Viewing Psychiatric Epidemiology Within a Global Historical Framework to Shape Future Practice.

This Viewpoint discusses the benefits of rethinking the history of psychiatric epidemiology from a global perspective.

Case-controlled field study of the ICD-11 clinical descriptions and diagnostic requirements for Bodily Distress Disorders.

AIMS: Mental disorders characterized by preoccupation with distressing bodily symptoms and associated functional impairment have been a target of major reconceptualization in the ICD-11, in which a single category of Bodily Distress Disorder (BDD) with different levels of severity replaces most of the Somatoform Disorders in ICD-10. This study compared the accuracy of clinicians' diagnosis of disorders of somatic symptoms using either the ICD-11 or ICD-10 diagnostic guidelines in an online study. METHODS: Clinically active members of the World Health Organization's Global Clinical Practice Network (N = 1065) participating in English, Spanish, or Japanese were randomly assigned to apply ICD-11 or ICD-10 diagnostic guidelines to one of nine pairs of standardized case vignettes. The accuracy of the clinicians' diagnoses as well as their ratings of the guidelines' clinical utility were assessed. RESULTS: Overall, clinicians were more accurate using ICD-11 compared to ICD-10 for every presentation of a vignette characterized primarily by bodily symptoms associated with distress and impairment. Clinicians who made a diagnosis of BDD using ICD-11 were generally correct in applying the severity specifiers for the condition. LIMITATIONS: This sample may represent some self-selection bias and thus may not generalize to all clinicians. Additionally, diagnostic decisions with live patients may lead to different results. CONCLUSIONS: The ICD-11 diagnostic guidelines for BDD represent an improvement over those for Somatoform Disorders in ICD-10 in regard to clinicians' diagnostic accuracy and perceived clinical utility.

The social underpinnings of mental distress in the time of COVID-19 - time for urgent action.

We argue that predictions of a 'tsunami' of mental health problems as a consequence of the pandemic of coronavirus disease 2019 (COVID-19) and the lockdown are overstated; feelings of anxiety and sadness are entirely normal reactions to difficult circumstances, not symptoms of poor mental health.  Some people will need specialised mental health support, especially those already leading tough lives; we need immediate reversal of years of underfunding of community mental health services.  However, the disproportionate effects of COVID-19 on the most disadvantaged, especially BAME people placed at risk by their social and economic conditions, were entirely predictable. Mental health is best ensured by urgently rebuilding the social and economic supports stripped away over the last decade. Governments must pump funds into local authorities to rebuild community services, peer support, mutual aid and local community and voluntary sector organisations.  Health care organisations must tackle racism and discrimination to ensure genuine equal access to universal health care.  Government must replace highly conditional benefit systems by something like a universal basic income. All economic and social policies must be subjected to a legally binding mental health audit. This may sound unfeasibly expensive, but the social and economic costs, not to mention the costs in personal and community suffering, though often invisible, are far greater.

Crisis Response as a Human Rights Flashpoint: Critical Elements of Community Support for Individuals Experiencing Significant Emotional Distress.

This paper proposes a set of nine critical elements underpinned by human rights principles to support individuals experiencing a serious crisis related to mental health problems or psychosocial disabilities. These elements are distilled from a range of viable alternatives to traditional community mental health approaches and are linked to a normative human rights framework. We argue that crisis response is one of the areas of mental health care where there is a heightened risk that the rights of service recipients may be infringed. We further make the case that the nine critical elements found in advanced mental health care models should be used as building blocks for designing services and systems that promote effective rights-based care and supports.

Genealogies and Anthropologies of Global Mental Health.

Within the proliferation of studies identified with global mental health, anthropologists rarely take global mental health itself as their object of inquiry. The papers in this special issue were selected specifically to problematize global mental health. To contextualize them, this introduction critically weighs three possible genealogies through which the emergence of global health can be explored: (1) as a divergent thread in the qualitative turn of global health away from earlier international health and development; (2) as the product of networks and social movements; and (3) as a diagnostically- and metrics-driven psychiatric imperialism, reinforced by pharmaceutical markets. Each paper tackles a different component of the assemblage of global mental health: knowledge production and circulation, global mental health principles enacted in situ, and subaltern modalities of healing through which global mental health can be questioned. Pluralizing anthropology, the articles include research sites in meeting rooms, universities, research laboratories, clinics, healers and health screening camps, households, and the public spaces of everyday life, in India, Ghana, Brazil, Senegal, South Africa, Kosovo and Palestine, as well as in US and European institutions that constitute nodes in the global network through which scientific knowledge and certain models of mental health circulate.

