The objective of the study was to collected data about the changes in a welfare society about the new institutional landscape after the mental hospital area. Data about interventions from social welfare agencies, psychiatric care, and prisons were collected from local and national register as well as data about cause of death and socio-economic status for 1355 persons treated with a diagnosis of psychosis in a Stockholm area 2004–2008. Psychiatric in-patient care and prisons are marginalized. Different interventions in open care touched a very large number of persons. Social welfare agencies play an increasing role in this context.
