Summary of responses from WHO re: Bodily distress disorder, Bodily stress syndrome, Bodily Distress Syndrome

Post #313 Shortlink: http://wp.me/pKrrB-3YR

Summary of responses from Dr Geoffrey Reed, WHO

On July 23, I submitted an analysis and four questions via the ICD-11 Beta drafting platform for the attention of the Managing Editors for Topic Advisory Group (TAG) for Mental Health, the advisory group that is revising ICD-10’s Chapter V.

A copy of my comments has been posted in Dx Revision Watch Post #311: Questions raised on ICD-11 Beta draft re: Bodily distress disorder http://wp.me/pKrrB-3Yh

Comments and suggestions submitted by registered users of the ICD-11 Beta drafting platform are screened and forwarded to the appropriate TAG Managing Editors for review.

I also sent a copy of my comments to Dr Geoffrey Reed. Dr Reed is Senior Project Officer overseeing the revision of the ICD Mental and behavioural disorders chapter.

On July 24, I received a response from Dr Reed, via email.

Dr Reed’s responses do not address all the points I had raised via the Beta platform and in my covering email.

I had also drawn his attention to the absence, since early 2013, of the three G93.3 terms from the public version of the Beta draft and collective concerns for ICD Revision’s failure, to date, to respond to multiple requests to provide an explanation for the continued absence of these terms from the public Beta draft and to clarify ICD Revision’s intentions and proposals for the classification [chapter placement(s), parent code(s), hierarchies, Definitions, Synonyms, Inclusion terms etc.] of these three ICD-10 terms within ICD-11.*

*If the consulting team that secures the ICD Revision interim assessment contract extends their outreach to include analysis of advocate stakeholder views and experience of interacting with the revision process, I shall be happy to discuss key concerns.

I am providing a summary of selected of Dr Reed’s comments and responses.

Dr Reed provided the following information on July 24:

The placement of ME and related conditions within the broader ICD-11 classification is still unresolved.

There has been no proposal and no intention to include ME or other conditions such as fibromyalgia or chronic fatigue syndrome in the classification of mental disorders.

That ME and related conditions be clearly identified as NOT being part of this section of the classification could be made absolutely clear through the use of exclusion terms.

However, Dr Reed will be unable to request that exclusion terms be added to relevant Mental and behavioural disorders categories (e.g., Bodily Distress Disorder) until the conditions that are being excluded exist in the classification. At such time, he would be happy to request exclusion terms.

ICD Revision is currently involved in testing the proposals of the ICD-11 Primary Care Consultation Group* in primary care settings around the world, in part to compare how they work with the proposals of the ICD-11 Expert Working Group on Somatic Distress and Dissociative Disorders**.

Whether the primary care proposal ends up capturing specific groups of patients in primary care who are likely to have underlying medical conditions will certainly be one of the issues for examination and further discussion. Study data would be used as a basis for modifying proposals.

That he considers my analysis is accurate.

That it is not WHO policy to make research protocols for field trial studies that are planned or currently being implemented publicly available for comment.

Details of the study methodology at the time the data are published are expected to be provided, in order that others may examine and critique the methodology, their interpretation of results and their subsequent decisions based on the studies.

Further modifications of the proposals will be based on data evaluation, and justifications made available.

In due course, ICD Revision will make more detailed diagnostic guidelines for all Mental and behavioural disorders available for review and comment before they are finalized, but ICD Revision is not yet ready to do that.

Dr Reed will notify me when that occurs, but anticipates this will be before the end of the year and considers there is plenty of time for review as the approval of ICD-11 is now currently planned for May, 2017.

Dr Reed’s purview does not extend to the section on classification of Diseases of the nervous system or other areas outside the Mental and behavioural disorders chapter, and is therefore unable to provide any information related to how these conditions will be classified in other chapters***.

He is unable to comment about the management of correspondence by other TAG groups**** and signposts to another member of WHO staff [who had been copied into the joint organizations' letter to WHO/ICD Revision, in March].

Footnotes:

* Back in 2012, the ICD-11 Primary Care Consultation Group (the PCCG) were proposing a disorder construct that presented a modified version of the Fink et al (2010) Bodily Distress Syndrome (BDS) construct, which the Primary Care group were proposing to call, at that point, “Bodily stress syndrome (BSS).”

The PCCG hasn’t published a progress report since 2012 and the group’s current proposals are not available for scrutiny. If a modified version of BDS is currently being proposed by the PCCG, it isn’t known what changes have been made to the group’s proposals since the Lam et al (2012) paper was published, a paper which is now in the public domain.

An editorial co-authored by Prof David Goldberg, in June 2013, implied that Prof Goldberg, at least, was advancing that BDS should be progressed to ICD-11 field testing. It is unclear from Dr Reed’s responses to what extent the PCCG’s most recent proposals correspond to the disorder descriptions and criteria for Fink et al’s, already operationalized, BDS, or whether the group has retained the “BSS” disorder name for the purposes of the field tests and a modified construct/criteria set.

+++
** In 2012, the ICD-11 Expert Working Group on Somatic Distress and Dissociative Disorders (the S3DWG) were proposing an alternative and divergent disorder construct that had good concordance with DSM-5’s Somatic symptom disorder, and poor concordance with Fink et al’s BDS, which perversely the S3DWG were proposing to call “Bodily distress disorder (BDD)” – a term already being used outside ICD Revision, interchangeably, with Bodily Distress Syndrome.

It is the S3DWG’s BDD construct that has been entered into the ICD-11 Beta drafting platform.

The Beta draft entry for BDD has recently had characterizations inserted for three BDD severity specifiers: BDD, Mild; BDD, Moderate; BDD, Severe. This post (which was written before I received responses from Dr Reed) sets out these recent additions to the draft in the context of the two divergent sets of proposals: Definitions for three severities of Bodily distress disorder now inserted in ICD-11 Beta draft, July 19, 2014 http://wp.me/pKrrB-3X9

Under the subheading “So why have these three ICD-10 terms disappeared and why is ICD Revision reluctant to respond?” I have suggested a number of potential reasons for the current absence of these three terms from the Beta draft.

**** On March 17, a joint letter signed by Sonya Chowdhury, CEO, Action for M.E., Annette Brooke, MP, Chair, All Party Parliamentary Group on M.E., The Countess of Mar, Chair, Forward M.E. and Dr Charles Shepherd, ME Association, was sent to key Topic Advisory Group for Neurology members and copied to WHO’s Dr Margaret Chan, Dr Geoffrey Reed and Dr Robert Jakob.

The letter had requested, inter alia, clarification for the absence of the three ICD-10 G93.3 terms, Postviral fatigue syndrome, Benign myalgic encephalomyelitis and Chronic fatigue syndrome from the public version of the ICD-11 Beta drafting platform.

Prior to early 2013, in the public version of the Beta draft, Chronic Fatigue Syndrome had been listed in the Beta Foundation Component as an ICD Title entity under the Diseases of the nervous system chapter, with Benign Myalgic encephalomyelitis specified as an Inclusion term to CFS, and Postviral fatigue syndrome listed under Synonyms to Title term, CFS.

To date, none of the recipients of the letter has responded or accepted an invitation to discuss these issues at a meeting of either the All Party Parliamentary Group on M.E. or Forward M.E. The joint letter can be read here:

Bodily distress disorder, severe

Comments on title

Suzy Chapman 2014-Jul-23 – 14:01 UTC

Definitions for three uniquely coded severities for Bodily distress disorder: Mild; Moderate; Severe, have recently been inserted into the Beta draft.

The Definition for Bodily distress disorder (BDD) and its three severity characterizations appears to be based on the BDD disorder descriptions in the 2012 Creed, Gureje paper: Emerging themes in the revision of the classification of somatoform disorders [1].

As conceptualized by the ICD-11 Expert Working Group on Somatic Distress and Dissociative Disorders (S3DWG), BDD is proposed to replace the seven ICD-10 Somatoform disorders categories F45.0 to F45.9, and F48.0 Neurasthenia.

