Research paper thumbnail of Das Fibromyalgiesyndrom als psychosomatische Erkrankung - Empfehlungen aktueller evidenzbasierter Leitlinien zu Diagnostik und Therapie

Zeitschrift für Psychosomatische Medizin und Psychotherapie, 2013

The diagnostic label "fibromyalgia syndrome" (FMS) has been rejected by some representatives of general and psychosomatic medicine. Methods: A summary is given of the main recommendations from current evidence-based guidelines on FMS and nonspecific/functional/somatoform bodily complaints. Results: The criteria of FMS and of persistent somatoform pain disorder or chronic pain disorder with somatic and psychological factors partly overlap. They include differential clinical characteristics of persons with chronic widespread pain but without sufficiently explaining somatic factors. Not all patients diagnosed with FMS meet the criteria of a persistent somatoform pain disorder. FMS is a functional disorder, in which in most patients psychosocial factors play an important role in both the etiology and course of illness. FMS can be diagnosed by looking at the history of a typical symptom cluster and excluding somatic differential diagnoses (without a tender point examination) using the modified 2010 diagnostic criteria of the American College of Rheumatology. Various levels of severity of FMS can be distinguished from a psychosomatic point of view, ranging from slight (single functional syndrome) to severe (meeting the criteria of multiple functional syndromes) forms of chronic pain disorder with somatic and psychological factors, of persistent somatoform pain disorder or of a somatization disorder. The diagnosis of FMS as a functional syndrome/stress-associated disorder should be explicitly communicated to the patient. A therapy within collaborative care adapted to the severity should be provided. For long-term management, nonpharmacological therapies such as aerobic exercise are recommended. In more severe cases, psychotherapy of comorbid mental disorders should be conducted. Conclusions: The coordinated recommendations of both guidelines can synthesize general medical, somatic, and psychosocial perspectives, and can promote graduated care of patients diagnosed with FMS.

This study aimed to explore the quality of the doctor-patient relationship (DPR) and its association with SSS in Chinese general hospitals outpatients. This multicenter cross-sectional study assessed the quality of DPR from both the doctor's and patient's perspective in general outpatients (n=484) from 10 departments of Psychosomatic Medicine (PM), Traditional Chinese Medicine (TCM), and Biomedicine (BM). SSS was assessed with the PHQ-15. The quality of the DPR was measured with the CARE, PDRQ-9, and DDPRQ-10 questionnaires. In addition, several standard instruments were used to assess psychosocial variables such as depression, anxiety, sense of coherence and quality of life. From the doctor's perspective, patients with high SSS were rated as significantly more difficult than patients with low SSS. No differences were noted from the perspecti...

Little data are available on the illness attributions of patients with MUS in China. This cross-sectional study investigated the illness attributions of 96 patients with MUS in the outpatient departments of Psychosomatic Medicine, biomedicine (Neurology, Gynecology), and Traditional Chinese Medicine in Shanghai. Patients completed the Illness Perception Questionnaire (IPQ) for illness attribution, the Screening Questionnaire for Somatoform Symptoms, the Hospital Anxiety and Depression Scale for emotional distress, and questionnaires on clinical and sociodemographic data. The physicians also filled out a questionnaire regarding the cause of the illness (IPQ). In contrast to previous research, both physicians and patients from all three areas of medicine most frequently reported "psychological attributions." The con...

Research paper thumbnail of How can the practice nurse be more involved in the care of the chronically ill? The perspectives of GPs, patients and practice nurses

In Germany, however there is only one kind of profession assisting the physician in practices, the practice nurse. Little is known about the present involvement of practice nurses in patients' care in Germany and about the attitudes of GPs, assistants and patients concerning an increased involvement. The aim of our study was to get qualitative information on the extent to which practice nurses are currently involved in the treatment of patients and about possibilities of increased involvement as well as on barriers of increased involvement. We performed qualitative, semi-structured interviews with 20 GPs, 20 practice nurses and 20 patients in the Heidelberg area. The interviews were digitally recorded, transcribed and content-analysed with ATLAS.ti. Practice nurses are only marginally involved in the treatme...

