A controlled treatment study of somatoform disorders including analysis of healthcare utilization and cost-effectiveness

Objective: The purpose of this prospective study was to evaluate the effects of cognitive-behavioral treatment (CBT) on mental health status and healthcare utilization in patients with somatoform disorders (SFD) of a specialized tertiary care center. Methods: According to DSM-IV interviews, 54 patients had somatization disorder (SD), 51 abridged somatization syndrome (SSI-8) and 67 other defined SFD. A clinical non-SFD comparison group consisted of 123 patients. Treatment effects were controlled against the waiting list. Cost calculations for the 2-year periods before and after treatment were based on medical and billing records from health insurance companies. Results: The SFD patients improved significantly with respect to physical symptom distress, health anxieties, dysfunctional beliefs towards body and health, depression and psychosocial functioning. Their outpatient plus inpatient charges during the 2 years prior to treatment were about 2.2-fold higher than for average patients of the health system. At the 2-year follow-up, we found treatment-related cost offset of 382 € (−24.5%) for outpatient and 1098 € (−36.7%) for inpatient care. Indirect socioeconomic costs due to days lost from work decreased by 6702 € (−35.3%). Per patient savings of 32,174 € (−63.9%) were found in a subgroup of somatizing high-utilizers. Conclusion: The results encourage including treatment strategies to reduce somatoform illness behavior into clinical practice.

Somatoform disorders in consultation-liaison psychiatry: a comparison with other mental disorders

Consultation-liaison (C-L) psychiatry has an important role in the management of somatoform disorders (SD). Characteristics of SD patients in C-L psychiatry are largely unknown and are presented in this paper. We analyzed 13,314 Dutch psychiatric consultations from 1984 to 1991 and compared patients diagnosed with SD to patients with other mental disorders and to those without a mental disorder. The comparison included socio-demographic variables, consult characteristics, medical history, current somatic morbidity, information about additional diagnostic tests, hospital admission time and aftercare management. Of the 544 SD patients 39.5% ( n = 215) were diagnosed with a conversion disorder that illustrates the highly selected nature of SD patients in C-L psychiatry. Employment among SD patients decreased significantly from 58% in the group aged 20–29 years to 6% in the group aged 50–59 years. This decrease was significantly larger as compared to other mental disorders and no mental disorders and was virtually unaffected by correction for potential confounding by gender. Contrary to our expectation no difference between the three groups was observed in claims for disability benefits. Of the SD patients 74.5% were referred for aftercare management, significantly more than the other two groups which is considered a promising development in C-L psychiatry.

Characteristics of Child Maltreatment, Psychological Dissociation, and Somatoform Dissociation of Canadian Inmates

ABSTRACT Data are presented on childhood maltreatment characteristics, psychological dissociation, somatoform dissociation, and offense types with a sample of 93 Canadian inmates (62 males and 31 females), with a mean age of 34 years (SD = 9.5). The present study includes findings based on the Child Maltreatment Interview Schedule-Short Form (CMIS-SF), the Detailed Assessment of Posttraumatic States (DAPS), the Multidimensional Dissociation Inventory (MDI), the Somatoform Dissociation Questionnaire (SDQ-20), and indices of violent and sexual offending during adulthood. Chi-square, Cohen's d, and regression analyses were conducted with the data. Results showed that women reported more childhood sexual abuse (CSA) than men, and men committed more violent and sexual offenses than women. Mean comparisons using Cohen's d statistic showed that inmates (N = 62) reported more trauma-related dissociation (DAPS) and more MDI dissociation compared to normative data for these instruments; however, inmates had lower somatoform dissociation scores when compared to published means of dissociative disorder, somatoform disorder, and eating-disorder patients. Inmates with CSA histories had higher SDQ-20 scores than those who did not. No differences were found between sex offenders and non-sex offenders in terms of probable PTSD, probable DID, MDI scales, or the SDQ-20. CSA that involved penetration predicted MDI dissociation and also predicted later sexual offending. Of the MDI scales, derealization and memory disturbance predicted sexual offending. Neither MDI scales nor any of the CMIS-SF maltreatment types predicted violent offending. Results are discussed in terms of treatment implications for incarcerated individuals with histories of child maltreatment.

