IHE, Integrating the Healthcare Enterprise, creates solutions for interoperability problems in healthcare by developing standards based interface specifications. Healthcare ICT products that have implemented the IHE specifications make the integration efforts for an eHealth solution much easier. Conformity assessment in the deployment process towards an operational application portfolio is supported by a proven test methodology and Open Source test tools.

IHE Product Selection and Acceptance Testing

Streamlining Product Selection and Acceptance Testing v Effective and efficient performance of Business Use Cases are enabled by a connected set of administrative and clinical applications v Initial challenge: Ø  Selection of suppliers and systems Ø  Integrate systems, educate users, and start-up the operation v On-going challenge: Maintain the operational ICT Application portfolio Ø  New releases Ø  New systems Ø  New connections Ø  New functionality v IHE profiles for exchange, content, terminology, workflow, security and privacy enable this in a multi-vendor setting. v Supported by the IHE Test Tools and Procedures in the Conformance Assessment continuum.

Your Contribution to a Sustainable eHealth Interoperability Ecosystem IHE Profiles Include IHE Test Tools creation in eHealth programs, and contribute to Open Source pool of IHE Test Tools. Test Tools Foster the creation new IHE Profiles for emerging interoperability challenges Healthcare providers eHealth Suppliers Include IHE profiles in eHealth solution architecture and RFPs. Timely release products to market with IHE Integration Statements

Value from applying IHE v Suppliers of eHealth systems Ø  Reduce cost for development and maintenance of product communication interfaces (reduced diversity, Open Source tool box) Ø  Access to bigger market (reduced market entry threshold) v Users of eHealth systems Ø  Freedom to choose products with best-fit functionality (competition) v ICT Department Ø  Reduce integration cost (reduced diversity, reduced complexity, Open Source tool box) Ø  Reduce on-going maintenance cost for the ICT Application portfolio (reduced diversity, Open Source tool box)
