2 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 Based on patient situation When they see fit (discharge, end of encounter, etc.) When they see fit (discharge, end of encounter, etc.) What information to share (pick relevant types of documents, and content elements). 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 their own EMR (if they have one), or through a shared portal otherwise. through a shared portal otherwise.  When accessing patient info: Find quickly if relevant information is available or not (single query). 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) 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). Among those of interest, chose to import in whole or part in its own EMR Chart (responsibility).

3 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 node or IT system interfaced is strongly authenticated Each user shall be authenticated on the edge system (where context is best known) Each user shall be authenticated on the edge system (where context is best known) All traffic trough the infrastructure is encrypted All traffic trough the infrastructure is encrypted  Shared Document Registry does not contain patient clinical data only generic information (minimum metadata + repository reference)  Patient consent needs multiple choices or levels Unless opt-in, no data about a specific patient may be shared Unless opt-in, no data about a specific patient may be shared Several data sharing policies offered to the patient consent Several data sharing policies offered to the patient consent Each shared document is assigned to specific policies (or not shared) at encounter time. Each shared document is assigned to specific policies (or not shared) at encounter time. Healthcare providers may only access documents compatible with their role. Healthcare providers may only access documents compatible with their role.

4 IHE - Connecting standards to care Care providers and IT professionals 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

5 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

8 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.

9 Cross-Enterprise Document Sharing (XDS) Standards Used Healthcare Content Standards HL7 CDA, CEN EHRcom HL7, ASTM CCR DICOM … Internet Standards HTML, HTTP, ISO, PDF, JPEG … Electronic Business Standards ebXML Registry, SOAP, Web Services … Implemented world-wide by more than 50 vendors/open source. Final text published December Adopted in several national & regional projects (Italy, France, Canada, Austria, USA, Japan, Netherlands, Sweden, etc.) IHE XDS: 42,300 “Google” references (Feb’ 07)

10 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 push communication by info sources 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

11 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.
