This project aims to study the attidudes and practices of general practitioners regarding antibiotic resistance. It seeks to understand how this public health issue translates into clinical pratices (specifically in their antibiotic prescriptions) and what social and professional factors may influence their attitude towards this problem. To this end, it relies on the 4th Panel of observations of pratices and conditions of exercice in general medecine, particularly wave 5 (focused on antibiotic resistance and antiobiotic prescriptions), as well as waves 1 and 6 (which provide information on the organization of the practice and the framework of practice) and wave 3 ( on physicians' attitudes towards prevention).
