Consider restructuring comorbidity logical model #28

Closed ElliotSilver closed 3 years ago

Switch to using codes for the condition and codes for whether it is present. (supporting y/n/unk)

What is the impact on questionnaire and resource mapping?

(Check out Logica -- I think they are doing it this way. Also review recent discussion on Zulip https://chat.fhir.org/#narrow/stream/179166-implementers/topic/Representing.20a.20Comorbidity)

Mostly implemented in questionnaire and logical model. Created issue #74 for enabling pregnancy trimester dependent on pregnancy comorbidity. Consistent with group consensus, did not add y/n/unk: a comorbidity is affirmatively asserted if present in the list, no assumption can be made about the comorbidity if absent from the list ("known, not applicable," "unknown if applicable," and "co-morbidity not in answer value set when asked" are some potential reasons for omitting). Although this may be limiting, it is believed other approaches have other shortcomings.
