I would like to process a batch on my FHIR Server will some conditional logic. The batch will contain a MedicationOrder entry, a Patient and Prescriber(Practitioner). The client will not know the logical identifiers when it submits the bundle (my FHIR creates logical ids during create) but the client will know the business identifiers for each of these resources. If my logic is to only create a Patient if they don't already exist, then what value should i put to reference the Patient to the MedicationOrder in the bundle. Should I reference using the business identifier?
e.g. <reference value="Patient?Identifier=1234123512341235"/>

well, see the discussion for the Conditional Reference connectathon track:

note that what is proposed there is a change to the specification; having implemented it, it's far from clear to me that this is the overall correct approach to implement this.

and note that you need transaction not batch for this

Hi Paul,

please note that the conditional Reference will not create the Patient if it's missing!

view this post on Zulip Simone Heckmann (May 09 2016 at 14:18):

In that case you should use a conditional create on the patient resource instead

view this post on Zulip Simone Heckmann (May 09 2016 at 14:20):

...or maybe a conditional update, depending on whether you want your patient resource to update an existing resource on the server in case it already exists.
Kind of like this:

Note how the uuid assigned in the fullurl of the bundle entry can be used to create references within the bundle...

view this post on Zulip Paul Barry (May 09 2016 at 22:46):

Thanks Simone,
So just to clarify, the full URL you provided on the patient entry was just a randomly generated Guid by the client?
<fullUrl value="urn:uuid:f9935843-19a2-4a1a-4016-7bea52de77f6" />
You use this uuid to link the patient to the Encounter entry?
<reference value="urn:uuid:f9935843-19a2-4a1a-4016-7bea52de77f6" />
If the patient did exist in this scenario, how would you save the Encounter entry? Would you update the Encounter patient reference to use the Logical Id of the pre-existing Patient?

Thanks Grahame, I am hoping to attend the NCTS connectathon in Melbourne next week. So possibly I could show you a working implementation of this scenario on our FHIR Server?
