  1. Emmanuel Cordonnier, John Donnelly Point-to-Point and MediaDocument Interchange(PMI) orCross-Enterprise Document Interchange (XDI)

  2. Overview • generic mechanism for conveying a set of medical documents between parties • "neutral" vis-à-vis the document content • as much as possible compatible with XDS • as much as possible compatible with PDI • using two transport mechanisms: • (secure) mail • portable media (CD / USB key) IHE ITI Point-to-Point & Media Document Interchange

  3. Use cases • consulting to referring physicians communication • specialized healthcare networks • hospital-doctor communication • remote advice and patient transfer • personal health record (PHR) to ED/primary care EMR • acute care discharge to extended care facility (ECF) IHE ITI Point-to-Point & Media Document Interchange

  4. Japanese Merit-9 specs CD CD Clinic Hospital DICOM Images IHE-PDI Patient’s home Referral Lab Px MERIT-9 IHE ITI Point-to-Point & Media Document Interchange

  5. French EDISanté GT11 specs Text note, or message encoded in ASCII (HL7…) .txt Report or letter, including presentation features .rtf Structured document referencing files (CDA…) .xml Hidden files, used by other documents (XSLT…) Tile of DICOM images Vocal comment, dictation or signal Envelope header: patient demographics, Patient ID(s), author, recipient… John Smith12/30/1957 IHE ITI Point-to-Point & Media Document Interchange

  6. German DICOM E-mail IHE ITI Point-to-Point & Media Document Interchange

  7. HL7 Attachments IHE ITI Point-to-Point & Media Document Interchange

  8. Open Issues • ebMS vs. MTOM over SMTP ? => re-use ebMS (for the moment) with the MTOM multipart/related « flavors » • Meta-data to be added (sender, recipients…) • One vs. Set of submissionSets on a media => set of, without « metadata manifest », only index.html • Links from documents to images « conveyed » together => use the XDS-I manifest IHE ITI Point-to-Point & Media Document Interchange

  9. Effort Estimates • « middle » (would be large w/o XDS) • => re-use the XDS approach, explanations (« document neutrality… ») and meta-data • Create 1, 2 3 or 4 new actors • Document [Sender /][Exporter /] [Source] • Document Receiver [/ Importer] • Create 3 new transactions • Send document set • Export document set(s) / Import document set(s) IHE ITI Point-to-Point & Media Document Interchange
