Time spent in emergency department from arrival to departure
Median time spent in the emergency department
Data source
National Non-Admitted Patient Emergency Department Care Database (NNAPEDCD).
Before 2015–16, data were provided according to the Non-admitted patient emergency department care national minimum data set specification (NAPEDC NMDS).
In 2015–16, Queensland provided data according to the Non-admitted patient emergency department care data set specification (NAPEDC DSS), while other states/territories provided data according to the NAPEDC NMDS.
In 2016–17 and 2017–18, Victoria (excluding Albury hospital), Queensland and Western Australia provided data to the NNAPEDCD using the national best endeavours data set (NBEDS) specification, while all other states and territories provided data to the NNAPEDCD using the NMDS specification.
About the measure
Time spent in the emergency department is the time between the patient’s arrival (presentation) at the emergency department and their physical departure.
The cohort includes patients presenting to the emergency department with any type of visit code.
The median is the time until half of the patients (50%) had departed the emergency department.
Results are presented for all patients, and by triage category; by patients admitted to the same hospital from emergency department and by patients discharged from emergency department.
The patients included in the ‘discharged from the emergency department’ measure are patients who: ‘departed without being admitted or referred’, were ‘referred to another hospital for admission’, ‘did not wait’ to be attended by a health care professional, ‘left at own risk’ before care was completed, ‘died in the emergency department’, were ‘dead on arrival’, or were ‘registered, advised of another health care service, and left the emergency department without being attended by a health care professional’.
Calculating the measure
‘Number of patients’ refers to all presentations for each category.
The median time spent in emergency departments is calculated as the time between patient presentation and physical departure for the patient at the 50th percentile, which means that half of patients’ waiting times are either the same or less than this waiting time. The median is the time until half of the patients (50%) had departed the emergency department. Only data which met certain criteria are included in the calculation. The criteria for calculating and presenting results are:
- Valid times for presentation and physical departure
- Valid departure status ( episode end status) for measures of time spent by patients admitted to the same hospital or patients discharged from emergency department
- 10 or more presentations in the category (in the denominator).
Time until most patients (90%) had departed the emergency department

Calculating the measure
‘Number of patients’ refers to all presentations for each category.
The time until most patients had departed the emergency department is calculated as the time between patient presentation and physical departure of the patient in the 90th percentile of times in that category.
Only data which met certain criteria are included in the calculation. The criteria for calculating and presenting results are:
- Valid times for presentation and physical departure
- Valid departure status ( episode end status) for measures of time spent by patients admitted to the same hospital or patients discharged from emergency department
- 10 or more presentations in the category (in the denominator).
