3 July 2005Interoperability for Lab - IHE Canada3 Lab to Ambulatory EHR Interoperability Workflows Two primary workflows models are used around the world: –Contract to Lab model: the ambulatory physician is the lab customer and sends the patient or specimen to selected lab. –Collaborative Lab Model: the patient selects lab and follows physicians lab prescription. Both models exist is most countries but one of the two often is the most prevalent Workflow contains two time segments: –Electronic Order/Real-Time Result Communication: ordering physician, patient and laboratory. Completes when result delivered. –Access to Historical Results: Same patient but in later encounters need access to previous performed lab studies. Does IHE offers today the corresponding basic interoperability ?

9 July 2005Interoperability for Lab - IHE Canada9 Local & Regional RHIOs Infrastructure and Interoperability IHE has been focusing significant efforts on cross- enterprise health information sharing for the past three years We will provide an update on this work and some of the major accomplishments in this area that do benefit the access to laboratory results. Discuss what can be implemented today.

10 July 2005Interoperability for Lab - IHE Canada10 Selected IHE Integration Profiles for RHIOs What is available and is added in 2005 Consistent Time Coordinate time across networked systems Audit Trail & Node Authentication Centralized privacy audit trail and node to node authentication to create a secured domain. Patient Demographics Query Cross-Enterprise Document Sharing Registration, distribution and access across health enterprises of clinical documents forming a patient electronic health record Notification of Document Availability Notification of a remote provider/ health enterprise Lab Results Document Content Format of the Document Content and associated coded vocabulary For Display Document Format of the Document Content Imaging Information Sharing Format of the Document Content and associated coded vocabulary Medical Summary Document Content Format of the Document Content and associated coded vocabulary Cross-enterprise User Authentication Authentication & Auditing: Basis for Access Control Document Digital Signature Attesting true-copy and origin Patient Identifier Cross-referencing Map patient identifiers across independent identification domains

21 July 2005Interoperability for Lab - IHE Canada21 IHE: Lab Report Sharing Ready to be implemented ? Gap 1: What standard for a Lab Report Document ? –Today: wrap a complete result in HL7 V2.x into an XDS Document. Already demonstrated at HIMSS –Mid-Term goal: represent lab result as CDA-R2 document with HL7 V3 Lab clinical statements (same as those of the real-time result message). IHE Lab to initiate work in Gap 2: Jurisdiction extensions Gap 3: Laboratory Terminology definition. Likely a national effort initially.

22 July 2005Interoperability for Lab - IHE Canada22 IHE: Interoperability for Health Info Networks By starting with a secured document sharing infrastructure, establish a generic platform on which to extend clinical content (more structure & coded terminology, specialized content). Solid SAML 2.0 authentication and document digital signature (need a PKI). Practical HL7 V3 approach with CDA-R2 (medical summaries) and other content (e.g. imaging, legacy content, PDF, etc.). Establishing a critical mass of products implementations, both in clinical applications and infrastructure for deployment in An architecture that caters to various regional and national architectures: centralized, decentralized and mixed. IHE-XDS is in use in Italy, with projects in Canada (Newfoundland), Norway and France.

24 July 2005Interoperability for Lab - IHE Canada24 Lab to Ambulatory EHR Interoperability Conclusions IHE Lab Scheduled Workflow has a critical role to play: –Solid and proven specification with HL7 V2.5 critical improvements –Bring the rigor and effectiveness of IHE –Consistent approach for laboratories in acute care and ambulatory –Best springboard to HLV3 and Infoway strategic direction Access to historical lab results in a non-lab specific manner is critical: –Leverage IHE Cross-enterprise Document Sharing and associated Integration profiles (e.g. security). –Critical rationalization for ambulatory HER that will need to access other type of record than lab reports. Remaining gaps that need to be addressed (multi-jurisdiction ?): –Results and Orders Coded Terminology –Jurisdictions specific elements
