FHIR PATCH for MedicationStatement
Submitting WG/Project/Implementer Group
This is something FHIR Core requested feedback on DSTU 2: http://hl7.org/fhir/dstu2/http.html#update
Justification
There are real world use cases for some form of PATCH, for example, to update only the status of a specific resource, to update or add a comment, and many other single or limited field updates. With the way FHIR currently defines an update, the client should send in the full resource exactly as received, with the single field changed. This is sometimes challenging, both for the FHIR server and the Client. For example, if a client application does not support storing a specific field the server exposes, how will it send it back? If the FHIR server receives an update request where a field is missing, how does it know the intention was to blank/null that field out?

Expected participants
Cerner (Jenni Syed)
Grahame Grieve
Roles
EHR
Exposes the FHIR MedicationStatement resource with GET (search) and PATCH methods available.
FHIR Client
Has the ability to GET and PATCH MedicationStatement.
Scenarios
Search MedicationStatement
- Action: FHIR Client sends GET to EHR /MedicationStatement resource with patient parameter
- Precondition: EHR should expose GET resource with the JSON format
- Success Criteria:
- Bonus point: MedicationStatement must expose the meta.versionId and meta.lastUpdated fields and support search by patient.
Patch MedicationStatement
- Action: FHIR Client sends PATCH to EHR /MedicationStatement resource using JSON Patch format to update the MedicationStatement.status
- Precondition: EHR should expose PATCH resource honoring the JSON Patch format.
- Success Criteria:
- Bonus point: Rejecting the update if there is a version conflict. Support for updating other fields (eg: note).
Grahame's comment: JSON Patch is pretty dumb. There should be better ways to patch. I'll propose one....
Example Patch
PATCH open/Patient/1 HTTP/1.1 Content-Type: application/json-patch+json
[{ "op": "add", "path": "/active", "value": "false" }]
