Aside: apparently the FHIR approach to representing things like 'no
known allergies' is to infer it by seeing if an allergies list is
empty or not. That sounds like a bad idea to me. If 'no known
allergies' is understood as a clinically meaningful statement made by
e.g. a GP (based on reliable knowledge about the patient), checking
for a list being empty in some EMR system isn't at all the same
thing. All that latter does is establish that no allergies have been
recorded on this particular system.
Well, that would be a bad idea. But that's ok because that's not what
we do ;-)
good to know. I have incorrectly remembered the content of FHIR
discussions on this topic.
There is a specific flag on list for noting the clinically meaningful
statement, but what we've found is that almost all systems treat the
statement of no allergies in an allergy record as an explicit statement
that sounds right.
Btw, I don't think that the statement of no allergy is a case of a
negation statement
Is there any online summary of how negations, exclusions etc are
understood in FHIR?
