    UTL release schedule

    Dear all,

    In our previous newsletter we notified you of the publication of the latest iteration of the Unified test list v0.5.0 in human readable form on our Pathology and Diagnostics Kahootz site.

    The 139 new concepts in this 1st July release included a sample of microorganism nucleic acid SNOMED CT reporting concepts by presence of RNA/DNA, and a  sample of microorganism susceptibility to antimicrobial SNOMED CT reporting concepts.

    We would like to thank all those who attended the last PINUG meeting and subsequent UTL feedback workshop where we presented an overview of the UTL v0.5.0 release, received critical SME feedback on the release content and solicited interest from LIMS suppliers and providers in setting up focused sub groups to address questions relating our Pathology information standards in development (UTL, Units of measure and FHIR message specification).

    For those subscribed to TRUD you will have recently received a notification regarding the revised autumn 2020 schedule for UK SNOMED releases. As previously communicated, we have made the decision to align the release schedule of the UTL PaLM extension module on TRUD with the UK edition release schedule.

    The next UTL release (v0.6.0) will therefore coincide with the next major UK edition release, scheduled for the 4th November.

    Pathology Informatics National User group (PINUG)

    The Pathology Informatics National User Group (PINUG) aims to encourage a two-way dialogue between NHS Digital and other interested parties, allowing us to successfully align with all stakeholder group requirements.   

    The group meets every two months via MS Teams and consists of clinicians, diagnostic professionals and system suppliers.  The meetings are chaired by our lead clinician, who is a member of the Royal College of Pathologists (RCPath).

    The next PINUG is scheduled to take place on 8th September and will involve a discussion around the UTL v0.5.0 release feedback received at the UTL workshop in July, further information relating to the Proposed PINUG subgroups and recently updated education and training materials

    If you would like to be part of the PINUG please email us at Pathologyanddiagnostics@nhs.net for regular meeting invites and updates.

    Our work with the Professional Records Standards Body (PRSB)

    The Pathology business product team have recently undertaken a procurement exercise for the provision of Terminology skills and subject matter expertise to support strategic Pathology activities and are pleased to announce that the Professional Records Standards Body (PRSB) have been commissioned for this work.

    The PRSB will build and establish artefacts to showcase the feasibility of using our Pathology information standards in live systems, and will identify key stakeholders for 'first of type' demonstrators fit for submission to the Data coordination Board as evidence for replacement of the PBCL and replacement for EDIFACT Pathology messaging.

    UTL v0.5.0 Released

    Dear All,

    As Pathology stakeholders we recently notified you of the publication of the Unified Test List (UTL) V0.5.0. in human readable form on our Pathology and Diagnostics collaborative workspace.

    This release includes:

    • A sample of microorganism nucleic acid SNOMED CT reporting concepts by presence of RNA/DNA. These are specimen and technology/method neutral codes adhering to a proposed design decision to capture the postcoordinated and associated specimen and technology/method SNOMED CT concepts within the message specification. However, whether or not to add precoordinated specimens to microorganism nucleic acid SNOMED CT content in future UTL releases is still under consideration.
    • A sample of microorganism susceptibility to antimicrobial SNOMED CT reporting concepts. These are organism neutral codes adhering to a proposed design decision to capture the postcoordinated and associated microorganism SNOMED CT concept within the message specification.

    The columns for the attributes including substance, property and specimen are included purely for information. They are in development.  No use of these columns is planned at this stage.  They will ultimately be used to formally classify the SNOMED content using the observable entity concept model, where the attributes and corresponding values will be used to create the SNOMED CT machine readable description logic definitions.

    Please use the links below to access the updated UTL v0.5.0 documentation on our site:

    To provide feedback on the release as a whole, please contact us via our team mailbox: pathologyanddiagnostics@nhs.net  or alternatively contact us to request membership to our collaboration site in order to contribute to our UTL discussion forum 

    We offer a mechanism to allow users to easily send feedback or questions to us on a specific UTL concept, via a link on each item in the downloadable HTML-format review copy of the UTL. Please download the UTL v0.5.0 release and use the “feedback link” displayed against each line item in the HTML documents within the review package zip file.

