1 IHE IT Infrastructure Domain Update Karen Witting – IBM IT Infrastructure Planning Committee co- chair

2 IT Infrastructure Domain (ITI) Supports profiles which supply common infrastructure for sharing healthcare information. IT Infrastructure domain began in 2003 and now has 27 profiles that it supports. Key ITI profiles demonstrated today (and tested at Connectathon): – Information Exchange: XDS, XDM, XDR, XCA, XDS-SD, RFD, DSUB – Security: ATNA, CT, XUA, BPPC – Identity Management: PIX, PDQ (HL7 V2 & V3), HPD

3 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 Health Information Exchange – Is a necessary ingredient, but is rarely visible to the end user

4 ITI Strategic Focus Categories Patient and Provider Identity – support the management of patient, provider and healthcare organization identity including their localization. This includes the ability to look up, cross-reference, update, remove, merge, link and general management of identities. – PIX, PDQ, PAM, PWP, XCPD, HPD, PIX/PDQ HL7 v3 Health Record Sharing – support the ability to share patient specific healthcare information within and across enterprises. This includes the ability to submit, locate/list, push, pull and retrieve patient specific healthcare information. – XCA, XDM, XDR, XDS, XDS-SD, MPQ, RID Security and Privacy – support the ability to ensure that healthcare information is managed consistent with a reasonable set of security and privacy policies. – ATNA, BPPC, XUA, DSG, EUA Workflow Enablers – support standard sequences for performing workflow activities. – DRR, DSUB, NAV, PSA, RFD Support Management – support the ability to share information needed for interoperable healthcare management such as clinical coding, technical or IT management information – CT, SVS

5 Different Information Exchange Approaches Point –to- Point Health Information Sharing One to Many, Pull Known Partners Patient Association May Be Out-of-Band Document Content: Blind or Labelled EMPI Document Registry / Record Locator 1-n Document Repositories

6 Point-to-point Deployment Models Known partners, patient ID out-of-band, blind document Known partners, patient ID out-of-band, labelled document Known partners, linked patient, labelled document Secure … Direct Project w/o Document Metadata Option IHE Cross-Enterprise Document Exchange - Option (XDM- ) IHE Cross-Enterprise Reliable Exchange (XDR) w Patient ID Reconciliation (PIX/PDQ) IHE takes Direct to the next level Direct moving to the next level

7 Health Information Sharing Deployment Models Many potential partners, linked patient, labelled documents Centralized services (registry/EMPI) Nationwide Health Information Network Exchange / FHA CONNECT IHE Cross-Enterprise Document Sharing (XDS) IHE Cross-Enterprise Document Sharing (XDS) (On-Demand Document Option and Document Subscription / Notification (DSUB)) IHE Patient ID Cross-reference (PIX) and Patient Demographics Query (PDQ) IHE Patient ID Cross-reference (PIX) and Patient Demographics Query (PDQ) IHE Cross-Community Exchange (XCA) IHE Cross-Community Exchange (XCA) IHE Cross-community Patient Discovery (XCPD) IHE Cross-community Patient Discovery (XCPD) IHE takes Direct to the next level

8 XDS Metadata Direct Project Direct Project, Nationwide/Exchange and IHE Profiles Direct is aligned with XDM: recommends but does not require metadata Nationwide/Exchange is aligned with XCA and XDR XDR may be bridged into Direct Project with metadata option Nationwide/Exchange IHE XDM ( ) IHE XDR (Web Service) IHE XCA (cross-HIE) IHE XDS (Intra-HIE) Pt-to-Pt Push Share & Pull Option in Direct

13 IT Planning Committee Activities 2010 ITI Planning Committee – ITI Strategic Planning Definition of ITI Categories Development of Liaisons and Outreach plan – Selection of new work for 2011 review proposals and identify new work for each development cycle 2011 ITI Planning Committee – Preparation of Educational Material – development of reusable PPT decks on key ITI topics – Strategic Planning and Liaison Activity – build liaisons with other IHE committees – Selection of Trial Implementation Supplements to become Final Text Profiles – Selection of new work for 2012

14 ITI Technical Committee Activities 2010 ITI Technical Committee – Delivered new supplements for 2010 (next charts) – Delivered 2010 versions of Technical Framework and Supplements Processing of numerous Change Proposals (CPs) Integration of CPs into 2010 versions of documentation 2011 ITI Technical Committee – New Supplements/Handbook For 2011 (next charts) – Change Proposal processing – Delivery of 2011 updated version of Technical Framework and prior year Supplements

15 IHE ITI Completed Work for 2010 Healthcare Provider Directory (HPD) – Supports interoperable feed and query transactions for healthcare provider information – Supports individual and organizational providers – Transactions are based on LDAP and DSML Cross-Enterprise User Assertion - Attribute Extension (XUA++) – Extends XUA based on feedback on attributes – Adds attributes supporting Role-Based-Access Control, Consent/Authorization, Purpose of Use and general descriptive attributes XDS Metadata Update – Enables update and deletion of metadata in the XDS/XCA/XDR profiles SVS Extension – Update integrated directly into SVS supplement – Adds value set metadata and search capability in support of publication and distribution of value sets. On-Demand Documents – Supports sources of healthcare data which prefer to build most up-to-date document content at the time of retrieve, on-demand Delayed Document Assembly – Allows source systems to register the existence of stable document content but defer actually assembling the document content only if and when it is retrieved. This approach is adopted for efficiency reasons.

16 IHE ITI New Work for 2011 XDS Affinity Domain Patient Identifier Change Management (XPID) – Communication of link, unlink and merge events to XDS Document Registry Cross-Enterprise Document Workflow (XDW) – Tracking the steps of workflows to support care coordination and clinical pathways XCA Query and Retrieve – Combining XCA Query and XCA Retrieve transactions Direct Project Push use of XDS Metadata – Adjustment of XDS metadata requirements when used in XDR and XDM environments with minimal metadata knowledge Document Encryption – Standard mechanism for encrypting health documents Pseudonymisation and De-Identification in IHE Profiles (Handbook) – Providing guidelines to industry on the application of pseudonymisation
