The somatoform disorders: 6 characters in search of an author

[Conclusion instead of exclusion-The clinical diagnosis of functional movement disorders]

Functional neurological movement disorders are common in neurological practice and lead to a high degree of impairment and chronification. Affected patients usually receive a diagnosis with considerable delay and often do not get disease-specific treatment. The reasons for this delay are related to extensive diagnostic measures to exclude other nonfunctional neurological diseases. As a consequence, functional movement disorders are typically communicated as diagnoses of exclusion, which makes it difficult for patients to understand and accept the diagnosis. This is particularly unfortunate, because in the majority of patients the diagnosis can be made with confidence based on clinical features, i.e., inconsistency and incongruence. The clarification of the symptoms and the resulting treatment options should be supplemented by patient-friendly explanations of the pathophysiological basis of the disease. In this way, patients are enabled to understand and accept the diagnosis. Moreover, it can put an end to the search for a diagnosis, which can sometimes take decades, and paves the way for treatment. Thus, the diagnosis by exclusion itself becomes the starting point for treatment and can itself have a therapeutic effect.

Influence of resilience on the relations among acculturative stress, somatization, and anxiety in latinx immigrants

OBJECTIVE

In cultures where psychological distress is stigmatized, the presentation of emotional distress as somatic complaints is a frequent occurrence. Understanding factors that contribute to the presentation of somatization in Latinx immigrants is crucial due to its tie to poor quality of life. The purpose of this study was to explore relations among acculturative stress, anxiety, somatization, and resilience in a sample of Latinx immigrants living in the United States.

METHODS

Data were collected from 204 Latinx immigrants across diverse community settings.

RESULTS

Acculturative stress was positively related to both anxiety and somatization, and the relation between acculturative stress and somatization occurred through anxiety. Resilience moderated the relations between acculturative stress and somatization, and between anxiety and somatization.

CONCLUSION

This study suggests that Latinx immigrants presenting with somatic symptoms may benefit from the examination of a possible comorbid presentation of anxiety or acculturative stressors. An integrated behavioral healthcare approach is recommended when working with Latinx immigrants evaluating the impact of minority stressors on health. Clinicians are encouraged to incorporate cultural protective factors that reinforce the development and sustenance of resilience.

Psychotherapists' perspective on the treatment of patients with somatic symptom disorders

OBJECTIVE

Guidelines recommend psychotherapy in addition to primary care for patients with moderate to severe somatic symptom disorders. While general practitioners' experiences have been well studied, psychotherapists' experiences with this patient group and the explanatory models psychotherapists use in psychotherapy are unknown.

METHODS

Semi-structured qualitative interviews were conducted between April and July 2018 with 20 German licensed outpatient psychotherapists with either a medical or a psychological background, using the label "somatoform disorders". Interviews were analyzed applying thematic analysis.

RESULTS

Psychotherapists experienced management of affected patients as challenging and partly frustrating, mainly due to the difficult diagnostic process and the "somatic fixation" of some patients. Diagnostic labelling was considered a delicate issue, with some psychotherapists using the term "somatoform", while others preferred either "functional" or vague descriptions like "psychosomatic". The explanatory process was deemed essential for treatment, as was the adaptation of explanations to both a patient's biography and language. As main explanatory factors, psychotherapists referred to generic vulnerability factors, previous somatic illness and health care system influences.

CONCLUSIONS

Explanatory models used in psychotherapy are patient-centred, processual and constitute a major component of the psychotherapeutic process. However, this process might be impeded if patients are confronted with different diagnostic labels and explanatory models during their pathways through care.

Prevalence of DSM-5 somatic symptom disorder in Chinese outpatients from general hospital care

OBJECTIVE

We aimed to explore the prevalence of somatic symptom disorder (SSD) according to DSM-5 criteria in Chinese outpatients from general hospital departments.

METHODS

This multicentre cross-sectional study enrolled 699 patients from outpatient departments, including the neurology, gastroenterology, Traditional Chinese Medicine [TCM] and psychosomatic medicine departments, in five cities in China. The structured clinical interview for DSM-5 (SCID-5) for SSD was administered by trained clinical professionals to diagnose SSD.

RESULTS

SSD was diagnosed in 33.8% (236/697) of all enrolled patients. The prevalence of SSD differed significantly among the departments (χ² = 34.049, df = 2, p ≤0.001). No differences were found between SSD patients and non-SSD patients in terms of gender, residence, marital and living statuses, family income, education, employment status and lifestyle factors. However, patients with SSD reported higher levels of depression, health-related and general anxiety, lower physical and mental quality of life, higher frequency of doctor visits, increased time devoted to physical symptoms and longer duration of somatic symptoms. In a binary linear regression analysis, SSD was significantly associated with an increase in health-related anxiety, time devoted to symptoms and impact of somatic symptoms on daily life. The explained variance was Nagelkerke R² = 0.45.

