Update on the removal of “neurasthenie” from SNOMED CT Netherlands Edition

Post #348 Shortlink: https://wp.me/pKrrB-4N6

As reported in Post # 345, the SNOMED CT Concept SCTID: 192439005 Neurasthenia (disorder) and its associated SCTID Concept terms were retired (Inactivated) from SNOMED CT’s International Edition and from national editions some years ago.

However, the Netherlands Edition retained the term neurasthenie under the SCTID: 52702003 chronischevermoeidheidssyndroom (CVS) Synonyms list. The neurasthenie term was exclusive to the Netherlands Edition, was assigned to the SCTID: 52702003 CVS code, and designated as an “Acceptable” Synonym term for CVS in the Netherlands Dutch language reference set.

Request for removal of the neurasthenie term:

In October 2018, a Netherlands advocate approached Pim Volkert (Terminology Co-ordinator, Nictiz, and lead for the Netherlands SNOMED CT National Release Centre) with a request and rationale for consideration of removal of the neurasthenie term, for consistency with SNOMED CT International Edition and with the WHO’s ICD-10, which specifically excludes G93.3 from F48.0 Neurasthenia.

This request and accompanying rationale was considered and promptly accepted for implementation in the March 31, 2019 release of the Netherlands Edition.

This approved content change has now been incorporated into the March 2019 release:

A note about retired SCTID Concept terms and retired Synonyms in SNOMED CT International Edition and national editions:

The technical term for the retirement of a SNOMED CT SCTID Concept or Synonym term is “Inactivation”. In order to display Inactive concepts, go to:


Accept the License Agreement, if displayed.

Select the specific edition required (eg the International Edition or one of the National Editions).

Look under Options on the left of the Search box.


“Status: Active and inactive concepts” from the Options dropdown.

Enter a search term into the Search box.

In the Matches list, Inactive concepts will display on a light pink ground.

Click on a term to display the historical Concept Details panel associated with that specific term (which will also display on a pink ground in the box under Parents in the Concept Details panel).

So although retired or “Inactive” terms can still be searched for within the SNOMED CT terminology browser, they are identified as Inactive by their pink ground.


ICD-11 Revision releases External review and Response: shifts projected WHA adoption to 2018

Post #321 Shortlink: http://wp.me/pKrrB-44N

Update: August 6, 2015

ICD Revision has now published a revised Project Plan and Communication Schedule:

ICD Project Plan 2015 to 2018


As previously posted


And so it goes on…

The revision of ICD-10 and development of ICD-11 kicked off in April 2007. The original projected WHA adoption date was 2011/12 [1].

Then a shift to 2015, then to 2017.

WHO has just kicked the can further down the road to May 2018.

In July 2014, the World Health Organization (WHO) Office of the Assistant Director General, Health Systems and Innovation, posted a call for expressions of interest from suitable contractors to conduct an interim assessment of the 11th Revision for International Classification of Diseases (ICD).

External assessment was prompted by concerns raised by WHO Member States, UN Statistical Commission and other stakeholder organizations about the status of the revision and the utility of the ICD-11 product.

The External review of ICD-11 Revision’s progress has now been completed.

Last week, WHO quietly released a report on the status of the ICD revision process, its management and resources, the feasibility of meeting its goals and timelines, and its fitness for purpose.

The reviewers’ assessment and recommendations can be read here: External report

Read WHO’s initial response to the report’s findings and the actions ICD Revision proposes to take here: WHO Response to External Report

WHO says:

WHO welcomes the constructive messages of the Report of the ICD-11 Revision Review. WHO is initiating the second phase of the revision process, acting immediately on the Review’s recommendations.

A revised workplan will be formulated before the end of June and submitted for approval to the RSG-SEG. During 2015 the WHO secretariat will be strengthened in terms of project management, communication of progress and plans, documentation and transparency of decision-making and classification expertise, as recommended by the reviewers.

As I predicted, a further shift in the development timeline from WHA adoption in May 2017 to May 2018 is proposed, along with other measures.

WHO considers further extension to ICD-11 development timeline

Post #275 Shortlink: http://wp.me/pKrrB-3sc

Information in this report relates to the World Health Organization’s ICD-11, currently under development. It does not apply to the current ICD version (ICD-10) or to the forthcoming US specific “clinical modification” of ICD-10, known as ICD-10-CM.

Timeline slippage

Documents posted recently by the World Health Organization (WHO) indicate that ICD Revision is failing to meet development targets and a further extension to the ICD-11 timeline is under consideration.

ICD serves as the international health information standard for the collection, classification, processing and presentation of disease-related data in national and global health statistics.

The 10th edition (ICD-10) was adopted by the World Health Assembly in 1990.

The development process for the next edition (ICD-11) began in April 2007, with ICD-11 scheduled for dissemination by 2012 and the timelines for the development of ICD-11 and DSM-5 running more or less in parallel [1] [2].

Early on in the revision process, the ICD-11 dissemination date was extended. By 2009, the final draft was scheduled for World Health Assembly (WHA) approval in 2014. In order to be ready for global implementation in 2015, the technical work on ICD-11 would need to be completed by 2012 [3].

