How to convert FHIR(HTTP GET) Query into HL7
We have a PAS that accepts HL7v2 QBP^Q21 requests, and returns patient details in an RSP^K21.
We have a clinical system that wants to sent an http GET request of the form http://server/getpatientbyid?pid=M1234567
So I think I need to convert the query url into a QBP^Q21 (HL7) message, then take the response in HL7v2, convert to SDA, convert to FHIR, and put that in the response to the original GET.
Does anyone have any experience doing this? is there an approach you would recomend?
