Title: Integrating the Healthcare Enterprise
1Integrating the Healthcare Enterprise
- IHE, beyond cardiology and radiology
- An interoperability strategy for the enterprise
Charles Parisot, GE Healthcare IHE IT
Infrastructure Co-chair
2Goals 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
3IHE drives healthcare standards based-integration
4A Proven Standards Adoption Process

User Site
- IHE Integration Profiles at the heart of IHE
- Detailed selection of standards and options each
solving a specific integration problem - A growing set of effective provider/vendor agreed
solutions - Vendors can implement with ROI
- Providers can deploy with stability
5IHE 2004 achievements and expanding scope
Over 80 vendors involved world-wide, 4 Technical
Frameworks 31 Integration Profiles, Testing at
yearly Connectathons, Demonstrations at major
exhibitions world-wide
Provider-Vendor cooperation to accelerate
standards adoption
6IHE Deliverables
- Venues for discussion between users and vendors
- Common vocabulary/ view of the world based on
- Standard information models (HL7, DICOM, etc.)
- Coded information and their meaning
- Technical Framework An Implementation Guide
- ACTORS in roles performing TRANSACTIONS to
accomplish Specific Processes - Together they form INTEGRATION PROFILES
- Connectathon Cross-vendor testing opportunity.
- Public Demonstrations / Education/ Publications
- Marketing Tools for compliant products
- Connectathon results published
- Products claim conformance with Integration
Statement
7What IHE is NOT!
- A standards development organization
- Uses established standards (HL7, DICOM, 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 endadoption
- Backed up by documentation, tools, testing, and
publication of information
8IHE A stepwise approach
9Key IHE Concepts
- Generalized Systems -gt Actors
- Interactions between Actors -gt Transactions
- Problem/Solution Scenarios -gt Integration
Profiles - 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)

17Introduction EHR Cross-Enterprise Document
Sharing
First step towards the longitudinal dimension of
the EHR Focus Support document sharing
between EHRs in different care settings and
organizations
18Typically, a patient goes through a sequence of
encounters in different Care Settings
Long Term Care
Acute Care (Inpatient)
Other Specialized Care(incl. Diagnostics
Services)
GPs and Clinics (Ambulatory)
Continuity of Care Patient Longitudinal Record
19Finding the records of a patient-Manual tedious
The challenge Finding and accessing
easily documents from other care providers

22XDS Value Proposition
- Foundation for Health IT Infrastructures Shared
Electronic Health Record, in a community, region,
etc. - Effective means to contribute and access clinical
documents across health enterprises. - Scalable sharing of documents between private
physicians, clinics, long term care, pharmacy,
acute care with different clinical IT systems. - Easy access Care providers are offered means to
query and retrieve clinical documents of interest.
23XDS - Value Proposition
- Distributed Each Care delivery organization
publishes clinical information for others.
Actual documents may remain in the source EHR-CR. - Cross-Enterprise A Registry provides an index
for published information to authorized care
delivery organizations belonging to the same
clinical affinity domain (e.g. an LHII). - Document Centric Published clinical data is
organized into clinical documents. using
agreed standard document types (HL7-CDA,
ASTM-CCR, PDF, DICOM, etc.). - Document Content Neutral Document content is
processed only by source and consumer IT systems. - Standardized Registry Attributes to ensure
deterministic document searches.
24XDS Conclusion
- Foundation for EHR Health IT Infrastructures
- Effective contribution and access to shared
documents across all types of health enterprises - Scalable, Flexible and Easy access
- XDS to be one of the major highlights of 2005
Annual HIMSS Conference Exhibition. Dallas,
Tex., Feb. 13-17 - used as a foundation for an on-site demonstration
of interoperability in support of a National
Health Information Networks. - Attendees at the conference will be able to
create and share their own health records across
vendor booths as well as in the ambulatory and
acute care settings on the conference exhibit
floor.
25How real is XDS ?
- Specification work since Nov 2003
- Under Public Comments June-July 2004
- 600 constructive comments received,
- Stable specification IHE TF Aug 15th, 2004
- IHE Connectathon January 2005 (USA)
