Didi Davis, HIMSS Senior Director, Informatics/IHE International Introduction to Integrating the Healthcare Enterprise (IHE) and IHEs contribution to standards harmonization for the Nationwide Health Information Network
2 What is Standards Harmonization? Healthcare is a complex multi-specialty multi-stakeholder system. Multiple standard development organizations are necessary.Healthcare is a complex multi-specialty multi-stakeholder system. Multiple standard development organizations are necessary. Challenge is to achieve interoperability while implementing multiple standards to meet a broad range of information exchange needs:Challenge is to achieve interoperability while implementing multiple standards to meet a broad range of information exchange needs: –Application-to-application –System-to-system –Setting-to-setting Coordinate adoption of standards to meet clinical and administrative Use CasesCoordinate adoption of standards to meet clinical and administrative Use Cases –Identify the key interoperability problems they face –Providers and industry work together to develop and make available standards-based solution
Standards: Necessary…Not Sufficient Standards areStandards are –Foundational - 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 typically focus on a single standard Need a standard process for implementing multiple standards
What is Integrating the Healthcare Enterprise? A 9-year public-private initiative Driven by end-users, IHE improves patient care by harmonizing electronic health information exchange Enables approved standards to seamlessly pass health information among care providers on a local, regional and national level IHE Frameworks are freely available to all The IHE Global Standards Adoption process as approved by the International Standards Organization (ISO) as a Technical Report in August 2007
How does IHE work? Clinicians and IT professionals identify key clinical and business workflow problemsClinicians and IT professionals identify key clinical and business workflow problems Clinicians, IT professionals, consultants, and vendors jointly solve those problems by standardizing the way existing standards are implemented in HIT productsClinicians, IT professionals, consultants, and vendors jointly solve those problems by standardizing the way existing standards are implemented in HIT products IT professionals follow the IHE guidelines in purchasing and integrating effective systemsIT professionals follow the IHE guidelines in purchasing and integrating effective systems
Integrating the Healthcare Enterprise Achieving Interoperability through Implementation of Standards 1997: Founded in Radiology (RSNA) and IT (HIMSS) Many professional societies (stakeholder representation)Many professional societies (stakeholder representation) –American Academy of Ophthalmology (AAO) –American College of Cardiology (ACC) –American College of Physicians (ACP) –American College of Clinical Engineering (ACCE) –American College of Emergency Physicians (ACEP) –American Society for Therapeutic Radiation Oncology (ASTRO) –GMSIH (IT France), JAHIS (IT Japan), SFIL (laboratory) –Healthcare Information Management Systems Society (HIMSS) –Radiological Society of North America (RSNA) –And many more….

The Community is the Hub that Drives Interoperability AHIC, chaired by HHS Secretary provides strategic coordination. CCHIT focuses on developing a mechanism for certification of health care IT products HITSP brings together all relevant stakeholders to identify & harmonize appropriate standards HISPC addresses variations in business policy and state law that affect privacy and security NHIN is focused on interoperability pilots and implementation Healthcare Information Technology Standards Panel (HITSP) Nationwide Health Information Network (NHIN) Architecture Projects The Health Information Security and Privacy Collaboration (HISPC) The Certification Commission for Healthcare Information Technology (CCHIT) American Health Information Community (AHIC)
Standards Harmonization HITSP (Healthcare Information Standards Panel)
US Federal Initiative for Health IT and Nationwide Health Information Network The U.S. healthcare system is managed both at the federal level and the state-level. Over 200 Health Information Exchange projects in the U.S. at the state level or regional communities within the states. At the federal level, HHS has set-up a policy-level setting board (AHIC), a coordination office (ONC) and 4 supporting initiatives for standards harmonization, certification, privacy and implementation prototyping. IHE-USA has been engaged in the organization of one of these supporting initiatives: HITSP. IHE and its sponsors (e.g. HIMSS, RSNA, ACCE, etc.) and participants contribute to those initiatives.
HITSP Delivers Interoperability Specs to AHIC The Healthcare Information Technology Standards Panel (HITSP) has addressed 7 business use cases for interoperability. HITSP has nearly 400 member organizations representing all U.S. stakeholders including Standards Development Organizations (incl. X12, DICOM, HL7, etc.). HITSP, through its standards-based interoperability specifications, is leveraging standard-based implementation guides such as those from Integrating the Healthcare Enterprise (IHE). The IHE Connectathon and the HIMSS Interoperability Showcase play a visible role demonstrating the HITSP/IHE synergy.

Requirements for an open RHIO/HIE(1) Bring trust and ease of use for healthcare professionals: –Care delivery organizations choose information to share: Based on patient situation When they see fit (discharge, end of encounter, etc.) What information to share (pick relevant types of documents, and content elements). –Care delivery organizations access patient information through: their own EMR (if they have one), or through a shared portal otherwise. –When accessing patient info: Find quickly if relevant information is available or not (single query). May select among relevant documents, which ones to see (may be done in background) Among those of interest, chose to import in whole or part in its own EMR Chart (responsibility).
Requirements for an open RHIO/HIE(2) Bring trust and privacy to patients: –Only authorized organizations and authenticated healthcare providers may transact in the HIE: Each node or IT system interfaced is strongly authenticated Each user shall be authenticated on the edge system (where context is best known) All traffic trough the infrastructure is encrypted –Patient consent needs multiple choices or levels Unless opt-in, no data about a specific patient may be shared Several data sharing policies offered to the patient consent Each shared document is assigned to specific policies (or not shared) at encounter time. Healthcare providers may only access documents compatible with their role. –Shared Document Registry does not contain patient clinical data only generic information (minimum metadata + repository reference)
Categories of Healthcare Communication Services Security Document Sharing Patient and Provider ID Mgt Dynamic Information Access Workflow Management Source persisted and attested health records Specific info snapshot provided on demand 2 or more entities synchronize a task e.g. access to last 6 months historical labs and encounter summaries e.g. order a lab test, track status and receive results e.g. get a current list of allergies or med list from a source Hospitals HIEs and RHIOs
What is IHE IT Infrastructure? IHE IT Infrastructure domain produces... –Profiles that serve the purposes of clinical workflows, regardless of IHE clinical domain Examples: Security, Records Storage, Patient Identifiers –Basic implementation-specification foundations to be extended by other IHE clinical domains Examples: Retrieve Forms for Data Capture; Cross-Enterprise Document Sharing –White Papers for current work items Examples: HIE Security and Privacy; Health Data Re-use Infrastructure; Risk Management

IHE-XDS Infrastructure Components Audit Record Repository (ATNA) – Receive audit records from other actors and securely store for audit purposes. ATNA also authenticates peer-nodes and encrypt communications. Time Server (CT) – Provides consistent definition of date/time enabling time synchronization across multiple systems. Enables events associated with patients to be sorted reliably in chronological order. Document Registry (XDS) – Queryable index of metadata and references to all documents shared within a connected community (XDS Affinity Domain) Document Repository (XDS) – Supports storage and retrieval of clinical information (as documents). May be centralized or distributed. Patient Identifier Cross Reference Manager (PIX) – Reconciles information on patients from multiple domains to a single, cross referenced set of ids for each given patient. Patient Demographics Supplier (PDQ) – Returns demographic information and identifiers for patients based on specified demographic criteria.
