Insights
The PECARN TBI rules accurately identify children with minor head injuries who can safely avoid CT scans. This validation confirms their effectiveness in managing pediatric traumatic brain injury (TBI) cases.
Area of Science:
- Pediatric Emergency Medicine
- Neurology
- Radiology
Background:
- The Pediatric Emergency Care Applied Research Network (PECARN) developed age-based clinical prediction rules to identify children at low risk for significant traumatic brain injury (TBI).
- These rules aim to reduce unnecessary computed tomography (CT) scans in pediatric patients with head injuries.
Purpose of the Study:
- To independently validate the accuracy and effectiveness of the PECARN TBI age-based prediction rules.
- To assess the rules' ability to identify children with minor blunt head trauma who can safely avoid CT scans.
Main Methods:
- A cross-sectional study was conducted in two pediatric emergency departments in the USA and Italy.
- 2439 children presenting with head injuries and a Glasgow Coma Score of ≥14 were assessed using PECARN TBI clinical predictors.
- Clinically important TBI was defined by severe outcomes such as death, prolonged intubation, neurosurgery, or extended hospitalization.
Main Results:
- Of the 2439 children included, 19 (0.8%) had a clinically important TBI.
- The PECARN TBI prediction rules demonstrated 100% sensitivity and 100% negative predictive value for identifying children with clinically important TBI.
- None of the children with clinically important TBI were classified as very low risk by the rules.
Conclusions:
- The age-based PECARN TBI prediction rules were accurately validated in an external cohort.
- These rules are effective in identifying children at very low risk for significant TBI, aiding CT decision-making for minor head trauma.
Objective:
The Pediatric Emergency Care Applied Research Network (PECARN) traumatic brain injury (TBI) age-based clinical prediction rules identify children at very low risk of a significant head injury who can safely avoid CT. Our goal was to independently validate these prediction rules.
Design:
Cross-sectional study.
Setting:
Two paediatric emergency departments located in USA and in Italy.
Patients:
All children presenting within 24 h of a head injury with a Glasgow Coma Score of ≥14.
Intervention:
Assessment of PECARN TBI clinical predictors.
Main Outcome Measure:
Clinically important TBI defined as head injury resulting in death, intubation for >24 h, neurosurgery or two or more nights of hospitalisation for the management of head trauma.
Results:
During the study period, we included 2439 children (91% of eligible patients), of which 959 (39%) were <2 years of age and 1439 (59%) were male. Of the study patients, 373 (15%) had a CT performed, 69 (3%) had traumatic findings on their CT and 19 (0.8%) had a clinically important TBI. None of the children with a clinically important TBI were classified as very low risk by the PECARN TBI prediction rules (overall sensitivity 100%; 95% CI 83.2% to 100%, specificity 55%, 95% CI 52.5% to 56.6%, and negative predictive value 100%, 95% CI 99.6% to 100%).
Conclusions:
In our external validation, the age-based PECARN TBI prediction rules accurately identified children at very low risk for a clinically significant TBI and can be used to assist CT decision making for children with minor blunt head trauma.
