What Is an ADT Message?

October 5th, 2006 by HL7 Standards Print Friendly

HL7 terms to better understand what is HL7. Patient Administration (ADT) messages are used to exchange the patient state within a healthcare facility. 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 within the HL7 standard are typically initiated by the Hospital Information Systems (HIS), or a registration application, to inform ancillary systems that a patient has been admitted, discharged, transferred, merged, that other demographic data about the patient has changed (name, insurance, next of kin, etc.) or that some visit information has changed (patient location, attending doctor, etc.).

    What is the relation between ADT message and eMAR ( electronic Medication Administration Record)

  • Mike

    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 patients 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.

    eMar systems keep records of medications administered to patients. That is an over simplified summary, but that is their main purpose.

    In a hospital setting you would probably find that the eMar system is receiving ADT messages from the HIS system in order to populate the list of available patients and track their locations.
