[Therapeutic Effort in Inpatient or Day Patient Treatments and Therapy Success in Patients with Depressive Disorders]. / Therapeutischer Aufwand in stationärer oder tagesklinischer Behandlung und Therapieerfolg bei Patienten mit depressiven Störungen.

Several therapeutic treatments like individual psychotherapy, group therapy, creative therapies and talks with the nursing staff are components in an inpatient psychosomatic (psychotherapeutic) treatment or a psychosomatic day hospital treatment. In Germany, these therapies have to be documented by the administration with so called OPS-Codes. These codes are reported to the Institute for Reimbursement in Hospitals (InEK). With the data of the INDDEP-study it should be investigated how the therapies of 7 hospitals and 8 day-hospitals compare to each other. In addition, it should be studied, if the amount of the documented therapies is connected to the outcome in these hospitals. In the INDDEP-study, data of patients with major depression were assessed at 4 measurement points (admission, discharge, 3 months and 12 months follow up). In addition, the OPS codes of the treatments were documented. The results show that it is possible to get a rough estimation of the psychotherapeutic doses by the OPS-codes. The results show significant differences between the hospitals in terms of the intensity and professional group composition of the treatments. This result is confirmed for in-patient and day hospital treatments. Correlation analyses showed no significant correlation between the total amount of therapy and the improvement in depressive symptoms. It is assumed that there are moderating variables (patient-, therapy and process-related) which moderate the relation between doses and outcome. This should be identified in further studies.

Diagnostic criteria for persistent postural-perceptual dizziness (PPPD): Consensus document of the committee for the Classification of Vestibular Disorders of the Bárány Society.

This paper presents diagnostic criteria for persistent postural-perceptual dizziness (PPPD) to be included in the International Classification of Vestibular Disorders (ICVD). The term PPPD is new, but the disorder is not. Its diagnostic criteria were derived by expert consensus from an exhaustive review of 30 years of research on phobic postural vertigo, space-motion discomfort, visual vertigo, and chronic subjective dizziness. PPPD manifests with one or more symptoms of dizziness, unsteadiness, or non-spinning vertigo that are present on most days for three months or more and are exacerbated by upright posture, active or passive movement, and exposure to moving or complex visual stimuli. PPPD may be precipitated by conditions that disrupt balance or cause vertigo, unsteadiness, or dizziness, including peripheral or central vestibular disorders, other medical illnesses, or psychological distress. PPPD may be present alone or co-exist with other conditions. Possible subtypes await future identification and validation. The pathophysiologic processes underlying PPPD are not fully known. Emerging research suggests that it may arise from functional changes in postural control mechanisms, multi-sensory information processing, or cortical integration of spatial orientation and threat assessment. Thus, PPPD is classified as a chronic functional vestibular disorder. It is not a structural or psychiatric condition.

Prognostic and prescriptive predictors of improvement in a naturalistic study on inpatient and day hospital treatment of depression.

BACKGROUND: The study aimed to identify prognostic (associated with general outcome) and prescriptive (associated with differential outcome in two different settings) predictors of improvement in a naturalistic multi-center study on inpatient and day hospital treatment in major depressive disorder (MDD). METHODS: 250 inpatients and 250 day hospital patients of eight psychosomatic hospitals were assessed at admission, discharge and a 3-months follow-up. Primary outcome was defined as a reduction of depressive symptomatology from admission to discharge and from discharge to follow-up (QIDS-C, total score). Percent improvement scores at discharge and at follow-up were entered as dependent variables into two General Linear Models with a set of predictor variables and the respective interaction terms with treatment setting. The selection of predictor sets was guided by statistical methods of variable preselection (LASSO). RESULTS: Three variables were associated with less improvement from admission to discharge: the number of additional axis-I diagnoses, axis-II co-morbidity (SCID) and lower motivation (expert assessment). Social support (F-SozU) predicted symptom course between discharge and 3-month follow-up. Patients with no absent / sick days prior to admission showed a less favorable symptom course after discharge when treated as inpatients. CONCLUSIONS: Patients with co-morbidity show less improvement during the active treatment phase. Motivation can be considered a prerequisite for symptom reduction, whereas social support seems to be an important factor for the maintenance of treatment gains. The lack in prescriptive predictors found may point to the fact that inpatient and day hospital treatment have comparable effects for most subgroups of patients with MDD.

