ITI-67

The ITI-67 (Find Document References) transaction allows Document Consumer actors (e.g. primary systems) to query a Document Responder (i.e. the eMedication service backend) for a list of DocumentReference resources that satisfy a set of parameters.

This transaction provides an MHD-based alternative, as profiled by CH EPR FHIR to the ITI-18 (Registry Stored Query) transaction. Note that metadata and business logic constraints on ITI-18 for the eMedication service apply as well for this transaction.

The result of the query is a Bundle (so not directly a collection) containing the DocumentReference resources that match the query parameters (if any).

Further Constraints

The eMedication service does not for now support the identifier parameter. Note that this parameter is in fact not required by the XDS on FHIR option to which the eMedication service is grouped with and whose list of mapped parameters are the ones supported by the service.

Security Considerations

Note that beside the security considerations expressed (directly or indirectly) by the CH EPR FHIR profile, the eMedication service implementation supports only, for now, the SAML Token option, which means that the authorization token conveyed with the HTTP request must be an XUA token.