This study aimed to assess these key features among Chinese general hospital outpatients with high levels of somatic symptoms. Methods: This multicenter, cross-sectional study evaluated four outpatient departments of internal medicine and Traditional Chinese Medicine in Beijing and Kunming and enrolled a total of 281 consecutive patients. The patients answered questionnaires concerning somatic symptom severity [Patient Health Questionnaire (PHQ-15)], illness perception (Brief Illness Perception Questionnaire), illness behavior (Scale for the Assessment of Illness Behavior), emotional distress (Hospital Anxiety and Depression Scale) and health-related quality of life (12-Item Short Form Health Survey). Subsamples reporting high scores of somatic symptom severity (PHQ-15 ≥ 10, SOM+) versus low scores (PHQ-15 b10, SOM −) were compared. Results: Twenty-eight percent (79/281) of all outpatients showed high somatic symptom severity. The strongest correlations between high somatic symptom severity and psychobehavioral variables were found for high emotional distress, female gender, living alone, low physical quality of life and high dysfunctional illness behavior. The proportion of the explained variance was 36.1%. Conclusion: In Chinese outpatients, high somatic symptom severity is frequent and associated with psychobehavioral characteristics. With the PHQ-15 cutoff of 10, SOM + patients could be differentiated from SOM− patients using these characteristics.

Methods: Studies were identified by a literature search of the databases Allied and Complementary Medicine Database, Central Register of Controlled Trials, Cumulative Index to Nursing and Allied Health Literature, PubMed, PsycINFO, and Scopus (from inception to June 30, 2013). Primary outcomes were adequate symptom relief, global gastrointestinal score, and safety. Summary relative risks (RRs) with number needed to treat (NNT) and standardized mean differences (SMDs) with 95% confidence intervals (95% CIs) were calculated using random-effects models. Results: Eight randomized controlled trials with a total of 464 patients and a median of 8.5 (7Y12) hypnosis sessions over a median of 12 (5Y12) weeks were included into the analysis. At the end of therapy, hypnosis was superior to control conditions in producing adequate symptom relief (RR, 1.69 [95% CI = 1.14Y2.51]; NNT, 5 [3Y10]) and in reducing global gastrointestinal score (SMD, 0.32 [95% CI = j0.56 to j0.08]). At long-term follow-up, hypnosis was superior to controls in adequate symptom relief (RR, 2.17 [95% CI = 1.22Y3.87]; NNT, 3 [2Y10]), but not in reducing global gastrointestinal score (SMD, j0.57 [j1.40 to 0.26]). One (0.4%) of 238 patients in the hypnosis group dropped out due to an adverse event (panic attack). Conclusion: This meta-analysis demonstrated that hypnosis was safe and provided long-term adequate symptom relief in 54% of patients with irritable bowel syndrome refractory to conventional therapy. Key words: irritable bowel syndrome, hypnosis, systematic review, meta-analysis. CI = confidence interval; HRQOL = health-related quality life; IBS = irritable bowel syndrome; RCT = randomized controlled trial; RR = relative risk; SD = standard deviation; SDC = Supplemental Digital Content; SMD = standardized mean difference.

This study assessed the relationship between SSS, QoL and psychobehavioural characteristics in Chinese general hospital outpatients. This multicentre cross-sectional study enrolled 404 patients from 10 outpatient departments, including Neurology, Gastroenterology, Traditional Chinese Medicine [TCM] and Psychosomatic Medicine departments, in Beijing, Shanghai, Chengdu and Kunming. A structured interview was used to assess the cognitive, affective and behavioural features associated with somatic complaints, independent of their origin. Several standard instruments were used to assess SSS, emotional distress and health-related QoL. Patients who reported low SSS (PHQ-15<10, n=203, SOM-) were compared to patients who reported high SSS (PHQ-15≥10, n=201, SOM+). As compared to SOM- patients, SOM+ patients showe...

The PDR Questionnaire (PDRQ-9) provides a brief measure of the therapeutic aspects of the PDR in primary care. We assessed the internal and external validity of the German version of the PDRQ-9 in a representative crosssectional German population survey that included 2,275 persons aged$14 years who reported consulting with a primary care physician (PCP). The acceptance of the German version of this questionnaire was good. Confirmatory factor analysis demonstrated that the PRDQ-9 was unidimensional. The internal reliability (Cronbach's a) of the total score was .95. The corrected item-total correlations were$.94. The mean satisfaction index of persons with a probable depressive disorder was lower than that of persons without a probable depressive disorder, indicating good discriminative concurrent criterion validity. The correlation coefficient between satisfaction with PDR and satisfaction with pain therapy was r = .51 in 489 persons who reported chronic pain, indicating good convergent validity. Despite the limitation of low variance in the PDRQ-9 total scores, the results indicate that the German version of the PDRQ-9 is a brief questionnaire with good psychometric properties to assess German patients' perceived therapeutic alliance with PCPs in public health research.

