Intravenous push antibiotics in the emergency department: Education and implementation

Abstract

Abstract Purpose Intravenous push antibiotics can serve as an alternative to intravenous piggyback antibiotics while providing the same pharmacodynamics and adverse effect profile, easing shortage pressures and decreasing order to administration time, as well as representing a potential cost savings. The purpose of this study was to determine whether intravenous push antibiotics could decrease the time from an order to the start of administration compared to piggyback antibiotics in emergency departments. This study also measured the cost savings of antibiotic preparation and administration and assessed nursing satisfaction when using intravenous push antibiotics. Methods Sample instances of use of intravenous push and piggyback antibiotics were identified. Patients were included if they were 18 years of age or older and received at least a single dose of intravenous push or piggyback ceftriaxone, cefepime, cefazolin, or meropenem in one of the institution’s emergency departments. The primary outcome of the study was to compare the time from the order to the start of administration of intravenous push vs piggyback antibiotics. The secondary outcome was to compare the cost of antibiotic preparation for the 2 methods. Results The intravenous push and piggyback groups each had 43 patients. The time from the order to the start of administration decreased from 74 (interquartile range, 29-114) minutes in the piggyback group to 31 (interquartile range, 21-52) minutes in the push group (P = 0.003). When the estimated monthly cost savings for ceftriaxone, cefepime, and meropenem were added together, across the emergency departments, an estimated $227,930.88 is saved per year when using intravenous push antibiotics. Conclusion Intravenous push antibiotics decrease the time from ordering to the start of administration and result in significant cost savings.
