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.

Development Of A Sensitive Point Of Care Diagnostic Assay For Troponin I
Funder
National Health and Medical Research Council
Funding Amount
$137,650.00
Summary
This research aims to develop a diagnostic for immediate monitoring of patients presenting with chest pain, with the presumption of heart attack. The novel diagnostic platform will enable the estimation of a key indicator of heart muscle damage to be performed within a ten to fifteen minute window. This will aid speedier diagnosis and propoer triage of patients presenting with chest pain.
Feasibility Of Using Pre-hospital Point-of-care Troponin And Paramedic Risk Assessment In Patients With Chest Pain Without ST-elevation
Funder
National Health and Medical Research Council
Funding Amount
$132,743.00
Summary
Non-traumatic chest pain is the leading cause of ambulance services use in Victoria. Currently, there is no protocol for paramedics to determine which patients are high risk and suffering a minor heart attack, which results in delays in treatment. The aim of this project is to assess the feasibility of a risk assessment tool, including the use of point-of-care blood testing to detect heart attacks, to accurately risk stratify chest pain patients in the pre-hospital setting.
Improving Rapid Decision-Making In The Face Of Uncertainty: A Randomised Trial Of A 1-hour Troponin Protocol In Suspected Acute Coronary Syndromes
Funder

Funding Amount
$1,095,320.00
Summary
Chest pain patients are a large burden of emergency department demand. Their effective care requires timely risk assessment. High-sensitivity assays for heart muscle damage (troponin) increases the ability to detect patients at low risk for heart attack but treatment rules based on these tests have not been fully validated. This randomised trial of clinical decision making based on new troponin tests will provide a guidelines for their efficient and effective use in emergency department care.
The Limit Of Detection In The Emergency Department Trial: A Stepped-wedge Cluster Randomised Trial For Rapid Assessment Of Patients With Suspected Acute Coronary Syndrome In The Emergency Department
Funder
National Health and Medical Research Council
Funding Amount
$532,120.00
Summary
Over 450,000 patients present to Australian emergency departments with chest pain every year. The current approach to rule out heart attack for these patients is lengthy, costly and creates overcrowding in the emergency department. This is not sustainable in a system with growing demand and finite resources. This study will evaluate a rapid assessment pathway for investigating chest pain in the emergency department. The pathway will reduce healthcare utilisation while retaining patient safety.
Culture-independent Microbiology: Reducing Delays In The Diagnosis Of Severe Infections And Detection Of Antimicrobial Resistance From Days To Hours.
Funder
National Health and Medical Research Council
Funding Amount
$949,589.00
Summary
Serious infections require early effective antibiotic treatment. To provide evidence that an antibiotic will be effective, current tests take 2-5 days and this leads to a reliance on broad spectrum antibiotics, which can cause harm. Our new diagnostic methods, can produce results in 4-6 hours. We will demonstrate the real-world benefit of these methods by assessing samples taken from patients with three high risk infections and compare our test to currently available results.
Tapasin And Major Histocompatibility Complex Class I Antigen Presentation
Funder

Funding Amount
$226,650.00
Summary
An effective T cell response (cellular immune response) to infections is vital to a functional immune system. Normally, proteins are cleaved into small molecules called peptides and these peptides are in turn presented by Major Histocompatibility Complex molecules to T cells. However, we have only partial understanding of what determines the choice of peptides that are finally presented to T cells. Recent research suggests that a molecule called tapasin may also influence the choice of peptides. ....An effective T cell response (cellular immune response) to infections is vital to a functional immune system.

Recent research suggests that a molecule called tapasin may also influence the choice of peptides. This research proposal aims to examine the role of tapasin in this regard. A thorough understanding of the basic principles of peptide presentation to T cells is crucial to the design of effective vaccines. Furthermore it will also broaden our understanding of immunological responses to cancer, autoimmune diseases and infections.Read moreRead less
