Pediatric Surgery Firearm Injury Collaborative Symposium.

Injury from a firearm is now the leading cause of death of children and youth under age 19 in the United States (U.S.) [1] and the incidence of these deaths continues to increase each year [2]. For every death from firearm violence, there are several young people who have been injured by a bullet but not killed. As pediatric surgeons, we are on the front lines of treating these young patients. We have the unforgettable memories of delivering the horrible news to parents in "quiet rooms." [3]. As these injuries fall within our scope of practice, it is incumbent on us as professionals to work to prevent these injuries, apply best practices and work for the best pathways to recovery for our patients who do survive. There is a diverse community of pediatric surgeons tackling this public health problem in a variety of ways [4]. In a pre-meeting symposium at the APSA 2023 Annual meeting, we brought together a community of pediatric surgeons working on this critical area. The following summarizes the presentations of the symposium, with topics including Risk Factors, Injury Prevention, Treatment, Public Initiatives, and National Collaborative Efforts. TYPE OF STUDY: Review Article, Proceedings of a Symposium. LEVEL OF EVIDENCE: 1 through 4 all presented.

Comparison of Pediatric Trauma Scoring Tools That Incorporate Neurological Status for Trauma Team Activation.

BACKGROUND: Two novel pediatric trauma scoring tools, SIPAB+ (defined as elevated SIPA with Glasgow Coma Scale ≤8) and rSIG (reverse Shock Index multiplied by Glasgow Coma Scale and defined as abnormal using cutoffs for early outcomes), which combine neurological status with Pediatric Age-Adjusted Shock Index (SIPA), have been shown to predict early trauma outcomes better than SIPA alone. We sought to determine if one more accurately identifies children in need of trauma team activation. METHODS: Patients 1 to 18 years old from the 2014-2018 Pediatric Trauma Quality Improvement Program database were included. Sensitivity and specificity for SIPAB+ and rSIG were calculated for components of pediatric trauma team activation, based on criteria standard definitions. RESULTS: There were 11,426 patients (1.9%) classified as SIPAB+ and 235,672 (39.0%) as having an abnormal rSIG. SIPAB+ was consistently more specific, with specificities exceeding 98%, but its sensitivity was poor (<30%) for all outcomes. In comparison, rSIG was a more sensitive tool, with sensitivities exceeding 60%, and specificity values exceeded 60% for all outcomes. CONCLUSIONS: Trauma systems must determine their priorities to decide how best to incorporate SIPAB+ and rSIG into practice, although rSIG may be preferred as it balances both sensitivity and specificity. LEVEL OF EVIDENCE: Level III.

Long-term physical and mental health outcomes of pediatric firearm-injured victims: A prospective cohort study.

BACKGROUND: Firearms are a leading cause of injury among US youth. There is little research describing outcomes after pediatric firearm injuries, particularly past 1 year. OBJECTIVE: This study aimed to assess long-term physical and mental health outcomes among nonfatal firearm versus motor vehicle collision (MVC)-injured victims and versus a standard population. METHODS: We retrospectively identified firearm and MVC-injured pediatric patients seen at one of our four trauma centers (January 2008 to October 2020) and prospectively assessed outcomes using validated patient-reported outcome measures. Eligible patients were English speaking, injured ≥5 months before study start, younger than 18 years at time of injury, and 8 years or older at study start. All firearm patients were included; MVC patients were matched 1:1 with firearm patients for Injury Severity Score (dichotomized <15 or ≥15), age range (±1 year), and year of injury. We conducted structured interviews of patients and parents using validated tools (Patient-Reported Outcomes Measurement Information System tools, Children's Impact of Event Scale for younger than 18 years and parent proxies). Patient-Reported Outcomes Measurement Information System scores are reported on a T score metric (mean [SD], 50 [10]); higher scores indicate more of the measured domain. We used paired t tests, Wilcoxon signed-rank tests, and McNemar's test to compare demographics, clinical characteristics, and outcomes. RESULTS: There were 24 participants in each of the MVC and firearm-injured groups. Compared with MVC-injured patients, firearm-injured patients younger than 18 years had similar scores, and firearm-injured patients 18 years or older had higher anxiety scores (59.4 [8.3] vs. 51.2 [9.4]). Compared with a standard population, patients younger than 18 years had worse global health scores (mean [SD], 43.4 [9.7]), and participants 18 years or older reported increased fatigue (mean [SD], 61.1 [3.3]) and anxiety (mean [SD], 59.4 [8.3]). CONCLUSION: Long-term effects of firearm-injured patients were poorer than matched MVC and the standard population in few domains. Further study in a larger, prospectively recruited cohort is warranted to better characterize physical and mental health outcomes.

