4. What is it?
• A collection of reusable bits of clinical
information – Archetypes
• Top level organisation follows CCR
• Further detail provided by:
– Existing international Archetypes
– Extensions (of above)
– New Archetypes
• Each HIE payload will include a subset
• Don’t worry about Core/Minimum set (for now) –
creating a maximal set
7. Extension: Archetype Specialisation
Problem
Local specialisation
Text or Term Diagnosis
Clinical description
Date of onset Term Diabetes
Date of resolution + diagnosis
No of occurrences Grading Term
Diagnostic criteria +
Stage Diagnostic criteria
• Fasting > 6.1
• GTT 2hr > 11.1
• Random > 11.1
9. Content Development – How to?
• Should be grass-roots; e.g. clinician led
• Tight governance – consistency important
– Independent and multi-stakeholder
– Emphasis on alignment in all HIE Projects
• CKM: tool for collaborative development
• ? Trans-Tasman collaboration – use Nehta DCM
(http://dcm.nehta.org.au/ckm/)
• Terminology bindings: SNOMED RefSets and others
• Need: champions, upskilling and seed funding ;)
10. How to Align?
• Create a superset from all existing sources
• Identify exact matches (label, values etc.)
• Align similar items:
– Labels & descriptions
– Combine value sets
– Adjust granularity
– Adjust cardinalities
– Set terminology bindings
11. Content Localisation
• Localisation:
– Translation (Maori, Chinese, Korean, Indian etc.)
– Adaptation (extensions to NZ needs)
• Content independent of language – as many
languages can be fitted, good tooling
• openEHR Localisation Program (led by myself)
– Local Chapters in each jurisdiction
– Program Committee, Qualified Members, Local
Members
– NZ openEHR Chapter intended to work under HL7NZ

Hi everyone, my name is KA and I work for NIHI. Trained as MD, not practised much, did PhD in ISI sit in HINZ Exec and also board member of HL7NZ and Localisation Program Leader in openEHR (stds kill innovation!)Thanks Ed, all 3 organisations and ALL!After the excellent introduction from my colleagues, Alastair, David and Hugh, today I’ll walk you through some examples I created to develop a uniform content model for NZ. HISO etc.
Published by HISO (2012); Part of the Reference Architecture for Interoperability“To create a uniform model of health information to be reused by different eHealth Projects involving HIE”Consistent, Extensible, Interoperable and Future-Proof Data
Objective of this demo is to show the bottom-up content development approach.Certain Archetypes shared by key HIE (eRef, ePrescribing, PREDICT) undergo an iterative localisation processInternational > Multiple Local projects (added & extended) > Added to ECM
