Objectives To determine the impact of intimate partner violence on women’s mental and physical health over a 16 year period and across three generations. Participants Participants were from the Australian Longitudinal study on Women’s Health, a broadly representative national sample of women comprised of three birth cohorts 1973–78, 1946–51 and 1921–26 who were randomly selected from the Australian Medicare (i.e. national health insurer) database in 1996 to participate in the longitudinal health and wellbeing survey. Since baseline, six waves of survey data have been collected. Women from each cohort who had returned all six surveys and had a baseline measure (Survey 1) for intimate partner violence were eligible for the current study. Main outcome measures The main outcome of interest was women’s physical and mental health, measured using the Medical Outcome Study Short-Form (SF-36). The experience of intimate partner violence was measured using the survey item ‘Have you ever been in a violent relationship with a partner/spouse?’ Sociodemographic information was also collected. Results For all cohorts, women who had lived with intimate partner violence were more likely to report poorer mental health, physical function and general health, and higher levels of bodily pain. Some generational differences existed. Younger women showed a reduction in health associated with the onset of intimate partner violence, which was not apparent for women in the older two groups. In addition, the physical health differences between women born 1921–26 who had and had not experienced intimate partner violence tapered off overtime, whereas these differences remained constant for women born 1973–78 and 1946–51. Conclusions Despite generational differences, intimate partner violence adversely impacted on mental and physical health over the 16 year study period and across generations.

Diabetes is a costly chronic disease that is associated with many complications and premature mortality. The cost of diabetes care has been predicted to rise dramatically over the next decade in Australia unless measures are taken to reduce complications and prevent or delay onset. New drugs are being introduced over time that may carry a higher cost for patients than those they supplant, for potentially marginal gains in health. An increase in medication costs for people on a fixed income may be a barrier to optimal care for chronic conditions such as diabetes. The Australian Longitudinal Study on Women’s Health (ALSWH) provides an opportunity to describe the medication costs for women with and without diabetes. Longitudinal selfreported survey data collected since 1996 from a random sample of more than 40,000 women about doctor-diagnosed medical conditions, linked with Medicare and Pharmaceutical Benefits Scheme (PBS) claims data, were used to classify women as having diabetes and to calculate medication co-payment costs. Almost 7,000 women in the ALSWH older cohort completed their fourth survey for the study in 2005 when they were aged 79-84 years. The prevalence of diabetes among women in this older cohort was 9% in 1996 when they were aged 70-75 years, rising to 15% of those remaining in the cohort by 2005. Large projected increases in costs in the areas of health, age pensions and aged care resulted in the Government putting in place a range of measures in 2004 to better control government spending,

After a period of steady decline, out-of-pocket (OOP) costs for general practitioner (GP) consultations in Australia began increasing in the mid-1990s. Following the rising community concerns about the increasing costs, the Australian Government introduced the Strengthening Medicare reforms in 2004 and 2005, which included a targeted incentive for GPs to charge zero OOP costs for consultations provided to children and concession cardholders (older adults and the poor), as well as an increase in the reimbursement for all GP visits. This paper examines the impact of those reforms using longitudinal survey and administrative data from a large national sample of women. The findings suggest that the reforms were effective in reducing OOP costs by an average of

A0.40 per visit. Decreases in OOP costs, however, were not evenly distributed. Those with higher pre-reform OOP costs had the biggest reductions in OOP costs, as did those with concession cards. However, results also reveal increases in OOP costs for most people without a concession card. The analysis suggests that there has been considerable heterogeneity in GP responses to the reforms, which has led to substantial changes in the fees charged by doctors and, as a result, the OOP costs incurred by different population groups.

BackgroundWhen a medicine such as rofecoxib (Vioxx) is withdrawn, or a whole class of medicines discredited such as the selective COX-2 inhibitors (COX-2s), follow-up of impacts at consumer level can be difficult and costly. The Australian Longitudinal Study on Womens Health provides a rare opportunity to examine individual consumer medicine use following a major discrediting event, the withdrawal of rofecoxib and issuing of safety warnings on the COX-2 class of medicines. The overall objective of this paper was to examine the impact of this discrediting event on dispensing of the COX-2 class of medicines, by describing medicine switching behaviours of older Australian women using rofecoxib in September 2004; the uptake of other COX-2s; and the characteristics of women who continued using a COX-2.MethodsParticipants were concessional beneficiary status women from the Older cohort (born 1921-26) of the Australian Longitudinal Study on Womens Health who consented to linkage to Pharmaceutical Benefits Scheme data, with at least one rofecoxib prescription dispensed in the 12 months before rofecoxib withdrawal. A prescription was defined as one dispensing occasion. Women were grouped by rofecoxib pattern of use: continuous (nine or more prescriptions dispensed in the 12 months prior to rofecoxib withdrawal) or non-continuous (eight or less prescriptions dispensed in the 12 months prior to rofecoxib withdrawal) users. Incidence rate per 100,000 person days and incidence risk ratio described uptake of alternate medicines, following rofecoxib withdrawal. Kaplan-Meier curves described differences in uptake patterns by medicine and pattern of rofecoxib use. Patterns of use of COX-2s in the next 100 days after first COX-2 uptake were described.ResultsMedicine switches and pattern of medicines uptake differed significantly depending upon whether a woman was a continuous or non-continuous rofecoxib user prior to rofecoxib discrediting. Continuous rofecoxib users overwhelmingly switched to another COX-2 and remained continuing COX-2 users for at least 100 days post-switch.ConclusionsThe typical switching behaviour of this group of women suggests that the issues leading to the discrediting of rofecoxib were not seen as a COX-2 class effect by prescribers to this high use group of consumers.