Using the Social Vulnerability Index to Examine Disparities in Surgical Pediatric Trauma Patients.

INTRODUCTION: The Social Vulnerability Index (SVI) is a composite measure geocoded at the census tract level that has the potential to identify target populations at risk for postoperative surgical morbidity. We applied the SVI to examine demographics and disparities in surgical outcomes in pediatric trauma patients. METHODS: Surgical pediatric trauma patients (≤18-year-old) at our institution from 2010 to 2020 were included. Patients were geocoded to identify their census tract of residence and estimated SVI and were stratified into high (≥70th percentile) and low (<70th percentile) SVI groups. Demographics, clinical data, and outcomes were compared using Kruskal-Wallis and Fisher's exact tests. RESULTS: Of 355 patients included, 21.4% had high SVI percentiles while 78.6% had low SVI percentiles. Patients with high SVI were more likely to have government insurance (73.7% versus 37.2%, P < 0.001), be of minority race (49.8% versus 19.1%, P < 0.001), present with penetrating injuries (32.9% versus 19.7%, P = 0.007), and develop surgical site infections (3.9% versus 0.4%, P = 0.03) compared to the low SVI group. CONCLUSIONS: The SVI has the potential to examine health care disparities in pediatric trauma patients and identify discrete at-risk target populations for preventative resources allocation and intervention. Future studies are necessary to determine the utility of this tool in additional pediatric cohorts.

Use of prehospital reverse shock index times Glasgow Coma Scale to identify children who require the most immediate trauma care.

BACKGROUND: Appropriate prehospital trauma triage ensures transport of children to facilities that provide specialized trauma care. There are currently no objective and generalizable scoring tool for emergency medical services to facilitate such decisions. An abnormal reverse shock index times Glasgow Coma Scale (rSIG), which is calculated using readily available parameters, has been shown to be associated with severely injured children. This study sought to determine if rSIG could be used in the prehospital setting to identify injured children who require the highest levels of care. METHODS: Patients (1-18 years old) transferred from the scene to a level 1 pediatric trauma center from 2010 to 2020 with complete prehospital and emergency department vital signs, and Glasgow Coma Scale (GCS) scores were included. Reverse shock index times GCS was calculated as previously described ((systolic blood pressure/heart rate) × GCS), and the following cutoffs were used: ≤13.1, ≤16.5, and ≤20.1 for 1- to 6-, 7- to 12-, and 13- to 18-year-old patients, respectively. Trauma activation level and clinical outcomes upon arrival to the pediatric trauma center were collected. RESULTS: There were 247 patients included in the analysis; 66.0% (163) had an abnormal prehospital rSIG. Patients with an abnormal rSIG had a higher rate of highest-level trauma activation compared with those with a normal rSIG (38.7% vs. 20.2%, p = 0.013). Patients with an abnormal prehospital rSIG also had higher rates of intubation (28.8% vs. 9.52%, p < 0.001), intracranial pressure monitor (9.20 vs. 1.19%, p = 0.032), need for blood (19.6% vs. 8.33%, p = 0.034), laparotomy (7.98% vs. 1.19%, p = 0.039), and intensive care unit admission (54.6% vs. 40.5%, p = 0.049). CONCLUSION: Reverse shock index times GCS may assist emergency medical service providers in early identification and triage of severely injured children. An abnormal rSIG in the emergency department is associated with higher rates of intubation, need for blood transfusion, intracranial pressure monitoring, laparotomy, and intensive care unit admission. Use of this metric may help to speed the identification, care, and treatment of any injured child. LEVEL OF EVIDENCE: Prognostic and Epidemiological; Level IV.

