  1. IT Infrastructure 2007-2008 Plans Karen Witting – IBM IT Infrastructure Technical Committee co-chair

  2. IHE IT Infrastructure – Schedule for 2007 • Development Schedule • Planning Committee decision: January 2007 • Issue Public Comment version: June 2007 • Public Comment Due: July 2007 • Issue Trial Implementation version: August 2007 • IHE Connectathon: January 2008 • HIMSS Demo: February 2008 • Face-to-face ITI Technical committee • to prepare 2007 work items • held in RSNA headquarters Chicago • March 13-15 2007 Resolve significant technical issues • May 14-18 2007 Prepare public comment version • July 23-27 2007 Prepare trial implementation version

  3. IHE IT Infrastructure – Plan for 2007 • New Supplements For 2007 • Web Services for XDS – Roberto Ruggeri • Cross Enterprise User Authentication (XUA) – John Moehrke • Cross Community Access (XCA) – Karen Witting • Significant updates to existing last years profiles • PIX/PDQ HL7 V3 transactions updated to support latest V3 specification • RFD updated for latest level of XForms specification • White Papers for 2007 • Configuration Management • Security Risk Management • Web Services Roadmap • Aggregate Data • Meeting Privacy Principles using IHE Profiles • Change Proposal (CP) work for all profiles

  4. Web Services for XDSValue Proposition • Bring XDS in line with current Web Services standards • Builds on the WS adoption of XDS Stored Query. • Easier to develop and manage • Align use of ebXML Reg/Rep standard to version 3.0 • Stored Query transaction introduced in 2006 is based on 3.0 • Original transactions are based on ebXML Reg/Rep 2.1 • Lay the foundation for security, federation, reliable messaging work (XUA, XC…)

  5. Web Services for XDSTechnical Solution • Defines optional Web Services based versions of the existing transactions: • Updated Provide & Register on-line transaction based on SOAP/MTOM • New Document Retrieve using SOAP/MTOM • Updates Web Services specification to use SOAP 1.2 • Updates metadata format to use ebXML Reg/Rep 3.0 for Provide & Register, Register, and Retrieve • New WSDL contracts for all the new Web Services XDS transactions • Integrates WS for PIX/PDQ HL7 v3 for the Patient Identity Feed

  6. Cross-Enterprise User AuthenticationValue Proposition • Extend User Identity to Affinity Domain • Users include Providers, Patients, Clerical, etc • Must supports cross-enterprise transactions, can be used inside enterprise • Distributed or Centralized. • Provide information necessary so that receiving actors can make Access Control decisions • Does not include Access Control mechanism • Provide information necessary so that receiving actors can produce detailed and accurate Security Audit Trail

  7. Cross-Enterprise User AuthenticationTechnical Solution • Initial scope to XDS-Stored Query and XDS-Retrieve (WS) • Relies on Web Services profiling work in progress • Leverage WS-I Basic Security Profile 1.1 • Use SAML Assertions • Leverage IHE PWP Profile • Update PWP to include user attributes needed • Define grouping behavior with EUA and ATNA

  8. Cross Community AccessValue Proposition • Sharing of documents beyond the XDS Affinity Domain (community) boundary. • Part of a larger vision for regional and national sharing – 2006 whitepaper on Cross Community Information Exchange • Cross Community Access (2007) • Cross Community Location (2008) • Scoped to document sharing between XDS Affinity Domains. Future goal to define sharing with other types of communities.

Community Search Service National Network A Non-IHE National EHR CrossCommunity Bridge IHE Transactions (future) CrossCommunity Bridge Cross Community Bridge • National or Regional Networks not required to be IHE-based • Mapping to & from IHE Transactions performed by X-Community bridges • Mapping practical as most European projects use variants of structured document sharing CommunityLocator service IHE based Sub-Networks Non-IHE Sub-Net Integrated Delivery Network

  11. Cross Community AccessTechnical Solution • Cross Community Bridge • A new actor which supports all inter-community communications. Encapsulates in one actor all activities required to communicate outside the community. • Every community would have one cross community bridge which would interact with actors within the community and remote cross community bridges. • Cross Community Consumer • Initiator of a request for information beyond the community. • Technical Issues: • Need for asynchronous transactions in the cross community environment • Interaction with existing XDS actors • Reliable identification of the patient

  12. White Papers • Security Risk management • Cookbook for the security section of IHE profiles. Publish final text. • how to run a risk assessment for interoperability specifications (IHE Profiles). • Web Services Roadmap – June 2006 • Web Services standards are in rapid evolution and states of adoption. • Provide across IHE a solid stepwise and pragmatic plan for staged adoption. • Access to Aggregate Data – June 2006 • Requirements & standards evaluation for an infrastructure for surveillance/notification for quality mgt, public health and research. • Complementary to IHE-XDS working in both distributed and centralized repositories architectures. • Configuration Management – August 2006 • Establish the general principles of intra-enterprise and cross-enterprise systems configuration for interoperability • Requirements & standards evaluation for a configuration infrastructure • Meeting Privacy Principles using IHE Profiles • Shows how the IHE Profiles address data protection principles (e.g. OECD Data protection principles) when used in a proper policy environment.
