Cross-enterprise Document Media Interchange
Cross-Enterprise Document Media Interchange (XDM) - provides document interchange using a common file and directory structure over several standard media. This permits the patient to use physical media to carry medical documents. This also permits the use of person-to-person email to convey medical documents.
Facilitates person-to-person exchange of the healthcare information
- supports transport via physical media - USB and CD-R
- supports transport as an attachment to an email
The XDM solution is intended to be easy to implement with pre-existing email clients, CD burners and USB ports. XDM does not include any additional reliability enhancements. XDM requires that the recipient be able to support human intervention in order to manually control the importing of the data (patient ID reconciliation, selection of patient of interest from possibly multiple patients’ documents on the media).
XDM is document format agnostic, supporting the same document content as XDS and XDR. Document content is described in XDS Document Content Profiles. Examples are XDS-MS, XPHR, XDS-SD, and XD*-LAB.
XDM defines no new metadata. It leverages XDS metadata with emphasis on patient identification, document identification, description, and relationships. A directory and file structure is documented for populating the media. This structure maintains separate areas for each patient listed and is supported on all referenced media types. Media and the structure were selected based on experience with media interoperability in Radiology, i.e. PDI profile. The media selected are the widespread CD-R, USB removable media, and email with ZIP attachment.
