Abstract
INTRODUCTION Some studies in both children and adults have shown a mortality benefit for the use of low titer group O whole blood (LTOWB) compared to component therapy for traumatic resuscitation. Although LTOWB is not widely available at pediatric trauma centers, its use is increasing. We hypothesized that in children who received whole blood after injury, the proportion of whole blood in relation to the total blood product resuscitation volume would impact survival. METHODS The trauma database from a single academic pediatric level 1 trauma center was queried for pediatric (age < 18 years) recipients of LTOWB after injury (years 2015-2022). Weight-based blood product (LTOWB, red blood cells, plasma and platelet) transfusion volumes during the first 24 hours of admission were recorded. The ratio of LTOWB to total transfusion volume was calculated. The primary outcome was in-hospital mortality. Multivariable logistic regression model adjusted for the following variables: age, sex, mechanism of injury, injury severity score, shock index, and Glasgow Coma Scale (GCS) score. Adjusted odds ratio representing the change in the odds of mortality by a 10% increase in the LTOWB:total transfusion volume ratio was reported. RESULTS There were 95 pediatric LTOWB recipients included in the analysis, with median (IQR) age of 10 years (5-14), 58% male, median (IQR) injury severity score of 26 (17-35), 25% penetrating mechanism. The median(IQR) volume of LTOWB transfused was 17 (15-35) mL/kg. LTOWB comprised a median (IQR) of 59% (33-100) of the total blood product resuscitation. Among patients who received LTOWB, there was a 38% decrease in in-hospital mortality for each 10% increase in the proportion of WB within total transfusion volume (p < 0.001) after adjusting for age, sex, mechanism of injury, injury severity score, shock index, and GCS score. CONCLUSION Increased proportions of LTOWB within the total blood product resuscitation was independently associated with survival in injured children. Based on existing data that suggests safety and improved outcomes with whole blood, consideration may be given to increasing the use of LTOWB over CT resuscitation in pediatric trauma resuscitation.

Abstract
INTRODUCTION Admission hypocalcemia has been associated with poor outcomes in injured adults. The impact of hypocalcemia on mortality has not been widely studied in pediatric trauma. METHODS A pediatric trauma center database was queried retrospectively (2013-2022) for children age < 18 years who received blood transfusion within 24 hours of injury and had ionized calcium (iCal) level on admission. Children who received massive transfusion (>40 mL/kg) prior to hospital arrival or calcium prior to laboratory testing were excluded. Hypocalcemia was defined by the laboratory lower limit (iCal <1.00). Main outcomes were in-hospital mortality and 24-hour blood product requirements. Logistic regression analysis was performed to adjust for injury severity score (ISS), admission shock index, Glasgow Coma Score (GCS) and weight-adjusted total transfusion volume. RESULTS In total, 331 children with median (IQR) age of 7 years (2-13) and median (IQR) ISS 25 (14-33) were included, 32 (10%) of whom were hypocalcemic on arrival to the hospital. The hypocalcemic cohort had higher ISS (median (IQR) 30(24-36) vs 22(13-30)) and lower admission GCS (median (IQR) 3 (3-12) vs 8 (3-15)). Age, sex, race, and mechanism were not significantly different between groups. On univariate analysis, hypocalcemia was associated with increased in-hospital (56% vs 18%; p < 0.001) and 24-hour (28% vs 5%; p < 0.001) mortality. Children who were hypocalcemic received a median (IQR) of 22 mL/kg (7-38) more in total weight-adjusted 24-hour blood product transfusion following admission compared to the normocalcemic cohort (p = 0.005). After adjusting for ISS, shock index, GCS, and total transfusion volume, hypocalcemia remained independently associated with increased 24-hour (Odds Ratio(OR) 95% Confidence Interval(CI) = 4.93(1.77-13.77); p = 0.002) and in-hospital mortality (OR 95% CI =3.41(1.22-9.51); p = 0.019). CONCLUSION Hypocalcemia is independently associated with mortality and receipt of greater weight-adjusted volumes of blood product transfusion after injury in children. The benefit of timely calcium administration in pediatric trauma needs further exploration. LEVEL OF EVIDENCE III; prognostic/epidemiological.

New Functional Impairment After Hospital Discharge by Traumatic Brain Injury Mechanism in Younger Than 3 Years Old Admitted to the PICU in a Single Center Retrospective Study. Pediatr Crit Care Med 2024; 25:250-258.

Abstract
OBJECTIVES Children who suffer traumatic brain injury (TBI) are at high risk of morbidity and mortality. We hypothesized that in patients with TBI, the abusive head trauma (AHT) mechanism vs. accidental TBI (aTBI) would be associated with higher frequency of new functional impairment between baseline and later follow-up. DESIGN Retrospective single center cohort study. SETTING AND PATIENTS Children younger than 3 years old admitted with TBI to the PICU at a level 1 trauma center between 2014 and 2019. INTERVENTIONS None. MEASUREMENTS AND MAIN RESULTS Patient characteristics, TBI mechanism, and Functional Status Scale (FSS) scores at baseline, hospital discharge, short-term (median, 10 mo [interquartile range 3-12 mo]), and long-term (median, 4 yr [3-6 yr]) postdischarge were abstracted from the electronic health record. New impairment was defined as an increase in FSS greater than 1 from baseline. Patients who died were assigned the highest score (30). Multivariable logistic regression was performed to determine the association between TBI mechanism with new impairment. Over 6 years, there were 460 TBI children (170 AHT, 290 aTBI), of which 13 with AHT and four with aTBI died. Frequency of new impairment by follow-up interval, in AHT vs. aTBI patients, were as follows: hospital discharge (42/157 [27%] vs. 27/286 [9%]; p < 0.001), short-term (42/153 [27%] vs. 26/259 [10%]; p < 0.001), and long-term (32/114 [28%] vs. 18/178 [10%]; p < 0.001). Sensory, communication, and motor domains were worse in AHT patients at the short- and long-term timepoint. On multivariable analysis, AHT mechanism was associated with greater odds (odds ratio [95% CI]) of poor outcome (death and new impairment) at hospital discharge (4.4 [2.2-8.9]), short-term (2.7 [1.5-4.9]), and long-term timepoints (2.4 [1.2-4.8]; p < 0.05). CONCLUSIONS In patients younger than 3 years old admitted to the PICU after TBI, the AHT mechanism-vs. aTBI-is associated with greater odds of poor outcome in the follow-up period through to ~5 years postdischarge. New impairment occurred in multiple domains and only AHT patients further declined in FSS over time.

Use of whole blood in pediatric trauma: a narrative review. Trauma Surg Acute Care Open 2024; 9:e001127. [PMID: 38196932 PMCID: PMC10773435 DOI: 10.1136/tsaco-2023-001127] [Citation(s) in RCA: 1] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/13/2023] [Accepted: 10/03/2023] [Indexed: 01/11/2024] Open
Abstract
Balanced hemostatic resuscitation has been associated with improved outcomes in patients with both pediatric and adult trauma. Cold-stored, low-titer group O whole blood (LTOWB) has been increasingly used as a primary resuscitation product in trauma in recent years. Benefits of LTOWB include rapid, balanced resuscitation in one product, platelets stored at 4°C, fewer additives and fewer donor exposures. The major theoretical risk of LTOWB transfusion is hemolysis, however this has not been shown in the literature. LTOWB use in injured pediatric populations is increasing but is not yet widespread. Seven studies to date have described the use of LTOWB in pediatric trauma cohorts. Safety of LTOWB use in both group O and non-group O pediatric patients has been shown in several studies, as indicated by the absence of hemolysis and acute transfusion reactions, and comparable risk of organ failure. Reported benefits of LTOWB included faster resolution of shock and coagulopathy, lower volumes of transfused blood products, and an independent association with increased survival in massively transfused patients. Overall, pediatric data are limited by small sample sizes and mostly single center cohorts. Multicenter randomized controlled trials are needed.

