HL7 recognizes that the antitrust laws were enacted to promote fairness in competition and, as such, supports laws against monopoly and restraints of trade and their enforcement.

TopicHTA and TSMGContinued from previousCarol

Membership established through changes in TSMG.  GOM requires some examination for changes.  Discussion deferred to future HTA meeting. 

Roel notes there is a tight turnaround between the end of the weekly TSMG meeting and this meeting timing that provides some challenges.

UTG/THO Update

ContinuousJess and Reuben

  • Analysis of HTA External Terminology pages – Link to Google Sheet
    • For discussion: addressing the external terminology pages which do not use the new template (62 of 93 / 67%)
  • Call to co-chairs to review code systems was made at the beginning of October and they have until the end of October to make requests for code systems to be retained in THO that have not been previously registered with the HTA. The list is shown here 
    • Responses to date include 
    • From AMS
      • This note is written in response to the TSMG request that workgroups review the list of code systems not managed by the HTA and identify from that list the code systems which should be retained and brought under the HTA's management. The Public Health workgroup has identified the following codes systems from the list that should be retained:


        Industry CDC Census 2010




        Occupation CDC Census 2010




        Codes for Race, authored and maintained by the CDC



        The list is still under review; it is possible that additional code systems will be identified at a later date. We will also review the metadata associated with each code system and update the metadata as needed. 

        The PHWG agenda for 10/21/2021 includes further discussion on this topic with a primary focus on ODH vocabulary. If a member of the TSMG or HTA is able to join our call (details can be found here) it would be very much appreciated. Thanks.

We are almost through the core principles.