Falling, Dying Sheep, and the Divine: Notes on Thick Therapeutics in Peri-Urban Senegal.

Peri-urban Senegal lies outside the influence of both the nation's historic public mental health model and contemporary global mental health. This paper examines how cultural logics in this underserved region spill over from social domains to widen the therapeutic sphere of psychoses and epilepsy. Observations and 60 carer and/or patient interviews concerning 36 patients afflicted by one or both conditions illustrate how the "crisis of the uncanny", a spectacular eruption of psychoses and seizures into the everyday, triggers trajectories across these domains. To resolve the crisis, patients and carers mobilize debts and obligations of extended kin and community, as well as a gift economy among strangers. The therapeutic and non-therapeutic are further linked through the semantics of falling, which associates this local term for the crisis with divine ecstasy and the slide from human to non-human forms of life. We introduce the concept of thick therapeutics to capture how the logics of sheep- other animal-human relationality, secular-divine politics of giving, and payment/sacrifice for healing imbue a therapeutic assemblage continually constructed through actions of patients, carers and healers. We ask what implications therapeutic thickening might have for mental health futures, such as monetized payment under global mental health.

Innovations and changes in the ICD-11 classification of mental, behavioural and neurodevelopmental disorders.

Following approval of the ICD-11 by the World Health Assembly in May 2019, World Health Organization (WHO) member states will transition from the ICD-10 to the ICD-11, with reporting of health statistics based on the new system to begin on January 1, 2022. The WHO Department of Mental Health and Substance Abuse will publish Clinical Descriptions and Diagnostic Guidelines (CDDG) for ICD-11 Mental, Behavioural and Neurodevelopmental Disorders following ICD-11's approval. The development of the ICD-11 CDDG over the past decade, based on the principles of clinical utility and global applicability, has been the most broadly international, multilingual, multidisciplinary and participative revision process ever implemented for a classification of mental disorders. Innovations in the ICD-11 include the provision of consistent and systematically characterized information, the adoption of a lifespan approach, and culture-related guidance for each disorder. Dimensional approaches have been incorporated into the classification, particularly for personality disorders and primary psychotic disorders, in ways that are consistent with current evidence, are more compatible with recovery-based approaches, eliminate artificial comorbidity, and more effectively capture changes over time. Here we describe major changes to the structure of the ICD-11 classification of mental disorders as compared to the ICD-10, and the development of two new ICD-11 chapters relevant to mental health practice. We illustrate a set of new categories that have been added to the ICD-11 and present the rationale for their inclusion. Finally, we provide a description of the important changes that have been made in each ICD-11 disorder grouping. This information is intended to be useful for both clinicians and researchers in orienting themselves to the ICD-11 and in preparing for implementation in their own professional contexts.

Clinical utility of ICD-11 diagnostic guidelines for high-burden mental disorders: results from mental health settings in 13 countries.

In this paper we report the clinical utility of the diagnostic guidelines for ICD-11 mental, behavioural and neurodevelopmental disorders as assessed by 339 clinicians in 1,806 patients in 28 mental health settings in 13 countries. Clinician raters applied the guidelines for schizophrenia and other primary psychotic disorders, mood disorders (depressive and bipolar disorders), anxiety and fear-related disorders, and disorders specifically associated with stress. Clinician ratings of the clinical utility of the proposed ICD-11 diagnostic guidelines were very positive overall. The guidelines were perceived as easy to use, corresponding accurately to patients' presentations (i.e., goodness of fit), clear and understandable, providing an appropriate level of detail, taking about the same or less time than clinicians' usual practice, and providing useful guidance about distinguishing disorder from normality and from other disorders. Clinicians evaluated the guidelines as less useful for treatment selection and assessing prognosis than for communicating with other health professionals, though the former ratings were still positive overall. Field studies that assess perceived clinical utility of the proposed ICD-11 diagnostic guidelines among their intended users have very important implications. Classification is the interface between health encounters and health information; if clinicians do not find that a new diagnostic system provides clinically useful information, they are unlikely to apply it consistently and faithfully. This would have a major impact on the validity of aggregated health encounter data used for health policy and decision making. Overall, the results of this study provide considerable reason to be optimistic about the perceived clinical utility of the ICD-11 among global clinicians.

The ICD-11 developmental field study of reliability of diagnoses of high-burden mental disorders: results among adult patients in mental health settings of 13 countries.

