This is meant to be high level and a ‘fag packet’. (I am looking at understanding COMPOSITION and making notes as I go along and based on the diagram from here EHR Information Model ) Any major issues? [image]

Hi Kevin, thanks for sharing. Could you elaborate a bit more please, in what you’re trying to achieve. It’s sometimes a bit hard to judge what’s coming from where. E.g. the “patient details” composition, where is that name defined and by whom?

My background is HL7 and trying to understand openEHR. So I’m really try to map my current understanding to openEHR. This might be a technical (and incorrect reply :slight_smile: ). I think openEHR has it’s own copy of patient_details, I’d assume this is sync’d with a PAS system via HL7 v2 (or ope…

There is an openEHR Demographics model which can be used to store PAS-type information and/or staff details but ? most openEHR implementers do not use this but just use an existing PAS/ Demo service, often via a FHIR wrapper. For your purposes, I’d suggest largely keeping formal patient demographic…

Thanks for making the effort to understand openehr. In my experience mappings like this are useful as a discussion starter. But since the perspective of the specs (‘exchange vs persistence’) and the scope of the models (e.g. openEHR COMPOSITION vs resource) is very different. It quickly will become …

I’ve actually gone for a two phase map. Phase 1 - Template → FHIR Questionnaire and then Composition → FHIR QuestionnaireResponse. Phase 2 - Use FHIR SDC and in particular this Form Data Extraction - Structured Data Capture v3.0.0 as an approach mapping to other resources. Initial tests appear to…

[image] ian.mcnicoll: most openEHR implementers do not use this but just use an existing PAS/ Demo service, often via a FHIR wrapper. And using the PARTY_PROXY.external_ref field that is inherited into PARTY_SELF, PARTY_IDENTIFIED etc.

Spoke with @ian.mcnicoll yesterday. In my FHIR conversion, I’m trying to get two conversions which: Is used to build a UI for capturing the data (it resembles how templates are displayed in CKM) Can be used to render Composition in a UI Has mapping metadata for conversion between HL7 standards a…

This might also serve as a bridge between openEHR and LOINC Panels Panels and Forms – LOINC which I’m presuming are often implemented at HL7 v2 ORU.

LOINC exposes these panels via a FHIR Server LOINC Terminology Service using HL7® FHIR® – LOINC I think it’s possible for CKM to do similar and expose openEHR definitions and terminology as FHIR CodeSystem, ValueSet and Questionnaire Main reason for doing this is to allow developers (well me at l…

This probably has overlaps with Introducing FHIR Connect I was using Betters One London UCP as a use case, but wasn’t aware of fhir connect. Main difference is I’m seeing a FHIR conversion which is more like Composition (FHIR QuestionnaireResponse). FHIR QuestionnaireResponse can be mapped to othe…
