Topic: searching for codes by display string
Aziz Boxwala (May 06 2019 at 22:50):
I looked and couldn't find an operation for finding codes from a code system that matches the code text (display). The closest one is $find-matches in CodeSystem, but that doesn't support partial string matching. We're trying to implement an operation for look ahead searching. Searching in CPT for "append" should at least find "appendectomy".
I want to confirm that I didn't miss anything. And if there isn't such an operation, whether it might be useful to incorporate that capability in a new operation or an existing operation.

You want the filter parameter of the $expand operation: /ValueSet/$expand?filter=text

Have a play with http://ontoserver.csiro.au/vstool - it provides an interactive environment for doing this with a number of different terminology servers

Thank you Michael.
Aziz Boxwala (May 07 2019 at 01:48):
@Michael Lawley Just tried it out. This is very helpful!

Can we have similar search operation for Coding Systems?
Jim Steel (May 07 2019 at 13:17):
You kind of get it for free if the CodeSystem has a valueSet property (Canonical reference to the value set with entire code system)
Michael Lawley (May 07 2019 at 14:04):
Exactly, a CodeSystem should have a value for CodeSystem.valueSet which implicitly defines the ValueSet that consists of all members of the CodeSystem.
It would be helpful if https://hl7.org/fhir/terminologies-systems.html also included this URI in the table(s) of code systems
Michael Lawley (May 07 2019 at 14:12):
Created GF#21640 for this
Jim Steel (May 07 2019 at 14:12):
I assume the CodeSystem.valueSet is encouraged not to be version-specific?
Aziz Boxwala (May 07 2019 at 16:46):
Before I go adrift again, can we use the $expand with a parameter to search by code, e.g., "loinc|1234-1". I understand there may be other operations, but I'd like to try to use one operation/endpoint to search for a concept by code or by text.
Jim Steel (May 07 2019 at 16:54):
That depends on the server implementation. Some servers will/do allow you to search by concept ID in the filter parameter
Peter Jordan (May 07 2019 at 18:29):
Mine now implements that for SNOMED CT (something to do during a meandering debate in a Board Meeting).
Jim Steel (May 07 2019 at 18:30):
Yes, Ontoserver does too (although not with the system| prefix
Aziz Boxwala (May 07 2019 at 22:37):
Thank you @Jim Steel and @Peter Jordan for the responses. We are building our own service, so we could use the approach.
Jim Steel (May 07 2019 at 23:15):
Best of luck! We'll look forward to maybe seeing you at a connectathon some time
Aziz Boxwala (May 07 2019 at 23:45):
I missed this one. When I am at the connectathon, I usually hang with CDS crowd. Last one was with genomics. See you, maybe, at the next one Jim.
