Pediatric Trauma Recidivism: A Statewide Risk Factor Analysis of the Maryland Health Services Cost Review Commission (HSCRC).

BACKGROUND: National estimates suggest pediatric trauma recidivism is uncommon but are limited by short follow up and narrow ascertainment. We aimed to quantify the long-term frequency of trauma recidivism in a statewide pediatric population and identify risk factors for re-injury. METHODS: The Maryland Health Services Cost Review Commission Dataset was queried for 0-19-year-old patients with emergency department or inpatient encounters for traumatic injuries between 2013 and 2019. We measured trauma recidivism by identifying patients with any subsequent presentation for a new traumatic injury. Univariate and multivariable regressions were used to estimate associations of patient and injury characteristics with any recidivism and inpatient recidivism. RESULTS: Of 574,472 patients with at least one injury encounter, 29.6% experienced trauma recidivism. Age ≤2 years, public insurance, and self-inflicted injuries were associated with recidivism regardless of index treatment setting. Of those with index emergency department presentations 0.06% represented with an injury requiring inpatient admission; unique risk factors for ED-to-inpatient recidivism were age >10 years (aOR 1.61), cyclist (aOR 1.31) or burn (aOR 1.39) mechanisms, child abuse (aOR 1.27), and assault (aOR 1.43). Among patients with at least one inpatient encounter, 6.3% experienced another inpatient trauma admission, 3.4% of which were fatal. Unique risk factors for inpatient-to-inpatient recidivism were firearm (aOR 2.48) and motor vehicle/transportation (aOR 1.62) mechanisms of injury (all p < 0.05). CONCLUSIONS: Pediatric trauma recidivism is more common and morbid than previously estimated, and risk factors for repeat injury differ by treatment setting. Demographic and injury characteristics may help develop and target setting-specific interventions. LEVEL OF EVIDENCE: III (Retrospective Comparative Study).

Management of Gastroschisis: Timing of Delivery, Antibiotic Usage, and Closure Considerations (A Systematic Review From the American Pediatric Surgical Association Outcomes & Evidence Based Practice Committee).

BACKGROUND: No consensus exists for the initial management of infants with gastroschisis. METHODS: The American Pediatric Surgical Association (APSA) Outcomes and Evidenced-based Practice Committee (OEBPC) developed three a priori questions about gastroschisis for a qualitative systematic review. We reviewed English-language publications between January 1, 1970, and December 31, 2019. This project describes the findings of a systematic review of the three questions regarding: 1) optimal delivery timing, 2) antibiotic use, and 3) closure considerations. RESULTS: 1339 articles were screened for eligibility; 92 manuscripts were selected and reviewed. The included studies had a Level of Evidence that ranged from 2 to 4 and recommendation Grades B-D. Twenty-eight addressed optimal timing of delivery, 5 pertained to antibiotic use, and 59 discussed closure considerations (Figure 1). Delivery after 37 weeks post-conceptual age is considered optimal. Prophylactic antibiotics covering skin flora are adequate to reduce infection risk until definitive closure. Studies support primary fascial repair, without staged silo reduction, when abdominal domain and hemodynamics permit. A sutureless repair is safe, effective, and does not delay feeding or extend length of stay. Sedation and intubation are not routinely required for a sutureless closure. CONCLUSIONS: Despite the large number of studies addressing the above-mentioned facets of gastroschisis management, the data quality is poor. A wide variation in gastroschisis management was documented, indicating a need for high quality RCTs to provide an evidence-based approach when caring for these infants. TYPE OF STUDY: Qualitative systematic review of Level 1-4 studies.

Delphi Process for Validation of Fluid Treatment Algorithm for Critically Ill Pediatric Trauma Patients.

