Topic: SDC questionnaire advanced rendering

Hello, I see in one of the SDC examples for questionnaire / advanced rendering (R4) there is a _text attribute in addition to a text attribute for the items. Is this intentional? Trying to work out what to do if I want to apply the http://hl7.org/fhir/R4/extension-rendering-xhtml.html extension to the text element.

Hi! Do you know if we can extend itemControl extension to control rendering of question input?
Fhir docs say:
Terminology Binding The codes SHALL be taken from Questionnaire Item UI Control Codes; other codes may be used where these codes are not suitable
So if text-box value is not enough, can we add additional value?

@Matthew Koch Yes. Because in JSON representation the "text" attribute value is just a string, "_text" is the place to put extensions. You might have both "text" and "_text".
Paul Lynch (Jan 21 2020 at 16:59):
@Yuriy Khamzyaev Yes, since it is extensible you can add other values if the existing ones are not suitable, though it is unlikely anyone else will understand the values you add. It might be better, if you think there might be a general need for another value, to discuss here whether it should be added to the specification.

Thanks I ended up figuring this out after doing some more reading. I should have followed up here!

FYI, there is a "questionnaire" stream also.

You are free to define codes in a supplementary code system and send them in the itemControl extension if the ones defined don't cover what you need. However, you can't expect other systems that comply with SDC to understand or adhere to those codes. If you have a requirement that's general purpose, you might want to submit a change proposal so your needs can be represented in the official value set @Yuriy Khamzyaev
Yuriy Khamzyaev (Jan 21 2020 at 18:39):
@Lloyd McKenzie @Paul Lynch Thanks a lot for info! Yeah, we don't need this value to be general purpose yet, but it could become in future.
Lloyd McKenzie (Jan 21 2020 at 19:18):
The question isn't so much whether you need the value to be general purpose as whether you think the value you need is likely to be relevant to a decent number of others in the community
