Title: IHE, Interoperability for Regional Health Information Organizations


1
IHE, Interoperability for Regional Health
Information Organizations
  • Charles Parisot, GE Healthcare
  • Mike Henderson, Eastern Informatics
  • IHE IT Technical Committee Co-Chairs

2
  • Providers and Vendors
  • Working Together to Deliver
  • Interoperable Health Information Systems
  • In the Enterprise
  • and Across Care Settings

3
State of the Union Addresses
  • By computerizing health records, we can avoid
    dangerous medical mistakes, reduce costs and
    improve care.
  • President George W. Bush
  • January 20, 2004

4
And the beat goes on..
  • . most Americans will have electronic health
    records within the next 10 years

President George W. Bush April 26, 2004 In a
public address to the American Association of
Community Colleges, the President outlined a plan
whose goal is to assure better delivery of
healthcare in the United States.
5
Framework for Strategic Action
  • President Bushs April 27th executive order
    called for the creation of the Office of the
    National Coordinator of Health Information
    Technology (ONCHIT). A report was required
    within 90 days of office creation.
  • The Framework for Strategic Action was released
    by Department of Health and Human Services
    Secretary Tommy Thompson and newly appointed
    National Coordinator of Health Information
    Technology, David Brailer, MD, at the NHII Summit
    in July, 2004.

6
Four Major Goals
  • Inform Clinical Practice
  • Incentivize EHR adoption
  • Reduce risk of EHR investment
  • Promote EHR diffusion in rural underserved
  • Interconnect Clinicians
  • Foster regional collaborations
  • Develop a national health information network
  • Coordinate federal health information systems

7
Four Major Goals
Thousands of EHRs to interconnect, Through a
thin National Health Information Network. Make
connectivity open, consistent, step-wise and
evolutionary ! IHE can accelerate and simplify
the process. See 13 Organization Collaborative

CoverLetter1.pdf
  • Personalize Care
  • Encourage use of PHRs
  • Enhance informed consumer choice
  • Promote use of telehealth systems
  • Improve Population Health
  • Unify public health surveillance architectures
  • Streamline quality and health status monitoring
  • Accelerate discovery and dissemination

8
Standards Alone Are Not Enough
  • Managing the domain boundaries with mapping of
    information flow across boundaries
  • Standards offer generality, ambiguity and
    alternatives.
  • Vendor proprietary interests
  • Complexity!!

We need standards for how to implement standards!
9
Connecting Standards to Care
  • Care providers must work with vendors to
    coordinate the implementation of standards to
    meet their needs
  • Care providers need to identify the key
    interoperability problems they face
  • Drive industry to develop and make available
    standards-based solutions
  • Implementers need to follow common guidelines in
    purchasing and integrating systems that deliver
    these solutions

What is the effective way to establish those
standards for how to implement standards ?

What is Integrating the
Healthcare Enterprise ?
  • IHE provides a common framework for passing
    health information seamlessly
  • within the healthcare enterprise
  • across multiple healthcare enterprises
  • for local, regional national health information
    networks.
  • IHE is sponsored by healthcare professional
    associations (ACC, HIMSS, RSNA, etc.).
  • IHE drives standards adoption to address specific
    clinical needs.

12
IHE Maturity and Acceptance
  • More than 100 healthcare vendors worldwide have
    contributed to IHE and the delivery of
    ready-to-integrate products to benefit healthcare
    enterprises of all sizes.
  • IT professionals clinicians appreciate IHEs
    positive impact now expanded to address
  • radiology, cardiology, laboratory
  • enterprise healthcare IT infrastructures
  • cross-enterprise healthcare IT infrastructures

13
Understanding the IHE Initiative
  • IHE has a clear focus
  • IHE is a healthcare domain-based initiative
  • IHE creates synergies for interoperability
    testing across domains
  • IHE addresses the standards adoption process
  • IHE is both regional and multi-national
  • IHE is both user-led and vendor-driven

14
A Proven Standards Adoption Process
IHETechnicalFramework
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

15
Achievements and expanding scope
Over 100 vendors involved world-wide, 4 Technical
Frameworks 27 Integration Profiles, Testing at
yearly Connectathons, Demonstrations at major
exhibitions world-wide
To claim compliance to IHE Integration Profiles
vendors shall publish for each product an IHE
Integration Statement.
16
IHE Survey Results
  • 92 of respondents were aware of IHE
  • Potential benefits of IHE ?
  • Improved clinical workflow access of data
    63
  • Benefits of IHE products ?
  • Reduce deployment costs

Sharing
Internet Standards HTML, HTTP,ISO, PDF, JPEG,

Electronic BusinessStandards ebXML Registry,

HealthcareContent Standards HL7 CDA, CEN
EHRcomHL7, ASTM CCRDICOM, etc.
Marriage of healthcare standards facilitates
implementation and leverages complementary
technologies (e.g. security privacy).

IHE Profiles for RHIOs What is
available and what will be added in 2005
25
Local 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
  • Audit Trail and Node Authentication (ATNA) and
    Consistent Time (CT)
  • Patient Id Cross-referencing (PIX)
  • Patient Demographics Query (PDQ)
  • In 2005, IHE plans to finish base set of
    integration profiles to build regional health
    networks and interoperable EHRs
  • Security Identity Management Accountability
  • Content Profiles DICOM, HL7-CDA/CCR, HL7-Lab,
    PDF.
  • Notification of Document Availability (with XDS
    document reference)

26
IHE 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.
  • RHIOs technical architects needs direct IHE
    involvement. Policies easier to establish when
    based on solid IHE Technical Framework, but are
    beyond IHEs scope. They remains RHIOs
    responsibility.
