Ambulance Demand: Random Events Or Predictable Patterns

Funding Amount

Summary
Over the past 20 years there has been an increase in demand for emergency ambulance services across the developed world, placing significant strain on ambulance resources. However, it is not known if demand is constant across different times of day, days of the week or months of the year. This PhD will examine temporal patterns in ambulance demand using four years of data derived from paramedic assessment. Understanding these patterns will provide evidence to inform ambulance practice.
Implications Of The Increasing Duration Of Life Spent With Obesity For Population Health

$251,830.00
Summary
As the prevalence of obesity at younger ages increases, people are living longer with obesity. We have recently shown that this has an increased risk of mortality and diabetes. In this project we will look at the extent to which an increasing length of time lived with obesity is also associated with increased risks of hypertension, heart disease, cancer, arthritis and disability. We will also look at the effect of this increasing duration on the overall health of Australian adults.
Preventing Mortality In Adults After Release From Prison: Advancing Global Knowledge Through An International, Individual Participant Data Meta-analysis

Summary
Ex-prisoners are at increased risk of death, but not enough is known about the incidence, timing, causes, context or risk factors for preventable death in this population. In this project we have compiled 18 cohorts of ex-prisoners (total number=1,159,290) and will analyse the data to determine exactly which ex-prisoners are at the greatest risk from what, and when. This new knowledge will inform policy changes to reduce the unnecessary loss of life in this vulnerable population.

Summary
The hepatitis C virus (HCV) is a major public health problem affecting over 170 million people worldwide. In Australia an estimated 157,000 people have HCV and are at risk of serious disease, and 16,000 new infections occur each year. Treating HCV-related disease is expensive, and this healthcare burden is projected to grow significantly in coming years.

In Australia an estimated 157,000 people have HCV and are at risk of serious disease, and 16,000 new infections occur each year. Treating HCV-related disease is expensive, and this healthcare burden is projected to grow significantly in coming years. Almost all new HCV infections in Australia occur among injecting drug users (IDUs), and despite our world-leading prevention programs, the virus is spreading. Consensus is emerging that the best hope for control of HCV and related disease lies in a vaccine; our research will lay much of the groundwork for its development. The applicants' research to date shows that IDUs are being infected with HCV more frequently than previously assumed, that many carry multiple strains, and that dominant strains vary rapidly in individuals over time. These results reinforce the view that our prevention methods will not reduce infection rates and that current anti-viral treatments are not the solution. Nevertheless, we also found that some IDUs remain free of HCV infection despite risky behaviour with infected associates; intensive study of the immune functioning of these persistently non-infected individuals holds promise for vaccine development. In our proposed research, a collaboration of leading Australian epidemiologists, virologists and immunologists, we will recruit 210 young IDUs and follow them regularly for two years. Recruits will describe their social networks and nominate IDUs with whom they inject, provide blood samples and be interviewed about their behaviour at 3-month intervals. Individuals with recent and resolved HCV infection, change of dominant strain and lack of infection despite risky behaviour will be identified and their blood analysed for genetic factors that may be linked to immune protection. The outcomes will be crucial to the development and trialling of a vaccine against HCV.Read moreRead less
‘The Hearts And Minds Study’: A Population Study Of Mental Health Trajectories, Cardiovascular Outcomes And Shared Biological Markers In Childhood And Mid-adulthood

Summary
Cardiovascular disease and mental illness are leading causes of mortality and morbidity. They frequently co-occur in adulthood, but it is poorly understand how and when this relationship develops. The Hearts and Minds Study will examine how mental health (positive and negative) over a 10-year period impacts cardiovascular health at two important life course stages: early childhood and mid-adulthood. Findings will enhance understanding of cardiovascular and mental health in our community.
I am an epidemiologist, primarily interested in environment and health (including the risk factors for autoimmune diseases, and the strongly-emerging issue of climate change and health). My other two continuing research interests are in diet, nutrition an
