The microbiological confirmation was 83.9%, totaling 11 species of microorganisms, one of which being multiresistant. The use of 14 different antimicrobials was observed with monotherapy in a minority of cases. Only two patients underwent five schemes. Mistake regarding prescription was not observed, but misconceptions about some doses, intervals and as an association were highlighted.Conclusion: the indicators analyzed showed no significant discrepancies when compared with other national or international studies. One perceives the need for further studies on the use of antimicrobials.