Multiorgan Dysfunction Syndrome in Abusive and Accidental Pediatric Traumatic Brain Injury. Neurocrit Care 2023:10.1007/s12028-023-01887-y. [PMID: 38062303 DOI: 10.1007/s12028-023-01887-y] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/05/2023] [Accepted: 10/27/2023] [Indexed: 01/05/2024]
Abstract
BACKGROUND Abusive head trauma (AHT) is a mechanism of pediatric traumatic brain injury (TBI) with high morbidity and mortality. Multiorgan dysfunction syndrome (MODS), defined as organ dysfunction in two or more organ systems, is also associated with morbidity and mortality in critically ill children. Our objective was to compare the frequency of MODS and evaluate its association with outcome between AHT and accidental TBI (aTBI). METHODS This was a single center, retrospective cohort study including children under 3 years old admitted to the pediatric intensive care unit with nonpenetrating TBI between 2014 and 2021. Presence or absence of MODS on days 1, 3, and 7 using the Pediatric Logistic Organ Dysfunction-2 score and new impairment status (Functional Status Scale score change > 1 compared with preinjury) at hospital discharge (HD), short-term timepoint, and long-term timepoint were abstracted from the electronic health record. Multiple logistic regression was performed to examine the association between MODS and TBI mechanism with new impairment status. RESULTS Among 576 children, 215 (37%) had AHT and 361 (63%) had aTBI. More children with AHT had MODS on days 1 (34% vs. 23%, p = 0.003), 3 (28% vs. 6%, p < 0.001), and 7 (17% vs. 3%, p < 0.001) compared with those with aTBI. The most common organ failures were cardiovascular ([AHT] 66% vs. [aTBI] 66%, p = 0.997), neurologic (33% vs. 16%, p < 0.001), and respiratory (34% vs. 15%, p < 0.001). MODS was associated with new impairment in multivariable logistic regression at HD (odds ratio 19.1 [95% confidence interval 9.8-38.6, p < 0.001]), short-term discharge (7.4 [3.7-15.2, p < 0.001]), and long-term discharge (4.3 [2.0-9.4, p < 0.001])]. AHT was also associated with new impairment at HD (3.4 [1.6-7.3, p = 0.001]), short-term discharge (2.5 [1.3-4.7, p = 0.005]), and long-term discharge (2.1 [1.1-4.1, p = 0.036]). CONCLUSIONS Abusive head trauma as a mechanism was associated with MODS following TBI. Both AHT mechanism and MODS were associated with new impairment at all time points.

Abstract
BACKGROUND The role of age in mediating coagulation characteristics in injured children is not well defined. We hypothesize thromboelastography (TEG) profiles are unique across pediatric age groups. METHODS Consecutive trauma patients younger than 18 years from a Level I pediatric trauma center database from 2016 to 2020 with TEG obtained on arrival to the trauma bay were identified. Children were categorized by age according to the National Institute of Child Health and Human Development categories (infant, ≤1 year; toddler, 1-2 years; early childhood, 3-5 years; older childhood, 6-11 years; adolescent, 12-17 years). Thromboelastography values were compared across age groups using Kruskal-Wallis and Dunn's tests. Analysis of covariance was performed controlling for sex, Injury Severity Score (ISS), arrival Glasgow Coma Scale (GCS) score, shock, and mechanism of injury. RESULTS In total, 726 subjects were identified; 69% male, median (interquartile range [IQR]) ISS = 12 (5-25), and 83% had a blunt mechanism. On univariate analysis, there were significant differences in TEG α-angle ( p < 0.001), MA ( p = 0.004), and fibrinolysis 30 minutes after MA (LY30) ( p = 0.01) between groups. In post hoc tests, the infant group had significantly greater α-angle (median, 77; IQR, 71-79) and MA (median, 64; IQR, 59-70) compared with other groups, while the adolescent group had significantly lower α-angle (median, 71; IQR, 67-74), MA (median, 60; IQR, 56-64), and LY30 (median, 0.8; IQR, 0.2-1.9) compared with other groups. There were no significant differences between toddler, early childhood, and middle childhood groups. On multivariate analysis, the relationship between age group and TEG values (α-angle, MA, and LY30) persisted after controlling for sex, ISS, GCS, shock, and mechanism of injury. CONCLUSION Age-associated differences in TEG profiles across pediatric age groups exist. Further pediatric-specific research is required to assess whether the unique profiles at extremes of childhood translate to differential clinical outcomes or responses to therapies in injured children.

Pediatric Cervical Spine Injury Following Blunt Trauma in Children Younger Than 3 Years: The PEDSPINE II Study. JAMA Surg 2023; 158:1126-1132. [PMID: 37703025 PMCID: PMC10500431 DOI: 10.1001/jamasurg.2023.4213] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/11/2023] [Accepted: 06/16/2023] [Indexed: 09/14/2023]
Abstract
Importance There is variability in practice and imaging usage to diagnose cervical spine injury (CSI) following blunt trauma in pediatric patients. Objective To develop a prediction model to guide imaging usage and to identify trends in imaging and to evaluate the PEDSPINE model. Design, Setting, and Participants This cohort study included pediatric patients (<3 years years) following blunt trauma between January 2007 and July 2017. Of 22 centers in PEDSPINE, 15 centers, comprising level 1 and 2 stand-alone pediatric hospitals, level 1 and 2 pediatric hospitals within an adult hospital, and level 1 adult hospitals, were included. Patients who died prior to obtaining cervical spine imaging were excluded. Descriptive analysis was performed to describe the population, use of imaging, and injury patterns. PEDSPINE model validation was performed. A new algorithm was derived using clinical criteria and formulation of a multiclass classification problem. Analysis took place from January to October 2022. Exposure Blunt trauma. Main Outcomes and Measures Primary outcome was CSI. The primary and secondary objectives were predetermined. Results The current study, PEDSPINE II, included 9389 patients, of which 128 (1.36%) had CSI, twice the rate in PEDSPINE (0.66%). The mean (SD) age was 1.3 (0.9) years; and 70 patients (54.7%) were male. Overall, 7113 children (80%) underwent cervical spine imaging, compared with 7882 (63%) in PEDSPINE. Several candidate models were fitted for the multiclass classification problem. After comparative analysis, the multinomial regression model was chosen with one-vs-rest area under the curve (AUC) of 0.903 (95% CI, 0.836-0.943) and was able to discriminate between bony and ligamentous injury. PEDSPINE and PEDSPINE II models' ability to identify CSI were compared. In predicting the presence of any injury, PEDSPINE II obtained a one-vs-rest AUC of 0.885 (95% CI, 0.804-0.934), outperforming the PEDSPINE score (AUC, 0.845; 95% CI, 0.769-0.915). Conclusion and Relevance This study found wide clinical variability in the evaluation of pediatric trauma patients with increased use of cervical spine imaging. This has implications of increased cost, increased radiation exposure, and a potential for overdiagnosis. This prediction tool could help to decrease the use of imaging, aid in clinical decision-making, and decrease hospital resource use and cost.

Abstract
Importance Optimal hemostatic resuscitation in pediatric trauma is not well defined. Objective To assess the association of prehospital blood transfusion (PHT) with outcomes in injured children. Design, Setting, and Participants This retrospective cohort study of the Pennsylvania Trauma Systems Foundation database included children aged 0 to 17 years old who received a PHT or emergency department blood transfusion (EDT) from January 2009 and December 2019. Interfacility transfers and isolated burn mechanism were excluded. Analysis took place between November 2022 and January 2023. Exposure Receipt of a blood product transfusion in the prehospital setting compared with the emergency department. Main Outcomes and Measures The primary outcome was 24-hour mortality. A 3:1 propensity score match was developed balancing for age, injury mechanism, shock index, and prehospital Glasgow Comma Scale score. A mixed-effects logistic regression was performed in the matched cohort further accounting for patient sex, Injury Severity Score, insurance status, and potential center-level heterogeneity. Secondary outcomes included in-hospital mortality and complications. Results Of 559 children included, 70 (13%) received prehospital transfusions. In the unmatched cohort, the PHT and EDT groups had comparable age (median [IQR], 47 [9-16] vs 14 [9-17] years), sex (46 [66%] vs 337 [69%] were male), and insurance status (42 [60%] vs 245 [50%]). The PHT group had higher rates of shock (39 [55%] vs 204 [42%]) and blunt trauma mechanism (57 [81%] vs 277 [57%]) and lower median (IQR) Injury Severity Score (14 [5-29] vs 25 [16-36]). Propensity matching resulted in a weighted cohort of 207 children, including 68 of 70 recipients of PHT, and produced well-balanced groups. Both 24-hour (11 [16%] vs 38 [27%]) and in-hospital mortality (14 [21%] vs 44 [32%]) were lower in the PHT cohort compared with the EDT cohort, respectively; there was no difference in in-hospital complications. Mixed-effects logistic regression in the postmatched group adjusting for the confounders listed above found PHT was associated with a significant reduction in 24-hour (adjusted odds ratio, 0.46; 95% CI, 0.23-0.91) and in-hospital mortality (adjusted odds ratio, 0.51; 95% CI, 0.27-0.97) compared with EDT. The number needed to transfuse in the prehospital setting to save 1 child's life was 5 (95% CI, 3-10). Conclusions and Relevance In this study, prehospital transfusion was associated with lower rates of mortality compared with transfusion on arrival to the emergency department, suggesting bleeding pediatric patients may benefit from early hemostatic resuscitation. Further prospective studies are warranted. Although the logistics of prehospital blood product programs are complex, strategies to shift hemostatic resuscitation toward the immediate postinjury period should be pursued.

