Advanced nursing practices are procedures enabling nurses to carry out, in a structured and predefined manner, tasks usually entrusted to doctors. Introduced in France by the Berland reports of 2003 and 2006, advanced nursing practices remain under-developed in the fields of psychiatry and addictology. In this context, Lille regional and university hospital has set up an outpatient programme for alcohol withdrawal, a scheme coordinated by a nurse, authorised to modifythe treatment dosage according to the patient's clinical state and who is supported by a network of caregivers during the period of medicalised withdrawal.