CONCLUSION

There is a high prevalence of SSD in Chinese general hospital outpatient clinics. The diagnosis is associated with high levels of emotional distress and low quality of life. There is a danger of over-diagnosis if we include the mild and moderate forms of SSD. Future studies are warranted to investigate the prevalence of SSD in inpatient departments and the development of psychological interventions for these patients.

Predictors of Seeking Psychotherapy in Primary Care Patients with High Somatic Symptom Burden

Many primary care patients with high somatic symptom burden do not initiate mental health treatment. Using a cross-sectional design, this study aimed to identify predictors of psychotherapy seeking behavior for patients with high somatic symptom burden within the last 12 months. Data from 20 primary care practices were analyzed. Patients with high somatic symptom burden were identified using the Patient Health Questionnaire, structured interviews, and information from primary care physicians (PCPs). Within the final sample of 142 patients, 54 (38.03%) had been seeking psychotherapy. More severe somatic symptoms, taking psychopharmacological medication and frequently discussing psychosocial distress with PCPs, were associated with psychotherapy seeking behavior. Depressive and anxiety symptoms, and whether PCPs had diagnosed a somatoform disorder or recommended psychotherapy, were not. The results underline the importance of patient-related factors in psychotherapy seeking behavior.

Coding of medically unexplained symptoms and somatoform disorders by general practitioners - an exploratory focus group study

BACKGROUND

Medically unexplained symptoms (MUS) and somatoform disorders are common in general practices, but there is evidence that general practitioners (GPs) rarely use these codes. Assuming that correct classification and coding of symptoms and diseases are important for adequate management and treatment, insights into these processes could reveal problematic areas and possible solutions. Our study aims at exploring general practitioners' views on coding and reasons for not coding MUS/somatoform disorders.

METHODS

We invited GPs to participate in six focus groups (N = 42). Patient vignettes and a semi-structured guideline were used by two moderators to facilitate the discussions. Recordings were transcribed verbatim. Two researchers analyzed the data using structuring content analysis with deductive and inductive category building.

RESULTS

Three main categories turned out to be most relevant. For category a) "benefits of coding" GPs described that coding is seen as being done for reimbursement purposes and is not necessarily linked to the content of their reference files for a specific patient. Others reported to code specific diagnoses only if longer consultations to explore psychosomatic symptoms or psychotherapy are intended to be billed. Reasons for b) "restrained coding" were attempting to protect the patient from stigma through certain diagnoses and the preference for tentative diagnoses and functional coding. Some GPs admitted to c) "code inaccurately" attributing this to insufficient knowledge of ICD-10-criteria, time constraints or using "rules of thumb" for coding.

CONCLUSIONS

There seem to be challenges in the process of coding of MUS and somatoform disorders, but GPs appear not to contest the patients' suffering and accept uncertainty (about diagnoses) as an elementary part of their work. From GPs' points of view ICD-10-coding does not appear to be a necessary requirement for treating patients and coding might be avoided to protect the patients from stigma and other negative consequences. Our findings supply a possible explanation for the commonly seen difference between routine and epidemiological data. The recent developments in the DSM-5 and the upcoming ICD-11 will supposedly change acceptance and handling of these diagnoses for GPs and patients. Either way, consequences for GPs' diagnosing and coding behavior are not yet foreseeable.

Diagnostic barriers for somatic symptom disorders in primary care: study protocol for a mixed methods study in Germany

INTRODUCTION

Somatoform or somatic symptom disorders ((S)SD) are common and have a negative impact on the patients' health-related quality of life, healthcare use and costs. In primary care, which is central to the management of (S)SD, diagnosis and treatment tend to be delayed. There is a significant lack of evidence regarding the barriers in the diagnostic process of (S)SD in primary care and how interventions should be tailored to address them. The aim of this study is to analyse the diagnostic process in primary care that results in the diagnosis or non-diagnosis of a (S)SD.