Abstract
OBJECTIVE The aim of this study was to assess the survival impact of low-titer group O whole blood (LTOWB) in injured pediatric patients who require massive transfusion. SUMMARY BACKGROUND DATA Limited data are available regarding the effectiveness of LTOWB in pediatric trauma. METHODS A prospective observational study of children requiring massive transfusion after injury at UPMC Children's Hospital of Pittsburgh, an urban academic pediatric Level 1 trauma center. Injured children ages 1 to 17 years who received a total of >40 mL/kg of LTOWB and/or conventional components over the 24 hours after admission were included. Patient characteristics, blood product utilization and clinical outcomes were analyzed using Kaplan-Meier survival curves, log rank tests and Cox proportional hazards regression analyses. The primary outcome was 28-day survival. RESULTS Of patients analyzed, 27 of 80 (33%) received LTOWB as part of their hemostatic resuscitation. The LTOWB group was comparable to the component therapy group on baseline demographic and physiologic parameters except older age, higher body weight, and lower red blood cell and plasma transfusion volumes. After adjusting for age, total blood product volume transfused in 24 hours, admission base deficit, international normalized ratio (INR), and injury severity score (ISS), children who received LTOWB as part of their resuscitation had significantly improved survival at both 72 hours and 28 days post-trauma [adjusted odds ratio (AOR) 0.23, P = 0.009 and AOR 0.41, P = 0.02, respectively]; 6-hour survival was not statistically significant (AOR = 0.51, P = 0.30). Survivors at 28 days in the LTOWB group had reduced hospital LOS, ICU LOS, and ventilator days compared to the CT group. CONCLUSION Administration of LTOWB during the hemostatic resuscitation of injured children requiring massive transfusion was independently associated with improved 72-hour and 28-day survival.

Abstract
OBJECTIVE The safety of Low Titer Group O Whole Blood (LTOWB) transfusion has not been well-studied in small children. METHODS This is a single-center retrospective cohort study of pediatric recipients of RhD-LTOWB (June 2016-October 2022) who weigh less than 20 kilograms. Biochemical markers of hemolysis (lactate dehydrogenase, total bilirubin, haptoglobin, and reticulocyte count) and renal function (creatinine and potassium) were recorded on the day of LTOWB transfusion and post-transfusion days 1 and 2. Group O and non-Group O recipients were compared. RESULTS Twenty-one children were included. Their median (interquartile range [IQR]) weight was 12 kg (12-18) with minimum 2.8 kg, and median (IQR) age was 3 years (1.75-5.00) with minimum 0.08 years (29 days old). The most common indication for transfusion was trauma (17/21; 81%). The median (IQR) volume of LTOWB transfused was 30 mL/kg (20-42). There were 9 non-group O and 12 group O recipients. There were no statistically significant differences in the median concentrations of any of the biochemical markers of hemolysis or the renal function markers between the non-group O and the group O recipients at any of the three time points (p > 0.05 for all comparisons). There were also no statistically significant differences in demographic parameters or clinical outcomes including 28-day mortality, length of stay, ventilator days, and venous thromboembolism between the groups. No transfusion reactions were reported in either group. CONCLUSION These data suggest LTOWB use is safe in children weighing less than 20 kg. Further multi-center studies and larger cohorts are needed to confirm these results.

Abstract
BACKGROUND Traumatic injury is the leading cause of death in children and adolescents. Hemorrhagic shock remains a common and preventable cause of death in the pediatric trauma patients. A paucity of high-quality evidence is available to guide specific aspects of hemorrhage control in this population. We sought to identify high-priority research topics for the care of pediatric trauma patients in hemorrhagic shock. METHODS A panel of 16 consensus multidisciplinary committee members from the Pediatric Traumatic Hemorrhagic Shock Consensus Conference developed research priorities for addressing knowledge gaps in the care of injured children and adolescents in hemorrhagic shock. These ideas were informed by a systematic review of topics in this area and a discussion of these areas in the consensus conference. Research priorities were synthesized along themes and prioritized by anonymous voting. RESULTS Eleven research priorities that warrant additional investigation were identified by the consensus committee. Areas of proposed study included well-designed clinical trials and evaluations, including increasing the speed and accuracy of identifying and treating hemorrhagic shock, defining the role of whole blood and tranexamic acid use, and assessment of the utility and appropriate use of viscoelastic techniques during early resuscitation. The committee recommended the need to standardize essential definitions, data elements, and data collection to facilitate research in this area. CONCLUSION Research gaps remain in many areas related to the care of hemorrhagic shock after pediatric injury. Addressing these gaps is needed to develop improved evidence-based recommendations for the care of pediatric trauma patients in hemorrhagic shock.

The First Two Years of the Association of Pediatric Surgery Training Program Directors (APSTPD) Transition to Fellowship Course: Lessons Learned and Future Directions. JOURNAL OF SURGICAL EDUCATION 2023; 80:62-71. [PMID: 36085115 DOI: 10.1016/j.jsurg.2022.08.006] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Subscribe] [Scholar Register] [Received: 07/07/2022] [Revised: 08/08/2022] [Accepted: 08/13/2022] [Indexed: 06/15/2023]
Abstract
OBJECTIVE The first transition to fellowship course for incoming pediatric surgery fellows was held in the US in 2018 and the second in 2019. The course aimed to facilitate a successful transition in to fellowship by introduction of the professional, patient care, and technical aspects unique to pediatric surgery training. The purpose of this study was to evaluate the feasibility and effectiveness of the first two years of this course in the US and discuss subsequent evolution of this endeavor. DESIGN This is a descriptive and qualitative analysis of two years' experience with the Association of Pediatric Surgery Training Program Directors' (APSTPD) Transition to Fellowship course. Course development and curriculum, including clinical knowledge, soft skills, and hands-on skills labs, are presented. Participating incoming fellows completed multiple choice, boards-style pre- and post-tests. Scores were compared to determine if knowledge was effectively transferred. Participants also completed post-course evaluations and subsequent 3- or 12-month surveys inquiring on the lasting impact of the course on their transition into fellowship. Standard univariate statistics were used to present results. SETTING The first APSTPD Transition to Fellowship course was held at the Johns Hopkins Hospital in Baltimore, Maryland in 2018, and the second course was held at the Oregon Health and Science University in Portland, Oregon in 2019. PARTICIPANTS All fellows entering ACGME-certified Pediatric Surgery fellowships in the United States were invited to participate. Twenty fellows accepted and attended in 2018, and fourteen fellows participated in 2019. RESULTS There were 34 incoming pediatric surgery fellow participants over 2 years. Faculty represented more than 10 institutions each year. Pre- and post-test scores were similar between years, with a significant improvement of scores after completion of the course (67±10% vs 79±8%, p < 0.001). Feedback from participants was overwhelmingly positive, with skills labs being attendees' favorite component. When asked about usefulness of individual course sessions, more attendees found clinical sessions more useful than soft skills (93% vs 73%, p = 0.011). Almost all (90%) of participants reported the course met its stated purpose and would recommend the course to future fellows. This was further reflected on 3 and 12 month follow up surveys wherein 85% stated they found the course helpful during the first few months of fellowship and 90% would still recommend it. CONCLUSIONS A transition to fellowship course in the US for incoming pediatric surgery fellows is logistically feasible, effective in transfer of knowledge, and highly regarded among attendees. Feedback from each course has been used to improve the subsequent courses, ensuring that it remains a valuable addition to pediatric surgical training in the US.

