openEHR Technical Workshop Intro MIE 2016

  1. 1. Ian McNicoll Co-chair openEHR Foundation freshEHR Clinical Informatics Ltd. Operon Systems Ltd Hon. Research Associate UCL openEHR: Introduction
  2. 2. What is openEHR? An open specification for a health information model capable of supporting an open platform ecosystem vendor neutral technology neutral licensed to allow open and closed source business models
  3. 3. Two-level modelling
  4. 4. openEHR - Specifications Normal technical specifications with UML diagrams etc openEHR Reference model how the health data is represented in a patient record openEHR Archetype object model how the clinical content definitions are represented separately from the Reference model
  5. 5. openEHR: Archetypes open source computable models of discrete clinical concepts Familiar components of a health record Blood pressure, Body weight Medication order, Family history Capture as many clinical perspectives as possible
  6. 6. openEHR: Templates Templates deliver the datasets by aggregating archetypes together Key clinical endpoint and start point for generation of technical artefacts i.e. openEHR archetypes and 
 templates can be used directly Class libraries, Message schema GUI skeletons, API Profiles
  7. 7. AQL: Information-model querying Information model querying, independent of the actual database querying vendor/technology neutral querying
 To query an openEHR system you only have to know which archetypes are in use.
  8. 8. However …. Building an openEHR back-end (CDR) is straightforward just follow the specifications
 BUT building a high-quality openEHR back-end is challenging must understand archetypes/templates must support information-model querying must be fast and flexible not a trivial engineering exercise
