Hi Pablo,

The modeller’s dilemma!

If you make clinical synopsis more specific then how many variations will there 
be in the end? We will end up with zillions of variations of all the generic 
archetypes which will be an absolute governance nightmare.

I would prefer to see the queryable filter made at the template level – even as 
simply as using the COMPOSITION.encounter inside a ‘Psychotherapy consultation’ 
template. Use that template within all of the Psychotherapy consults for that 
app consistently.

Then query for the EVALUATION.clinical_synopsis across all templates that 
contain the COMPOSITION.encounter which has specifically been renamed to 
‘Psychotherapy consultation’.

Regards

Heather

Subject: Modeling generic concepts, considerations for querying

Hi all,

I'm working with the clinical synopsis archetype, using it to model very open 
psychotherapy notes. The difference of that archetype from, for instance, blood 
pressure, triage, problem/diagnosis, is these archetypes are more or less very 
specific concepts, while synopsis might be used in many contexts, by different 
specialties, to save different kinds of data. The synopsis itself is a very 
generic concept.

Considering querying for a synopsis, I think queries should consider the 
context, not only the archetype id. For instance if I want the psychotherapy 
notes instead of other kinds of clinical synopsis, some extra data should be 
given in the query.

I can see two ways of doing this, with more 1. specific archetypes or 2. using 
templates to filter the query results. 1. means the synopsis archetype might  
be specialized to synopsis-psychotherapy, so queries can use that new archetype 
id. 2. at the template level using the synopsis archetype, and the template is 
for psychotherapy. This implies the template id should be used on the query as 
context/filter.

What alternative do clinical modelers see as more correct?

I like specializing archetypes because we can keep queries simple, but we might 
end up with a lot of archetypes. Using templates makes queries more complex, 
but we don't need more archetypes for specializations.

Thanks!

PS: please let me know if this doesn't make sense :)
