Notes on ICD-11 Beta drafting platform and DSM-5 draft by Suzy Chapman for Dx Revision Watch:

These notes may be reposted, if reposted in full, source credited, link provided, and date of publication included.

January 6, 2013

1] The publicly viewable version of the ICD-11 Beta drafting platform can be accessed here:
Foundation view: http://apps.who.int/classifications/icd11/browse/f/en
Linearization view: http://apps.who.int/classifications/icd11/browse/l-m/en

2] The various ICD-11 Revision Topic Advisory Groups are developing the Beta draft on a separate, more complex platform accessible only to ICD-11 Revision.

3] The ICD-11 Beta draft is a work in progress and not scheduled for completion until 2015/16. When viewing the public version of the Beta draft please note the ICD-11 Revision Caveats. Note also that not all proposals may be retained following analysis of the field trials for ICD-11 and ICD-11-PCH, the abridged Primary Care version of ICD-11:
http://apps.who.int/classifications/icd11/browse/Help/Get/caveat/en

4] The Bodily Distress Disorders section of the ICD-11 Beta draft Chapter 5 can be found here:
http://apps.who.int/classifications/icd11/browse/f/en#/http%3a%2f%2fwho.int%2ficd%23F45
http://apps.who.int/classifications/icd11/browse/l-m/en#/http%3a%2f%2fwho.int%2ficd%23F45

According to the public version of the ICD-11 Beta drafting platform, the existing ICD-10 Somatoform Disorders are currently proposed to be replaced with Bodily Distress Disorders, and Psychological and behavioural factors associated with disorders or diseases classified elsewhere, not with Bodily distress syndrome as Dr Garralda has in her slide presentation.

The following proposed ICD-11 categories are listed as child categories under parent, Bodily Distress Disorders, and Psychological and behavioural factors associated with disorders or diseases classified elsewhere:

EC5 Mild bodily distress disorder
EC6 Moderate bodily distress disorder
EC7 Severe bodily distress disorder
EC8 Psychological and behavioural factors associated with disorders or diseases classified elsewhere

There are no Definitions nor any other descriptors populated for the proposed, new ICD categories EC5 thru EC7.

EC8 is a legacy category from ICD-10 and has some populated content imported from ICD-10.

+++
These earlier ICD-11 Beta draft Somatoform Disorders categories appear proposed to be eliminated and replaced with the four new categories EC5 thru EC8, listed above:

Somatization disorder [F45.0 in ICD-10]
Undifferentiated somatoform disorder [F45.1 in ICD-10]
Somatoform autonomic dysfunction [F45.3 in ICD-10]
Persistent somatoform pain disorder [F45.4 in ICD-10]
    > Persistent somatoform pain disorder
    > Chronic pain disorder with somatic and psychological factors [Not in ICD-10]
Other somatoform disorders [F45.8 in ICD-10]
Somatoform disorder, unspecified [F45.9 in ICD-10]

5] The existing ICD-10 Chapter V category Neurasthenia [ICD-10: F48.0] is no longer accounted for in the public version of the ICD-11 Beta draft. I have previously reported that for ICD-11-PHC, the Primary Care version of ICD-11, the proposal is to eliminate the term Neurasthenia.

(I cannot confirm whether the currently omission of Neurasthenia from the Beta draft is due to oversight or because ICD-11 Revision’s intention is that Neurasthenia is also eliminated from the main ICD-11 classification.)

+++
6] I have previously reported that for ICD-11-PHC, the abridged, Primary Care version of ICD-11, the proposal, last year, was for a disorder section called Bodily distress disorders, under which would sit Bodily stress syndrome [sic].

This category is proposed for ICD-11 Primary Care version to include “milder somatic symptom disorders” as well as “DSM-5’s Complex somatic symptom disorder” and would replace “medically unexplained somatic symptoms.”

7] Dr Garralda lists Complex Somatic symptom disorder (DSM-V) on Slide 11 of her presentation.

The manual texts for the next edition of DSM are in the process of being finalized for a projected release date of May 2013. The next edition of DSM will be published under the title DSM-5 not DSM-V . The intention is that once published, updates and revisions to DSM-5 will be styled: DSM-5.1, DSM-5.2 etc.

