The number of beds available in the UK for the treatment of mental illness has fallen by over two-thirds since its peak in the mid-1950s. There is a worldwide trend of closure of large mental hospitals and integration of services for the mentally ill in their own local community. Community surveys have shown that an overwhelming majority of mentally ill people are treated in primary care or by specialists, but without being admitted to a hospital. This is now the preferred clinical practice (Shepherd et al, 1981).
