Description
This indicator measures the time interval between the earlier of triage date/time or registration date/time and the date/time when a patient is admitted and leaves the emergency department (ED).
Interpretation

The 90th or 50th percentile of this indicator represents the maximum length of time that 90% or 50% of patients admitted from the ED spend in the ED.

A small number is desirable.

<div role="button" class="expandableTitle" aria-controls="backgroundRegion">Background, Interpretation and Benchmarks</div>
Rationale

Time is crucial to the effectiveness and outcome of patient care, especially for emergency patients. In conjunction with other indicators, this can be used to monitor the total length of time admitted patients spend in the ED in an effort to improve the efficiency and, ultimately, the outcome of patient care.

Multiple factors can influence the indicator results, including availability of inpatient beds, triage level, patient population and hospital resources.

Interpretation

The 90th or 50th percentile of this indicator represents the maximum length of time that 90% or 50% of patients admitted from the ED spend in the ED.

A small number is desirable.
