When thinking about how FHIR is going to be implemented ‘for real’, it’s likely that ‘green fields’ applications – where there is no existing standard in use – will be early adopters – mobile is an obvious example.
But inevitably, we’re going to need to manage situations where HL7 standards are already in use and we want to introduce FHIR as well – i.e. the two standards are going to co-exist.
There’s a lot of work underway with mapping CDA (and CCDA in particular) to FHIR resources – indeed this work will provide a valuable ‘peer review’ for the completeness of FHIR resources, but in this post let’s have a look at how we might introduce FHIR into an existing HL7 version 2 based infrastructure.
