This study aimed to evaluate the behavior of the physicians who attend to patients with community infections who are responsible for most of the antibiotic prescriptions made in the community setting. Furthermore, the evolution over the last 10 years in regards to the treatment habits of the most frequent infections in Primary Health Care (PHC) was studied and prescription behaviors were analyzed in relationship to the acquaintance and attitude of the participating physicians. A data collection sheet from 1,411 prescriptions made by 855 physicians from different specialties was used to conduct the study. This represents a statistically significant sample nationwide both from the point of view of the physicians involved in the treatment of infectious diseases in PHC as well as regarding to the prescriptions they have written. The study reveals the amplitude of respiratory and pararespiratory disease with oral antimicrobial agents, particularly beta-lactamics, and the significant advance in the last 10 years in the use of amoxicillin and clavulanic acid as treatment of choice. Treatment duration was somewhat longer while the number of containers prescribed was less than in the previous study. This would be related to the use of more spaced doses of the antimicrobial agents. Furthermore, the study reveals some discrepancies between attitudes and events of the physicians in the approach to certain diagnoses. Key words: Behavior. Primary care physicians. Prescription. Antimicrobials agents.
