Abstract
INTRODUCTION
Severe traumatic brain injury (TBI) increases the risk of early posttraumatic seizures (EPTS). Guidelines suggest the use of prophylactic antiseizure agents, including levetiracetam. This study aims to evaluate the feasibility of using levetiracetam dosing based on Glasgow Comas Scale (GCS) scores with higher doses used for more severe TBI.
METHODS
Patients 6 months to 18 years old admitted to Penn State Hershey Children's Hospital (PSHCH) with a TBI who received levetiracetam for EPTS prophylaxis with at least one documented GCS score were included. Patients were divided into two cohorts: before and after implementation of the pediatric TBI Cerner PowerPlan at PSHCH which standardized levetiracetam dosing based on GCS scores. Primary outcome was appropriate dosing of levetiracetam based on GCS. Secondary outcomes included seizure occurrence and adverse effects.
RESULTS
Eighty-five patients were included: 42 in the pre-PowerPlan group and 43 in the post-PowerPlan group. Overall, 46 (54%) patients received the appropriate levetiracetam dose based on GCS (pre-PowerPlan, n = 19 [45%] vs. post-PowerPlan n = 27 [63%], p = 0.104). Sixty-four percent of severe TBI patients received appropriate levetiracetam dosing after implantation of the PowerPlan compared with 28% prior to the PowerPlan (p = 0.039). Three patients in each group experienced a seizure while on levetiracetam. Two patients experienced agitation and somnolence attributed to levetiracetam.
CONCLUSION
Levetiracetam dosing based on GCS scores in pediatric TBI patients is a novel approach, and dosing accuracy may be increased with use of a PowerPlan. Additional large-scale studies are needed to evaluate efficacy and safety of this approach prior to widespread implementation.
