  1. Interchange vs Interoperability Syntax  StructureSemantics  Meaning • Main Entry: in·ter·op·er·a·bil·i·ty: ability of a system ... to use the parts or equipment of another systemSource: Merriam-Webster web site • interoperability: ability of two or more systems or components toexchange information and to predictably use the information that has been exchanged. • Source: IEEE Standard Computer Dictionary: A Compilation of IEEE Standard Computer Glossaries, IEEE, 1990] Semanticinteroperability Syntacticinteroperability (interchange) Source: Charles Mead, MD, HL7

  2. Computerized doesn’t mean syntactic interoperability 6 1 5 2 3 4

  3. Concept 1 Concept 2 “We need to sign off on the protocol by Friday” • “Protocol XYZ has enrolled 73 patients” Thing 1 Thing 2 Study Document Concept 3 Thing 3 “Per the protocol, you must be at least 18 to be enrolled” Plan Semantic interoperability: “Protocol” and the Semiotic Triangle Symbol “Protocol” Source: John Speakman/Charlie Mead

  4. Semantic Interoperability • To understand the data being received you must know both: • The definition of each element of data, and its relationship with each of the other elements • you must have a semantic model of the data and • The terminology to be used to represent coded elements, including the definitions, and relationships within the terminology Source: HL7

  5. Current Organization of the BRIDG project FDA HL7 • BRIDG Advisory Board • Representation from the current stakeholders • Help to allocate priorities and identify resources • Assist with vetting the model in the various constituents • Technical Harmonization Group • Responsible for ongoing model maintenance • Developing shared harmonization processes • Multiple subdomain projects • Representation from pharmaceutical companies, technology companies, government agencies, and cancer centers CDISC caBIG NCI PhRMA BRIDG Advisory Board CDISC caBIG HL7 BRIDG Technical Harmonization Group

  7. Model organization • Dynamic View • Captures the business process decomposition of the lifecycle of clinical trials research

  8. Behavioral Aspects of BRIDG

  9. Behavioral Aspects of BRIDG Roles are defined in the swim lanes with examples drawn from discussions with the domain experts

  10. Behavioral Aspects of BRIDG The activities are described in activity diagrams that can be drilled down to provide additional detail. These are linked to the static (logical) portions of the model

  11. Model organization • Logical View • Contains three core packages • Harmonized elements • Staging Area • Manual review area • Addition resources • HL7 V3 RIM • Contains the semantics for the static objects (data) that is used in clinical trials research • Currently have 9 subdomain models in the process of harmonization

  13. Harmonized BRIDG elements

  14. Models in the staging area

  15. Harmonizing attributes

  16. Adding tags to provide semantic traceability (and notes)

  17. Simple semantic can be tracked in tagged values

  18. This linking can be extended down to the CDE level

  19. More complex relationships

  22. Project Team Activities Items for submission – POC, Project Name, project description, high-level project schedule, project Sponsor, etc. Register Project with BRIDG & submit Project info. BRIDG THC assigns Mentor A BRIDG mentor will be assigned to your project Download BRIDG Replica Begin modeling using BRIDG replica and follow BRIDG guidelines Refer to best practices for modeling in BRIDG environment Submit BRIDG Harmonization Package to THC Harmonization Package artifacts – the EAP file, package level xmi Export, Modeling analysis & harmonization document) Submit BRIDG Harmonization Package to THC Meet with BRIDG THC to harmonize project model (virtual or F2F meeting)

  23. BRIDG THC Activities Review the Project Registration material. Assign Mentor to project BRIDG mentor will be available to answer questions Take project to BAB and assign priority and timeline for harmonization Inform Project POC May require some negotiations based on other efforts Review harmonization Package submission Perform analysis and prepare for harmonization meeting Schedule project Harmonization meeting Develop harmonization Results package for project team
