DSM-5 Somatic Symptoms Work Group submissions 2012: Last chance to tell SSD Work Group why it needs to ditch unsafe and scientifically flawed proposals

Post #165 Shortlink: http://wp.me/pKrrB-26q

Under the guise of “eliminating stigma” and eradicating “terminology [that] enforces a dualism between psychiatric and medical conditions” the American Psychiatric Association appears hell bent on colonising the entire medical field by licensing the application of a mental health diagnosis to all medical diseases and disorders.

 

Last chance to tell the SSD Work Group why it needs to ditch its unsafe and scientifically flawed proposals

The third DSM-5 Development public review of proposals for revisions to DSM-IV categories and criteria runs through May 2 – June 15. This will be the last opportunity for stakeholders to submit feedback.

Register on the DSM-5 Development site to submit comment or use your previous user name and log in details if you submitted during the earlier reviews. For information on registration see this post from 2011.

One again, I’m collating copies of submissions to the Somatic Symptom Disorders Work Group on a dedicated page from international patient organizations, medical, allied health and other professional stakeholders, patients, advocates and professional bodies.

Any consumer groups, medical professionals, allied health professionals, social workers, lawyers etc with concerns for the Somatic Symptom Disorders proposals are welcome to forward copies of submissions for publication here.

If you are looking for submissions for the first and second public reviews, you need these pages:

Today I am publishing UK patient and advocate, Peter Kemp’s submission to the SSD Work Group:

Submission from Peter Kemp, UK advocate

How people with M.E. and CFS (and other illnesses) could be misdiagnosed as Somatic Symptom Disorder using DSM-5

Misdiagnosis is a common occurrence by all accounts. Therefore medical definitions or criteria should not only assist diagnosis – they should positively aim to prevent or reduce misdiagnosis.

Somatic Symptom Disorder (SSD) as proposed for DSM-5 allows too many possibilities for misdiagnosis. Misdiagnosis that could have disastrous consequences. This is so readily foreseeable that this must be addressed.

Once a physician diagnoses SSD, they have effectively judged the patient incompetent to interpret their own symptoms. If the patient has an unrecognised disease that progresses, or develops a new disease and reports the new symptoms to the doctor, what will the doctor do? The patient is untrustworthy. The doctor is busy and has ‘real’ patients to treat.

It is inevitable that even patients that are correctly diagnosed with SSD will sooner or later present with actual physical disease. The diagnosis of SSD could predictably obstruct investigation and treatment of their disease. This obstruction could be directly attributed to the use of an SSD diagnosis.

SSD should not be included in DSM-5 unless specific guidance to prevent misdiagnosis are included and these have been proven effective.

Imagine a doctor with a patient presenting in the early stages of MS. MS can be difficult to diagnose. When Professor Poser reviewed 366 MS diagnoses made by board certified neurologists, he found that only 65% had been correctly diagnosed (http://www.cfids.org/archives/2000rr/2000-rr4-article03.asp ).

It can take years before the signs, symptoms and tests are clear enough to make a diagnosis (http://ms.about.com/popular.htm ). The symptoms of ‘pre-diagnosis’ MS can be very distressing and the lack of a laboratory test or firm diagnosis may add to a patient’s worries. The patient may try all sorts of strategies to try and find out about, and improve what is happening to them. They may appear to pester their GP, they may appear neurotic and irrational.

Now imagine that in accordance with DSM-5, a doctor gives them a diagnosis of the proposed SSD. The patient has an official diagnosis in their medical records that amounts to ‘hypochondriac’. What effect will that have on the patient’s chances of getting the necessary investigations as the disease progresses? How is it going to help them to cope with their distressing physical symptoms now they have been explained as psychosomatic? The time it will take for them to get a true diagnosis may be further prolonged, and the years spent waiting could be made even more harrowing because of inaccurate psychological labelling.

Therefore sensible doctors will avoid diagnosing SSD. Foolish doctors risk spending their time at professional disciplinary hearings and in court; and this still might not adequately reflect the amount of suffering their diagnosis of SSD could cause.

The rationale for SSD also states: The proposed classification for Somatic Symptom Disorders deemphasizes the central role of medically unexplained symptoms. Instead, it defines disorders on the basis of positive symptoms (distressing somatic symptoms + excessive thoughts, feelings, and behaviors in response to these symptoms).”

I believe it safe to say that ‘positive symptoms’ does not mean ‘good symptoms’ or ‘symptoms with the right attitude’. I imagine it means definite, definable, testable and maybe even measurable. But when terms like ‘distressing’ and ‘excessive’ are used to measure symptoms, the definition is not a definition. It is not even a convincing concept.

