Definition of deinstitutionalization ?Deinstitutionalization is a long-term trend wherein fewer people reside as patients in mental hospitals and fewer mental health treatments are delivered in public hospitals. This trend is directly due to the process of closing public hospitals and the ensuing transfers of patients to community-based mental health services in the late twentieth century. It represents the dissipation of patients over a wider variety of health care settings and geographic areas. Deinstitutionalization also illustrates evolution in the structure, practice, experiences, and purposes of mental health care in the United States.