    As a Pathology and Diagnostics stakeholder, you will have recently received an email with MS Teams meeting details for a UTL workshop scheduled to take place on the 15th July. The workshop will provide an opportunity for us to provide an overview of the v0.5.0 release and address any feedback received so far.

    Guidance for naming, coding and processing SARS-COV-2 Pathology Tests

    The Pathology Business Product team have been involved in reviewing and updating the guidance for the national naming, coding and processing of SARS-COV-2 Pathology tests which now contains additional information for Labs and LIMS on naming requestable and reportable items related  to SARS-COV-2 Testing. Working with the RCPath and the Pathology Standards Governance board (PSGB), a detailed set of requestable and reportable items has been created to help laboratories and LIMS suppliers define COVID19 related data items.

    Requesting and Test Sets (Panels)

    The team have been performing analysis on LIMS data extracts provided by Harrogate and Poole trusts and have also been analysing requesting data provided by a software supplier in the UK. These organisations have agreed to make the data available to the project, and to the wider stakeholder group, in support of the overall aims of the project.

    Based on the data provided so far, the team have developed a Requesting and Panels design options and decisions document and are beginning to engage with other labs in order to form a broader picture of requesting codes and practice across the country.

    Pathology Informatics National User Group (PINUG)

    The Pathology Informatics National User Group (PINUG) aims to encourage a two-way dialogue between NHS Digital and other interested parties, allowing us to successfully align with all stakeholder group requirements.   

    The group meets every two months via MS Teams and consists of clinicians, diagnostic professionals and system suppliers.  The meetings are chaired by our lead clinician, who is a member of the Royal College of Pathologists (RCPath).

    The forum allows us to provide parties with key updates and encourages stakeholders to share relevant news and information with us.

    We have recently scheduled a new series of bi-monthly PINUG meetings up until March 2021

    If you would like to be part of the PINUG please email us at Pathologyanddiagnostics@nhs.net for regular meeting invites and updates.

    Pathology Standards Governance board (PSGB)

    The Pathology Standards Governance Board (PSGB) is a cross-organisational expert group which provides oversight of the development, maintenance and release of the UTL with SNOMED CT concepts, including the Units of Measure

    (UoM) and pathology standard-related elements which are agreed by the board.

    The Governance Board comprises core members who oversee the development and maintenance of the UTL and extended members, who provide advice, support and feedback whilst keeping their organisations informed and facilitating

    endorsement where relevant.

    Throughout April and May the PSGB were instrumental in helping NHS Digital develop the guidance for the national naming, coding and processing of SARS-COV-2 Pathology tests.

    The next bi-monthly PSGB meeting is due to take place on 22nd July and will resume focus on the development of the UTL and associated Pathology information standards.

  • SNOMED CT UK Clinical Edition, RF2 for 17 June 2020

    The SNOMED CT UK Clinical Edition, RF2 for 17 June 2020 is now available for download from the following links:

    UK SNOMED CT Clinical Edition, RF2: Full, Snapshot & Delta download

    UK SNOMED CT Clinical Edition, RF2: Delta download

    The SNOMED CT UK Drug extension is not released as part of the SNOMED CT biannual release. SNOMED CT UK Drug Extension data is published on a four-weekly cycle within the "UK Drug Extension, RF2" sub pack on TRUD. Please review the associated documentation for more details.

    Release documentation is now only accessible on DELEN, at https://hscic.kahootz.com/connect.ti/t_c_home/view?objectId=16607376

    Please see the ‘Future release schedule’ section in this notice for important information about the release timetable and content for the remainder of the 2020 calendar year. Key points:

    • Larger August / October releases, to bring the UK Edition into alignment with the International Edition.
    • The possibility of moving to a more frequent release schedule in 2021.
    • Changes to the SNOMED CT UK Edition release subfolder structure.

