[The addiction patient in the family physicians' practice: tools and skills for a successful performance].

Addiction patients are usually perceived as problematic patients in primary care practices: Encounters often are time-consuming and the approach to the patient is difficult. Moreover, patients sometimes are hiding their addictive behaviour and behave shameful. Other barriers are a lack of experience in communication skills among physicians or their own addictive behaviour. Nevertheless, to diagnose and treat addiction as early as possible is an important task for family doctors, as patients' confidence in them is an important factor to induce a behaviour change. We present four screening tests for the early diagnosis of addiction to alcohol (AUDIT, AUDIT-C, CAGE, SMAST-G) and discuss their strengths and shortcomings. The family doctor's practice is also a useful setting for brief interventions based on motivational interviewing (MI) techniques and the transtheoretical model of behaviour change (TTM). We shortly introduce to these techniques and attitudes using addiction to alcohol and nicotine as examples, and we present innovative methods as "defined drinking" and new quit smoking methods. A respectful attitude towards the patient and communication skills seem to be key factors for family physicians to successfully approach their addiction patients.