The idea is right, to base the definition on signs and symptoms that are actually present, as long as these sufficiently differentiate the condition from other conditions and do not lead to too many misdiagnoses. Unfortunately, they would predictably fail to achieve this because the definition proposed is significantly subjective.

The ‘DSM-5 Proposed Revision’ could certainly misdiagnose M.E. This would be a serious matter as M.E. is classified by the WHO ICD as a neurological illness. A doctor whose diagnosis of SSD was contradicted by a doctor that diagnosed M.E could find themselves in an awkward legal situation. The implications to the proper care of a patient, due to misdiagnosing a serious neurological illness as a neurotic illness hardly bear thinking about. Hindering necessary investigations and treatment might only be a small part of the problems this might create.

The latest proposal states:

Somatic Symptom Disorder

Criteria A, B, and C must all be fulfilled to make the diagnosis:”

“A. Somatic symptoms: One or more somatic symptoms that are distressing and/or result in significant disruption in daily life.”

The Myalgic Encephalomyelitis: International Consensus Criteria – states:
(http://www.meassociation.org.uk/?p=7173)

“A patient will meet the criteria for post-exertional neuroimmune exhaustion (A), at least one symptom from three neurological impairment categories (B), at least one symptom from three immune/gastro-intestinal/genitourinary impairment categories (C), and at least one symptom from energy metabolism/transport impairments (D).”

The Canadian Expert Consensus Panel Clinical Case Definition for ME/CFS states:
(http://www.cfids-cab.org/MESA/ccpccd.pdf)

“A patient with ME/CFS will meet the criteria for fatigue, post-exertional malaise and/or fatigue, sleep dysfunction, and pain; have two or more neurological/cognitive manifestations and one or more symptoms from two of the categories of autonomic, neuroendocrine and immune manifestations; and adhere to item 7.”

Therefore every patient with M.E. or CFS or ME/CFS will present with ample distressing and disruptive symptoms to satisfy DSM-5 Somatic Symptom Disorder Part A.

“B. Excessive thoughts, feelings, and behaviors related to these somatic symptoms or associated health concerns: At least one of the following must be present.

(1) Disproportionate and persistent thoughts about the seriousness of one’s symptoms.
(2) Persistently high level of anxiety about health or symptoms
(3) Excessive time and energy devoted to these symptoms or health concerns”

The NICE Guidelines for CFS/ME state:
(http://www.nice.org.uk/nicemedia/live/11824/36191/36191.pdf )

“People with mild CFS/ME are mobile, can care for themselves and can do light domestic tasks with difficulty. Most are still working or in education, but to do this they have probably stopped all leisure and social pursuits. They often take days off, or use the weekend to cope with the rest of the week.”

Therefore even the mildest form of CFS sees persons who have often greatly reduced or stopped socializing, hobbies, sports etc.; and spend much of the time formerly devoted to these pursuits in resting and recuperating their energy to continue working.

When this level of disruptive illness goes on for more than 6 months, people will naturally and rationally become worried. They will be fearful of what is happening and what is going to happen. They will be anxious about their responsibilities, their job, their family and friend connections – everything. They may quite naturally seek help from their GP. They may be given antidepressants, sleeping medications, pain killers, etc. All these combined with a chronic illness necessitate frequent visits to their GP. They may try alternative therapies (possibly after having found what their GP offered did not help them). They may alter their diet, take nutritional supplements, go for acupuncture, homeopathy or other type of therapy.

And here is the rub; if one does not believe they are actually physically ill, their ‘thoughts, feelings and behaviours’ will certainly appear ‘excessive’. This could apply not just to CFS, but many other high impact and distressing illnesses.

The ‘Rationale’ for SSD states: “Undifferentiated Somatoform Disorder has such a low threshold that it is applicable to a very large proportion of patients attending primary care. The same low threshold issue occurs with Somatoform Disorder NOS.”

The proposed definition does not address this problem. It might actually make it worse. If doctors believe that SSD has a valid definition they may start actually using it – then God help us.

If a person with just ‘mild’ CFS is justified in being worried, justified in resting so they can keep working, justified in searching for something that will improve their health – then anyone with the illnesses mentioned could meet the criteria to satisfy DSM-5 Somatic Symptom Disorder Part B.

The only proviso is that to some extent this could depend on interpretation of the subjective aspects of part B (there may be more detailed explanations elsewhere – this essay is based on what is included here). What is ‘excessive’, ‘persistantly’, ‘disproportionate’, ‘seriousness’?*

The same ‘Rationale’ for SSD remarks on: “The lack of positive psychological features in the definition”. Unfortunately the proposed criteria attempt to define “positive psychological features” based entirely upon a physician’s subjectivity. That is not, in any sense, a definition.