METHODS AND ANALYSIS

This mixed methods study will investigate the topic with qualitative methods, subsequently proceeding to a quantitative phase where the initial results will be validated and/or generalised. First, focus groups will explore meanings and patterns, inconsistencies and conflicts in general practitioners' (GPs) thoughts and behaviours when diagnosing (S)SD. Second, the results of these focus groups will be used to develop interview guidelines for subsequent face-to-face interviews. Patients and their treating GPs will be interviewed separately on how they experience the history of illness, the diagnostic process and treatment. Third, based on the results of the first two study parts, a questionnaire will be derived and a nationwide survey among German GPs will be conducted, quantifying the barriers and difficulties identified before.

ETHICS AND DISSEMINATION

Ethics approval was obtained from the Ethics Committee of the Hamburg Medical Association, Germany (approval number PV4763). The results of this study will be disseminated through conference presentation and publications in peer-reviewed journals.

TRIAL REGISTRATION NUMBER

The study is registered in the German Clinical Trial Register (DRKS), DRKS-ID DRKS00009736.

Bridging a clinical gap in psychogenic nonepileptic seizures: Mental health provider preferences of biopsychosocial assessment approaches

Management of psychogenic nonepileptic seizures (PNES) is complex, requiring multidisciplinary care. A standardized assessment and formulation approach to PNES is lacking, yet use of a comprehensive model may alleviate problems such as mental health aftercare noncompliance. Although a biopsychosocial (BPS) approach to PNES balancing predisposing, precipitating, and perpetuating (PPP) variables has been described and has been recently tested in pilot form, it is unclear how this assessment style is perceived among community mental health practitioners such as psychotherapists (including psychologists, counselors, and social workers). We predicted preference of a comprehensive "BPS/PPP" assessment style by those most involved in PNES care (i.e., community psychotherapists). One hundred and forty-three community-based social workers and counselors completed a survey featuring a fictional PNES case followed by assessment style options ("Multiaxial," "Narrative," and "BPS/PPP"). Respondents clearly preferred the robust BPS/PPP approach over less-comprehensive multiaxial and narrative assessments (p<0.0001). Reasons for choosing the BPS/PPP by respondents include ease of organization, clear therapeutic goals, and comprehensive nature. This assessment of acceptability of a BPS/PPP approach to PNES assessment among community mental health practitioners may provide a patient-centered mechanism to enhance referrals from the neurological to mental health setting. Implications and future directions are explored.

The challenge of diagnosing non-specific, functional, and somatoform disorders: A systematic review of barriers to diagnosis in primary care

OBJECTIVE

Despite their prevalence and impact on patients and the health care system, non-specific, functional, and somatoform disorders are underdiagnosed. This problem is especially problematic in primary care if we are moving towards an integrated care model. The objective of the current study was to identify and aggregate potential barriers to the diagnosis in primary care settings.

METHODS

Our systematic review methodology followed a pre-published protocol and was registered in PROSPERO (CRD42013002540). We combined qualitative and quantitative data from studies identified in online databases and by hand searching of reference lists. Data were synthesized in a data-driven way using a grounded-theory approach. The level of evidence and assessment of bias for the final included studies was independently conducted.

RESULTS

Data from n=177 full text publications were independently extracted and combined in a custom database. The final list of included studies was n=42. From these, a total of n=379 barriers were identified comprising 77 barrier-level codes, 16 thematic categories and five over-arching themes, i.e., patient-related, primary-care-practitioner related, doctor-patient interactional, situational, and conceptual and operational barriers.

CONCLUSION

Given the thematic range of the identified barriers, the diagnostic process of non-specific, functional, and somatoform disorders in primary care is highly complex. Individual or practice-level interventions, as well as public awareness initiatives are needed to help address the diagnostic challenges. A multi-factorial understanding of symptoms with a biopsychosocial parallel diagnostic approach should be encouraged. More direct empirical investigations are also needed.

Collaborative stepped care for somatoform disorders: A pre-post-intervention study in primary care

OBJECTIVE

The successful management of somatoform disorders in primary care is often limited due to low diagnostic accuracy, delayed referral to psychotherapy, and unstructured overuse of health care. This study aimed to investigate the feasibility of establishing a collaborative stepped health care network for somatoform disorders, and its impact on the diagnostic process and treatment recommendations in primary care.

METHOD

The Network for Somatoform and Functional Disorders (Sofu-Net) was established to connect 41 primary care physicians (PCP), 35 psychotherapists, and 8 mental health clinics. To evaluate Sofu-Net, primary care patients at high risk of having a somatoform disorder were identified using the Patient Health Questionnaire, and were assessed in detail at the patient and PCP level. Discussion of psychosocial distress in the consultations, diagnostic detection rates and treatment recommendations were compared before and 12 months after establishing the network.

