## Resource Profile: CAeReCTask

Official URL: http://hl7.ca/fhir/eReferral/StructureDefinition/CAeReCTask | Version: 0.1.0
Draft as of 2024-08-15 | Computable Name: CAeReCTask

A task resource describes an activity that can be performed and tracks the state of completion of that activity. It is a representation that an activity should be or has been initiated, and eventually, represents the successful or unsuccessful completion of that activity.

Usage:

- Use this Resource Profile: CAeReCBundle
- Refer to this Resource Profile: CAeReCMessageHeader
