Is reversible mapping between FHIR and Archetypes possible?


I'm trying to understand the risks involved in one system 'speaking FHIR' and another 'speaking OpenEHR/Archetypes'. Especially for the Observation, Questionnaire, Device and Patient resources.

Can the two content formats be mapped between each other seamlessly, possibly utilizing some extensions where required? What are the major issues in such a mapping, and are there people/organisations/vendors who have done such mappings?


Solution

  • The two formats can be mapped to one another, but possibly not seemlessly. They differ fundamentally in scope and intent. And there's different issues for each resource you ask about

    I know of no organizations that have done systematic mappings of the particular resources that you mention. There is some work afoot; for instance, we co-developed the AllergyIntolerance resource and the AdverseReactionRisk archetype, though I don't know how sustainable that will prove. It was hard work to align the community processes and analyses, and it might not be repeatable

    Fundamentally, FHIR and openEHR are doing different things, and have different strengths and weaknesses. A system implementing both is going to do manual mapping between it's internals and externals. Perhaps that will change slowly in the future, but not in any hurry
