  1. Integrating the Healthcare Enterprise The IHE Process: Developing Standards-based Solutions Kevin O’Donnell Co-chair, IHE Radiology Planning Committee Manager, Systems Solutions, Toshiba Medical Systems

  2. Goals of IHE • Increase the rate and quality of integration in healthcare environments. • Foster communication among vendors. • Prove that integration is attainable through the use of standards. • Improve the efficiency and effectiveness of clinical practice. IHE Canada Videoconference

  3. “Improve the efficiency and effectiveness of clinical practice” • Improve Workflow • Improve Information Accuracy • Improve Information Availability • Enable Cross-System Functionality IHE Canada Videoconference

  4. How Does IHE Work? A joint initiative to improve systems integration: • Clinicians define system integration needs • Vendors use a well-defined process to develop standards-based solution profiles – the IHE Technical Framework. • Societies (HIMSS/RSNA/ACC) supervise documentation, testing, demonstration, and promotion of the profiles. IHE Canada Videoconference

  5. “IHE drives standards-based integration in healthcare” IHE Canada Videoconference

  6. Key IHE Concepts IHE Canada Videoconference

  7. Actor • A generalized system function: • Order Placer • Order Filler • Acquisition Modality • Image Manager • Report Creator • Implementers choose which Actors to include in a system • Systems may group several Actors IHE Canada Videoconference

  8. Transaction • An interaction or exchange of data between actors • Based on open standards • Strictly specified to avoid incompatible implementations (retire options, clarify data model, etc.) • Represents an actors interface with the rest of the world • System internal functions are out of scope, e.g. • single system functions • transactions between actors inside the same system IHE Canada Videoconference

  9. Integration Profile • A Problem/Solution Scenario • For each Integration Profile: • the context is described (what real-world problem is addressed) • the actors are defined (what systems are involved) • the transactions are defined (what do they have to do) IHE Canada Videoconference

  10. IHE Process • Identify a specific information flow between several systems • Define a coherent set of actors & transactions • For each transaction: • Select an existing standard (e.g. HL7, DICOM) • Detail how to use the standard to implement the transaction • Bundle it up as an “Integration Profile” • Do Cross-vendor testing at a “Connectathon” • Use Integration Profiles as a Common Language for: • Vendors to claim in Integration Statements • Users to request in RFPs IHE Canada Videoconference

  11. IHE Canada Videoconference

  12. IHE Technical Framework • Volume 1: The Profiles • Identifies the actors and transactions • Describes the integration scenario • Volume 2 (and 3): The Transactions • Provides implementation specification for each transaction • Volume 4: The National Appendices • Documents national clarifications and extensions IHE Canada Videoconference

  13. IHE Connectathon • Voluntary Participation • Project Management by Mallinckrodt • Pre-Validation Tools (MESA) • Defined Test Protocols with Verification • Engineering event • code changes are not a problem • Massive Cross-vendor Testing IHE Canada Videoconference

  14. RFPs & IHE Integration Statements • Be Brief? • “The system must support DICOM” • Be Effective? • “The system must support the following DICOM services according to the following 100 pages of specifications” • Be Both: • “The system must support IHE Scheduled Workflow as an Acquisition Modality” • IHE Integration Statements • Version 2.1 of the Jupiter 3 CT supports IHE Scheduled Workflow as an Acquisition Modality IHE Canada Videoconference

  19. IHE Advantages • The problems are identified by the users • The solutions are vendor/application neutral • The profiles package relevant chunks of standards into useful real-world bundles • Where HL7 & DICOM provide Dictionaries, IHE provides a Phrasebook • The connectathon enables broad cross-vendor testing of implementations • The profiles simplify effective communication between vendors and users IHE Canada Videoconference