INTRODUCTION: While intravenous fluid therapy is essential to re-establishing volume status in children who have experienced trauma, aggressive resuscitation can lead to various complications. There remains a lack of consensus on whether pediatric trauma patients will benefit from a liberal or restrictive crystalloid resuscitation approach and how to optimally identify and transition between fluid phases. METHODS: A panel was comprised of physicians with expertise in pediatric trauma, critical care, and emergency medicine. A three-round Delphi process was conducted via an online survey, with each round being followed by a live video conference. Experts agreed or disagreed with each aspect of the proposed fluid management algorithm on a five-level Likert scale. The group opinion level defined an algorithm parameter's acceptance or rejection with greater than 75% agreement resulting in acceptance and greater than 50% disagreement resulting in rejection. The remaining were discussed and re-presented in the next round. RESULTS: Fourteen experts from five Level 1 pediatric trauma centers representing three subspecialties were included. Responses were received from 13/14 participants (93%). In round 1, 64% of the parameters were accepted, while the remaining 36% were discussed and re-presented. In round 2, 90% of the parameters were accepted. Following round 3, there was 100% acceptance by all the experts on the revised and final version of the algorithm. CONCLUSIONS: We present a validated algorithm for intavenous fluid management in pediatric trauma patients that focuses on the de-escalation of fluids. Focusing on this time point of fluid therapy will help minimize iatrogenic complications of crystalloid fluids within this patient population.

Social Vulnerability and Firearm Violence: Geospatial Analysis of 5 US Cities.

BACKGROUND: Firearm violence is now endemic to certain US neighborhoods. Understanding factors that impact a neighborhood's susceptibility to firearm violence is crucial for prevention. Using a nationally standardized measure to characterize community-level firearm violence risk has not been broadly studied but could enhance prevention efforts. Thus, we sought to examine the association between firearm violence and the social, structural, and geospatial determinants of health, as defined by the Social Vulnerability Index (SVI). STUDY DESIGN: In this cross-sectional study, we merged 2018 SVI data on census tract with shooting incidents between 2015 and 2021 from Baltimore, Chicago, Los Angeles, New York City, and Philadelphia. We used negative binomial regression to associate the SVI with shooting incidents per 1,000 people in a census tract. Moran's I statistics and spatial lag models were used for geospatial analysis. RESULTS: We evaluated 71,296 shooting incidents across 4,415 census tracts. Fifty-five percent of shootings occurred in 9.4% of census tracts. In all cities combined, a decile rise in SVI resulted in a 37% increase in shooting incidents (p < 0.001). A similar relationship existed in each city: 30% increase in Baltimore (p < 0.001), 50% in Chicago (p < 0.001), 28% in Los Angeles (p < 0.001), 34% in New York City (p < 0.001), and 41% in Philadelphia (p < 0.001). Shootings were highly clustered within the most vulnerable neighborhoods. CONCLUSIONS: In 5 major US cities, firearm violence was concentrated in neighborhoods with high social vulnerability. A tool such as the SVI could be used to inform prevention efforts by directing resources to communities most in need and identifying factors on which to focus these programs and policies.

When public health crises collide: 5 years of pediatric firearm injury prevention opportunities.

Objectives: Prior publications on pediatric firearm-related injuries have emphasized significant social disparities. The pandemic has heightened a variety of these societal stresses. We sought to evaluate how we must now adapt our injury prevention strategies. Patients and methods: Firearm-related injuries in children 15 years old and under at five urban level 1 trauma centers between January 2016 and December 2020 were retrospectively reviewed. Age, gender, race/ethnicity, Injury Severity Score, situation, timing of injury around school/curfew, and mortality were evaluated. Medical examiner data identified additional deaths. Results: There were 615 injuries identified including 67 from the medical examiner. Overall, 80.2% were male with median age of 14 years (range 0-15; IQR 12-15). Black children comprised 77.2% of injured children while only representing 36% of local schools. Community violence (intentional interpersonal or bystander) injuries were 67.2% of the cohort; 7.8% were negligent discharges; and 2.6% suicide. Median age for intentional interpersonal injuries was 14 years (IQR 14-15) compared with 12 years (IQR 6-14, p<0.001) for negligent discharges. Far more injuries were seen in the summer after the stay-at-home order (p<0.001). Community violence and negligent discharges increased in 2020 (p=0.004 and p=0.04, respectively). Annual suicides also increased linearly (p=0.006). 5.5% of injuries were during school; 56.7% after school or during non-school days; and 34.3% were after legal curfew. Mortality rate was 21.3%. Conclusions: Pediatric firearm-related injuries have increased during the past 5 years. Prevention strategies have not been effective during this time interval. Prevention opportunities were identified specifically in the preteenage years to address interpersonal de-escalation training, safe handling/storage, and suicide mitigation. Efforts directed at those most vulnerable need to be reconsidered and examined for their utility and effectiveness. Level of evidence: Level III; epidemiological study type.

