NASCIMENTO-CARVALHO, Cristiana M.. Outpatient antibiotic therapy as a predisposing factor for bacterial resistance: a rational approach to airway infections. J. Pediatr. (Rio J.) [online]. 2006, vol.82, n.5, suppl., pp.S146-S152. ISSN 1678-4782. http://dx.doi.org/10.1590/S0021-75572006000700004.
OBJECTIVES: To present evidence-based recommendations for the use of antibiotics for the treatment of the most common acute respiratory infections (ARI) and the available information on the importance of this type of management. SOURCES: MEDLINE and LILACS databases, technical publications by international organizations, national and international directives. The search terms acute respiratory infection, otitis, sinusitis, tonsillitis, pneumonia, antibiotic, guidelines and bacterial resistance were used. Articles cited by the articles selected were analyzed for information of interest. SUMMARY OF THE FINDINGS: Bacterial resistance has grown, to the extent that today it is recognized as a global public health problem. ARI are the most common cause of antibiotic usage within the community; yet a large proportion of these cases, compromising the upper (otitis, sinusitis, tonsillitis) or the lower airways (pneumonia), are the result of viral infections. Recommendations to rationalize the use of antibiotics in patients with ARI have the common objective of minimizing unnecessary antibiotic use, since "antibiotic pressure" is one of the factors triggering bacterial resistance. CONCLUSIONS: It is of great importance to differentiate among ARI patients those who will benefit from the use of antibiotics. The establishment of recommendations for the prescription of antibiotics is one strategy for minimizing the frequency of bacterial resistance.
