11Local Regional RHIOs Infrastructure and
Interoperability
- Cross-Enterprise Document Sharing (XDS) minimizes
clinical data management by the infrastructure.
Transparency Ease of Evolution - XDS works with other IHE Integration Profiles
patient Id mgt, security, etc. Flexibility of
RHIO configuration - With introduction of new Integration Profiles,
IHE ready to build regional health networks
linking interoperable EHRs. Major milestone for
2006 RHIO projects - Goal is to offer a consistent, standards-based
and functional for EHRs and other ancillary
systems.

23IHE RHIOs Interoperability Partner
- IHE offers a solid technical foundation to
establish interoperability for RHIOs. - Standards-based, open, multi-vendor,
provider-led. - Yearly progress, validation testing built in,
backed by a proven process. Implementation by
many vendors. - IHE welcomes RHIOs technical architects active
involvement. - The IHE Technical Framework accelerates RHIOs
pilot development (e.g. XDS Affinity Domain). - This is being applied Norway, Italy, then
Canada, soon USA, France, ?

Audit Trail Node Authentication
Centralized privacy audit trail and node to node
authentication to create a secured domain.
32IHE Interoperability for RHIOs
- By starting with a secured document sharing
infrastructure, RHIOs have a a platform on which
to build clinical content (more structure coded
terminology, specialized content). - Solid SAML 2.0 authentication and document
digital signature (need a PKI). - Practical HL7 V3 approach with CDA-R2 and other
content (e.g. imaging, CCR, legacy, PDF, etc.). - Establishing a critical mass of products
implementations, both in clinical applications
and infrastructure for deployment in 2006. - An architecture that caters to various RHIOs
architectures centralized, decentralized and
mixed (operational decision).