Use of reverse shock index times Glasgow coma scale (rSIG) to determine need for transfer of pediatric trauma patients to higher levels of care.

INTRODUCTION: Most children in the US live more than one hour from a Level 1 PTC. The Need For Trauma Intervention (NFTI) score was developed to assess trauma triage criteria and is dependent on whether someone requires one of six urgent interventions (NFTI+). We sought to determine if a novel scoring tool, rSIG, could predict NFTI and facilitate the transfer decision making process. METHODS: Children 1-18 years old transferred to our level 1 PTC from 2010 - 2020 with complete vital signs and Glasgow Coma Scale (GCS) score at the transferring facility were included. rSIG was calculated as previously described [(SBP/HR) x GCS], and the following cutoffs were used for each age group: ≤13.1, ≤16.5, and ≤20.1 for 1-6, 7-12, and 13-18 years, respectively. Clinical outcomes upon arrival to the PTC were collected to determine if patients met any NTFI criteria. RESULTS: A total of 456 patients met inclusion criteria. The proportion of patients with an abnormal rSIG was 60.1% (274) and 37.0% (169) were NFTI+. Patients with an abnormal rSIG had an odds ratio of 6.18 (95% CI: 3.90, 10.07), p < 0.001 of being NFTI+ compared to those with a normal rSIG. CONCLUSION: Children with an abnormal rSIG are more likely to be NFTI+ and require higher levels of care, indicating this scoring tool can identify pediatric trauma patients who may benefit from expedited transfer. Incorporating rSIG into initial evaluation and triage of traumatically injured children may expedite the transfer decision making process and limit delays in transport to a PTC.

The impact of the COVID-19 pandemic on pediatric firearm injuries in Colorado.

BACKGROUND: In 2019 firearm injuries surpassed automobile-related injuries as the leading cause of pediatric death in Colorado. In the spring of 2020, the COVID-19 pandemic led to community-level social, economic, and health impacts as well as changes to injury epidemiology. Thus, we sought to determine the impact of the COVID-19 pandemic on pediatric firearm injuries in Colorado. METHODS: We conducted a retrospective review of pediatric firearm injured patients (≤ 18-years-old) evaluated at three trauma centers in Colorado from 2018-2021. Patients were stratified into two groups based on the time of their firearm injury: pre- COVID injuries and post- COVID injuries. Group differences were examined using t-tests for continuous variables and Chi Squared or Fisher's exact tests for categorical variables. RESULTS: Overall, 343 firearm injuries occurred during the study period. There was a significant increase in firearm injuries as a proportion of overall pediatric ED trauma evaluations following the onset of the COVID-19 pandemic (pre COVID: 5.18/100 trauma evaluations; post COVID: 8.61/100 trauma evaluations, p<0.0001). Assaults were the most common injury intent seen both pre and post COVID (70.3% vs. 56.7%, respectively); however, unintentional injuries increased significantly from 10.3% to 22.5% (p = 0.004) following the onset of the pandemic. Additionally, the COVID-19 pandemic was associated with a 177% increase in unintentional injuries in adolescents. CONCLUSION: Pediatric firearm injuries, particularly unintentional injuries, increased significantly in Colorado following the onset of the COVID-19 pandemic. The substantial increase in unintentional injuries among adolescents highlights the necessity of multi-disciplinary approaches to limit or regulate their access to firearms. LEVEL OF EVIDENCE: Level III. STUDY TYPE: Retrospective.

National trends in pediatric firearm and automobile fatalities.