The S3DWG’s BDD eliminates the requirement that symptoms be “medically unexplained” as the central defining feature; focuses on identification of positive psychobehavioural responses (excessive preoccupation with bodily symptoms, unreasonable illness fear, frequent or persistent healthcare utilization, activity avoidance for fear of damaging the body) in response to any (unspecific) persistent, distressing, single or multiple bodily symptom(s), resulting in significant impairment of functioning or frequent seeking of reassurance; makes no assumptions about aetiology, and in “[d]oing away with the unreliable assumption of its causality, the diagnosis of BDD does not exclude the presence of (…) a co-occurring physical health condition.”

The S3DWG’s BDD has no requirement for symptom counts, or for symptom patterns or symptom clusters from body or organ systems, which describes a disorder framework with good concordance with DSM-5 Somatic Symptom Disorder (SSD).

According to the Beta draft, BDD’s three severity specifiers are proposed to be characterized on the basis of the extent to which responses to persistent, distressing bodily symptoms are perceived as excessive and on the degree of impairment, not on the basis of number of bodily symptoms and number of body or organ systems affected.

In comparison, psychobehavioural responses do not form part of Fink et al’s (2010) Bodily Distress Syndrome criteria. BDS’s criteria and two severities are based on symptom patterns from body systems (a BDS Modest, single-organ type and a BDS Severe, Multi-organ type).

In 2012, the Lam et al paper [2], set out emerging proposals for the ICD-11 Primary Care Consultation Group’s (PCCG) recommendations for a “Bodily stress syndrome (BSS).”

The PCCG’s proposals described a disorder construct that had good concordance with Fink et al’s Bodily Distress Syndrome, drawing heavily on Fink et al’s criteria set. Although at that point, the PCCG proposed to incorporate some SSD-like psychobehavioural features within their tentative criteria. The PCCG appeared to be proposing a modified version of the Fink et al (2010) BDS construct.

In an Ivbijaro G, Goldberg D (June 2013) editorial [3], the co-authors advance the position that the forthcoming revision of ICD provides an opportunity to include BDS in a revised classification for primary care. According to this June 2013 editorial, the PCCG’s proposal for a modified BDS disorder construct, which it had earlier proposed to call “Bodily stress syndrome (BSS),” appears to have been revised to using the Fink et al “Bodily distress syndrome (BDS)” term.

The editorial implies that BDS (which subsumes the so-called “functional somatic syndromes,” CFS, ME, IBS, Fibromyalgia, chronic pain disorder, MCS and some others, under a single, overarching disorder) was expected to be progressing, imminently, to ICD-11 field trials.

(A revision of the earlier BSS disorder name is not discussed within the editorial; nor whether any modifications to, or deviance from a “pure” BDS construct and criteria were being recommended for the purposes of field testing; nor are the alternative proposals of the S3DWG referenced or discussed; nor are the views of the Revision Steering Group on either set of proposals discussed.)

According to Lam et al (2012) and Ivbijaro and Goldberg (June 2013), the model proposed is that of “autonomic over-arousal,” which the authors consider may be responsible for most or all of the somatic symptoms that are experienced.

Again, compare with the S3DWG’s BDD construct, which makes no assumptions about aetiology and does not exclude the presence of a co-occurring physical health condition, whereas, for both Lam et al’s 2012 BSS and for Fink et al’s BDS, “If the symptoms are better explained by another disease, they cannot be labelled BDS.”

Potential for confusion between divergent disorder constructs:

The term “Bodily distress disorder” and the term “Bodily distress syndrome” (Fink et al, 2010), which is already operationalized in Denmark in research and clinical settings, are often seen being used interchangeably in the literature. For example, in this very recent editorial by Rief and Isaac [4]. Also in papers by Fink and others from 2007 onwards [5].

However, the S3DWG’s defining of a “Bodily distress disorder” construct has stronger conceptual alignment and criteria congruency with DSM-5’s SSD and poor conceptual and criteria congruency with Fink et al’s BDS. That SSD and BDS are very different concepts is acknowledged by Fink, Creed and Henningsen [6] [7].

Although the 2013 Ivbijaro and Goldberg editorial implies that Fink et al’s BDS construct was going forward to ICD-11 field testing, it is the S3DWG’s Bodily distress disorder name and construct that has been entered into the Beta draft – the construct that has stronger conceptual alignment with DSM-5’s SSD.

So the current proposals and intentions for field testing a potential replacement for the SDs remain unclear. This is severely hampering professional and consumer stakeholder scrutiny, discourse and input.

Four questions for TAG Mental Health Managing Editors:

1. Have the S3DWG sub working group, the PCCG working group and the Revision Steering Group reached consensus over a potential replacement framework and disorder construct for ICD-10’s Somatoform disorders and F48.0 Neurasthenia, and the ICD-10-PHC categories: F45 Unexplained somatic symptoms/medically unexplained symptoms, and F48 Neurasthenia?

2. Which recommendations are being progressed to international field testing and does ICD-11 intend to release the protocol or other information on finalized characteristics, diagnostic guidelines, criteria, inclusions, exclusions, differential diagnoses etc, that are planned to be used for the field tests and which would provide the level of detail lacking in the public version of the Beta drafting platform?

3. If, in the context of ICD-11 usage, the S3DWG working group’s proposal for a replacement for the Somatoform disorders remains for a disorder model with good concordance with the DSM-5 SSD construct, what is the rationale for proposing to name this disorder “Bodily distress disorder”?

4. Have the S3DWG, PCCG and Revision Steering Group given consideration to the significant potential for confusion if its replacement construct for the Somatoform disorders has greater conceptual alignment with the SSD construct but is assigned a disorder name that sounds very similar to, and is already being used interchangeably with an operationalized but divergent construct and criteria set?

This report updates on recent additions to the listing for Bodily distress disorder in the public version of the ICD-11 Beta draft.

This is an edited version of the report published on July 19.

Bodily distress disorder (BDD) is a new, single diagnostic category that has been proposed for ICD-11. It is intended to subsume the seven ICD-10 Somatoform disorders categories F45.0 – F45.9, and F48.0 Neurasthenia.

Bodily distress disorder (BDD) is the term that has been entered into the Beta drafting platform since February 2012.

It is the term and disorder construct that has been proposed by the ICD-11 Expert Working Group on Somatic Distress and Dissociative Disorders (S3DWG), which is chaired by Professor Oye Gureje [1].

Note: the term Bodily stress syndrome (BSS) (Lam et al, 2012) is an alternative disorder term and diagnostic construct that has been proposed by the ICD-11 Primary Care Consultation Group (PCCG), which is chaired by Professor Sir David Goldberg [2].

The disorder term and construct Bodily distress syndrome (BDS) has also been advanced for ICD-11 in a June 2013 editorial by Ivbijaro G and Goldberg D [3].

Neither of the terms Bodily stress syndrome (BSS) or Bodily distress syndrome (BDS) has been entered into the ICD-11 Beta draft.

+++
A Definition for category Bodily distress disorder was inserted into the Beta draft in late January 2014.

At that point, no definitions or characterizations for any of the uniquely coded BDD severity specifiers (currently, BDD, mild; BDD, moderate; BDD, severe) had been inserted.

+++
How is BDD being defined for the purposes of ICD-11?

The psychological and behavioural features that characterize Bodily distress disorder, as currently defined in the Beta draft, are drawn from the disorder conceptualizations in the 2012 Creed, Gureje paper on emerging proposals for the revision of the classification of somatoform disorders [1].

This paper sits behind a paywall but I have had a copy since it was first published.

The paper describes a disorder model that has poor concordance with Fink et al’s Bodily Distress Syndrome construct.

