3.2.4 ADT/ACK - register a patient (event A04)

An A04 event signals that the patient has arrived or checked in as a one-time, or recurring outpatient, and is not assigned to a bed. One example might be its use to signal the beginning of a visit to the Emergency Room. Note that some systems refer to these events as outpatient registrations or emergency admissions. PV1-44-admit date time is used for the visit start date/time.
