Abstract

Several findings from Argentina provide compelling evidence of the need for more rational use of antimicrobial agents. Thus, a multidisciplinary antimicrobial treatment committee for the development of a hospital-wide intervention program was formed to optimize the quality of antibiotic use in hospitals. Four successive steps were developed during 6-month periods: baseline data collection, introduction of a prescription form, education, and prescribing control. Sustained reduction of drug consumption was shown during the study (R2=0.6885; P=.01). Total cost savings was 913,236 US dollars. To estimate the consumption of cefepime and aminopenicillin-sulbactam in relation to that of the third-generation cephalosporins, 2 indices were calculated: Icfp and Iams, respectively. Decreasing resistance to ceftriaxone by Proteus mirabilis and Enterobacter cloacae proved to be associated with increasing Icfp. Decreasing rates of methicillin-resistant Staphylococcus aureus were related to increasing Iams. The present study indicates that a systematic program performed by a multidisciplinary team is a cost-effective strategy for optimizing antibiotic prescribing.
