title: Computed tomography for evaluation of mild to moderate pediatric trauma: are we overusing it?
abstract: Computed tomography (CT) is used liberally in the evaluation of pediatric trauma, even of low or moderate severity, because clinical examination of pediatric patients is considered unreliable. Appropriate utilization of valuable resources is essential in a cost-conscious medical era. The objective of this study is to determine if children with mild to moderate trauma are evaluated by more CT scans than adults with injuries of similar severity. Altogether, 108 pediatric patients less than 7 years old were matched according to mechanism of injury, Injury Severity Score (ISS), and the six individual body-region Abbreviated Injury Scores with adult patients admitted over the same 2-year period. All these patients had mild or moderate injuries (mean ISS 3.3 +/- 3.4). Pediatric patients had significantly more CT scans than adults, mostly because of a more liberal use of abdominal CT. CT scans of multiple body areas on the same patient were used more frequently in children but failed to identify more injuries compared to adults. None of the pediatric patients required an operation for abnormalities identified by CT. No differences were observed in morbidity, mortality, length of hospital stay, or length of intensive care unit stay for the two groups. It was concluded that a liberal policy of CT scanning for pediatric patients with a low ISS leads to increased resource consumption with no obvious diagnostic or treatment benefit.
