QUT Professor Anne Chang has been awarded a $2,588,607 Medical Research Future Fund grant to lead a multidisciplinary, multi-institution project.
The project is titled “Improving outcomes of recurrent preschool wheeze: a multicentre randomised controlled trial with biomarker discovery”.
Professor Chang, from QUT School of Public Health & Social Work said that although wheezing in preschool children was common with a higher morbidity than other asthma groups, doctors and parents disagreed more than 50 per cent of the time on whether wheezing is present in a child.
“This may cause under– or over-diagnosis of asthma and lead to over or under-use of medications, children having to undergo unnecessary procedures and high parental anxiety,” Professor Chang said.
“However, it would be poor practice to give all children asthma medication which can have adverse effects.
“Our multicentre study will address the need to manage recurrent preschool wheezing (PSW) by objectively identifying it with an AI-developed tool (WheezeScan), and an appropriate management plan.
“In addition, our planned discovery arm based on pilot data, using blood gene expression markers and saliva extracellular vesicles, will address the need for a reliable biomarker.”
The project will recruit 206 children with recurrent PSW from hospitals and community clinics, including from remote Indigenous clinics, to test the intervention of definitive wheeze identification followed by appropriate management.
“The primary aim is to reduce unscheduled doctor visits and other clinically important outcomes: hospitalisation, time to next unscheduled doctor visit, improved quality of life,” Professor Chang said.
“We will also evaluate its cost-effectiveness.”
The study will be conducted in Brisbane, Indigenous Outreach clinics, Sydney, Melbourne, Perth and Darwin.
