3 Page 3 ©2005, Ken Rubin A little personal background… Approximately 15 years of IT experience Approximately 8 years health informatics experience Roles: –Veterans Health Administration Health Information “Application” Architect EDS-VA Segment Chief Technologist –Standards Chair, OMG Healthcare Domain Task Force Chair, HL7 Services Specification Project Past Chair, HL7 Process Improvement Committee

4 Page 4 ©2005, Ken Rubin About Healthcare Standards…

5 Page 5 ©2005, Ken Rubin Why do we care? Business View –Business demand to interoperate –Required for regulatory/statutory compliance; beneficial reimbursement –Patients receive care at many places –Consumers demand interoperability. “Why am I giving you this information again?!” Technical View –Collaboration with business partners forces the need for IT interoperability among them –Facilitate the integration of new technologies and products –Minimize risk of vendor lock-in –Reduce cost of design, development, maintenance

6 Page 6 ©2005, Ken Rubin Lets examine the impact of standards… How would you … –Integrate a new laboratory system into an enterprise? –Share patient demographic information with insurers? –Collect information on your patient for an inpatient visit from their primary care provider? –Send disease registry information to the NCI? –Support drug-order checking? –Validate that a new EHR system performs to industry expectations of functionality? –Purchase systems that will work within your business?

9 Page 9 ©2005, Ken Rubin HL7 Overview

10 Page 10 ©2005, Ken Rubin HL7… …is a not-for-profit, ANSI accredited Standards Development Organization (SDO) …has affiliates in 30+ countries …uses an open consensus standards process …comprises ~450 organizational members including providers, vendors, consultants …has 1700+ total members …routinely has 500+ attend Working Group Meetings Slide content provided by Helen Stevens and Gordon Point Informatics, used with permission.

11 Page 11 ©2005, Ken Rubin Why is it significant? Collection of many of the healthcare industry thought-leaders and top talent Strong international presence and perspective Broad participation and consensus process “Networking” Viewed as the lead in healthcare IT Regulatory agencies are increasingly using HL7 for mandated healthcare standards

13 Page 13 ©2005, Ken Rubin Key Events in HL7’s History 1987Consortium of health providers, vendors, consultants produce Version 1.0 prototype 1994Accredited by ANSI 1990 - 1999Versions 2.1-2.3.1 “production” standards 2000Version 2.4 2001+Version 3 begins phased release 2002Version 2.5 2003Version 3.0 starts ANSI Accreditation Slide content provided by Helen Stevens and Gordon Point Informatics, used with permission.

14 Page 14 ©2005, Ken Rubin How does HL7 work? ANSI Rules: –Open Membership –Consensus Driven –All votes must be reconciled during meetings –Negative votes must be withdrawn or found ‘non- persuasive’ –2 Levels of balloting – Committee and Membership –90% of votes in Membership level ballots must be affirmative to pass –Single persuasive vote may halt the standard Slide content provided by Helen Stevens and Gordon Point Informatics, used with permission.

15 Page 15 ©2005, Ken Rubin Version 2 Messaging standard in pervasive use throughout the industry Uses its own message Encoding Rules –(Uses|delimiters|to|separate|fields, components, and sub- components) –Field location indicates the semantics of a field (e.g., PID.3 – Patient Identifier) –“Z”-elements for extending the standard for custom segments, fields, events Practical and useful as a standard, but not without issues –“Optionality” – great for uptake of the standard but bad for interoperability –Not “plug-and-play” –Refinement required: conformance using Message Profiles Scope covers Patient Administration, Orders and Observations, Scheduling, Financial Management

25 Page 25 ©2005, Ken Rubin Standards and the Electronic Health Record

26 Page 26 ©2005, Ken Rubin Why Standards are Crucial for EHR An EHR is the culmination of lifetimes of medical information in support of clinical care Rarely does anyone receive all their care from one provider [organization] The “longitudinal” record is of high value, but it must be assembled from multiple sources Assembly itself is VERY difficult Assembly of quality, semantically meaningful, and consistent data has been near impossible to date

27 Page 27 ©2005, Ken Rubin Many Standards Play in the EHR EHR Definitional Standards [ISO] EHR Functional Standards [HL7, ASTM] EHR Access Standards [HL7, OMG] EHR Structural Standards [HL7, ASTM, CEN]

28 Page 28 ©2005, Ken Rubin HL7 Electronic Health Record Functional Model Does not contain a definition of the EHR Enumerates functionality that the community has attributed as useful for EHR Provides a mechanism for “profiling” Electronic Health Records by attributing functions to care settings Standard Care Setting Profiles are being balloted by “realm” (e.g., countries, regions, and municipalities) Available at

31 Page 31 ©2005, Ken Rubin Standards on the Edge

32 Page 32 ©2005, Ken Rubin What is the Healthcare Service Specification Project? An effort to create common “service interface specifications” tractable within Health IT A joint standards development project involving Health Level 7 (HL7) and the Object Management Group (OMG) Its objectives are: –To create useful, usable healthcare standards that address functions, semantics and technologies –To complement existing work and leverage existing standards –To focus on practical needs and not perfection –To capitalize on industry talent through open community participation

33 Page 33 ©2005, Ken Rubin Where would these specifications be used Inter-Enterprise (such as RHIOs) –By functionally specifying behavior, roles between applications and products are clarified, and the technologies supporting them can be profiled and sharpened Intra-Enterprise –Standardization on functionality allows for better integration of off-the-shelf and custom development environments, and promotes more of a “plug and play” environment Intra-Product –Facilitates vendors ability to integrate third-party value-add components and speed design phase with higher confidence Custom-Implementation –Affords organizations wishing to custom-develop the opportunity to later integrate off-the-shelf

36 Page 36 ©2005, Ken Rubin The Impacts of Standards Business –As a vendor? As a provider? As a payer? As a supplier? –Ability to grow market, penetrate organizations, establish market share –IT solutions for mergers/acquisitions –Implications on procurement? Architectural –Product design impacts –Technology insertion –Cost reduction/avoidance –Time-to-market Innovation –Collaboration resulting in creative solutions –Disruptive agent –Market pressure “Keep up with the Joneses”
