The objective of this study is to estimate the proportion of the popul
ation in The Netherlands who receive long-term care for chronic psychi
atric problems. The care needs of this population are assessed in term
s both of diagnosis and of specific impairments and disabilities. Data
from three surveys and two psychiatric case registers in five differe
nt areas of The Netherlands provide an estimate of about 3.5 long-term
users of psychiatric care per 1000 members of the population aged 20
years or over. One-third of them receive a diagnosis of schizophrenia
and related psychotic disorders. Patients most frequently suffer from
impairments of mood and affect, volition and drives. Nearly all patien
ts are disabled in their occupational role (work), and about half of t
he population have problems with self-care and household tasks. Long-t
erm care is to a large extent (40%) provided in hospitals and sheltere
d accommodation, and the role of day services is relatively insignific
ant.
