Somatization ILO s l Enhancement of – Clinical concept of somatization l `definitions l pathophysiology l epidemiology l diagnosis – Medical management l The practical and the evidence – Communication with patient
Unexplained Illness l l How can it be explained? l l How can I be a good doctor when I can’t explain my patient’s symptoms? l l What is the evidence for effective management?
46 y/o woman from LaCrosse comes self-referred, as a new patient for the evaluation of multiple waxing and waning symptoms for more than 15 years. She comes with two bulging radiology folders and a 3 inch stack of medical records recording many normal physical exams and laboratory tests. She comes to the “U” to find out what’s wrong; “something is definitely wrong” and the other doctors “think it’s all in my head”. She is not worried about a specific condition. PMH = lots of illness; no disease. FH = not significant. Soc Hx = married twice, two young adult children, insurance office manager, “rough childhood”. ROS = very +, see following slide. PE = She looks healthy and worried. VS and full PE normal. Labs and Imaging = lots of them all normal
Somatization, a definition N Jensen The indirect, unconscious, unintentional expression (transduction) of psych. distress through illness, as an alternate to direct expressions of emotion, anxiety and depression; a dysfunction just beginning to be describable in terms of anatomy and chemistry; its reality is appreciated only via patient’s subjective experience. Described 1960s; DSM dx 1980. N Jensen
Somatization Disorder 300.81 l l A. Many physical complaints beginning before age 30 years that occur over a period of several years and result in treatment being sought or significant impairment in social, occupational, or other important areas of functioning. DSM IV
Somatization Disorder 300.81 B. B. Each of following required to have occurred at any time in course of illness: – –1. Pain in at at least four sites or functions – –2. Two GI symptoms other than pain – –3. One sexual symptom – –4. One neurological symptom.
Somatization Disorder 300.81 C C. Either of the following: – –1. Each of the symptoms ( in criterion B) cannot be fully explained by a known medical condition or direct effect of a substance. – –2. In presence of a known medical condition, the symptoms or impairment are in excess of what the disease stage would explain. l l D. Not intentionally produced / feigned.
Undifferentiated Somatoform Disorder 300.81 AKA, sub-threshold or abridged SD, or somatization syndrome l l One or more symptom – –medically unexplained, or – –beyond expectation from known pathology l l Causing distress or dysfunction Duration => 6 months
Suffering in somatoform illness l Disease l Sickness l Illness
Theoretical Mechanisms: Neurobiologic l l Variable CNS modulation of incoming sensory information, e.g., – –conversion = excessive inhibition – –somatization = inadequate inhibition. l l Melzack R & Wall P. Pain mechanisms: A new theory. Science. 1965;150:971-979 l l Wall P. The gate control theory of pain mechanisms: a re- examination and re-statement. Brain. 1978;101:1-18.

“ Pain sensitivity linked to gene” Wisconsin State Journal 1999 l l muOR: thalamus and spinal cord l l muOR density – –:: 1/pain perception – –:: morphine analgesia – –varies by individual – –varies with stress conditions Uhl GR, et al. The mu opiate receptor as a candidate gene for pain: Polymorphisms, variations in expression, nociception, and opiate responses. Proc Natl Acad Sci U S A. 1999 Jul 6;96(14):7752-7755.

Theoretical Mechanisms: Neurobiologic l l Alexithymia, a cognitive-affective disturbance characterized by difficulties in verbally expressing moods, symbols, and feelings. l l Kooiman CG. The status of alexithymia as a risk factor in medically unexplained physical symptoms. Comprehensive Psychiatry. 1998;39:152-159. – –Corpus callosum defects prevent symbolic & affective information in the right hemisphere from reaching the left hemisphere so as to be expressed in language l l TenHouten W, et.al. Alexithymia: an experimental study of cerebral commissurotomy patients and normal control subjects. Am J Psychiatry 1986;143:312-316. – –“Emotional IQ”
Theoretical Mechanisms: Social-psychological l l Psychological (nature) – –needs for nurturance & support – –“defense mechanisms” that resolve conflict l l Social-cultural (nurture) – –SICK ROLE (1° gain) – –CULTURAL CORRECTNESS l l parents (“big kids don’t cry”) l l CLINICIANS - “Balint agreement”, “this won’t hurt” l l teachers, clergy, peers, etc.
Contexts of Somatization l l normal daily experience l l highly situational l l marked individual differences l l marked cultural differences l l associated with ΨS stress associated with DSM disorders
SD: Epidemiology l l Community prevalence DSM IV – –0.2 - 2.0% for women – –~ < 0.2% for men l l Primary care prevalence – –Somatization 25 - 75% – –Somatization disorder ? – –Hypochondriasis ~3%
Impact on Personal Health l Illness behavior – Social function l Role function – Mental functioning l Sense of well being – Physical functioning l Bed days slide in development
Impact on Health Services l l 60% of primary care patients recurrently present with unexplained somatic sx. “ … the failure to provide mental health service [had] the potential of bankrupting the health care financing system due to over-utilization of primary care physicians by somatizing patients.” Rand / Permanente Study Cummings. Health Policy Quarterly 1981;1159-1175.
Impact on Physicians’ Attitudes l l Gorlin: helplessness, loss of control, inadequacy, impotence, frustration, threatened authority, anger, and guild. l l Groves: aversion, fear / counter- attack, guilt, inadequacy, malice, wish that patients would “die and get it over with”.
Medical Management Principle components l Patient education l Risk of a missed “organic” diagnosis l Medical resource conservation l Protect patient from medical injury l Use of consultants l Care for the doctor
Management: Patient Education l l Give the illness a name – –abnormal nervous system – –leaky gates, weak editing / noise filtering – –give examples from ordinary experience l l Postpone psychological interpretation – –resistance prone by nature or nurture – –hypersensitive to doubt of sx reality – –expect slow or no insight
Management: RISK of MISSED DX l l Share the diagnostic risk with patient – –Document discussion in medical record l l Systematic surveillance – –regular visits, longer duration – –careful listening for change in sx – –liberal physical exam of symptomatic parts (somatoform relationship) – –parsimonious use of tests, drugs, & surgery
Management: Resource conservation l l Limit: ER, urgent care, walk-ins, and phone calls - contract if needed. l l Raised threshold for tests, images, drugs, surgery, procedures l l Substitute old-fashioned doctoring – –empathic listening / witnessing – –liberal physical exam – –reliable, accepting, helping relationship
Management: Protect the patient l l Marginal tests – –especially invasive tests l l Marginal treatments – –toxicity – –polypharmacy l l Excess expense l l Assert your primary care role
Management: Use of Consultants l Carefully explain purpose. l Assure your ongoing commitment -- “expert advice helps me be the best possible doctor for you”. l Psychiatry consultant helps diagnose co- morbid DSM disorders. Prepare consultants so they too will judiciously use tests, procedures, drugs. Prepare consultants so they too will judiciously use tests, procedures, drugs.
Management: Caring for the doctor l These patients consume energy l Confront and cope with negative responses –learn professional emotion handling skills l Seek support of colleagues, formal or informal l Credit yourself with hard work done well with your fair share of these patients Refer to another doctor if you cannot provide state-of-the-art care for this patient. Refer to another doctor if you cannot provide state-of-the-art care for this patient.
Management that WORKS What is the Evidence ? Consult-advice CBT for patient CBT training for MD Drug Therapy

