Indications for brain computed tomography and hospital admission in pediatric patients with minor head injury: how much can we rely upon clinical findings?
OBJECTIVE
The aim of this study was to describe the characteristics of patients with a minor head injury (MHI) who were admitted to a pediatric emergency unit and to identify the clinical signs and symptoms that most reliably predict the need for cranial computed tomography (CCT) and hospital admission following MHI.


METHODS
All patients were retrospectively evaluated according to age, gender, details of injury, presenting symptoms, physical examination findings, radiological investigations ordered and results, length of stay, outcome of the injury and hospitalization rates.


RESULTS
The factors affecting indications for computed tomography and hospitalization were retrospectively analyzed in 916 patients--585 males and 331 females, aged between 1 month and 15 years (mean: 5.01 +/- 3.58 years), with MHI. A multivariate analysis revealed significant correlations between CCT abnormalities and Glasgow Coma Scale scores of 13 or 14, headache, posttraumatic amnesia, blurred vision, cephalohematomas, periorbital ecchymoses, otorrhea and abnormal neurological findings. CCT abnormalities were identified in 67 (19.8%) of the 338 CCT scans. Twenty of the 67 patients (29.9%) with CCT scan abnormality had no clinical signs. Of all cases, 125 (13.6%) were hospitalized, 617 (67.4%) were treated as outpatients, and 174 (19.0%) left the emergency department based on a personal decision.


CONCLUSIONS
Some clinical risk factors can be used as predictors of abnormalities in CCT scans following MHI, but the absence of such clinical findings does not exclude the possibility of intracranial injuries.
