Medical Document Management (MDM)

The management of medical records by transmitting new or updated documents or by transmitting important status information and updating records can be easily done using HL7 MDM. Trigger events and messages can be one of the two categories: either they convey the status of the document, or they produce the status of the document and contain the document contents. MDM messages are generated in relation to an order or independently of them.

The HL7 MDM has 11 different trigger events for the MDM message type as a standard. The commonly used MDM message is MDM T02 because it acts like an ORU or Result message. The MDM T-02 message notifies a system of creation of a document and includes the document contents.

An important part of the MDM message is the OBX segment. It contains document contents, because it is used to separate the body contents where headings or other separations may occur. Allthe MDM message will have the same structure except the OBX segment. When the message type contains document content then it is quite longer, many may also have repeating OBX segments based on how much of data has to be transmitted.

The HL7 MDM message helps manage medical records by transmitting new or updated documents, or by transmitting important status information and/or updates for the record. Trigger events and messages can be one of two categories: they can either describe the status of the document, or they can describe the status of the document AND contain the document contents. MDM messages can be created in relation to an order or independently of them.

There are 11 different trigger events for the MDM message type provided in the HL7 standard. The most commonly used MDM message is the MDM-T02 (Original document notification and content) because it acts like an ORU (Result) message. By definition, the MDM-T02 message notifies a system of creation of a document and includes the document contents.

The OBX segment is an important part of MDM messages that contain document contents, because it is used to separate the body contents along places where headings or other separations might occur. All MDM messages have the same message structure with the exception of the OBX segment. Message types that contain document contents are significantly longer, and may have repeating OBX segments depending on how much data needs to be conveyed.

The segments in the MDM-T02, T04, T06, T08 and T10 (which all contain document contents) are as follows:

The segments in the MDM-T01, T03, T05, T07, T9 and T11 (which do not contain document contents) are as follows:
