Predicting Complicated Mild Traumatic Brain Injury in Adolescent Trauma to Enhance Clinical Decisions in Imaging.

BACKGROUND: The Pediatric Emergency Care Applied Research Network (PECARN) traumatic brain injury algorithm is used to identify children at low risk of clinically significant traumatic brain injuries to reduce computed tomography (CT) exposure. Adapting PECARN rules based on population-specific risk stratification has been suggested to improve diagnostic accuracy. OBJECTIVE: This study sought to identify center-specific patient variables, beyond PECARN rules, that may enhance the identification of patients requiring neuroimaging. METHODS: This single-center, retrospective cohort study was conducted from July 1, 2016, to July 1, 2020, in a Southwestern U.S. Level II pediatric trauma center. The inclusion criteria were adolescents (10-15 years), Glasgow Coma Scale (13-15), with a confirmed mechanical blow to the head. Patients without a head CT were excluded. Logistic regression was performed to identify additional complicated mild traumatic brain injury predictor variables beyond the PECARN. RESULTS: There were 136 patients studied; 21 (15%) presented with a complicated mild traumatic brain injury. Relative to motorcycle collision or all-terrain vehicle trauma (odds ratio [OR] 211.75, 95% confidence interval, CI [4.51, 9931.41], p < .001), an unspecified mechanism (OR 42.0, 95% CI [1.30, 1350.97], p = .03) and consult activation (OR 17.44, 95% CI [1.75, 173.31], p = .01) were significantly associated with complicated mild traumatic brain injury. CONCLUSIONS: We identified additional factors associated with complex mild traumatic brain injury, including motorcycle collision and all-terrain vehicle trauma, unspecified mechanism, and consult activation that are not in the PECARN imaging decision rule. Adding these variables may aid in determining the need for appropriate CT scanning.

What Makes a Trauma Patient "Pediatric"? Survey of Providers' Admission Decision Making for Pediatric Trauma Patients.

BACKGROUND: Only a fraction of pediatric trauma patients are treated in pediatric-specific facilities, leaving the remaining to be seen in centers that must decide to admit the patient to a pediatric or adult unit. Thus, there may be inconsistencies in pediatric trauma admission practices among trauma centers. OBJECTIVE: Describe current practices in admission decision making for pediatric patients. METHODS: An email survey was distributed to members of three professional organizations: The American Association for the Surgery of Trauma, Society of Trauma Nurses, and Pediatric Trauma Society. The survey contained questions regarding pediatric age cutoffs, institutional placement decisions, and scenario-based assessments to determine mitigating placement factors. RESULTS: There were 313 survey responses representing freestanding children's hospitals (114, 36.4%); children's hospitals within general hospitals (107, 34.2%), and adult centers (not a children's hospital; 90, 28.8%). The mean age cutoff for pediatric admission was 16.6 years. The most reported cutoff ages were 18 years (77, 25.6%) and 15 years (76, 25.2%). The most common rationales for the age cutoffs were "institutional experience/tradition" (139, 44.4%) and "physician preference" (89, 28.4%). CONCLUSION: There was no single widely accepted age cutoff that distinguished pediatric from adult trauma patients for admission placement. There was significant variability between and within the types of facilities, with noted ambiguity in the definition of a "pediatric" patient. Thresholds appear to be based primarily on subjective criteria such as traditions or preferences rather than scientific data. Institutions should strive for objective, evidence-based policies for determining the appropriate placement of pediatric patients.
