AZURE FHIR APIs : support for _since and _lastupdated- Need to know which resources supports either of them or both

Question

In Azure API for FHIR, How to find which resource supports _since parameter and which ones do not, in case a resource does not support _since we need to use _lastUpdatedated

However for our analytics solution we need to have this information in advance so that we can write the code accordingly.

For example when we executed a GET calll for Patient resource using _since we got this error "The search parameter '_since' is not supported for resource type 'Patient"

However when we use _lastUpdated it works fine.

Can you please provide a way to find which resource supports _since and which ones supports _lastUpadted and both, there are over 150 resources finding this manually will be very challenging.

Thanks,

Neeraj.

Neeraj Shrivastava Thank you for posting your question in Microsoft Q&A. Azure API for FHIR is fully managed service (PaaS offering) by Microsoft and is an implementation of FHIR standard defined in https://hl7.org/fhir/ The latest version supported is 4.0.1 and Rest API operations and extended operations are defined here.

_since parameter is defined in Patient-everything operation which you can see it in https://hl7.org/fhir/patient-operation-everything.html as well as https://learn.microsoft.com/en-us/azure/healthcare-apis/fhir/patient-everything#patient-everything-parameters. Few other operations also support this parameter and check here.

For search operation, _lastupdated parameter is supported for all resources as defined in https://build.fhir.org/search.html#all. I recommend you review the specification in the FHIR standard to identify which parameters are supported for specific operations or resource types.

I hope this helps with your question and let me know if any other questions.
