Topic: FHIR Messaging Event types?
Andre Guerreiro (Apr 21 2019 at 23:21):
Hi,
I'm trying to make sense on how the concept of event types as defined on HL7 v2 (for ex ADT04, ADT08,ADT34 all meant a particular type of event) is represented on FHIR. I know that inside the message bundle I have the message header which inside has the event code but where do I find the list of defined event codes? Thanks

There aren't any standard event codes or messages in FHIR right now. So far, those who are doing messaging are essentially doing custom server-specific interfaces and there hasn't been much interest in standardizing that part of FHIR from the implementer community.

The urgency to define something in this area is increasing given the increase in the number of FHIR messaging projects and v2-to-FHIR mappings. For the v2-to-FHIR scenario you could use http://terminology.hl7.org/CodeSystem/v2-0003 (v2 trigger event type code) as a coding system.

I expect this will (eventually) be part of the v2-to-FHIR project (https://confluence.hl7.org/display/OO/2-To-FHIR+Project). I folks have thoughts on the best way to document this, please add to your thoughts to the Confluence page (I'll also link this thread to the Confluence page for future reference).

Wanted to jump in here- the message-events ValueSet is listed as Normative from v4 FHIR release (http://hl7.org/fhir/valueset-message-events.html). However, "this value set contains 0 concepts." What do we make of this? I would be expecting what the OP was saying, example Code = ADT04, System = HL7 v2, Display = Patient Registration.
Is this ValueSet (and associated CodeSet) supposed to be empty as a Normative standard or is this some weird mistake? Thanks in advance.
Lloyd McKenzie (May 28 2019 at 17:22):
We probably shouldn't have marked it as normative, but yes, it's empty on purpose. So far the small portion of the FHIR community using messaging has not shown any interest in trying to standardize event codes. So at the moment, each messaging community defines their own code system(do) and codes.