Skills Work is Next Goal 1: Increase personal awareness Goal 2: Reduce instinctive responses Goal 3: Enhance trained responses Learning Method: Reflection on action Observed action Participatory action
Skills Demonstration l 46 y/o woman who has had multiple waxing and waning sx for > 15 years. l We’ve done a complete hx & pe and reviewed large stack of tests and images. Everything we’d have wanted has been done. l Her diagnosis is very clearly Somatoform Disorder, 300.81. l We must now inform & motivate this patient for management.
Skills Practice - evaluation There are lots of good ways to communicate l Take time out anytime – For reflection – Ask for help l How well did it work? – Well enough? Why & how? – Less well? Alternative actions? l Feedback: Ask - Tell - Ask
Skills Practice l Role play is – voluntary; no one is required to do it – not real; it is simulation, practice – a rare opportunity; try something new – confidential; take some risk – play; have some fun.
Summary & Assessment l Take-home learning? l Please complete evaluations. l Thanks for coming!
END of WORKSHOP l Additional information slides follow
Usual symptoms l l Gastrointestinal (other than pain) – –nausea & bloating most common – –vomiting, diarrhea, food intolerance l l Sexual - reproductive – –women: metrorrhagia, menorrhagia, vomiting throughout pregnancy, sexual indifference – –men: “E D”, ejaculatory dysfunction, sexual indifference
Usual symptoms l l Neurological – –impaired coordination or balance – –paralysis or localized weakness – –loss of touch or pain sensation – –double vision or blindness – –deafness – –seizures – –Dissociative, e.g., amnesia – –loss of consciousness other than fainting

Impact on Health Services II l l Collyer 1979, FP: 28% visits involved emotional illness, taking 48% of his time; 3.6% families too 32% his time. l l Katon 1984: 25-75% 1° care visits were caused by somatized Ψ-S stress; these patients take time 2-4 X non-somatizing patients. l l Burnum 1985, IM: Over 3 mos. 98/909 pts. had major Ψ-S problems, 65 combined with physical disease.
Impact on Health Services III l l Regier 1984, citizens with any of 13 DSM disorders, 58% had seen their 1°MD in prior 6 mos -- used medical care 2X normal. l l NAMCS 1978 & 1985: 70% pts with DX’d DSM disorders gave a somatic complaint as CC for MD visits. l l (Regier 1978, Schurman 1985)
Impact on Physicians’ Attitude l l Katon, et.al: physicians found somatizing patients to be signif. more frustrating than other high utilizing HMO patients.
Managing Somatization l Dx: complete problem list l Doctor - patient relationship l Patient education l Cope: doctor anger, anxiety & fatigue l missed diagnosis l time & energy requirements l Conserve resources l Care for the doctor
Management First Principles l Observe adjustment responses. l DX and RX mood and anxiety disorders. l Doctor-Patient Relationship is central! –Commitment: chronic care & realistic goals –Rogerian helping relationship l accepting, empathic, congruent (Carl Rogers)

General Hospital Psychiatry 1994;16:381-7. l l A RCT-xo of MDs & somatizing patients, of consultation letter to 59 1° MDs. 73 patients reported 17% [0%*] greater physical capacity and had 21% [12%*] reduction in health care charges. Trend mental and role function. No change gen’l health or social functioning. One year follow-up.
Treatment Effects III l l Smith GR, et.al. Arch Gen Psychiatry 1995;52:238-43. l l A RCT-xo of 51 MDs and 56 Somatizing patients of consult letter with management suggestions, resulted in 33% decrease in medical and psychiatric charges and significantly improved physical functioning up to one year after trial was finished.
