Trial Outcomes & Findings for Assess Safety and Efficacy of Levetiracetam(LEV;Keppra)for Seizure Prevention (NCT NCT00618436)

Assess Safety and Efficacy of Levetiracetam(LEV;Keppra)for Seizure Prevention

This was the number of patients in each group who demonstrated seizure activity during the course of the study

This is an 8 point validated scale that measures disability after brain injury. It is assessed through an in person exam or by phone interview at hospital discharge, 3 months and 6 months after injury. The categories are: 1 = dead; 2 = vegetative state; 3 = severe disability, low level; 4 = severe disability, high level; 5 = moderate disability, low level; 6 = moderate disability, high level; 7 = good recovery - low level; 8 = good recovery - high level. Specific questions and activities are assessed to determine into which category the patient falls.

The Disability rating scale (DRS) is frequently used in the rehabilitation literature as a measure of disability. It is a reliable, easily performed test that assesses 8 items (eye opening, verbalization, motor response, feeding, toileting, grooming, level of functioning, employability), and assigns each a numerical score ranging from 0 - 5 based on the category. The domains these 8 items are felt to assess include: alertness, cognition for self-care, dependence, and psychosocial adaptability. The scoring range is from 0-30, with increasing disability levels assigned to higher numerical values. The total DRS is then dichotomized into favorable (disability = none, mild, partial or moderate disability) and unfavorable (disability = moderately severe, severe, extremely severe, vegetative state, extreme vegetative state, death) outcomes. A DRS score of 0-6 was favorable, with any score greater than 6 categorized as unfavorable.
