1.10pm. Our first speaker of the afternoon is Dr Hugh Leslie, Director of Ocean Informatics.
What do we need to make standards work?
- Information models – ensure interoperability, single schema for data consolidation and basis for content specification
- Content Specifications
- Generic way to query the data
- Messaging simplification
- An EHR that is life long, independent and sharable
Hugh then talked us through his model of ‘Ontologies of Everything’ diagram:
Hugh gave us a demo of how the openEHR archetype editor works and talked us through a UML diagram of how text is represented in openEHR.
Clinicians need to be able to find SNOMED CT terms they need, identify the correct term and it should be transparent to the end users.
Applications need ot be able to deploy SNOMED and use it reliably and need to be able to query reliably.
Hugh then demonstrated the OTS Query Editor for creating terminology subsets. He created a new term and used it in the Ocean Informatics Template Designer. He then showed us how to use Archetype Query Language.
Q. Is the terminology server available to use?
A. The server is an Ocean proprietary product so it is not available.
Q. If the terminology server is updated – does that go through to anyone using it?
A. Yes. You can even compare between previous uses of SNOMED CT.
Q. Are there any real big implementations? How do you relate to vendors?
A. Queensland Health, Netherlands (10 hospitals).
Q. Do they have SNOMED in them?
A. No they are not currently using SNOMED?
Q. How does openEHR work with vendors?
A. About 5 vendors in Australia building systems with openEHR backend. There are mappings for exsiting systems that automatically generates XML schema.
Q. Who creates the archetypes?
A. There will be an international releases. The NHS has contributed their archetypes to the openEHR repository.
Q. What thought has been given to a universal security model?
A. Encryption, certificates on different parts of the data. Privacy is about legislation.
Q. How do you create CDAs from archetypes?
A. Can demonstrate but uses a XML transform.


Thanks for blogging, Chris. I’m not usually one of the ‘timely ones’ . However, I like your report here; especially the graphic insert (ontology of everything). Interesting depiction; any ideas as to how nursing might take advantage of this?
Keep up the good work!
