ADT A05: Pre-Admit a patient
Records an expected future admission of a patient. Additionally, an appointment will be created in the patient's calendar.
This is identical in format to the ADT A01, except that an [[Appointment]] entity will also be populated. In addition, since this message is typically used for future events, PV2-8 and EVN-3 will also be considered when determining both the event timestamp and the appointment start time. This is shown below.
