Abstract

Objective: To describe the irrational use of antibiotics based on McIsaac criteria (Centor criteria modified by McIsaac), in a primary care facility. Methods: A cross-sectional descriptive study was conducted with the medical record of patients from 3 to 19 years old, treated in the emergency department (246), with the diagnoses of acute pharyngitis, acute tonsillitis, and acute upper respiratory infections from multiple sites and not specified. It was established as an inappropriate prescription if the physician indicated antibiotics with a score less than or equal to 1 out of 5 points or if he did not prescribe antibiotics with a score greater than or equal to 4 out of 5 points. Results: Inadequate use of antibiotics was found in 24.29% of emergency records. Antibiotics were prescribed in 160 patients, of which, amoxicillin was the most used (61.87%); followed by benzathine penicillin (28.12%) and in third place macrolides (8.12%). Conclusion: In the first level unit analyzed, it was found that the inappropriate use of antibiotics is superior to the estimated prevalence of streptococcal pharyngitis for the age group studied. Therefore, it is imperative that the necessary measures are taken at the institutional and community level to achieve its reduction and avoid the complications that result from it.
