Career Summary

Biography

Xenia Dolja-Gore is an NHMRC Centre of Research Excellence in Women’s Health in the 21st Century (CREW21) research fellow at the Research Centre for Gender, Health and Ageing. Xenia’s work primarily involves the development and implementation of analytical techniques to explore and analyses linked longitudinal health data.

As senior bio-statistician for the group, Xenia’s role is to provide advice on the statistical direction for the analysis of linked survey, National Death Index, hospital and Medicare data.  In addition, Xenia gives statistical support and advice to junior members in the project team and contributes to the writing of research grant proposals.  As an academic statistician, Xenia is involved in contributing to government reports, writing academic papers for presentation at conferences and for submission to journals for publication, as well as contributing to the design and conduct of research projects. 

Xenia has been involved with statistical research in health related areas for over 20 years. During this time she has specialised in areas such as the development of appropriate patient care indicators and quality assurance in the health care sector and has now focused on mental health services utilisation and the social determinants that drive those in need to use mental health services.  Currently planned research for CREW21 includes an examination of factors associated with healthy ageing in older women.

Xenia has a background in Mathematics and is currently completing her PhD where she has applied the pseudo-randomised technique of propensity score analysis to the Australian Longitudinal Study on Women’s Health data linked to the Medicare Medical Benefits Schedule (MBS) and Pharmaceutical Benefits Scheme (PBS) data enabling an examination of the treatment effects of mental health service use for women with poor mental health. 

Xenia has successfully applied for over $200,000 in external research grants, co-authored four major reports submitted to the Department of Health and Ageing, has published eleven peer-reviewed journal articles and presented at 25 national and international conferences and invited to review articles for two well-known journals.

Teaching Expertise
Xenia has taught statistics to both under-graduate and post-graduate students, internal/external students. Under-graduate teaching included lesson preparation, student consultation time, marking of assignments and face to face teaching. Post-graduate courses were offered as distance learning courses and delivered via the web platform Blackboard. As several students are local, tutorial classes were also offered in a face-to-face environment.   

Xenia has also co-supervised two post-graduate masters students under the Masters of Public Health program.

Collaborations

Currently a participant of MURA users group, Health data linkage Interest Group and the SAX Institute Users groups.

© 2015 Elsevier Ireland Ltd.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.

© 2016 John Wiley & Sons, Ltd.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.

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.
