Clinical Order Workflows
1.0.0-ballot - STU 1 Ballot

Clinical Order Workflows, published by HL7 International / Orders and Observations. This guide is not an authorized publication; it is the continuous build for version 1.0.0-ballot built by the FHIR (HL7® FHIR® Standard) CI Build. This version is based on the current content of https://github.com/HL7/fhir-cow-ig/ and changes regularly. See the Directory of published versions

## Resource Profile: Coordination Task

Official URL: http://hl7.org/fhir/uv/cow/StructureDefinition/coordination-task | Version: 1.0.0-ballot
Standards status: Trial-use | Maturity Level: 1 | Computable Name: CoordinationTask

Minimum expectations for a Task resource when created or updated for the purpose of managing the workflow for performing a request. This profile is used to describe the 'please fulfill' request from either a known performer, or by one who is yet to be determined. The information is obtained RESTfully by the recipient either via polling, or as the result of a subscription notification about the existence of the Task resource

Usages:

- Refer to this Profile: Cancellation Request Task, COW Message Header and COW Subscription Status
- Examples for this Profile: Task/cow-coordination-task-example

You can also check for usages in the FHIR IG Statistics
