Conditions for "unanswered" questions should not be generated

[noemide]

Describe the bug
Currently, if questions about the presence of a condition (e.g. chronic lung diseases) are not answered at all, it is still exported without any verification status. Since those conditions are typically interpreted as being present, this leads to false information being exported.

To Reproduce
Export empty for unaswered questions about preexisting Conditions.

Expected behavior
For unanswered questions, no Conditions should be exported.

Thank you for your report. I will have a closer look and come back to you.

@noemide Actually, I had a quite similar question this very morning which I posted on Zulip (https://chat.fhir.org/#narrow/stream/179183-german-%28d-a-ch%29/topic/GECCO-Datensatz/near/224294828) but have not received an answer yet...

I do not get the differentiation between unknown and not answered.

Why not assuming any unanswered field as unknown, and why not exclusively exporting only known answers like yes/no?

[holger-stenzhorn]

@makampf Well, technically, if you do not answer a question at all then you do not provide any information but if you answer that you do not know then you provide at least that information... 🙂 How relevant this is in the end and how this should be "modeled" in FHIR is another question. 🤷‍♂️

The CodeSystem DataAbsentReason describes the differences. (and also possible different codings)
As @holger-stenzhorn already said, the relevance is indeed questionable.

I wondered about the relevance in cohort identification an thats actually different level of questionable relevance :D