The WHA approval date was subsequently shunted from 2014 to 2015 – four years later than originally planned and the current, projected implementation date is 2016+.

“…And just a small detail: who will do all this work?” [4]

ICD-11 is a very ambitious and under-resourced project. Given the scale of the undertaking, the technical complexity, the limited funding and human resources, the feasibility of the project reaching its targets by May 2015 has proved unrealistic.

I have written a number of times on this site that I did not envisage dissemination of ICD-11 by 2016 without some scaling back of the project’s scope – or an announcement, at some point this year, of a further extension to the timeline.

ICD-11 Revision Steering Group considers its options

WHO has recently posted a meeting materials document [5] and a slide presentation [6] which summarize, inter alia, ICD-11’s progress, current development status and timelines for finalization date and approval by WHO Governing Bodies.

ICD Revision is considering extending the timeline by up to a couple of years.

or opened on Dx Revision WatchPDF: SA-2013-12-Add1-Health-WHO

It summarizes the status of the ICD Revision process under section headings:

1. Background: need and mandate
2. General organization structure of the multiple streams of work
3. Progress and current status
4. The remaining steps
5. Further maintenance of ICD after finalization
6. Timelines for the finalization date and approval by WHO Governing Bodies

Extracts from the document setting out the rationale and options for postponement of WHA Approval:


3. Progress and Current Status of ICD Revision:



At this point in time, 1 September 2013, an ICD2013 Beta version has been produced for review purposes and field trials after 6 years of drafting phases.

The current ICD 2013 Beta version has relatively stable classification lists (i.e. linearizations) for Mortality and Morbidity recording. It will be reviewed by the specific Mortality Reference Group and the Morbidity Reference Group to see how well it fits the purpose and proposed transition from ICD‐10.

In addition, the Beta version has planned processes for:

(i) Systematic international scientific peer review
(ii) Submission of additional proposals from public groups and scientists
(iii) Conducting field trials for its applicability and reliability
(iv) Production support in multiple languages (translations) starting with WHO official languages
(v) Preparations for transitions from ICD‐10 to ICD‐11.


6. Timelines

The current ICD Revision Process timeline foresees that the ICD is submitted to the WHA in 2015 May and could then be implemented. Between now and 2015, there remains 20 months to conduct the remaining tasks summarized above as: 1. Reviews, 2. Additional Proposals, 3. Field Trials, 4. Translations, and 5. Transition Preparations.

Given the technical requirements these steps could be expedited in the next 20 months. The experience obtained thus far, however, suggests that this timeframe will be extremely tight for paying due diligence to the work especially in terms of: appropriate consultations with expert groups; communication and dissemination with stakeholders; and sufficient time for field testing in multiple countries and settings, and carrying out the resulting edits.

WHO Secretariat would like to discuss this with all stakeholders and evaluate the possible options:

a. Keep ICD submission to WHA to 2015 as originally planned and implementation / adoption date may be free by any Member State (current position – no change).

b. Postpone submission to WHA to a later year to allow longer time for field trials and other transition preparations.


In conclusion:

(a) WHO Secretariat could produce an ICD 2015 ready including Mortality and Morbidity Linearizations, Reference Guide and Index with the appropriate resolution to go to the World Health Assembly. This timeframe, however, is extremely tight for paying due diligence to the work especially in terms of: appropriate consultations with expert groups; and sufficient time for field testing in multiple countries and settings, and carrying out the resulting edits

(b) If the timeline is advanced to 2016, there will be more time to have ICD 2016 version with more translations and incorporations of some field tests results.

(c) If the timeline is advanced to 2017, ICD 2017 will be ready with most Field Test results incorporated and maintenance scheme tested.


If WHO/ICD-11 Revision Steering Group does elect to postpone submission for WHA approval until May 2017, dissemination of ICD-11 may not be scheduled before 2018.

Once approved and released, adoption of ICD-11 won’t happen overnight. It may take several years before WHO Member States adopt ICD-11. Low resource and developing countries may also take longer to prepare for and transition to the new edition.

Note for US readers: According to Page 3332 of DHSS Office of Secretary Final Rule document (Federal Register / Vol. 74, No. 11 / Friday, January 16, 2009 / Rules and Regulations):

“…We [ICD-9-CM Coordination and Maintenance Committee] discussed waiting to adopt the ICD-11 code set in the August 22, 2008 proposed rule (73 FR 49805)…

“…However, work cannot begin on developing the necessary U.S. clinical modification to the ICD-11 diagnosis codes or the ICD-11 companion procedure codes until ICD-11 is officially released. Development and testing of a clinical modification to ICD-11 to make it usable in the United States will take an estimated additional 5 to 6 years. We estimated that the earliest projected date to begin rulemaking for implementation of a U.S. clinical modification of ICD-11 would be the year 2020.” [7]

This projection, in early 2009, would have been based on the assumption that ICD-11 was anticipated to be finalized and submitted for WHA Approval by 2014 (now potentially shifting to 2017).

An additional two year delay in the finalization of the ICD-11 code sets would likely impact on the development process for a clinical modification of ICD-11 for US specific use, kicking adaptation and implementation of an ICD-11-CM even further down the road.