The 2012 Creed, Gureje paper defines BDD as:

“a much simplified set of criteria”;

eliminates the requirement that symptoms be “medically unexplained” as the central defining feature;

focuses on identification of positive psychobehavioural responses (excessive preoccupation with bodily symptoms, unreasonable illness fear, frequent or persistent healthcare utilization, activity avoidance for fear of damaging the body) in response to any (unspecific) persistent, distressing, single or multiple bodily symptom(s), resulting in significant impairment of functioning or frequent seeking of reassurance;

makes no assumptions about aetiology and in “[d]oing away with the unreliable assumption of its causality the diagnosis of BDD does not exclude the presence of (…) a co-occurring physical health condition”;

has no requirement for symptom counts, or for symptom patterns or symptom clusters from body or organ systems

– which describes a disorder framework into which DSM-5′s “Somatic Symptom Disorder (SSD)” could potentially be integrated, facilitating harmonization between a replacement for the ICD-10 Somatoform disorders and DSM-5’s new SSD.

+++
Whereas, Fink et al’s 2010 Bodily Distress Syndrome criteria are based on impairment and symptom patterns from body systems. Positive psychobehavioural features do not form part of the Fink et al criteria [4–6].

For ICD-11’s BDD, patients may be preoccupied with any bodily symptoms and the presence of a co-occurring physical health condition is not an exclusion.

But for Fink et al’s BDS, “If the symptoms are better explained by another disease, they cannot be labelled BDS.”

BDD’s three severity specifiers are proposed to be characterized on the basis of the extent to which responses to persistent, distressing symptoms are perceived as excessive and on degree of impairment, not on the basis of the number of bodily symptoms and the number of body or organ systems that are affected by the disorder.

In contrast, BDS’s two severities are based on symptom patterns (a BDS Modest, single-organ type and a BDS Severe, Multi-organ type).

Both BDD and BDS are intended to subsume the Somatoform disorders and Neurasthenia.

But BDS seeks to arrogate the so-called “functional somatic syndromes,” CFS, ME, IBS, Fibromyalgia, chronic pain disorder, MCS and some others, and subsume them under a single, overarching BDS diagnosis [6].

So although the BDD and BDS disorder names sound very similar (and the terms are sometimes seen used interchangeably), as defined in the 2012 Creed, Gureje paper and as defined by the recently inserted Beta draft Definitions, ICD-11’s BDD and Fink et al’s BDS present divergent constructs*.

It is the ICD-11 Primary Care Consultation Group‘s 2012 proposals for a “Bodily stress disorder” [2] that had stronger conceptual alignment and criteria congruency with Fink et al’s BDS.

*Discussions between Profs Creed and Fink during the Research Clinic for Functional Disorders Symposium presentations, Aarhus University Hospital, May 15, 2014, noted that Fink et al’s BDS and DSM-5’s SSD are “very different concepts.” That SSD and BDS are divergent constructs is also discussed in: Medically Unexplained Symptoms, Somatisation and Bodily Distress: Developing Better Clinical Services, Francis Creed, Peter Henningsen, Per Fink (Eds), Cambridge University Press, 2011.

Definition

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).

Definition 

Bodily distress disorder, mild is a form of Bodily distress disorder in which there is excessive attention to bothersome symptoms and their consequences, which may result in frequent medical visits. The person is not preoccupied with the symptoms (e.g., spends less than an hour per day focusing on them). Although the individual expresses distress about the symptoms and they may have some impact on his or her life (e.g., strain in relationships, less effective academic or occupational functioning, abandonment of specific leisure activities) there is no substantial impairment in the person’s personal, family, social, educational, occupational, or other important areas of functioning.

Definition

Bodily distress disorder, severe is a form of bodily distress disorder in which there is pervasive and persistent preoccupation to the extent that the symptoms may become the focal point of the person’s life, typically requiring extensive interactions with the health care system. Preoccupation with the experienced symptoms and their consequences causes serious impairment in personal, family, social, educational, occupational, or other important areas of functioning (e.g., unable to work, alienation of friends and family, abandonment of nearly all social and leisure activities). The person’s interests may become so narrow so as to focus almost exclusively on his or her bodily symptoms and their negative consequences.

Field testing of a potential replacement for the existing ICD-10 Somatoform disorders framework is expected to be conducted over the next year or two. Disorders that survive the ICD-11-PHC field tests must have an equivalent disorder in the main ICD-11 classification.

So whatever replaces the existing ICD-10-PHC categories, F45 Unexplained somatic symptoms/medically unexplained symptoms and F48 Neurasthenia, (which is also proposed to be eliminated for the ICD-11 primary care version), will need an equivalent disorder in the main classification.

International field tests across a range of primary care settings had been anticipated to start from June, last year, but there were reported delays. It isn’t known whether consensus has been reached yet over disorder construct and diagnostic criteria for use in the field tests, or whether field testing is now underway.

I cannot confirm whether ICD-11 intends to release a protocol into the public domain for whatever construct it plans to field test, or may already be field testing.

Currently, there is no publicly available protocol or other information on finalized characteristics, diagnostic guidelines, criteria, inclusions, exclusions, differential diagnoses etc. that are planned to be used for the field tests which would provide the level of detail lacking in the public version of the Beta drafting platform.

+++

So which construct does ICD-11 Revision Steering Group favour?

Although BDD (and now its three severities) have been defined within the Beta draft, much remains unclear for proposals for the revision of this section of ICD-11 Mental and behavioural disorders.

The ICD-11 Primary Care Consultation Group’s alternative 2012 Bodily stress syndrome (BSS) construct – a near clone of Fink et al’s BDS criteria but with some SSD-like psychobehavioural responses tacked on – isn’t the construct that is entered and defined within the Beta draft.

In June 2013, Prof Gabriel Ivbijaro (not, himself, a member of the PCCG) and Prof Sir David Goldberg (who chairs the PCCG) published a joint editorial in Mental Health in Family Medicine, the official journal of The World Organization of Family Doctors (Wonca) Working Party on Mental Health, for which Prof Ivbijaro is Editor in Chief.

The authors advance the position that the forthcoming revision of ICD “provides an opportunity to include BDS in a revised classification for primary care” and imply that BDS (at least at that point) was progressing, imminently, to ICD-11 field trials.

This brief editorial was embargoed from June 2013 to June 2014 and I was unable to obtain a copy until last month, but you can read it now for free and in full here: Bodily distress syndrome (BDS): the evolution from medically unexplained symptoms (MUS).

Note, firstly, that the editorial does not declare Professor Goldberg’s interest as chair of the ICD-11 Primary Care Consultation Group.

It does not clarify whether the views and opinions expressed within the editorial represent the views of the authors or are the official positions of the PCCG working group, or of the International Advisory Group for the Revision of ICD-10 Mental and Behavioural Disorders, or of the ICD-11 Revision Steering Group (RSG), or of any committees on which co-author, Prof Ivbijaro, sits or of any bodies to which Prof Ivbijaro is affiliated.

No publicly posted progress reports are being issued by ICD-11 or by either of the two groups making recommendations for the revision of this section of ICD and I do not have a second source that confirms the status of proposals as they stood in June 2013.

But taking the editorial at face value, it would appear that the PCCG had revised its earlier proposals for a BSS construct (that drew heavily on Fink et al’s BDS criteria but had included the requirement for some psychobehavioural responses) and were now recommending that the Fink et al BDS construct and criteria should progress for ICD-11-PHC field testing and evaluation, that is, using the same disorder name and (presumably) the same criteria set that is already operationalized in research and clinical settings, in Denmark.

(The rationale for the apparent revision of the earlier BSS disorder name is not discussed within the editorial; nor whether any modifications to, or deviance from a “pure” BDS construct and criteria were being recommended for the purposes of ICD-11 field testing.)

The editorial doesn’t clarify whether the PCCG, the S3DWG and the ICD-11 Revision Steering Group (RSG) had reached consensus – it does not mention the alternative proposals of the S3DWG, at all, or discuss what is entered into the Beta draft, or discuss the views and preferences of the Revision Steering Group for any of recommendations made by the two advisory groups, to date.

It is unclear whether a “pure” BDS construct (as opposed to the PCCG’s earlier BSS modification) had already gained Revision Steering Group approval for progressing to field testing, at the point the editorial was drafted, or whether Prof Goldberg was using this Wonca house journal as a platform on which to promote his own opinions and expectations, in a purely personal capacity.