Background: By 2050, adults aged 80 years and over will represent around 20% of the global population. Little is known about how adults surviving into very old age use hospital services over time. Objective: The objective of the study was to examine patterns of hospital usage over a 10-year period for women who were aged 84 to 89 in 2010 and examine factors associated with increased use. Methods: Survey data from 1936 women from the 1921 to 1926 cohort of the Australian Longitudinal Study on Women’s Health were matched with the state-based Admitted Patients Data Collection. Hospital use profiles were determined using repeated measures latent class analysis. Results: Four latent class trajectories were identified. One-quarter of the sample were at low risk of hospitalization, while 20.6% demonstrated increased risk of hospitalization and a further 38.1% had moderate hospitalization risk over time. Only 16.8% of the sample was classified as having high hospitalization risk. Correlates of hospital use for very old women differed according to hospital use class and were contingent on the timing of exposure (ie, short-term or long-term). Conclusions: Despite the perception that older adults place a significant burden on health care systems, the majority of women demonstrated relatively low hospital use over an extended period, even in the presence of chronic health conditions. High hospitalization risk was found to be concentrated among a small minority of these long-term survivors. The findings suggest the importance of service planning and treatment regimes that take account of the diverse trajectories of hospital use into and through advanced old age.

In 1999, the Australian Federal Government introduced Medicare items for Health Assessments for people aged 75 years and older (75+ health assessments). This research examined uptake of these assessments and identified predictors of use by women from the Australian Longitudinal Study on Womens Health (ALSWH). Assessments were identified for each year from 1999 to 2013 using linked Medicare data. Time to first assessment was examined, as well as social and health factors associated with having an assessment. From 1999 to 2013, 61.8% of women had at least one assessment. Almost one-third had an assessment within 2 years of their introduction, 25% of women died before having an assessment and 13% survived but did not have an assessment. Factors associated with assessment included being widowed, private health insurance, marital status, education, having arthritis and urinary incontinence, and less difficulty managing on income. Many women never received an assessment, and many only received one. Promotion of the 75+ health assessments is necessary among older women to increase uptake.

ABSTRACT The current study aims to present the prevalence of adverse childhood experiences and examine the healthcare costs associated with primary, allied, and specialist healthcare services. The Australian Longitudinal Study on Women’s Health is a general health survey of four nationally representative age cohorts. The current study uses 20 years of survey and administrative data (1996–2015) from the cohort born 1973–1978. Overall, 41% of women indicated at least one category of childhood adversity. The most commonly reported type of childhood adversity was having a household member with a mental illness (16%), with the most commonly reported ACES category being psychological abuse (17%). Women who had experienced adversity in childhood had higher healthcare costs than women who had not experienced adversity. The healthcare costs associated with experiences of adversity in childhood fully justify a comprehensive policy and practice review.

This study examined factors associated with use of government subsidised mental health services by 229,628 men and women from the Sax Institute’s 45 and Up Study. Logistical regression models assessed use of mental health services by gender and according to level of psychological distress. Approximately equal proportion of men and women had high psychological distress scores (approximately 7%) but only 7% of these men and 11% of these women used services. Use was associated with predisposing (younger age and higher education), enabling (private health insurance) and need factors (higher psychological distress scores). Associations were similar for men and women except urban area of residence, separated/divorced marital status, and smoking were associated with service use for women but not men. Results suggest some inequity in the use of services by those with higher levels of need and further efforts may be required to reach people with higher need but lower service use.

There are increasing concerns regarding high hospital use among older adults and the capacity to manage the economic impact of the ageing population trend on healthcare systems. First hospitalisation in old age may act as a catalyst for ongoing intensification of health problems and acute care use. This study examined factors associated with first incident hospitalisation in women aged over 70, accounting for the health inequalities associated with geographic location. Survey data from 3780 women from the 1921 to 1926 cohort of the Australian Longitudinal Study on Womens Health were matched with the Admitted Patients Data Collection and National Death Index. Days to first event (hospitalisation or death) were modelled using competing risks methods. A total of 3065 (80.3%) women had at least one hospital admission. More than half of the top 15 reasons for first hospitalisation were related to cardiovascular disease, with atrial fibrillation the most common. Proportional subdistribution hazards models showed that first hospital admission was driven by enabling and need factors including asthma/bronchitis diagnosis (HR=1.16; p=0.047), private health insurance (HR=1.16; p=0.004) more than two prescribed medications in previous month (HR=1.31; p=0.001), more than four general practitioner visits in previous year (HR=1.50; p=0.034), lower physical functioning (HR=0.99; p<0.001) and living in an inner regional area (HR=1.17; p=0.003). First overnight hospitalisation was primarily related with potentially preventable and treatable chronic diseases. Primary and secondary strategies aimed at chronic disease generally, and better chronic disease management particularly for cardiovascular and respiratory diseases, may play a vital role in disease prevention or delay in readmissions among this population.