RESULTS

Out of the pre- (n=1645) and 12-months-post Sofu-Net patient samples (n=1756), 267 (16.2%) and 269 (15.3%) high-risk patients were identified. From these, 156 and 123 patients were interviewed and information was assessed from their PCP. Twelve months after Sofu-Net establishment, high-risk patients more frequently discussed psychosocial distress with their PCP (63.3% vs. 79.2%, p<.001). PCPs prescribed more antidepressants (3.8% vs. 25.2%, p<.001) and less benzodiazepines (21.8% vs. 6.5%, p<.001). Sofu-Net did not affect PCP's diagnostic detection rates or recommendation to initiate psychotherapy.

CONCLUSION

The study results indicate feasibility of an interdisciplinary network for somatoform disorders. Collaborative care networks for somatoform disorders have the potential to improve doctor-patient-communication and prescription behavior.

Construct validity and clinical utility of current research criteria of DSM-5 somatic symptom disorder diagnosis in patients with fibromyalgia syndrome

OBJECTIVE

The validity and clinical utility of current research criteria of the DSM 5 category somatic symptom disorder (SSD) needs to be tested outside the setting of psychiatry.

METHODS

Consecutive patients with an established diagnosis of fibromyalgia syndrome (FMS) were evaluated by medical examination, psychiatric interview and self-report questionnaires in an outpatient pain medicine center. The diagnosis of SSD was established using published research criteria. The discriminative concurrent criterion validity of SSD was tested by comparing FMS-patients with and without SSD as to the amount of impairment and of health care seeking. Two clinicians blinded as to the purpose of the study, assessed the medical reports of patients after the evaluation for the determination of the need for psychotherapy based on the German FMS - guideline recommendations (clinical utility).

RESULTS

25.6% of 156 patients met the criteria of SSD. Patients meeting SSD criteria scored significantly higher in a self-report measure of disability. There were no significant differences in the number of patients on sick leave or applying for disability pension and in self-reported doctor visits and physiotherapy in the previous six months. 95.0% of patients with SSD and 71.6% of patients without SSD met the criteria of a current anxiety or depressive disorder as assessed by the psychiatric interview. 80.0% of patients with SSD and 66.7% of patients without SSD received a recommendation for psychotherapy.

CONCLUSIONS

The construct validity and clinical utility of current research criteria of DSM 5 category SSD were limited in German patients with FMS.

Diagnostic assessment and case formulation in psychogenic nonepileptic seizures: A pilot comparison of approaches

Management of psychogenic nonepileptic seizures (PNES) is complex, requiring multidisciplinary care. A standardized assessment approach to PNES is lacking, yet use of a comprehensive model may alleviate problems such as mental health aftercare noncompliance. Although a biopsychosocial (BPS) approach to PNES balancing predisposing, precipitating, and perpetuating (PPP) variables has been described, it is unclear how this formulation style is perceived amongst clinicians. We predicted preference of a comprehensive, "BPS/PPP" assessment style by those most involved in PNES diagnosis and care (i.e., neurologists and psychologists). Sixty epileptologists, psychiatrists, and psychologists completed a survey featuring a fictional PNES case followed by assessment style options ("Multiaxial," "Narrative," and "BPS/PPP"). Epileptologists and psychologists ("nonpsychiatrists") differed from psychiatrists in PNES case formulation choice, with nonpsychiatrists preferring the robust BPS/PPP approach and with psychiatrists opting for less comprehensive Multiaxial and Narrative assessments (p=0.0009). Reasons for choosing the BPS/PPP by nonpsychiatrists included ease of organization, clear therapeutic goals, and comprehensive nature. Alternatively, psychiatrists cited time constraints and familiarity as reasons to prefer briefer Multiaxial or Narrative approaches. This pilot assessment of acceptability of a BPS/PPP approach to PNES case formulation, thus, reveals important gaps in formulation priorities between neurologists and psychiatrists. Implications and future directions are explored.

Predictors of suicide in patients with conversion disorder

OBJECTIVE

Previous studies have shown that the ratio of suicide attempts is between 19.6 and 34.2% in patients with conversion disorder (CD), yet few studies have addressed this issue. The present study compared demographic and clinical variables and predictors of suicide attempts in patients with CD.

METHODS

A total of 100 consecutive patients were recruited and divided into groups according to their history of suicide attempts. Socio-demographic variables such as economic status, age, gender, educational level, marital status, clinical variables such as the presence of psychiatric disorder in family, substance abuse, risky alcohol use, age of onset, subtype of CD, number of hospitalization were recorded. Participants also completed the Childhood Trauma Questionnaire (CTQ-28), Temperament and Character Inventory (TCI), Toronto Alexithymia Scale (TAS-20), Dissociative Experiences Scale (DES), Beck Anxiety Inventory (BAI), and Beck Depression Inventory (BDI).

