Why e-Health Standards mostly don’t work

• OMG, HSSP and hopes for better e-Health standardisation
• e-Health standards Crisis
  • Part I – on needs; the basic problem: ‘developing standards’ instead of sourcing them from industry; why ‘choosing standards’ creates hell for vendors and users alike, and may cost millions more than developing something that actually works; why ideas from open source are relevant.
  • Part II – a survey of standards orgs and bad standards; useful ideas from IHE, IHTSDO, HITSP and openEHR
  • Part IIa – what we can learn from OMG
  • Part 3 – some ideas for solving the disaster.
• What needs fixing in e-Health?
• What’s missing from most e-health standards – DESIGN
• Problems and lessons from HL7
  • the CDA ‘dual content’ problem
  • The problem with Null flavours  – Part I, Part II
  • The basic problem with the RIM
  • How HL7 could ‘refresh’

openEHR in the World

• post – openEHR in Norway (2013) – the symbiosis between one innovative vendor (DIPS) and its clinical user base
• openEHR ‘who’s using it?’ page

DCMs, archetypes, clinical element models

• Why three layers of models are needed – information model, archetypes, templates. Why it matters to large scale e-health.
• Stan Huff’s pioneering Clinical Element Models at Intermountain Health. Stan’s ecosystem was created independently of openEHR’s, but the resulting landscape of formalisms, tools and concepts is nearly identical.
• Just the facts Jack – what is a DCM anyway?
• Model Visualisation –
  • openEHR archetype visualisation
  • How mindmaps help clinical modellers… and technical people
• The role of patterns in archetype modelling

Computer Science stuff

• Building information models – a principle for building information models that work – the fundamental ontology property principle.
