  5. Mission To develop a CIMI modelling methodology, style guide and a set of models, which together demonstrate and test the approach to CIMI clinical modelling.

  6. Terms of Reference This taskforce has been established to: • Further develop CIMI's modelling methodology; • Create an initial set of CIMI clinical models; • Further test and develop CIMI technical models, including: • CIMI reference model • Archetype Object Model 1.5, and • CIMI terminology.

  7. Modelling Taskforce History (2012) May 10 - 12 Meeting in Pleasanton  Modelling Taskforce was established May to Sep Taskforce infrastructure and planning; Modelling methodology; Observation modelling pattern; Heart rate model Sept 14 - 16 Meeting in Rockville  Modelling priorities: Lab Results Report (followed by Immunizations and Body Temperature) Oct to Dec Replanning and review of submitted Lab Result models Design Lab Results model structure and modelling patterns Lab Results - Comparative analysis spreadsheet CIMI Terminology subgroup established October 2012 • Terminology binding use cases, requirements, options, proposal • Lab Results terminology semantic bindings • Lab Results terminology reference sets started • Terminology server requirements Review of CIMI Demographics Reference Model & model analysis Dec 2 – 4 Taskforce meeting in Groningen  Lab Results comparative analysis, mindmaps, implementation, terminology binding, reference model, instances and planning

  8. Overview of CIMI Modelling Approach

  9. CIMI Architectural Overview

  10. CIMI Reference Model - Core

  11. CIMI Reference Model – Data Values

  12. CIMI Reference Model – Demographics

  13. Archetype Object Model (AOM)

  14. CIMI Modelling Layers COMPOSITION CLUSTER ENTRY SECTION Dispensed Medications GUI Laboratory Report Message Implementation Purpose Context Neonatal Blood Pressure in EHR Current Medication List in EHR G.P. Dispensed Medication Item Inpatient Discharge Summary Care Setting Context Home Blood Pressure Outpatient Clinic Current Medication List Dispensed Medication Item Full Blood Count Results Report Use Case Context Standing Blood Pressure Current Medication List Paediatric Medication Item Biochemistry Laboratory Results Report Specialty Context Neonatal Blood Pressure Cardiology Medication List Medication Item Laboratory Results Report Clinical Models Blood Pressure Medication List Material Entity, Observable, Action, Schedule, Address, Clinical Report, Event Summary Patterns Observation, Action Clinical List Reference Model

  15. CIMI’s Modeling Approach • Modular for reusability • Composablefor meeting use-cases • Pattern-based for consistency • Maximal for completeness • Logical for implementation in multiple formats • Constraint-based to allow specialisation • Extensible for local requirements • Bound to terminologyfor isosemanticity & interoperability

  16. Modelling Methodology • Foundations • CIMI Reference Model • Archetype Object Model • CIMI Modelling Patterns • CIMI Style Guide • Modelling Approach • Analyse clinical models submitted (with value sets) • Identify maximal set of data elements • Remove ‘out of scope’ data elements (Style Guide) • Select appropriate CIMI Modelling Patterns(Style Guide) • Define CIMI model (Mindmap, ADL, UML) • Add Terminology bindings • Meaning (nodes, node relationships) • Value sets (maximal set from submitted models) • Add Example Model Data Instances • Technical Validation • ADL, UML • Clinical Validation / Review • Confirm mappings from submitted models

  17. Laboratory Results Report

  18. Submitted Models • FHIR Lab Report resource • Intermountain Standard Lab Obs • NEHTA Pathology Test Result • MOHH Investigation Composition • HL7 Clinical Care Document • Netherlands (NFU) Lab Results • EN13606 Association Lab Test • Canada InfoWay HL7 v3 POLB_MT004000UV

  20. Intermountain – Standard Lab Obs

  21. NEHTA – Pathology Test Result

  22. MOHH – Investigation Composition

  23. HL7 Clinical Care Document - Results

  24. NFU – Lab Results

  25. EN13606 Association – Lab Test

  27. CIMI Laboratory Results Report Design Lab Results Report (Composition) 1 Lab Report Header (Entry) 0..1 Patient Encounter Summary (Entry) 0..* Lab Test Request Summary (Entry) 0..* Lab Test Result (Entry) 0..* Specimen (Cluster) 0..* Test Result Group/Item (Cluster) 0..* Specimen (Cluster) 0..* Reference Range (Cluster)

  28. Identify maximal set of data elements • Comparative analysis of submitted models is used to identify the maximal set of relevant data elements for each model (see spreadsheet)
