Dear all

SNOMED International are currently considering moving towards more frequent delivery of the SNOMED CT International Release package.

The move towards more frequent releases of SNOMED CT would realise several benefits, including:

  • The potential to be able to get content changes into the terminology in a shorter time frame.
  • The fostering of better interoperability, as a result of entities being able to consume release content that is more aligned with other organisations.
  • The prevention of circular dependencies that occur in longer projects, due to the move towards smaller, more manageable authoring projects.
  • More automated validation services, as a result of the inherent removal of the Alpha and Beta stages in the Release cycle.

The only significant change for most users will be the removal of Delta files from SNOMED CT release packages. They will instead be available via an on-demand service, which will allow the creation of bespoke Delta files, relative to a given previously published release. This will inherently mean that some Delta files may start to contain multiple effectiveTimes.

We would therefore encourage any users who feel like they might have feedback on this proposal to complete the following survey:

If you would like your feedback to be considered in the discussions please complete the survey as soon as possible, and certainly before the 30th April 2019.

Thank you very much in advance for your time,

Kind regards

In addition to the twice annual release of the SNOMED CT International edition, SNOMED International produces and releases a number of SNOMED CT derivative products which are released on a 6 monthly cycle, and in line with the SNOMED CT International Edition release.
Recent work to evaluate the use of these products among our different stakeholder groups has indicated that current usage of the range of derivative products is comparatively low due to stakeholder challenges with consuming a twice annual release.  This, coupled with our efforts to better utilize the organization’s content and release resources, has led SNOMED International to the decision to move to an annual release cycle for these products, following an established schedule in line with the January or July International Edition release.

Please contact for additional information if required.

Kind regards
