1. Creating the Form

In order for a form to be used consistently across the healthcare enterprise it must be defined and then stored in a repository.

The US National Laboratory of Medicine - FHIR Tools has several tools to support the curation of forms and a repository of forms.

The NLM Form Builder provides an web app which can be used to generate FHIR Questionnaires. For example:

1. Open the form NLM Form Builder
2. Select Start with an existing form
3. Then select Import from LOINC, enter Vital Signs and select the entry with 74728-7 LOINC code.
4. When the top form is displayed, click on Edit Questions which displays the questions the forms contains.

This can then be stored on a central server to be shared with users. In the NLM Form Builder this can be done by using the export function. The address of the UKCore Hackathon Server is

https://3cdzg7kbj4.execute-api.eu-west-2.amazonaws.com/poc/events/FHIR/R4

This server will make a few alterations to the submitted Questionnaire for technical reasons. The most important change is it will create a Questionnaire.url if one is not supplied from the Questionnaire.code. For the Vital signs, weight, height, head circumference, oximetry, BMI, and BSA panel - HL7.CCDAr1.1 from the LOINC server, it will use the code 74728-7 and create a url of:

https://example.fhir.nhs.uk/Questionnaire/74728-7

This url is used in FHIR QuestionnaireResponse and Validation.

To find, update, add or delete the Questionnaire please see Demonstration Server

This Questionnaire can now be used by FHIR Validation to check FHIR QuestionnaireResponse resources.
