The authors try to define the notion of psychiatric emergency << patho
logy covering a whole line of situations characterized by their partic
ularly acute and dramatic behaviors, their constant dealing with human
relations, the high frequency of actings out and their usually rapid
resolutions >> (translated from Vedrinne). They make a brief overview
of french psychiatric emergencies departments organization in France e
ither in psychiatric hospitals or in general hospitals. They report th
e Nancy psychiatric emergencies room's experience, which was born in 1
987 and is based on an agreement between the psychiatric << secteurs >
> and the general hospital. This agreement provides psychiatrists and
psychiatric nurses 24h/24, working in a psychiatric room within the me
dical emergencies department. This experience agrees with the recent f
rench law about psychiatric emergencies.
