  1. Detailed Clinical Models for Medical Device – Domain Analysis Model – Domain Analysis Model HL7 May 2011 Ballot

  2. Overview • Detailed Clinical Model (DCM) • Describes clinical information structure • Promote semantic clarity • Standard Terminology is built-in rather than an afterthought (e.g. primary and secondary standard-based coding system) • Structured information • Support for process improvement and • Interoperability and automation • Reusable in many contexts • Application development • Interoperability • New standards • Profiling existing standards • Domain Analysis Models • Describe the stakeholders requirements to a integrators, developers, vendors, etc. • Communication among stakeholder groups • Modeling language helps communication, identifies main concepts, and leads to consensus • Methodology that supports the development of DCMs

  3. Approach 1 2 • Requirements illustrated by scenarios • Use cases identify the capabilities and users involved • Details use cases as clinical scenarios • Define information required to support the clinical workflow and interoperability between the systems involved 3 4

  4. Use Cases – specify Actors • Indentify the users roles and/or systems involved in the clinical scenario(s) Is a Clinician… Clinician roles Is a Care Team Member… Care Team Member roles

  5. Use Case Analysis –Business Use Case Actor participation • Use cases • Active verb • Based on scenarios • Narrative description • Preconditions • Steps  Workflow • Postconditions • Actors • Participate • Roles of users • Roles of systems Workflow 3 Use Case

  6. Actor Information produced by a step Clinical Workflow Process Step Trigger Information – input into a step Decision Device Data produced by a step

  7. Information Derived from Workflow Analysis EHRS Data Required • High-level, identifies the information “domains” the precursors to DCMs Device Configuration Device Observation Common/Shared Information

  8. Focus of the analysis: Medical Devices • Emphasis on device-to-device and device-to-system interoperability and automation Device Configuration Device Observation Common/Shared Information

  9. Information Analysis goes deeper… class association repetitions attribute Data type for date/time

  10. DCMs provide the final level of detail : Standard Terminology Is a “Ventilator Setting” DCM Candidate Parameter properties Terminology Constraints Inherited Constraints

  11. Conclusions • This ballot is informative and will expanded as new requirements and use cases are identified • The ballot artifacts are intended to be used: • by providers • To express semantic interoperability needs requirements (e.g. RFPs) • by consortia • To develop IHE Integration and Content Profile • by standard development organizations • To develop new standards for interoperability • Ballot: V3 Ballot  Domain Analysis Models: • http://www.hl7.org/v3ballot/html/dams/uvdmd/uvdmd.html • Project Site: http://gforge.hl7.org/gf/project/dcmmd/ • Releases: http://gforge.hl7.org/gf/project/dcmmd/frs/