Crucially, it doesn’t explain why, if a BDS-like construct were anticipated to be progressed to field trials in the second half of 2013, it is the S3DWG’s Bodily distress disorder diagnostic construct that has been listed and defined in the Beta draft for Foundation, Mortality and Morbidity, Primary Care High Resource, Primary Care Low Resource linearizations – not the PCCG’s 2012 BSS modification, or the “pure” BDS that Prof Goldberg evidently champions.

As a source of information on the current status of proposals for the revision of the Somatoform disorders this June 2013 editorial is problematic (and now also over a year out of date).

I suspect the politics between the 12 member PCCG (which includes Marianne Rosendal*), the 17 member S3DWG and the ICD-11 Revision Steering Group are intensely fraught given Professor Goldberg’s agenda for the revision of the Somatoform disorders, since fitting BDS into ICD-11 hasn’t proved to be the shoo in that Fink, Rosendal and colleagues had hoped for**, and given that BDS cannot be harmonized with DSM-5’s SSD, as they are conceptually divergent.

*Dr Marianne Rosendal (Department of Public Health, Aarhus University), who has published with Prof Per Fink, is the European representative on WONCA’s International Classification Committee. The vice-chair of the PCCG is Dr Michael Klinkman, a GP who represents WONCA (World Organization of Family Doctors). Dr Klinkman is current convenor of WONCA’s International Classification Committee (WICC) that is responsible for the development of ICPC-2.
**Presentation, Professor Per Fink, March 19, 2014 Danish parliamentary hearing on Functional Disorders. Prof Fink stated that he and his colleagues had tried to get WHO to incorporate a section for a special group of disorders where BDS could be placed that was located neither in psychiatry nor in general medicine, but had not been successful.

Requests for clarification repeatedly stonewalled:

ICD Revision has been asked several times, via the Beta drafting platform, to clarify current proposals for the framework and disorder construct for a replacement for the ICD-10 Somatoform disorders and to clarify which construct it intends to take forward to field testing. ICD Revision has also been asked to comment on the following:

“If, in the context of ICD-11 usage, the S3DWG working group’s proposal for a replacement for the Somatoform disorders remains for a disorder model with good concordance with DSM-5′s SSD construct, what is the rationale for proposing to name this disorder “Bodily distress disorder”?

“Have the S3DWG, PCCG and Revision Steering Group given consideration to the significant potential for confusion if its replacement construct for the Somatoform disorders has greater conceptual alignment with the SSD construct but is assigned a disorder name that sounds very similar to, and is already being used interchangeably with an operationalized but divergent construct and criteria set?”

No response has been forthcoming.

Lack of publicly posted progress reports by both working groups, confusion over the content of the Beta draft and ICD Revision’s failure to respond to queries from stakeholders is hampering stakeholder scrutiny, discourse and input. It is time clinicians, researchers, allied professionals and advocacy organizations demanded transparency from ICD Revision around current proposals and field trial intentions.

+++
September symposium presentation on BDD:

In September, Professor Oye Gureje (who chairs the ICD-11 Expert Working Group on Somatic Distress and Dissociative Disorders), will be presenting on Proposals and evidence for the ICD-11 classification of Bodily Distress Disorders, as part of series of symposia on the development of the ICD-11 chapter for mental and behavioural disorders, at the World Psychiatric Association XVI World Congress, in Madrid, Spain, 14–18 September 2014 [7].

Unfortunately, I cannot attend this September symposia but would be pleased to hear from anyone who may be planning to attend.

Editorial: Bodily distress syndrome (BDS): the evolution from medically unexplained symptoms (Goldberg and ICD-11-PHC)

Post #308 Shortlink: http://wp.me/pKrrB-3Uh

An editorial and four papers on the theme of medically unexplained symptoms, first published in the June 2013 issue of Mental Health in Family Medicine and embargoed until June 1, 2014, are now accessible for free at: http://www.ncbi.nlm.nih.gov/pmc/issues/229531/

Mental Health in Family Medicine is the official journal of The World Organization of Family Doctors (Wonca) Working Party on Mental Health.

The editorial: Bodily distress syndrome (BDS): the evolution from medically unexplained symptoms (MUS), is co-authored by Prof Gabriel Ivbijaro and Prof Sir David Goldberg.

Prof Ivbijaro is Editor in Chief, Mental Health in Family Medicine, a past chair of Wonca Working Party on Mental Health and was elected president elect of the World Federation of Mental Health in August 2013.

Prof Goldberg chairs the WHO Primary Care Consultation Group (PCCG) that is leading the development of the primary care classification of mental and behavioural disorders for ICD-11 (known as ICD-11-PHC).

This report sets the editorial into context.

ICD-11-PHC

ICD-11-PHC is an abridged version of the ICD-11 classification being developed for use by clinicians and (often non-specialist) health-care workers in a wide range of global primary care settings and low- and middle-income countries.

The primary care version of the ICD-11 mental and behavioural disorders chapter is being developed simultaneously with the specialty settings version. Disorders that survive the ICD-11-PHC field tests must have an equivalent disorder in the main ICD-11 classification.

The PCCG work group is developing and field testing 28 mental disorders for ICD-11-PHC, which includes making recommendations to the International Advisory Group for a potential replacement for the existing ICD-10-PHC category, F45 Unexplained somatic symptoms/medically unexplained symptoms.

A second ICD-11 working group, the Expert Working Group on Somatic Distress and Dissociative Disorders (S3DWG), is advising on the revision of ICD-10’s Somatoform disorders in parallel with the PCCG and has proposed an alternative disorder construct.

Thus far, neither working group has commented publicly on the alternative proposals presented by the other group, how the two groups interrelate, whether they are expected to reach consensus over a potential new conceptual framework to replace the existing Somatoform disorders, or to what extent consensus has been reached.

No public progress reports are being published by either group, or by the International Advisory Group, and those monitoring and reporting on the revision of these ICD-10 Chapter V categories rely on journal papers, editorials, symposia presentations, internal ICD Revision summary reports and meeting materials and on the limited content in the public version of the ICD-11 Beta drafting platform to piece together updates.

++
Does this editorial advance our understanding of current proposals?

Key point: this Ivbijaro and Goldberg editorial is now over 12 months old and should be read with the caveat that proposals by the PCCG working group may have been revised since the editorial was first published.

As a source of information on the current status of proposals by the Primary Care Consultation Group (PCCG), this editorial is problematic.

Firstly, it is over 12 months old and the PCCG’s proposals may have undergone further revision since the editorial was submitted for publication.

At the time of submission, the authors anticipated imminent field testing for ICD-11-PHC but the projected start dates for internet and clinic-based field testing, which will assess utility of proposed ICD-11 diagnostic guidelines in different types of primary care settings with particular focus on low- and middle-income countries, may be delayed. (It is on record that field tests were running behind schedule and there have been funding shortfalls, two factors in WHO’s decision, earlier this year, to shift WHA approval of ICD-11 from 2015 to 2017 to allow more time for incorporation of field test results.*)

*WICC ICPC-3 presentation, June 2013, M Klinkman, Slide 29: http://www.ph3c.org/PH3C/docs/27/000312/0000451.pdf

http://unstats.un.org/unsd/accsub/2013docs-22nd/SA-2013-12-Add1-Health-WHO.pdf

Secondly, the editorial does not declare Prof Goldberg’s interest as chair of the PCCG. It does not clarify whether the views and opinions expressed within the editorial represent the views and opinions of its authors or represent the official positions of the PCCG working group, or of the International Advisory Group for the Revision of ICD-10 Mental and Behavioural Disorders, or of the ICD-11 Revision Steering Group.