Abstract
ABSTRACT Hemorrhagic shock in pediatric trauma patients remains a challenging yet preventable cause of death. There is little high-quality evidence available to guide specific aspects of hemorrhage control and specific resuscitation practices in this population. We sought to generate clinical recommendations, expert consensus, and good practice statements to aid providers in care for these difficult patients.The Pediatric Traumatic Hemorrhagic Shock Consensus Conference process included systematic reviews related to six subtopics and one consensus meeting. A panel of 16 consensus multidisciplinary committee members evaluated the literature related to 6 specific topics: (1) blood products and fluid resuscitation for hemostatic resuscitation, (2) utilization of prehospital blood products, (3) use of hemostatic adjuncts, (4) tourniquet use, (5) prehospital airway and blood pressure management, and (6) conventional coagulation tests or thromboelastography-guided resuscitation. A total of 21 recommendations are detailed in this article: 2 clinical recommendations, 14 expert consensus statements, and 5 good practice statements. The statement, the panel's voting outcome, and the rationale for each statement intend to give pediatric trauma providers the latest evidence and guidance to care for pediatric trauma patients experiencing hemorrhagic shock. With a broad multidisciplinary representation, the Pediatric Traumatic Hemorrhagic Shock Consensus Conference systematically evaluated the literature and developed clinical recommendations, expert consensus, and good practice statements concerning topics in traumatically injured pediatric patients with hemorrhagic shock.

Abstract
More than twenty years ago, the Accreditation Council for Graduate Medical Education and the American Board of Medical Specialties began the conversion of graduate medical education from a structure- and process-based model to a competency-based framework. The educational outcomes assessment tool, known as the Milestones, was introduced in 2013 for seven specialties and by 2015 for the remaining specialties, including pediatric surgery. Designed to be an iterative process with improvements over time based on feedback and evidence-based literature, the Milestones started the evolution from 1.0 to 2.0 in 2016. The formation of Pediatric Surgery Milestones 2.0 began in 2019 and was finalized in 2021 for implementation in the 2022-2023 academic year. Milestones 2.0 are fewer in number and are stated in more straightforward language. It incorporated the harmonized milestones, subcompetencies for non-patient care and non-medical knowledge that are consistent across all medical and surgical specialties. There is a new Supplemental Guide that lists examples, references and links to other assessment tools and resources for each subcompetency. Milestones 2.0 represents a continuous process of feedback, literature review and revision with goals of improving patient care and maintaining public trust in graduate medical education's ability to self-regulate.

Abstract
BACKGROUND The role of age and sex in mediating coagulation characteristics in injured children is not well defined. We hypothesize that thromboelastography (TEG) profiles are equivalent across sex in younger children and diverge after puberty. METHODS Consecutive trauma patients younger than 18 years were identified from a university-affiliated, Level I, pediatric trauma center (2016-2020) database. Demographics, injury characteristics, and TEG parameters were recorded. Children were categorized by sex and age (younger, ≤10 years; older, ≥11 years). Baseline characteristics, outcomes, and TEG parameters were compared using nonparametric tests as appropriate. To account for the effects of confounding variables, analysis of covariance was performed controlling for Injury Severity Score (ISS), admission Glasgow Coma Scale score, and pediatric age-adjusted shock index. RESULTS Six hundred forty-seven subjects were identified (70.2% male, median ISS, 10; interquartile range, 5-24; blunt mechanism, 75.4%). Among 395 younger children (≤10 years), there were no differences in TEG characteristics between sexes. Among 252 adolescents (≥11 years), males had greater kinetic times (1.8 vs. 1.4 min; p < 0.001), decreased alpha angles (69.6° vs73.7°; p < 0.001), and lower maximum amplitudes (59.4 vs. 61.5 mm; p = 0.01). Fibrinolysis was significantly lower in older females compared with younger females (0.4% vs. 1.5%, p < 0.001) and age-matched males (0.4% vs. 1.0%, p = 0.02). Compared with younger male children, adolescent males had greater kinetic times (1.8 vs. 1.4 min; p < 0.001), decreased alpha angles (73.5° vs. 69.6°, p < 0.001), lower maximum amplitudes (59.4 vs. 62 mm, p < 0.001), and less fibrinolysis (1.0% vs. 1.3%, p = 0.03). This interaction persisted after controlling for ISS, Glasgow Coma Scale, and pediatric age-adjusted shock index. CONCLUSION Sex dimorphisms in TEG coagulation profiles appear after puberty. This divergence appears to be driven by a shift in male coagulation profiles to a relatively hypocoagulable state and female coagulation profiles to a relatively hypercoagulable state after puberty. LEVEL OF EVIDENCE Prognostic and Epidemiologic, Level III.

Abstract
OBJECTIVES To define the clinical characteristics of hospitalized children with moderate traumatic brain injury and identify factors associated with deterioration to severe traumatic brain injury. DESIGN Retrospective cohort study. SETTING Tertiary Children's Hospital with Level 1 Trauma Center designation. PATIENTS Inpatient children less than 18 years old with an International Classification of Diseases code for traumatic brain injury and an admission Glasgow Coma Scale score of 9-13. MEASUREMENTS AND RESULTS We queried the National Trauma Data Bank for our institutional data and identified 177 patients with moderate traumatic brain injury from 2010 to 2017. These patients were then linked to the electronic health record to obtain baseline and injury characteristics, laboratory data, serial Glasgow Coma Scale scores, CT findings, and neurocritical care interventions. Clinical deterioration was defined as greater than or equal to 2 recorded values of Glasgow Coma Scale scores less than or equal to 8 during the first 48 hours of hospitalization. Thirty-seven patients experienced deterioration. Children who deteriorated were more likely to require intubation (73% vs 26%), have generalized edema, subdural hematoma, or contusion on CT scan (30% vs 8%, 57% vs 37%, 35% vs 16%, respectively), receive hypertonic saline (38% vs 7%), undergo intracranial pressure monitoring (24% vs 0%), were more likely to be transferred to inpatient rehabilitation following hospital discharge (32% vs 5%), and incur greater costs of care ($25,568 vs $10,724) (all p < 0.01). There was no mortality in this cohort. Multivariable regression demonstrated that a higher Injury Severity Score, a higher initial international normalized ratio, and a lower admission Glasgow Coma Scale score were associated with deterioration to severe traumatic brain injury in the first 48 hours (p < 0.05 for all). CONCLUSIONS A substantial subset of children (21%) presenting with moderate traumatic brain injury at a Level 1 pediatric trauma center experienced deterioration in the first 48 hours, requiring additional resource utilization associated with increased cost of care. Deterioration was independently associated with an increased international normalized ratio higher Injury Severity Score, and a lower admission Glasgow Coma Scale score.

Safety profile of low-titer group O whole blood in pediatric patients with massive hemorrhage. Transfusion 2021; 61 Suppl 1:S8-S14. [PMID: 34269441 DOI: 10.1111/trf.16456] [Citation(s) in RCA: 7] [Impact Index Per Article: 2.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/22/2020] [Revised: 12/08/2020] [Accepted: 12/10/2020] [Indexed: 12/01/2022]
Abstract
BACKGROUND Low-titer Group O Whole Blood (LTOWB) is used with increasing frequency in adult and pediatric trauma and massive bleeding transfusion protocols. There is a risk of acute hemolytic reactions in non-group O recipients due to the passive transfusion of anti-A and anti-B in the LTOWB. This study investigated the hemolysis risk among pediatric recipients of LTOWB. STUDY DESIGN AND METHODS Blood bank records were queried for pediatric recipients of LTOWB between June 2016 and August 2020 and merged with clinical data. The primary outcome was laboratory evidence of hemolysis as manifested by changes in lactate dehydrogenase (LDH), haptoglobin, total bilirubin, reticulocyte count, potassium, and creatinine. Per protocol, these values were collected on hospital days 0-2 for recipients of LTOWB. Transfusion reactions were reported to the hospital's blood bank. RESULTS Forty-seven children received LTOWB transfusion between 2016 and 2020; 21 were group O and 26 were non-group O. The groups were comparable in terms of the total volume of transfused blood products, demographics, and clinical outcomes. The most common indication for LTOWB transfusion was hemorrhagic shock due to trauma. There were no clinically or statistically significant differences in baseline, post-transfusion day 1, or post-transfusion day 2 hemolysis markers between the group O and non-group O LTOWB recipients. There were no adverse events or transfusion reactions reported. DISCUSSION Use of up to 40 ml/kg of LTOWB appears to be serologically safe for children in hemorrhagic shock.

