Conception et évaluation d'une intervention brève « alimentation et prévention cardiovasculaire » en médecine de premier recours

The goal of our project was to assess acceptability and feasibility of a 5-step brief intervention (BI) on diet and coronary heart disease (CHD) prevention by general practitioners in a primary care setting. The intervention process and its acceptability by patients and physicians were assessed by standardised interviews and questionnaires, measuring the proportion of patients included, BI duration, perceived obstacles, usefulness and relevance of BI, patients' knowledge and planned behavior change. Of 99 eligible patients, 76 (77 %) participated and 48 received the BI, which took 5-10 minutes in the consultation. Three of the five steps were usually (38 %) performed. The five physicians were interested and motivated but mentioned lack of time. Most patients (77 %) said they had learned something new about their diet in relation to CHD, and 64 % were able to express at least one dietary habit they planned to change. Ninety-eight percent considered it was their physician's role to discuss their diet to prevent CHD. However, BI's implementation proves difficult in physicians' routine.
