Adult Brain Injury Guidelines (BIG) were applied to a pediatric TBI population at a single center, and a modified pediatric-specific version was developed. BIG for Kids (kBIG) safely reduces resource utilization while minimizing misclassification risk in this pediatric population.
BIG guidelines for SMALL humans
This retrospective cohort study evaluated the applicability of the adult Brain Injury Guidelines (BIG) to pediatric patients with TBI and developed a modified guideline, BIG for Kids (kBIG), tailored to pediatric-specific injury patterns. The cohort included 1,894 patients <18yo with CT-confirmed skull fracture and/or ICH, treated between January 2018 and April 2024 at a Level 1 pediatric trauma center. The adult BIG was applied to this cohort, with misclassification defined as low/moderate risk patients (BIG 1-2) requiring neurosurgical intervention. Initial misclassification rates were 0% for BIG 1 and 1.4% for BIG 2. Informed by these findings, researchers developed kBIG by adjusting criteria such as minor skull fractures, epidural hematomas, neuro exam findings, and injury mechanism. The modified kBIG reduced the misclassification rate in moderate-risk (kBIG 2) patients to 0.8%, maintaining 0% in low-risk (kBIG 1) patients.
The study demonstrates strong methodological rigor, but limitations include a retrospective single-center design and lack of prospective validation. Overall, kBIG shows promise in reducing unnecessary imaging, transfers, and neurosurgical consults in pediatric TBI management while maintaining patient safety.
How does this change my practice?
There are some important differences to note with kBIG compared to BIG, including stratification of type of skull fracture, reclassification of small epidural bleed to low risk in kids, a tighter definition of abnormal neurological findings in preverbal kids, and incorporation of mechanism of injury. While not yet externally validated, this study informs my decision-making and may help reduce unnecessary repeat head CTs, low-risk transfers, and neurosurgery consults for stable kBIG 1 patients.
