This paper is concerned with the care of the most difficult and severe
ly disabled new patients presenting to mental health services in the U
.K. Questions of definition will be examined and the clinical and soci
al characteristics of the population discussed. Since the defining cha
racteristics (and prevalence) of this group are strongly affected by t
he overall service context, the range of community provisions within o
ne health district (Cambridge) will be described. Examples of a new ki
nd of institutional solution-the 'ward-in-a-house'-will then be presen
ted, together with the underlying principles of management and care. T
he benefits and limitations of the model will be discussed.