A novel machine-learning tool to identify community risk for firearm violence: The Firearm Violence Vulnerability Index.

BACKGROUND: Firearm violence in the United States is a public health crisis, but accessing accurate firearm assault data to inform prevention strategies is a challenge. Vulnerability indices have been used in other fields to better characterize and identify at-risk populations during crises, but no tool currently exists to predict where rates of firearm violence are highest. We sought to develop and validate a novel machine-learning algorithm, the Firearm Violence Vulnerability Index (FVVI), to forecast community risk for shooting incidents, fill data gaps, and enhance prevention efforts. METHODS: Open-access 2015 to 2022 fatal and nonfatal shooting incident data from Baltimore, Boston, Chicago, Cincinnati, Los Angeles, New York City, Philadelphia, and Rochester were merged on census tract with 30 population characteristics derived from the 2020 American Community Survey. The data set was split into training (80%) and validation (20%) sets; Chicago data were withheld for an unseen test set. XGBoost, a decision tree-based machine-learning algorithm, was used to construct the FVVI model, which predicts shooting incident rates within urban census tracts. RESULTS: A total of 64,909 shooting incidents in 3,962 census tracts were used to build the model; 14,898 shooting incidents in 766 census tracts were in the test set. Historical third grade math scores and having a parent jailed during childhood were population characteristics exhibiting the greatest impact on FVVI's decision making. The model had strong predictive power in the test set, with a goodness of fit ( D2 ) of 0.77. CONCLUSION: The Firearm Violence Vulnerability Index accurately predicts firearm violence in urban communities at a granular geographic level based solely on population characteristics. The Firearm Violence Vulnerability Index can fill gaps in currently available firearm violence data while helping to geographically target and identify social or environmental areas of focus for prevention programs. Dissemination of this standardized risk tool could also enhance firearm violence research and resource allocation. LEVEL OF EVIDENCE: Prognostic and Epidemiological; Level IV.

Social Vulnerability Index is strongly associated with urban pediatric firearm violence: An analysis of five major US cities.

BACKGROUND: Firearm-related injury in children is a public health crisis. The Social Vulnerability Index (SVI) identifies communities at risk for adverse effects due to natural or human-caused crises. We sought to determine if SVI was associated with pediatric firearm-related injury and thus could assist in prevention planning. METHODS: The Centers for Disease Control and Prevention's 2018 SVI data were merged on census tract with 2015 to 2022 open-access shooting incident data in children 19 years or younger from Baltimore, Chicago, Los Angeles, New York City, and Philadelphia. Regression analyses were performed to uncover associations between firearm violence, SVI, SVI themes, and social factors at the census tract level. RESULTS: Of 11,654 shooting incidents involving children, 52% occurred in just 6.7% of census tracts, which were on average in the highest quartile of SVI. A decile increase in SVI was associated with a 45% increase in pediatric firearm-related injury in all cities combined (incidence rate ratio, 1.45; 95% confidence interval, 1.41-1.49; p < 0.001). A similar relationship was found in each city: 30% in Baltimore, 51% in Chicago, 29% in Los Angeles, 37% in New York City, and 35% in Philadelphia (all p < 0.001). Socioeconomic status and household composition were SVI themes positively associated with shootings in children, as well as the social factors below poverty, lacking a high school diploma, civilian with a disability, single-parent household, minority, and no vehicle access. Living in areas with multi-unit structures, populations 17 years or younger, and speaking English less than well were negatively associated. CONCLUSION: Geospatial disparities exist in pediatric firearm-related injury and are significantly associated with neighborhood vulnerability. We demonstrate a strong association between SVI and pediatric shooting incidents in multiple major US cities. Social Vulnerability Index can help identify social and structural factors, as well as geographic areas, to assist in developing meaningful and targeted intervention and prevention efforts. LEVEL OF EVIDENCE: Prognostic and Epidemiological; Level III.