Methods: A cross-sectional cost analysis for retrospective 6 months was conducted in 294 primary care patients with MUS. Health care utilisation and loss of productivity were measured by questionnaires. SSS was measured using the "Patient Health Questionnaire 15" (PHQ-15). Direct and indirect costs and the association of costs with SSS were analysed via multiple linear regression analysis. Results: Patients with MUS had average 6-month direct costs of 1098 EUR and indirect costs of 7645 EUR. For direct costs, outpatient physician visits were the most expensive single cost category (36%), followed by pharmaceuticals (25%) and hospital stays (19%). Indirect costs were predominantly caused by productivity reduction at work (56%) followed by early retirement (29%) and acute sickness absence (14%). As compared to mild SSS, moderate SSS was not significantly associated with direct, but with indirect costs (+2948 EUR; p b .001); severe SSS was associated with increased direct cost (+658 EUR; p = .001) and increased indirect costs (+4630 EUR; p b .001). Age was positively associated with direct cost (+15 EUR for each additional year; p = .015) as well as indirect cost (+104 EUR for each additional year; p b .001). Conclusions: MUS are associated with relevant direct and even much higher indirect costs that strongly depend on SSS.

Research paper thumbnail of A new national German guideline on non-specific, functional and somatoform bodily complaints

Journal of Psychosomatic Research, 2013

ABSTRACT Objective: 4–10% of the general population and 20% of primary care patients suffer from ... more ABSTRACT Objective: 4–10% of the general population and 20% of primary care patients suffer from non-specific, functional and somatoform bodily complaints, which are responsible for high health system expenditures. Moreover vulnerability to iatrogenic effects is a common risk to these conditions. A new German guideline was developed to address these clinical and research challenges. Methods: Based on a systematic literature search and a multilevel consensus process as determined by the Association of the Scientific Medical Societies in Germany (AWMF) multidisciplinary representatives of 29 medical and psychosocial societies and one patient association were included in the process which was sponsored and coordinated by societies for Psychosomatic Medicine. Results: More than 4000 publications were analysed by nine working groups and 148 clinical suggestions and statements were approved. Although the available evidence varied in quality a strong consensus was reached on most suggestions and statements. The new guideline emphasises the common ground for the management of non-specific, functional and somatoform bodily complaints independent from diverse manifestations, levels of patient care and medical disciplines. Key aspects were the health provider’s attitudes and behaviours, therapeutic relationship and communication, biopsychosocial diagnostics and a graded as well as multidisciplinary and liaison orientated therapy. Conclusions: The new guideline marks an important improvement in the management of non-specific, functional and somatoform bodily complaints, especially in regard to health system structures and treatment standards. It furthermore identifies enormous clinical and research deficits in Germany but probably also in a European perspective.

(ii) To validate the distinctiveness of the ICD-10 to ICPC-2 conversion rule which maps ICD-10 dissociative/conversion disorder (F44) as well as half of the somatoform categories (F45.0-2) to P75 and codes the other half of these disorders (F45.3-9), including autonomic organ dysfunctions and pain syndromes, as symptom diagnoses plus a psychosocial code in a multiaxial manner. Methods: Cross-sectional analysis of routine data from a German research database comprising the electronic patient records of 32 general practitioners from 22 practices. For each P75 patient, control subjects matched for age, gender, and practice were selected from the 2007 yearly contact group (YCG) without a P75 diagnosis using a propensity-score algorithm that resulted in eight controls per P75 patient. Results: Of the 49,423 patients in the YCG, P75 was diagnosed in 0.6% (302) and F45.3-9 in 1.8% (883) of cases; overall, somatisation syndromes were diagnosed in 2.4% of patients. The P75 coding pattern coincided with typical characteristics of severe, persistent medically unexplained symptoms (MUS). F45.3-9 was found to indicate moderate MUS that otherwise showed little clinical difference from P75. Pain syndromes exhibited an unspecific coding pattern. Mild and moderate MUS were predominantly recorded as symptom diagnoses. Psychosocial codes were rarely documented. Conclusions: ICPC-2 P75 was mainly diagnosed in cases of severe MUS. Multiaxial coding appears to be too complicated for routine primary care. Instead of splitting P75 and F45.3-9 diagnoses, it is proposed that the whole MUS spectrum should be conceptualized as a continuum model comprising categorizations of uncomplicated (mild) and complicated (moderate and severe) courses. Psychosocial factors require more attention.

