Topic: Clarification on some fields in ServiceRequest resource
David La Hei (Jul 30 2018 at 08:40):
I am starting with FHIR things. For an assignment I am looking into the ServiceRequest resource: http://build.fhir.org/servicerequest.html. I have difficulty with understanding the fields instantiates, basedOn, and replaces. Can someone please provide some explanation (practical example)? Or, point me to some documentation? Thanks!

Have a look at http://build.fhir.org/servicerequest-definitions.html, it has further clarification on the fields!

Thanks Vadim, I looked at those clarifications but find them very brief and not that clear.

further background on these fields is based on the request pattern : http://build.fhir.org/request.html
Eric Haas (Jul 30 2018 at 16:34):
for basedOn one request may generate other requests and this field can track that lineage. i.e. my lab order cause a blood draw to be requested.
Eric Haas (Jul 30 2018 at 16:37):
instantiates you need to understand what the target resources are. they are definitional (basically protocols) So if ServiceRequest B is following protocal A you can represent that relationship in 'instantiates`
Eric Haas (Jul 30 2018 at 16:39):
replacesis all about swapping out one request for another. for example, ServiceRequest A is to be used instead of ServiceRequest B for some reason, so SerivceRequest B is retired and A used instead.
