The Cassel Hospital, London.

This paper is an account of the principles and practices of treatment offered at the Cassel Hospital, London, with a particular focus on the Inpatient Families Unit. The Cassel Hospital is an internationally renowned therapeutic community, the operation of which is based on psychoanalytic principles and which has operated within the British National Health Service for nearly 50 years. An account of the historical development of the hospital is given as well as a description of its structure and function. The following three innovative structures are elaborated: a complex network within which patients can develop, Cassel-style nursing care, and nurse-therapist supervision. Theoretical underpinnings are outlined, which together with two case studies facilitate an appreciation of the capacity of the therapeutic network to foster the successful treatment of a range of severely disordered individuals and families. Such treatment may approach a level perhaps otherwise unattainable and which is widely applicable in the public hospital and clinic settings in Australia.
