  • Revised Autumn 2020 Schedule for UK SNOMED Releases

    Published: August 2020

    Dear Colleague,

    The next scheduled combined releases of the SNOMED UK Clinical and Drug Extensions, on 07 October, were both planned to be “major releases” involving very substantial changes imposed by rebasing the content on the latest July 2020 SNOMED CT International Edition.

    Unfortunately, technical teething issues with an upgrade to our NHS Digital SNOMED CT authoring platform have eaten too far into our authoring contingency time. We have, therefore, reluctantly taken the decision to descope that “content rebasing” element from both 07 October 2020 releases.

    Whilst there will still be 07 October 2020 releases for both extensions, they are both now descoped to being only a 30.2.0 “minor release”: both will remain based on the July 2019 SNOMED CT International Edition (as for the existing 30.0.0 releases). The SNOMED CT UK Clinical Extension will add only fairly modest quantities of new UK content, some of which will be specific to managing COVID-19 but most of which will not. The 30.2.0 SNOMED CT UK Drug Extension release will be a normal four-weekly release , following the immediately preceding release of 30.1.0 SNOMED CT UK Drug Extension scheduled for 9 September 2020.

    The originally planned “major release” element will, therefore, now occur at a new, previously unscheduled combined release on 04 November 2020, in which all content to date in both extensions will finally become simultaneously rebased to the July 2020 SNOMED CT International Edition. Deferring until the already scheduled 02 December 2020 release date was considered, but many suppliers had previously expressed a strong preference against “major releases” in December 2020.

    The  revised release schedule to the end of 2020 is, therefore:

    07 October 2020

    TRUD Version 30.2.0
    EffectiveTime 20200930
    Base Content July 2019 SNOMED CT International Edition (the same as 30.0.0 12 August 2020)

    • Any requested new COVID-19 content (as per a microrelease)

  • Known issues with the Module Dependency Refset (MDR) file

    Published: August 2020

    Dear Colleague,

    The 15 April 2020 MDR release included some off-specification duplicate rows in which the same ID and effectiveTime appeared twice, but with different data. Attempts to build the standard unique composite key on {ID, effectiveTime} on the FULL data as distributed will therefore fail.

    The IDs and effectiveTimes involved are:

    • f0658b79-0cbc-116a-e044-0003ba13161a             20200415
    • f0658b79-0cbd-116a-e044-0003ba13161a            20200415

    This technical error has subsequently been published in all FULL file distributions made since 15 April.

    The error can not be removed by means of a further Delta, but is scheduled to be expunged from the distributed FULL files from the 7 October 2020 release.

    For those affected by the error, a range of mitigations exist:

    1. Do not load (or index) the MDR content at all, if it is not in fact required by your application.
    2. Depart from the specification and apply a non-unique index over {ID, effectiveTime}. Extraction of the latest snapshot of the MDR would not be adversely affected.
    3. Manually delete the erroneous data from the FULL table, before then proceeding with the usual unique indexation:

    DELETE FROM snomed.rf2_ssrefset_full
    WHERE ID IN (‘f0658b79-0cbc-116a-e044-0003ba13161a’,’f0658b79-0cbd-116a-e044-0003ba13161a’)
    AND effectiveTime = ‘20200415’
    AND linkedString1 = ‘20200401’;

        4. (From 7 October release) Replace your current cumulative FULL data for this table with a copy of a newer distribution, from which the error has  already been removed at source.

    Finally, NHS Digital would welcome more direct engagement with those who encounter this error, and especially those whose applications actively use the MDR data. We are keen to understand user expectations and experiences with it to date, and discuss other known MDR historical issues and plans for its future development.

    Kind regards,
