RESUMO
BACKGROUND: Differences in injury patterns in children suggest that life-threatening chest injuries are rare. Radiation exposure from computed tomography increases cancer risk in children. Two large retrospective pediatric studies have demonstrated that thoracic computed tomography can be reserved for patients based on mechanism of injury and abnormal findings on chest radiography. OBJECTIVE: Implement a decision rule to guide utilization of thoracic computed tomography in the evaluation of pediatric blunt trauma, limiting risk of unnecessary radiation exposure and clinically significant missed injuries. METHODS: A protocol for thoracic computed tomography utilization in pediatric blunt trauma was implemented using a Plan-Do-Study-Act cycle at our Level I pediatric trauma center, reserving thoracic computed tomography for patients with (1) mediastinal widening on chest radiography or (2) vehicle-related mechanism and abnormal chest radiography. We modified our resuscitation order set to limit default imaging bundles. The medical record and trauma registry data were reviewed for all pediatric blunt trauma patients (younger than 18 years) over a 30-month study period before and after protocol implementation (May 2017 to July 2018 and February 2019 to April 2020), allowing for a 6-month implementation period (August 2018 to January 2019). RESULTS: During the study period, 1,056 blunt trauma patients were evaluated with a median (range) Injury Severity Score of 5 (0-58). There were no significant demographic differences between patients before and after protocol implementation. Thoracic computed tomography utilization significantly decreased after implementation of the protocol (26.4% [129/488] to 12.7% [72/568; p < .05]), with no increase in clinically significant missed injuries. Protocol compliance was 88%. CONCLUSIONS: Application of decision rules can safely limit ionizing radiation in injured children. Further limitations to thoracic computed tomography utilization may be safe and warrant continued study due to the rarity of significant injuries.

BACKGROUND: The purpose of this study was to provide an evaluation of a performance improvement initiative that operationalized universal concussion screening for all pediatric trauma admissions at a Level I pediatric trauma center. Mild traumatic brain injury may be difficult to identify in injured children. We implemented a screening tool to identify the risk for concussion after traumatic injury and to improve access to cognitive evaluation and intervention in children. Prior to implementation of our screening tool, children admitted without obvious head injury or those younger than 12 years were not being screened for concussion risk. METHODS: We employed a nurse-driven screening tool, derived from the Centers for Disease Control and Prevention Acute Concussion Evaluation, on all pediatric trauma patients ages 0-17 years. The screening tool identifies symptoms of physical, cognitive, sleep, or emotional deficits and prompts a cognitive evaluation with concussion education. The tool was administered by nursing and tracked in the electronic medical record. RESULTS: Key stakeholders were interviewed to identify workflow barriers and education gaps following implementation. Enhancements to the electronic medical record and refocused nursing education improved compliance from 41% in the first 12 months to 91% at 24 months post-implementation (p < .001). The increasing number of evaluations additionally resulted in overall more cognitive evaluations as an initial step in identifying and treating previously unrecognized traumatic brain injury. CONCLUSIONS: A pediatric concussion screening tool is simple to administer, applies to all developmental ages, and improves diagnostic capture of traumatic brain injury in pediatric trauma when administered by nurses with support through the electronic medical record.

PURPOSE: Venous thromboembolism (VTE) in injured children is rare, but sequelae can be morbid and life-threatening. Recent trauma society guidelines suggesting that all children over 15 years old should receive thromboprophylaxis may result in overtreatment. We sought to evaluate the efficacy of a previously published VTE prediction algorithm and compare it to current recommendations. METHODS: Two institutional trauma registries were queried for all pediatric (age < 18 years) patients admitted from 2007 to 2018. Clinical data were applied to the algorithm and the area under the receiver operating characteristic (AUROC) curve was calculated to test algorithm efficacy. RESULTS: A retrospective review identified 8271 patients with 30 episodes of VTE (0.36%). The VTE prediction algorithm classified 51 (0.6%) as high risk (> 5% risk), 322 (3.9%) as moderate risk (1-5% risk) and 7898 (95.5%) as low risk (< 1% risk). AUROC was 0.93 (95% CI 0.89-0.97). In our population, prophylaxis of the 'moderate-' and 'high-risk' cohorts would outperform the sensitivity (60% vs. 53%) and specificity (96% vs. 77%) of current guidelines while anticoagulating substantially fewer patients (373 vs. 1935, p < 0.001). CONCLUSION: A VTE prediction algorithm using clinical variables can identify injured children at risk for venous thromboembolic disease with more discrimination than current guidelines. Prospective studies are needed to investigate the validity of this model. LEVEL OF EVIDENCE: III-Clinical decision rule evaluated in a single population.

BACKGROUND: Trauma-induced coagulopathy seen on rotational thromboelastometry (ROTEM) is associated with poor outcomes in adults; however, this relationship is poorly understood in the pediatric population. We sought to define thresholds for product-specific transfusion and evaluate the prognostic efficacy of ROTEM in injured children. METHODS: Demographics, ROTEM, and clinical outcomes from severely injured children (age, < 18 years) admitted to a Level I trauma center between 2014 and 2018 were retrospectively analyzed. Receiver operating characteristic curves were plotted and Youden indexes were calculated against the endpoint of packed red blood cell transfusion to identify thresholds for intervention. The ROTEM parameters were compared against the clinical outcomes of mortality or disability at discharge. RESULTS: Ninety subjects were reviewed. Increased tissue factor-triggered extrinsic pathway (EXTEM) clotting time (CT) >84.5 sec (p = 0.049), decreased EXTEM amplitude at 10 minutes (A10) <43.5 mm (p = 0.025), and decreased EXTEM maximal clot firmness (MCF) <64.5 mm (p = 0.026) were associated with need for blood product transfusion. Additionally, EXTEM CT longer than 68.5 seconds was associated with mortality or disability at discharge. CONCLUSION: Coagulation dysregulation on thromboelastometry is associated with disability and mortality in children. Based on our findings, we propose ROTEM thresholds: plasma transfusion for EXTEM CT longer than 84.5 seconds, fibrinogen replacement for EXTEM A10 less than 43.5 mm, and platelet transfusion for EXTEM MCF less than 64.5 mm. LEVEL OF EVIDENCE: Prognostic, Level III; Therapeutic, Level IV.