Abstract
BACKGROUND Low-titer group O whole-blood (LTOWB) is being used for children with life-threatening traumatic bleeding. A survey was conducted to determine current LTOWB utilization and interest in participation in a randomized control trial (RCT) of LTOWB versus standard blood component transfusion in this population. STUDY DESIGN AND METHODS Transfusion medicine (TM) directors and pediatric trauma directors at 36 US children's hospitals were surveyed by e-mail in June 2020. Hospitals were selected by participation in the Massive Transfusion Epidemiology and Outcomes in Children Study or being among the largest 30 children's hospitals by bed capacity per the Becker Hospital Review. RESULTS The response rate was 83.3% (30/36) from TM directors and 88.9% (32/36) from trauma directors. The median of massive transfusion protocol activations for traumatic bleeding was reported as 12 (IQR 5.8-20) per year by TM directors. LTOWB was used by 18.8% (6/32) of trauma directors. Survey responses indicate that 86.7% (26/30) of TM directors and 90.6% (29/32) of trauma directors either moderately or strongly agree that a LTOWB RCT is important to perform. About 83.3% (25/30) of TM directors and 93.8% (30/32) of trauma directors were willing to participate in the proposed trial. About 80% (24/30) of TM directors and 71.9% (23/32) of trauma directors would transfuse RhD+ LTOWB to male children, but fewer would transfuse Rh + LTOWB to females [20% (6/30) TM directors and 37.5% (12/32) of trauma directors]. CONCLUSIONS A majority of respondents supported an RCT comparing LTOWB to component therapy in children with severe traumatic bleeding.

Abstract
BACKGROUND A Mobile Safety Center (MSC) provides safety resources to families to prevent pediatric injury. The primary objective of this study was to assess the impact of an MSC on home safety behaviors. METHODS We conducted a prospective observational study with 50 parents and guardians recruited at community events attended by an MSC. Participants completed a pre-test assessing demographics and home safety behaviors prior to participating in the MSC's home safety educational program. We conducted follow-up with participants 4 weeks (follow-up 1) and 6 months (follow-up 2) after their visit to the MSC to reassess home safety behaviors. We used descriptive statistics in addition to Friedman, Wilcoxon sum-rank, and Fisher's exact testing to analyze respondent demographics and changes in home safety practices. Friedman and Wilcoxon sum-rank testing was performed only for participants who completed all surveys. RESULTS Of our 50 participants, 29 (58%) completed follow-up 1, 30 (60%) completed follow-up 2, and 26 (52%) completed both. Participants were more likely to have a fire-escape plan at follow-up 1 than on the pre-test (p = 0.014). They were also more likely to have the Poison Control Hotline number accessible in their cellphone or near a home phone at follow-up 1 compared to the pre-test (p = 0.002) and follow-up 2 compared to the pre-test (p < 0.001). Families with at least one household member who smoked or used e-cigarettes at any point during the study (n = 16 for the total population, n = 9 for those who completed both surveys) were less likely to have more than two smoke detectors installed at home during the pre-test (p = 0.049). However, this significantly changed across timepoints (p = 0.018), and while 44.4% reported more than two detectors during the pre-test, 88.9% reported this at both follow-ups. CONCLUSIONS Home safety education through an MSC positively changed some reported safety behaviors and maintained these changes at long-term follow-up. By encouraging the adoption of better home safety practices, education at an MSC may decrease pediatric injury rates.

Abstract
BACKGROUND Low titer group O whole blood (LTOWB) is used as the initial resuscitative fluid in an increasing number of pediatric trauma and massive bleeding transfusion protocols. There is little data on adverse events following its transfusion in pediatric trauma patients. STUDY DESIGN AND METHODS Blood bank records were queried for pediatric recipients of at least one unit of red blood cells (RBCs) (component group) or LTOWB (LTOWB group) within 24 h of admission between May 2013 and August 2020. Subjects with early death (<72 h) were excluded. Propensity-score matching of LTOWB and component groups was performed. Adverse events were recorded, including transfusion reaction, thromboembolism, acute kidney injury, sepsis, and organ failure based on PELOD-2 score, along with hospital and ICU length of stay (LOS) and ventilator days. RESULTS Thirty-six LTOWB recipients were matched to 36 conventional component recipients. Subjects were 52% male, with blunt injury mechanism (82%), median (IQR) injury severity score = 27 (21-35), and 26% in-hospital mortality. The groups were well matched in terms of demographics and injury characteristics. There were no clinically or statistically significant differences in adverse outcomes including reported transfusion reaction, organ failure, acute kidney injury, sepsis/bacteremia, and venous thromboembolism. Hospital LOS, ventilator days, mortality, and functional disability at discharge were also not significantly different. The LTOWB group had significantly shorter ICU LOS compared to the component group. CONCLUSION LTOWB transfusion did not increase the risk of adverse events in children. However, larger studies are required to confirm these results.

An Evaluation of Pediatric Secondary Overtriage in the Pennsylvania Trauma System. J Surg Res 2021; 264:368-374.

Abstract
BACKGROUND We sought to determine the secondary overtriage rate of pediatric trauma patients admitted to pediatric trauma centers. We hypothesized that pediatric secondary overtriage (POT) would constitute a large percentage of admissions to PTC. MATERIALS AND METHODS The Pennsylvania Trauma Outcome Study database was retrospectively queried from 2003 to 2017 for pediatric (age ≤ 18 y) trauma patients transferred to accredited pediatric trauma centers in Pennsylvania (n = 6). Patients were stratified based on discharge within (early) and beyond (late) 24 h following admission. POT was defined as patients transferred to a PTC with an early discharge. Multilevel mixed-effects logistic regression model controlling for demographic and injury severity covariates were utilized to determine the adjusted impact of injury patterns on early discharge. RESULTS A total of 37,653 patients met inclusion criteria. For transfers, POT compromised 18,752 (49.8%) patients. Compared to POT, non-POT were more severely injured (ISS: 10 versus 6;P < 0.001) and spent less time in the ED (Min: 181 versus 207;P < 0.001). In adjusted analysis, concussion, closed skull vault fractures, supracondylar humerus fractures, and consults to neurosurgery were associated with increased odds of POT. Overall, femur fracture, child abuse evaluation, and consults to plastic surgery, orthopedics, and ophthalmology were all associated with a decreased risk of being POT. CONCLUSIONS POT comprises 49.8% of PTC transfer admissions in Pennsylvania's trauma system. Improving community resources for management of pediatric concussion and mild TBI could result in decreased rates of POT to PTCs. Developing better inter-facility transfer guidelines and increased education of adult TC and nontrauma center hospitals is needed to decrease POT. LEVEL OF EVIDENCE Epidemiologic study, level III.

Abstract
OBJECTIVES To evaluate the incidence of anemia in patients with abusive head trauma (AHT), noninflicted traumatic brain injury (TBI), and physical abuse without AHT and the effect of anemia on outcome. STUDY DESIGN In a retrospective, single-center cohort study, we included children under the age of 3 years diagnosed with either AHT (n = 75), noninflicted TBI (n = 77), or physical abuse without AHT (n = 60) between January 1, 2014, and December 31, 2016. Neuroimaging was prospectively analyzed by pediatric neuroradiologists. Primary outcome was anemia at hospital presentation. Secondary outcomes included unfavorable outcome at hospital discharge, defined as a Glasgow Outcome Scale between 1 and 3, and intracranial hemorrhage (ICH) volume. RESULTS Patients with AHT had a higher rate of anemia on presentation (47.3%) vs noninflicted TBI (15.6%) and physical abuse without AHT (10%) (P < .001). Patients with AHT had larger ICH volumes (33.3 mL [10.1-76.4 mL] vs 1.5 mL [0.6-5.2 mL] ; P < .001) and greater ICH/total brain volume percentages than patients with noninflicted TBI (4.6% [1.4-8.2 %] vs 0.2% [0.1-0.7%]; P < .001). Anemia was associated with AHT (OR, 4.7; 95% CI, 2.2-10.2) and larger ICH/total brain volume percentage (OR, 1.1; 95% CI, 1.1-1.2) in univariate analysis. Unfavorable outcome at hospital discharge was associated with anemia (OR, 4.4; 95% CI, 1.6-12.6) in univariate analysis, but not after controlling for covariates. CONCLUSIONS Patients with AHT were more likely to present to the hospital with anemia and increased traumatic ICH volume than patients with noninflicted TBI or physical abuse without AHT. Children with anemia and AHT may be at increased risk for an unfavorable outcome.

