Integrating the Healthcare Enterprise Achieving Real-World Interoperability

What is IHE about?  IHE is an initiative promoting and supporting the integration of systems in the healthcare enterprise.  Goal: Improve the efficiency and effectiveness of clinical practice by:  Improved Information Flow  Advanced Multi-System Functions

How is IHE related to Standards? Standards provide tools & technologiesStandards provide tools & technologies –HL7 and DICOM provide dictionaries IHE specifies how to apply them to real world scenarios & integration problemsIHE specifies how to apply them to real world scenarios & integration problems –IHE defines a “phrasebook”

What Does IHE Do? Users and vendors work together to identify and design solutions for integration problemsUsers and vendors work together to identify and design solutions for integration problems Intensive process with annual cycles:Intensive process with annual cycles: –Identify key healthcare workflows and integration problems –Research & select standards to specify a solution –Write, review and publish IHE Technical Framework –Perform cross-testing at “Connectathon” –Demonstrations at tradeshows (HIMSS/RSNA)

SNM, Vendor & IHE Cooperation Integrate NM into IHE demosIntegrate NM into IHE demos Use established IHE “network” to help distribute and get support for all parts of NM DICOM standardUse established IHE “network” to help distribute and get support for all parts of NM DICOM standard Work with PACS vendors on display issues unique to NMWork with PACS vendors on display issues unique to NM