RESULTS

Suicide attempters had a higher rate of risky alcohol use, more hospitalizations, and higher mean scores on the BAI, BDI, DES/DES-taxon, TAS-total and CTQ-total than did non-suicide attempters or healthy control (NHC). Patients with CD had a higher harm-avoidance and a lower self-directedness rather than NHC. Risky alcohol use, number of hospitalizations, and mean DES-taxon and emotional abuse scores were independent predictors of suicide attempts.

CONCLUSION

Our findings indicate that clinicians should be aware of the prediction of suicide in patients with CD who show dissociation and risky alcohol use. Moreover, a history of childhood emotional abuse should be considered in the management of CD. The fact that clinical variables distinguished between suicide attempters and non-attempters suggests that a history of suicide attempts may be used to clarify the heterogeneous nature of CD.

Barriers to the diagnosis of somatoform disorders in primary care: protocol for a systematic review of the current status

BACKGROUND

Somatoform-type disorders and functional medically unexplained symptoms are extremely common in primary care settings. These disorders, however, are consistently underdiagnosed and under-recognised which precludes effective treatment. Given that somatoform symptoms are associated with high impairment, healthcare costs and both physician and patient frustration, it is critical to improve early detection. The first step in improving patient care is to identify the current barriers which obstruct successful diagnosis to enable the design of targeted interventions. We aim to conduct a systematic review to identify the possible physician-, patient- and society-related factors and other practical constraints which may impede successful diagnosis. In the process, we will also be able to recognise the differences in methodological techniques, recommend potential avenues for future research and comment on the literature in this field as a whole.

METHODS/DESIGN

We aim to conduct a systematic review of the relevant peer-reviewed literature published in English or German in the past 10 years in MEDLINE, EMBASE, PsycINFO and the Cochrane Database of Systematic Reviews. Additional studies may be identified from the reference lists of included studies. Title and abstract screening and data extraction from full text manuscripts will be conducted by two independent reviewers. Because we are including a combination of qualitative and quantitative studies, the review will provide a broad understanding of the current situation. Wherever possible, the method and reporting of the review will adhere to the guidelines outlined in the PRISMA statement and bias will be assessed using the Cochrane collaboration's recommendations. We envisage that data will be synthesised using a multilevel (qualitative and quantitative) approach which combines textual narrative and thematic analysis. Barriers will be categorised as modifiable or non-modifiable according to a conceptual framework. The review has been registered in an international registry of systematic reviews PROSPERO (CRD42013002540).

DISCUSSION

We hope that this study will provide an insight into the barriers to diagnosis of somatoform-type disorders and the results can be used to target appropriate interventions to improve care for these patients.

Somatic symptom disorder: an important change in DSM

This paper describes the rationale for the new diagnosis of somatic symptom disorder (SSD) within DSM5. SSD represents a consolidation of a number of previously listed diagnoses. It deemphasizes the centrality of medically unexplained symptoms and defines the disorder on the basis of persistent somatic symptoms associated with disproportionate thoughts, feelings, and behaviors related to these symptoms. Data are presented concerning reliability, validity, and prevalence of SSD, as well as tasks for future research, education, and clinical practice.

Emerging themes in the revision of the classification of somatoform disorders

The somatoform disorders, as currently defined in DSM-IV and ICD-10, have been criticized for their complexity and poor clinical utility. In this paper we consider these criticisms as well as the conceptual question of whether there is sufficient evidence for classifying them as mental and behavioural disorders. The review suggests that, as currently defined, somatoform disorders do not fulfil a recently articulated set of criteria for mental and behavioural disorders. In particular, the disorders are not defined according to positive psychological and behavioural disorders and evidence is sparse to support their classification as different and distinct diagnoses. Any revision of the disorders should not be based on 'medically unexplained' symptoms. Rather, the relevant diagnoses should include a combination of bothersome somatic symptoms with several other psychological features including beliefs about somatic symptoms and evidence of marked concerns about health and illness. Finally, the review presents a set of proposals for the revision of these disorders, by the Somatic Disorders and Dissociative Disorders Working Group of the WHO International Advisory Group for the Revision of ICD-10 Mental and Behavioural Disorders, which attempt to take account of the criticisms and current understanding of somatic experiences.
