3.2.9 ADT/ACK - patient departing - tracking (event A09)
3 segments
The A09 and A10 (patient arriving-tracking) events are used when there is a change in a patient's physical location and when this is NOT a change in the official census bed location. There are three situations that qualify as non-census location changes: (a) patient tracking, (b) the patient is in transit between locations for some time, (c) a notification of temporary location change.
Patient tracking: This can be used when the nursing application sends a "transfer" before the Patient Administration (or official census) system issues an A02 (transfer a patient) event. If the patient has left for a non-temporary location and is not in transit, then the PV1-3-assigned patient location must contain the new patient location, while PV1-6-prior patient location must contain the old patient location.
