Heat related Vulnerability Index

The spatial distribution of heat related vulnerability in the greater Adelaide metropolitan region suggests that areas of higher risk are concentrated in the suburbs north and south of the city. This corresponds to areas with a high number of people who need assistance with daily activities and the time needed to travel to a hospital emergency department. The time needed to travel to hospital is negatively correlated with emergency department (ED) presentations meaning more of the patients came from areas closer to the hospital than further away.

ED presentations on extreme heat days

Emergency department (ED) presentations for all persons triaged as category 1, 2 and 3 (requiring immediate attention) between 1/1/2004 and 31/12/2010 were used to measure emergency health outcomes in all Adelaide metropolitan hospitals. Extreme heat days were defined using a daily minimum temperature threshold of 31°C. The highest incidence rate for emergency department presentations (marked as red on the map) was in the suburbs north and south of the city.