Topiramate as a treatment for pain in multisomatoform disorder patients: an open trial

Multisomatoform disorder (MSD), defined as 3 or more medically unexplained, currently distressing physical symptoms in addition to a long (> or =2 years) history of somatization, is a prevalent and disabling disorder in which few pharmacological trials have been referred to in the literature. Thirty-five MSD patients from the Somatoform Disorders Unit of the Miguel Servet University Hospital, Zaragoza, Spain, with pain of more than 3 months as the main symptom, were treated with topiramate in doses ranging from 300–400 mg/day. Patients were assessed at baseline and at one and six-months follow-up with the McGill Pain Questionnaire (MPQ), Pain Visual Analogue Scale (PVAS), Clinical Global Impresión (CGI), Global Assessment Functioning (GAF) and Hospital Anxiety Depression Scale (HADS). Eight patients (22.8%) dropped from the study, 3 due to side-effects and the other 5 because of lack of efficacy. All the outcome measures showed significant improvements at one-month except the ratings on the Hospital Anxiety Depression Scale. At six-months follow-up, clinician-rated assessments (CGI and GAF) still showed significant differences with baseline but less significant than at one-month follow-up. However, patient-rated assessments (MPQ and PVAS) did not present significant differences with baseline. Despite limitations of the study, topiramate seems to be effective in treating multisomatoform disorder patients with pain as the main symptom and a controlled randomized trial in these patients appears warranted. A possible “decay effect” in patient-rated assessments with any drug in somatoform disorder patients is discussed.

Alexithymia in somatoform disorder patients with chronic pain

The prevalence of alexithymia in fifty-five motor vehicle accident survivors who had chronic pain complaints and met DSM-III-R criteria for somatoform pain disorder was 53%. Alexithymic and non-alexithymic patients did not differ on self-reports of current pain severity or in the number of pain locations. Alexithymic patients were found to use significantly more words to describe their pain, suggesting they may have a more diffuse style in communicating their pain experience.

EEG frequency analysis in conversion and somatoform disorder.

Patients with "hysterical" neurologic symptoms have long puzzled neurologists and psychiatrists. "Hysteria" has recently been subdivided into conversion and somatoform disorder. We applied computerized EEG frequency analysis to 10 patients with diagnosed conversion disorder, 10 somatoform disorder patients, and 10 control subjects. One minute EEG samples composed of 4 sec epochs were recorded from left frontal (F7-C3), right frontal (F8-C4), left posterior (T5-01) and right posterior (T6-02) derivations. Spectral power was calculated for 4 bands (0.25-4HZ, 4.25-8Hz, 8.25-13Hz, and 13.25-30Hz), and for the full frequency range. Low (0.25-8Hz) and high (8.25-30Hz) frequency bands were compared to determine high/low power ratios on the left and right (PHLL) and (PHLR), ratios of left/right front (PLRF) and posterior (PLRP) power, mean alpha frequency deviation frontally (FLRF) and posteriorly (FLRP), and mobility of left and right frontal power (MOLF and MORF). No significant differences were found between conversion disorder patients and controls in PHLL, PHLR, PLRP, and MORF. PLRF, FLRF and MOLF differed significantly between patients and controls. Power and frequency ratios of right frontal mobilities suggested a decrease in high frequency power, reduction in mean alpha frequency, and lower predominant frequency in the right frontal area in somatoform disorder patients as compared to controls, but significance was not reached. Somatoform and conversion disorder patients differed significantly in these spectral measures. These observations suggest that the two "hysterical" disorders may have distinct pathophysiology, and may be due to eventually identifiable cerebral dysfunction in some cases.

Childhood psychologic environmental exposure in women with diagnosed somatoform disorders. A case-control study.

Fifty-three female patients with diagnosed somatoform disorders (having pronounced somatic symptoms without objective somatic signs) were studied regarding childhood exposure to death, divorce, serious somatic illness and prolonged pain in members of their core family. Similar registrations were made in a control group of 53 healthy women. The two groups were compared using the case-control method. The results revealed a more frequent exposure in the somatoform disorder patients regarding all four items, and for serious somatic illness and prolonged pains the difference was statistically significant. Further elaboration of the data suggested that exposure to pain in the family was the most important of the studied factors. The findings are thought to demonstrate the environmental etiologic impact on somatoform disorders occasioned by such psychologic exposure as those registered. The possibility of a genetic etiologic implication of the findings is also discussed.
