Use R5 of Fhir

[DaniArj1980]

Good morning, Would there be a way to modify the code so that the questionnaires make use of the configuration of the R5 version of Fhir? Greetings, thank you.

lforms does support R5, except for 'disabledDisplay' and answerConstraint=optionsOrType. What are you having trouble with?

[DaniArj1980]

Thank you very much for the response, my idea is to use the functionality made in the formbuilder demo at the url: https://lhcforms.nlm.nih.gov/lhcforms. I don't know if I need to make any configuration to use a version R5 questionnaire. In this case I would like to expand because I don't know if a questionnaire items of the attachment type is made, to add a file to the questionnaire.

Greetings, thank you

https://lhcforms.nlm.nih.gov/lhcforms is actually the demo of LHC-Forms (not the formbuilder, which is at https://formbuilder.nlm.nih.gov), but yes, you should be able to load an R5 Questionnaire there using the "Load From File" button, and we do support Questionnaire items of type attachment.

[DaniArj1980]

Thanks, I would have to make some type of modification to the demo to be able to use R5, on a local server?

[plynchnlm]

There should be no need to modify lforms (this package) to use R5. Which demo are you referring to? Some of our demos are probably in need of an update.

[DaniArj1980]

Yes, I refer to https://lhcforms.nlm.nih.gov/lhcforms

[plynchnlm]

Okay, that demo is not open-source, because it is a part of the project website. What part of that demo is of interest to you? I assume you probably don't want the same sidebar. Would this demo, which is one of the demos on the lforms documentation site, be a good starting point for you?

[DaniArj1980]

Yes, of course. I would be interested in both the formbuilder and the formviewer for questionnaire in R5

[plynchnlm]

The formbuilder is a separate package, https://github.com/LHNCBC/formbuilder-lhcforms, which is also on-line as a website, https://formbuilder.nlm.nih.gov/. However, it does not have R5 support yet.

[DaniArj1980]

And could you use this functionality for a Fhir R5 service? If so, what changes should I make? because it gives me problems for the choise types since in R5, they no longer exist, it would be the coding types

[plynchnlm]

The formbuidler's UI is still focused on R4, and only does lists for types choice and open-choice. However, if that limitation is acceptable, you could use lforms to convert the formbuilder's R4 output to R5 (so the types of the lists would be "coding").

[DaniArj1980]

Would this be very complex? Would I have to modify a code? I already have the lform library modified?

[plynchnlm]

Well, I am not clear on what you are doing. If you are going to use the formbuilder, you would probably want to modify that code to provide an option to export the built form in R5 format, which you could create using this lforms package, by importing the R4 version and exporting it in R5, using the documented FHIR APIs.

Hello, I have managed to solve the choise problem for R5, but when I try to make a post, I get the following error:

Error: Question with linkId '2561826271176' contains enableWhen pointing to a question with linkId 'undefined' that does not exist.

This occurs when calling the function
LForms.Util.convertFHIRQuestionnaireToLForms(fhirQ),'R5')

[plynchnlm]

That error indicates that there is a problem with the Questionnaire definition. It is saying that the question that has linkId 2561826271176 has an enableWhen section that that is missing a linkId (in the "enableWhen.question" field).
