Structured Data Capture, published by HL7 International / FHIR Infrastructure. This guide is not an authorized publication; it is the continuous build for version 4.0.0-ballot built by the FHIR (HL7® FHIR® Standard) CI Build.

Resource Profile: Populatable Questionnaire - Observation

Official URL: http://hl7.org/fhir/uv/sdc/StructureDefinition/sdc-questionnaire-pop-obsn Version: 4.0.0-ballot
Standards status: Trial-use Maturity Level: 4 Computable Name: SDCQuestionnairePopulateObservation
Other Identifiers: OID:2.16.840.1.113883.4.642.40.17.42.46

Defines elements that support auto-population and pre-population of questionnaires using the Observation-based population mechanism

Scope and Usage

This profile adds additional constraints and extensions to the base SDC Base Questionnaire Profile that support generating and potentially partially populating a questionnaire response using existing FHIR resource data. This profile identifies which core elements and extensions must be supported when using the Observation-based population mechanism and highlights other elements that, while not required, may be relevant to the questionnaire response population use-case. Further information on how this use-case is implemented as well as guidance on the elements and extensions included in the profile can be found on the Questionnaire Population page.