This is why I believe the circular-reasoning trap constructed with SSD makes it risible. They construct a concept for SSD. They construct criteria for the concept. Chicken-egg or egg-chicken, take your pick.

The problem with this approach is that it does not IDENTIFY the psychological condition they are trying to define. SSD cannot exist only by differentiating features, this is true. Yet differentiating is an essential step. SSD must discern from other anxiety or depressive disorders. It must be discern from normal or rational anxiety, whether that anxiety is acute, chronic or fluctuating. It must discern from anxiety or depressive disorders due to neurological illness or injury. It must discern from physical illness that has not yet been diagnosed, or from physical illness for which diagnosis is complex or often delayed. It must discern from new or emerging diseases. If SSD cannot discern from these, then misdiagnosis could be a common and predictable result.

The criteria should define the disorder but they don’t. They attempt to define the criteria. The disorder should inform the criteria, but it doesn’t. The disorder is lost in a confusion of subjective terms, ‘excessive’, ‘persistantly’, ‘disproportionate’, ‘seriousness’.

The only way it can work is if someone (and here’s another trap); someone who believes that SSD exists and is defined by the DSM, decides what ‘excessive’ and ‘disproportionate’ etc., mean. Then all they have to do, is reach exactly the same conclusion that every other physician using the DSM would reach in the same position. Bingo. A diagnosis that does not mean anything other than what the ‘diagnoser’ decides that it means. And they better hope they got it right, otherwise a good lawyer will wipe the floor with them.

“C. Chronicity: Although any one symptom may not be continuously present, the state of being symptomatic is persistent (typically >6 months).”

This is either synchronicity, or they got this direct from the NICE Guidelines for ‘CFS/ME’. The NICE Guidelines ‘Making a diagnosis’ state:

“The range of presenting symptoms is wide, and fatigue and pain may not always be the prominent disabling features at initial presentation.”

“Symptoms tend to vary in intensity and type over a period of weeks or months (and evolve into what is more clearly CFS/ME with time)”

Mild CFS will satisfy DSM-5 Somatic Symptom Disorder Part C. Therefore every person with M.E. or CFS could get a diagnosis of SSD unless they can convince any psychiatrist they encounter that they are not ‘excessive’, ‘persistent’, ‘disproportionate’, or that they don’t believe they are seriously ill.

A serious anomaly might arise with SSD in both M.E. and CFS. These illnesses can start with only fatigue or just a few symptoms. Extreme fatigue and pain might be all that a patient reports. However, if the illness continues over years, some symptoms may improve whilst new ones appear. Problems such as sensory impairments, bladder and bowel problems, immune dysfunction, and a host of neurological symptoms (to name but a few) can develop.

Will the M.E. or CFS patient then be vulnerable to having their previous diagnosis ‘cancelled-out’ by a new diagnosis of SSD, because they developed too many symptoms and are worried about them?

The SSD development group have repeated previous flaws they identified as creating the need for new definitions. They have not defined anything. Yet there may be some positive outcome from their efforts. I imagine that some medical insurance company executives must be rubbing their hands together in glee, but medical negligence lawyers should be turning cartwheels.

*Editor: Accompanying the first and second release of draft proposals for the Somatic Symptom Disorders categories, two quite lengthy PDF documents that expanded on the disorder descriptions and validity/rationales were published in conjunction with the webpage Proposed Revision, Rationale and Severity texts.

For this third draft, no PDFs have been published that reflect the Work Group’s revisons since release of the second draft, last May, or set out its rationales in detail. No draft DSM-5 textual content, more comprehensive disorder descriptions or field trial evaluations are available for public scrutiny other than brief, revised Rationale texts:

Criteria for Proposed Revision J00 Somatic Symptom Disorder

One Response to DSM-5 Somatic Symptoms Work Group submissions 2012: Last chance to tell SSD Work Group why it needs to ditch flawed, unsafe and unscientific proposals

  1. Tami says:

    I was diagnosed with CFS by top CFS Dr David Bell last year. My condition has worsened and now a Dr in my home state has wrongly diagnosed me with somatoform disorder resulting in much pain and suffering
    and financial problems. This type of negligence and betrayal by the medical community has to be stopped. This syndrome is disabling enough for some without further suffering caused by medical professionals ignorant of the symptoms caused by severe CFS/ME. I would like to seek litigation in relation to this but am unsure how to go about it. I have no quality of life thanks to this Dr that met with me for one hour and would not even let me speak.
    If you have CFS be very careful who you seek care from esoeciallly those in psychiatry.
