Optimising child and adolescent mental health care – a scoping review of international best-practice strategies and service models

Psychiatric disorders are among the most common health problems in children and adolescents, with a recent prevalence rise due to the COVID-19 pandemic. The increasing demand for service provision in this patient population, together with infrastructural, financial and staff limitations in child and adolescent mental health services, calls for an adaptation/advancement of current models of service provision. This review offers an internationally informed overview of best-practice child and adolescent mental health (CAMH) strategies and care models, with the aim of assisting decision-makers in implementing topical CAMH care models.

Using a pre-defined structured search strategy, we aimed to identify core topics within published CAMH strategies and care model documents from seven countries within the Global North, which represented a range of differing healthcare systems, geographical regions, and public health traditions. From the retrieved documents, we then systematically extracted data in an iterative process, and summarised these narratively by applying qualitative content analyses.

Our search retrieved the following key components of CAMH strategies: awareness-raising activities, prevention/promotion, detection, treatment, telemedicine, care pathways, transitional psychiatry, vulnerable patient groups, user participation, infrastructure, workforce development, implementation, digital case management tools, and data acquisition/research. Recommendations for CAMH care organisation often followed a public mental health approach, with a focus on mental health promotion, cross-sectional organisation, and funding of CAMH care services. As key principles of best-practice CAMH care models, we identified increased flexibility of care settings, early intervention, and a strengths-oriented approach, with overarching mental health services research alongside.

In order to design robust models of CAMH care and to mitigate current shortcomings, actions on the policy level (e.g., CAMH strategy development with a focus on mental health promotion, installation of cross-sectoral governance), at the organisational level (e.g., re-organisation of treatment settings and pathways of care) and at the individual level (e.g., user involvement, workforce development) are recommended. To this purpose, we strongly advocate the use of cross-sectoral and participatory approaches for CAMH care structures with accompanying health services research.
