Antimicrobial resistance has increasingly become a threat to patient safety in health care settings.1 Several studies have identified the inappropriate use of antimicrobials as important risk factor for antimicrobial resistance and the important area of opportunity for increasing patient safety and improving patient outcomes.2 High rates of antimicrobial use have been linked to high rates of antimicrobial resistance,3 and increased exposure to antimicrobials has been associated with an increased probability of colonization with resistant pathogens. It has also been shown that antimicrobial control results in significant cost savings4 and it may reduce antimicrobial resistance Surveys reveal that 25 - 33% of hospitalized patients receive antibiotics6 and that 22 - 65% of antibiotic use in hospitalized patients is inappropriate.7
