Summary
Economic evaluation is used increasingly by health care decision makers to decide which health care programs provide the best value for money, in terms of improving health and quality of life outcomes for the population. It is used by the Australian government in deciding which medical services and pharmaceuticals should be funded.

It is used by the Australian government in deciding which medical services and pharmaceuticals should be funded. This requires measurement of quality of life in a way that allows comparison across treatments, and a means of quantifying community preferences for different health states (that is, how we value health outcomes). Health outcomes are often valued using the quality adjusted life year (QALY) which combines length and quality of life in a single measure. To compare across diseases and treatments, quality of life must be measured in the same way. This can be done by using a standard set of questions that cover the different aspects of quality of life (eg pain, mobility, emotional state). In this way, a single survey instrument can be used for any disease or outcome of treatment. We can also use the same instrument to ask members of the public to provide information about their preferences for different health states (that is how they value health outcomes). However, obtaining this information from respondents is complex, and there is debate about which are the best instruments, and the best methods to value health outcomes. In this research, we propose a new approach to valuing health states, which is easier to administer and which allows for more detailed and rigorous analysis of the responses people give, to provide better models of how the different aspects of quality of life are combined in valuing health outcomes. We will compare the new method with the main existing methods. We will compare these methods for two standard quality of life instruments that are widely used in health care research. The research will also provide valuations of health states from the Australian population that can then be used in economic evaluation.Read moreRead less

It provides an exciting opportunity to bring together scholars across economics at the forefront of the discipline internationally, who are researchers with extensive experience in the practical application of research results in shaping policy directions. The approach will fill the repeatedly identified gap in policy relevant health services research at the system level in Australia. The immediate outcomes of the research program will be information on specific health policy issues, in terms of the drivers of cost and utilization, access and equity.Read moreRead less
Measuring Patient Preferences For Treatment Of Colorectal Cancer Using Discrete Choice Modelling

Summary
Around the world, governments, medical professional bodies, individual clinicians and patients are trying to make decisions in health care more rationally.

More of these decisions are 'informed' by evidence-based medicine, which depends on a systematic review of all relevant evidence of acceptable scientific rigour. This kind of systematic review has been conducted for the management of colorectal cancer. Patients making choices about possible treatment for colorectal cancer will then have the best 'evidence-based' information to hand. But not enough is known about what aspects of the treatment options matter most to patients. Choosing between different treatment options involves weighing up or trading-off different factors associated with each therapy. Depending on the clinical stage of their cancer, patients may have to choose between the type and size of surgical operation, whether or not to have chemotherapy and-or radiotherapy, the side effects of treatment, the chance of a recurrence of the disease and an early death as well as their quality of life. This research project will ask patients who have already been treated for their colorectal cancer what kind of tradeoffs they make between factors such as disease-free survival, toxicity of treatment and longer term quality of life. This will be done using hypothetical clinical scenarios comparing one type of treatment to another. In this way, the hypothetical choices will be informed by the patient's experience with treatment without asking them to reflect or dwell directly on their own treatment choices. The answers to the hypothetical choice questions can be used to assess what factors in treatment are most important to patients and by how much. This information can then be used by clinicians when presenting evidence-based information on treatment for patients newly diagnosed colorectal cancer.Read moreRead less
Neuronal Substrate Of Choice In The Rat Whisker System

Summary
Humans and other animals can optimise their goal-directed behaviour by linking stimuli or actions to consequent positive and negative rewards. How does an animal generate such associations, and make decisions in the natural environment where the associations are often uncertain, at times contradictory, and continuously changing? This project uses rat whisker system as an animal model to identify the neuronal basis of perceptual decision making and the role of context.
New Approaches To Describing And Valuing Quality Of Life

Summary
The ability of healthcare to improve quality of life is a major factor in determining public subsidy. This fellowship first explores patterns in Australian quality of life. This will identify groups with poor quality of life, and the remedying impact achieved under various interventions. It will then consider how people place value on aspects of quality of life. The two strands will allow linkage between important areas of quality of life and the policy impact of health interventions.
