"Alcochoix+": controlled drinking within a structured programme - a cohort study in Switzerland (2019)

AIMS OF THE STUDY: Controlled drinking as a therapy goal for problematic alcohol use is still a matter for debate, especially with regard to dependent drinkers. Furthermore, few structured controlled drinking programmes have been evaluated. The aim of this study was to observe the evolution of excessive and dependent drinkers in a French-language six-step controlled drinking programme called "Alcochoix+".
METHODS: This was a cohort study of patients in four centres in the French-speaking part of Switzerland who were enrolled between May 2010 and September 2011, and evaluated before and up to 1 year after completion of the programme, according to criteria such as drinking habits, evolution of the Alcohol Use Disorder Identification Test (AUDIT) score and quality of life indicators. We considered the patients who chose not to be followed up to have unchanged alcohol consumption.
RESULTS: Recruitment was slow: 60 persons were enrolled, mostly middle-aged men, with excessive alcohol use / moderate alcohol dependence (median AUDIT score 20.5, median weekly alcohol consumption 350 g). Thirty-four participants (56.7%) completed the programme and their median weekly alcohol reduction was 160 g. The mean AUDIT score decreased to 14.1 points. Several aspects of quality of life improved. Changes were stable 1 year after the programme. Expressed satisfaction with the programme was high.
CONCLUSIONS: This six-step structured controlled drinking programme designed for excessive drinkers also attracted moderately dependent drinkers. Those who had participated fully in the study significantly reduced their alcohol consumption, with a slight improvement in their quality of life. Future studies should identify the barriers to problem drinkers integrating controlled drinking programmes, and to underline the role of these programmes for moderately dependent drinkers.
