Hi @censon We don’t currently collect the data in OpenEMR that would populate the interpretation property on vitals. I haven’t heard of any discussion to add that in.
I’m the developer currently implementing the US-Core FHIR Vitals observations which is a more limited subset then the full FHIR R4 standard you mentioned. We are prioritizing getting all the requirements completed for ONC certification so I don’t see us implementing this in the next few weeks.
When you say supporting the change, are you a developer and feel comfortable adding working in PHP/OpenEMR? I can point you to the relevant files and you can create a pull request if you’d like. If you don’t feel comfortable doing that, you can private message me to describe more what you have in mind of supporting the development work.