Abstract
BACKGROUND Approximately 75% of all bicycle-related mortality is secondary to head injuries, 85% of which could have been prevented by wearing a bicycle helmet. Younger children appear to be at greater risk than adults, yet helmet use is low despite this risk and legislation and ordinances requiring helmet use among younger riders. We sought to determine whether bicycle helmets are associated with the incidence and severity of head injury among pediatric bicyclists involved in a bicycle crash involving a motor vehicle. METHODS We performed a retrospective review of patients age ≤ 18 years hospitalized at a level I pediatric trauma center between January 1, 2008, and December 31, 2018. Data were abstracted from the institutional trauma registry and electronic medical record. International Classification of Diseases 9th and 10th editions and external causes of injury codes were used to identify MV related bicycle crashes and determine the abbreviated injury severity (AIS) for head injury severity. Injury narratives were reviewed to determine helmet use. We calculated the incidence of head injury from bicycle vs. MV crashes utilizing descriptive statistics. We analyzed the risk and severity of injury utilizing univariate and multivariate logistic regression. RESULTS Overall, 226 bicyclists were treated for injuries from being struck by a MV. The median age was 11 (interquartile range (IQR): 8 to 13) years. Helmeted bicyclists (n = 26, 27%) were younger (9.4 years versus 10.8 years, p = 0.04), and were less likely (OR 0.21, 95% CI 0.09 to 0.49) to be diagnosed with a head injury compared to unhelmeted bicyclists (n = 199). Of those with a head injury, helmeted bicyclists were less likely (OR 0.57, 95% CI 0.11-2.82) to sustain severe or higher injury using AIS. When adjusting for demographics (age, sex, race) and injury severity, helmet use predicted a reduction in head injury (OR 6.02, 95% CI 2.4-15.2). CONCLUSIONS Bicycle helmet use was associated with reduced odds of head injury and severity of injury.. These results support the use of strategies to increase the uptake of bicycle helmets wearing as part of a comprehensive youth bicycling injury prevention program.

Abstract
Background A Mobile Safety Center (MSC) is designed to remove financial accessibility barriers to home safety by providing education and safety devices within local communities. The objective of this study was to evaluate the impact of an MSC on pediatric home safety knowledge and device use. Methods We conducted a prospective home safety interventional study. Parents and grandparents with children at home were recruited at community events attended by the MSC. Participants completed a pre-test survey assessing demographics and current home safety knowledge, practices, and device use. Participants then attended the MSC’s short home safety educational program. Afterwards, participants completed a knowledge reassessment post-test and were offered free safety devices: a smoke detector, a gun lock, and a childproofing kit comprising outlet covers, doorknob covers, and cabinet latches. We administered two follow-up surveys four weeks and six months after visiting the MSC. Descriptive statistics, Friedman tests, Wilcoxon Sum-Rank tests, and Pearson Chi-Square were used to assess respondent demographic characteristics and changes in home safety knowledge, practices, and device use. Results We recruited 50 participants, of whom 29 (58%) completed follow-up 1, 30 (60%) completed follow-up 2, and 26 (52%) completed both. Participants who completed both follow-ups increased total correct answers to safety knowledge questions between the pre-test and post-test (p = 0.005), pre-test and follow-up 1 (p = 0.003), and pre-test and follow-up 2 (p = 0.012) with no significant changes between the post-test, follow-up 1, and follow-up 2. Of the respondents who reported accepting safety products, outlet covers were used most frequently, followed by the smoke detector, doorknob covers, cabinet latches, and the gun lock. Conclusions The MSC may be an effective means of increasing home safety among families with children, as participation in the MSC’s home safety educational program significantly increased home safety knowledge and spurred home safety device use. Implementation of MSCs could potentially reduce childhood injury rates within communities through promotion of home safety.

Abstract
Trauma-induced coagulopathy (TIC) is well documented in injured children. However, many important features of pediatric hemostasis are still in development in early childhood and may impact TIC. Certain pediatric subgroups are at a higher risk. Traumatic brain injury, which occurs with a higher rate in children, and physical child abuse are known risk factors for TIC that deserve special consideration. Resuscitation of a pediatric trauma patient follows many of the same goals as in the injured adult trauma, although some key aspects of pediatric resuscitation require ongoing investigation. Venous thromboembolism occurs with higher rates in certain high-risk groups of pediatric trauma patients, although overall it is considerably less frequent in children as compared with adults.

Abstract
Objectives The purpose of this study was to examine the injury risk patterns among Amish children, many of whom may be exposed to uncommon injuries and limited access to care due to their agrarian lifestyle and remote communities. Design Retrospective Chart Review. Methods With IRB approval, we performed a retrospective review of Amish patients age ≤ 12 years presenting to a level I pediatric trauma center between January 1, 2005, and December 31, 2015. Data abstracted from the institutional trauma registry and electronic medical record were analyzed using descriptive statistics and univariate/multivariate analysis. Results One hundred eighty-three Amish children were admitted, and 2 died from injuries. Patients were 72.1% male; the median age was 5 (IQR 3–8); median injury severity score (ISS) was 9 (IQR 4–14), Most injuries were the result of blunt force trauma (91.8%). The most frequent mechanisms were falls (42.6%), followed by animal-related (15.3%), and buggy (12.5%). Most injuries occurred at home (44.4%) or on a farm (33.9%). Hay hole falls were a unique source of injury with a high ISS (12; IQR 6–17). The overall median length of stay (LOS) was 2 days (IQR 1–3), with animal-related injuries associated with the longest LOS (3 days; IQR 1–4.75). Conclusions The majority of injuries among Amish children are due to falls. Hay hole falls and animal-related injuries result in the highest ISS and longest LOS. These findings identify the farm as a potential target for culturally appropriate interventions for risk modification.

Abstract
We compared risk factors and outcomes of children injured from all-terrain vehicle (ATV) injuries to those injured from motor vehicle collisions (MVC). We reviewed records of patients ≤18 years of age admitted to a trauma center with ATV- or MVC-related injuries between January 1, 2000, and December 31, 2015. Demographics were compared using logistic regression. Rates of injuries were compared using χ2 tests. Of 6293 patients, 1140 (18%) ATV and 5153 (82%) MVC events were identified. In multivariable analysis (adjusted odds ratio [aOR], 95% confidence interval [CI]), patients with ATV-related injuries occurred more at older age (≥12 years; aOR = 4.29, 95% CI = 3.20-5.77), in rural counties (aOR = 3.72, 95% CI = 2.62-5.28), in regions with lower median household income (aOR = 1.37, 95% CI = 1.03-1.83), and in the spring (aOR = 2.44, 95% CI = 1.87-3.18), and summer (aOR = 2.50, 95% CI = 1.93-3.25) compared with winter. ATV-related injuries occurred less frequently among females (aOR = 0.76, 95% CI = 0.65-0.89). Upper extremity injuries were associated with ATV-related injuries (P ≤ .001). Findings may facilitate identification of at-risk groups for targeted interventions.

Abstract
Despite over a half-century of recognizing fibrinolytic abnormalities after trauma, we remain in our infancy in understanding the underlying mechanisms causing these changes, resulting in ineffective treatment strategies. With the increased utilization of viscoelastic hemostatic assays (VHAs) to measure fibrinolysis in trauma, more questions than answers are emerging. Although it seems certain that low fibrinolytic activity measured by VHA is common after injury and associated with increased mortality, we now recognize subphenotypes within this population and that specific cohorts arise depending on the specific time from injury when samples are collected. Future studies should focus on these subtleties and distinctions, as hypofibrinolysis, acute shutdown, and persistent shutdown appear to represent distinct, unique clinical phenotypes, with different pathophysiology, and warranting different treatment strategies.

Abstract
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.

Abstract
Background: Identifying problem drinkers and providing brief intervention (BI) for those who screen positive are required within all level I trauma centers. While parent-adolescent relationships impact adolescent alcohol use, parenting skills are rarely included in adolescent alcohol BIs within pediatric trauma centers. Introduction: The primary objective of this study was to examine the feasibility and acceptability of an electronic parenting skills intervention for parents of injured adolescents who report alcohol or drug use. Materials and Methods: Across three pediatric level I trauma centers, admitted trauma patients 12-17 years of age, screening positive for alcohol or drug use, were consented along with one parent. Adolescent-parent dyads were enrolled and assigned to the intervention (Parenting Wisely web-based modules coupled with text messaging) or standard care conditions using a 2:1 allocation ratio. Teens completed 3- and 6-month follow-up surveys; parents completed 3-month follow-up surveys. Results: Thirty-seven dyads were enrolled into the study. Only one-third of parents accessed the web-based Parenting Wisely after baseline. All parents completed the text message program. At 3-month follow-up, 78% of parents endorsed that they would recommend the program to others. There were no significant differences in adolescent substance use or parenting behaviors between groups at follow-up. Discussion: A texting component is well received, but web-based components may be underutilized. Larger studies are necessary to determine if an electronic skills intervention has an effect on parenting skills and adolescent substance use. Conclusions: This study demonstrated accessibility and feasibility of an e-parenting intervention with more utilization of text components than web-based.

