Presented by Eugene Igras UPDATE Adoption of standards to share diagnostic imaging information in the pan-Canadian EHR DICOM Standards Committee – December 4, 2008

2008 Canada Health Infoway Inc. 2 Agenda Sharing DI data in the pan-Canadian EHR context Adoption of standards in the DI Domain Issues to be addressed 2008 Events Conclusion

2008 Canada Health Infoway Inc. 3 Infoway Diagnostic Imaging Program Vision Foster and accelerate the development and adoption of DI solutions to assist healthcare providers in acquisition, collection, storage, management, distribution and viewing patient radiology reports and images (any study, any time, any where) regardless of where the DI tests were conducted and/or the reports transcribed. Strategy  Build on existing standard-based PACS / RIS capabilities  Use IHE XDS/XDS-I Integration Profiles to:  Implement Registry & Data Repository (or multiple Repositories)  Enable interoperability with the EHR components, including: Clinical Viewer Health Information Access Layer (privacy & security, consent management) Registries (Client, Provider, Site and Terminology)  Ensure privacy and security of DI information

2008 Canada Health Infoway Inc. 4 Improve Access to Services  Provide timely access to DI information irrespective of where the images were acquired and/or the report transcribed  Provide access to a longitudinal record of patient DI history  Improve timeliness and continuity of care  Enable real-time collaboration and clinical consultations  Improve training opportunities Improve Productivity & Contain Costs  Increase patient throughput, reduce patient transfers and wait times  Provide capabilities for Radiologists to share workload across the region  Reduce DI exams by reducing avoidable retakes Improve Quality of Care  Improve quality of DI information (accuracy, completeness, consistency)  Reduce radiation exposure  Reduce medical errors Value Proposition

2008 Canada Health Infoway Inc. 5 Common Approach Adherence to Infoway DI Program vision  Leverage existing RIS and PACS as operational film-less solutions  Consolidation of DI data into DI Repository (DI-r) or multiple Repositories  Seamless sharing of DI data among authorized users  Provide access to a longitudinal record of patient DI history Conformance & Compliance to Standards  Architecture: EHRS Blueprint v2  Privacy & Security:Jurisdictional privacy protection legislation Privacy & Security Requirements & Architecture ISO/IEC  Content & Messaging: HL7 v2.x and v3, CDA, DICOM  Terminology:SNOMED CT & other terminology standards  IHE Integration Profiles:XDS/XDS-I - to support DI data sharing PIX/PDQ – to support patient identity/CR with HL7 v3 ATNA – to support security Other IHE Radiology and IT Profiles  Electronic Business & Internet Standards

2008 Canada Health Infoway Inc. 14 How to ensure interoperability of XDS-based systems with other solutions that handle discrete data (e.g., Lab, Drug)?  How does an XDS Registry for DI evolve into and/or co-exist with other indexing scheme?  How to ensure other XDS/XDS-I consumers (e.g., EMR) adopt Document Consumer actor capabilities to access DI content? How to provide document sharing capabilities across multiple affinity domains? How to ensure data quality attributes (e.g., accuracy, completeness, integrity) are maintained/preserved in a data sharing environment? How to provide a uniform clinical terminology given a multitude of terminology schemes and vocabularies? How does a jurisdiction approach XDS Affinity Domain policies for consumers that are “associated “with the Affinity Domain (GP, Specialist) but not “in” the Affinity Domain? Issues To Be Addressed (1)

2008 Canada Health Infoway Inc. 15 Issues To Be Addressed (2) Synchronization of shared radiology studies  Radiology study split  Radiology study attribute changes  Deletion of a study component (e.g. radiology image) Standardized representation of DI study in the XDS Affinity Domain  A single manifest  Multiple manifests Standardized use of XDS Affinity Domain attributes and metadata Division of responsibilities between PACS and DI-r Data synchronization between local PACS systems and DI-r Linking of documents from multiple repositories and support for consultation workflows including creation of new objects