When the third draft of DSM-5 was released in May 2012, the proposal was to merge Complex Somatic Symptom Disorder with Simple Somatic Symptom Disorder and to call this hybrid category Somatic Symptom Disorder.

This would mean that this new disorder has the same name as the overall disorder section it sits under, which replaces DSM-IV’s Somatoform Disorders.

As any subsequent changes to draft criteria sets following closure of the third stakeholder review are embargoed, I cannot confirm whether the SSD Work Group has decided to rename this category to Somatic symptom Disorder or retain the original term, Complex Somatic Symptom Disorder, the term used by Dr Garralda in her presentation.

8] Turning from ICD-11 Beta draft Chapter 5 Mental and behavioural disorders to Chapter 6 Diseases of the nervous system:

As previously reported, Chronic fatigue syndrome is listed under Diseases of the nervous system in the Foundation View. There is no listing for Chronic fatigue syndrome in the Linearization View nor is the term listed in the PDF for Chapter 6, that is available to those who are registered with ICD-11 Beta draft for access to additional content:

http://apps.who.int/classifications/icd11/browse/f/en#http%3a%2f%2fwho.int%2ficd%23G93.3

Documentation from the ICD-11 iCAT Alpha draft dating from May 2010, implies that the intention for ICD-11 is a change of hierarchy for the existing ICD-10 Title term Postviral fatigue syndrome.

In the ICD-11 Beta draft, Chronic fatigue syndrome (which was listed only within the Index volume of ICD-10 and not listed in Volume 2: The Tabular List) appears to be elevated to ICD Title term status, with potentially up to 12 descriptive parameters yet to be completed and populated in accordance with the ICD-11 “Content Model”.

But the current proposed hierarchical relationship between PVFS and CFS for ICD-11 remains unconfirmed.

See image for documentation from the iCAT Alpha drafting platform, from May 2010:

https://dxrevisionwatch.files.wordpress.com/2010/06/change-history-gj92-cfs.png

There is no discrete ICD Title term displaying for Postviral fatigue syndrome in either the ICD-11 Beta Foundation View or Linearization View.

Neither is there any discrete ICD Title term displaying for Benign myalgic encephalomyelitis in either the Foundation View or Linearization View.

Benign myalgic encephalomyelitis appears at the top of a list of terms under “Synonyms” in the CFS description. [The hover text over the asterisk at the end of “Benign myalgic encephalomyelitis” reads, “This term is an inclusion term in the linearizations.”]

Postviral fatigue syndrome is also listed under “Synonyms” along with a number of other terms imported from other classification systems.

Included in this list under “Synonyms” are “chronic fatigue syndrome nos” and “chronic fatigue, unspecified,” both of which appear to have been sourced from the as yet to be implemented, US specific, ICD-10-CM.

+++
At some recent, unspecified date, a Definition has been inserted for ICD-11 Title term Chronic fatigue syndrome into the previously empty Definition field. An earlier Definition was removed when the Alpha draft was replaced with the Beta draft but can be seen in this screenshot, here, from June 2010:

https://dxrevisionwatch.files.wordpress.com/2010/05/2icatgj92cfsdef.png

The current Definition reads (and be mindful of the ICD-11 Caveats):

“Chronic fatigue syndrome is characterized by extreme chronic fatigue of an indeterminate cause, which is disabling andt [sic] does not improve with rest and that is exacerbated by physical or mental activity.”

There are no Definition fields for Benign myalgic encephalomyelitis or Postviral fatigue syndrome as these terms are listed under “Synonyms” to ICD-11 Title term, Chronic fatigue syndrome.

+++
Since one needs to be mindful of the ICD-11 Caveats and as the Chair of Topic Advisory Group for Neurology has failed to respond to a request for clarification of the intention for these three terms and the proposed ICD relationships between them, I am not prepared to draw any conclusions from what can currently be seen in the Beta drafting platform.

I shall continue to monitor the Beta draft and report on any significant changes.

For definitions of “Synonyms,” “Inclusions,” “Exclusions” and other ICD-11 terminology see the iCAT Glossary:
