Impact of institutional prophylaxis guidelines on rates of pediatric venous thromboembolism following trauma-A multicenter study from the pediatric trauma society research committee.

BACKGROUND: A paucity of data exists with regard to the incidence, management, and outcomes of venous thromboembolism (VTE) in injured children. We sought to determine the impact of institutional chemoprophylaxis guidelines on VTE rates in a pediatric trauma population. METHODS: A retrospective review of injured children (≤15 years) admitted between 2009 and 2018 at 10 pediatric trauma centers was performed. Data were gathered from institutional trauma registries and dedicated chart review. The institutions were surveyed as to whether they had chemoprophylaxis guidelines in place for high-risk pediatric trauma patients, and outcomes were compared based on the presence of guidelines using χ 2 analysis ( p < 0.05). RESULTS: There were 45,202 patients evaluated during the study period. Three institutions (28,359 patients, 63%) had established chemoprophylaxis policies during the study period ("Guidelines"); the other seven centers (16,843 patients, 37%) had no such guidelines ("Standard"). There were significantly lower rates of VTE in the Guidelines group, but these patients also had significantly fewer risk factors. Among critically injured children with similar clinical presentations, there was no difference in VTE rate. Specifically within the Guidelines group, 30 children developed VTE. The majority (17/30) were actually not indicated for chemoprophylaxis based on institutional guidelines. Still, despite protocols only one VTE patient in the guidelines group who was indicated for intervention ended up receiving chemoprophylaxis prior to diagnosis. No consistent ultrasound screening protocol was in place at any institution during the study. CONCLUSION: The presence of an institutional policy to guide chemoprophylaxis for injured children is associated with a decreased overall frequency of VTE, but this disappears when controlling for patient factors. However, the overall efficacy is impacted by a combination of deficits in guideline compliance and structure. Further prospective data are needed to help determine the ideal role for chemoprophylaxis and protocols in pediatric trauma. LEVEL OF EVIDENCE: Therapeutic/Care Management; Level IV.

Development of the Red Flag Scorecard Screening Tool for Identification of Child Physical Abuse in the Emergency Department.

BACKGROUND: Child physical abuse (CPA) may have subtle presenting signs and can be challenging to identify, especially at emergency centers that do not treat many children. The purpose of this study is to determine the performance of a simple CPA screening tool to identify children most at risk. METHODS: A screening tool ("Red Flag Scorecard") was developed utilizing available evidence-based presenting findings and expert consensus. Retrospective chart review of children treated for injuries between 2014 and 2018 with suspected or confirmed CPA at a level I pediatric trauma center was then performed to validate the screening tool. Descriptive statistics and chi square tests were used to analyze the data. RESULTS: Of 408 cases, median age was 7 months and 60% were male. The majority (69%) were under 1 year of age. The most common history finding was delay in seeking care (58%, 236/408; p = <0.0001), the most common physical exam finding was bruising located away from bony prominences (45%, 182/408), and the most common imaging finding was unexplained brain injury (49%, 201/408). The majority, 84% (343/408), had at least 2 history findings. The combination score of at least 2 history findings and 1 physical/imaging finding was most sensitive (79%). The scorecard would have identified 94% of children who presented with no trauma history (198/211). CONCLUSION: The Red Flag Scorecard may serve as a quick and effective screening tool to raise suspicion for child physical abuse in emergency centers. Prospective study is planned to validate these results. LEVEL OF EVIDENCE: IV.

Pediatric Ingestions.

Pediatric ingestions encompass a wide range of diseases, including foreign body ingestions, caustic ingestions, and aspiration. Specific topics of interest in the pediatric age group for adult general surgeons are button batteries and magnets, which have significant morbidity and mortality and require a high index of suspicion to provide timely care. Evaluation and management of these cases should be tailored to the offending agent and managed at an appropriate pediatric center.

Pediatric Mild Traumatic Brain Injury: Who Can Be Managed at a Non-pediatric Trauma Center Hospital? A Systematic Review of the Literature.

