Significant and sustained increases in acute demand put pressure on Australian hospitals to treat patients effectively and efficiently, so this project is exploring how predictive modelling can improve patient flow, satisfaction, and outcomes in Queensland Emergency Departments (EDs).

Queensland is currently the only state that does not provide ED waiting time information in real-time, and existing technologies interstate do not harness the potential of AI-algorithms. Dr Anton Pak has previously demonstrated that machine learning algorithms significantly outperform commonly used predictors of ED waiting times, such as rolling averages (see research article below). In collaboration with the Princess Alexandra Hospital in South Brisbane, this project extends this research into developing and testing a prototype model that can predict waiting times with a high degree of accuracy. The Princess Alexandra Hospital has described his work as having “great potential for improving patient experience and delivering significant cost savings to the hospital” (Dr James Collier, 2022).
