Lower incidence of blunt cerebrovascular injury among young, properly restrained children: An ATOMAC multicenter study.

BACKGROUND: Motor vehicle collision (MVC) remains a leading cause of injury and death among children, but the proper use of child safety seats and restraints has lowered the risks associated with motor vehicle travel. Blunt cerebrovascular injury (BCVI) is rare but significant among children involved in MVC. This study reviewed the incidence of BCVI after MVC causing blunt injury to the head, face, or neck, comparing those that were properly restrained with those that were not. METHODS: A prospective, multi-institutional observational study of children younger than 15 years who sustained blunt trauma to the head, face, or neck (Abbreviated Injury Scale score >0) and presented at one of six level I pediatric trauma centers from 2017 to 2020 was conducted. Diagnosis of BCVI was made either by imaging or neurological symptoms at 2-week follow-up. Restraint status among those involved in MVC was compared for each age group. RESULTS: A total of 2,284 patients were enrolled at the 6 trauma centers. Of these, 521 (22.8%) were involved in an MVC. In this cohort, after excluding patients with missing data, 10 of 371 (2.7%) were diagnosed with a BCVI. For children younger than 12 years, none who were properly restrained suffered a BCVI (0 of 75 children), while 7 of 221 (3.2%) improperly restrained children suffered a BCVI. For children between 12 and 15 years of age, the incidence of BCVI was 2 of 36 (5.5%) for children in seat belts compared with 1 of 36 (2.8%) for unrestrained children. CONCLUSION: In this large multicenter prospectively screened pediatric cohort, the incidence of BCVI among properly restrained children under 12 years after MVC was infrequent, while the incidence was 3.2% among those without proper restraint. This effect was not seen among children older than 12 years. Restraint status in young children may be an important factor in BCVI screening. LEVEL OF EVIDENCE: Prognostic and Epidemiological; Level IV.

Diagnostic accuracy of screening tools for pediatric blunt cerebrovascular injury: An ATOMAC multicenter study.

BACKGROUND: Blunt cerebrovascular injury (BCVI) is rare but significant among children. There are three sets of BCVI screening criteria validated for adults (Denver, Memphis, and Eastern Association for the Surgery of Trauma criteria) and two that have been validated for use in pediatrics (Utah score and McGovern score), all of which were developed using retrospective, single-center data sets. The purpose of this study was to determine the diagnostic accuracy of each set of screening criteria in children using a prospective, multicenter pediatric data set. METHODS: A prospective, multi-institutional observational study of children younger than 15 years who sustained blunt trauma to the head, face, or neck and presented at one of six level I pediatric trauma centers from 2017 to 2020 was conducted. All patients were screened for BCVI using the Memphis criteria, but criteria for all five were collected for analysis. Patients underwent computed tomography angiography of the head or neck if the Memphis criteria were met at presentation or neurological abnormalities were detected at 2-week follow-up. RESULTS: A total of 2,284 patients at the 6 trauma centers met the inclusion criteria. After excluding cases with incomplete data, 1,461 cases had computed tomography angiography and/or 2-week clinical follow-up and were analyzed, including 24 cases (1.6%) with BCVI. Sensitivity, specificity, positive predictive value, and negative predictive value for each set of criteria were respectively 75.0, 87.5, 9.1, and 99.5 for Denver; 91.7, 71.1, 5.0, and 99.8 for Memphis; 79.2, 82.7, 7.1, and 99.6 for Eastern Association for the Surgery of Trauma; 45.8, 95.8, 15.5, and 99.1 for Utah; and 75.0, 89.5, 10.7, and 99.5 for McGovern. CONCLUSION: In this large multicenter pediatric cohort, the Memphis criteria demonstrated the highest sensitivity at 91.7% and would have missed the fewest BCVI, while the Utah score had the highest specificity at 95.8% but would have missed more than half of the injuries. Development of a tool, which narrows the Memphis criteria while maintaining its sensitivity, is needed for application in pediatric patients. LEVEL OF EVIDENCE: Diagnostic Test/Criteria; Level II.

Implementation of Multimodality Neurologic Monitoring Reporting in Pediatric Traumatic Brain Injury Management.

