Centre for Applied Statistics in Health

About CASiH

Based at the Australian Health Services Research Institute (AHSRI) is the Centre for Applied Statistics in Health (CASiH). Members of CASiH come from a variety of backgrounds. All have formal qualifications in statistics or an analyst role in the centre and all have previously worked in areas where they have had to analyse data, prepare reports to present their results and disseminate their findings in other ways.

The focus of all CASiH’s work is to find the story hidden in the data and to present these findings in ways that are clearly understood and easily applied to their health system context.

Members of CASiH have expertise in all areas of applied statistics, including classification development, time series, statistical modelling, regression analysis in its many guises, survey design and analysis and experimental design. They work across all other centres in AHSRI, applying their expertise to the quantitative elements of a wide variety of projects, from their design through to the dissemination of the results.

CASiH staff

Dr Conrad Kobel primarily contributes to the ongoing research and development of casemix systems in Australia, feeding into the national activity based funding program. Furthermore, he has provided statistical and technical expertise in a number of projects investigating and improving costing methodologies, funding model design and strategic management of health services.

Before joining AHSRI in 2013 he worked as a research fellow at Innsbruck Medical University in Innsbruck, Austria for almost five years. There, he was a key researcher in the EuroDRG project, which compared multiple aspects of several European Diagnosis-Related Group systems. Within the project, Conrad primarily contributed to the methodological framework of the empirical analyses. In addition, he supported clinical research with statistical analyses and taught applied statistics to medical students.

With his international experience, he strengthens and broadens the capacity of the quantitative analysis team at AHSRI. Conrad has international collaborations with Canada and Europe and is a faculty member of an annual short course that provides comprehensive skills on the design, implementation and evaluation of casemix-based funding models run by the Patient Casemix Systems International (PCSI). Conrad has studied mathematics and financial mathematics in Germany and Sweden and has completed the Doctoral Program in Social and Economic Sciences (main focus on health economics) at Innsbruck University in Austria.

Dr Luise Lago is a Senior Research Fellow working for CHRISP. She is currently researching Frequent Attenders to Emergency Departments and supporting research projects in the areas of Secondary Prevention of Atherosclerosis, Identification of Dementia, Suicide Prevention, Rehabilitation, Allied Health and adverse drug events.

Luise has more than 15 years of research experience in government and academia, including the areas of classifications development, hospital funding, longitudinal data analysis, biostatistics and epidemiology. Her PhD was on the use of mixed models for imputation of missing data in household surveys.

Dr Victoria Westley-Wise is a Clinical Epidemiologist working for CHRISP. As a member of the CHRISP team, she works closely with Illawarra clinicians, statisticians and other researchers to design and implement research using IHIP data and infrastructure. Victoria has 30 years’ experience in the health system, including 25 years in public/population health, service planning and evaluation, and epidemiology roles. She has undertaken epidemiological evaluations and research in a range of areas, using both descriptive and analytic study designs. 

Tara is a full-time member of AHSRI, joining in 2002 after working at the Australian Insitute of Health and Welfare. As the AROC Data Manager she is responsible for data management, benchmarking and reporting components of AROC. Tara brings extensive statistical and database management skills to AHSRI. She is mostly involved in AROC projects and some CHSD projects, ranging from rehabilitation specific patient experience surveys, to community health and community care surveys, to building databases to assist various evaluation projects. Tara has experience in linkage of de-identified data sets and has provided the statistical work for building a number of priority rating tools for the community care side of the Institute's work.

As the statistician for the electronic Persistent Pain Outcomes Collaboration (ePPOC), Sam supports the data management, benchmarking and reporting components of the program. He has more than 10-years of experience in the areas of data development, patient outcome measurement, casemix development and health service benchmarking. Sam received his BMath(Hons) from the University of Wollongong and is currently completing a Master of Biostatistics.

Sonia joined the AHSRI in 2007 after working at the Australian Institute of Health and Welfare. Sonia supports research projects requiring data management and statistical analysis and is primarily involved in the Palliative Care Outcomes Collaboration. She has extensive experience and skills in managing large complex datasets, SAS programming, reporting and evaluation. Sonia has tertiary qualifications in Mathematics and Applied Statistics. She also has a Masters by Research and a Graduate Certificate in Health Services Research and Development.

Megan Blanchard is a Research Fellow (Applied Statistics) who joined AHSRI in 2010 after working at the Australian Bureau of Statistics. Since joining AHSRI, Megan has been part of the core team working on the development of classifications such as the Australian Refined Diagnosis Related Group (AR-DRG) classification v7.0 and Australian National Subacute and Non-Acute Patient (AN-SNAP) classification v4.0. Megan also has experience in health outcome measurement – she was the statistician for the electronic Persistent Pain Outcomes Collaboration (ePPOC) for 7 years and is now responsible for the statistical components of the Palliative Care Outcomes Collaboration (PCOC). 

Alanna Connolly joined AHSRI in July 2013 after working at BlueScope Steel for a number of years. She has tertiary qualifications in Engineering and Applied Statistics. Alanna is currently working on PCOC. 

Dr Palacios-Derflingher commenced with CHRISP in April 2021. She has experience working as a Biostatistician in research, academic and consulting roles in interdisciplinary environments in health services research, in the Faculties of Kinesiology, Nursing and Medicine at the University of Calgary (Canada), focusing on Injury Prevention, Family Medicine and Nephrology. During this time she also taught statistical graduate courses to non-statisticians.

Her contributions have covered nearly all steps of research: informing and planning of design of studies, creation of methodological plans, supervising and performing (complex) statistical analyses and interpretation, and manuscript preparation. Her interests include the correct use of statistical techniques, overall research methodology, interpretation of results, and the analysis of longitudinal data and recurrent events.

Dr Mijan has a background in statistics, gerontology, and public health. He was recently awarded a PhD in clinical epidemiology and medical statistics from the University of Newcastle. Previously, he received an MSc in gerontology from the University of Southampton (United Kingdom) and graduated in statistics from the University of Rajshahi (Bangladesh). He has over 10 years’ experience in teaching statistical courses to undergraduate and graduate level students. His research interests includes modelling trajectories of health and aged care service use across later life, determinants of healthy ageing and health life expectancy, and health service outcomes and policy evaluation. He has expertise in applying advance statistical techniques to analyse complex longitudinal survey and linked health records. He has published 18 articles in top ranking, international peer-reviewed journals.
