1. Integrating the Healthcare Enterprise Overview of IHE & the 7 Profiles Kevin O’Donnell - Toshiba Corp. IHE Planning Committee Co-chair

2. Vendor Workshop April 8-9, 2002 2 IHE Mission  IHE is an initiative promoting and supporting the integration of systems in the healthcare enterprise.

3. Vendor Workshop April 8-9, 2002 3 IHE Integration Goals Improve the efficiency and effectiveness of clinical practice:  Improve Workflow  Improve Information Accuracy  Improve Information Availability  Enable Cross-System Functionality

4. Vendor Workshop April 8-9, 2002 4 IHE Annual Cycle  Identify several key healthcare workflows and integration problems  Research & select standards to specify a solution  Write, review and publish IHE Technical Framework  Hold workshops and support vendor implementation  Perform cross-testing at “Connectathon”  Demonstrate/Promote at tradeshows (RSNA/HIMSS)

5. Vendor Workshop April 8-9, 2002 5 Who Does What?  RSNA and HIMSS (Chris & Joyce):  Provide a neutral forum for working on the Big Picture  Involve users/professionals and recruit companies  Sponsor IHE and provide infrastructure/continuity  Organize demonstrations and public education  Mallinkrodt (Steve):  Manage the Connectathon process  Create and administer the MESA Test Tools  IHE Committees:  Identify and design solutions for integration problems  Vendors:  Implement profiles on products

6. Vendor Workshop April 8-9, 2002 6 IHE & DICOM / HL7 Standards are vital (HL7, DICOM, ICD, …)Standards are vital (HL7, DICOM, ICD, …) –They provide tools & technologies But Standards alone are insufficientBut Standards alone are insufficient –They are open to interpretation –There is room for optional variations –They avoid specifying how to apply them to particular real world scenarios

7. Vendor Workshop April 8-9, 2002 7 How is IHE related to Standards? Profiles are packagingProfiles are packaging IHE attacks real world radiology integration problemsIHE attacks real world radiology integration problems HL7 and DICOM provide dictionariesHL7 and DICOM provide dictionaries IHE defines a “phrasebook” that solves real world problems by assembling pieces provided by DICOM/HL7IHE defines a “phrasebook” that solves real world problems by assembling pieces provided by DICOM/HL7
