Patients with affective disorders admitted to maximum secure care (1999--2003).

The State Hospital, Carstairs, is a special secure psychiatric facility for Scotland and Northern Ireland. This study describes the background, illness and offence (where appropriate) characteristics of 25 patients admitted between 1999 and 2003 with a diagnosis of any affective disorder. Patients were, on average, 37 years old and had a lengthy history of psychiatric contact. Patients with an affective disorder were more likely to be admitted under civil proceedings, following a transfer from hospital, as opposed to being admitted under criminal procedure. Sixty per cent were discharged to prison, court or local hospitals within one year of their admission to special secure care. Significant violence during an episode of mania or hypomania (even in the presence of psychotic symptoms) appears rare. Recurrent unipolar depression resistant to first and second line treatments in women, and lithium withdrawal mania in male bipolar patients were the most common clinical problems. Treatments aimed at reducing co-morbid substance misuse, and improving compliance with mood stabilisers, appear important in managing this patient group.
