PurposeThe purpose of this study was to evaluate the time to medication administration, clinical effect, and safety of a recent Pharmacy and Therapeutics Committee-approved change in the administration of levetiracetam from intravenous piggyback (IVPB) over 15 min to undiluted intravenous push (IVP) over 2-5 min at a large academic medical center.MethodsThe primary outcome was the time from order verification to the administration of IVP levetiracetam versus IVPB levetiracetam. The secondary outcome was any benzodiazepine administered in the time between levetiracetam order verification and administration in both groups. Adult patients admitted to the neuro-spine intensive care unit in the 6 months prior to and after the policy change, and who received at least one dose of 1000 mg or higher of IVP or IVPB levetiracetam for active seizures, were included in this retrospective, observational, institutional review board-approved study. Data were analyzed using descriptive statistics, χ2, and the Mann-Whitney U-test as appropriate.ResultsOf the 2055 hospital-wide levetiracetam doses ordered within the study period, 316 doses were screened for enrollment and 160 were enrolled with 60 and 100 patients assigned to the IVP and IVPB groups, respectively. There were no differences between the groups at baseline. The majority of the population was male, 57 years old, had no significant renal dysfunction (defined as a creatinine clearance of less than 60 ml/min), and had a seizure etiology of malignancy or traumatic brain injury. A significant reduction in the time to administration of levetiracetam was found with IVP compared with IVPB administration (28 vs. 80 min, p < 0.0001). A subsequent reduction in patients who received benzodiazepines in the interim of levetiracetam order verification and administration was also associated with IVP compared with IVPB (2% vs. 13%, p = 0.042). There were no differences found in the rates of adverse effects between groups.ConclusionsAdministration of levetiracetam doses up to 2000 mg via IVP is a safe method of administration that results in a reduction of time to medication administration and a reduction of benzodiazepine use.© 2021.
