									       IHE IT Infrastructure Domain
                   Update




Karen Witting – IBM
IT Infrastructure Technical Committee co-chair
          IHE - Connecting standards to care

• Care providers work with vendors to
  coordinate the implementation of
  standards to meet their needs
  – Care providers identify the key interoperability
    problems they face
  – Drive industry to develop and make available
    standards-based solutions
  – Implementers follow common guidelines in
    purchasing and integrating systems that
    deliver these solutions
                  IT Infrastructure Domain (ITI)



• Supports profiles which supply necessary
  infrastructure for sharing healthcare information.

• IT Infrastructure domain began in 2003 and now
  has 18 profiles that it supports.

• Key ITI profiles demonstrated today:
   – Information Exchange: XDS, XDM, XDR, XDS-SD, RFD
   – Security: ATNA, CT
   – Identity Management: PIX, PDQ (HL7 V2 & V3)
An Infrastructure Interoperability Component Is…



• An infrastructure Interoperability component…
   – Represents a common IT function or service that is
     used as a building block for a variety of use cases
   – May be imbedded in an application, but is often
     deployed as a shared resource within a RHIO or
     Health Information Exchange
   – Is a necessary ingredient, but is rarely visible to the
     end user

     requirements of an external system. Supports form retrieval, form
     completion, form submission.
   – Applicable to usecases: drug trials, public health reporting,
     pharmaco-vigilance, cardiology research,
                                               2003-2005

 Health Information Exchanges Interoperability: Cross-enterprise Document Sharing



• Cross-Enterprise Document Sharing simplifies clinical data
  management by defining interoperable infrastructure.
  Transparency = Ease of Evolution
• Patients have guaranteed portability and providers may share
  information without concerns of aggregation errors.
  Digital Documents = Patients and providers empowerment
• Supports both centralized and decentralized repository architectures.
  Ease of federation nationally. Flexible privacy, Flexibility of
  configurations
• Addresses the need for a longitudinal healthcare data and its intend
  is for support of archival data. It does not address workflow or
  dynamic data access.
• Workflows addressed in a second step in a much simpler manner.
  Point-to-Point messages best suited for workflows mgt

                             HL7, ASTM CCR

          Electronic Business            Internet Standards
               Standards                     HTML, HTTP,
          ebXML Registry, SOAP,            ISO, PDF, JPEG …
             Web Services …
• Implemented world-wide by more than 30 vendors/open source.
  Final text published December 2006.
• Adopted in several national & regional projects (Italy, France,
  Canada, Austria, USA, etc.)
• IHE XDS: 42,300 “Google” references (Feb’ 07)
                 Why is IHE-XDS a breakthrough ?

• It based on an International Standards; ebXML registry: OASIS and
  ISO standard, Web Service/Soap/XML.
• Sharing of digital documents as “attested by the source”, meets the
  most urgent needs. A proven healthcare community data-sharing
  paradigm (Message feeding a central web server hinders use of EHRs).
• Efficient to support all types of Health IT Systems (IDNs, Hospitals,
  Ambulatory, Pharmacy, Diagnostics Centers, etc.) and all types of
  information (summaries, meds, images, lab reports, ECGs, etc.),
  structured and unstructured.
• Meets both the needs of point-to-point push communication and on-
  demand pull in a variety of centralized or distributed architectures.
Offer a consistent, standards-based and functional
record sharing for EHRs, PHRs & other IT Systems
