Important updates

PECARN head injury decision rule has high sensitivity for identifying children with clinically important traumatic brain injury

An observational study of 20,137 children attending emergency departments with head injury found that the PECARN head injury decision rule had 99% point validation sensitivity to detect clinically important traumatic brain injury in children aged 2 years or older and 100% sensitivity in those under 2 years.

The study also confirmed high sensitivity rates for two alternative head injury decision rules in children: the CATCH rule for identifying the need for neurological intervention and the CHALICE rule for detecting clinically significant intracranial injury.