Thirdly, its brevity. This is a short editorial – not a paper:

it does not discuss the PCCG’s rationales for the changes made to its own proposals, as published in 2012.

it does not retrospectively review and compare the PCCG’s 2012 proposals for a construct which the group proposed to call, at that point, Bodily stress syndrome, with the 2012 proposals of the Expert Working Group on Somatic Distress and Dissociative Disorders (S3DWG) for an alternative construct called Bodily distress disorder.

it does not compare the PCCG’s revised proposals, as they stood in June 2013, with the S3DWG’s proposals, at that point.

crucially, it does not clarify why, if the PCCG’s June 2013 proposals were expected to be progressed to field trials, it is the S3DWG’s Bodily distress disorder diagnostic construct that has been listed and defined in the Beta draft for the Foundation, Mortality and Morbidity, Primary Care High Resource, Primary Care Low Resource linearizations.

Key points: It is difficult to disentangle the authors’ views and opinions from official position of the PCCG working group or the International Advisory Group. The editorial provides no discussion of the S3DWG’s alternative proposals or whether any consensus between the two groups had been reached. The opinions of the International Advisory Group on both sets of proposals are not discussed.

++
What new information does this June 2013 editorial provide since the 2012 Lam et al paper?

that the authors consider the Fink P, Schröder A. 2010 paper [1] provides evidence that the term Bodily Distress Syndrome has both face and content validity.

that the authors consider the concept Bodily Distress Syndrome as “a possible diagnosis that captures the range of presentations in primary care, which may be acceptable to both patient and medical professional”, for which the authors list “a range of poorly defined disorders [that include] chronic fatigue syndrome (CFS), fibromyalgia, irritable bowel syndrome (IBS), chronic pain syndrome, hyperventilation syndrome, non-cardiac chest pain and somatoform disorder.”

that the authors consider the forthcoming revision of the ICD provides an opportunity to include BDS in a revised classification for primary care, the ICD11-PHC, which is planned to be field tested in eight countries.

• that “not only has BDS replaced ‘medically unexplained symptoms’, but also ‘health anxiety’ has replaced ‘hypochondriasis'” and that the field trials “would examine whether primary care physicians wish to distinguish health anxiety (which may have few or indeed no somatic symptoms) from BDS (which by definition has at least three different somatic symptoms).”

According to the editorial, the PCCG had evidently revised its proposal for what to call its new disorder category since publication of the Lam et al paper, in 2012.

In 2012, the PCCG’s proposed term for ICD-11-PHC was Bodily stress syndrome (BSS). In this June 2013 editorial, the authors are using the term, Bodily distress syndrome (BDS).

In 2012, criteria for the PCCG’s BSS had included the requirement for psychobehavioural responses, which do not form part of the Fink et al 2010 BDS criteria – which are based on symptom patterns.

The editorial does not clarify whether, in June 2013, the PCCG (or its chair) was now advancing that the BDS construct and criteria should progress unmodified for ICD-11-PHC testing and evaluation, that is, in the form already operationalized in research and clinical settings in Denmark or would be modified for the purpose of ICD-11-PHC field trials, or to what extent.

(There is no revised criteria set included in this editorial for comparison with the detailed disorder descriptions and criteria set that had been included in Appendix 2 of the 2012 Lam et al paper.)

 Key point: The editorial provides no details or discussion of a 2013 field trial protocol. The most recent disorder descriptions, diagnostic guidelines and criteria proposed by the PCCG are not in the public domain. It is not known whether a field trial protocol has been finalized, whether or when it will be made available for public scrutiny, or whether field trials have started yet.

Two ICD Revision working groups – two sets of proposals published in 2012:

In their respective 2012 journal papers, the two working groups presented divergent conceptual proposals and neither group refers to the work being undertaken by the other group.

The 17 member Expert Working Group on Somatic Distress and Dissociative Disorders (the S3DWG) is an ICD Revision sub working group advising specifically on the revision of ICD-10’s Somatoform disorders.

Prof emeritus Francis Creed (a former DSM-5 Somatic Symptom Disorder work group member) is a member of the S3DWG, and the group is chaired by Prof Oye Gureje.

In late 2012, Creed and Gureje published a paper which had included the S3DWG’s emerging proposals for a new, single diagnostic category that would subsume the existing Somatoform disorders categories F45.0 – F45.9 and Neurasthenia [2].

The S3DWG paper sets out the group’s remit which includes:

“To provide drafts of the content (e.g. definitions, descriptions, diagnostic guidelines) for somatic distress and dissociative disorder categories in line with the overall ICD revision requirements.

“To propose entities and descriptions that are needed for classification of somatic distress and dissociative disorders in different types of primary care settings, particularly in low- and middle-income countries.”

Which suggests that the proposals the S3DWG group are advancing are also being considered for utility in primary care and low resource settings, in parallel with those recommended by the PCCG.

The S3DWG’s 2012 paper had described a disorder model which it proposed to call Bodily distress disorder (BDD).

Key point: Although the Creed, Gureje 2012 paper does not acknowledge the congruency, the BDD disorder descriptions and criteria are conceptually close to DSM-5’s new Somatic symptom disorder (SSD).

With its

“much simplified set of criteria”; no assumptions about causality; elimination of the requirement that symptoms be “medically unexplained” as the central defining feature; inclusion of the presence of a co-occurring physical health condition; focus on identification of positive psychobehavioural responses (excessive preoccupation with symptoms, unreasonable illness fear, frequent or persistent healthcare utilization, activity avoidance for fear of damaging the body) in response to any (unspecific) persistent, distressing, single or multiple bodily symptoms; and with no requirement for symptom counts or symptom patterns from body or organ systems;

the group’s BDD construct had good concordance with DSM-5’s Somatic symptom disorder (SSD) and poor concordance with Fink et al’s Bodily Distress Syndrome.

++
The PCCG’s Bodily stress syndrome (BSS):

In contrast, the PCCG’s 2012 paper [3] had described a disorder construct which it proposed to call Bodily stress syndrome (BSS), that drew heavily on Fink et al’s 2010 Bodily Distress Syndrome (BDS) disorder model [4].

BSS would replace ICD-10-PHC’s F45 Unexplained somatic symptoms/medically unexplained symptoms category. Primary care’s Neurasthenia category would also be eliminated for ICD-11-PHC.

Based (theoretically) on the “autonomic over-arousal” model, the PCCG’s BSS required symptom patterns from body systems to meet the diagnosis.

But, “If the symptoms are accounted for by a known physical disease this is not BSS.”

Which also mirrors Fink et al’s BDS – “if the symptoms are better explained by another disease, they cannot be labelled BDS. The diagnosis is therefore exclusively made on the basis of the symptoms, their complexity and duration” [4].

But the tentative BSS criteria, as presented by Lam et al, in 2012, also incorporated some DSM-5 SSD-like psychobehavioural responses, viz, “The patient’s concern over health expresses itself as excessive time and energy devoted to these symptoms.” (A straight lift from DSM-5’s SSD criteria.)

Psychological and behavioural responses do not form part of the Fink et al 2010 BDS criteria and their inclusion within BSS appeared to be a tokenistic nod towards accommodation of DSM-5’s SSD into any new conceptual framework for ICD-11. (The rationale for their insertion into an otherwise BDS-like construct is not discussed within the 2012 paper.)

Key point: In 2012, whilst highly derivative of BDS and the influence of PCCG group member, Marianne Rosendal, is clear, the proposed BSS model could not be described as a “pure” BDS model.

++
How viable is BDS for incorporation into ICD-11?

The vice-chair of the PCCG is Dr Michael Klinkman, a GP who represents WONCA (World Organization of Family Doctors). Dr Klinkman is current convenor of WONCA’s International Classification Committee (WICC) that is responsible for the development of ICPC-2.

Dr Marianne Rosendal (Department of Public Health, Aarhus University), who has published with Prof Per Fink, is the European representative on WONCA’s International Classification Committee and a member of the PCCG.

In addition to the revision of ICD-10 and ICD-10-PHC, the ICPC-2 (International Classification of Primary Care, Second edition), which classifies patient data and clinical activity in the domains of general/family practice and primary care, is also under revision.

