Length of stay
The progress of the patient through the ED is recorded using 5 different time points: presentation time, triage time, clinical care commencement, episode end time and physical departure time as depicted in Figure 1.
These can be used to calculate the length of stay for 50% and 90% of patients, as well as the proportion of patients whose ED stay was completed in 4 hours.
The length of stay is calculated as the time spent in the ED, from arrival to physical departure. Comparisons of length of stay statistics by state and territory are provided in the sub sections below.
