B.4.0 Structured Data Capture Questionnaire Design

B.4.0.1 Scope and Usage

This profile sets expectations for use of the Questionnaire resource within the Structured Data Capture implementation guide. This includes identifying which core elements and extensions must be supported.

For the purposes of this profile, Supported means that clients SHALL be capable of processing the element/extension and use the information to control the display and information capture associated with the Questionnaire. It means that servers SHALL be capable of persisting those elements and returning them in response to requests.

B.4.0.2 Boundaries and Relationships

This profile relies on the use of a number of other profiles, some required, others available for use "when necessary":

  • questionnaire-extensions which defines a number of less common properties for questionnaire, group and question, several of which are mandated for this profile.
  • element-extensions which defines extensions describing constraints on the values for data elements. There are used here to constrain the allowed values for questions.
  • iso-21090 provides extensions for strings allowing the conveying of language and translation extensions which may be relevant in some environment
  • rendering-extensions which defines properties to give fine-grained control over how questions, labels and other strings are rendered

B.4.0.3 Content

Profiles:
SDC-QuestionnaireDefines how Questionnaire is used to reflect form definitions to be used within the ONC's Structured Data Capture standard.
Extensions:
sdc-questionnaire-endpointWhere to send answers :

The base URL for the server to which questionnaire response associated with this questionnaire should be submitted.

sdc-questionnaire-optionalDisplayCan suppress from display to user :

If set to true, it means that the system displaying the form (or the individual encoding the form for data capture) can choose to omit the item from display to the user.

sdc-questionnaire-provenanceSignatureRequredIs associated Provenance needed? :

If true, indicates that QuestionnaireResponse instances created against this questionnaire must have an associated Provenance record.

Examples:
SDC - Combination

Set of several examples - medication, AHRQ and NCI forms

SDC-Pathology

Cancer pathology questionnaire with flow-control extensions

SDC-LOINC AHRQ

LOINC perspective on the AHRQ form found in the SDC - Combination set of questionnaires

SDC-LOINC USSG Family History

LOINC US Surgeon General family history including data elements & value sets. Note: This example isn't strictly valid against SDC as data elements do not have definitions and don't include mappings to SDC-approved specificaitons for auto-population

B.4.0.4 Language and translations

In some environments, it may be necessary for a questionnaire to support multiple languages. The rendering tool would select the appropriate language based on a configuration setting, or perhaps would display all available languages and the user would read the one they are familiar with. Systems MAY choose to provide support for identifying language and translations. If they do, they MAY do so using the generic language and translation extensions FHIR defines based on the ISO21090 data type specification:

These extensions can be used on absolutely any string element on Questionnaire, ValueSet, one of the data types or any other resource. The base string should be the primary language of the questionnaire. It is what will be rendered by systems that do not support the translation extension or by systems whose language preference is other than one of the languages provided.

The ISO 19763 specification permits declaring language on questionnaire titles, descriptions, display names for codes and many other strings. It also supports capturing multiple variants of these strings with distinct languages. These capabilities can be mirrored using the above extensions.

An alternative is to define an extension to the Questionnaire providing a pointer to an externally maintained set of extensions. This approach allows the translations to be maintained independently of the resource which has both positive and negative impacts, particularly with respect to resource signature.

Open Issue: Should this profile define such an extension and/or a resource for managing such translations?

Usage note: every effort has been made to ensure that the examples are correct and useful, but they are not a normative part of the specification.
