An update on World Health Organization (WHO) Executive Board and World Health Assembly (WHA) business:

The 144th Session (EB144) of the World Health Organization Executive Board took place in Geneva between 24 January — 1 February 2019.

Executive Board 144th Session website

“The Executive Board is composed of 34 individuals technically qualified in the field of health, each one designated by a Member State elected to do so by the World Health Assembly. Member States are elected for three-year terms.

“The Board meets at least twice a year; the main meeting is normally in January, with a second shorter meeting in May, immediately after the Health Assembly. The main functions of the Executive Board are to give effect to the decisions and policies of the Health Assembly, to advise it and generally to facilitate its work.”

These January Executive Board meetings generate a considerable number of documents. Documentation is available from this page EB144 Meeting Documents.

Key document for Recommendation for Adoption of ICD-11 at WHA72:

World Health Organization, EXECUTIVE BOARD 144th Session

Provisional agenda item 5.9

EB144/22 12 December 2018

Eleventh revision of the International Classification of Diseases

Report by the Director-General

On p10 (Item 53), the Executive Board was invited to consider a draft resolution.

Below is the document containing the text of the draft resolution with proposed amendments from Member States inserted in bold text:

World Health Organization, EXECUTIVE BOARD 144th Session

Agenda item 5.9

EB144/CONF./9 31 January 2019

Eleventh revision of the International Classification of Diseases

Draft resolution proposed by the Secretariat with amendments from Member States

World Health Assembly

The 72nd World Health Assembly takes place this month, in Geneva, from 20 — 28 May 2019.

“The World Health Assembly is the decision-making body of WHO. It is attended by delegations from all WHO Member States and focuses on a specific health agenda prepared by the Executive Board. The main functions of the World Health Assembly are to determine the policies of the Organization, appoint the Director-General, supervise financial policies, and review and approve the proposed programme budget. The Health Assembly is held annually in Geneva, Switzerland.”

ICD-11 endorsement

Next month, the World Health Organization (WHO) intends to present a stable version of ICD-11 to the 72nd World Health Assembly for member state endorsement.

The WHO Executive Board will submit a Resolution for adoption of what it describes as a “preparation for implementation” version of the ICD-11 Mortality and Morbidity Statistics (ICD-11 MMS).

#WHA72 Geneva May 22–28, 2019 

Website: SEVENTY-SECOND WORLD HEALTH ASSEMBLY

Two key documents:

Provisional Agenda Item 12.7 (A72/29): ICD-11 Report by the Director-General

(A72/29 Add.1): Draft Resolution for adoption of ICD-11

If adopted, endorsement would not come into effect until 1 January 2022.

After that date, member states can begin reporting data using the ICD-11 code sets when their countries have prepared their health systems for transition and implemented the new edition.

There is no mandatory date by which member states must migrate to the new edition and for a period of time, data will be collected and aggregated using both ICD-10 and ICD-11. It’s anticipated that even the earliest implementers will take several years to prepare their countries for transition.

Update and revision

Once endorsed, ICD-11 will be subject to an annual update and revision process, as ICD-10 has been.

Minor changes to content can be considered for incorporation on an annual basis. Major changes would be considered for incorporation on a 5 yearly update cycle.

Responsibility for reviewing and processing proposals now lies with the Medical Scientific Advisory Committee (MSAC) and the Classifications and Statistics Advisory Committee (CSAC), which takes over from the ICD-10 Update and Revision Committee (URC). These committees are working through a backlog of proposals.

The ICD-11 Proposal Mechanism platform will remain online and open to stakeholders for new comments and new submissions for changes, additions and improvements. Submissions for changes will also be received from member states via the WHO-FIC Network.

[See ICD-11 Reference Guide: 3.8 Annex: ICD-11 Updating and Maintenance for information on the ICD-11 update and revision cycle and protocol for submission of new proposals.]

Recently processed proposals

Between February and April, this year, a number of proposals were processed.

These include proposals for Postviral fatigue syndrome, Benign myalgic encephalomyelitis and Chronic fatigue syndrome; proposals for Fatigue (was Malaise and fatigue in ICD-10); and proposals for Bodily distress disorder.

Proposals submitted before March 30, 2017 were supposed to have been reviewed before the end of 2017 for consideration for potential inclusion in the initial release of the ICD-11 MMS — but many of these weren’t processed, despite having met the submission deadline.