    Important changes and information regarding this release:

    This is the fifth emergency COVID-19 “microrelease”. Changes are restricted to coding expressivity improvements urgently needed to manage the current pandemic. This very narrowed scope should reduce the “content update penalty” on product consumers, and so reduce barriers to the urgent deployment of the new content to the clinical frontline.

    This release remains based on the July 2018 International Edition.

    A new tranche of 11 COVID-19 codes are added relating to the current pandemic, in addition to those already released for that same purpose in the 28.1.1, 29.0.0 and 29.1.0 Emergency Releases of February and April 2020. The new codes are:

    1322781000000102       Severe acute respiratory syndrome coronavirus 2 antigen detection result positive (finding)

    1322791000000100       Severe acute respiratory syndrome coronavirus 2 antigen detection result negative (finding)

    1322801000000101       Severe acute respiratory syndrome coronavirus 2 antigen detection result indeterminate (finding)

    1322821000000105       Severe acute respiratory syndrome coronavirus 2 antigen detection result unknown (finding)

    1322831000000107       Severe acute respiratory syndrome coronavirus 2 immunoglobulin G detection result indeterminate (finding)

    1322841000000103       Severe acute respiratory syndrome coronavirus 2 immunoglobulin A detection result indeterminate (finding)

    1322851000000100       Severe acute respiratory syndrome coronavirus 2 immunoglobulin M detection result indeterminate (finding)

    1322871000000109       Severe acute respiratory syndrome coronavirus 2 antibody detection result positive (finding)

    1322891000000108       Severe acute respiratory syndrome coronavirus 2 antibody detection result negative (finding)

    1322901000000109       Severe acute respiratory syndrome coronavirus 2 antibody detection result indeterminate (finding)

    1322911000000106       Severe acute respiratory syndrome coronavirus 2 antibody detection result unknown (finding)

    In addition to the new COVID-19 concept codes above, the Preferred Term has been changed for the following already released non-COVID-19 concept code:

    1035881000000100

    Commission for Health Improvement Experience of Service Questionnaire self-report for 12-18 year olds item 3 score - I was treated well by the people who saw me (observable entity)

    PT

    Future release schedule

    Following a formal consultation with stakeholders, a schedule of releases for the remainder of the current calendar year is now published, including two much larger releases of non-COVID-19 content on 12 August and 7 October.  Between them, these two major releases will enable the publication of all newer versions of SNOMED International content released since July 2018, plus UK content deferred from the original 1 April release candidate, and some of the backlog of other new UK content requests unrelated to COVID-19. The Results of the formal consultation on the SNOMED CT UK Edition Release schedule are available on Delen.

    The schedule for these major releases through to the end of 2020 will be as follows:

    12 August

    TRUD Version  30.0.0 effectiveTime    20200805

    Base content:   July 2019 International Edition

    New content:    All UK content deferred from the 1 April release

                            Some additional non-COVID-19 content for the UK                         Any requested new COVID-19 content (as per a microrelease)                         Partial ICD10 and OPCS maps covering above new content                         “Light touch” update of refsets to align with new content

    7 October

    TRUD Version  31.0.0 effectiveTime    20200930

    Base content:   July 2020 International Edition

    New content:    Some additional non-COVID-19 content for the UK                         Any requested new COVID-19 content (as per a microrelease)                         Full ICD10 and OPCS maps covering above new content                         Full update of refsets to align with new content

    2 December

    TRUD Version  31.2.0 effectiveTime    20201125

    Base content:   July 2020 International Edition

    New content:    Some additional non-COVID-19 content for the UK                         Any requested new COVID-19 content (as per a microrelease)                         ICD10 and OPCS map updates covering above new content                         Full update of refsets to align with new content

    NB the opportunity and need for further emergency unscheduled microreleases of COVID-19 specific content in addition to the above schedule remains a possibility, although they would always coincide with an already scheduled 4-weekly release of the UK SNOMED CT Drug Extension. Should this happen, the only possible dates for additional microreleases are therefore 15 July, 9 September, 4 November, and 30 December, but currently there are no plans for any such microreleases.

