Developing a policy simulator at the acute-aged care interface.

This paper describes the development of a computer simulation of the interactions between the acute and aged care systems in Australia, using system dynamics modeling enhanced by agent-based techniques. National and regional simulations will be developed, enabling the impact of a variety of policy scenarios to be forecast over the next 10 years. The paper includes a description of the relevant policy environment and some of the associated key policy issues.

Mental health literacy in rural Queensland: results of a community survey.

OBJECTIVES: The aim of this study was to assess the awareness of, and attitudes to, mental health issues in rural dwelling Queensland residents. A secondary objective was to provide baseline data of mental health literacy prior to the implementation of Australian Integrated Mental Health Initiative--a health promotion strategy aimed at improving the health outcomes of people with chronic or recurring mental disorders. METHOD: In 2004 a random sample of 2% (2132) of the estimated adult population in each of eight towns in rural Queensland was sent a postal survey and invited to participate in the project. A series of questions were asked based on a vignette describing a person suffering major depression. In addition, questions assessed respondents' awareness and perceptions of community mental health agencies. RESULTS: Approximately one-third (36%) of those surveyed completed and returned the questionnaire. While a higher proportion of respondents (81%) correctly identified and labelled the problem in the vignette as depression than previously reported in Australian community surveys, the majority of respondents (66%) underestimated the prevalence of mental health problems in the community. Furthermore, a substantial number of respondents (37%) were unaware of agencies in their community to assist people with mental health issues while a majority of respondents (57.6%) considered that the services offered by those agencies were poor. CONCLUSION: While mental health literacy in rural Queensland appears to be comparable to other Australian regions, several gaps in knowledge were identified. This is in spite of recent widespread coverage of depression in the media and thus, there is a continuing need for mental health education in rural Queensland.

Hormones down under: hormone therapy use after the Women's Health Initiative.

AIMS: The primary objective was to describe the usage pattern of hormone therapy (HT) in a sample of urban Australian women in 2001 and to assess the characteristics of users vs. non-users. The second objective was to determine whether there had been any change in usage since the publication of the results of the combined oestrogen plus progestagen arm of the Women's Health Initiative (WHI) in 2002. METHODS: A cohort of 374 postmenopausal women aged 50-80 years participated in this substudy of the LAW (Longitudinal Assessment of Ageing in Women) project: a 5-year multidisciplinary, observational study. Participants completed an annual medical assessment including details of the use of HT and the reasons for use, as well as demographic and psychosocial data. RESULTS: In December 2001, 30.8% of the participants were using HT, whereas 55.4% were ever users. The management of vasomotor symptoms and mood disturbance were the primary reasons for use. Of those who had been using HT in December 2001 (24.4%) women ceased using HT in the 3 months following publication of the WHI results. The percentage of women using HT in December 2003 (13.9%) was less than half of that of December 2001. CONCLUSION: The rate of HT use and the reasons for use, in 2001 in Brisbane was similar to that of other Australian regions. Usage of HT decreased since the publication of the WHI results in 2002 which may reflect changing attitudes by patients and practitioners regarding HT.

An investigation of organic factors in the neuropsychological functioning of patients with borderline personality disorder.

The hypothesis to be tested in this study was that the cognitive deficits that have been documented in patients with Borderline Personality Disorder (BPD) are largely the consequence of organic insult, either developmental or acquired. Using a cross-sectional design, 80 subjects (males and females) who met the criteria for BPD participated in the study. They completed a battery of neuropsychological tests and a comprehensive interview assessing organic status as well as measures of the potentially confounding factors of current levels of depression and anxiety. It was expected that BPD-patients with a probable history of organic insult would perform significantly worse than would BPD patients without such a history. Analyses of the results provided partial support for the hypothesis. Subjects with both BPD and a history of organic insult were significantly more impaired on several measures including measures of attention than were BPD only subjects. The results suggested that the impaired cognitive performance of persons diagnosed with BPD may, in part, be attributed to organic factors.

The influence of postmenopausal hormone replacement therapy on cognitive functioning: results from an observational study.

OBJECTIVES: The aim of this study was to evaluate the impact of hormone replacement therapy (HRT) upon memory deficit in a group of urban Australian women. PARTICIPANTS AND SETTING: A cohort of 493 women aged 40-80 years was tested as part of the Longitudinal Study of Ageing in Women (LAW study) at the Royal Brisbane and Women's Hospital, Brisbane, Australia. MAIN OUTCOME MEASURES: The current memory functioning of participants was evaluated using the Wechsler Memory Scale - version three (WMS-III) while pre-morbid cognitive functioning was estimated from scores on the National Adult Reading Test (NART). Memory deficit was estimated by comparing NART scores with the age-corrected scale scores of the WMS-III. RESULTS: Overall, NART scores correlated with WMS-III scores, consistent with the expected relationship between pre-morbid functioning and current functioning. For the sample as a whole, memory deficit was evident but mostly, age appropriate. There was considerable variation as to the extent of memory deficit within the sample. When memory functioning for women with a history of five or more years of combined oestrogen plus progestogen HRT or oestrogen replacement therapy (ERT) was compared with that of women who had never used HRT or ERT there was no evidence of any effect for either HRT or ERT on memory deficit. CONCLUSIONS: The use of HRT or ERT had neither a protective nor an adverse effect on memory deficit.
