Task Resource

Error rendering macro 'jira' : Unable to locate Jira server for this macro. It may be due to Application Link configuration.

Task is a FHIR resource that is part of the Workflow Module. Task is used to represent an activity that is to be performed,and track the completion of said activity.

A number of different communication patterns use the Task resource, including the placing and fulfilling laboratory orders..

The OpenMRS data model does not contain a natural mapping of this concept support. In order to support workflows requiring Task, the OpenMRS FHIR module extends the data model with a representation of the Task resource that is stored in the fhir_task table.

Supported Elements

Task.id - The logical identifier of the Task resource
Task.status - The current status of the Task, represented using states from this state machine. The OpenMRS implementation supports requested, accepted, rejected, and completed states.
Task.intent - Represents the actionability of the Task. The current OpenMRS implementation supports only the order value for this element.
Task.basedOn - A reference to the ServiceRequest resource that represents the order that caused the creation of this Task.
Task.encounter - The healthcare event (e.g. a patient and healthcare provider interaction) during which this task was created
Task.for - The entity who benefits from the performance of the service specified in the task (e.g., the patient).
Task.owner - Individual organization or Device currently responsible for task execution.
Task.input- Information needed for performing the Task.
Task.output - Information produced by performing the Task.