    The subsequent timetable of scheduled releases into 2021 and beyond is not yet finalised – a further consultation on this will occur later in Autumn 2020. Our current preferred option is to continue indefinitely with scheduled releases occurring every 8 weeks, with ad hoc microreleases also able to occur at the 4-weekly mid-point in between those 8-weekly scheduled releases, but with all releases always coinciding with a 4-weekly release of the UK drug extension.

    Planned changes to the SNOMED CT UK Edition release subfolder structure

    Subscribers were previously advised that all future PRODUCTION releases of the Drug and Clinical extension content would transition from April 2020 to the BETA release bundling previously provided as technology previews (Drug and Clinical extension content).

    For a more detailed explanation of the motivations for the BETA bundling, see the webinar recording at https://hscic.kahootz.com/connect.ti/t_c_home/view?objectid=54390437. Detailed information is also provided in the UK Clinical Edition SNOMED CT Technical overview document, section 2.4.1 and 2.4.2.

    To reduce burden during the pandemic, this transition was deferred. Suppliers remain recommended to transition to consuming the BETA rather than PRODUCTION bundlings, in accordance with the following revised schedule:

    Throughout the remainder of 2020, PRODUCTION releases will remain as before but with the same content always co-published on TRUD in BETA format, as Test Releases. Clinical Edition and Drug Extension 29.3.0, RF2, BETA: Full, Snapshot & Delta

    From the first scheduled release in 2021 (27 January), all PRODUCTION releases of UK Clinical and Drug will adopt the BETA encoding. All releases will then continue to be available in parallel in the older LEGACY encoding until the end of March 2021, after which the LEGACY encoding will be permanently withdrawn.

    Reference sets (Refsets)

    Two new UK mapping sRefsets are added to the 17 June 2020 release:

    1323081000000108       Coronavirus disease 19 caused by severe acute respiratory syndrome coronavirus 2 test result communication to general practice concept simple map reference set (foundation metadata concept)

    1323091000000105       Coronavirus disease 19 caused by severe acute respiratory syndrome coronavirus 2 test result communication to general practice description simple map reference set (foundation metadata concept)

    These hold the equivalences between COVID-19 Laboratory Result “short codes” (e.g. SARS-COV-2-ORGY) and their corresponding SNOMED conceptIds and descriptionIds.

    Cross Mapping

    The SNOMED CT to OPCS-4.8, OPCS-4.9 and ICD-10 5th Edition five character maps are included in this 17 June 2020 bi-annual release; there are no changes in this release to either map.

  • Guidance for naming, coding and processing SARS-COV-2 Pathology Tests

    NHS Digital have recently updated the guidance for the national naming, coding and processing of SARS-COV-2 Pathology tests which now contains additional information for Labs and LIMS on naming requestable and reportable items related  to SARS-COV-2 Testing.

    Changes in v2.5.4:

    • Working with the RCPath and the PSGB we have created a detailed set of requestable and reportable items to help laboratories and LIMS suppliers define COVID19 related data items. These include:
      • Requestable Items for Virus detection (including Antigen) and Antibody detection
      • Reportable Items for each detection technique
      • Permissible values for each result
    • Updated guidance on mapping from lab results to SNOMED CT via a set of ‘standardised descriptions’ used to flow the data in the PMIP NHS003 Message
    • Updates to SNOMED CT findings to allow filing of results into Primary Care EPR systems
    • Updates to the structure of the machine readable mapping table now included in the SNOMED CT UK Clinical Extension as a pair of simple map refsets

    This document describes the mapping table changes in the latest version of the guidance

  • National Pathology and Diagnostics May 2020 Newsletter

    Information Sharing Events: our forward view Roadmap

    Dear all,

    At the recent information sharing events in Leeds and London, we shared with you a proposed Pathology Standards Implementation Roadmap for your feedback to enable us to identify any gaps and inform prioritisation.

