Advanced intersection

[rossjones]

Originally from #13

Intersections of drugs in particular can be more complicated
For example
Allergy = Co-Amoxiclav
Should trigger an alert if drug ==Any penicillin
Might trigger an alert if drug==any cephlasporin or any carbapenem

[rossjones]

We may need some special form of API for keyword expansion, so we can easily determine all penicillin drug names, for instance.

We could implement this with vars and phrases like...

when "allergies.name" intersections "@paracetamol_names"

but this is a bit specific and would require a lot of rules.

Need to think about this some more.

For drugs at least I would consider meta-categories/groups?
e.g
All penicillins belong to group X (trivial to do for a clinician or by scraping the BNF ala OPENBNF)
Repeat

This is another case of openhealthcare/elcid#447 - taxonomies for coded lists.
The short term thing to do is allow arrays as variables and have user defined ones for the subset that are actually in use.

Mediumer term, we need coordinated taxonomies for coded data, which should be a coherent approach across all of our projects.

Perhaps we need something that provides this as a service?
https://github.com/openhealthcare/dmdd or an elixir version?
I'd want to be able to answer taxonomical questions, or at least ask for a point in the graph and get all subnodes for a given dimension.

Maybe we want a graph database + API + some ETL for DMDD/SNOMED CT/TRUD/ICD10/Something else (this is not currently my area of expertise)

+1 for Elixir. Unsure about a graphdb, or whether to use mnesia/digraph. We probably do want a DAG though to represent it.

[davidmiller]

mnesia + / or digraph !

Looks like it could work :)

Maybe that can be a project to hack on at Elixirconf.eu ?
