Is the “practice style” hypothesis relevant for general practitioners? An analysis of antibiotics prescription for acute rhinopharyngitis

We observed that a large part of the total variation was due to intra-physician variability (70%). It is patient characteristics that largely explain the prescription, even if GP or practice setting characteristics (location, level of activity, network participation, continuing medical education) and environmental factors (visit from pharmaceutical sales representatives) also exert considerable influence. This suggests that MPV are partly caused by differences in the type of dissemination of medical information and this may help policy makers to identify and develop facilitators for promoting better use of antibiotics in France and, more generally, for influencing GP practices when it is of interest.