BACKGROUND: Successful public health policies and injury prevention efforts have reduced pediatric automobile fatalities across the United States. In 2019, firearm injuries exceeded motor vehicle crashes (MVC) as the leading cause of childhood death in Colorado. We sought to determine if similar trends exist nationally and if state gun laws impact firearm injury fatality rates. METHODS: Annual pediatric (≤19 years-old) fatality rates for firearm injuries and MVCs were obtained from the CDC WONDER database (1999-2020). State gun law scores were based on the 2014-2020 Gifford's Annual Gun Law Scorecard and strength was categorized by letter grades A-F. Poisson generalized linear mixed models were used to model fatality rates. Rates were estimated for multiple timepoints and compared between grade levels. RESULTS: In 1999, the national pediatric fatality rate for MVCs was 248% higher than firearm injuries (Incidence Rate Ratio (IRR) 95% Confidence Interval (CI): 2.25-2.73, p<0.0001). By 2020, the fatality rate for MVCs was 16% lower than that of firearm injuries (IRR 95% CI: 0.75- 0.93, p = 0.0014). For each increase in letter grade for gun law strength there was an 18% reduction in the firearm fatality rate (IRR 95%CI: 0.78-0.86, p<0.0001). States with the strongest gun laws (A) had a 55% lower firearm fatality rate compared to those with the weakest laws (F). CONCLUSION: Firearm injuries are the leading cause of death in pediatric patients across the United States. State gun law strength has a significant impact on pediatric firearm injury fatality rates. New public health policies, political action, media attention and safer guns are urgently needed to curb this national crisis. LEVEL OF EVIDENCE/STUDY TYPE: Level III, retrospective.

A precision-designed gastrostomy button securement device.

BACKGROUND: Gastrostomy buttons (g-buttons) are commonly placed in children to facilitate weight gain, correct nutritional deficiencies, and provide hydration and/or medication delivery. At our institution, parents are taught to place a gauze sponge under their child's g-button and secure it with strips of tape; however, the g-button still moves in the tract, which delays wound healing and leads to a variety of tract-related complications. We viewed this universal problem as a challenge and a prime opportunity for innovation. METHODS: In 2016, a pediatric surgeon and a team of graduate engineering students outlined the problem, created a list of design requirements, and began to iterate on a variety of device designs. RESULTS: Over 400 design ideas were iterated upon to various degrees. The first prototype was studied in a small clinical trial, in which 80% of caregivers reported satisfaction with the design, but 90% noted difficulty connecting the extension feeding tube. A second-generation prototype was developed, which included a reusable lid and disposable base layer. Third- generation prototypes added "edge-grippers" to facilitate attaching the extension tubing, plus pre-cut absorbent, sterile gauze pads to fit around the stem of the g-button. Finally, in 2020, the design was finalized with the addition of a childproof hinge between the lid and base layer. CONCLUSIONS: An intuitive g-button securement device was created to simplify daily gauze replacement, reduce tract-related complications, and lower the cost of care. A randomized controlled trial comparing the securement device to the "tic-tac-toe" dressing will begin in early 2022 with results available later this year.

Outcomes in Pediatric Trauma Patients Who Receive Blood Transfusion.

INTRODUCTION: Increased blood volumes, due to massive transfusion (MT), are known to be associated with both infectious and noninfectious adverse outcomes. The aim of this study was to assess the association between MT and outcomes in pediatric trauma patients, and, secondarily, determine if these outcomes are differential by age once MT is reached. METHODS: Pediatric patients (ages 1-18 y old) in the ACS pediatric Trauma Quality Improvement Program (TQIP) database (2015-2018) who received blood were included. Patients were stratified by MT status, which was defined as blood product volume of 40 mL/kg within 24 h of admission (MT+) and compared to children who received blood products but did not meet the MT threshold (MT-). Defined MT + patients were matched 1:1 to MT-patients via propensity score matching of characteristics before comparisons. Adjusted logistic regression was performed on univariably significant outcomes of interest. RESULTS: There were 2318 patients in the analytic cohort. Patients who received MT had higher rates of deep venous thrombosis (DVT) (2.5% versus 1.0%, P < 0.001), acute kidney injury (AKI) (1.5% versus 0.0%, P = 0.022), CLABSI (4.0% versus 2.0% P = 0.008), and severe sepsis (2.3% versus. 1.1%, P = 0.02). On logistic regression MT was an independent risk factor for these outcomes. There was no differential effect of MT on these outcomes based on age. CONCLUSIONS: Outcomes associated with blood transfusion in pediatric trauma patients are low overall, but rates of DVT, AKI, CLABSI, and sepsis are higher in those who receive MT+ with no differences based on age.

