3.2.3 ADT/ACK - discharge/end visit (event A03)
3 segments
An A03 event signals the end of a patient's stay in a healthcare facility. It signals that the patient's status has changed to "discharged" and that a discharge date has been recorded. The patient is no longer in the facility. The patient's location prior to discharge should be entered in PV1-3-assigned patient location.
An A03 event can be sent to notify: the pharmacy that the patient's stay has ended and that entitlement to drugs has changed accordingly; the nursing system that the patient has been discharged and that the care plan can be completed; the finance system that the patient billing period has ended; and/or the clinical repository that discharge has taken place for the EMR.
