Funding Amount
$85,827.00
Summary
Diabetes imposes a significant health and economic burden on Australia. This burden is set to increase as the population becomes older and risk factors for diabetes, such as obesity, become more common. The main aims of the proposed project are: 1. To develop computer-based models that will predict future patterns of diabetes and its complications in Australia. 2. To use these models to determine effective and cost-effective ways to reduce the future burden of diabetes in Australia.
Methamphetamine Clandestine Laboratories: An Analysis Of The Geo-spatial Dynamics Between Ecological Factors, Pharmacists, Pseudo-runners And Related Health Harms.

Summary
Methamphetamine (MA) manufacture in clandestine laboratories (clan labs) presents serious health and environmental risks beyond the impact on MA users. My fellowship seeks to better understand the interplay between the geography and population features of clan lab locations, the role of pharmacists and pseudo-runners in MA manufacture and MA-related harm. This evidence provides critical information for policy and program development aimed at reducing the MA manufacture and MA-related harm.
Identifying And Implementing Standardised Outcomes In Kidney Transplantation

Funding Amount
$274,076.00
Summary
The inconsistencies and lack of patient involvement in outcome selection for research can undermine shared decision-making and patient-centred care. Over three years, this global project will bring together patients,family members, healthcare providers, policy makers and industry to identify core outcomes in kidney transplantation. Implementation of the core outcome set will ensure that outcomes report in research are relevant, meaningful and important to patients with a kidney transplant.
The Who, Why, What, Where And When Of Primary Youth Mental Health Care: The 5W Research Program

Funding Amount
$857,288.00
Summary
headspace has been an international pioneer for primary mental health care for young people. However, we need to better understand how to match the range of services headspace provides to the diverse needs of its clients. In the 5W research program, we will use a range of big data techniques, machine learning, data linkage, discrete choice experiments and economic modelling to develop an acceptable, equitable and efficient stepped care model for headspace.

Summary
My research has 4 primary objectives, representing major gaps in current knowledge: 1. improve knowledge of recovery and determinants of post-concussive symptoms 2. establish the impact of child brain insult on socio-emotional function and identify contributing factors 3. develop an iPad based tool for socio-emotional function 4. evaluate and disseminate e-heath treatments for child brain insult
Combined Randomised And Observational Study Of Type B Ankle Fracture Treatment
Funder
National Health and Medical Research Council
Funding Amount
$117,331.00
Summary
Ankle fractures are frequently seen in emergency departments, and isolated AO type B fibula fractures are the most common type of ankle fracture. Current treatment is equally divided between surgical, and non-surgical, as per surgeon preference. When managed surgically, these fractures consume considerable healthcare resources and expose patients to risks. This study will determine if surgery improves outcomes for patients with type B ankle fractures when compared with non-surgical management.
Diagnostics For Mixture Regression Models: Applications To Public Health

Summary
In many public health studies, finite mixture regression models are often used to analyse data arising from heterogeneous populations. It is important to assess the stability of parameter estimates and the validity of statistical inferences when the underlying assumptions appear to be violated, but appropriate diagnostics are lacking in the literature.

It is important to assess the stability of parameter estimates and the validity of statistical inferences when the underlying assumptions appear to be violated, but appropriate diagnostics are lacking in the literature. This research aims to develop effective diagnostic methods for assessing the adequacy of mixture regression models and the sensitivity of accompanying test statistics. The methodology developed will enable health care professionals to focus on substantive issues and to draw accurate and valid conclusions inferred from correlated and over-dispersed outcomes. In the presence of anomalous observations, the influence diagnostics can provide insights into the source of heterogeneity and the apparent over-dispersion, while accommodating the inherent correlation due to the longitudinal study design or nested data structure. Significance of the research lies in its scientific novelty and the breadth of its practical applications. The benefits to public health will accrue both nationally and internationally. For the empirical studies that motivated and are linked to this research, evaluation of health outcomes has significant implications in the prevention and control of recurrent urinary tract infections, hospital strategic planning, and post-stroke care and rehabilitation management. Moreover, appropriate assessment of a physical activity intervention for older adults is pertinent to falls prevention and reduction of musculoskeletal disorders among sedentary seniors.Read moreRead less

Traditionally, the application of mixture models is mainly concerned with finite normal mixtures. Recent computational advances and methodological developments have enhanced the extension of the method to non-normal finite mixtures, such as the modelling of discrete responses in finite mixture of generalized linear models and overlapping phases of failure time data in the context of survival analysis. However, due to the hierarchical study design or the data collection procedure, the inherent correlation structure and-or clustering effects present may contribute to extra variations and violation of the independence assumption, resulting in spurious associations and misleading inferences based on the finite mixture model. This project aims to present a unified approach to accommodate both heterogeneity and dependency of observations, by incorporating random effects into finite mixture regression models. The new methodology will provide an integrated framework to analyze heterogeneous and correlated health outcomes. Three empirical studies are considered, namely, evaluation of an occupational injury reduction intervention, length of hospital stay modeling, and analysis of survival times of patients after cardiac surgery. The long term benefits to bioscience are accurate and valid conclusions inferred from medical and health studies, as well as the correct identification of high-risk subgroups. For the three application areas of this project, the improved analyses will specifically enable the evaluation of a participatory ergonomics intervention, the assessment of hospital efficiency and factors influencing length of hospitalization, and the determination of effectiveness of treatments prescribed pre- and post- operation, respectively.Read moreRead less
