Hi,
I am wondering if there has been some work done regarding transformation of HL7v2 to OpenEHR compositions ?
Thanks,
Mateen
Hi Mateen,
There has a lot of work done in many settings on v2 to openEHR integration, particularly labs and ADT- most of the openEHR vendors will have a bunch of examples. THe real challenges are the variability in the way tha v2 messages are setup and the further variability in how labs actually populate the messages.
I have some lab examples but they were part of some commercial work so will need to get permission to share.
There is also some design dpocumentation at https://github.com/freshehr/rippleosi_models/tree/master/docs/iEHR
based on Irish V2 messages.

Hi,
I think most mappings are implemented in an ad-hoc way, most cases I know are implemented in plain code, some might use some kind of low level mapping tool. I’ve been doing mappings with HL7 v2.x, v3 and FHIR to/from openEHR for a while and I tend to use Mirth Connect for that because it reduces the code needed and some parts are just configuration, like the communication protocol handling and some parsing.
Mirth is an integration engine, basically you receive data in some format via some protocol, and it helps to build transformations over that format that will end up in another format sent to an external app in another protocol. Besides reducing dev time also can reduce errors because less programing is needed. It’s also open source.
That is just my experience 
Best,
Pablo.

Hello @ian.mcnicoll , I am having similar question which is on determining what would be the best way to create compositions based on a Lab Report (HL7 v2) that has multiple observations in it.
I have two questions lingering; either to create each observation in the LabReport as an individual composition within the openEHR repository or to create the entire LabReport as a single composition.(All observations of the report having the same composition ID).
What would be the best approach to this? Or what is the recommended way to create these compositions?
Both would work from a querying POV but I would normally have a target composition for the whole V2 message, as this closely represents the way that the information is delivered.
@Simon and his colleagues at FuturePerfect have a fair amount of experience with this.
The minimum pattern is at
Basically OBR-> Observation Lab test and each OBX maps to a CLUSTER Lab analyte.
THis is based on older versions of the lab test archetypes but you should get the idea.
