Guide for use:
For community health care, outreach services and services provided via telephone or telehealth, this may be the time at which the service provider presents to the patient or the telephone/telehealth session commences.
The time of patient presentation at the emergency department is the earliest occasion of being registered clerically or triaged.
The time that the patient presents is not necessarily:
the listing time for care (see listing date for care for an analogous concept), nor
the time at which care is scheduled to be provided, nor
the time at which commencement of care actually occurs (for admitted patients see admission time, for hospital non-admitted patient care and community health care see service commencement time).
