BACKGROUND: In Belgium, 82% of the population consumes alcohol occasionally while 10% consume in a way that can be seen as problematic. On a European level, only 8% of the people who can be characterized as having Alcohol Use Disorder (AUD) would have consulted professional assistance in the past year. In this context, the KCE (Belgian Health Care Knowledge Centre) has addressed multiple recommendations to health professionals to reduce the "treatment gap" concerning the patients' care: (1) encourage screening and preventative interventions, (2) promote the acquirement of communicational and relational competences (3) develop collaborations between professionals. The objective of this article is to better understand their functioning. METHOD: We format a non-systematic literature review concerning these recommendations. RESULTS: The implementation of these Brief Interventions programs in primary care is relevant due to the moderately positive impact on the frequency and quantity of alcohol consumption but both the quality of the therapeutic relationship and collaboration with the care network would optimize Brief Interventions. The quality of the therapeutic relationship alone appears to have an impact on therapeutic outcome. CONCLUSION: Training concerning patient-professional relationship is necessary to maximize the effectiveness of BIs.
