INTEGRATING THE HEALTHCARE ENTERPISESolving Interoperability Challenges with IHE Elliot Sloane, PhD, CCE, FHIMSS Drexel University
IETF IHTSDO Interoperability: Major Cause of Health IT project failures? Base Standards We dread “standards” because there are SO many to choose from! eHealth Projects Health Interop. Standards: Ignore & Face Consequences 2
Standards: Necessary…Not Sufficient • Standards are • Foundational - to interoperability and communications • Broad - varying interpretations and implementations • Narrow - may not consider relationships between standards domains • Plentiful - often redundant or disjointed • Focused - standards implementation guides focus only on a single standard IHE provides a standard process for implementing multiple standards
IETF IHTSDO Interoperability: From a problem to a solution Profile Development Base Standards eHealth Projects Project Specific Extensions Profiling: Constraining “optionality” 4
IHE: Connects Standards to Care • Healthcare professionals work with industry • Coordinate implementation of standards to meet clinical and administrative needs • Clinicians and HIT professionals identify the key interoperability problems they face • Providers and industry work together to develop and make available standards-based solutions • Implementers follow common guidelines in purchasing and integrating effective systems IHE: A forum for agreeing on how to implement standards and processes for making it happen
IHE: A Framework for Interoperability A common framework for harmonizing and implementing multiple standards Application-to-application System-to-system Setting-to-setting Enables seamless health information movement within and between enterprises, regions, nations Promotes unbiased selection and coordinated use of established healthcare and IT standards to address specific clinical needs
Testing at Connectathons IHE Demonstrations Develop technical specifications Products with IHE Identify available standards (e.g. HL7, DICOM, IETF, OASIS) Timely access to information Document Use Case Requirements Easy to integrate products Standards Adoption Process
Stakeholder Benefits • Healthcare providers and health authorities • Improved workflows • Information whenever and wherever needed • Reduced implementation costs • Vendors • Align product interoperability with industry consensus • Decreased cost and complexity of interface installation and management • Focus competition on functionality/service not information transport • SDOs • Rapid feedback to adjust standards to real-world • Establishment of critical mass and widespread adoption

IHTSDO Use of IHE profiles in eHealth project Key health systems objectives Profiles for Use Case A Content & Terms • Patient summary • Lab Report • Imaging Info Exchange • ECG Report • . . . Use cases Interop-erability Tests Services Health Solution IHE profiles • Patient Demographics • X Document sharing • Health Provider Directory • . . . Standards Security and Privacy • Consent management • Audit Trail • . . .
Robust Interoperability Procurement System B System A 3 1 eHealth Network 2 System C A Profile specifies (by references to standards) what is exchanged “on the wire” between “abstract systems” called actors (e.g. 1,2,3) For each systems procured: 1 - Specify the Profile/Actors to be supported (avoids pages of detailed specs) 2 - Ask for the IHE Integration Statement (declares Profile/Actors supported) 3 – Ask for a declaration that the Actor/Profile implemented has been tested at an IHE Connectathon (check on the IHE Product Registry). 4 – Place contractual commitments to fix non-compliance to IHE Profiles claimed
eHealth and Interoperability: • Profiles for National Regional eHealth • Profiles for Intra Hospital Integration
IHE Profiles Spécifications Go to: www.ihe.net/Technical_framework Examples: • For Sharing and Accessing Health Records • E.g. IT Infrastructure Technical Framework (XDS.b) • For Patient Identification • E.g. IT Infrastructure Technical Framework (PIX, PDQ) • For Patient Care Coordination: medical summary • E.g. Patient Care Coordination Technical framework (XDS-MS) • For Sharing Radiology Reports and Images • E.g. Radiology Technical framework (XDS-I) • For Sharing Laboratory Reports/Tests • E.g. Laboratory Technical framework (XD*-Lab)

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 (health records). Complements to interactive workflow or dynamic access to data.