Reliable, clinically useful, and globally applicable diagnostic classification of mental disorders is an essential foundation for global mental health. The World Health Organization (WHO) is nearing completion of the 11th revision of the International Classification of Diseases and Related Health Problems (ICD-11). The present study assessed inter-diagnostician reliability of mental disorders accounting for the greatest proportion of global disease burden and the highest levels of service utilization - schizophrenia and other primary psychotic disorders, mood disorders, anxiety and fear-related disorders, and disorders specifically associated with stress - among adult patients presenting for treatment at 28 participating centers in 13 countries. A concurrent joint-rater design was used, focusing specifically on whether two clinicians, relying on the same clinical information, agreed on the diagnosis when separately applying the ICD-11 diagnostic guidelines. A total of 1,806 patients were assessed by 339 clinicians in the local language. Intraclass kappa coefficients for diagnoses weighted by site and study prevalence ranged from 0.45 (dysthymic disorder) to 0.88 (social anxiety disorder) and would be considered moderate to almost perfect for all diagnoses. Overall, the reliability of the ICD-11 diagnostic guidelines was superior to that previously reported for equivalent ICD-10 guidelines. These data provide support for the suitability of the ICD-11 diagnostic guidelines for implementation at a global level. The findings will inform further revision of the ICD-11 diagnostic guidelines prior to their publication and the development of programs to support professional training and implementation of the ICD-11 by WHO member states.

Disorders specifically associated with stress: A case-controlled field study for ICD-11 mental and behavioural disorders / Trastornos específicamente relacionados con el estrés: estudio de campo de casos controlados para la CIE-11

As part of the development of the Eleventh Revision of International Classification of Diseases and Related Health Problems (ICD-11), the World Health Organization Department of Mental Health and Substance Abuse is conducting a series of case-controlled field studies using a new and powerful method to test the application by clinicians of the proposed ICD-11 diagnostic guidelines for mental and behavioural disorders. This article describes the case-controlled field study for Disorders Specifically Associated with Stress. Using a vignette-based experimental methodology, 1,738 international mental health professionals diagnosed standardized cases designed to test key differences between the proposed diagnostic guidelines for ICD-11 and corresponding guidelines for ICD-10. Across eight comparisons, several proposed changes for ICD-11, including the addition of Complex PTSD and Prolonged Grief Disorder, produced significantly improved diagnostic decisions and clearer application of diagnostic guidelines compared to ICD-10. However, several key areas were also identified, such as the description of the diagnostic requirement of re-experiencing in PTSD, in which the guidelines were not consistently applied as intended. These results informed specific revisions to improve the clarity of the proposed ICD-11 diagnostic guidelines. The next step will be to further test these guidelines in clinic-based studies using real patients in relevant settings (AU)

Como parte del desarrollo de la onceava versión de la Clasificación Internacional de Enfermedades y Problemas de Salud Relacionados (CIE-11), la Organización Mundial de la Salud está conduciendo una serie de estudios de campo de casos controlados utilizando un novedoso y potente método para evaluar la aplicación por parte de clínicos de las guías diagnósticas para los trastornos mentales y del comportamiento. Este artículo describe el estudio de campo de casos controlados para los Trastornos específicamente relacionados con el estrés. Con base en una metodología experimental de viñetas, 1.738 profesionales de la salud mental diagnosticaron casos estandarizados específicamente diseñados para evaluar diferencias clave entre las guías propuestas para la CIE-11 y las que les corresponden en la CIE-10. Diversos cambios propuestos para la CIE-11, incluyendo la adición del TEPT complejo y del Trastorno por duelo prolongado, produjeron mejores decisiones diagnósticas en comparación con la versión previa del manual. Sin embargo, se identificaron también áreas en las que las guías no se aplicaron de manera consistente, como el requisito diagnóstico de re-experimentación para el TEPT, lo que informó revisiones específicas para mejorar las guías diagnósticas, que serán evaluadas en futuros estudios basados en la clínica con pacientes reales en escenarios relevante (AU)

The Use of Magnetic Resonance Imaging Screening for Optic Pathway Gliomas in Children with Neurofibromatosis Type 1.

OBJECTIVE: To evaluate the utility of screening brain/orbital magnetic resonance imaging (MRI) in a large population of children with neurofibromatosis type 1 (NF1) over a 20-year period. STUDY DESIGN: A retrospective analysis of clinical and imaging data from children with NF1 seen at a single center between 1990 and 2010 was performed. RESULTS: During the 20-year study period, 826 individuals with NF1 (402 females, 424 males) ages 1-9 years were screened for optic pathway gliomas (OPGs) using brain/orbital MRI; 18% were identified with OPGs with a median age at detection of 3 years. Fifteen percent of patients with OPGs had radiologic or clinical progression requiring therapy. Children with chiasmatic and postchiasmatic tumors were more likely to require therapy compared with patients with prechiasmatic OPGs (P < .0001). Patients with visual deficits at the time of diagnosis were more likely to experience visual decline despite therapy when compared with patients treated based on radiologic progression (P < .012). CONCLUSIONS: Our findings confirm that chiasmatic and postchiasmatic OPG in children with NF1 have the highest risk for progression and vision loss. Early identification of OPG by screening MRI prior to the development of vision loss may lead to improved visual outcomes. Children with negative brain and orbital MRI screening at age 15 months or later did not develop symptomatic OPGs.