BACKGROUND: Pediatric traumatic brain injury (TBI) affects about 475,000 children in the United States annually. Studies from the 1990s showed worse mortality in pediatric TBI patients not transferred to a pediatric trauma center (PTC), but did not examine mild pediatric TBI. Evidence-based guidelines used to identify children with clinically insignificant TBI who do not require head CT were developed by the Pediatric Emergency Care Applied Research Network (PECARN). However, which patients can be safely observed at a non-PTC is not directly addressed. METHODS: A systematic review of the literature was conducted, focusing on management of pediatric TBI and transfer decisions from 1990 to 2020. RESULTS: Pediatric TBI patients make up a great majority of preventable transfers and admissions, and comprise a significant portion of avoidable costs to the health care system. Majority of mild TBI patients admitted to a PTC following transfer do not require ICU care, surgical intervention, or additional imaging. Studies have shown that as high as 83% of mild pediatric TBI patients are discharged within 24 hrs. CONCLUSIONS: An evidence-based clinical practice algorithm was derived through synthesis of the data reviewed to guide transfer decision. The papers discussed in our systematic review largely concluded that transfer and admission was unnecessary and costly in pediatric patients with mild TBI who met the following criteria: blunt, no concern for NAT, low risk on PECARN assessment, or intermediate risk on PECARN with negative imaging or imaging with either isolated, nondisplaced skull fractures without ICH and/or EDH, or SDH <0.3 cm with no midline shift.

Venous thromboembolic risk stratification in pediatric trauma: A Pediatric Trauma Society Research Committee multicenter analysis.

BACKGROUND: Venous thromboembolism (VTE) in injured children is rare, but its consequences are significant. Several risk stratification algorithms for VTE in pediatric trauma exist with little consensus, and all are hindered in development by relying on registry data with known inaccuracies. We performed a multicenter review to evaluate trauma registry fidelity and confirm the effectiveness of one established algorithm across diverse centers. METHODS: Local trauma registries at 10 institutions were queried for all patients younger than 18 years admitted between 2009 and 2018. Additional chart review was performed on all "VTE" cases and random non-VTE controls to assess registry errors. Corrected data were then applied to our prediction algorithm using 10 real-time variables (Glasgow Coma Scale, age, sex, intensive care unit admission, transfusion, central line placement, lower extremity/pelvic fracture, major surgery) to calculate VTE risk scores. Contingency table classifiers and the area under a receiver operator characteristic curve were calculated. RESULTS: Registries identified 52,524 pediatric trauma patients with 99 episodes of VTE; however, chart review found that 13 cases were misclassified for a corrected total of 86 cases (0.16%). After correction, the algorithm still displayed strong performance in discriminating VTE-fated encounters (sensitivity, 69%; area under the receiver operating characteristic curve, 0.96). Furthermore, despite wide institutional variability in VTE rates (0.04-1.7%), the algorithm maintained a specificity of >91% and a negative predictive value of >99.7% across centers. Chart review also revealed that 54% (n = 45) of VTEs were directly associated with a central line, usually femoral (n = 34, p < 0.001 compared with upper extremity), and that prophylaxis rates were underreported in the registries by about 50%; still, only 19% of the VTE cases had been on prophylaxis before diagnosis. CONCLUSION: The VTE prediction algorithm performed well when applied retrospectively across 10 diverse pediatric centers using corrected registry data. These findings can advance initiatives for VTE screening/prophylaxis guidance following pediatric trauma and warrant prospective study.

Addition of neurological status to pediatric adjusted shock index to predict early mortality in trauma: A pediatric Trauma Quality Improvement Program analysis.

INTRODUCTION: Pediatric adjusted shock index (SIPA) has demonstrated the ability to prospectively identify children at the highest risk for early mortality. The addition of neurological status to shock index has shown promise as a reliable triage tool in adult trauma populations. This study sought to assess the utility of combining SIPA with Glasgow Coma Scale (GCS) for predicting early trauma-related outcomes. METHODS: Retrospective review of the 2017 Trauma Quality Improvement Program Database was performed for all severely injured patients younger than 18 years old. Pediatric adjusted shock index and reverse SIPA × GCS (rSIG) were calculated. Age-specific cutoff values were derived for reverse shock index multiplied by GCS (rSIG) and compared with their SIPA counterparts for early mortality assessment using area under the receiver operating characteristic curve analyses. RESULTS: A total of 10,389 pediatric patients with an average age of 11.4 years, 67% male, average Injury Severity Score of 24.1, and 4% sustaining a major penetrating injury were included in the analysis. The overall mortality was 9.3%. Furthermore, 32.1% of patients displayed an elevated SIPA score, while only 27.5% displayed a positive rSIG. On area under the receiver operating characteristic curve analysis, rSIG was found to be superior to SIPA as a predictor for in hospital mortality with values of 0.854 versus 0.628, respectively. CONCLUSION: Reverse shock index multiplied by GCS more readily predicted in hospital mortality for pediatric trauma patients when compared with SIPA. These findings suggest that neurological status should be an important factor during initial patient assessment. Further study to assess the applicability of rSIG for expanded trauma-related outcomes in pediatric trauma is necessary. LEVEL OF EVIDENCE: Prognostic study, level IV.

