Drug-usage evaluation: a system for the prospective evaluation of antibiotic utilization in minimum inhibitory concentration documented infections.

Large hospitals appear to have advantages in using specialized clinical practitioners to provide prospective reviews on drug therapy.

The minimal requirements are a microbiology laboratory, administrative support, and a pharmacy service committed to providing prospective patient oriented care.
