Pharmacist driven antibiotic redosing in the emergency department.

Study Objective: Determine whether an expanded emergency medicine (EM) pharmacist scope of practice reduces the frequency of major delays in subsequent antibiotic administration in patients boarded in the emergency department (ED).

Methods: A pre-post, quasi-experimental study conducted from November 2019-March 2020 at a single-center tertiary academic medical center following the implementation of an expanded EM pharmacist scope of practice. Adult patients were included if they received an initial antibiotic dose in the ED and deemed to be high-risk.
