Project Information

Scope Statement

Project Insight

Use existing PC-defined clinical requirements to create a set of CIMI observation result models with semantic tags appropriate for automated classification. This exercise will

  • Demonstrate CIMI capability & identify additional requirements for CIMI from PC perspective
  • Demonstrate how DAMs may be compositionally related to DCMs & identify gaps in HL7 development framework
  • Demonstrate relationship between information models and logically computable expressions

The content scope will be drawn primarily from the skin assessment DAM, but it may be augmented to demonstrate critical requirements such as negation. It may further phase the analysis to ensure key patterns (lab test, vital sign, assessment instrument) can be represented before addressing the question of how large numbers of these clinical statements are assembled into compositions.

A related project may implement these models in a specification generation tool (such as MDHT, Art Décor, or a FHIR server), generate a specification, implement the specification in software, & test. These steps are not in scope for this investigative project scope statement.

Meeting Information


  • Confirm scope: in process
    • phase 1 scope (suggestion)
      • coded observation (skin condition)
      • quantitative observation (BMI)
      • assessment (Braden)
      • negation (device?)
  • Confirm output targets
  • Confirm tooling
  • Draft first iteration (test each type of statement)
  • Refine
  • Draft second iteration (full use case)
  • Refine
  • Provide feedback to CIMI & PC

Issues/Hot Topics

  1. Use of LOINC & SNOMED CT
  2. Model binding approach for output formats (e.g., FHIR)
  3. How to address composition
  4. Immature observable model