Palliative care reduces emergency room visits and total hospital days among patients with metastatic HPB and GI cancers.

Palliative care services (PCS) have improved quality of life for patients across various cancer subtypes. Minimal data exists regarding PCSfor metastatic hepatopancreaticobiliary (HPB) and gastrointestinal (GI) cancers. We assessed the impact of PCS on emergency department visits, hospital admissions, and survival among these patients. Patients with metastatic HPB and GI cancer referred to outpatient PCS between 2014 and 2018 at a single institution were included. We compared the demographics, outcomes, and end-of-life indicators between those who did and did not receive PCS. The study included 183 patients, with 118 (64.5%) having received PCS. There were no significant differences in age, gender, race, marital status, or insurance. Those receiving PCS were more likely to have colorectal cancer (p = 0.0082) and receive chemotherapy (p = 0.0098). On multivariate analysis, PCS was associated with fewer ED visits (p = 0.0319), hospital admissions (p = 0.0002), and total inpatient hospital days (p < 0.0001) per 30 days of life. Overall survival was greater among patients receiving PCS (HR: 0.65 (0.46-0.92)). Outpatient PCS for patients with metastatic HPB and GI cancer is associated with fewer emergency department visits, hospital admissions, and inpatient hospital days, and improved overall survival.

Individual and neighborhood level characteristics of pediatric firearm injuries presenting at trauma centers in Colorado.

BACKGROUND: Firearm injuries are the second leading cause of death among children and adolescents in the United States. In Colorado, firearm injuries have surpassed motor vehicle accidents as the leading cause of death in youth. Local research is necessary to characterize risk factors associated with pediatric firearm injuries. We sought to categorize demographics, neighborhood characteristics, and trends in pediatric firearm injuries in Colorado. METHODS: A review of pediatric firearm-injured patients (18 years or younger) evaluated at four trauma centers in Colorado from 2008 to 2019 was conducted. Clinical information, injury intent, and demographics were collected. Patient addresses were geocoded to census tracts to obtain neighborhood-level characteristics. Annual trends in firearm injury incidence per trauma evaluation were analyzed using regression modeling. RESULTS: There were 446 firearm injuries during the study period. The median age was 16 years, and 87.0% were male. Assault was the most common injury intent (64.6%), and 92.0% of patients were from metropolitan (rural-urban continuum code 1-3) areas. Neighborhoods associated with firearm injuries were characterized by lower median household income ($47,112 vs. $63,443, p < 0.001) and higher levels of poverty (19.1% vs. 9.4%, p < 0.001) compared with median state levels. There was a 14.0% increase in firearm injuries compared with overall trauma evaluations for each year in the study period (incidence rate ratio, 1.14; 95% confidence interval, 1.08-1.20; p < 0.001). CONCLUSION: The incidence of pediatric firearm injuries increased significantly from 2008 to 2019 compared with overall trauma evaluations in Colorado. Children and adolescents who live in more socially vulnerable neighborhoods are disproportionately impacted, and injury prevention resources should be focused on these communities. LEVEL OF EVIDENCE: Prognostic and Epidemiolgic; Level III.

Discreet Values of Shock Index Pediatric Age-Adjusted (SIPA) to Predict Intervention in Children With Blunt Organ Injuries.

