Table 1: Patient Characteristics of Pediatric Traumatic Brain Injury (TBI) Patients studied using an Artificial Neural Network.
Our outcome of interest is clinically-relevant TBI, a composite of several variables as defined by the PECARN (Pediatric Emergency Care Applied Research Network) investigators. Clinically-relevant TBI included any of the following: 1) Neurosurgical procedure 2) Intubated > 24 hours as direct result of the head trauma 3) Hospitalization ≥ 48 hours, and 4) Death due to TBI.
