Known Information

By some estimates, up to half of all hospitalized patients in the US receive antibiotics and up to half of antimicrobial use may be inappropriate.1 There is a causal relationship between inappropriate antimicrobial use and resistance; changes in antimicrobial use lead to parallel changes in the prevalence of resistance.2 The CDC has recommended a more judicious use of available antibiotic agents and one way to accomplish this is to identify patients who have been erroneously labeled as penicillin allergic. Penicillin allergy testing can be a safe and effective strategy to reduce the use of broad spectrum antibiotics and can help modify antibiotic selection.3
