This paper explains how routinely collected data can be used to examine the emergency department attendances of Victorian Aboriginal and Torres Strait Islander people. The data reported in the Victorian Emergency Minimum Dataset (VEMD) for the 2006/2007 financial year were analysed. The presentations of Aboriginal and Torres Strait Islander and non-Aboriginal people were compared in terms of age, gender, hospital location (metropolitan and rural) and presenting condition. Aboriginal and Torres Strait Islander people were found to attend the emergency department 1.8 times more often than non-Aboriginal people. While the emergency department presentation rates of metropolitan Aboriginal and Torres Strait Islander and non-Aboriginal people were similar, rural Aboriginal and Torres Strait Islander people presented to the emergency department 2.3 times more often than non-Aboriginal people. The injuries or poisonings, respiratory conditions and mental disorders presentation rates of the Aboriginal and Torres Strait Islander and non-Aboriginal population were compared. No previous studies have assessed the accuracy of the Indigenous status and diagnosis fields in the VEMD; therefore the quality of this data is unknown.