Research paper thumbnail of Depression, anxiety, and somatoform disorders: Vague or distinct categories in primary care? Results from a large cross-sectional study

Our main objective was to draw on the often neglected general practitioners' (GPs) perspective to investigate what characterizes these three common mental diagnoses with regard to creating more suitable categories in the DSM-V and ICD-11. Methods: We collected independent data from 1751 primary care patients (participation rate=77%) and their 32 treating GPs in Germany. Patients filled out validated patient self-report measures for depression (PHQ-9), somatic symptom severity (PHQ-15), and illness anxiety (Whiteley-7), and questions regarding coping and attribution of illness. GPs' clinical diagnoses and associated features were assessed. Results: Patients diagnosed by their GPs with depression, anxiety, and/or somatoform disorders were significantly older, less educated, and more often female than the reference group not diagnosed with a mental disorder. They had visited the GP more often, had a longer duration of symptoms, and were more often under social or financial stress. Among the mental disorders diagnosed by the GPs, depression (OR=4.4; 95% CI=2.6 to 7.5) and comorbidity of somatoform, depressive, and anxiety disorders (OR=9.5; 95% CI=4.6 to 19.4) were associated with the largest degrees of impairment compared to the reference group. Patients diagnosed as having a somatoform/functional disorder only had mildly elevated impairment on all dimensions (OR=2.0; 95% CI=1.4 to 2.7). Similar results were found for the physicians' attribution of psychosocial factors for cause and maintenance of the disease, difficult patient-doctor relationship, and self-assessed mental disorder. Conclusion: In order to make the DSM-V and ICD-11 more suitable for primary care, we propose providing appropriate diagnostic categories for (1) the many mild forms of mental syndromes typically seen in primary care; and (2) the severe forms of comorbidity between somatoform, depressive, and/or anxiety disorder, e.g., with a dimensional approach.

Health care utilisation and loss of productivity were measured by questionnaires. SSS was measured using the "Patient Health Questionnaire 15" (PHQ-15). Direct and indirect costs and the association of costs with SSS were analysed via multiple linear regression analysis. Results: Patients with MUS had average 6-month direct costs of 1098 EUR and indirect costs of 7645 EUR. For direct costs, outpatient physician visits were the most expensive single cost category (36%), followed by pharmaceuticals (25%) and hospital stays (19%). Indirect costs were predominantly caused by productivity reduction at work (56%) followed by early retirement (29%) and acute sickness absence (14%). As compared to mild SSS, moderate SSS was not significantly associated with direct, but with indirect costs (+2948 EUR; p b .001); severe SSS was associated with increased direct cost (+658 EUR; p = .001) and increased indirect costs (+4630 EUR; p b .001). Age was positively associated with direct cost (+15 EUR for each additional year; p = .015) as well as indirect cost (+104 EUR for each additional year; p b .001). Conclusions: MUS are associated with relevant direct and even much higher indirect costs that strongly depend on SSS.

Moreover vulnerability to iatrogenic effects is a common risk to these conditions. A new German guideline was developed to address these clinical and research challenges. Methods: Based on a systematic literature search and a multilevel consensus process as determined by the Association of the Scientific Medical Societies in Germany (AWMF) multidisciplinary representatives of 29 medical and psychosocial societies and one patient association were included in the process which was sponsored and coordinated by societies for Psychosomatic Medicine. Results: More than 4000 publications were analysed by nine working groups and 148 clinical suggestions and statements were approved. Although the available evidence varied in quality a strong consensus was reached on most suggestions and statements. The new guideline emphasises the common ground for the management of non-specific, functional and somatoform bodily complaints independent from diverse manifestations, levels of patient care and medical disciplines. Key aspects were the health provider’s attitudes and behaviours, therapeutic relationship and communication, biopsychosocial diagnostics and a graded as well as multidisciplinary and liaison orientated therapy. Conclusions: The new guideline marks an important improvement in the management of non-specific, functional and somatoform bodily complaints, especially in regard to health system structures and treatment standards. It furthermore identifies enormous clinical and research deficits in Germany but probably also in a European perspective.

