Child and adolescent psychiatric genetics

The current status of child and adolescent psychiatric genetics appears promising in light of the initiation of genome-wide association studies (GWAS) for diverse polygenic disorders and the molecular elucidation of monogenic Rett syndrome, for which recent functional studies provide hope for pharmacological treatment strategies. Within the last 50 years, tremendous progress has been made in linking genetic variation to behavioral phenotypes and psychiatric disorders. We summarize the major findings of the Human Genome Project and dwell on largely unsuccessful candidate gene and linkage studies. GWAS for the first time offer the possibility to detect single nucleotide polymorphisms and copy number variants without a priori hypotheses as to their molecular etiology. At the same time it is becoming increasingly clear that very large sample sizes are required in order to enable genome wide significant findings, thus necessitating further large-scaled ascertainment schemes for the successful elucidation of the molecular genetics of childhood and adolescent psychiatric disorders. We conclude by reflecting on different scenarios for future research into the molecular basis of early onset psychiatric disorders. This review represents the introductory article of this special issue of the European Child and Adolescent Psychiatry.

A critical analysis of Child and Adolescent Mental Health Services policy in England, 2000‐2015

Policy in Child and Adolescent Mental Health (CAMH) in England has undergone radical changes in the last 15 years, with far reaching implications for funding models, access to services and service delivery. Using corpus analysis and critical discourse analysis, we explore how childhood, mental health, and CAMHS are constituted in 15 policy documents, 9 pre‐2010, and 6 post 2010. We trace how these constructions have changed over time, and consider the practice implications of these changes. We identify how children’s distress is individualised, through medicalising discourses and shifting understandings of the relationship between socioeconomic context and mental health. This is evidenced in a shift from seeing children’s mental health challenges as produced by social and economic inequities, to a view that children’s mental health must be addressed early to prevent future socio‐economic burden. We consider the implications CAMHS policies for the relationship between children, families, mental health services and the state. The paper concludes by exploring how concepts of ‘parity of esteem’ and ‘stigma reduction’ may inadvertently exacerbate the individualisation of children’s mental health.

Early Detection and Treatment of Psychosis: The Bern Child and Adolescent Psychiatric Perspective

Commonly conceptualized as neurodevelopmental disorders of yet poorly understood aetiology, schizophrenia and other nonorganic psychoses remain one of the most debilitating illnesses with often poor outcome despite all progress in treatment of the manifest disorder. Drawing on the frequent poor outcome of psychosis and its association with the frequently extended periods of untreated first-episode psychosis (FEP) including its prodrome, an early detection and treatment of both the FEP and the preceding at-risk mental state (ARMS) have been increasingly studied. Thereby both approaches are confronted with different problems, for example, treatment engagement in FEP and predictive accuracy in ARMS. They share, however, the problems related to the lack of understanding of developmental, that is, age-related, peculiarities and of the presentation and natural course of their cardinal symptoms in the community. Most research on early detection and intervention in FEP and ARMS is still related to clinical psychiatric samples, and little is known about symptom presentation and burden and help-seeking in the general population related to these experiences. Furthermore, in particular in the early detection of an ARMS, studies often address adolescents and young adults alike without consideration of developmental characteristics, thereby applying risk criteria that have been developed predominately in adults. Combining our earlier experiences described in this paper in child and adolescent, and general psychiatry as well as in both lines of research, that is, on early psychosis and its treatment and on the early detection of psychosis, in particular in its very early states by subjective disturbances in terms of basic symptoms, age-related developmental and epidemiological aspects have therefore been made the focus of our current studies in Bern, thus making our line of research unique

The use of email in a child and adolescent mental health service: are staff ready?

All staff members of a child and adolescent mental health service were invited to participate in a survey about the use of email. Sixty-two of the 105 staff members responded to the survey, a participation rate of 59%. Of the respondents, 32 were allied health staff, 10 were nurses, seven were administrative staff, six were medical staff, three were operational staff and four were acting in a combination of these roles. The respondents reported extensive work-related email usage and considered that they were confident in using email despite low levels of training. However, they did not feel that they understood the legal and ethical issues involved. Furthermore, there was limited incorporation of email into standard record keeping. The majority of respondents thought that increased use of email would lead to a greater workload, a consequence they considered would probably increase over time. Many commented on the quick and practical use of this medium, but were wary about using email with individuals outside the service organization, especially if it were to contain clinical material. There was low use of email directly with clients, and clinicians were ambivalent about incorporating email into therapy. The results suggest that it is timely to consider the utility and appropriateness of email communication with clients and external service providers, and to formulate guidelines and procedures to ensure the confidentiality of client information and the safety of clients and staff.

PRN Sedation-patterns of prescribing and administration in a child and adolescent mental health inpatient service

Objective: To identify utilisation rates of prn (pro re nata) sedation in children and adolescents receiving inpatient psychiatric treatment, and to compare correlates of prn prescribing and administration. Method A retrospective chart review examined 122 medical charts from a child and youth mental health inpatient service. Results 71.3% of patients were prescribed prn sedation and 50.8% were administered prn sedation. Patients received an average of 8.0 doses of prn sedation, with 9.8% receiving 10 or more doses. Chlorpromazine and diazepam were the most commonly utilised agents. Prescribing of prn sedation was only related to use of regular medications (p < 0.01), and non-parent carers (p < 0.01). In contrast, administration of prn sedation was associated with multiple diagnoses (p < 0.01), pervasive development disorder (p < 0.01), mental retardation (p < 0.01) ADHD (p < 0.01), longer hospital admission (p < 0.01), use of atypical antipsychotics (p < 0.01) and polypharmacy (p < 0.01). Conclusions Despite lack of data to inform practice, prn sedation is widely utilised, especially in complex patients. Future research in this area needs to incorporate nurses and examine whether patients benefit from prn sedation, which drugs and dosing patterns optimise safety and efficacy, and what is the role of prn sedation in the context of other medication.

Psychotropic medication utilization in a child and adolescent mental health service

Objectives: This study aimed to identify rates and correlates of psychotropic drug utilization in children and adolescents in inpatient and outpatient settings. Methods: A retrospective chart review examined 122 inpatient and 126 outpatient charts from a metropolitan child and youth mental health service in Brisbane, Australia. Results: Inpatients received more psychotropic medication than outpatients (71% vs. 25%; p < 0.01). Patients receiving medication were older, had longer hospital admissions, and more complex presentations, including history of abuse or suicide attempts and more diagnoses (all p < 0.01). Selective serotonin reuptake inhibitors (SSRIs) were the most frequently used drug class (44% inpatients; 14% outpatients), primarily indicated for mood disorders (31%). SSRIs and newer antidepressants (ADs) were used more frequently in patients with a high suicide risk (p < 0.01). Atypical antipsychotics (APs) were also used (inpatients 23%; outpatients 3%), primarily for behavioral disturbances. Half of those receiving medication (51%) received polypharmacy (> 1 concurrent drug), with up to four drugs used at one time. Rates of polypharmacy were highest among patients receiving antipsychotics. Conclusions: Use of psychotropic medication is frequent in this population. Future research should initially focus on inpatients and intensive treatment settings and examine both safety and efficacy of interventions for depression in young people, atypical antipsychotics for behavioral disturbances, and polypharmacy.
