The determination that a particular head injury is "mild" or "low-risk" is usually made on clinical grounds. Observation at home or in the hospital has been the usual treatment for such patients. A recent report of excessive mortality among these patients with low-risk head injuries in some hospital settings suggests the need for improvement in diagnostic criteria. ⋯ These figures suggest that history and physical examination alone are not adequate to assess head injury or severity of risk and that the addition of a CT scan greatly improves patient assessment. Abnormalities on CT scans are so common in patients with a Glasgow Coma Scale score of 13 that head injuries in these patients should be classified as "moderate" rather than "mild" in severity and risk. Patients with normal CT scans should be considered for observation at home, allowing hospital personnel to devote full attention to the more seriously injured patients.
