[The new nursing professions in psychiatry: One man's dream, another man's nightmare?]

The deployment of case management and advanced nursing practice is shaking up the roles of the various professionals on mental health teams, and the usual organization of care in psychiatry. These changes can be perceived as either positive or worrying, depending on each individual's role and position. For the past 3 years, the mobile teams of the Centre rive gauche cluster at Le Vinatier hospital have been organized according to the principles of Flexible Assertive Community Treatment, and include an advanced practice nurse (APN) on their staff. The roles of the case manager and the APN have been rethought. A number of measures have facilitated the implementation of these new functions.