Rising Mortality in Pediatric Self-Inflicted Firearm Trauma Associated With Distinct Anatomic Injury.

INTRODUCTION: Self-inflicted injuries are the second leading cause of pediatric (10-18 y old) mortality. Self-inflicted firearm trauma (SIFT) was responsible for up to half of these deaths in certain age groups. We hypothesized that SIFT prevalence has increased and is associated with specific demographics, injury patterns, and outcomes. MATERIALS AND METHODS: Data were abstracted from the 2007-2018 American College of Surgeons (ACS) Trauma Quality Programs Participant Use Files (TQP-PUF). Pediatric (1-17 yold) victims of firearm violence were eligible. Age, race, gender, anatomic region, and intent were abstracted. Variables were analyzed using chi-squared tests, t-tests, and single-variate linear regression models. Temporal trends were analyzed using ANCOVA tests. Multivariate logistic regressions were conducted to identify factors influencing mortality. Significance was P < 0.05. RESULTS: There were 41,239 pediatric firearm trauma patients (SIFT: 5.5% [n = 2272]). SIFT incidence increased over the 12-y period (2007 (n = 67) versus 2018 (n = 232), P < 0.05). SIFT was significantly associated with Caucasian race, 67% (n = 1537), teenagers, 90% (n = 2056), male gender, 87% (n = 1978), and a higher median injury severity score (ISS) than other intents of injury (SIFT: 20.0 (IQR: 9.0, 25.0) versus other: 9.0 (IQR: 1.0-13.0), P < 0.001). The SIFT mortality rate was 44% (n = 1005). On multivariate regression head gunshot wounds (OR: 21.1, 95% C.I.: 9.9-45.2, P = 0.001), and ISS (OR:1.1, 95% C.I.: 1.1-1.1, P = 0.001) were significantly associated with mortality. Compared to other intents, SIFT mortality rates increased at a higher annual rate (P < 0.001). CONCLUSIONS: Comprehensive local and federal policy changes to reduce firearms access and increase pediatric mental health support may mitigate these injuries.

Thoracoscopy versus thoracotomy for esophageal atresia and tracheoesophageal fistula: Outcomes from the Midwest Pediatric Surgery Consortium.

BACKGROUND/PURPOSE: Controversy persists regarding the ideal surgical approach for repair of esophageal atresia with tracheoesophageal fistula (EA/TEF). We examined complications and outcomes of infants undergoing thoracoscopy and thoracotomy for repair of Type C EA/TEF using propensity score-based overlap weights to minimize the effects of selection bias. METHODS: Secondary analysis of two databases from multicenter retrospective and prospective studies examining outcomes of infants with proximal EA and distal TEF who underwent repair at 11 institutions was performed based on surgical approach. Regression analysis using propensity score-based overlap weights was utilized to evaluate outcomes of patients undergoing thoracotomy or thoracoscopy for Type C EA/TEF repair. RESULTS: Of 504 patients included, 448 (89%) underwent thoracotomy and 56 (11%) thoracoscopy. Patients undergoing thoracoscopy were more likely to be full term (37.9 vs. 36.3 weeks estimated gestational age, p < 0.001), have a higher weight at operative repair (2.9 vs. 2.6 kg, p < 0.001), and less likely to have congenital heart disease (16% vs. 39%, p < 0.001). Postoperative stricture rate did not differ by approach, 29 (52%) thoracoscopy and 198 (44%) thoracotomy (p = 0.42). Similarly, there was no significant difference in time from surgery to stricture formation (p > 0.26). Regression analysis using propensity score-based overlap weighting found no significant difference in the odds of vocal cord paresis or paralysis (OR 1.087 p = 0.885), odds of anastomotic leak (OR 1.683 p = 0.123), the hazard of time to anastomotic stricture (HR 1.204 p = 0.378), or the number of dilations (IRR 1.182 p = 0.519) between thoracoscopy and thoracotomy. CONCLUSION: Infants undergoing thoracoscopic repair of Type C EA/TEF are more commonly full term, with higher weight at repair, and without congenital heart disease as compared to infants repaired via thoracotomy. Utilizing propensity score-based overlap weighting to minimize the effects of selection bias, we found no significant difference in complications based on surgical approach. However, our study may be underpowered to detect such outcome differences owing to the small number of infants undergoing thoracoscopic repair. LEVEL OF EVIDENCE: Level III.

