The Australian Research Data Commons (ARDC) invites you to participate in a short survey about your
interaction with the ARDC and use of our national research infrastructure and services. The survey will take
approximately 5 minutes and is anonymous. It’s open to anyone who uses our digital research infrastructure
services including Reasearch Link Australia.
We will use the information you provide to improve the national research infrastructure and services we
deliver and to report on user satisfaction to the Australian Government’s National Collaborative Research
Infrastructure Strategy (NCRIS) program.
Please take a few minutes to provide your input. The survey closes COB Friday 29 May 2026.

This project will update the Wittenoom cohorts by tracing cancers and deaths in Australia and Italy. This will improve risk estimates of lung cancer and mesothelioma. In particular we will see if that risk declines with more than 40 years since exposure, in collaboration with Italian colleagues. We will continue developing an interactive community website to act as a support platform, a layman's bridge to medical research knowledge, public health information and an archive of personal stories.
Understanding Health Professionals' Infection Control Practices In The Acute Care Setting
Funder

Funding Amount
$151,196.00
Summary
Health-care acquired infections have a considerable personal, social and economic impact in Australia, and better understanding of the causes of these infections is necessary. Failure by health professionals to follow infection control recommendations has important consequences in terms of the personal risk of acquiring an infection as well as the risk of infection transmission to patients. In Australia surgical site infections alone are estimated to cost as much as 268 million dollars a year. H ....Health-care acquired infections have a considerable personal, social and economic impact in Australia, and better understanding of the causes of these infections is necessary. Failure by health professionals to follow infection control recommendations has important consequences in terms of the personal risk of acquiring an infection as well as the risk of infection transmission to patients. In Australia surgical site infections alone are estimated to cost as much as 268 million dollars a year. Health-care acquired infections are associated with poorer health outcomes, a greater probability of prolonged hospital stays, greater re-hospitalisation rates, and significant reductions in health related quality of life. In this qualitative study we will use grounded theory and a comparative analysis strategy. We will initially identify participants sampled from health professionals employed in the acute care setting at a major teaching hospital in Perth, Western Australia. We will seek representation of a range of health professionals recruited from multiple occupational groups, including doctors, nurses and paramedical staff who have direct patient contact in the study sample. Sampling will also aim to recruit participants from a number of different acute care areas within the hospital, and staff with a range of individual characteristics, experiences and beliefs. We will interview a range of health care workers in order to explore their experiences of engagement in infection control practices and the factors influencing these experiences. We aim to develop a substantive theory that explains health professionals' engagement in high-risk infection control practices in the acute care setting. This will have implications for current understandings of the factors influencing adherence to recommended infection control practices, current theoretical perspectives which guide infection control practice, and strategies used to promote compliance with recommended practices.Read moreRead less
Emerging Techniques For Earlier Diagnosis And Assessment Of Severity And Progression Of Artificial Stone Silicosis

National Health and Medical Research Council
Funding Amount
$994,642.00
Summary
Stonemasons who have worked with engineered stone have been shown to develop a rapidly progressive and potentially fatal form of silicosis. This research will use data from affected workers from Victoria, Western Australia and Queensland. The research will comprise a suite of projects to investigate many uncertainties related to radiological screening methods, as well as investigating new methods to assess disease severity and identify indicators of progression to inform future practice.
Immunological And Respiratory Effects Among Workers Exposed To Engineered Nanoparticles
Funder
National Health and Medical Research Council
Funding Amount
$513,507.00
Summary
Laboratory studies suggest that nanoparticles can easily enter the body and may cause more damage than similar, larger particles but human data are lacking. We propose to study the health of nanoparticle-exposed workers and unexposed workers, and compare biomarkers of inflammation in the blood and the respiratory system at the start and end of the shift, end of the working week and after 1 year’s further exposure to nanoparticles.
Asbestos And Related Diseases In Western Australia

National Health and Medical Research Council
Funding Amount
$404,727.00
Summary
This project will extend the follow-up of large, well established groups of people who have experienced significant exposure to blue asbestos, either through their jobs or environmentally. Mesothelioma, lung cancer and asbestosis are common among these groups. This study will provide information on the effects of different levels of exposure to blue asbestos. Ways in which these diseases may be prevented through the diet and other lifestyle habits will be closely examined. This project provides ....This project will extend the follow-up of large, well established groups of people who have experienced significant exposure to blue asbestos, either through their jobs or environmentally. Mesothelioma, lung cancer and asbestosis are common among these groups. This study will provide information on the effects of different levels of exposure to blue asbestos. Ways in which these diseases may be prevented through the diet and other lifestyle habits will be closely examined. This project provides important data on the dose-response effects of a known carcinogen. Due to the integrated nature of our already established follow up systems we are in a unique position worldwide to achieve these aims. The dose response relationships between exposure and disease identified by this study will contribute to occupational health and safety exposure standards and compensation policy in Australia. The information on lifestyle factors is appropriate for use in many different health promotion interventions. Ongoing contact with the cohorts is critical to our involvement in collaborative preventative and biological studies.Read moreRead less
Sex-related Changes In Asthma During The Transition Through Puberty In The CAPS Birth Cohort
Funder
National Health and Medical Research Council
Funding Amount
$831,581.00
Summary
Early adolescence is a critical period in the life of people with asthma. Some children grow out of their asthma and others acquire the disease for the first time. There are important sex differences in the pattern of change. We believe these changes are related to the passage through puberty. This study will examine changes in the features of asthma and allergy during this period and their relation to early life and current environmental exposures.
Mechanisms Of Epithelial Damage By The Noxious Smoke Constituent Acrolein
Funder
National Health and Medical Research Council
Funding Amount
$668,813.00
Summary
Due to increasing use of reactive chemicals by terrorists (e.g. chlorine gas), their effects on the lung are receiving increasing attention in the global toxicology community. This project focusses on acrolein, the major cytotoxic substance present in smoke produced on combustion of organic matter. We will explore the mechanisms whereby acrolein and high doses of smoke cause the lung to lose its watertight properties, and also test ways of preventing such damage with drugs.