Brain effects of computer-assisted cognitive remediation therapy in anorexia nervosa: A pilot fMRI study.

Poor cognitive-behavioral flexibility is considered a trait marker in anorexia nervosa (AN) that can be improved by cognitive remediation therapy (CRT). The present pilot study aimed at identifying changes in brain function potentially associated with CRT in AN. Data was obtained from a randomized, controlled trial. Twenty-four patients were assessed before and after 30 sessions of either CRT or a non-specific neurocognitive therapy. Voxel-wise analysis of whole brain functional magnetic resonance imaging was applied. Brain activation was measured during response inhibition and task switching. Although results did not reach significance, we found tentative support for CRT-related increases in brain activation in the dorsal putamen during task switching and in the dorsolateral prefrontal, sensorimotor and temporal cortex during response inhibition. These pilot findings provide viable pathways for future research on brain changes underlying CRT in AN.

Symptom course in inpatient and day clinic treatment of depression: Results from the INDDEP-Study.

BACKGROUND: In major depression (MDD), hospital treatment is an option in more severe cases or if outpatient treatment failed. Psychosomatic hospitals in Germany provide treatment programs with multimodal psychotherapy, either in an inpatient or a day hospital setting. In the context of health care research, this study aimed (1) to compare characteristics of patients treated in psychosomatic day hospitals and inpatient units, (2) to compare the effectiveness of both treatment modalities. METHODS: A naturalistic design was chosen to achieve external validity. 604 consecutive patients were assessed at admission, discharge and a 3-month follow-up. Primary outcome was defined as a reduction of depressive symptomatology (QIDS-C), secondary outcomes comprise overall functioning and quality of life. For a comparison of effectiveness, inpatient and day hospital samples were matched according to known predictors of outcome. RESULTS: The few differences found between the inpatient and day hospital sample were related to severity of depression and physical impairment. Inpatients more often got antidepressant medication. Additionally, inpatients were treated significantly longer, due to a subgroup of patients with somatic co-morbidity. There were no differences when comparing effectiveness. LIMITATIONS: When comparing treatment effectiveness, possible bias cannot be ruled out. There was no randomization or untreated control group. CONCLUSIONS: In patients with a more severe depression and somatic co-morbidity, inpatient treatment might be preferred as compared to day hospital treatment. However, most patients can be treated in both settings.

STEADFAST: Psychotherapeutic Intervention Improves Postural Strategy of Somatoform Vertigo and Dizziness.

Patients with somatoform vertigo and dizziness (SVD) disorders often report instability of stance or gait and fear of falling. Posturographic measurements indeed indicated a pathological postural strategy. Our goal was to evaluate the effectiveness of a psychotherapeutic and psychoeducational short-term intervention (PTI) using static posturography and psychometric examination. Seventeen SVD patients took part in the study. The effects of PTI on SVD were evaluated with quantitative static posturography. As primary endpoint a quotient characterizing the relation between horizontal and vertical sway was calculated (Q H/V ), reflecting the individual postural strategy. Results of static posturography were compared to those of age- and gender-matched healthy volunteers (n = 28); baseline measurements were compared to results after PTI. The secondary endpoint was the participation-limiting consequences of SVD as measured by the Vertigo Handicap Questionnaire (VHQ). Compared to the healthy volunteers, the patients with SVD showed a postural strategy characterized by stiffening-up that resulted in a significantly reduced body sway quotient before PTI (patients: Q H/V = 0.31 versus controls: Q H/V = 0.38; p = 0.022). After PTI the postural behavior normalized, and psychological distress was reduced. PTI therefore appears to modify pathological balance behaviour. The postural strategy of patients with SVD possibly results from anxious anticipatory cocontraction of the antigravity muscles.