    The following 3 artefacts were discussed during the sessions and are now available to view on our Pathology and Diagnostics Kahootz site:

    As discussed during the events, the proposed implementation roadmap is split across 5 separate workstreams.

    A summary of the feedback received on each workstream during both of the events can be found here on our Kahootz site

    If you have any additional feedback on the implementation Principles and Roadmap, please contact us via our team mailbox: pathologyanddiagnostics@nhs.net

     

    UTL v0.4 release

    At the recent Information Sharing Sessions in London, we consulted you on two aspects of the UTL Beta Release.

    • Release Schedule - you can find our proposed release schedule within the composite slide set from the events here
    • Human/Beta Readable Release Format - you expressed an interest in receiving a non-HTML version

    Based on your feedback, we produced a text only version of the UTL Beta content, which is provided in `tab delimited format`. 

    We are also proposing a schema specification of the Beta Release Format. This is outlined in the `UTL_Beta_Release_Format_Schema_Guide.pdf` file that is included in the UTL package.

    UTL0.4.0_20200316 was a minor interim release with a modest increase in new content of over 130 rows including the following:

    • Coagulation factors
    • Acylcarnitines by blood spot
    • CD counts,
    • Calculi (stones)
    • Complement
    • Haemoglobin variants.

    The UTL v0.4 package, draft editorial principles and product description were published on our UTL Kahootz page on 18th March and can be accessed here

    In light of the current COVID-19 Pandemic we have decided not to release the machine-readable RF2 version of UTL v0.4.0 on TRUD to allow for focus on other priorities.

    Future release plans will be shared with our user community as soon as they are available.

     

    COVID-19 and Pathology

    As a result of discussions with a number of organisations, a number of standard codes and descriptions for tests and test results related to COVID-19 have now been developed. These were circulated to Public Health England; NHSX; middleware, OrderComms, Laboratory and GP system suppliers. Following feedback and final agreement these were published as part of the UK SNOMED CT Clinical Edition on 22 April 2020

    Guidance for end users on these is incorporated in a document produced in collaboration with the PRSB which can be found here on the COVID-19 Information Standards Kahootz site; please note this includes clinical care related terms as well.

    In addition, NHS Digital have produced guidance for the national naming, coding and processing of SARS-COV-2 Pathology tests. 

    Please note that the current version of this guidance (v1.1.7) covers the population of PMIP NHS003 messages and the mapping of the message payload to SNOMED CT for filing into General Practice EPR systems.

    The next version on the guidance (v2.0) will be published shortly and will contain additional information for Labs and LIMS on naming requestable and reportable items related to SARS-COV-2 Testing.

     

    Pathology FAQ’S

    We have recently published a new frequently asked questions database on the Pathology and Diagnostics Kahootz site based on queries raised during  our recent stakeholder engagement events and monthly "introduction to SNOMED CT in Pathology" webinars. The content of the FAQs database can now be searched and sorted, and will be reviewed and updated on a regular basis

     

    Education and training materials

    During the last PINUG meeting we presented an overview of our Pathology Information Standards education and training materials. There is already a wealth of useful information on our Kahootz site including guidance documents, case studies, technical resources and animations.

    We are keen to develop further bespoke training materials to meet our stakeholder requirements and with this in mind would like to invite you to answer the following electronic survey  which should take no longer than 5 minutes to complete. Your input will ensure that the materials developed are what you want and in formats that you find easiest to digest.

     

    Pathology Informatics National User Group (PINUG)

    The last PINUG meeting was held on the 12th May and discussions focused on the feedback from our recent Information sharing events in Leeds and London.

