FHIR Questionnaire to Aidbox Forms and back conversion

You can use Aidbox to convert

  • FHIR Questionnaires to Aidbox Forms

  • Aidbox Forms to FHIR Questionnaires (with some limitations)

  • SDCDocument to FHIR QuestionnaireResponse resource.

You can use Aidbox Form API

Optional features

Aidbox Forms supports

  • automatic Form convertion to Questionnaire resource on Aidbox startup.

  • automatic SDCDocument convertion to QuestionnaireResponse resource on SDCDocument save.

  • Form rules conversion to human-readable description.

These features can be configured via api-constructor in zen-project.

You need to configure your aidbox/system with sdc-service and it's configuration.

Example:

Your zen-project entrypoint namespace (box.edn for example)

 box
 {:zen/tags #{aidbox/system}
  :zen/desc "test server"
  :services {:sdc sdc-service}}

Forms conversion on startup

For forms conversion you should set [:conversion :convert-forms-on-start] property to true

Example:

 sdc-service
 {:zen/tags   #{aidbox/service}
  :engine     aidbox.sdc/service
  :conversion {:convert-forms-on-start {:enabled true}}

You need to restart aidbox to take effect of changed configuration

Document conversion on save

For Document conversion you should set [:conversion :convert-doc-on-save] property to true

Example:

 sdc-service
 {:zen/tags   #{aidbox/service}
  :engine     aidbox.sdc/service
  :conversion {:convert-doc-on-save {:enabled true}}

You need to restart aidbox to take effect of changed configuration

After that - every document changes will be reflected in QuestionnaireResponse resources.

NOTE: id of converted QuestionnaireResponse will be the same as id of SDCDocument.

Form rules conversion to human-readable description.

You can enable aidbox.sdc/rules conversion to human friendly text while converting Form or Document.

Because Questionnaire and QuestionnaireResponse structures doesn't have place where to store such data We define 2 extra profiles for these resource-types.

You can enable this feature by adding:

  • zen.fhir and hl7-fhir-r4-core dependecies to your zen-package.edn

  • aidbox.sdc.extra import to your entrypoint namespace

  • :describe-rules key to service configuration or RPC call

Example:

zen-package.edn

{:deps {zen.fhir "https://github.com/zen-fhir/zen.fhir.git"
        hl7-fhir-r4-core "https://github.com/zen-fhir/hl7-fhir-r4-core.git"}}

box.edn

Assume that box.edn is your zen-project entrypoint namespace

{ns box
 import #{aidbox.sdc.extra}

 ...

 sdc-service
 {:zen/tags   #{aidbox/service}
  :engine     aidbox.sdc/service
  :conversion {:convert-doc-on-save {:enabled true
                                     :describe-rules true}}
 }

When feature is enabled you will see additional data in Questionnaire and QuestionnaireResponse after converting Forms and Documents with rules.

In Aidbox format you will see rule-description field.

GET /Questionnaire/q1

resourceType: Questionnaire
item:
  - linkId: 1
    text: BMI
    rule-description: "A / B * B\n\n where\n* A - body weight\n* B - body height"

In FHIR format you will see an extension with valueMarkdown

GET /fhir/Questionnaire/q1

resourceType: Questionnaire
item:
  - linkId: 1
    text: BMI
    extension:
       - url: urn:fhir:extension:sdc-questionnaire-ruleDescription
         valueMarkdown: A / B * B\n\n where\n* A - body weight\n* B - body height

Include score value in QuestionnaireResponse

aidbox.sdc/choice field can have additional field called :score that have no represantation in QuestionnaireResponse.

You can include this field in conversion by adding:

  • zen.fhir and hl7-fhir-r4-core dependecies to your zen-package.edn

  • aidbox.sdc.extra import to your entrypoint namespace

  • :include-scores key to service configuration or RPC call

Example:

zen-package.edn

{:deps {zen.fhir "https://github.com/zen-fhir/zen.fhir.git"
        hl7-fhir-r4-core "https://github.com/zen-fhir/hl7-fhir-r4-core.git"}}

box.edn

Assume that box.edn is your zen-project entrypoint namespace

{ns box
 import #{aidbox.sdc.extra}

 ...

 sdc-service
 {:zen/tags   #{aidbox/service}
  :engine     aidbox.sdc/service
  :conversion {:convert-doc-on-save {:enabled true
                                     :include-scores true}}
 }

When feature is enabled you will see additional data in QuestionnaireResponse after converting Documents with scores.

In Aidbox format you will see score field.

GET /QuestionnaireResponse/q1

resourceType: QuestionnaireResponse

  - linkId: 69734-2
   	text: Trouble relaxing

            code: LA6571-9
            display: Nearly every day
            score: 3
