  1. Integrating the Healthcare Enterprise Cross-enterprise Document Sharing for Imaging (XDS-I) Rita Noumeir Ph.D. University of Quebec IHE Technical and Planning Committees IHE Interoperability Workshop

  2. Abstract / Scope • Sharing of Imaging Information across health enterprises • Imaging Information includes • extensive sets of DICOM instances including images, evidence documents and presentation states • diagnostic reports provided in a "for display" form • selection of diagnostically significant images associated with the report content IHE Interoperability Workshop

  3. Sharing Radiology Reports and Imagesin a Regional Health Information Network Regional Health Information Network Radiology Enterprise B PACS B Radiology-to-radiology Radiology-to-Physicians PACS A Physician Office Radiology Enterprise A IHE Interoperability Workshop

  4. Sharing Radiology Reports and Imagesin a Regional Health Information Network Regional Health Information Network Radiology Enterprise B PACS B • Patient Id= 3547F45 • Report 5/21/1998 : CT Head B • Study 5/21/1998 : CT Head B • Report 2/18/2005 : Chest Xray A • Study 2/18/2005 : Chest Xray A Cross-Enterprise Registry PACS A Physician Office Radiology Enterprise A IHE Interoperability Workshop

  5. Physicians and Systems within a Regional Health Network - Routine Imaging Referral Register Imaging Information for sharing Priorimaging Reports & Studies Register Imaging Information for sharing Query for Documents Regional Health Information Network Radiology Enterprise B Cross-Enterprise Registry • Patient Id= 3547F45 • Report 5/21/1998 : CT Head B • Study 5/21/1998 : CT Head B Physician Office Radiology Enterprise A IHE Interoperability Workshop

  7. Physicians and Systems within a Regional Health Network for a Routine Imaging Referral Prior Imaging Report & Study Query for documents Notification of Doc Availability Imaging Report & Study Regional Health Information Network Radiology Enterprise B • Patient Id= 3547F45 • Report 5/21/1998 : CT Head B • Study 5/21/1998 : CT Head B • Report 2/18/2005 : Chest Xray A • Study 2/18/2005 : Chest Xray A Cross-Enterprise Registry Physician Office Radiology Enterprise A IHE Interoperability Workshop

  8. Value Proposition • Imaging component of the Electronic Health Record: Shared imaging Record, in a community, region, etc. • Effective means to contribute and access imaging documents across health enterprises. • Scalable sharing of imaging documents between radiology departments, private physicians, clinics, long term care, acute care with different clinical IT systems. • Easy access: Care providers are offered means to query and retrieve imaging documents (images and reports) of interest. IHE Interoperability Workshop

  9. Value Proposition • Distributed: Each Care delivery organization “publishes” imaging information for others. Actual images remain in the source/Image Manager. • Cross-Enterprise: A Registry provides an index for published information to authorized care delivery organizations belonging to the same clinical affinity domain. • Document Centric: Published clinical data is organized into “clinical documents”. using agreed standard document types (DICOM KOS, PDF and/or text report) • Document Content Neutral: Document content is processed only by source and consumer IT systems. • Standardized Registry Attributes: Queries based on meaningful attributes ensure deterministic document searches. IHE Interoperability Workshop

  10. XDS-I Dependencies • XDS-I depends on IT Infrastructure Cross-Enterprise Document Sharing (XDS) • Same Actors as in XDS • Document Source • Document Consumer • Document Registry • Document Repository • Documents, and metadata are specialized IHE Interoperability Workshop

  11. XDS-I Actors / Grouping • Sharing of an Extensive DICOM set • Document Source shall be grouped with an Image Manager/Image Archive • Sharing of a report that references selected images • Document Source shall be grouped with an Image Manager/Image Archive • Sharing of a report that references selected images from previously published extensive DICOM set • Document Source can be grouped with a Document Consumer IHE Interoperability Workshop

  12. XDS-I Actors and Transactions Patient Identity Source Patient Identity Feed Query Document Documents Document Consumer Registry Register Document Set Retrieve Provide & Register Document Document Set Document Document Repository Source Retrieve Images Image Manager Image Archive Retrieve Presentation States Retrieve Key Image Note Retrieve Evidence Documents IHE Interoperability Workshop

  13. XDS-I New Transaction requirements • XDS Actors: • Document Consumer • at least one Retrieve (DICOM C-Move) • Document Source • RAD-Y1 Provide and Register Document Set • Radiology Actors • Image Manager / Image Archive • RAD-Y6 WADO Retrieve IHE Interoperability Workshop

  14. XDS-IOptions • Document Source must support one of the following options: • Extensive Set of DICOM Instances • PDF Report • Text Report • Multipart Text/PDF Report IHE Interoperability Workshop

  15. Sharing of Extensive DICOM Instance Set IHE Interoperability Workshop

  16. Register Manifest Query Registry DICOM Manifest DICOM Manifest Retrieve Manifest Reference to image 1 Reference to image 1 Reference to image 2 Reference to image 2 Reference to image 3 Reference to image 3 Retrieve Images Manifest Manifest Manifest Manifest Manifest Clinical IT System Clinical Encounter Document Registry Document Repository IHE Interoperability Workshop

  17. Sharing of Extensive DICOM Instance Set • The shared Document is a manifest • a Key Object Selection DICOM Instance • Image Manager/Image Archive is required • to ensure that the referenced images from within a published manifest are available to be retrieved • Document Source is responsible • for replacing a previously submitted manifest Document when a change occurs to the manifest content (eg. Change of the DICOM SOP instances referenced within the manifest) IHE Interoperability Workshop

  18. Sharing of Imaging Report IHE Interoperability Workshop

  19. Radiology Report Header: Report Type: OB / Gyn BPD ….. ... Findings: ….. Gestational Impressions: Age ... Text Report PDF Report Text +PDF Report Radiology system Report Source IHE Interoperability Workshop

  20. Register Report Query Registry Radiology Report Header: Report Type: OB / Gyn BPD Retrieve Report ….. ... Findings: ….. Gestational Impressions: Age Report Report Report ... Clinical IT System Clinical Encounter Document Registry Document Repository Radiology system Report Source IHE Interoperability Workshop

  21. Sharing of Report • The shared Report Document format is • PDF, Text, or multipart PDF + Text • A report can • embed selected images in its PDF format • include fully resolved hyperlinks (interactively clickable) that point to the selected images • Document Source is responsible • for formatting the hyperlink to reference relevant images as a DICOM WADO URI or as IHE RID Request for Document • Document Source is required • to ensure that image references are valid links IHE Interoperability Workshop