INTRODUCTION: Elevated shock index pediatric age-adjusted (SIPA) has been shown to be associated with the need for both blood transfusion and intervention in pediatric patients with blunt liver and spleen injuries (BLSI). SIPA has traditionally been used as a binary value, which can be classified as elevated or normal, and this study aimed to assess if discreet values above SIPA cutoffs are associated with an increased probability of blood transfusion and failure of nonoperative management (NOM) in bluntly injured children. MATERIALS AND METHODS: Children aged 1-18 y with any BLSI admitted to a Level-1 pediatric trauma center between 2009 and 2020 were analyzed. Blood transfusion was defined as any transfusion within 24 h of arrival, and failure of NOM was defined as any abdominal operation or angioembolization procedure for hemorrhage control. The probabilities of receiving a blood transfusion or failure of NOM were calculated at different increments of 0.1. RESULTS: There were 493 patients included in the analysis. The odds of requiring blood transfusion increased by 1.67 (95% CI 1.49, 1.90) for each 0.1 unit increase of SIPA (P < 0.001). A similar trend was seen initially for the probability of failure of nonoperative management, but beyond a threshold, increasing values were not associated with failure of NOM. On subanalysis excluding patients with a head injury, increased 0.1 increments were associated with increased odds for both interventions. CONCLUSIONS: Discreet values above age-related SIPA cutoffs are correlated with higher probabilities of blood transfusion in pediatric patients with BLSI and failure of NOM in those without head injury. The use of discreet values may provide clinicians with more granular information about which patients require increased resources upon presentation.

Gastrostomy Tube Use in Pediatrics: A Systematic Review.

CONTEXT: Despite frequency of gastrostomy placement procedures in children, there remains considerable variability in preoperative work-up and procedural technique of gastrostomy placement and a paucity of literature regarding patient-centric outcomes. OBJECTIVES: This review summarizes existing literature and provides consensus-driven guidelines for patients throughout the enteral access decision-making process. DATA SOURCES: PubMed, Google Scholar, Medline, and Scopus. STUDY SELECTION: Included studies were identified through a combination of the search terms "gastrostomy," "g-tube," and "tube feeding" in children. DATA EXTRACTION: Relevant data, level of evidence, and risk of bias were extracted from included articles to guide formulation of consensus summaries of the evidence. Meta-analysis was conducted when data afforded a quantitative analysis. EVIDENCE REVIEW: Four themes were explored: preoperative nasogastric feeding tube trials, decision-making surrounding enteral access, the role of preoperative imaging, and gastrostomy insertion techniques. Guidelines were generated after evidence review with multidisciplinary stakeholder involvement adhering to GRADE methodology. RESULTS: Nearly 900 publications were reviewed, with 58 influencing final recommendations. In total, 17 recommendations are provided, including: (1) tTrial of home nasogastric feeding is safe and should be strongly considered before gastrostomy placement, especially for patients who are likely to learn to eat by mouth; (2) rRoutine contrast studies are not indicated before gastrostomy placement; and (3) lLaparoscopic placement is associated with the best safety profile. LIMITATIONS: Recommendations were generated almost exclusively from observational studies and expert opinion, with few studies describing direct comparisons between GT placement and prolonged nasogastric feeding tube trial. CONCLUSIONS: Additional patient- and family-centric evidence is needed to understand critical aspects of decision-making surrounding surgically placed enteral access devices for children.

Incidence of and risk factors for perioperative blood transfusion in infants undergoing index pediatric surgery procedures.

BACKGROUND: There is a paucity of data on the frequency of transfusion during pediatric surgery index cases and guidelines for pretransfusion testing, defined as type and screen and crossmatch testing, prior to operation are not standardized. This study aimed to determine the incidence of perioperative blood transfusions during index neonatal operations and identify risk factors associated with perioperative blood transfusion to determine which patients benefit from pretransfusion testing. METHODS: A retrospective review of infants who underwent index neonatal cases between 2013 and 2019 was performed. Data were collected for patients who underwent operations for Hirschsprung's disease, esophageal atresia/tracheoesophageal fistula (EA/TEF), biliary atresia, anorectal malformation, omphalocele, gastroschisis, duodenal atresia, congenital diaphragmatic hernia (non-ECMO) or pulmonary lobectomy. Infants under 6 months were included except in the case of lobectomy where infants up to 12 months were included. RESULTS: Analysis was performed on 420 patients. Twenty-five (6.0%) patients received perioperative blood transfusion. Patients who received perioperative transfusion most commonly underwent EA/TEF repair. Patients who received perioperative transfusion had higher rates of structural heart disease (52.0% vs 17.7%, p<0.001), preoperative transfusion (48.0% vs 8.9%, p<0.001), and prematurity (52.0% vs 25.6%, p = 0.005). Presence of all three risk factors resulted in a 48% probability of requiring perioperative transfusion. CONCLUSIONS: Blood transfusion during the perioperative period of neonatal index operations is rare. Factors associated with increased risk of perioperative transfusion include prematurity, structural heart disease, and history of previous blood transfusion. LEVEL OF EVIDENCE: III.