Proposals relating to Postviral fatigue syndrome and its inclusion terms were in any case put on hold while an evidence review was undertaken. This review was not completed until late 2018.

This batch of recently processed proposals includes proposals submitted by Suzy Chapman (since 2014); by Suzy Chapman and Mary Dimmock (March 2017); and by Lily Chu MD on behalf of the IACFS/ME (March 2017).

The proposal submitted by the WHO’s Dr Tarun Dua, in November 2017, to delete Postviral fatigue syndrome from the Diseases of the nervous system chapter and reclassify ME/CFS [sic] in the Symptoms, signs chapter as a child under Symptoms, signs or clinical findings of the musculoskeletal system was processed in November 2018.

The WHO rightly rejected Dr Dua’s proposal, in a decision supported by the MSAC and CSAC Committees.

Status of processed proposals at April 15, 2019:

In order to access the ICD-11 Proposal Mechanism registration with the platform is required and the platform is clunky to navigate.

For ease of access, I have created a table which sets out the outcome of these processed proposals for Postviral fatigue syndrome, Benign myalgic encephalomyelitis and Chronic fatigue syndrome; Fatigue; and Bodily distress disorder.

(If you already have v1 or v2 of this document, please replace with v3 below, as this document has been updated to include the approval of an exclusion for PVFS under Fatigue.)

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

April 13, 2019 by

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:

 

Screenshot: SNOMED CT Netherlands Edition as it now stands:

 

 

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:

https://browser.ihtsdotools.org/?

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.

Select:

“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.

Update on the status of the classification of PVFS, ME and CFS for ICD-11: Part Three: WHO rejects Dr Dua’s proposal

Update on the status of the classification of PVFS, ME and CFS for ICD-11: Part Two

 

Part Three (and it’s good news, for once)

As reported in Parts One and Two, three proposals for the ICD-10 G93.3 legacy categories, Postviral fatigue syndrome; Benign myalgic encephalomyelitis; and Chronic fatigue syndrome have sat unprocessed in the ICD-11 Proposal Mechanism for over a year:

the proposal by Dimmock & Chapman (submitted March 26, 2017);

the proposal by Dr Lily Chu on behalf of the IACFS/ME (submitted March 31, 2017);

the proposal by Dr Tarun Dua (submitted November 06, 2017).

If you are not registered for access to the ICD-11 Proposal platform, click to download the proposal submitted by Dimmock & Chapman in PDF format.

 

Dr Tarun Dua’s proposal to kick the G93.3 legacy categories out of the Neurology chapter

Dr Tarun Dua is a medical officer working on the Program for Neurological Diseases and Neuroscience, Management of Mental and Brain Disorders, WHO Department of Mental Health and Substance Abuse. This WHO department has responsibility for both mental disorders and neurological diseases and disorders. Its Director is Dr Shekhar Saxena.

Dr Dua had acted as lead WHO Secretariat and Managing Editor for ICD Revision’s Topic Advisory Group (TAG) for Neurology, which was chaired by Prof Raad Shakir.

When Dr Dua submitted a proposal, last year, recommending that “Myalgic encephalitis/Chronic Fatigue Syndrome (ME/CFS)” [sic] should be removed from the Diseases of the nervous system chapter and reclassified in the Symptoms, signs chapter as a child under Symptoms, signs or clinical findings of the musculoskeletal system, it was initially unstated whose position this controversial recommendation represented.

Read Dr Dua’s proposal in PDF format from Page 5 of this November 2017 commentary.

TAG Neurology had ceased operations in October 2016, leaving proposals for the G93.3 legacy categories hanging and the terms still unaccounted for in the public version of the ICD-11 Beta draft. The terms were eventually restored to the draft in March 2017.

Since early 2017, we had been advised several times by senior WHO officers that decisions regarding these categories were “on hold” while an in-house evidence review was being undertaken.

Moreover, WHO senior classification expert, Dr Robert Jakob, had assured me (via email in March 2017) that WHO had no intention of dumping these categories in the Symptoms, signs chapter — yet here was Dr Dua calling for precisely that.

The key question being: Did this recommendation represent the outcome of a now concluded evidence review or did it represented only the position of Dr Dua?

Dr Dua eventually stated that “…the proposal [had] been submitted on behalf of Topic Advisory Group (TAG) on Diseases of the Nervous System, and reiterates the TAG’s earlier conclusions.” But neither Dr Dua nor her line manager, Dr Saxena, were willing to provide us with responses to other queries raised in relation to this proposal, including, crucially: How does this proposal relate to the in-house evidence review?