Psychiatric comorbidity and psychosocial impairment among patients with vertigo and dizziness.

BACKGROUND: Vertigo and dizziness are often not fully explained by an organic illness, but instead are related to psychiatric disorders. This study aimed to evaluate psychiatric comorbidity and assess psychosocial impairment in a large sample of patients with a wide range of unselected organic and non-organic (ie, medically unexplained) vertigo/dizziness syndromes. METHODS: This cross-sectional study involved a sample of 547 patients recruited from a specialised interdisciplinary treatment centre for vertigo/dizziness. Diagnostic evaluation included standardised neurological examinations, structured clinical interview for major mental disorders (SCID-I) and self-report questionnaires regarding dizziness, depression, anxiety, somatisation and quality of life. RESULTS: Neurological diagnostic workup revealed organic and non-organic vertigo/dizziness in 80.8% and 19.2% of patients, respectively. In 48.8% of patients, SCID-I led to the diagnosis of a current psychiatric disorder, most frequently anxiety/phobic, somatoform and affective disorders. In the organic vertigo/dizziness group, 42.5% of patients, particularly those with vestibular paroxysmia or vestibular migraine, had a current psychiatric comorbidity. Patients with psychiatric comorbidity reported more vertigo-related handicaps, more depressive, anxiety and somatisation symptoms, and lower psychological quality of life compared with patients without psychiatric comorbidity. CONCLUSIONS: Almost half of patients with vertigo/dizziness suffer from a psychiatric comorbidity. These patients show more severe psychosocial impairment compared with patients without psychiatric disorders. The worst combination, in terms of vertigo-related handicaps, is having non-organic vertigo/dizziness and psychiatric comorbidity. This phenomenon should be considered when diagnosing and treating vertigo/dizziness in the early stages of the disease.

Persistence of symptoms in primary somatoform vertigo and dizziness: a disorder "lost" in health care?

The aim of this study was to perform a 3-year follow-up of primary somatoform vertigo and dizziness (SVD) regarding health care use and treatment. Ninety-two patients with dizziness underwent detailed vestibular neurophysiological testing and a Structured Clinical Interview for Diagnostic and Statistical Manual of Mental Disorders, Fourth Edition. Psychometric assessments comprised the Vertigo Symptom Scale, the Vertigo Handicap Questionnaire, the SCL-90-R, and the Short-Form-36 Health Survey. At the 3-year follow-up, 65 patients with primary SVD (anxiety, n = 29; depression, n = 14; somatoform disorders, n = 22) were reassessed (70.7% response). The patients improved in symptom severity (p < 0.05), handicap (p < 0.01), and physical quality of life (QoL; p < 0.05) but showed no change in emotional distress. A total of 63.1% (of n = 65) had ongoing SVD. A total of 69.2% (of n = 65) received different forms of treatments. A total of 46.1% (of n = 65) searched redundant medical diagnostic procedures. The patients with decreased coping capacity over time obtained the best prognosis. Primary SVD is an ineffectively treated disorder. Recommendations for specific complaint-oriented psychotherapy programs were given.

[Steadfast--effectiveness of a cognitive-behavioral self-management program for patients with somatoform vertigo and dizziness]. / Standfest? Erste Ergebnisse der Entwicklung eines kognitiv-verhaltenstherapeutischen Gruppenschulungsprogramms zur Behandlung des somatoformen Schwindels.