Abstract
INTRODUCTION Alcohol screening, brief intervention and referral to treatment is mandated within the level 1 pediatric trauma center. However, data on the prevalence of alcohol and drug use among admitted pediatric trauma patients is limited. Our study objective was to describe substance use and related negative consequences in admitted adolescent trauma patients across three pediatric level 1 trauma centers. METHODS This surveillance study was nested within a study on electronically delivered parenting skills education to parents of admitted adolescents (12-17 years) screening positive for alcohol or drug use. Enrolled adolescents completed baseline assessments to examine demographics, substance use and related negative consequences. Thirty-seven parent-adolescent dyads enrolled in the intervention study. RESULTS Participants were eligible if they received a positive CRAFFT score or a positive biological screen for alcohol or drug use at time of the hospital admission. Of those enrolled into the study, 9 (24%) reported no substance use in the prior 12 months in our assessment battery. Of the remaining 28 patients, 6 (16%) reported using only alcohol, 10 (27%) only marijuana, 9 (24%) both alcohol and marijuana, and 3 (8%) alcohol and marijuana with other drugs in the past 12 months. Negative consequences reported varied between those who reported alcohol use only and those who reported marijuana use only with physical consequences of use most often being reported by those using alcohol (hangover, vomiting), and psychosocial consequences (getting into trouble with parents, doing something later regret) by those who used only marijuana. CONCLUSION These findings support the use of laboratory screening and screening questionnaires for all adolescent trauma admissions to capture a complete picture of alcohol and drug use.

Abstract
BACKGROUND Diagnostic imaging of pediatric blunt abdominal trauma is evolving in light of increased attention to radiation exposure. We hypothesize that the implementation of imaging guidelines has reduced total CT scans without missing clinically significant injury. METHODS We retrospectively reviewed blunt trauma patients age 0-17 with solid organ injury who underwent CT scan at our academic level 1 pediatric trauma center between 2005 and 2014. Variables including total annual trauma admissions and CT scans, demographics, injury characteristics, and procedures were recorded. Descriptive statistics, Fisher exact and rank sum testing were performed. p<0.05 defined significance. RESULTS Overall percentage of abdominal CT scans decreased significantly after protocol implementation. There were 498 solid organ injuries in 403 subjects. There was a significant decrease in the median percentage of low grade injuries (1.3% versus 0.6%; p=0.019) but no difference in high grade injuries (1.3% versus 1.1%; p=0.394). No patient had death, readmission or delayed diagnosis of injury requiring intervention. CONCLUSION Implementation of imaging guidelines for blunt abdominal trauma decreased the incidence of low grade solid organ injuries at our institution, but did not inhibit diagnosis and safe management of high grade injuries. Selective imaging of trauma patients decreases childhood radiation exposure and does not result in delayed bleeding or death. LEVEL OF EVIDENCE Level III, retrospective study.

Abstract
BACKGROUND Trauma-induced coagulopathy is common and associated with poor outcome in injured children. Our aim is to identify patterns of coagulation dysregulation after injury and associate these phenotypes with relevant clinical outcomes. METHODS We performed principal components analysis on prospectively collected data from children with the highest-level trauma activation June 2015-June 2016. Parameters included admission international normalized ratio, platelet count and thromboelastograms. Variables were reduced to principal components; principal component scores were generated for each subject and used in logistic regression with outcomes including mortality, disability, venous thromboembolism, and blood transfusion in the first 24 hours. RESULTS We included 133 subjects with median interquartile range age =10 (5-13 years), median interquartile range Injury Severity Score =17 (9-25), 73.5% boys, 70.8% blunt trauma. principal component analysis identified 3 significant principal components accounting for 75.0% of overall variance. Principal component 1 reflected clot strength; principal component 2 reflected abnormal fibrinolysis, both hyperfibrinolysis and fibrinolysis shutdown; principal component 3 reflected global clotting factor depletion. High principal component 1 score was associated with increased mortality (odds ratio =1.63) and blood transfusion (odds ratio 1.36). Principal component 2 score was correlated with Injury Severity Score (rho 0.4) and associated with venous thromboembolism (odds ratio 1.84), functional disability (odds ratio 1.66), mortality (odds ratio 2.07) and blood transfusion (odds ratio 2.79). PC3 score was associated with increased mortality (odds ratio 1.92) and blood transfusion (odds ratio 1.25). CONCLUSION Principal component analysis detects 3 patterns of coagulation dysregulation using widely available laboratory parameters: (1) abnormalities in clot strength; (2) abnormalities in fibrinolysis, and (3) clotting factor depletion. While all were associated with mortality and transfusion, fibrinolytic dysregulation was associated with injury severity and portends particularly poor outcome including venous thromboembolism and disability.

Abstract
INTRODUCTION Transanastomatic feeding tube (TAT) use in the repair of tracheoesophageal fistulas (TEF) with or without esophageal atresia (EA) and EA with or without TEF allows for earlier enteral feedings, however, may predispose to esophageal stricture. METHODS We review our institutional experience with esophageal atresia repair over a 15-year period from 2000 to 2015 and report on our observed complication rate with emphasis on the surgical approach and use of TATs. RESULTS We identified 110 TEF repairs. Ninety-six were Type C, 7 were Type A, 4 were Type D, and 3 were Type E (H-Type). TATs were used in 74% of patients. The stricture rate with the TAT approached 56% versus 17% without a TAT (p<0.0005). There was no difference in leak rate (p=0.27). Ninety-four TEF repairs were performed via open thoracotomy, and 16 were initially approached thoracoscopically. Six out of 16 that were started thoracoscopically were completed with the minimally invasive approach. Whether the case was started thoracoscopically, completed thoracoscopically, or performed open made no difference in the rate of stricture or anastomotic leak, but we did observe an increase in musculoskeletal complications in the open thoracotomy group (28% vs. 0). CONCLUSION Our data suggests that the use of TATs does not protect against anastomotic leak, but may increase stricture rate. Further, the thoracoscopic group showed no difference in the leak or stricture rate and demonstrated less musculoskeletal complications. Confirmation of these findings will require a prospective study. LEVEL OF EVIDENCE III.

Abstract
BACKGROUND Lymphatic mapping to guide sentinel lymph node biopsy (SLNB) typically requires lymphoscintigraphy prior to surgery. In young pediatric patients, this process often requires intubation in the nuclear medicine suite followed by transport to the operating room (OR). METHODS We reviewed 14 pediatric cases in which a portable nuclear imaging camera was utilized to perform the entirety of the SLNB in the OR. RESULTS AND CONCLUSION This method, utilizing intraoperative nuclear imaging, helped to confirm removal of the sentinel lymph node in real time, decreased anesthesia time, and avoided transport of a sedated or intubated child.

Abstract
BACKGROUND/PURPOSE Playground track ride and homemade zipline-related injuries are increasingly common in the emergency department, with serious injuries and even deaths reported. METHODS Retrospective review of the National Electronic Injury Surveillance System (NEISS) database (2009-2015), followed by review of our academic pediatric trauma center's prospectively-maintained database (2005-2013). We included children ages 0-17years of age with zipline-related injuries. We recorded annual incidence of zipline-related injury, zipline type (homemade or playground), injuries and mechanism. RESULTS In the NEISS database, 9397 (95%CI 6728-12,065) total zipline-related injuries were reported (45.9% homemade, 54.1% playground). Homemade but not playground injuries increased over time. Common injuries were fracture (49.8%), contusion/laceration (21.2%) and head injury (12.7%). Fall was predominant mechanism (83%). Age 5-9 was most frequently affected (59%). Our center database (n=35, 40% homemade, 1 fatality) revealed characteristics concordant with NEISS data. Head injury was related to fall height>5ft and impact with another structure. CONCLUSIONS Homemade zipline injuries are increasing. Children ages 5-9 are at particular risk and should be carefully supervised. Despite protective surfaces, playground ziplines cause significant head injury, extremity fracture and high rates of hospital admission. Playground surface standards should be reviewed and revised as needed. LEVEL OF EVIDENCE Prognosis Study, Level III.

