Thank you for your email. You are correct in your assertion. I have felt that
this is not summary data and as an Entry should go in an archetype called
questionnaire.
Archetype can then have a question and an answer. Such data is usually derived
from the EHR in the long run - I call it cross sectional data - it is not
persistent as it is false the next day if they are diagnosed tomorrow.
Observation
concept = questionnaire item
Element "Do you have diabetes?" value BOOLEAN
You may have many of these - I believe processing will need to be undertaken by
the designer of the questionnaire - but these may with time become
standardised.
You could map the element term to the code for Diabetes Mellitus in SNOMED.
How does this sound?
