Computation description:Help on this term

The definitions applied are consistent with the national definitions used for reporting against the National Partnership Agreement on Hospital and Health Workforce Reform. The definitions include presentations that have been assigned a triage category between 1 and 5.  Presentations that are ‘did not wait’, ‘dead on arrival’ or the waiting time to service delivery is invalid are excluded for the purpose of calculating this indicator. See Australasian Triage Scale from the Australasian College for Emergency Medicine for a description of each triage category, including indicative clinical descriptors.

Time to treatment is calculated by subtracting the date and time the patient presented to the emergency department from the date and time treatment commenced. The time to treatment is then compared to the recommended treatment time for the allocated initial triage category. 

The indicator is calculated for triage category 2 and presented as a percentage.
