U.S. Pat & TM Off HL7 Vision and Mission HL7 Vision To Create the Best and Most Widely Used Standards in Healthcare HL7 Mission HL7 provides standards for interoperability that improve care delivery, optimize workflow, reduce ambiguity and enhance knowledge transfer among all of our stakeholders, including healthcare providers, government agencies, the vendor community, fellow SDOs and patients. In all of our processes we exhibit timeliness, scientific rigor and technical expertise without compromising transparency, accountability, practicality, or our willingness to put the needs of our stakeholders first.

7 7 © Health Level Seven ®, Inc. All Rights Reserved. HL7 and Health Level Seven are registered trademarks of Health Level Seven, Inc. Reg. U.S. Pat & TM Off A Twenty-Second Interoperability Quiz… Are you interoperable… … if you and your business partners speak different languages … if gender = 01 means male in your business and female for your business partner? …if the primary context for information sharing is or fax? …if electronic data is exchanged via CD-ROM, or DVD-ROM? …if you use XML? …if you use Web Services?

U.S. Pat & TM Off The 20 Second Agility Quiz How well does your organizations IT adapt to… … address the new business rules that resulted from a legislated policy? … deployment changes resulting from adding a data center? … integrating clinical information with a new business partner? … integrating with the new system … emerging public interest in personal health records?

U.S. Pat & TM Off Wouldnt it be nice if… …your organization could use any MPI you chose without re-integrating? …you could painlessly integrate data from new clinical systems into a patients health summary / cover sheet? …heterogeneous systems could be accessed consistently from your installed application base …standards supported your ability to redeploy or distribute hardware and software without breaking things

11 11 © Health Level Seven ®, Inc. All Rights Reserved. HL7 and Health Level Seven are registered trademarks of Health Level Seven, Inc. Reg. U.S. Pat & TM Off How is SOA different from messaging? A common practice in healthcare, just not yet in healthcare IT Many key products use them but do not expose interfaces Ensures functional consistency across applications Accepted industry best practice Furthers authoritative sources of data Minimizes duplication across applications, provides reuse Messages can be either payloads in or infrastructure beneath services Service-oriented architecture provides the framework for automation of common services Still, SOA has to be done well. It is cheaper and easier than ever to create badly designed applications and spaghetti integration

12 12 © Health Level Seven ®, Inc. All Rights Reserved. HL7 and Health Level Seven are registered trademarks of Health Level Seven, Inc. Reg. U.S. Pat & TM Off Why SOA Healthcare Standards?

13 13 © Health Level Seven ®, Inc. All Rights Reserved. HL7 and Health Level Seven are registered trademarks of Health Level Seven, Inc. Reg. U.S. Pat & TM Off Why develop healthcare SOA standards? Healthcare organizations are being driven to interoperate Messaging is not the ideal approach for every interoperability challenge SOA has demonstrated viability and benefits for many organizations and in many vertical-markets

U.S. Pat & TM Off SOA In Action… An Identity Management Example Local/Regional Domain 2 Regional Identity Service (EIS) service client Implementation Interface National Identity Service National/Master Domain service client Interface Implementation External organizations system Local/Regional Domain 1 Local Identity Service service client Implementation Interface 1. Query local domain: entity found locally 2. Query local domain: entity not found locally, retrieve from master domain 3. Query master domain: retrieve linked entities from master domain Scenarios 4. External System Query: Retrieve from master domain

U.S. Pat & TM Off The Healthcare Services Specification Project (HSSP) 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

18 18 © Health Level Seven ®, Inc. All Rights Reserved. HL7 and Health Level Seven are registered trademarks of Health Level Seven, Inc. Reg.
