task management using FHIR?

Can anyone point me to any examples for task management using FHIR?

Not sure of the context of your question. Assuming that you mean how FHIR supports storing/retrieving of tasks:

  • FHIR DSTU2 - does not have a specific resource for Tasks. “Basic” resource can be used, which is a generic FHIR Resource that can be used to map any unmapped entities.

  • FHIR STU3 / R4 - “Task” resource has been introduced. See the “workflow” category of resources for supporting resources (Appointments, Tasks, Schedule etc)