Contemporary management of pediatric open skull fractures: a multicenter pediatric trauma center study.

OBJECTIVE: The authors sought to evaluate the contemporary management of pediatric open skull fractures and assess the impact of variations in antibiotic and operative management on the incidence of infectious complications. METHODS: The records of children who presented from 2009 to 2017 to 6 pediatric trauma centers with an open calvarial skull fracture were reviewed. Data collected included mechanism and anatomical site of injury; presence and depth of fracture depression; antibiotic choice, route, and duration; operative management; and infectious complications. RESULTS: Of the fractures among the 138 patients included in the study, 48.6% were frontal and 80.4% were depressed; 58.7% of patients underwent fragment elevation. The average duration of intravenous antibiotics was 4.6 (range 0-21) days. Only 53 patients (38.4%) received a single intravenous antibiotic for fewer than 4 days. and 56 (40.6%) received oral antibiotics for an average of 7.3 (range 1-20) days. Wounds were managed exclusively in the emergency department in 28.3% of patients. Two children had infectious complications, including a late-presenting hardware infection and a superficial wound infection. There were no cases of meningitis or intracranial abscess. Neither antibiotic spectrum or duration nor bedside irrigation was associated with the development of infection. CONCLUSIONS: The incidence of infectious complications in this population of children with open skull fractures was low and was not associated with the antibiotic strategy or site of wound care. Most minimally contaminated open skull fractures are probably best managed with a short duration of a single antibiotic, and emergency department closure is appropriate unless there is significant contamination or fragment elevation is necessary.

Pediatric adjusted reverse shock index multiplied by Glasgow Coma Scale as a prospective predictor for mortality in pediatric trauma.

INTRODUCTION: Shock index and its pediatric adjusted derivative (pediatric age-adjusted shock index [SIPA]) have demonstrated utility as prospective predictors of mortality in adult and pediatric trauma populations. Although basic vital signs provide promise as triage tools, factors such as neurologic status on arrival have profound implications for trauma-related outcomes. Recently, the reverse shock index multiplied by Glasgow Coma Scale (GCS) score (rSIG) has been validated in adult trauma as a tool combining early markers of physiology and neurologic function to predict mortality. This study sought to compare the performance characteristics of rSIG against SIPA as a prospective predictor of mortality in pediatric war zone injuries. METHODS: Retrospective review of the Department of Defense Trauma Registry, 2008 to 2016, was performed for all patients younger than 18 years with documented vital signs and GCS on initial arrival to the trauma bay. Optimal age-specific cutoff values were derived for rSIG via the Youden index using receiver operating characteristic analyses. Multivariate logistic regression was performed to validate accuracy in predicting early mortality. RESULTS: A total of 2,007 pediatric patients with a median age range of 7 to 12 years, 79% male, average Injury Severity Score of 11.9, and 62.5% sustaining a penetrating injury were included in the analysis. The overall mortality was 7.1%. A total of 874 (43.5%) and 685 patients (34.1%) had elevated SIPA and pediatric rSIG scores, respectively. After adjusting for demographics, mechanism of injury, initial vital signs, and presenting laboratory values, rSIG (odds ratio, 4.054; p = 0.01) was found to be superior to SIPA (odds ratio, 2.742; p < 0.01) as an independent predictor of early mortality. CONCLUSION: Reverse shock index multiplied by GCS score more accurately identifies pediatric patients at highest risk of death when compared with SIPA alone, following war zone injuries. These findings may help further refine early risk assessments for patient management and resource allocation in constrained settings. Further validation is necessary to determine applicability to the civilian population. LEVEL OF EVIDENCE: Prognostic study, level IV.

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).

A simple technique for neoumbilical reconstruction for congenital hernia associated proboscis deformity.

INTRODUCTION: Umbilical reconstruction in pediatric patients who have developed a large proboscoid redundancy can be challenging after standard umbilical repair. We present a simple and unique surgical technique that results in a cosmetically appealing reconstruction. OPERATIVE TECHNIQUE: The operation is initiated with circumferential redundant skin excision and isolation of the hernia sac. Primary fascial repair is performed. Reconstruction utilizes the cut dermal/epidermal edge by approximating it to the exposed fascia just below the skin edge outside of the fascial repair in a purse string fashion for the creation of a neoumbilicus. CONCLUSION: This simple technique is unique from any currently published methods and results in a cosmetically pleasing reconstruction without evidence of any incision. LEVEL OF EVIDENCE: Level V: Expert Opinion.

