ABSTRACT
In Australia, heatwaves result in more fatalities than any other natural disaster, underscoring their significant public health impact. Heatwaves have been associated with heightened ambulance demand, and this study examines their relationship with emergency department (ED) presentations for circulatory and respiratory diseases. The analysis, focusing on the peak heatwave months of December and January over five years, revealed a positive correlation between maximum temperatures and ED presentations. Specifically, ED presentations increased by approximately 4.2% during heatwave periods and 3.9% during non-heatwave periods for every one-degree Celsius rise in maximum temperature. These findings suggest that, alongside well-recognised factors such as population growth and an ageing population, climate change poses an additional and significant challenge to the healthcare system. As maximum temperatures rise, the increased demand for emergency healthcare services could hinder the timely delivery of critical care, necessitating proactive planning and adaptation to ensure resilience in the face of a warming climate.
