Misuse of Discharge Antimicrobial Prescription in the Emergency Department: An Observational Study at a Tertiary Care Center.

We conducted a restrospective cohort study of patients discharged from the emergency department at a tertiary care center with an antimicrobial prescription. More than half of the prescribed antimicrobials were misused and frequently inappropriate for various infectious diseases. In this study, we analyzed the physician-related and environment-related factors predicting misuse.
