## Resource Profile: CRD Questionnaire Task

Official URL: http://hl7.org/fhir/us/davinci-crd/StructureDefinition/profile-taskquestionnaire | Version: 2.2.1 | Highlight text changes?
Standards status: Trial-use Active as of 2026-03-26 | Maturity Level: 1 | Computable Name: CRDTaskQuestionnaire
Other Identifiers: OID:2.16.840.1.113883.4.642.40.18.42.18

This profile specifies constraints on the Task resource to support requests for form (Questionnaire) completion.

### Usage

This profile on Task allows a response CDS Hooks Card to request a user to fill out a Questionnaire (pointed to as a Task.input). It supports the process described in the Deferring Card Actions portion of the spec.

Information provided in Must Support elements will commonly be required for CRD Servers to perform coverage requirements discovery. </br>
