To date, there has been no survey concerning psychiatric isolation roo
ms in France. We conducted a mail survey in 1993 involving all adult p
sychiatric care catchment areas covering the French departments. The s
urvey revealed an estimated number of 1560 isolation rooms. Isolation
rooms were considered as absolutely necessary in all the departments b
ut also as an unsatisfactory solution by one-third of them. Isolation
rooms were usually small and poorly adapted to efficient patient surve
illance. Furthermore, equipment was often inadequate, particularly for
noise and fire protection. A serious accident (fire, suicide, escape)
was reported by large number of departments. The rooms were used for
agitated psychotic (84%) and psychopathic (16) people. Although reques
ted by the physician, bur also in some cases by the patient, condition
s of use and design of isolation rooms may be dangerous both for the p
atient and the nursing staff Financial investment devoted to isolation
rooms varies greatly and there is no specific control over the number
of installation. Construction must comply with precise specifications
defined in co-ordination with the experts involved.