We were subsequently advised by WHO’s Dr John Grove (Director, Department of Information, Evidence and Research) that the systematic evidence review would determine if the terms needed to be moved to any other specific chapter of ICD-11 and that the outcomes would be provided for review by the Medical Scientific Advisory Committee (MSAC).

A formal response by Dimmock & Chapman to Dr Dua’s proposal can be read in PDF format here Response by Dimmock & Chapman to Dr Tarun Dua proposal of November 6, 2017.

 

WHO rejects Dr Dua’s proposal 

On November 19, the proposal was marked as Rejected by ICD-11 Proposal Mechanism admins:

Screenshot: Accessed November 20, 2018:

https://icd.who.int/dev11/proposals/f/en#/http://id.who.int/icd/entity/569175314

This decision to reject Dr Dua’s recommendation that the terms should be relocated under the Symptoms, signs chapter is accompanied by a brief rationale from ICD-11 Proposal Platform admins “Team3 WHO”:

Screenshot: Accessed November 22, 2018:

 

Importantly, the decision to retain the terms in the Disorders of the nervous system chapter is supported by the WHO MSAC and CSAC committees.

(See Reference 10 for WHO/ICD-11’s guiding principles for consideration of legacy terms and potential chapter relocations — guidance with which Dr Dua is familiar and has cited, herself, when drafting other proposals, but which she evidently chose to disregard in the case of the G93.3 legacy categories.)

 

This means that these ICD-10 legacy terms continue to stand as per the “Implementation” version of the ICD-11 MMS that was published in June 2018:

https://icd.who.int/browse11/l-m/en#/http%3a%2f%2fid.who.int%2ficd%2fentity%2f569175314

 

But we are not done yet…

It’s not known when the remaining proposals submitted by myself and jointly with Mary Dimmock will be processed.

There remains a backlog of over 1000 unprocessed proposals, a number of which had met the March 30, 2017 proposal deadline and were expected to have been processed last year, in time for consideration for inclusion in the June 2018 “Implementation” release.

According to summary reports of the WHO-FIC Network Council’s April 26 and September 26, 2018 teleconferences:

  • Between June 2018 and the 2019 [World Health Assembly] resolution, WHO will work to improve user guidance around the classification and any final sorting of the extension codes, but there is not an intention to “reopen the package” of ICD-11 or to make major changes
  • The codes will not change after June 2018, and the URIs [Unique Reference Identifiers] will remain the constant, immoveable identifiers for each concept that underpin the classification
  • An update cycle was agreed by JTF [Joint Task Force] last week, including ongoing update of foundation entities (e.g. index terms, synonyms, extension codes, etc.) with
    • annual updates for entities below the shoreline,
    • a 5-year cycle for update of entities above the shoreline, and
    • a 10-year cycles for updates to the rules.

and from the September 26, 2018 teleconference:

  • WHO has updated the proposal platform to allow voting by CSAC* members and to align the process with the historical practices of the URC [ICD-10 Update and Revision Committee].
  • 90 proposals have been identified from the platform for consideration by the CSAC this year, though not all of them can be reviewed in detail face-to-face during the WHO-FIC Network Annual Meeting 2018. A call may be held in advance to discuss some specific priorities.
  • Given the huge volume of proposals, the meeting will go through the new procedures for the CSAC, review the voting process and tools, overview the proposal platform and how to use it, and determine timelines and workload for after the meeting.
  • CSAC governance will also be presented together with the content of ICD-11 prior to submission of the report on ICD-11 to the WHO Governing Bodies for review by the WHO Executive Board [in January 2019]

*The Classifications and Statistics Advisory Committee (CSAC) takes over the role of the ICD-10 Update and Revision Committee (URC). The last update for ICD-10 will be 2019.

 

The ICD-11 MMS is expected to be frozen again in January 2019 in preparation for submission of the report to the Executive Board (EB):

 

Beyond World Health Assembly adoption, ICD-11 will be subject to an update and maintenance cycle:

(See Reference Guide Annex 3.7.1 – 3.7.6 for detailed information on ICD-11 Updating Cycles and Proposal Workflows.)

I’ve been unable to confirm whether the first update released after the June 2018 “Implementation” version would be a January 2019 release, or whether the June 2018 version is intended to remain more or less stable for a further year, until January 2020.

