Outline • IHE Process Overview • IHE for IT Infrastructure • IHE for Laboratory • IHE for Radiology • IHE Cardiology established first output expected for end of 2004
IHE Process Overview IHE introduces a novel process to accelerate the adoption and to facilitate use of standards in healthcare
IHE Mission Bring together stakeholders to implement standards for communicating clinical and operational data safely and efficiently throughout the healthcare enterprise
IHE Vision To provide relevant patient information at the point of care to support caregiver decision-making and optimal patient care
What is IHE? • A joint initiative to improve systems integration • Process for coordinated adoption of standards • Clinicians/IT staff define needs • Vendors develop solutions—Technical Framework • Professional societies supervise documentation, testing and demonstration/promotion
Goals of IHE • Speed up the rate and quality of integration in healthcare environments • Foster communication among vendors • Prove that integration is attainable based on standards • Improve the efficiency and effectiveness of clinical practice
What IHE is NOT! • A standards development organization • Uses established standards (HL7, DICOM, RFCs, others) to address specific clinical needs • Activity complementary to SDOs, formal relationship with HL7 and DICOM. • Simply a demonstration project • Demos only one means to the end—adoption • Backed up by documentation, tools, testing, and publication of information
IHE Participants • Societies Representing Healthcare Segments • ( Radiology, Lab, IT Professional Societies… ) • Users • ( Clinicians, Medical Staff, Administrators, CIOs, … ) • Information Systems Vendors • Clinical Systems and Device Vendors • Standards Development Organizations (SDOs) • HL7 • DICOM • Others …
Benefits to IHE Participants • Clinicians • Improved workflow • Information when and where needed • Fewer opportunities for errors • Fewer tedious tasks/repeated work • Administrators • Improved efficiency • Best of breed opportunities • Decreased cost and complexity of interface deployment and management
Benefits to IHE Participants • Vendors • Decreased cost and complexity of interface installation and management • Validation of integration at Connectathon • Focus competition on functionality/service space not information transport space • SDOs • Rapid feedback to adjust standards to real-world • Establishment of critical mass and widespread adoption

Key IHE Concepts • Generalized Systems -> Actors • Interactions between Actors -> Transactions • Problem/Solution Scenarios -> IntegrationProfiles • For each Integration Profile: • the context is described (which real-world problem) • the actors are defined (what systems are involved) • the transactions are defined (what must they do)
Actors • Represent a set of roles and responsibilities performed by a system • A real-world system may support several IHE Actors Examples: • Order Placer • Order Filler • Patient Identifier Cross-Referencing Mgr • Laboratory Automation • Report Creator
Transactions • Unambiguously defines how actors communicate • Using existing standards such as HL7 or DICOM to accomplish a specific task. Examples: • Procedure Scheduled • ADT Update • Retrieve Document for Display
Integration Profiles IHE Integration Profiles define a collection of real world functionality and group together the necessary Actors and Transactions to make it work. Examples: • Enterprise User Authentication • Retrieve Information for Display • Laboratory Scheduled Workflow • Patient Information Reconciliation

New at HIMSS in 2004 • In 2002 and 2003, IHE and HL7 have held separate demonstration • HL7 demos were « throw away » • IHE demos were « radiology centric » • IHE is now in Healthcare IT - 5 new profiles to be showcased at HIMSS 2004 • HL7 and IHE have decided this year to combine their demos and convey a 2 tier message: • HL7 broad in scope but leaves choices for interoperability • IHE Profiles are narrow in scope but high interoperability
HL7-IHE Interoperability demo • Demo scenario integrates 3 components: • - IHE IT Integration Profiles, and selected domain specific Profiles (e.g. Radiology). • - HL7 standard functions • - HL7 draft standard functions • Demo highlights how each component feeds into other and contributes to successful driving of standards in healthcare solutions.
HL7-IHE Interoperability demo • Live technology & product interoperability demonstration • At the center of the commercial exhibit floor at HIMSS, February 2004 • Promoted by HIMSS-signage show-wide.

The IHE Technical Approach • Identify the transactions required to integrate a specific information flow between several information systems/devices • For each transaction, select a single standard (e.g.HL7 messages, RFC) for use in implementing the transaction • Specify in detail the use of the standard in implementing the transaction
