3000 head injuries: a prospective study of patients admitted to Brisbane neurosurgical units.
A prospective epidemiological study of 3095 patients with head injury admitted to Brisbane neurosurgical units is presented. Falls were the commonest cause of injury overall (42%) but traffic accidents were the leading cause of severe head injury Glasgow Coma Scale ([GCS] 8 or less) and had a higher mortality (5.6%). Outcome was closely related to GCS, presence or absence and type of skull fracture, computed tomography (CT) scan findings and age. Overall mortality was 4.4%. Mortality for mild head injury (GCS 13-15) was 0.4%, moderately severe head injury (GCS 9-12) 10.5% and severe head injury (GCS 3-8) 34.5%. The poor outcome in old patients who fall and sustain a mild head injury is highlighted. Low risk criteria are identified and recommendations regarding admission and management policies are made.
