![]() ![]() Such a policy makes skull radiography unnecessary in this subgroup. Thus, we suggest separating patients with a GCS of 13-14 into a different category and recommend performing CT in all those not improving within 4-6 h of injury. Patients with 13-14 GCS had a significantly higher incidence of initial loss of consciousness, of skull fracture, abnormal CT findings, need for hospital admission, delayed neurological deterioration and need for operation than patients with a GCS of 15. ![]() ![]() By contrast, the gender, the mechanism of injury, the occurrence of initial loss of consciousness, posttraumatic amnesia and coagulation disorders did not significantly increase the incidence of abnormal CT findings. A multivariate analysis showed that advanced age, a lower GCS (13-14) and the presence of skull fracture, and focal signs, significantly increased the incidence of abnormal computed tomography (CT) findings. We performed a retrospective study of 2484 consecutive patients with mild head injury (Glasgow Coma Scale score 13-15) who were seen during a period of 18 months.