Predictors of Bowel Resection During Nonelective Ladd Procedure for Pediatric Malrotation.

BACKGROUND: The objective of this study was to identify risk factors for bowel resection in a modern cohort of patients undergoing nonelective Ladd procedures. MATERIALS AND METHODS: Retrospective descriptive analysis of patients with Ladd procedure (CPT 44055) in the National Surgical Quality Improvement Program-Pediatric (NSQIP-P) database (2012-2015). Exclusion criteria were elective case, duodenal atresia, or other known congenital anomaly (except cardiac, structural central nervous system, or airway anomaly) and open wounds from prior surgery or drains. Independent variables included all preoperative variables within NSQIP-P. The primary outcome variable was bowel resection as a concurrent procedure. Multivariate analysis was performed by incorporating all independent variables into a stepwise forward logistic regression model to identify independent risk factors for bowel resection. RESULTS: Of 267,289 patients in NSQIP-P, 1284 had a Ladd procedure. Of these, 292 were performed urgently or emergently in children with no known atresias, congenital anomalies, or open wounds. Twenty-nine (10%) had a bowel resection. On univariate analysis, bowel resection rates did not differ by age, weight, prematurity, ventilator dependence, asthma, chronic lung disease, tracheostomy, esophageal or gastrointestinal disease, hepatobiliary or pancreatic disease, cerebral palsy, central nervous system abnormality, neuromuscular disorder, intraventricular hemorrhage, steroid use, hematologic disorder, malignancy, sepsis, inotropic support, or CPR (P = nonsignificant). Higher rates of bowel resection were observed in patients with cardiac risk factors, white blood count (WBC) >15K, oxygen support, nutritional support, and developmental delay (P < 0.05). Only cardiac risk factors and WBC >15K were significant on multivariate analysis. CONCLUSIONS: Bowel resections (10% in this cohort of nonelective Ladd procedures) were independently associated with cardiac risk factors and WBC >15K. LEVEL OF EVIDENCE: III.

Management and outcomes of peripancreatic fluid collections and pseudocysts following non-operative management of pancreatic injuries in children.

BACKGROUND: Peripancreatic fluid collection and pseudocyst development is a common sequela following non-operative management (NOM) of pancreatic injuries in children. Our purpose was to review management strategies and assess outcomes. METHODS: A multicenter, retrospective review was conducted of children treated with NOM following blunt pancreatic injury at 22 pediatric trauma centers between the years 2010 and 2015. Organized fluid collections were called "acute peripancreatic fluid collection" (APFC) if identified < 4 weeks and "pseudocyst" if > 4 weeks following injury. Data analysis included descriptive statistics Wilcoxon rank-sum, Kruskal-Wallis and t tests. RESULTS: One hundred patients with blunt pancreatic injury were identified. Median age was 8.5 years (range 1-16). Forty-two percent of patients (42/100) developed organized fluid collections: APFC 64% (27/42) and pseudocysts 36% (15/42). Median time to identification was 12 days (range 7-42). Most collections (64%, 27/42) were observed and 36% (15/42) underwent drainage: 67% (10/15) percutaneous drain, 7% (1/15) needle aspiration, and 27% (4/15) endoscopic transpapillary stent. A definitive procedure (cystogastrostomy/pancreatectomy) was required in 26% (11/42). Patients with larger collections (≥ 7.1 cm) had longer time to resolution. Comparison of outcomes in patients with observation vs drainage revealed no significant differences in TPN use (79% vs 75%, p = 1.00), hospital length of stay (15 vs 25 median days, p = 0.11), time to tolerate regular diet (12 vs 11 median days, p = 0.47), or need for definitive procedure (failure rate 30% vs 20%, p = 0.75). CONCLUSIONS: Following NOM of blunt pancreatic injuries in children, organized fluid collections commonly develop. If discovered early, most can be observed successfully, and drainage does not appear to improve clinical outcomes. Larger size predicts prolonged recovery. LEVEL OF EVIDENCE: III STUDY TYPE: Case series.

Child abuse and the pediatric surgeon: A position statement from the Trauma Committee, the Board of Governors and the Membership of the American Pediatric Surgical Association.

