Topic: filtering on revinclude
Lieven Peeters (Aug 27 2020 at 14:54):
There's a lastn-operation described for the observation-resource, but currently, that's only defined in the observation-resource.
Did anyone already face the same use case on other resources? And if so, how did you solve that?
E.g. show in a patient overview all patients with their most recent deviceRequest as well.
Fetching all related resources (deviceRequests in this case) from the FHIR-server and filter in the backend of the client-app would be an option, but depending on the kind of resource, that might generate a lot of data-traffic between fhir-client and -server.
For now, I've started from a query to the patient-resources, with a revInclude to get all the related resources. Is there a way to add filtering to that revInclude?
That would also open opportunities for other use cases, like:
"give me the patient(s) and by the way, also their related deviceRequests for devices of type x"

Would be interesting to also see "patient and the MedRequests, but only the latest 5 medRequests"

The search syntax doesn't allow for operations on (rev)includes. Try multiple subsequent (related) searches instead..
