Interoperability framework overview
0 likes457 views
The document provides an overview of the goals and framework for developing interoperability standards. The framework aims to 1) develop more computational implementation specifications, 2) tightly link standards development to use cases and certification, and 3) integrate expertise from multiple standards development organizations. It describes a process of developing use cases and functional requirements from the bottom up within a coordinated top-down framework to guide standards development.
Interoperability framework overview
- 1. Interoperability Framework Overview HIT Standards Committee June 24, 2010 Presented by: Douglas Fridsma, MD, PhD Acting Director, Office of Interoperability & Standards ONC
- 2. Goals of the Standards and Interoperability Framework » Move toward more “computational” implementation specifications (IS) • Scalable processes • Ability to develop tools to increase the efficiency of IS development and maintenance • The importance of developing IS that are explicit and subject to less interpretation » Link use cases and standards from inception to certification • Keep the certification processes tightly linked to the standards and IS processes • Support tool development for certification testing • Develop the testing for compliance at the same time as developing the standards and IS » Integrate multiple SDOs with different expertise across the process • Transport packages • Vocabulary • Value sets • Security 6/25/2010

Bottom Up Innovation within a Coordination Framework Standards Pilot Demonstration Development Projects Use Case Development Harmonization of Implementation Reference Certification and Functional Core Concepts (NIEM Specifications Implementation and Testing Requirements framework) Tools and Services (Use Case Development, Harmonization Tools, Vocabulary Browser, Value Set Repository, Testing Scripts, etc)
- 5. Use Case Development Use Case Development and and Functional Requirements Functional Requirements Standards Pilot Demonstration Development Projects The process should Use Case Development Harmonization of » Engage a wide community in and Functional Requirements Core Concepts (NIEM framework) Implementation Specifications Reference Implementation Certification and Testing defining the use cases » Focus on solving a real problem Tools and Services (Use Case Development, Harmonization Tools, Vocabulary Browser, Value Set Repository, Testing Scripts, etc) • Determines scope • Able to “test” if the use case solves the problem » Example of a use case • Prevents “analysis paralysis” • provider wants to send a referral • Does not model in the abstract to a specialist electronically • Open, transparent process » Use case describes » Establish a “use case steward” to • Services shepherd the use cases through the • Standards (package) entire process • Business rules, trust, policies » Output is a clear description (in a That are necessary to satisfy the use computable form) that describes the case standards, services and policies necessary to describe the use case
- 6. Harmonization of Core Concepts (NIEM framework) Harmonization of Core Concepts Standards Pilot Demonstration Development Projects » Need to have a strong harmonization framework that Use Case Development Harmonization of Implementation Reference Certification spans different standards organizations and Functional Core Concepts (NIEM Specifications Implementation and Testing Requirements framework) • XML/UML computational Tools and Services (Use Case Development, Harmonization Tools, Vocabulary Browser, Value Set Repository, Testing Scripts, etc) descriptions of the use cases • Strong governance and transparent processes • Use-case driven (bottom up) » Multiple use cases might with top down coordination have overlapping standards, » Harmonization processes need services or policies to describe • E-prescribing and adverse • Standards • Services event reporting • Policies • Clinical care summary and In standard ways quality reporting • Laboratory data exchange and clinical decision support
- 7. Harmonization of Core Concepts (NIEM framework) Harmonization of Core Concepts Standards Pilot Demonstration Development Projects » Standards harmonization Use Case Development Harmonization of • Leverage best practices • Use the NIEM processes Implementation Reference Certification and Functional Core Concepts (NIEM Specifications Implementation and Testing Requirements framework) • Create explicit data Tools and Services (Use Case Development, Harmonization Tools, Vocabulary Browser, Value Set Repository, Testing Scripts, etc) exchange package that describe the data elements, vocabularies and value sets » Three parts to harmonization » Service harmonization • Information model • Description of the standards • Services description (the data that is exchanged) • Conformance description • Description of the services • Governance (business rules) (the functions that will be descriptions supported in the exchange) » Policy descriptions • Harmonization of policies is a • Description of the policy challenge (trust, business rules, etc)
- 8. Harmonization of Core Concepts (NIEM framework) What is the NIEM process? Standards Pilot Demonstration Development Projects » National Information Exchange Use Case Development and Functional Harmonization of Core Concepts (NIEM Implementation Specifications Reference Implementation Certification and Testing Model Requirements framework) » Started as a DoJ initiative, but the Tools and Services (Use Case Development, Harmonization Tools, Vocabulary Browser, Value Set Repository, Testing Scripts, etc) processes have been generalized • Supported data integration and reporting for Patient Recovery.gov • Used by HHS to support child Discovery Lab data E-prescribing exchange Provider Future and family services address lookup Domains Common • Recommended by OMB as Discharge Core Summary Quality reporting best practice PHR Child and • Used by state and local Family exchange Patient summary Services governments
- 9. Harmonization of Core Concepts (NIEM framework) What is the NIEM framework? » A common core of concepts, explicitly defined, that are shared across different use cases or Patient Discovery domains Lab data E-prescribing exchange » Naming and modeling Provider address lookup Future conventions that allow different Domains Common groups to work independently but Discharge Core Quality harmonize the work together Summary reporting » Based on the ISO-11179 metadata Child and PHR Family standard used by the NCI, NLM, exchange Patient summary Services and standards organizations. 6/25/2010

Standards Development Standards Development Standards Pilot Demonstration Development Projects » Gaps in existing standards Use Case Development and Functional Requirements Harmonization of Core Concepts (NIEM framework) Implementation Specifications Reference Implementation Certification and Testing • Data package • Value sets • Services Tools and Services (Use Case Development, Harmonization Tools, Vocabulary Browser, Value Set Repository, Testing Scripts, etc) » Can be identified as part of the use case development and harmonization process » Work with SDOs (NLM, HL7 etc) to fill in gaps » Allows the standards work to proceed in parallel with development of the implementation specifications
- 11. Implementation Specifications Implementation Specifications Standards Pilot Demonstration Development Projects » If the standards, services and Use Case Development and Functional Harmonization of Core Concepts (NIEM Implementation Reference Certification policies are the ingredients, Specifications Implementation and Testing Requirements framework) then the implementation Tools and Services specification is the recipe (Use Case Development, Harmonization Tools, Vocabulary Browser, Value Set Repository, Testing Scripts, etc) » Packaged together to support » An implementation use cases specification becomes a » Guides development of explicit description of the reference implementation • Standards » Interim Final Rule requires • Services creation of Implementation • Policies Specifications where they don’t exist » That conform to adopted standards and have sufficient detail to be implemented