Improved Kasai Hepatoportoenterostomy Outcomes After Implementation of a Dedicated Biliary Atresia Team.

It can be difficult or impractical to refer all biliary atresia (BA) patients to high-volume centers. Our hypothesis was that a low volume center could improve outcomes with implementation of a dedicated multidisciplinary BA team. We conducted a retrospective study of patients with BA who underwent hepatic portoenterostomy at our institution from 2003 to 2020, before and after the development of a dedicated BA team. Ten consecutive patients with BA were identified following the establishment of a dedicated BA team. Since the establishment of the BA team, total bilirubin (TB) clearance (TB < 2 mg/dL) achieved by 3 and 6 months has been 60% and 60%, respectively, and survival of the native liver (SNL) at 1 and 2 years post HPE at 90% and 86%, respectively. Outcomes were markedly improved after the team was established. A dedicated BA team prioritizing communication and expeditious workup can improve outcomes at a low volume center.

Use of shear wave elastography for the diagnosis and follow-up of biliary atresia: A meta-analysis.

BACKGROUND: Timely differentiation of biliary atresia (BA) from other infantile cholestatic diseases can impact patient outcomes. Additionally, non-invasive staging of fibrosis after Kasai hepatoportoenterostomy has not been widely standardized. Shear wave elastography is an ultrasound modality that detects changes in tissue stiffness. The authors propose that the utility of elastography in BA can be elucidated through meta-analysis of existing studies. AIM: To assess the utility of elastography in: (1) BA diagnosis, and (2) post-Kasai fibrosis surveillance. METHODS: A literature search identified articles that evaluated elastography for BA diagnosis and for post-Kasai follow-up. Twenty studies met criteria for meta-analysis: Eleven for diagnosis and nine for follow-up post-Kasai. Estimated diagnostic odds ratio (DOR), sensitivity, and specificity of elastography were calculated through a random-effects model using Meta-DiSc software. RESULTS: Mean liver stiffness in BA infants at diagnosis was significantly higher than in non-BA, with overall DOR 24.61, sensitivity 83%, and specificity 79%. Post-Kasai, mean liver stiffness was significantly higher in BA patients with varices than in patients without, with DOR 16.36, sensitivity 85%, and specificity 76%. Elastography differentiated stage F4 fibrosis from F0-F3 with DOR of 70.03, sensitivity 96%, and specificity 89%. Elastography also differentiated F3-F4 fibrosis from F0-F2 with DOR of 24.68, sensitivity 85%, and specificity 81%. CONCLUSION: Elastography has potential as a non-invasive modality for BA diagnosis and surveillance post-Kasai. This paper's limitations include inter-study method heterogeneity and small sample sizes. Future, standardized, multi-center studies are recommended.

Demographic and Regional Factors Associated With Reporting Homicides of Transgender People in the United States.

INTRODUCTION: The American Medical Association recently declared homicides of transgender individuals an epidemic. However, transgender homicide victims are often classified as nontransgender. Our objective was to describe existing data and coding of trans (i.e., transgender) victims and to examine the risk factors for homicides of trans people relative to nontrans people across the United States. METHODS: A retrospective review of the Centers for Disease Control and Prevention's National Violent Death Reporting System for the years 2003-2018 identified victims defined as transgender either through the "transgender" variable or narrative reports. Fisher's exact tests and logistic regression models were run to compare the demographics of trans victims to those not identified as trans. RESULTS: Of the 147 transgender victims identified, 14.4% were incorrectly coded as nontrans despite clear indication of trans status in the narrative description, and 6% were coded as hate crimes. Relative to nontrans victims, trans victims were more frequently Black (54.4% versus 40.7%, P = 0.001), had a mental health condition (26.5% versus 11.3%, P < 0.001), or reported being a sex worker (9.5% versus 0.2%, P < 0.001). There were disproportionately few homicides of transgender people in the South (13.6% of trans victims versus 29.1% of nontrans victims, P < 0.001). Conversely, the West and Midwest accounted for a higher-than-expected proportion of trans victims relative to nontrans victims (23.1% of trans victims versus 16.2% of nontrans victims, P = 0.03; 24.5% of trans victims versus 16.8% of nontrans victims, P = 0.02, respectively). CONCLUSIONS: Though the murder of transgender individuals is a known public health crisis, inconsistencies still exist in the assessment and reporting of transgender status. Further, these individuals were more likely to have multiple distinct vulnerabilities. These findings provide important information for injury and violence prevention researchers to improve reporting of transgender status in the medical record and local trauma registries.

