Townsville University Hospital (TUH) evolved the first Quantitative fit testing (QnFIT) for N95 masks in Queensland and working with the University of Queensland (UQ) and COVID-19 analytics division have created a novel eHealth Maskhelper tool. This has now been endorsed by Queensland Health's COVID-19 Response Group to allow for operational standardisation, minimise wastage, inform manufacturers of mask requirements and potentially create a mathematical model that uses facial recognition software to obviate the need for the estimated 100,000 annual fit testing requirements throughout Queensland as part of employment safety law.
The program will also provide data capture for Queensland Health and Queensland Ambulance Service supporting a universally acceptable Fit Test Passport.
Ehealth MaskHelper Tool - a novel strategy using QnFIT testing to inform AI based facial recognition
Summary
Aim
To leverage facial recognition analysis gained during employer mandated Quantitative Fit Testing to achieve operational standardisation and cost efficiency by reducing wastage and enabling smarter central procurement.
Benefits
• achieve uniformity, standardisation and ensuring repeatability across Queensland Health through a comprehensive package
• cost saving via central procurement and has further ability to inform mask design through innovation
• preparedness for future airborne pandemics
• minimising annual fit-testing requirement using AI based evaluation
• ability to create a Fit Test Passport between HHSs.
Background
Maintaining safe and high-quality care systems and services during COVID-19 has been a major challenge for health providers. The use of technology has been a driving force in improving health outcomes, for Queensland’s First Nations people in particular.
Solutions Implemented
- More than 1,200 participants were fit tested via a research methodology capturing facial characteristics (September 2020 to March 2021)
- Tripartite collaboration with COVID-19 analytics team and University of Queensland to develop an AI based tool to reduce mask wastage and improve efficiency
- First HHS in the state to take a scientific research based approach
- AS1715:2009 standards were applied, using a four-test protocol to remove individual bias
- Creation of a ehealth MaskHelper tool, hosted on the Queensland Health intranet with current expressions of interest from 10 HHSs, the Queensland Ambulance Service and Mater Hospital, Brisbane with the ability to deliver real time solutions and feedback statewide.
Evaluation and Results
Phase 1 proof of concept study has been completed across 1,200 participants at the Townsville Hospital and Health Service (THHS) site.
The results have been presented as part of the Statewide PPE working group, endorsed by the Deputy Director-General, Clinical Excellence Queensland and also as of 8 June; the COVID-19 Response Group.
