Evaluation of Safety Outcomes of Undiluted Levetiracetam Intravenous Push Compared to Intravenous Piggyback.

Background: Breakthrough seizures and status epilepticus require urgent management. Administration of intravenous push (IVP) levetiracetam has been demonstrated to be safe as compared to intravenous piggyback (IVPB). This transition can potentially offer faster time to administration and reduced drug and material cost. The objective of this study was to observe safety of administration in patients receiving levetiracetam via IVP compared to IVPB in acute care settings. Methods: This is a multi-center, observational, retrospective cohort study of 1214 adult patients who received levetiracetam pre- and post-implementation of IVP over a 6 month timespan. Primary outcome was time from order verification to administration of urgent first-time doses. Secondary outcomes included time to administration of loading doses and cost. Safety outcome was infusion site related reactions. Results: Time from order verification to administration of urgent first-time doses pre- and post-implementation of IVP administration was reduced from 61 minutes to 47 minutes ( P =0.0002). Infusion site related reactions were observed in 6 out of 5432 doses in the IVPB arm and in 5 out of 4700 doses in the IVP arm ( P =1). Total estimated cost was $76,171.96 for the 5449 IVPB total doses and $11,484.33 for the 4721 IVP total doses. Conclusions: Transition from IVPB to IVP administration reduced time from order verification to administration of urgent first-time doses with both administrations having similar incidence of infusion site related reactions. Cost savings and improved workflow were observed. Levetiracetam administered via IVP may be considered as a safe alternative method of administration in the acute care setting.