If WHO were to accept any of the proposals contained within my individual submissions and my joint submissions with Mary Dimmock, for example, approving our recommendations for deprecating the prefix “Benign”; deprecating Postviral fatigue syndrome as lead Concept Title; assigning separate Concept Title codes to Myalgic encephalomyelitis and to Chronic fatigue syndrome; or approving Exclusions under Bodily distress disorder (BDD), any approved recommendations would appear initially in the orange ICD-11 Maintenance Platform pending their eventual incorporation into an “Implementation” release.

I will keep you apprised of any significant developments.

Update to addition of Disorder of nervous system parent for Chronic fatigue syndrome and terms under Synonyms in SNOMED CT

October 5, 2018 by

Post #345 Shortlink: https://wp.me/pKrrB-4uk

In Post #342 (August 1, 2018), I confirmed that the addition of parent: Disorder of nervous system to Chronic fatigue syndrome was implemented for the July 31, 2018 release of the SNOMED CT International Edition.

The SNOMED CT Concept term for Chronic fatigue syndrome is SCTID 52702003 Chronic fatigue syndrome (disorder). Benign myalgic encephalomyelitis; and Myalgic encephalomyelitis are included in a list of terms under Synonyms.

SCTID: 52702003 Chronic fatigue syndrome (disorder) and the terms listed under Synonyms are now located under supertype SCTID: 118940003 Disorder of nervous system (disorder). This change to the International Edition is being incorporated into the national editions, as they release their next updates. These are released on a staggered schedule.

The rationale for requesting this additional supertype for Chronic fatigue syndrome and the terms listed under Synonyms is set out in this August 2018 document:

PDF: Statement on SNOMED CT and Chronic fatigue syndrome

Note that prior to July 2015, Postviral fatigue syndrome had been listed under Children to SCTID: 52702003 Chronic fatigue syndrome.

But for the July 2015 release, Postviral fatigue syndrome was removed from under SCTID: 52702003 Chronic fatigue syndrome and relocated under supertype: Post-viral disorder under: Post-infectious disorder and assigned the Concept code: SCTID: 51771007.

(A change that had not been requested by the Countess of Mar during her 2014-2015 engagement with SNOMED CT terminology managers for the removal of the Mental disorder parent. Provision of the rationale for relocating Postviral fatigue syndrome was not pursued by Forward-ME.)

Incorporation of addition of supertype Disorder of nervous system into national editions

SNOMED CT U.S. Edition incorporated the change for its September 01, 2018 release:

 

SNOMED CT Belgium Edition incorporated the change for its September 15, 2018 release:

 

SNOMED CT Danish Edition incorporated the change for its September 30, 2018 release:

 

SNOMED CT Netherlands Edition incorporated the change for its September 30, 2018 release:

Note on inclusion of “neurasthenie” in the Netherlands Edition: SNOMED CT International Edition and national editions used to include a Concept term SCTID: 192439005 Neurasthenia. This Concept was retired (Inactivated) a number of years ago. However, the Netherlands Edition retained the term “neurasthenie” under the list of Synonym terms. “Neurasthenie” is designated as an “Acceptable” term in the Netherlands Dutch language reference set (open “Details” tab to view Netherlands reference sets).

Details tab:

A Netherlands advocate has contacted Pim Volkert (Terminology Co-ordinator, Nictiz, and lead for the Netherlands SNOMED CT National Release Centre) with a request and rationales for consideration of the removal of the “neurasthenie” term, for consistency with the SNOMED CT International Edition and with the WHO’s ICD-10, which has an exclusion for G93.3 under F48.0 Neurasthenia. This request has been considered and accepted. I am advised that removal of the “neurasthenie” term is anticipated to be implemented for the March 2019 release of the Netherlands Edition.

 

SNOMED CT UK Edition incorporated the change for its October 01, 2018 release:

(Public browser hosted by NHS Digital. Browser can also be accessed from the landing page of the SNOMED CT International browser platform.)

Note: the UK Edition has three severity specifier options listed under “Children” that are specific to the UK Edition.

These are assigned the discrete codes: SCTID: 377181000000104 Mild chronic fatigue syndrome; SCTID: 377171000000101 Moderate chronic fatigue syndrome; and SCTID: 377161000000108 Severe chronic fatigue syndrome.

It has yet to be established from NHS Digital in which year these severity specifier options were added to the UK Edition, to what extent they are used, and by what means clinicians would determine which of the severities to apply.

The UK Edition includes the terms Myalgic encephalitis and Myalgic encephalopathy.