BACKGROUND: The pediatric surgeon is in a unique position to assess, stabilize, and manage a victim of child physical abuse (formerly nonaccidental trauma [NAT]) in the setting of a formal trauma system. METHODS: The American Pediatric Surgical Association (APSA) endorses the concept of child physical abuse as a traumatic disease that justifies the resource utilization of a trauma system to appropriately evaluate and manage this patient population including evaluation by pediatric surgeons. RESULTS: APSA recommends the implementation of a standardized tool to screen for child physical abuse at all state designated trauma or ACS verified trauma and children's surgery hospitals. APSA encourages the admission of a suspected child abuse patient to a surgical trauma service because of the potential for polytrauma and increased severity of injury and to provide reliable coordination of services. Nevertheless, APSA recognizes the need for pediatric surgeons to participate in a multidisciplinary team including child abuse pediatricians, social work, and Child Protective Services (CPS) to coordinate the screening, evaluation, and management of patients with suspected child physical abuse. Finally, APSA recognizes that if a pediatric surgeon suspects abuse, a report to CPS for further investigation is mandated by law. CONCLUSION: APSA supports data accrual on abuse screening and diagnosis into a trauma registry, the NTDB and the Pediatric ACS TQIP® for benchmarking purposes and quality improvement.

Long-term sustainability of Washington State's quality improvement initiative for the management of pediatric spleen injuries.

BACKGROUND: Initial results of Washington State's quality improvement initiative addressing the management of blunt traumatic pediatric spleen injuries were published in 2008. In this update, we evaluated whether these effects were sustained over time. METHODS: Data from the Washington Trauma Registry for years 1999-2001 (pre-intervention), 2003-2005 (post-intervention), and 2012-2014 (follow-up) were used in a retrospective cohort study. Children between ages 0 to 14 years who were hospitalized with a traumatic blunt spleen injury were included. Multivariable logistic regression was used to account for patient, injury, and hospital characteristics. RESULTS: Overall, splenectomies continued to be less common with 8.3% of pediatric patients receiving splenectomies in the follow-up period compared with 14.3% and 7.2% in the preintervention and post-intervention periods (p = 0.034). After adjustment, splenectomies remained less likely to be performed in both post-intervention (OR = 0.37; 95% CI = 0.16-0.90) and follow-up periods (OR = 0.29; 95% CI = 0.12-0.70) compared to pre-intervention. Children were much more likely to be cared for at pediatric trauma hospitals in the follow-up period (OR = 5.13; 95% CI = 2.79-9.43) after adjustment. CONCLUSIONS: Evaluation of this statewide quality improvement initiative showed that positive changes in management practices persist. This evidence suggests that statewide quality improvement initiatives can be sustainable with minimal ongoing effort. LEVEL OF EVIDENCE: Level III.

Impact on Hospital Resources of Systematic Evaluation and Management of Suspected Nonaccidental Trauma in Patients Less Than 4 Years of Age.

OBJECTIVE: There has been an increasing movement worldwide to create systematic screening and management procedures for atypical injury patterns in children with the hope of better detecting and evaluating nonaccidental trauma (NAT). A legitimate concern for any hospital considering implementation of a systematic evaluation process is the impact on already burdened hospital resources. We hypothesized that implementation of a guideline that uses red flags related to history, physical, or radiologic findings to trigger a standardized NAT evaluation of patients <4 years would not negatively affect resource utilization at our level II pediatric trauma center. METHODS: NAT cases were evaluated retrospectively before and prospectively after implementation of the NAT guideline (n = 117 cases before implementation, n = 72 cases postimplementation). Multiple linear and logistic regression, χ2, and Wilcoxon rank-sum tests were used to evaluate human, laboratory, technology, and hospital resource usage between cohorts. RESULTS: Human (child abuse intervention department, ophthalmology, and evaluation by a pediatric surgeon for admitted patients), laboratory (urine toxicology and liver function tests), and imaging (skeletal survey and head or abdominal computed tomography) resource use did not differ significantly between cohorts (all P > .05). Emergency department and hospital lengths of stays also did not differ between cohorts. A significant 13% decrease in the percentage of patients admitted to the hospital was observed (P = .01). CONCLUSIONS: Structured evaluation and management of pediatric patients with injuries atypical for their age does not confer an added burden on hospital resources and may reduce the percentage of such patients who are hospitalized.

Complications in neonatal surgery.

Neonatal surgery is recognized as an independent discipline in general surgery, requiring the expertise of pediatric surgeons to optimize outcomes in infants with surgical conditions. Survival following neonatal surgery has improved dramatically in the past 60 years. Improvements in pediatric surgical outcomes are in part attributable to improved understanding of neonatal physiology, specialized pediatric anesthesia, neonatal critical care including sophisticated cardiopulmonary support, utilization of parenteral nutrition and adjustments in fluid management, refinement of surgical technique, and advances in surgical technology including minimally invasive options. Nevertheless, short and long-term complications following neonatal surgery continue to have profound and sometimes lasting effects on individual patients, families, and society.