Per Fink and colleagues have been lobbying for their Bodily Distress Syndrome construct to be integrated into forthcoming classification systems and adopted as a diagnosis by primary care practitioners.*

++
Proposed new classification

There are a number of reasons why the International Advisory Group for the Revision of ICD-10 Mental and Behavioural Disorders and the ICD Revision Steering Group might have difficulty justifying approval of any new disorder construct that seeks to arrogate the so-called “functional somatic syndromes,” CFS, IBS and Fibromyalgia, and subsume them under a new, overarching disorder category that also subsumes Neurasthenia and the Somatoform disorders.

limited independent evidence for construct validity, utility and safety of application of BDS in adults and children.

no requirements within BDS criteria for positive psychobehavioural features – location within the ICD-11 mental and behavioural disorders chapter is therefore problematic.

potential data loss, data disaggregation problems and code mapping issues resulting from loss of discretely coded terms currently located within various ICD chapters outside the mental and behavioural disorders chapter; loss of backward compatibility with ICD-10 codes and with ICD-10-CA, ICD-10-GM, ICD-10-AM and other country modifications. (Some countries may take many years to transition to ICD-11, or an adaptation of ICD-11.)

• unacceptability to patients and medical professionals

medico-political sensitivities

BDS and SSD are divergent constructs; a hybrid between BDS and SSD-like characteristics is conceptually problematic and would present difficulties if the intention is to harmonize ICD-11 with DSM-5 for this section of the classification [5].

the DSM-5 to ICD-9/ICD-10-CM cross-walk already maps DSM-5 Somatic symptom disorder to ICD-9 code 300.82 (ICD-10-CM F45.1).

It has been proposed that Somatic symptom disorder is added to the U.S.’s forthcoming clinical modification as an inclusion term to F45.1, in the Tabular List and Index.* If approved by NCHS, ICD-10-CM and ICD-11 would lack congruency if a BDS-like disorder model were incorporated into ICD-11 to replace the existing Somatoform disorders, rather than an SSD-like model.**

*September 18-19, 2013 and March 19-20, 2014 NCHS/CMS ICD-10-CM Coordination and Management Committee meetings.
**Note: since early 2009, I have strongly opposed the introduction of SSD into the DSM-5, ICD-11 and ICD-10-CM, and I am not arguing, here, in favour of an SSD-like model to replace the existing ICD-10 Somatoform disorders. There is no public domain documentary evidence that the two ICD working groups are currently considering any alternative models as potential replacements for the Somatoform disorders.

++
Has Professor Fink achieved his goal?

Disorders that survive the ICD-11-PHC field tests must have an equivalent disorder in the main ICD-11 classification.

With the criteria’s lack of positive psychobehavioural features presenting barriers for location within the ICD-11 mental and behavioural disorders chapter and with a hybrid between BDS and SSD-like features conceptually problematic, fitting BDS into ICD-11 isn’t the shoo in that Rosendal, Fink and colleagues had hoped for.

At the presentations on Functional Disorders held at the Danish parliament (March 19, 2014), Prof Fink had stated that he and his colleagues had tried to get WHO to incorporate a section for a special group of disorders where BDS could be placed that was located neither in psychiatry nor in general medicine, but had not been successful. [Creating a new ICD chapter or new parent class within an existing chapter for "interface" disorders may possibly have been proposed to ICD Revision.]*

But if a “pure” BDS (or a modification of BDS for ICD usage) is progressed to field testing over the next year or two, it should perhaps be considered whether ICD Revision has agreed to field test the PCCG’s proposal as a “straw man” construct to disprove its clinical utility, reliability and acceptability, with the intention of defaulting, after field trial evaluation, to a disorder construct that is conceptually closer to SSD, if the latter is already the preference of the International Advisory Group and the ICD Revision Steering Group.

“An overarching category of general (medical-psychiatry) interface disorders could be a helpful conceptualization for the many phenomena that are neither only somatic nor only mental [32,56,79]. The ICD-11, awaited in 2015, offers a new chance to do that. The concept of a bodily distress syndrome (BDS) offers another scientifically coherent common basis for the classification of different dimensional graduations of IBS [80].

++
WHO on Twitter:

On Feb 12, 2014, @WHO Twitter admin stated: “Fibromyalgia, ME/CFS are not included as Mental & Behavioural Disorders in ICD-10, there is no proposal to do so for ICD-11″. This position was additionally confirmed by Mr Gregory Härtl, Head of Public Relations/Social Media, WHO.

++
So what has been entered into the Beta drafting platform?

The term entered into the Beta platform (since February 2012) is Bodily distress disorder (the term favoured by the S3DWG working group) – not the term Bodily stress syndrome or Bodily Distress Syndrome.

A Definition for Bodily distress disorder was inserted around four months ago. There are no definitions or characterizations inserted yet for any of the three, uniquely coded severity specifiers (Mild; Moderate; Severe).

The psychological and behavioural features that characterize the disorder, as per the BDD Definition, are drawn from the disorder conceptualizations in the 2012 Creed, Gureje paper on emerging proposals for Bodily distress disorder which had described a disorder model with good concordance with DSM-5′s Somatic symptom disorder construct and poor concordance with Fink et al’s Bodily Distress Syndrome construct.

Key point: The term entered into the Beta drafting platform is Bodily distress disorder (the term favoured by the S3DWG working group) with a Definition based on disorder conceptualizations in the 2012 Creed, Gureje paper which had described a disorder model with good concordance with DSM-5′s Somatic symptom disorder and poor concordance with Fink et al’s Bodily Distress Syndrome construct.

++
This Dx Revision Watch post sets out (with screenshots) the most recent changes to the Beta drafting platform for the listing of BDD and the current Definition:

Forthcoming symposium presentation:

In September, Oye Gureje (chair ICD-11 Expert Working Group on Somatic Distress and Dissociative Disorders), will be presenting on Proposals and evidence for the ICD-11 classification of Bodily Distress Disorders, as part of series of symposia on the development of the ICD-11 chapter on mental and behavioural disorders, at the World Psychiatric Association XVI World Congress, in Madrid, Spain, 14–18 September 2014 [6].

++
Field testing:

Field testing on a potential replacement for the ICD-10 Somatoform disorder categories is expected to be conducted over the next couple of years. Currently, there is no publicly available protocol or other information on the finalized characteristics, diagnostic guidelines, criteria, inclusions, exclusions, differential diagnoses etc. that are planned to be used for the field tests which would provide the level of detail lacking in the public version of the Beta drafting platform.

++
Requests for clarification repeatedly stonewalled:

ICD Revision has been asked several times, via the Beta drafting platform, to clarify its current proposals for the framework and disorder construct for a replacement for the ICD-10 Somatoform disorders. ICD Revision has also been asked to comment on the following:

“If, in the context of ICD-11 usage, the S3DWG working group’s proposal for a replacement for the Somatoform disorders remains for a disorder model with good concordance with DSM-5’s SSD construct, what is the rationale for proposing to name this disorder “Bodily distress disorder”?

“Have the S3DWG, PCCG and Revision Steering Group given consideration to the significant potential for confusion if its replacement construct for the Somatoform disorders has greater conceptual alignment with the SSD construct but is assigned a disorder name that sounds very similar to, and is already being used interchangeably with an operationalized but divergent construct and criteria set?”

No clarifications have been forthcoming to date. Lack of progress reports by both working groups and the degree of confusion over the content of the Beta draft is hampering stakeholder scrutiny, discourse and input. It’s not surprising few papers have been published to date reviewing and discussing ICD Revision’s proposals for a potential replacement for the ICD-10 Somatoform disorders when information on the most recent proposals for both working groups is proving so difficult to obtain.

It’s time medical and allied professionals and advocacy organizations demanded transparency from ICD Revision for its current intentions.

Caveats:

ICD-11 Beta is a work in progress, updated daily, not finalized. Proposals for new categories are subject to ongoing revision and refinement, to field test evaluation, may not survive field testing, and are not approved by ICD Revision or WHO.

