Clinical management of patients with minor head injuries.

Background: Injuries are a focus of public health practice because they pose a serious health threat, occur frequently, and are preventable. Globally, thousands of people attend their local Emergency Department daily after suffering a head injury. Early diagnosis and appropriate management improves outcomes but is sometimes more difficult to achieve than might be imagined. Of all types of injury, those to the brain are among the most likely to result in death or permanent disability. Estimates of traumatic brain injury (TBI) incidence, severity, and cost reflect the enormous losses to individuals, their families, and society. The reduction in the number and severity of injuries offers a cost-effective manner in which to improve the health status of populations.

Methods: We prospectively studied 485 consecutive patients of traumatic brain injury out of which 280 with GCS of 13, 14, and 15 were subjected to routine early CT scan of head after 4 hours of reporting to Emergency Department. Patients with penetrating head injury were excluded.

Results: 15 % of patients had abnormal CT Scans and only 4% needed surgical intervention. Though a small number of patients harbour potentially lethal intracranial lesions yet, most of these cases are salvageable if diagnosed early and proper treatment.

Conclusion: This study reveals that the current practice in the some countries of risk stratification of adult MHI based on skull radiography need to be replaced by slightly modified versions of the Canadian CT rule/NICE guidelines. This will result in a large reduction in skull radiography and will be associated with modest increases in CT and admissions rates. The authors also believe that early CT Scanning can detect intracranial lesions and will reduce unnecessary hospital admissions.
