Brief Summary:

The SAMBA study aims to assess the safety and cost comparison of the management of outpatient alcohol detoxification, between an advanced nurse protocol on the one hand (experimental group), and a GP-based treatment on the other hand (standard-of-care group).

In the advanced nurse (AN) group, nurses manage alcohol detox using a predefined protocol based on both the Cushman and CIWA-Ar scales. Depending on the Cushman and CIWA-Ar scores, which are calculated at every consultation, advanced nurse can adjust the diazepam dosing. In case of any serious adverse event or uncontrolled withdrawal complication, an addiction specialist stands in back-up and can be appealed to decide whether the outpatient detox can be continued or whether the patient has to be hospitalized. In the GP group, GPs can manage patients as they wish.

Arm Intervention/treatment
Experimental: Advanced Nurse (AN)
The outpatient detoxication procedure will be entirely managed by an advanced nurse team, using a predefined protocol decision algorithm. The protocol allows that the AN team autonomously manages the diazepam dosing during the detox period. Addiction physicians only intervenes in case of severe withdrawal symptoms or serious adverse events.
Procedure: Advanced Nurse (AN)
Protocoled AN-based management of detox

Active Comparator: General Practitioner (GP)
The outpatient detoxication procedure is entrusted to a GP who will manage patients and diazepam dosing as he/she thinks best ("as usual" control group)
Procedure: General Practitioner (GP)
'As usual' medical management of detox

Primary Outcome Measures :
  1. Number of patients considered in failure of outpatient alcohol detoxification period [ Time Frame: 15 days ]
    Hospitalization required (any cause) across the 15 days following the detox start

Secondary Outcome Measures :
  1. The total costs for each arm by cost-minimization [ Time Frame: during the 15 days of the outpatient alcohol detoxification ]
    All medical costs (visits, medications, hospitalizations, ambulance,..) resulting from the detoxification management

  2. Number of patients reporting at least one recovery in alcohol consumption [ Time Frame: during the 15 days of the outpatient alcohol detoxification ]
    alcohol consumption obtained from A-TLFB data

  3. Number of patients reporting at least one high alcohol intake [ Time Frame: during the 15 days of the outpatient alcohol detoxification ]
    High alcohol intake defined by consumption of more than 5 standard drinks per day

  4. Number of patients with adverse events [ Time Frame: during the 15 days of the outpatient alcohol detoxification ]
