Goal of IHE
It’s an initiative promoting and supporting the integration of systems in the healthcare enterprise
Integration Goal: Improve the efficiency and effectiveness of clinical practice by: Improved Information Flow Advanced Multi-System Functions With minimal “integration project pain”

IHE process
• Users and vendors work together to identify and design solutions for integration problems
• Intensive process with annual cycles:– Identify key workflows and integration problems– Research & select standards to specify a solution– Write, review and publish Technical Framework– Perform cross-testing at “Connectathon”– Demonstrations at tradeshows:
RSNA/HIMSS, and also JFR, DRK, JMCP

Role of standards in IHE• IHE attacks real world radiology integration
problems
• Standards such as HL7 and DICOM provide dictionaries
• IHE defines a “phrasebook” that solves real world problems by assembling pieces provided by DICOM/HL7
• IHE is also a way to promote and advance the implementaion of standards

IHE Integration Profiles
• Integration solution for real-world integration problems
• Set of related transactions among systems
• Allow buyers to focus on high-level integration, cornerstone for defining requirements in RFP’s
• Implementation is defined by the IHE Technical Framework