BACKGROUND/OBJECTIVE: Multimodality neurologic monitoring (MMM) is an emerging technique for management of traumatic brain injury (TBI). An increasing array of MMM-derived biomarkers now exist that are associated with injury severity and functional outcomes after TBI. A standardized MMM reporting process has not been well described, and a paucity of evidence exists relating MMM reporting in TBI management with functional outcomes or adverse events. METHODS: Prospective implementation of standardized MMM reporting at a single pediatric intensive care unit (PICU) is described that included monitoring of intracranial pressure (ICP), cerebral oxygenation and electroencephalography (EEG). The incidence of clinical decisions made using MMM reporting is described, including timing of neuroimaging, ICP monitoring discontinuation, use of paralytic, hyperosmolar and pentobarbital therapies, neurosurgical interventions, ventilator and CPP adjustments and neurologic prognostication discussions. Retrospective analysis was performed on the association of MMM reporting with initial Glasgow Coma Scale (GCS) and Pediatric Risk of Mortality III (PRISM III) scores, duration of total hospitalization and PICU hospitalization, duration of mechanical ventilation and invasive ICP monitoring, inpatient complications, time with ICP > 20 mmHg, time with cerebral perfusion pressure (CPP) < 40 mmHg and 12-month Glasgow Outcome Scale-Extended Pediatrics (GOSE-Peds) scores. Association of outcomes with MMM reporting was investigated using the Wilcoxon rank-sum test or Fisher's exact test, as appropriate. RESULTS: Eighty-five children with TBI underwent MMM over 6 years, among which 18 underwent daily MMM reporting over a 21-month period. Clinical decision-making influenced by MMM reporting included timing of neuroimaging (100.0%), ICP monitoring discontinuation (100.0%), timing of extubation trials of surviving patients (100.0%), body repositioning (11.1%), paralytic therapy (16.7%), hyperosmolar therapy (22.2%), pentobarbital therapy (33.3%), provocative cerebral autoregulation testing (16.7%), adjustments in CPP thresholds (16.7%), adjustments in PaCO2 thresholds (11.1%), neurosurgical interventions (16.7%) and neurologic prognostication discussions (11.1%). The implementation of MMM reporting was associated with a reduction in ICP monitoring duration (p = 0.0017) and mechanical ventilator duration (p = 0.0018). No significant differences were observed in initial GCS or PRISM III scores, total hospitalization length, PICU hospitalization length, total complications, time with ICP > 20 mmHg, time with CPP < 40 mmHg, use of tier 2 therapy, or 12-month GOS-E Peds scores. CONCLUSION: Implementation of MMM reporting in pediatric TBI management is feasible and can be impactful in tailoring clinical decisions. Prospective work is needed to understand the impact of MMM and MMM reporting systems on functional outcomes and clinical care efficacy.

Identifying Maltreatment in Infants and Young Children Presenting With Fractures: Does Age Matter?

OBJECTIVES: Child abuse is a significant cause of morbidity and mortality in preverbal children who cannot explain their injuries. Fractures are among the most common injuries associated with abuse but of themselves fractures may not be recognized as abusive until a comprehensive child abuse evaluation is completed, often prompted by other signs or subjective features. We sought to determine which children presenting with rib or long-bone fractures should undergo a routine abuse evaluation based on age. METHODS: A systematic review searching Ovid, PubMed/Medline, Scopus, and CINAHL from 1980 to 2020 was performed. An evidence-based framework was generated by a consensus panel and applied to the results of the systematic review to form recommendations. Fifteen articles were suitable for final analysis. RESULTS: Studies with comparable age ranges of subjects and sufficient evidence to meet the determination of abuse standard for pediatric patients with rib, humeral, and femoral fractures were identified. Seventy-seven percent of children presenting with rib fractures aged less than 3 years were abused; when those involved in motor vehicle collisions were excluded, 96% were abused. Abuse was identified in 48% of children less than 18 months with humeral fractures. Among those with femoral fractures, abuse was diagnosed in 34% and 25% of children aged less than 12 and 18 months, respectively. CONCLUSION: Among children who were not in an independently verified incident, the authors strongly recommend routine evaluation for child abuse, including specialty child abuse consultation, for: 1) children aged less than 3 years old presenting with rib fractures and 2) children aged less than 18 months presenting with humeral or femoral fractures (Level of Evidence: III Review).

Moving Toward Standardized Pediatric Performance Improvement Measures in Child Physical Abuse: A Modified Delphi Approach.