This study aimed to assess these key features among Chinese general hospital outpatients with high levels of somatic symptoms. Methods: This multicenter, cross-sectional study evaluated four outpatient departments of internal medicine and Traditional Chinese Medicine in Beijing and Kunming and enrolled a total of 281 consecutive patients. The patients answered questionnaires concerning somatic symptom severity [Patient Health Questionnaire (PHQ-15)], illness perception (Brief Illness Perception Questionnaire), illness behavior (Scale for the Assessment of Illness Behavior), emotional distress (Hospital Anxiety and Depression Scale) and health-related quality of life (12-Item Short Form Health Survey). Subsamples reporting high scores of somatic symptom severity (PHQ-15 ≥ 10, SOM+) versus low scores (PHQ-15 b10, SOM −) were compared. Results: Twenty-eight percent (79/281) of all outpatients showed high somatic symptom severity. The strongest correlations between high somatic symptom severity and psychobehavioral variables were found for high emotional distress, female gender, living alone, low physical quality of life and high dysfunctional illness behavior. The proportion of the explained variance was 36.1%. Conclusion: In Chinese outpatients, high somatic symptom severity is frequent and associated with psychobehavioral characteristics. With the PHQ-15 cutoff of 10, SOM + patients could be differentiated from SOM− patients using these characteristics.

(ii) To validate the distinctiveness of the ICD-10 to ICPC-2 conversion rule which maps ICD-10 dissociative/conversion disorder (F44) as well as half of the somatoform categories (F45.0-2) to P75 and codes the other half of these disorders (F45.3-9), including autonomic organ dysfunctions and pain syndromes, as symptom diagnoses plus a psychosocial code in a multiaxial manner. Methods: Cross-sectional analysis of routine data from a German research database comprising the electronic patient records of 32 general practitioners from 22 practices. For each P75 patient, control subjects matched for age, gender, and practice were selected from the 2007 yearly contact group (YCG) without a P75 diagnosis using a propensity-score algorithm that resulted in eight controls per P75 patient. Results: Of the 49,423 patients in the YCG, P75 was diagnosed in 0.6% (302) and F45.3-9 in 1.8% (883) of cases; overall, somatisation syndromes were diagnosed in 2.4% of patients. The P75 coding pattern coincided with typical characteristics of severe, persistent medically unexplained symptoms (MUS). F45.3-9 was found to indicate moderate MUS that otherwise showed little clinical difference from P75. Pain syndromes exhibited an unspecific coding pattern. Mild and moderate MUS were predominantly recorded as symptom diagnoses. Psychosocial codes were rarely documented. Conclusions: ICPC-2 P75 was mainly diagnosed in cases of severe MUS. Multiaxial coding appears to be too complicated for routine primary care. Instead of splitting P75 and F45.3-9 diagnoses, it is proposed that the whole MUS spectrum should be conceptualized as a continuum model comprising categorizations of uncomplicated (mild) and complicated (moderate and severe) courses. Psychosocial factors require more attention.

Research paper thumbnail of Depression, anxiety, and somatoform disorders: Vague or distinct categories in primary care? Results from a large cross-sectional study

Our main objective was to draw on the often neglected general practitioners' (GPs) perspective to investigate what characterizes these three common mental diagnoses with regard to creating more suitable categories in the DSM-V and ICD-11. Methods: We collected independent data from 1751 primary care patients (participation rate=77%) and their 32 treating GPs in Germany. Patients filled out validated patient self-report measures for depression (PHQ-9), somatic symptom severity (PHQ-15), and illness anxiety (Whiteley-7), and questions regarding coping and attribution of illness. GPs' clinical diagnoses and associated features were assessed. Results: Patients diagnosed by their GPs with depression, anxiety, and/or somatoform disorders were significantly older, less educated, and more often female than the reference group not diagnosed with a mental disorder. They had visited the GP more often, had a longer duration of symptoms, and were more often under social or financial stress. Among the mental disorders diagnosed by the GPs, depression (OR=4.4; 95% CI=2.6 to 7.5) and comorbidity of somatoform, depressive, and anxiety disorders (OR=9.5; 95% CI=4.6 to 19.4) were associated with the largest degrees of impairment compared to the reference group. Patients diagnosed as having a somatoform/functional disorder only had mildly elevated impairment on all dimensions (OR=2.0; 95% CI=1.4 to 2.7). Similar results were found for the physicians' attribution of psychosocial factors for cause and maintenance of the disease, difficult patient-doctor relationship, and self-assessed mental disorder. Conclusion: In order to make the DSM-V and ICD-11 more suitable for primary care, we propose providing appropriate diagnostic categories for (1) the many mild forms of mental syndromes typically seen in primary care; and (2) the severe forms of comorbidity between somatoform, depressive, and/or anxiety disorder, e.g., with a dimensional approach.
