Epidemiology of Critical Interventions in Children With Traumatic Intracranial Hemorrhage.

OBJECTIVE

To estimate rates of critical medical and neurosurgical interventions and resource utilization for children with traumatic intracranial hemorrhage (ICH).

METHODS

This was a retrospective study of children younger than 18 years hospitalized in 1 of 35 hospitals in the Pediatric Health Information System from 2009 to 2019 for ICH. We defined critical intervention as a critical medical (hyperosmotic agents and intubation) or neurosurgical intervention. We determined rates of critical interventions, intensive care unit (ICU) admission, and repeat neuroimaging. We used hierarchical logistic regression to identify high-level factors associated with undergoing critical interventions, controlling for hospital-level effects.

RESULTS

There were 12,714 children with ICH included in the study. Median (interquartile range) age was 4.3 (0.7-11.0) years. Twelve percent (n = 1470) of children underwent a critical clinical intervention. Critical medical interventions occurred in 10% (n = 1219), and neurosurgical interventions occurred in 3% (n = 419). Intensive care unit admission occurred in 44% (n = 5565), whereas repeat neuroimaging occurred in 40% (n = 5072). Among ICU patients, 79% (n = 4366) did not undergo a critical intervention. Of the 11,244 children with no critical interventions, 39% (n = 4366) underwent ICU admission, and 37% (n = 4099) repeat neuroimaging. After controlling for hospital, children with isolated subdural (P = 0.013) and isolated subarachnoid (P < 0.001) hemorrhage were less likely to receive critical interventions.

CONCLUSIONS

Critical medical interventions occurred in 10% of children with ICH, and neurosurgical interventions occurred in 3%. Intensive care unit admission and repeat neuroimaging are common, even among those who did not undergo critical interventions. Selective utilization of ICU admission and repeat neuroimaging in children who are at low risk of requiring critical interventions could improve overall quality of care and decrease unnecessary resource utilization.
