V2.9 ballot reconciliation
In HL7 table type the values are HL7 content. these tables are clinical content and many countries now want to convert this to SNOMED CT content. This requires changing from HL7 type to User Defined table type. This has the potential to break the backward compatibility rules. It is allowed to extend a table but not to redefine what is in there.
It was agreed that we would like to do this but it would break the existing rules of V2 and we are therefore inhibited from achieving this requirement. Consideration was given to the introduction of a new feature in V2 but this could not be added in the current ballot cycle. A solution for the future will be considered. FHIR is an alternative.
There is currently no tooling that supports enumeration of value set content without a table. This request is to use a v3 value set and in the code system property they want to list the version 3 code system which requires a neumonic rather than a table number.
What would this type of 'table' be as the content is external to the v2 process but it is still owned within the HL7 product family. there is a need to publish the content but our tooling has no way to undertake this publishing process. this requires a 'table number' where the values come from a code system in e.g. V3. It behaves like an external table but is really internal to HL7. There is also the issue of how to not reference the table by number, but rather a neumonic from the original product family held in the 393 table. Table 2C can enumerate the values but it is preferred not to do tht as there could be maintenance issues over time.
HL7 table in V2 means this is an HL7 V2 table but external tables could also be HL7 but external to the V2 management process.
We would need to create the value set in the V2 tooling using the V3 value set as the source.
Action: we will not eneumerate it in the V2 specification but the content will need to be published somewhere - there could be a 1 year gap between publishing the V2 reference and the value set becoming available through publishing next time there is a V3 normalised ballot. In the longer term the reference could be UTG.
|Meeting schedule||It was agreed to continue meeting in this quarter at the next meeting. The next meeting is after ballot and will be likely to be required - Vocab will host.|
