  1. The following request searches for an active Organization whose name contains ‘Medical’: GET [base]/Organization?active=true&name:contains=Medical
  2. The following request searches for a Practitioner named ‘Müller’: GET [base]/Practitioner?family=Müller
  3. The following request searches for a Practitioner with the GLN ‘7601000102737’: GET [base]/Practitioner?identifier=urn:oid:2.51.1.3|7601000102737
  4. The following request searches for all Practitioners working at the ‘HUG’ organization: GET [base]/PractitionerRole?organization=Organization/HUG&_include=PractitionerRole:practitioner

Find Matching Care Services Response Message

The response message is a Search Results Bundle that contains Organizations, Practitioners and PractitionerRoles. An example of response message is provided.

Retrieve Care Services Resource Message

The Retrieve Care Services Resource is conducted by executing an HTTP GET against the Care Services Selective Supplier’s Care Services Resource URL, providing the resource id of the resource being retrieved. The target is formatted as: GET [base]/[resource]/[resourceId]. Some examples are

  1. Retrieve the Organization ‘Spital X Dept. 3’: GET [base]/Organization/SpitalXDept3.
  2. Retrieve the Practitioner ‘Dr. Peter Pan’: GET [base]/Practitioner/DrPeterPan.
  3. Retrieve the PractitionerRole ‘Dr. Peter Pan at Praxis P’: GET [base]/PractitionerRole/PeterPanPraxisP.

Retrieve Care Services Resource Response Message

The Care Services Selective Supplier shall respond to this query by sending a single Care Services Resource instance.

  • If the Care Services Selective Supplier finds the resource, HTTP 200 OK is returned with the resource (an Organization, Practitioner or PractitionerRole).
  • If the Care Services Selective Supplier does not find the resource, HTTP 404 Not Found is returned with an OperationOutcome resource.

Security Considerations

TLS SHALL be used. This national extension enforces authentication and authorization of access to the Care Services Selective Supplier using the IUA profile with basic access token. Consequently, the Find Matching Care Services [ITI-90] request must authorize using the Incorporate Access Token [ITI-72] transaction of the IUA profile.

The actors involved shall record audit events according to the Audit Event for Find Matching Care Services for Read by the Care Services Selective Supplier and Consumer or the Audit Event for Find Matching Care Services for Query by the Care Services Selective Supplier and Consumer.
