Answer 1

Patient Administration (ADT) messages are used to exchange the patient state within a healthcare facility. HL7 ADT messages keep patient demographic and visit information synchronized across healthcare systems.

ADT is the most commonly used HL7 messaging type, with most clinical applications, enabled to receive key ADT messages.

ADT messages are used to communicate events about a patient (Admitted, Discharged, Transferred) to different clinical systems within a hospital. This way all systems in the hospital know the patient's location and status. This allows the clinical applications to do things such as schedule procedures, or prescribe medications. ADT messages (HL7 messages in general) allow the applications to exchange data about patients.
