Teleconference 2020-04-01

Old FHIR Accelerator Home

Suggest we produce a very short section on the HTA to go onto the FHIR Accelerator information page.  Julie James  will follow up to get something on this page for HTA

Co-chair handbook Co-Chair Handbook - nothing at all about terminology or vocabulary - and therefore about Vocab facilitation.  

Julie James will reach out to PIC and ask to have some mention of terminology/vocabulary - IF the Vocab WG would support that (Reuben to take this to Vocab WG and get back to Julie)

Motion: HTA recommends to the UTG removes the four NUBC code systems and the HPC (HCPCS) code system from the first release of the UTG.  The content should be stored but not published.

Proposed: CM; second: SM - carried unanimously.

Jessica Bota will communicate this to Ted Klein to action in the UTG.

We discussed that the HCPCS code system is a grey area because it is a CMS/HIPAA mandated code system based on the CPT4 codes from AMA, but for now, it will not in UTG.

Reuben Daniels is dealing with some queries from Ted regarding FHIR code systems.  We are likely to see some email traffic on the HTA list for this.

STILL OPEN: Other ISO standards to check

 The current ask within BCP47 is

• Davera Gabriel will look up more information about BCP-47 (a document authored by the IETF trust) for language codes in the US Core FHIR IG.  Davera will check if this is actually a "nested reference" and is actually a syntax using ISO

It still unclear what the implications of the difference are. The applicable section to review is "2.2 Language Subtag Sources and Interpretation" in https://tools.ietf.org/html/bcp47. Davera will look at the US Core FHIR IG to determine if they are referencing the ISO set for Language Codes and/or another set or a syntax

Previous commentary is shown below:

Process comment: Meeting minutes from meeting in which these items were originally discussed were updated after the fact. Requesting that assignments are tagged with a user name so users can be notified. 

• FHIR also uses the IANA Time Zones https://www.iana.org/time-zones
• Davera Gabriel will look up more information about BCP-47 (a document authored by the IETF trust) for language codes in the US Core FHIR IG.  Davera will check if this is actually a "nested reference" and is actually a syntax using ISO codes https://tools.ietf.org/html/bcp47
• (follow-up from Davera) Appologies for needing to step away & then not getting back to this in the meeting.  In the document linked above is the answer to the question.  On Page 8, under the section: "2.2. Language Subtag Sources and Interpretation" there is an explanation of the name spacing used to construct the BCP-47 "tags."  It is my read that the answer to the question as posited is a hybrid of the two options you propose in your question.  There is structure within the tags, but Im not sure that includes your posited definition of "syntax."  One would have to parse the tags to derive syntax, but as this is standard it could be done.  As such, what I intended to do in the meeting is discuss what was meant by question created the amended meeting minutes and NOT in the original meeting minutes: "Davera will check if this is actually a "nested reference" and is actually a syntax using ISO codes" to see if the tag / subtag structure fit your intended question definition of "syntax."  In practice, the subtags are intended to designate corollaries to portions of ISO 639.x designating spoken or written languages. 
• I would further suggest we consult with the folks that suggested the use of BCP-47 as to their intentions.  I'd be very interested to learn whether they are interested in capturing a written versus spoken language.  My hunch is that there's a much simpler explanation than that, in which case splitting the BCP-47 tags is not implied, nor necessary for their use case, and if so:  we are overthinking a bit
