This chapter aims to guide practitioners and managers in setting up and reviewing community outreach services for people with severe mental illness from a non-technical service planning perspective. Examples of different service configurations within a comprehensive local system are given, with some observations on their relative merits and drawbacks from evaluations. Service models and structures are important for providing a framework for delivering quality care, yet from the perspective of the service user, many of these service details—integrated care, specialization, caseload size, staffing mix, ownership of beds, and degree of shared caseload—are invisible. For people with severe mental health problems, patients and carers value the principles of good community-based care, such as access, responsiveness, consistency, and continuity.
