Update on ICD-11 Beta drafting platform listing for “Bodily distress disorder”

This post is an update to Post #291, January 29, 2014, titled:
Between a Rock and a Hard Place: ICD-11 Beta draft: Definition added for “Bodily distress disorder”
Caveat: The ICD-11 Beta drafting platform is not a static document: it is a work in progress, subject to daily edits and revisions, to field test evaluation and to approval by Topic Advisory Group Managing Editors, the ICD Revision Steering Group and WHO classification experts.
Since the release of the initial iCAT drafting platform, in 2010, the Somatoform disorders section of Chapter 05 has undergone numerous iterations.
In Post #291, I reported on the status of the Beta drafting platform at January 29, when it had stood like this:

There has been a further recent change to this section of the drafting platform and the draft currently stands like this:
Source: ICD-11 Beta drafting platform, Chapter 05, at February 24, 2014
In the Foundation Component, the severity specifier, Severe bodily distress disorder, has now been removed.
ICD-10’s Somatization disorder has been reinserted as a child category under Bodily distress disorder.
The term Bodily distress disorder is cross referenced to ICD-10 F45 Somatoform disorders.
Somatoform disorders is listed under Synonyms to Bodily distress disorder.
The Definition for Bodily distress disorder remains the same as previously reported:
“Bodily distress disorder is characterized by high levels of preoccupation regarding bodily symptoms, unusually frequent or persistent medical help-seeking, and avoidance of normal activities for fear of damaging the body. These features are sufficiently persistent and distressing to lead to impairment in personal, family, social, educational, occupational or other important areas of functioning. The most common symptoms include pain (including musculoskeletal and chest pains, backache, headaches), fatigue, gastrointestinal symptoms, and respiratory symptoms, although patients may be preoccupied with any bodily symptoms. Bodily distress disorder most commonly involves multiple bodily symptoms, though some cases involve a single very bothersome symptom (usually pain or fatigue).”
Note: these psychobehavioural responses that characterize the disorder are based on text in the 2012 Creed and Gureje paper on emerging proposals for Bodily distress disorder [1].
That paper also says that in doing away with the “unreliable assumption of its causality” the diagnosis of BDD does not exclude the presence of a co-occurring physical health condition – which describes a disorder framework into which DSM-5′s “Somatic Symptom Disorder” (SSD) would be capable of integration, allowing harmonization between ICD-11 and DSM-5.
The Exclusions listed under Bodily distress disorder are legacy terms imported from ICD-10’s Somatoform disorders section. Hypochondriasis has also been inserted as an Exclusion to Bodily distress disorder.
If you open the description display pane for child category, Somatization disorder:
you’ll see that the Definition that has been reinserted is legacy text imported from ICD-10’s F45.0 Somatization disorder.
The Definition includes the text: “Short-lived (less than two years) and less striking symptom patterns should be classified under undifferentiated somatoform disorder (F45.1).”
Note: there is no Undifferentiated somatoform disorder listed in the ICD-11 Beta draft. I cannot confirm whether ICD-11 Revision also intends to reinsert Undifferentiated somatoform disorder to the ICD-11 Beta draft, or whether this represents an oversight on the part of the Beta draft Managing editors to edit the text that has been imported from ICD-10 to accord with ICD-11 proposals.
If you go to the Foundation Component view:
http://apps.who.int/classifications/icd11/browse/l-m/en#/http://id.who.int/icd/entity/767044268
and hover over the blue, red, yellow, green button at the top right of the chapter listings, the hover reads
“show/hide availability in main linearizations”.
Click on the button and coloured tags will display at the beginning of each category term which indicate the availability of that term within the various linearizations.
For example, hovering over the colour tags for Bodily distress disorder indicates that this Foundation Component term is available in “In Mortality and Morbidity, Primary Care High Resource, Primary Care Low Resource” linearizations.
Hovering over the recently re-inserted Somatization disorder indicates that this Foundation Component term is available “In Mortality and Morbidity, Primary Care High Resource, Primary Care Low Resource” linearizations. (On February 18, it was displaying as available only in Foundation, Primary Care High Resource and Primary Care Low Resource.)
Neurasthenia
A further change – Neurasthenia has also been reinserted into the Beta draft!
Neurasthenia had previously been proposed to be eliminated for ICD-11 or subsumed under Bodily distress disorder along with seven Somatoform disorder categories:
Somatization disorder;
Undifferentiated somatoform disorder;
Somatoform autonomic dysfunction;
Persistent somatoform pain disorder;
Chronic pain disorder with somatic and psychological factors [not in ICD-10 but had been proposed for ICD-11];
Other somatoform disorders;
Somatoform disorder, unspecified
Neurasthenia has also been proposed to be eliminated from the Primary Care version (ICD-11-PHC), according to the 2012 proposals of the Primary Care Consultation Group, but now its back in the draft and listed for Foundation Component, Primary Care High Resource and Primary Care Low Resource linearizations (but not Mortality and Morbidity).
It is currently listed thus:
http://apps.who.int/classifications/icd11/browse/f/en#/http://id.who.int/icd/entity/1784516726
The Long Content Model Definition that displays in the disorder description pane is the legacy F48.0 text unmodified from ICD-10.
Fatigue syndrome* is specified as the Inclusion term, as per ICD-10. [If you hover over the asterisk in the draft it displays the hover: “This term is an inclusion term in the linearizations”.]
ICD-10 G93.3 category, postviral fatigue syndrome, remains listed as an Exclusion to Neurasthenia, as it does in ICD-10.
So what are the implications?
Without clarifications from ICD Revision it cannot be determined from what displays in the public version of the Beta draft what the current intentions are, or how these revised proposals would accommodate the restoration of Somatization disorder and Neurasthenia within the BDD framework (at least as the BDD framework stood in the 2012 Creed and Gureje emerging proposals paper).
All that can safely be said in relation to this section of the draft is:
• that the section parent category remains Bodily distress disorder;
• that a child category, Somatization disorder, which was previously one of a handful of SDs proposed to be replaced by a single new BDD category, has now been reinserted for the Foundation Component, Mortality and Morbidity, Primary Care High Resource and Primary Care Low Resource linearizations, with its Definition text unmodified from ICD-10.
• that currently, the Definition text for Somatization disorder is unmodified from ICD-10 and includes an unexplained reference to F45.1 Undifferentiated somatoform disorder*.
• that Severe bodily distress disorder is no longer listed in any linearization, at least in the public version of the Beta drafting platform.
• that Neurasthenia, which was previously proposed to be eliminated for both the core and primary care versions, is now back in the Beta draft for Foundation Component, Primary Care High Resource and Primary Care Low Resource linearizations, with its Definition text unmodified from ICD-10.
But I have no clarification of intention or any information on what definition, disorder descriptions and criteria set will be going forward to ICD-11 field tests, and it could all change again, next week…
*In DSM-5, Somatic symptom disorder is cross-walked to ICD-10-CM F45.1 Undifferentiated somatoform disorder.
NCHS/CMS has proposed to insert the term Somatic symptom disorder into ICD-10-CM as an Inclusion to F45.1 Undifferentiated somatoform disorder.
