Primary objective: To assess feasibility and utility of neurocognitive testing of children evaluated and discharged from the ED with mild traumatic brain injury (MTBI).
Methods: Paediatric blunt trauma patients (aged 11-18 years) evaluated in the ED for MTBI and control patients with isolated lower extremity injury were prospectively enrolled. All patients were administered a validated neurocognitive test (ImPACT((c))). Wilcoxon sign rank tests were used to compare reported symptoms and neurocognitive performance between subjects and controls, as well as to matched normative data.
Results: Thirty-nine subjects and 46 controls were enrolled. The MTBI patients had a mean age of 13.9 years (53.8% male). An abnormal symptom score was reported in 89.7% of MTBI subjects (mean score = 29.4, normal <= 8), differing significantly (p < 0.05) from controls, in whom 39.1% demonstrated an abnormal score (mean score = 8.7). In all neurocognitive test domains, visual motor speed and reaction time, MTBI patients demonstrated lower scores than normative data (p < 0.05).
Conclusions: Patients with MTBI were more likely than control subjects to have scores on any or all neurocognitive domains below the 25th percentile and 10th percentile. In the ED setting, acute neurocognitive testing of MTBI in children is feasible. This highlights the importance of structured follow-up for this treated and released population.
