National characteristics, etiology, and inpatient outcomes of pediatric traumatic brain injury: a KID study.

Abstract

Traumatic brain injury (TBI) in pediatric patients is a major burden to public health. Understanding clinical associations with severity and short hospitalization (≤ 1day length of stay) is needed to better inform management paradigms and optimize triage. A retrospective review of the Kids' Inpatient Database (KID) was performed for all data reported between 2006 and 2012 for TBI patients aged ≤ 20years. Univariate and multivariate regression analyses were performed to identify predictive factors of trauma severity and short hospitalization. A total of 220,777 pediatric TBI cases were identified, with the majority of cases being boys (66%) with a mean age of 11.5years. Mean length of stay was 5.0days, with 25% discharged within 1day, and 83% routinely discharged home. In-hospital mortality occurred in 4% of cases. More severe TBI presentations were significantly and independently associated with older age, weekend admissions, hospital transfers, and in patients with chronic conditions and neurological issues (all P < 0.01). There were 38% of admission that were short hospitalizations. Younger age, male gender, less chronic conditions, fall and assault etiologies, and with milder injury severity all significantly and independently predicted greater likelihood of short hospitalization. The severity of pediatric TBI admissions to the hospital can be impacted by a number of parameters. Furthermore, there exists a subset of clinical associations for short hospitalization admissions. Proactive identification of these parameters at time of presentation will assist in optimizing the management of pediatric TBI].