Recent changes to ICD-11 Beta drafting platform for “Bodily distress disorder”

Post #307 Shortlink: http://wp.me/pKrrB-3Ts

This post updates on further changes in the public version of the ICD-11 Beta drafting platform to the listing of proposed new ICD category, Bodily distress disorder.

Caveat: The ICD-11 Beta draft 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 International Advisory Group, the ICD Revision Steering Group and WHO classification experts. “Sorting codes” assigned to categories are subject to frequent change as chapters and categories are reorganized.

The revision of the Somatoform disorders categories has undergone a number of iterations since the release of the initial iCAT drafting platform, in May 2010.

Two working groups

The ICD-11 Expert Working Group on Somatic Distress and Dissociative Disorders (S3DWG) is one of two WHO convened groups charged with making recommendations for the revision of the ICD-10 Somatoform disorders categories.

The second group, the Primary Care Consultation Group (PCCG), leads the development of the revision of the mental and behavioural disorders for the primary care version of ICD-11, which will be known as the ICD-11-PHC.

The PCCG is making recommendations for the revision of ICD-10-PHC’s primary care diagnostic category, F45 Unexplained somatic symptoms/medically unexplained symptoms. Disorders included in the abridged primary care version will require an equivalent category within the core ICD-11 classification.

+++

What has the S3DWG work group been proposing?

The S3DWG has proposed Bodily distress disorder as a single diagnostic category to replace all of the ICD-10 Somatoform disorders between F45.0 – F45.9 and F48.0 Neurasthenia [1].

So initially, in the drafting platform, these ICD-10 legacy categories were removed.

As the Beta draft stood in mid 2013, Bodily distress disorder had been assigned three, uniquely coded severity specifiers: Mild BDD, Moderate BDD and Severe BDD. These were then reduced to just two: Bodily distress disorder and Severe bodily distress disorder.

So in January 2014, the Beta drafting platform had stood like this:

BDD at 02.02.14

Source: ICD-11 Beta drafting platform at January 29, 2014

+++

On February 18, I reported that Severe bodily distress disorder was no longer listed in the Beta drafting platform and had been replaced with the ICD-10 legacy category Somatization disorder.

I also reported that the ICD-10 category, Neurasthenia, previously proposed to be eliminated for both the ICD-11 core and Primary Care versions, had been inserted back into the Beta draft.

It was unclear how these two ICD-10 legacy categories were intended to relate to a single new diagnostic category whose conceptual framework had originally been proposed to replace both of them. The Definition texts displaying for both legacy categories had been imported unedited from ICD-10 and provided no clues to the (evidently revised) proposed framework.

So by February 2014, the draft stood like this:

BDD 240214

Source: ICD-11 Beta drafting platform at February 24, 2014

with Neurasthenia back in the draft under parent Mental and behavioural disorders:

Neurasthenia240214

Source: ICD-11 Beta drafting platform at February 24, 2014

+++
Since these changes, there have been several further modifications to the Beta draft:

Circa May 9, 2014:

Somatization disorder remained listed as a uniquely coded child category under Bodily distress disorder, with a definition comprising unedited text imported from the ICD-10 F45.0 classification.

But three uniquely coded severity specifiers had been added back in:

Bodily distress disorder, mild
Bodily distress disorder, moderate
Bodily distress disorder, severe

So by May 9, the Beta draft Joint Linearization for Mortality and Morbidity Statistics looked like this:

May_9_14_BDD

*Note that the “Sorting codes” assigned to categories change daily as chapters and category hierarchies are reorganized.

+++
Circa May 15, 2014:

Somatization disorder has now been removed from the Beta draft Linearizations as a uniquely coded child category under Bodily distress disorder.

Somatization disorder is now listed with the ICD-10 term somatoform disorders under Synonyms to Bodily distress disorder and both ICD-10 legacy terms are listed as Index Terms.

Update at June 6, 2014: The ICD-10 legacy terms, Somatoform disorders and somatization disorder are no longer listed under Index Terms to Bodily distress disorder in the Beta drafting platform or print version of the draft Alphabetical Index but remain listed under Synonyms. Both terms have been relocated under Index Terms to 6B4Z Bodily distress disorder, unspecified.

The three severity specifiers for BDD, (Mild, Moderate, Severe) remain.

So at May 27, the Beta draft Joint Linearization for Mortality and Morbidity Statistics looks like this:

May_15_14_BDD

Neurasthenia has also been removed from the Beta draft Linearizations. Nor is it listed in the PDF of the print version of the draft Alphabetical Index.

This might suggest that the most recent proposal has reverted back to eliminating Neurasthenia from ICD-11, but to retain both Somatization disorder and the term somatoform disorders under Synonyms to BDD, and as Index Terms (as opposed to retaining and coding specifically for Somatization disorder under new ICD parent term, Bodily distress disorder).

[Neurasthenia remains specified as an Exclusion to Generalized anxiety disorder (currently Chapter 06) and to Fatigue (currently Chapter 20) but this may be an oversight.]

You can view the entry for Bodily distress disorder here, in the Foundation Linearization, which also displays a Definition, Synonyms and Exclusions:

http://apps.who.int/classifications/icd11/browse/f/en#/http://id.who.int/icd/entity/767044268

(Click on the small grey arrow to the left of the BDD category term to display the three severity specifiers.)

+++

Current ICD-11 Definition:

A Definition for Bodily distress disorder was inserted around four months ago, but there are no definitions or characterizations inserted yet for any of the three severity specifiers (BDD Mild, Moderate, Severe).

The Definition for Bodily distress disorder remains the same as previously reported:

http://apps.who.int/classifications/icd11/browse/f/en#/http%3a%2f%2fid.who.int%2ficd%2fentity%2f767044268

“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).”

The psychological and behavioural features that characterize the disorder, as per this definition, are drawn from disorder conceptualizations in the 2012 Creed, Gureje paper on emerging proposals for Bodily distress disorder.

The paper described a disorder model with good concordance with DSM-5’s Somatic symptom disorder construct and poor concordance with Fink et al’s Bodily Distress Syndrome construct [1,2].

+++

In sum:

At the point of publishing this post, we can say that the public version of the Beta draft displays:

 a single Bodily distress disorder category with three uniquely coded (but as yet uncharacterized) severities replacing all the ICD-10 Somatoform disorders between F45.0 – F45.9 and ICD-10’s Neurasthenia (F48.0);

that the ICD-10 legacy terms, somatoform disorders (F45) and Somatization disorder (F45.0), are listed under Synonyms and under Index Terms to Bodily distress disorder.

Update at June 6, 2014: The ICD-10 legacy terms, Somatoform disorders and somatization disorder are no longer listed under Index Terms to Bodily distress disorder in the Beta drafting platform and print version of the Alphabetical Index but remain listed under Synonyms. Both terms have been relocated under Index Terms to 6B4Z Bodily distress disorder, unspecified.

that ICD-10’s Neurasthenia is no longer displaying in any Linearization and may remain proposed to be eliminated for ICD-11 (but remains anomalously specified in two chapters as an Exclusion term);

that an ICD-11 Definition for Bodily distress disorder has been entered into the draft, the wording for which is based on disorder conceptualizations in the 2012 paper: Creed F, Gureje O. Emerging themes in the revision of the classification of somatoform disorders. Int Rev Psychiatry. 2012 Dec;24(6):556-67.

Apart from scrutinizing the Definition, that is all we can safely determine about the current, proposed construct of Bodily distress disorder, in the context of ICD-11’s deployment of the term, solely from the content of the public version of the Beta drafting platform.

I’ll be writing more about this Definition and the 2012 proposals by both ICD-11 working groups in the next post (Post #308).

These recent changes are a good example of why the public version of the Beta drafting platform needs to be viewed with the WHO’s caveats in mind – the draft is in a state of flux, it is incomplete, it contains errors, omissions and anomalies and is subject to frequent rejiggery.

The entry for BDD may undergo further changes over the coming year or so and following field trials evaluation.

