Has anyone had any experience of doing this in the UK?

I'm working for new style regional diagnostics organisation (name will be NHS NW Genomics from April) - we will need to extend the data models in both HL7 v2 and FHIR for enterprise rather than point to point use.

I believe we are the first to attempt this in the UK (xlabs/npex may have done so for laboratory), so not expecting many/any answers :) 
I'm starting with EPIC as it has quite good documentation (and a local NHS Trust is using EPIC as it's EPR). Will be wanting to move onto meditech afterwards. 

The proposed change is being worked on but can be found here https://nw-gmsa.github.io/StructureDefinition-CorrelationIdentifier.html 
This relates to FHIR Identifiers and V2 EI and CX datatypes - I'm calling it a data contract as it crosses standards (and also spread into IHE XDS).
