Topic: Resources and relationship
Rickard Viktorsson (Apr 11 2018 at 12:34):
(I have just started looking into for FHIR) There are many different types of resources defined in FHIR that can reference each other. Looking at definitions of for example Patient and Observation, it seems to me that you can create an Observation and link it to a Patient only without involving any ProcedureRequest, DiagnosticReport etc. Is that so? Could any configuration in a FHIR server prohibit that?
John Moehrke (Apr 11 2018 at 12:42):
Observations are made before any procedures are ordered, and it is observations that are used to come to some diagnosis...
Rickard Viktorsson (Apr 11 2018 at 13:03):
Ok thanks. I think I was a bit confused on the workflow relationship there Observation is an event resource that reference to a request resource (https://www.hl7.org/fhir/workflow.html).
Grahame Grieve (Apr 11 2018 at 13:21):
it can, but you don't have to. On the other hand, prfiles and implementation guides might make all sorts of rules like that - and the GraphDefinition resource is defined to help make those rules
Lloyd McKenzie (Apr 11 2018 at 14:25):
FHIR doesn't impose any particular workflow. Servers can impose workflow expectations, though that's more common in the messaging and services paradigms where there's more contextual information available to impose constraints.

Hi!
What would be the optional approaches for handling a patient implant? We've looked at putting the information in Device. Issues with Device alone is time of operation, age, dates etc. So I looked at Procedure and putting Device in at focalDevice. Any thoughts on this? Any simplifier examples on how to solve this?

@Michelle (Moseman) Miller, @Eric Haas ?

if implanting: Procedure + focaDevice
if reporting "i had this implanted": deviceUseStatement
Eric Haas (May 08 2018 at 15:12):
Devices/implants can be assigned to patients through Device. The activity of implanting is requested by ServiceRequest the activity is Procedure and the statement is either Procedure or DeviceStatement ( still have not seen a lot of examples of the latter)

@Eric Haas @Lloyd McKenzie @Jose Costa Teixeira Thanks so much for your input, very helpful!