The World Health Organization and the contested beginnings of psychiatric epidemiology as an international discipline: one rope, many strands.

This paper focuses on the relatively late emergence of psychiatric epidemiology as an international discipline, through local-global exchanges during the first 15 years of the World Health Organization (WHO). Building an epidemiological canon within WHO's Mental Health Programme faced numerous obstacles. First, an idealist notion of mental health inherent in WHO's own definition of health contributed to tensions around the object of psychiatric epidemiology. Second, the transfer of methods from medical epidemiology to research on mental disorders required mobilizing conceptual justifications, including a 'contagion argument'. Third, epidemiological research at WHO was stymied by other public health needs, resource scarcity and cultural barriers. This history partly recapitulates the development of psychiatric epidemiology in North America and Europe, but is also shaped by concerns in the developing world, translated through first-world 'experts'. Resolving the tensions arising from these obstacles allowed WHO to establish its international schizophrenia research, which in turn provided proof of concept for psychiatric epidemiology in the place of scepticism within and without psychiatry.

The history of the development of buprenorphine as an addiction therapeutic.

This paper traces the early 21st century success of the agonist-antagonist buprenorphine and the combination drug buprenorphine with naloxone within the broader quest to develop addiction therapeutics that began in the 1920s as the search for a nonaddictive analgesic. Drawing on archival research, document analysis, and interviews with contemporary actors, this paper situates the social organization of laboratory-based and clinical research within the domestic and international confluence of several issues, including research ethics, drug regulation, public attitudes, tensions around definitions of drug addiction, and the evolving roles of the pharmaceutical industry. The fervor that drove the champions of buprenorphine must be understood in relation to (1) the material work of research and pharmaceutical manufacturing; (2) the symbolic role of buprenorphine as a solution to numerous problems with addiction treatment evident by the mid-1970s; the destigmatization and individualization of addicts as patients; and (3) the complex configurations of public and private partnerships.

Pediatric plexiform neurofibromas: impact on morbidity and mortality in neurofibromatosis type 1.

OBJECTIVE: To characterize morbidity, mortality, and surgical outcomes in pediatric patients with symptomatic plexiform neurofibromas (PNFs). STUDY DESIGN: We conducted retrospective analysis of data from clinical records of surgical history and other neurofibromatosis type 1 (NF1)-related complications in children with PNFs seen at Cincinnati Children's Hospital Medical Center between 1997 and 2007. RESULTS: A total of 154 children with NF1 and PNFs were identified. Children with symptomatic PNFs had increased incidence of other NF1-related tumors (P < .05). Patients with NF1 and PNFs had a higher mortality rate (5/154, 3.2%) when compared with patients without or with asymptomatic PNFs (2/366, 0.5%; P = .024). The most common morbidities leading to surgeries were neurologic, disfigurement, orthopedic, and airway complaints. Less extensive resection predicted a shorter interval to second surgery (P < .0019). The highest recurrence was seen in tumors located in the head, neck, and thorax (P < .001). CONCLUSIONS: These findings quantify the increased risk for additional tumors and mortality associated with symptomatic PNFs. Surgical interventions were required in many cases and resulted in added morbidity in some cases. Patients with PNFs were more likely to benefit from surgery when the indications were airway compression or disfigurement.

Debating life after disaster: charity hospital babies and bioscientific futures in post-Katrina New Orleans.

In Louisiana's unique, populist-derived charity health system, the self-designation Charity Hospital Baby expresses situational identity anchored in the life cycle and the inversion of racist and authoritative connotations. This article draws on theoretical perspectives of stratified reproduction and the politics of time to examine the controversy in which Babies advocate reopening the Katrina-damaged New Orleans Charity Hospital, and administrators and planners support a new state-of-the-art biosciences district, GNOBED. Babies evoke the present, ethical urgency (kairos) of responding to sickness and disability; GNOBED implies prolonging or saving future lives through biotechnologies under development in accelerated time (chronos). As preservationists and residents threatened with displacement join "re-open Charity" proponents, planners symbolically engage in prolepsis, rhetorically precluding opposing arguments with flash forward of supposedly "done deals." At stake is nothing less than social death for a segment of this ethnically diverse city. [public