    Requesting and Test Sets (Panels)

    At the Pathology and Diagnostics information sharing events in Feb/March this year we made a request to attendees for them to share information with us on:

    1. Test codes, names and descriptions (essentially all descriptive data available) on the pathology tests being ordered in their area
    2. Equivalent data for named “Test Sets” (aka Panels/Profiles/Batteries…), plus the relationships between the Sets and the component single tests
    3. Volumetric data (tests requested over a defined period), to help us identify and prioritise the most heavily used tests and Test Sets

    We are grateful to the first two organisations that have responded to this request.

     

    Harrogate and District NHS foundation Trust

    NHS Harrogate were the first to respond with a data extract from their LIMS. Working with the Trust we have been through several iterations of the extract, understanding and refining the data. This has provided a valuable initial view of real-world local lab data, and also enabled us to clarify and document the data set we need to capture from other labs to form a broader picture of requesting codes and practice across the country.

     

    LIMS Supplier Data

    A LIMS software supplier in the UK have made available to us a data extract covering a number of active labs in the UK. At the supplier’s request the names and identities of the labs involved have been obscured in the data set. With this caveat in place they have agreed to make the data available to the project, and to the wider stakeholder group, in support of the overall aims of the project.

    The response to the Covid-19 epidemic has made further engagement with Labs impractical over the last 2 months. We hope that as the situation begins to stabilise we will be able to re-open discussions and gather more data in support of our standardisation work.

    The next PINUG meeting will be on the 14th July 2020: If you would like to attend please make the request through the Pathology and Diagnostics Mailbox:

    pathologyanddiagnostics@nhs.net.

  • SNOMED CT UK Clinical Edition, RF2 29.1.0 Release Published

     

    Published: April 2020

    Dear colleague,

    The SNOMED CT UK Clinical Edition, RF2 for April 22nd 2020 is now available for download from the following links:

    The SNOMED CT UK Drug extension is not released as part of the SNOMED CT biannual release. SNOMED CT UK Drug Extension data is published on a four-weekly cycle within the "UK Drug Extension, RF2" sub pack on TRUD. Please review the associated documentation for more details.

    Release documentation is now only accessible on Delen, at https://hscic.kahootz.com/connect.ti/t_c_home/view?objectId=16607376.

    Further incremental “microreleases” of the UK SNOMED CT Clinical Extension will occur with new COVID-19 related content for the NHS. These will coincide with at least the next two scheduled releases of the UK SNOMED CT Drug Extension (20 May and 17 June).

    A full release comprised of substantially all new content deferred from the original 1 April release candidate remains to be scheduled, having previously been tentatively planned for October 2020. Similarly, future releases are required to update the UK SNOMED to the prevailing current SNOMED International release.

    Combined with the ongoing effects and requirements of the pandemic, this SNOMED release backlog introduces significant uncertainty and opportunity, and our future release schedule therefore remains ultimately “fluid”.

    In the near term we are primarily responding to urgent clinical need, but in June/July 2020 will consult our NHS and IT supplier stakeholders in respect of preferred options in respect of the range of possible future release schedules and their scope.

    Subscribers were previously advised that, from April 2020 all future PRODUCTION releases of the Drug and Clinical extension content would transition to the BETA release bundling previously provided as technology previews. This transition remains deferred: the PRODUCTION release will remain as before; BETA format releases will continue to be published alongside.

    For a more detailed explanation of the issues behind the BETA bundling, see the webinar recording at https://hscic.kahootz.com/connect.ti/t_c_home/view?objectid=54390437

    Reference sets (Refsets)

    There are no new UK refsets for the April 22nd 2020 release.

    Cross Mapping 

    The SNOMED CT to OPCS-4.8, OPCS-4.9 and ICD-10 5th Edition five-character maps are included in this April 22nd 2020 bi-annual release, including minor changes to the ICD10 maps for certain COVID-19 SNOMED codes.