+++

iCAT ICD Collaborative authoring platform:

Note that ICD Revision staff and external editors are developing the draft on a separate, multi-authoring electronic platform called “iCAT ICD Collaborative authoring tool” — a platform considerably more technically sophisticated than the version of the draft that the public sees. In the editors’ version, more Content Model parameters display and there are tabs for change histories, category notes and discussions, and for reviews of proposals. 

So revisions to category chapter locations, hierarchies, internal and external peer review of proposals, drafting and revisions of textual content and rationales for these revisions can be tracked by users of the platform with editing rights or viewing access. The absence of this level of detail in the public version of the draft makes it very difficult for stakeholders to monitor changes and rationales for changes, or to account for missing or no longer displaying category terms.

iCAT ICD Collaborative authoring platform screencast:

This link ICD-11 iCAT screencast will open a 1:55 minute animated screencast intended as a demo for iCAT users but in the public domain. It shows the iCAT platform that the Managing Editors for the various chapters of ICD-11 are developing the draft on. Note the larger number of function tabs along the top of the screen and at 17 secs in, note the larger number of Content Model tabs load under “Details for Test 1″ in the category description pane, on the right.

What you see in the Beta draft is a cut down version for public viewing and public interaction that omits many of the functions and much of the detail of the ICD Revision iCAT platform.

To be continued in Post #308.

Global creep of DSM-5’s Somatic symptom disorder

Post #303 Shortlink: http://wp.me/pKrrB-3Qq

Update at April 14, 2014:

Written response (April 10, 2014) from Independent Hospital Pricing Authority (IHPA) to request for clarification regarding the term ‘Somatic symptom disorder’ and Australia’s clinical modification of ICD-10, ICD-10-AM:

PDF: IHPA response re SSD and ICD-10-AM


 

As previously posted:

In the previous posting Update on proposal to add DSM-5′s Somatic symptom disorder to ICD-10-CM I reported that NCHS is preparing to rubber stamp proposals to insert Somatic symptom disorder into the U.S.’s forthcoming clinical modification of ICD-10.

Comments/objections to Diagnosis Agenda proposals submitted at the March meeting need to be sent by email to NCHS at nchsicd9CM@cdc.gov by June 20th.

1] According to this Australian legislative document:

http://www.comlaw.gov.au/Details/F2014L00304

Australian Government, Statement of Principles concerning somatic symptom disorder No. 24 of 2014

for the purposes of the Veterans’ Entitlements Act 1986 and Military Rehabilitation and Compensation Act 2004

“Somatic symptom disorder attracts ICD-10-AM code F45.1.”

For the purposes of the Statement of Principles:

“ICD-10-AM code” means a number assigned to a particular kind of injury or disease in The International Statistical Classification of Diseases and Related Health Problems, 10th Revision, Australian Modification (ICD-10-AM), Eighth Edition, effective date of 1 July 2013, copyrighted by the Independent Hospital Pricing Authority, and having ISBN 978-1-74128-213-9;”

The Australian ICD-10-CM, Eighth Edition, July 2013 is not in the public domain. As I do not have access to a copy, I have contacted the relevant body for clarifications.

I have asked whether Somatic symptom disorder has been added to the Eighth Edition of ICD-10-AM as an Inclusion term to F45.1 Undifferentiated somatoform disorder in the Tabular List and Alphabetical Index.

Or, whether this legislative document relies on the ICD cross-walk codes as published in the DSM-5 in May 2013 for the cross-walk between DSM-5 disorders and the disorders in the U.S.’s ICD-9-CM and forthcoming ICD-10-CM.

Or, whether the legislative document relies on a cross-walk between DSM-5 disorders and ICD-10-AM codes developed specifically in relation to the ICD-10-AM Eighth Edition, July 2013.

I will update this post when I have received clarification.

According to this page: http://nccc.uow.edu.au/icd10am-achi-acs/overview/icd10am/index.html

“[Australia's] ICD-10-AM has also enjoyed more widespread use, having been assessed, found suitable and adopted by many other countries, including: New Zealand, Ireland, Singapore, Slovenia.”

I am unable to confirm how many countries that have adopted ICD-10-AM have migrated from earlier editions to the July 2013 edition or are preparing to migrate to the most recent edition.

Other clinical modifications (CMs) of ICD-10:

Canada (ICD-10-CA): The most recent edition of ICD-10-CA is the 2009 edition Volume One: Tabular List 2009. Canada is anticipated to adopt a CM of ICD-11 before the U.S. does, but in meantime, an updated edition of ICD-10-CA might be anticipated, especially given the recent extension to the ICD-11 development timeline. Canadians will need to be alert to the potential for addition of SSD as an inclusion term to the next edition of ICD-10-CA.

Germany (ICD-10-GM): There is an ICD-10-GM version for 2014. There is no SSD under F45.x or under any other code, but watch for any updated versions released prior to transition to a CM of ICD-11.

Thailand (ICD-10-TM): There does not appear to be a more recent version of the Thai clinical modification than the online version for 2007, but watch for SSD in any updated versions prior to potential transition to a CM of ICD-11. ICD-10-TM Online version for 2007.

ICD-11 Beta drafting platform:

There is no documentary evidence of a proposal to add SSD, per se, to ICD-11. However, the wording for the Definition for Bodily distress disorder, as it currently stands in the Beta drafting platform, is drawn from the Gureje, Creed 2012 paper on the S3DWG sub working group’s emerging proposals for ICD-11 [1].

The paper described a simplified disorder framework – a construct into which DSM-5′s Somatic Symptom Disorder could be comfortably integrated, thus facilitating harmonization between the respective ICD-11 and DSM-5 disorder construct and criteria replacements for the Somatoform disorders classifications.

As with DSM-5′s SSD, for the emerging proposals for BDD, the focus was not on symptoms counts, or on strict symptom patterns or clusters from one or more body systems, or on whether symptoms were determined as being “medically explained” or “medically unexplained,” but on the perception of disproportionate or maladaptive psychobehavioural responses to, or excessive preoccupation with any troublesome chronic bodily symptom(s). And that in doing away with the “unreliable assumption of its causality” the diagnosis of BDD would not exclude the presence of a co-occurring physical health condition – which is very close to SSD’s defining characteristics.

2] On the Patient.co.uk site, a peer reviewed article on Somatic symptom disorder:

http://www.patient.co.uk/doctor/somatic-symptom-disorder

This article is not a recommendation and it draws heavily on the DSM-IV and current ICD-10 Somatoform disorders framework, criteria and literature. Though it does highlight that DSM-5 has a new, simplified framework and reformulated criteria that rely less on strict patterns of somatic symptoms and more on the degree to which a patient’s thoughts, feelings and behaviours about their symptoms are considered disproportionate or excessive; that for DSM-5, “medically unexplained” is de-emphasized – symptoms may or may not be associated with another medical condition and patients with organic comorbidities such as heart disease, osteoarthritis or cancer, who would have previously been excluded under DSM-IV, can now be included in the diagnosis of SSD.

There is little published research examining the reliability, utility, epidemiology, clinical characteristics or treatment of Somatic symptom disorder as a diagnostic construct and none of the article’s references are for papers specifically using the new Somatic symptom disorder criteria.

Christopher Bass, consultant in liaison psychiatry, John Radcliffe Hospital , Oxford OX3 9DU

Dr Max Henderson, senior lecturer in Epidemiology and Occupational psychiatry, Inststitute of psychiatry, Kings College London 

According to the authors, fibromyalgia ( coded in ICD-10 under Chapter XXIII Diseases of the musculoskeletal system and connective tissue, at M79.7 ) is more appropriately described in terms of “polysymptomatic distress”; “polysymptomatic distress has been recognised as a somatoform disorder, specifically as a somatic symptom disorder or SSD,” and that since “FM overlaps with other disorders with medically unexplained symptoms such as irritable bowel syndrome and chronic fatigue syndrome” it is more appropriate to treat them with multidisciplinary teams within the same specialised service in the general hospital.