BACKGROUND: Limited guidance exists for pediatric trauma centers (PTCs) regarding best practice for measuring and reviewing performance improvement (PI) in the child physical abuse population. To move PTC programs toward standardized guidelines and PI practices, current practice and points of consensus among level 1 and 2 PTCs across the United States were assessed. METHODS: Utilizing a two-round, modified Delphi methodology, electronic surveys were distributed to pediatric trauma program managers and coordinators representing 125 PTCs. Survey data included demographics, coding practices, definitions, current PI measures, prevention programs, and opinions regarding key components of child physical abuse guidelines. RESULTS: In Round 1, responses were received from 90 (72%) PTCs [47 (84%) ACS-verified level 1 PTCs; 29 (73%) ACS-verified level 2 PTCs; and 14 (48%) state PTCs]. Of the respondents, 87% agreed that establishing a national consensus for child physical abuse PI is important, and 92% agreed that their institution would benefit from standardized guidelines. Although PI process varied among PTCs in terms of measures, review, and coding practices, several points of consensus were achieved. CONCLUSION: Survey results demonstrate areas of consistency and a foundation for consensus among PTCs. Results also identify areas of practice diversity that may benefit from an attempt to standardize PI across centers.

Inflicted versus unintentional injury: towards improved detection and surveillance of supervisory neglect.

BACKGROUND: Many children evaluated for child abuse have non-inflicted injuries due to supervisory neglect. Despite its prevalence, supervisory neglect has received minimal attention. METHODS: We performed a retrospective review of patients maintained in a hospital forensic registry. Text analytics software was used to classify types of supervisory neglect from reported mechanism of injury (MOI). Logistic regression was used to assess risks associated with supervisory neglect. RESULTS: For 1185 eligible patients, 553 were classified as having unintentional injuries. Text analysis identified four types of supervisory neglect for falls (N = 376): interrupted supervision (53.4%); failure to adapt the home (26.7%); safety equipment non-compliance (12.8%); inadequate substitute care (7.0%); a fifth category was identified for non-falls (N = 54): rough handling (32.0%). Supervisory neglect was associated with MOI consistent with the injury (AOR = 15.5[p < 0.001]), no loss of consciousness (AOR = 6.8(p < 0.001]), no bruising away from the injury site (AOR = 3.7[p < 0.001]), and direct hospital presentation (AOR = 1.8[p < 0.05]). Of the 553 with unintentional injury, 62% had isolated head injuries; 20%, however, had evidence of prior head trauma. CONCLUSIONS: Interrupted supervision was the most common form of supervisory neglect. Twenty percent of forensics patients with head injury found to have non-inflicted injuries had evidence of prior head injury. Supervisory neglect suggests a high-risk population. LEVEL OF EVIDENCE: Level II, Prognosis.

RBC transfusions in children requiring intensive care admission after traumatic injury*.

OBJECTIVE: To describe packed RBC utilization patterns in trauma patients admitted to a PICU and study associated outcomes while controlling for severity. DESIGN: Retrospective cohort study. SETTING: The PICU of a tertiary care children's hospital. PATIENTS: All pediatric trauma patients admitted to Helen DeVos Children's Hospital PICU between June 2007 and July 2010, either directly from the emergency department or transferred from another institution. INTERVENTIONS: None. MEASUREMENTS AND MAIN RESULTS: Of 389 trauma patients, 107 patients (27.5%) transferred to the PICU were transfused with blood products. Of these transfusions, 81 were packed RBC transfusions and 26 were other blood products. Only 73 of the packed RBC transfusions had a documented time of transfusion: 17 (23.3%) were transfused prior to PICU admission, seven (9.5%) both before and after PICU, and 49 (67.1%) only after PICU admission. After adjusting for injury severity score, transfused patients had higher odds of needing mechanical ventilation (odds ratios, 9.2; 95% CI, 3.6-23.3) and higher risk of mortality (odds ratios, 8.6; 95% CI, 2.6-28.6), when compared with nontransfused patients. Mean age of packed RBC was 19.6 ± 9.3 days (mean ± SD). The impact of age of packed RBCs on mortality was examined as a categorical variable at 14, 21, and 28 days. Packed RBCs more than 28 days old (14/61 patients) were associated with longer lengths of stay (13 ± 12 vs 7 ± 6; p < 0.03), lower discharge Glasgow Coma Scale score (9 ± 6 vs 13 ± 4; p< 0.03), and more mortality (43% vs 13%; p < 0.02) when compared with blood less than 28 days old. CONCLUSIONS: In pediatric trauma patients, transfusion of packed RBC and use of older RBC units are associated with higher risk of adverse outcomes independent of injury severity.
