The mesosystem of mental health services and support: Mapping its actors, their collaborations, and client mental health outcomes and experiences.

This review aims to map the mesosystem for treatment and support for persons with mental illnesses.

To synthesize qualitative, quantitative and mixed methods findings, it utilizes a systematic integrative methodology.Specific questions include:Who are the actors in this mesosystem?How are collaborations among actors organized and implemented?

How do mesosystem activities incorporate (1) coproduction, (2) interprofessional work, (3) recovery principles and (4) community involvement, and how can this inform future redesign?What are mental health outcomes and experiences of patients?Due to changing demographics, the welfare system needs revision and optimization.

Scientific advances and better lifestyle habits contribute to increased life expectancy.

People live longer with illnesses, and the total share of the population with illnesses, including mental illnesses, increase. Concurrently, both financial resources and availability of staff decrease. On an organizational level, innovative solutions are necessary. In improvement work, a first step is to characterize the existing environment.

This project aims to provide a platform for potential future improvement.Frequently, psychiatric conditions require long-term maintenance. Reports point to that Swedish persons with mental illness and comorbid conditions fail to get their needs met. Integrated treatment has superior effectiveness. Still, coordinated support is rarely available.

Mesosystem, fragmentation renders individual suffering and inefficient use of societal resources.

There is need for improved collaboration and integration.Unfortunately, the recently widely used Swedish term "nära vård" (close care) does not make references to social and welfare services (beyond health) and society at large.

At these interfaces, (1) coproduction, (2) interprofessional work, (3) recovery principles and (4) community involvement are likely important drivers. To our knowledge, these four themes have not yet been brought together.
