Guide for use:

An emergency department stay episode ends when either the patient is admitted, died or, if the patient is not to be admitted, when the patient is recorded as ready to leave the emergency department or when they are recorded as having left at their own risk.

The phrase 'at the conclusion' in the definition refers to evaluation of findings interpreted by the clinician available at the end of the emergency department episode. This may include information gained from the history of illness, any mental status evaluation, specialist consultations, physical examination, diagnostic tests or procedures, surgical procedures and pathological or radiological examination.
