Brief interventions are recognized by WHO as effective for addressing the risk factors of noncommunicable diseases (NCDs), including smoking, alcohol consumption, insufficient physical activity, unhealthy diets and over- or underweight. There are, however, few data on the use of brief interventions or on the perspectives of health-service providers in the WHO European Region on the barriers to and facilitators of their delivery. This report is part of the BRIEF project of the WHO Regional Office for Europe. The aim of the project is to advance implementation and use of integrated brief interventions for NCD risk factors in primary care in the WHO European Region. The report of this mixed-method study presents the results of a questionnaire-based survey and in-depth interviews with primary-care providers on three main topics: current uptake of brief interventions by providers; barriers, facilitators and recommendations from providers for effective brief interventions in primary care; and policy recommendations for effective facilitation and implementation of brief interventions.
