Current Context

Current application context can be queried using well known Observation resource identifiers.

Current Provider Identifier

Will return a resource <id> valueString value when a user is currently logged into the clinical system.

This can be used to obtain practitioner details via <fhir-host>/Practitioner/<id>

Note: FHIR STU3 service now had globally (rather than locally) unique identifiers

Direct DLL Call

When hosing your own FHIR service using the FHIR-SERVER.dll you may call the library interface directly to obtain logged in practitioner context:

 Oridashi.Fhir.Host.FhirHost host = new Oridashi.Fhir.Host.FhirHost();

 // start-up the host 

 Oridashi.Fhir.Host.Dstu3.FhirServer server = host.AutoHost;

 string practitionerId = server.ContextPractitioner;

Current Patient Identifier

Will return a resource <id> valueString value when a user is currently logged into the clinical system and a patient record is open and in focus. NOTE: mulitple patients can be open in the clinical system at one time this call indicates the patient record that in the active (current focus) window on screen.

This can be used to obtain current patient details via <fhir-host>/Patient/<id>

Note: FHIR STU3 service now had globally (rather than locally) unique identifiers
