Insights

In children with minor head injuries, the Pediatric Emergency Care Applied Research Network (PECARN) intermediate-risk criteria did not predict computed tomography (CT) scan decisions. Infant age (<3 months) was the sole significant predictor for CT scans.

Area of Science:

  • Pediatric emergency medicine
  • Radiology
  • Clinical decision-making

Background:

  • Minor head injury (MHI) in children often necessitates careful evaluation to rule out serious conditions.
  • The Pediatric Emergency Care Applied Research Network (PECARN) provides prediction rules to guide management, including computed tomography (CT) decisions.
  • Identifying predictors for CT scans in intermediate-risk pediatric MHI patients is crucial for optimizing resource utilization and patient care.

Purpose of the Study:

  • To determine the predictors associated with the decision to perform a computed tomography (CT) scan in children with a minor head injury (MHI).
  • To evaluate the role of Pediatric Emergency Care Applied Research Network (PECARN) intermediate-risk criteria in guiding CT scan decisions for pediatric MHI.
  • To identify key clinical factors influencing CT scan performance in this specific patient population.

Main Methods:

  • A 1-year, cross-sectional study was conducted in an Italian pediatric emergency department.
  • The study included children presenting within 24 hours of an MHI who met PECARN intermediate-risk criteria.
  • Data on clinical variables and CT scan decisions were collected and analyzed.

Main Results:

  • A total of 308 children were included, with 47% younger than 2 years.
  • CT scans were performed in 13% of cases; 1.3% had a clinically important traumatic brain injury (ciTBI).
  • Neither single nor multiple PECARN intermediate-risk predictors were associated with the decision to perform a CT scan. The strongest predictor was infant age (<3 months), with an odds ratio of 18.1.

Conclusions:

  • The PECARN intermediate-risk predictors showed limited influence on the decision to perform a CT scan in children with MHI.
  • Infant age, specifically being younger than 3 months, was the only significant clinical factor associated with the decision to obtain a CT scan.
  • These findings suggest that clinical judgment, particularly regarding very young infants, plays a more substantial role than PECARN criteria in CT scan decisions for pediatric MHI.
