Collection and Usage Attributes
The number of days is calculated by subtracting the Outpatient clinic service request-receipt date from the patient's initial attendance date for an appointment. The waiting time calculation includes weekends and public holidays.

The calculation excludes any days the patient was waiting with a less urgent clinical urgency category (excluding supplementary codes), any days the outpatient clinic service was awaiting further information from the requesting service, as well as any days the patient was not ready for care.

In cases where the clinical urgency category is upgraded the waiting time count is restarted from the recategorised date. For example, when a clinical urgency category is upgraded from a category 3 to category 1, the waiting time count starts from the date the category code was changed to a category 1.
