The Australian Burden of Disease project quantifies the relative burden associated with each disease. New estimates are to be released this year will outline the magnitude of burden associated with dementia now and estimate that for the year 2023. Although the projections use the best data available, three improvements to the methodology would improve the accuracy of the dementia burden estimates. First, the dementia calculations currently use a “disability weight” metric derived from a Dutch study. This is problematic in that the weights do not reflect an Australian experience of dementia, nor do they reflect the preferences of people closely affected by the disease (e.g. carers). Second, the dementia estimates do not include cases of mild cognitive impairment (considered a precursor state of dementia). Hence the dementia estimates may not estimate the full impact of dementia in Australia. Finally, there is no evidence that the method used by the Burden of Disease study to account for the impact of disease comorbidity adequately deals with the comorbidity associated with dementia. Consequently, there is need to develop a new and comprehensive set of disability weights for dementia that are Australian-based, include all stages of dementia severity and account for comorbidity. The proposed project aims to develop a new set of empirically derived Australian-based disability weights for dementia. The project will entail three studies. The first study will generate empirically based case vignettes that describe a range of dementia case scenarios. These descriptions will then be used in rating exercises (Study 2) to develop new disability weights. The second study involves Australian health practitioners, carers and lay persons reading case vignettes and completing health valuation rating exercises to generate new disability weights for dementia. The third study uses the new disability weights to re-calculate the burden of disease estimates for dementia. The new estimates will be compared to those reported by the 2007 Australian Burden of Disease project. In knowing the accuracy of the estimates, policy makers can use the burden data for dementia with confidence when engaging in service planning for the future.Read moreRead less
Statistical Methods And Algorithms For Analysis Of High-throughput Genetics And Genomics Platforms

Summary
Through rapid advances in high-throughput -omics technologies, the number of phenotypes and the number of genotypes in gene mapping studies are or will be orders of magnitudes larger than in previous studies. Current algorithms and analysis methods have not kept up with the speed of data collection, nor has the training of qualified researchers. We will develop quantitative trait loci (fine) mapping analysis methods and bioinformatics algorithms and train (post)graduates in these research areas.
Person-centred Environment And Care For Residents With Dementia: A Cost-effective Way Of Improving Quality Of Life And Q

Summary
Improving the quality of life (QOL) and quality of care for persons with dementia are important areas of Australian health research. A growing body of evidence shows that QOL in dementia can be improved by relatively simple and inexpensive modifications to nursing care practices and the physical environment. Most studies in these areas are observational, few have utilized a randomized control group design, and none has included economic evaluation. This study will address these deficiencies.

A growing body of evidence shows that QOL in dementia can be improved by relatively simple and inexpensive modifications to nursing care practices and the physical environment. Most studies in these areas are observational, few have utilized a randomized control group design, and none has included economic evaluation. This study will address these deficiencies. This is the first time that a randomized controlled trial of Person-Centred Care (PCC) and Person-Centred Environment Design (PCD) will be undertaken. The study will be conducted in 40 residential aged care services in New South Wales, to determine the efficacy and cost effectiveness of implementing PCC and PCD separately, and in combination, in improving resident quality of life and quality of care.Read moreRead less
Production Of Nasal Filters: Enhanced Prophylactic Protection From Aerosol Exposure

Summary
Influenza is a highly contagious disease that is transmitted via infective secretions containing the virus. An infected person produces tiny droplets of these secretions when coughing, sneezing, and talking, and the droplets are disseminated into the air where they are subsequently inhaled by others. A common way of preventing such transmission is to wear a mask to prevent droplet inhalation. While such masks may greatly reduce exposure, they do not eliminate it, as some viruses can pass around ....Influenza is a highly contagious disease that is transmitted via infective secretions containing the virus. An infected person produces tiny droplets of these secretions when coughing, sneezing, and talking, and the droplets are disseminated into the air where they are subsequently inhaled by others. A common way of preventing such transmission is to wear a mask to prevent droplet inhalation. While such masks may greatly reduce exposure, they do not eliminate it, as some viruses can pass around the edges of masks, particularly if it fits poorly, and also a small percentage can pass through the filter material. While influenza is usually not a major health problem in the general community, the emergence of a more hazardous strain will place an additional burden on health care and other facilities, and requires the development and optimization of measures to minimize virus spread and protect those who are exposed. The aim of this project is to build small filters that can be worn in the nose to provide additional filtration of inhaled air. These filters would be worn in combination with a mask in high exposure circumstances, such as by health care workers when treating infected patients or could be used when a mask was not normally worn to provide effective and discreet protection, such as in crowded public places. Developing such filters builds on our experience of making small samplers worn in the nose to measure allergen exposure. This experience is combined with advanced filter materials developed by leading US researchers that permit the efficient filtration of particles as small as viruses. This project will be conducted in collaboration with a leading Australian design group, and we will design and evaluate such filters for their ability to capture virus and thus protect the wearer. The filters should provide an intuitive, effective and inexpensive method to be used in combination with other hygiene measures to increase personal protection from acquiring highly transmissible respiratory diseases, particularly influenza. We expect to have prototypes of the filters available in 6 months so that production can commence.Read moreRead less