Improved identification of severely injured pediatric trauma patients using reverse shock index multiplied by Glasgow Coma Scale.

BACKGROUND: The shock index pediatric age-adjusted (SIPA) predicts the need for increased resources and mortality among pediatric trauma patients without incorporating neurological status. A new scoring tool, rSIG, which is the reverse shock index (rSI) multiplied by the Glasgow Coma Scale (GCS), has been proven superior at predicting outcomes in adult trauma patients and mortality in pediatric patients compared with traditional scoring systems. We sought to compare the accuracy of rSIG to Shock Index (SI) and SIPA in predicting the need for early interventions in civilian pediatric trauma patients. METHODS: Patients (aged 1-18 years) in the 2014 to 2018 Pediatric Trauma Quality Improvement Program database with complete heart rate, systolic blood pressure, and total GCS were included. Optimal cut points of rSIG were calculated for predicting blood transfusion within 4 hours, intubation, intracranial pressure monitoring, and intensive care unit admission. From the optimal thresholds, sensitivity, specificity, and area under the curve were calculated from receiver operating characteristics analyses to predict each outcome and compared with SI and SIPA. RESULTS: A total of 604,931 patients with a mean age of 11.1 years old were included. A minority of patients had a penetrating injury mechanism (5.6%) and the mean Injury Severity Score was 7.6. The mean SI and rSIG scores were 0.85 and 18.6, respectively. Reverse shock index multiplied by Glasgow Coma Scale performed better than SI and SIPA at predicting early trauma outcomes for the overall population, regardless of age. CONCLUSION: Reverse shock index multiplied by Glasgow Coma Scale outperformed SI and SIPA in the early identification of traumatically injured children at risk for early interventions, such as blood transfusion within 4 hours, intubation, intracranial pressure monitoring, and intensive care unit admission. Reverse shock index multiplied by Glasgow Coma Scale adds neurological status in initial patient assessment and may be used as a bedside triage tool to rapidly identify pediatric patients who will likely require early intervention and higher levels of care. LEVEL OF EVIDENCE: Prognostic, level III.

Pediatric cardiac and great vessel injuries: Recent experience at two pediatric trauma centers.

BACKGROUND: Cardiac injuries are rare in pediatric trauma patients and data regarding this type of injury is limited. There is even less data on traumatic great vessel injuries. This study sought to examine and summarize our recent experience at two pediatric trauma centers, which serve a major metropolitan area and large geographic region. METHODS: This is a retrospective review of pediatric (<18 years) patients who sustained cardiac or great vessel injuries and were managed at a Level 1 or Level 2 pediatric trauma center between January 1, 2010 and June 30, 2020. Demographic and clinical characteristics were compared using two-sample t-tests, Wilcoxon Rank-Sum tests, Fisher's exact tests and chi-squared tests for continuous, non-normally distributed continuous, and categorical variables, respectively. RESULTS: A total of 53 patients sustained cardiac and/or great vessel injuries. Of these, 37 (70%) sustained cardiac, 9 (17%) sustained great vessel, and 7 (13%) sustained both types of injuries. The median age was 14.9 years and 74% (n = 39) were male. The median injury severity score (ISS) was 36.0 and the injury mechanism was blunt in 31 (58%) patients. The most common cardiac and great vessel injury locations were left ventricle (n = 9) and thoracic aorta (n = 11), respectively. The overall mortality rate was 53% (n = 28). Mortality was highest among those who sustained great vessel injuries (89%). CONCLUSIONS: There is substantial heterogeneity in cardiac and great vessel injuries. Regardless, they are highly morbid and lethal, despite aggressive surgical and catheter-based interventions.
