Abstract

PURPOSE:

To assess antibiotic selection, administration, and prescribing practices in emergency departments across a large hospital system using evidence-based practices and susceptibility patterns.

METHODS:

This retrospective data review was conducted using health system-level electronic data compiled from 145 emergency departments (EDs) across the United States. Data were examined for national generalizability, most common diagnoses of infectious origin seen in nonadmitted patients in the ED, most commonly administered antibiotics in the ED, and geographically defined areas' unique patterns of antibiotic resistance and susceptibility.

RESULTS:

More than 627,000 unique patient encounters and 780,000 antibiotic administrations were assessed for trends in patient demographics, antibiotics administered for a diagnosis of infectious origin, and corresponding susceptibility patterns. Results indicated that practices in the EDs of this health system aligned with evidence-based practices for streptococcal pharyngitis, otitis media, cellulitis, and uncomplicated urinary tract infections.

CONCLUSION:

These results provide a representative sample of the current state of practices within many EDs across the United States for nonadmitted patients. A similar data reconstruction can be completed by other health systems to assess their prescribing practices in the ED to improve and elevate care for patients visiting the emergency room and treated as outpatients.