Derivation and validation of an improved pediatric shock index for predicting need for early intervention and outcomes in pediatric trauma.

BACKGROUND: Shock index, pediatric age adjusted (SIPA), has been widely applied in pediatric trauma but has limited precision because of the reference ranges used in its derivation. We hypothesized that a pediatric shock index (PSI) equation based on age-based vital signs would outperform SIPA. METHODS: A retrospective cohort of trauma patients aged 1 to 18 years from Trauma Quality Programs - Participant Use File 2010 to 2018 was performed. A random 70% training subset was used to derive Youden index-optimizing shock index (SI) cutoffs by age for blood transfusion within 4 hours. We used linear regression to derive equations representing the PSI cutoff for children 12 years or younger and 13 years or older. For children 13 years or older, the well-established SI of 0.9 remained optimal, consistent with SIPA and other indices. For children 12 years or younger in the 30% validation subset, we compared our age-based PSI to SIPA as predictors of early transfusion, mortality, pediatric intensive care unit admission, and injury severity score of ≥25. For bedside use, a simplified "rapid" pediatric shock index (rPSI) equation was also derived and compared with SIPA. RESULTS: A total of 439,699 patients aged 1 to 12 years met the inclusion criteria with 2,718 (1.3% of those with available outcome data) requiring transfusion within 4 hours of presentation. In the validation set, positive predictive values for early transfusion were higher for PSI (8.3%; 95% confidence interval [CI], 7.5-9.1%) and rPSI (6.3%; 95% CI, 5.7-6.9%) than SIPA (4.3%; 95% CI, 3.9-4.7%). For early transfusion, negative predictive values for both PSI (99.3%; 95% CI, 99.2-99.3%) and rPSI (99.3%; 95% CI, 99.2-99.4%) were similar to SIPA (99.4%; 95% CI, 99.3-99.4%). CONCLUSION: We derived the PSI and rPSI for use in pediatric trauma using empiric, age-based SI cutoffs. The PSI and rPSI achieved higher positive predictive values and similar negative predictive values to SIPA in predicting the need for early blood transfusion and mortality. LEVEL OF EVIDENCE: Prognostic/Epidemiological; level III.

Association of Economic Recession and Social Distancing With Pediatric Non-accidental Trauma During COVID-19.

INTRODUCTION: There has been concern that the incidence of non-accidental trauma (NAT) cases in children would rise during the COVID-19 pandemic due to the combination of social isolation and economic depression. Our goal was to evaluate NAT incidence and severity during the pandemic across multiple US cities. METHODS: Multi-institutional, retrospective cohort study comparing NAT rates in children <18 y old during the COVID-19 pandemic (March-August 2020) with a recent historical data (January 2015-February 2020) and during a previous economic recession (January 2007-December 2011) at level 1 Pediatric Trauma Centers. Comparisons were made in local and national macroeconomic indicators. RESULTS: Overall rates of NAT during March-August 2020 did not increase compared to historical data (P = 0.8). Severity of injuries did not increase during the pandemic as measured by Glasgow Coma Scale (GCS) (P = 0.97) or mortality (P = 0.7), but Injury Severity Score (ISS) slightly decreased (P = 0.018). Racial differences between time periods were seen, with increased proportions of NAT occurring in African-Americans during the pandemic (P < 0.001). NAT rates over time had low correlation (r = 0.32) with historical averages, suggesting a difference from previous years. Older children (≥3 y) had increased NAT rates during the pandemic. Overall NAT rates had low inverse correlation with unemployment (r = -0.37) and moderate inverse correlation with the stock market (r = -0.6). Significant variation between sites was observed. CONCLUSIONS: Overall NAT rates in children did not increase during the COVID-19 pandemic, but rates were highly variable by site and increases were seen in African-Americans and older children. Further studies are warranted to explore local influences on NAT rates.