The aim of the study was to evaluate a psychotherapeutic intervention for somatoform vertigo regarding illness perception, severity and psychopathology.Patients underwent a waiting-list control group design (n=10 control group; n=14 intervention group with diagnostics at baseline, post-intervention, 3- and 12-month follow-up). Psychometric assessments comprised the Illness Perception Questionnaire, Vertigo Symptom and Handicap Questionnaire, Hospital Anxiety and Depression Scale, and Physical Health Questionnaire.The intervention group improved in personal control (p=0.046; d=0.46), and coherency (p=0.087; d=0.42). Illness beliefs in organic deteriorations could be corrected towards psychosomatic attributions.Steadfast decreased dysfunctional illness representations and increased patient empowerment.

High prevalence of mental disorders and emotional distress in patients with chronic spontaneous urticaria.

Quality of life, which is impaired in patients with chronic spontaneous urticaria (CSU), is influenced by comorbid mental disorders. The aim of this study was to assess the prevalence and spectrum of mental disorders and to determine levels of emotional distress in patients with CSU. One hundred patients with CSU were investigated for mental disorders (by specialized diagnostic interviews and psychometric instruments), levels of emotional distress (by the Global Severity Index of the Symptom Check List; SCL-90R GSI) and underlying causes of their urticaria (by dermatological assessment). Forty-eight percent of patients with CSU were diagnosed with one or more psychosomatic disorders; most common were anxiety disorders (especially phobias), followed by depressive and somatoform disorders. The use of psychometric instruments confirmed these findings. Levels of emotional distress were significantly higher and more commonly increased in patients with CSU with mental disorders. In conclusion, patients with CSU frequently experience anxiety, depression, and somatoform disorders, and these disorders are linked to increased emotional distress. These findings call for screening of patients with CSU for mental disorders in routine clinical practice as well as for controlled clinical trials.

Patients' psychological well-being and resilient coping protect from secondary somatoform vertigo and dizziness (SVD) 1 year after vestibular disease.

Secondary somatoform dizziness and vertigo (SVD) is an underdiagnosed and handicapping psychosomatic disorder, leading to extensive utilization of health care and maladaptive coping. Few long-term follow-up studies have focused on the assessment of risk factors and little is known about protective factors. The aim of this 1-year follow-up study was to identify neurootological patients at risk for the development of secondary SVD with respect to individual psychopathological disposition, subjective well-being and resilient coping. In a prospective interdisciplinary study, we assessed mental disorders in n=59 patients with peripheral and central vestibular disorders (n=15 benign paroxysmal positional vertigo, n=15 vestibular neuritis, n=8 Menière's disease, n=24 vestibular migraine) at baseline (T0) and 1 year after admission (T1). Psychosomatic examinations included the structured clinical interview for DSM-IV, the Vertigo Symptom Scale (VSS), and a psychometric test battery measuring resilience (RS), sense of coherence (SOC), and satisfaction with life (SWLS). Subjective well-being significantly predicted the development of secondary SVD: Patients with higher scores of RS, SOC, and SWLS at T0 were less likely to acquire secondary SVD at T1. Lifetime mental disorders correlated with a reduced subjective well-being at T0. Patients with mental comorbidity at T0 were generally more at risk for developing secondary SVD at T1. Patients' dispositional psychopathology and subjective well-being play a major predictive role for the long-term prognosis of dizziness and vertigo. To prevent secondary SVD, patients should be screened for risk and preventive factors, and offered psychotherapeutic treatment in case of insufficient coping capacity.

[Validation of the German version of the Vertigo Handicap Questionnaire (VHQ) in patients with vestibular vertigo syndromes or somatoform vertigo and dizziness]. / Deutschsprachige Validierung des Vertigo Handicap Questionnaire (VHQ) anhand einer Patientenstichprobe mit vestibulärem und somatoformem Schwindel.

