  4. Why do we need need Integrating the Healthcare Enterprise (IHE) ? • Healthcare data communication standards are written to support a wide range of healthcare situations and include many optional features. • Different suppliers implement different features – hence interoperability problems • IHE is a not-for-profit organisation that enables healthcare IT system users and IT suppliers to work together to obtain clinical interoperability by selecting existing standard features to fit the IT requirements for specific clinical tasks • The home of IHE-UK is the British Computer Society)

  5. Who is IHE? IHE (International) Strategic Development Committee SponsorsCo-Chairs Global reports supervises Interoperability IHE North America IHE Europe IHE Domain-related Planning and Technical Committees IHE Asia/Oceania Global Development:IT Infrastructure,Radiology,Cardiology,Lab, etc. Regional &NationalDeployment Delegates contribute Participants

  6. Standards Adoption Process Testing at Connectathons IHE Demonstrations Develop technical specifications Products with IHE Identify available standards (e.g. HL7, DICOM, IETF, OASIS) Timely access to information Document Use Case Requirements Easy to integrate products

  7. Connectathon Barcelona 2006 • 300+ participants, 120+ systems • 60+ systems developers • 2800+ monitored test cases

  8. IHE integration profiles • An IHE integration profile includes definitions of • A specific clinical task (use case) • Which data items in existing standards are to be used to exchange essential task information - overriding optionality • Essential application entity task processes • Supplier web sites show products that support IHE profiles • Purchasers can buy products from different suppliers that will work properly as specified by IHE profiles

  9. Evolution of IHE Domains • IHE Global Developments • Integration Profiles – Solutions to Real-World Interoperability Needs & Problems: • Within Clinical Departments e.g.: • Radiology • Cardiology • Lab • ... • Across Departmental &Institutional Boundaries – XDS • Regional/national Healthcare Information Exchange • HIT Enablers Veterinarian Endoscopy (1) Eye Care / (3) Ophthalmology Year 7 (2005) Year 1 (1999) Year 2 (2000) Year 3 (2001) Year 4 (2002) Year 5 (2003) Year 6 (2004) Year 8 (2006) Pharmacy Pathology (1) Patient Care Devices (1) Patient Care Coordination (5) Radiation Oncology (1) Laboratory (6) Cardiology (7) IT Infrastructure for Healthcare (17) Radiology (18)

  10. IHE-EUR countries and participants • Denmark • France • Germany • Israel • Italy • Netherlands • Norway • Spain • Sweden • United Kingdom Users, HC Authorities, Vendors: 40% single country vendors60% multi-countries vendors Example: IHE-Netherlands

Hospital Record pointers to documents Clinic Record Specialist Record 3-Documents returned 4-Patient data presented to clinician Aggregate Patient Info ebXML Document registry/ Patients IDs Manager Clinical IT System 2-pointers to documents found 1-Search for certain documents Clinical Encounter IHE-XDS components Community or sub-network (Affinity domain) Local documentrepository Centralizeddocument repository

  13. IHE Document sharing IHE Clinical document sharing • Any format PDF, JPEG (Images), DICOM Images, CDA, etc • Proven specifications • Multiple suppliers • Support for multiple patient identifiers • Email notification of availability of documents • Security metadata item • Registry can point to hardcopy and/or electronic documents REPOSITORY

  14. IHE-UK Current Key Projects • Support for Humber XDS project Multi Disciplinary Team support in planning stage • XDS UK search data spec for Doc Class and Sub-class • XDS UK user guides • Support for image sharing between institutions:IHE XDS-I, ISO WADO-WS, ISO WARM • Work with ProRec UK on step by step implementation of improved EHRs

  15. IHE Benefits to users • Users benefit because they can know exactly what functionality will be implemented in purchased products for which conformance to IHE specifications is stated • Easy resolution of any interoperability problems that do arise at commissioning • Easy replacement of systems • Easy extension of networked systems • Future proofing of investment

  16. IHE Benefits to suppliers 1 • Clear requirement specifications from users • Easy implementation of systems that interoperate • Connectathon: testing their software with a number of different suppliers. They can learn more in one week at the connectathon than several months at base • Reduced costs of commissioning on site • If IHE is specified then you know what to do to get paid • IHE specifications can shorten product development time

  17. IHE Benefits to suppliers 2 • Work with users and other suppliers to create applications that work well in the real world • Support development • IHE-UK Specific extensions to the core IHE Integration Profiles • IHE-UK Guidance notes regarding use of IHER specs in the UK • Collaborate with other suppliers in creating solutions for large multi enterprise (or multi-department) facilities • Obtain a deep understanding of the benefits of the IHE methodology
