Background: Comorbidity can complicate cardiovascular diseases (CVDs), increasing the risk of adverse events including hospitalisation and death. This study aimed to assess the Charlson Comorbidity Index (CCI) as a predictor of repeated hospital admission and mortality in older CVD patients. Methods: This study linked data from the Australian longitudinal study on women¿s health (ALSWH) with hospital and National Death Index datasets to identify dates for hospital admission, discharge, and death for women born 1921¿26. CCI was calculated using the International Statistical Classification of Diseases, Australia Modification (ICD-10-AM) diagnostic codes. Results: Women with a higher CCI on index admission had increased risk of repeated hospital admission (AHR = 1.29, 95% CI 1.06, 1.58) and mortality (AHR = 3.05, 95% CI 2.15, 4.31). Older age and hypertension were also significantly associated with a higher risk of repeated hospital admission and mortality. Living in a remote area was associated with a higher risk of mortality. Conclusions: The Charlson Comorbidity Index predicts repeated hospital admission and mortality incidences among older women with CVD. Improving management of comorbidities for older CVD patients should be considered as part of a strategy to mitigate subsequent repeated hospitalisation and delay mortality.

Introduction: The number of older drivers is quickly rising as the world's population is ageing. Driving was found to be essential in improving older people's quality of life. However, in assessing factors associated with driving in old age, previous studies have focused on medical conditions and sociodemographic factors, such as age and sex. Little is known about the effect of environment and social roles in determining driving in old age. Objective: This study aimed to identify the predictors of driving among women as they age from 76 to 81 to 85¿90 years based on the World Health Organization's (WHO) Healthy Ageing framework. Method: The study analysed longitudinal data from the 1921¿26 cohort of the Australian Longitudinal Study on Women's Health (ALSWH), nine years of follow up from survey waves three (aged 76¿81 years) to six (aged 85¿90 years). The study examined factors associated with driving based on the WHO's healthy ageing approach. Generalised estimating equation (GEE) models were used to identify predictors of driving over time. Result: At baseline (ages 76¿81 years), 55.7% of women were driving themselves, and this was their main means of transport. Over time, the odds of driving decreased as the women aged. In multivariable analyses, personal factors including education, providing care, grandparenting, and volunteering had positive associations with driving. In addition, the environmental factors of living in remote, outer regional and inner regional Australia, living in the states of Victoria and Western Australia, and living alone were also positively associated with driving. In contrast, medical conditions like diabetes, stroke, visual impairment, and need for assistance with daily tasks had negative associations with driving. Conclusion: Age alone does not determine driving. Therefore, the context of personal, social, and environmental factors should also be considered and aligned with the healthy ageing goals when developing driving policy for older people.

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.

Objectives: Explore characteristics of hospital use for adults aged 85 and over in their last year of life and examine factors associated with cumulative overnight length of stay (LOS). Data source/study setting: NSW 45 and Up Study linked with hospital data. Study design: Longitudinal cohort study. Methods: Quantile regression models were performed for men and women (N = 3145)to examine heterogeneity in predictors of overnight hospital admissions. Coefficients were estimated at the 25th, 50th, 75th and 90th percentiles of the LOS distribution. Principal findings: 86% had at least one hospitalisation in their last year of life, with 60% dying in hospital. For men, first admission for organ failure was associated with a 26 day increase at the 90th LOS percentile, and a 0.22 day increase at the 10th percentile compared to men with cancer. Women admitted with influenza had decreased LOS of 20.5 days at the 75th percentile and 6 to 8 fewer days at the lower percentiles compared to those women with cancer. Conclusions: Poor health behaviours were a major driver of highest LOS among older men, pointing to opportunities to achieve health care savings through prevention. For older women, influenza was associated with shorter LOS, which could be an indicator of the high and rapid mortality rates at older ages, and may be easily prevented. Other factors associated with LOS among women, included where they lived before they were admitted, and discharge destination.

Objective: To assess which older Australian women had Medicare subsidized health assessments between 1999 and 2013. Methods: This study used prospective, longitudinal survey data from the 1921 to 1926 birth cohort of Australian Longitudinal Study on Women¿s Health (ALSWH) linked with Medicare Australia data on health services use. Over 11,000 Australian women were included in the study. Latent class analysis was used to identify assessment patterns over time, accounting for death, and based on three categories (¿no assessment¿; ¿assessment; ¿deceased¿) for each year between 1999 and 2013. Further analysis explored the impact of health and sociodemographic characteristics on class membership. Results: Of the women included in the latent class analysis, 37% never had any assessment and the remainder had had at least one assessment. After a steady uptake from 1999 to 2003, there was decline in uptake from 2003 onwards. A six-class model with sufficient homogeneity and reliable estimation was selected to represent assessment patterns and mortality risk, labelled as: ¿high mortality¿ rate with little chance for assessment (12.4%), ¿intermediate mortality, low assessment¿ (14.1%), ¿later mortality/low assessment¿ (13.1%), ¿later mortality, high assessment¿ (7.0%), ¿low mortality, low assessment¿ (31.8%), ¿low mortality, high assessment¿ (21.6%). Older women with certain conditions (such as diabetes, depression, heart disease) were more likely to be in the low assessment groups, and women with difficulty managing on income were more likely to be in low assessment groups. Conclusion: Distinct assessment and mortality patterns were seen, with many women not having assessment, in particular those who had certain health conditions, were taking 3+ medications, had difficulty in managing on income, needed help or were in respite care, and had caring responsibilities. The findings point to a need to promote these assessments among older women, and to reduce financial barriers, even within the context of a heavily subsidized health care system.

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.

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.

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.

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 Women's 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.

This study examines differences in uptake of the Medicare items rolled out in 2006 under the 'Better Access Scheme' (BAS) between rural and non-rural Australian women. It compares differences in women's uptake of the BAS services by area of residence (ARIA+) across time using the Australian Longitudinal Study of Women's Health (ALSWH) survey data linked to Medicare data. Women aged 28-33 years at the time the BAS was introduced that responded to the self-reported question on depression/anxiety and consented to linkage of their survey data with Medicare data (n=4316). Participants were grouped by ARIA+according to BAS use, diagnoses of anxiety/depression but no BAS use and other eligible women. Across all areas, women born 1973-1978 with a self-reported diagnosis of depression/anxiety or having treatment under the BAS had a significantly lower mean mental health score compared to other women. Significantly more women living in non-rural areas had used at least one service provided under the BAS initiative compared to women in outer regional, inner regional or remotes areas (21% versus 18% versus 13% versus 7%, respectively), and across all areas, 12% of women reported having a diagnosis of depression/anxiety but not been treated under the BAS. While there is a gradual uptake of the new BAS services, a large percentage of women who have a diagnosis of depression/anxiety have not been treated under the BAS. The data suggest that women in urban areas have been better able to take up the services compared to non-urban women. © 2014 National Rural Health Alliance Inc.
