within the workplace.