The Vertigo Handicap Questionnaire (VHQ) by Yardley (1992) assesses physical and psychosocial impairments of vertigo or dizziness. Our study examines the structure, reliability, and aspects of validity of the German version of the VHQ. 98 vestibular vertigo syndromes vs. 90 patients with somatoform vertigo and dizziness were evaluated with the VHQ, symptom severity (VSS), distress (GSI), anxiety and depression (HADS), catastrophizing beliefs (ACQ), fear of body sensations (BSQ), and quality of life (SF-36). For diagnostic classification detailed clinical neurological, neuro-otological and psychosomatic testing were conducted. Principal components analysis identified two factors, which could be confirmed by confirmatory factor analyses: 'handicapped activity'(VHQ-ACT) and 'anxiety' (VHQ-ANX). The VHQ had good internal consistency (Cronbach's alpha: 0.92). Test-retest reliability was r = 0.80. We noted close relations between the VHQ, the VSS and measures of emotional distress as aspects of good construct validity. Together with the VSS, the VHQ completes a comprehensive diagnostic screening tool for vertigo or dizziness.

Why do subjective vertigo and dizziness persist over one year after a vestibular vertigo syndrome?

The overlap and interlinkage of dizzy symptoms in patients with psychiatric and vestibular vertigo/dizziness disorders is the subject of an ongoing debate. In a one-year follow up in 68 patients with vestibular vertigo syndromes, the persistency of vertigo and dizziness symptoms was examined and correlated with vestibular parameters and results from a psychiatric evaluation. Patients with vestibular migraine showed poorest improvement of vertigo and dizziness symptoms over time. In addition, patients who developed anxiety or depressive disorder after the onset of the vestibular disorder showed poor improvement and high persistency of symptoms.

Dizziness: anxiety, health care utilization and health behavior--results from a representative German community survey.

BACKGROUND: Due to the lack of epidemiological data on the relation of dizziness and anxiety, we investigated the prevalence of dizziness and anxiety in a representative sample of the German population. We explored the consequences of comorbid anxiety for emotional distress, functional impairment, health care utilization, and health behavior in dizziness. METHODS: By the end of 2006, we surveyed a total of 1287 persons between 14 and 90 years of age in their homes by trained interviewers with standardized self-rating questionnaires on anxiety (Patient Health Questionnaire, Generalized Anxiety Disorder Scale, Mini-Social Phobia Inventory) and dizziness (Vertigo Symptom Scale). The sample was representative for the German population in terms of age, sex, and education. RESULTS: Symptoms of dizziness were reported by 15.8% of the participants. Of the participants with dizziness, 28.3% reported symptoms of at least one anxiety disorder (generalized anxiety, social phobia, panic). Persons with dizziness reported more somatic problems such as hypertension, migraine, diabetes, etc. Comorbid anxiety was associated with increased health care use and impairment. CONCLUSION: Dizziness is a highly prevalent symptom in the general population. A subgroup with comorbid anxiety is characterized by an increased subjective impairment and health care utilization due to their dizziness. Because treatment options for distinct neurotologic disorders are also known to reduce psychological symptoms, and in order to avoid unnecessary medical treatment, early neurologic and psychiatric/psychotherapeutic referral may be indicated.

Psychiatric morbidity and comorbidity in different vestibular vertigo syndromes. Results of a prospective longitudinal study over one year.