Abstract
BACKGROUND Pediatric trauma patients are at high risk for development of venous thromboembolism (VTE). Our objective is to describe incidence, risk factors, and timing of development of VTE, anticoagulation complications, and long-term VTE outcomes in a critically injured pediatric population. PROCEDURE We did a retrospective review of pediatric (0-17 years) trauma admissions to intensive care unit from 2005 to 2014. Our center employs VTE screening and prevention protocols for high-risk patients based on hypercoagulable history, age, injuries, and medical interventions. We collected demographics, VTE prevention measures, VTE incidence, therapeutic anticoagulant use, and outcomes including postthrombotic syndrome (PTS) and clot resolution. Analysis included Wilcoxon rank-sum, Fisher exact, and logistic regression modeling. RESULTS Seven hundred fifty-three subjects were analyzed. No patients on chemical prophylaxis (21/753) developed VTE. Overall incidence of deep vein thrombosis (DVT) was 8.9%; pulmonary embolism (PE) was 0%. Time to diagnosis was median (interquartile range [IQR]) 10.5 (6.5-14.5) days, with 63% of clots being symptomatic. Risk factors for VTE development included severe traumatic brain injury (TBI), acute traumatic coagulopathy (defined by elevated admission international normalized ratio), age less than or equal to 3 or age 13 years or more, injury severity, and child abuse mechanism. At a median (IQR) follow-up of 13 (6-19) months, 52.1% had persistent clot and 15.8% had PTS. Therapeutic anticoagulation was not associated with clot resolution or prevention of PTS. CONCLUSION TBI therapy is closely linked to the development of DVT. Coagulopathy on admission is associated with hypercoagulability in the postinjury period, suggesting a patient phenotype with systemic coagulation dysregulation. Treatment was not associated with improved VTE outcomes, suggesting that pediatric protocols should emphasize VTE prevention and prophylaxis strategies.

Abstract
BACKGROUND The Injury Severity Score (ISS) is the most commonly used injury scoring system in trauma research and benchmarking. An ISS greater than 15 conventionally defines severe injury; however, no studies evaluate whether ISS performs similarly between adults and children. Our objective was to evaluate ISS and Abbreviated Injury Scale (AIS) to predict mortality and define optimal thresholds of severe injury in pediatric trauma. METHODS Patients from the Pennsylvania trauma registry 2000-2013 were included. Children were defined as younger than 16 years. Logistic regression predicted mortality from ISS for children and adults. The optimal ISS cutoff for mortality that maximized diagnostic characteristics was determined in children. Regression also evaluated the association between mortality and maximum AIS in each body region, controlling for age, mechanism, and nonaccidental trauma. Analysis was performed in single and multisystem injuries. Sensitivity analyses with alternative outcomes were performed. RESULTS Included were 352,127 adults and 50,579 children. Children had similar predicted mortality at ISS of 25 as adults at ISS of 15 (5%). The optimal ISS cutoff in children was ISS greater than 25 and had a positive predictive value of 19% and negative predictive value of 99% compared to a positive predictive value of 7% and negative predictive value of 99% for ISS greater than 15 to predict mortality. In single-system-injured children, mortality was associated with head (odds ratio, 4.80; 95% confidence interval, 2.61-8.84; p < 0.01) and chest AIS (odds ratio, 3.55; 95% confidence interval, 1.81-6.97; p < 0.01), but not abdomen, face, neck, spine, or extremity AIS (p > 0.05). For multisystem injury, all body region AIS scores were associated with mortality except extremities. Sensitivity analysis demonstrated ISS greater than 23 to predict need for full trauma activation, and ISS greater than 26 to predict impaired functional independence were optimal thresholds. CONCLUSION An ISS greater than 25 may be a more appropriate definition of severe injury in children. Pattern of injury is important, as only head and chest injury drive mortality in single-system-injured children. These findings should be considered in benchmarking and performance improvement efforts. LEVEL OF EVIDENCE Epidemiologic study, level III.

Abstract
Viscoelastic hemostatic assays (VHA), such as TEG and ROTEM, are whole blood tests that depict functional coagulation both numerically and graphically. The development of rapid VHA technology, which allows for the first data points to result within minutes of test initiation, has increased the utility of these tests in the treatment of trauma patients. Both adult and pediatric centers have integrated VHAs into trauma resuscitation and transfusion protocols. Literature regarding the use of VHAs for injured children is limited. Here, we discuss the mechanics and interpretation of VHAs as well as the use of VHAs in data-driven resuscitation of pediatric trauma patients. Novel research on fibrinolysis states after injury as well as hypercoagulable state diagnosed with VHAs are presented.

Abstract
Computed tomography (CT) scanning is an essential diagnostic tool and has revolutionized care of patients in the acute care setting. However, there is widespread agreement that overutilization of CT, where benefits do not exceed possible costs or harms, is occurring. The goal was to seek consensus in identifying and prioritizing research questions and themes that involve the comparative effectiveness of "traditional" CT use versus alternative diagnostic strategies in the acute care setting. A modified Delphi technique was used that included input from emergency physicians, emergency radiologists, medical physicists, and an industry expert to achieve this.

Abstract
Children with a button battery impaction present with nonspecific symptoms that may account for a delay in medical care. We conducted a retrospective study of the clinical presentation, management, and complications associated with button battery ingestion in the pediatric aerodigestive tract and to evaluate the associated long-term morbidity. We reviewed the medical records of 23 patients who were treated for button battery impaction at our tertiary care children's hospital from Jan. 1, 2000, through July 31, 2013. This population was made up of 14 boys and 9 girls, aged 7 days to 12 years (mean: 4 yr). Patients were divided into three groups based on the site of impaction; there were 9 impactions in the esophagus and 7 each in the nasal cavity and stomach. We compiled information on the type and size of each battery, the duration of the impaction, presenting symptoms, treatment, and outcomes. The mean duration of battery impaction was 40.6, 30.7, and 21.0 hours in the esophagus, nasal cavity, and stomach, respectively. We were able to identify the specific type of battery in 13 cases; 11 of these cases (85%) involved a 3-V 20-mm lithium ion battery, including all cases of esophageal impaction in which the type of battery was identified. The most common presenting signs and symptoms were vomiting (n = 7 [30%]), difficulty feeding (n = 5 [22%]), cough (n = 5), and bloody nasal discharge (n = 5); none of the presenting signs and symptoms predicted the severity of the injury or the outcome. The median length of hospital stay was far greater in the esophageal group (12 days) than in the nasal and stomach groups (1 day each; p = 0.006). Battery impaction in the esophagus for more than 15 hours was associated with a significantly longer postoperative hospital stay than impaction for less than 15 hours (p = 0.04). Esophageal complications included strictures (n = 5), perforation (n = 3), and tracheoesophageal fistula formation (n = 2). Clinicians should consider battery impaction in the upper aerodigestive tract as an emergency that can lead to significant long-term morbidity, and therefore immediate surgical intervention is required.

Abstract
Objectives: (1) Describe the clinical presentation, management, and complications associated with button battery impaction in the aerodigestive tract in children. (2) Evaluate the long-term morbidity associated with button battery impaction. Methods: This study is a retrospective medical record review involving 23 consecutive patients who presented to a tertiary care childrens hospital between January 1, 2000, and July 31, 2013, with button batteries impacted in the nasal cavity (n = 7), esophagus (n = 9), and stomach (n = 7). Battery type/size, duration of impaction, presenting symptoms, treatment, and outcomes were examined. Results: Average time of battery impaction was 40.6, 30.7, and 21.0 hours in the esophagus, nasal cavity, and stomach, respectively. 3V lithium batteries accounted for 84% of battery injuries and were responsible for all cases of esophageal impaction. Most common presenting symptoms were vomiting (30.4%), fever (26%), and cough (21%). Presenting signs and symptoms did not predict severity of injury or outcomes. Average length of hospitalization was greater for esophageal impactions (43.0 days) than for nasal or stomach impactions (2.0 days; P = .009). Batteries in the esophagus for >15 hours led to a longer postoperative hospital course and were associated with higher rates of transmural necrosis compared with those impacted for <15 hours ( P = .04). Esophageal complications included perforation (n = 3), tracheoesophageal fistula formation (n = 2), and strictures (n = 4). Conclusions: Button battery impactions in children present with nonspecific symptoms that may account for the delay in medical care. Clinicians must consider battery impaction in the upper aerodigestive tract as a surgical emergency that may lead to significant long-term morbidity.