OBJECTIVES: High rates of coexisting vestibular deficits and psychiatric disorders have been reported in patients with vertigo. Hence, a causal linkage between the vestibular system and emotion processing systems has been postulated. The aim of this study was to evaluate the impact of vestibular function and vestibular deficits as well as preexisting psychiatric pathologies on the course of vestibular vertigo syndromes over 1 year. METHODS: This interdisciplinary prospective longitudinal study included a total of 68 patients with vestibular vertigo syndromes. Four subgroups were compared: benign paroxysmal positioning vertigo (BPPV, n=19), vestibular neuritis (VN, n=14), vestibular migraine (VM, n=27), and Menière's disease (MD, n=8). All patients underwent neurological and detailed neurootological examinations as well as two standardized interviews and a psychometric examination battery at five different times (T0-T4) over 1 year. RESULTS: The prevalence of psychiatric disorders at baseline (T0) did not differ between the four subgroups. Only patients with VM showed significantly higher rates of psychiatric disorders (p=0.044) in the follow-up over 1 year. Patients with a positive history of psychiatric disorders before the onset of the vestibular disorder had significantly increased rates of psychiatric disorders compared to patients with a negative history of psychiatric disorders (T1: p=0.004, T3: p=0.015, T4: p=0.012). The extent of vestibular deficit or dysfunction did not have any influence on the further course of the vestibular disease with respect to the development of psychiatric disorders. CONCLUSION: A positive history of psychiatric disorders is a strong predictor for the development of reactive psychiatric disorders following a vestibular vertigo syndrome. Especially patients with vestibular migraine are at risk of developing somatoform dizziness. The degree of vestibular dysfunction does not correlate with the development of psychiatric disorders.

Psychiatric comorbidity in different organic vertigo syndromes.

OBJECTIVE: A high degree of psychiatric disorders has repeatedly been described among patients with organic vertigo syndromes and attributed to vestibular dysfunction. Yet almost no investigations exist which differentiate between various organic vertigo syndromes with regard to psychiatric comorbidity. The following prospective, interdisciplinary study was carried out to explore whether patients with different organic vertigo syndromes exhibit different psychological comorbidities. METHODS: 68 patients with organic vertigo syndromes (benign paroxysmal positioning vertigo (BPPV) n = 20, vestibular neuritis (VN) n = 18, Menière's disease (MD) n = 7, vestibular migraine (VM) n = 23) were compared with 30 healthy volunteers. All patients and control persons underwent structured neurological and neuro-otological testing. A structured diagnostic interview (-I) (SCID-I) and a battery of psychometric tests were used to evaluate comorbid psychiatric disorders. RESULTS: Patients with VM and MD showed significantly higher prevalence of psychiatric comorbidity (MD = 57%, VM = 65%) especially with anxiety and depressive disorders, than patients with VN (22%) and BPPV (15 %) compared to normal subjects (20 %). These elevated rates of comorbidities resulted in significantly elevated odds-ratios (OR) for the development of comorbid psychiatric disorders in general (for VM OR = 7.5, for MD OR = 5.3) and especially for anxiety disorders (for VM OR = 26.6, for MD OR = 38.7). CONCLUSION: As a consequence, a structured psychological and psychometric testing and an interdisciplinary therapy should be proceeded in cases with complex and prolonged vertigo courses, especially in patients with VM and MD. Possible reasons of these unexpected results in VM and MD are discussed.

[When the soul is out of balance]. / Somatoformer Schwindel. Wenn die Seele die Balance stört.

Vertigo is among the most common symptoms in patients visiting the doctor's office. In approximately one-third to one-half of patients suffering from chronic unclear vertigo, psychosomatic disorders are present. In complex cases of vertigo, a differential diagnostic search for psychosomatic causes is mandatory, since timely psychotherapeutic and/or psychopharmacological treatment can prevent the condition from becoming chronic. In one-third of patients with organic vertigo, somatoform vertigo may subsequently develop, the diagnosis of which is then often delayed.

Frequency of ICD-10 factitious disorder: survey of senior hospital consultants and physicians in private practice.

The authors surveyed physicians for frequency estimates of factitious disorder among their patients. Twenty-six physicians in independent practice and 83 senior hospital consultants in internal medicine, surgery, neurology, and dermatology participated. They completed a questionnaire including the estimated 1-year prevalence of factitious disorder among their patients. Frequency estimates averaged 1.3% (0.0001%-15%). The number of patients treated correlated negatively with frequency estimates. Dermatologists and neurologists gave the highest estimations. One-third of the physicians rated themselves as insufficiently informed. Frequency estimations did not differ by information level. The estimated frequency is substantial and comparable to earlier findings. Authors discuss clinical implications.