Acid suppression duration does not alter anastomotic stricture rates after esophageal atresia with distal tracheoesophageal fistula repair: A prospective multi-institutional cohort study.

INTRODUCTION: Anastomotic stricture is the most common complication after esophageal atresia (EA) repair. We sought to determine if postoperative acid suppression is associated with reduced stricture formation. METHODS: A prospective, multi-institutional cohort study of infants undergoing primary EA repair from 2016 to 2020 was performed. Landmark analysis and multivariate Cox regression were used to explore if initial duration of acid suppression was associated with stricture formation at hospital discharge (DC), 3-, 6-, and 9-months postoperatively. RESULTS: Of 156 patients, 79 (51%) developed strictures and 60 (76%) strictures occurred within three months following repair. Acid suppression was used in 141 patients (90%). Landmark analysis showed acid suppression was not associated with reduction in initial stricture formation at DC, 3-, 6- and 9-months, respectively (p = 0.19-0.95). Multivariate regression demonstrated use of a transanastomotic tube was significantly associated with stricture formation at DC (Hazard Ratio (HR) = 2.21 (95% CI 1.24-3.95, p<0.01) and 3-months (HR 5.31, 95% CI 1.65-17.16, p<0.01). There was no association between acid suppression duration and stricture formation. CONCLUSION: No association between the duration of postoperative acid suppression and anastomotic stricture was observed. Transanastomotic tube use increased the risk of anastomotic strictures at hospital discharge and 3 months after repair.

Alternative shock index cutoffs for pediatric patients outperform the Shock Index Pediatric Age-adjusted (SIPA) on strength of association with adverse outcomes in pediatric trauma patients.

BACKGROUND: The shock index is a tool for evaluating critically ill patients that is defined as the ratio of their heart rate divided by systolic blood pressure. The SI is associated with outcomes in adult trauma patients. The Shock Index Pediatric Age-adjusted was developed as a pediatric-specific tool to account for the physiologic differences of children of varying ages. There is growing interest in Shock Index Pediatric Age-adjusted, which is associated with adverse outcomes in pediatric trauma. We hypothesized that alternative shock index cutoffs based on the Advanced Trauma Life Support or the Pediatric Advanced Life Support vital sign reference ranges would outperform Shock Index Pediatric Age-adjusted. METHODS: We analyzed a retrospective cohort of pediatric trauma patients (age 1 to 16 years old) in the American College of Surgeons Trauma Quality Programs Participant Use File from 2010 to 2018. The primary outcome measure was in-hospital mortality. The Shock Index Pediatric Age-adjusted was compared to an Advanced Trauma Life Support-based and a Pediatric Advanced Life Support-based shock index cutoff system. Our findings were subsequently confirmed with a separate, internal validation data set. RESULTS: A total of 598,830 Trauma Quality Programs Participant Use File patients were included, 0.9% (n = 5,471) of whom died. For mortality, the Advanced Trauma Life Support-based system yielded the highest positive predictive value (15.8%; 95% confidence interval 15.0%-16.7%) compared with the Pediatric Advanced Life Support-based system (4.3%; 95% confidence interval 4.1%-4.5%). Both the Advanced Trauma Life Support-based and Pediatric Advanced Life Support-based systems achieved higher positive predictive values compared to Shock Index Pediatric Age-adjusted (2.6%; 95% confidence interval 2.5%-2.7%). The negative predictive values were not clinically different. Our findings were validated using a separate internal trauma database, in which the positive predictive value for mortality of the Advanced Trauma Life Support-based system was significantly higher than Shock Index Pediatric Age-adjusted (18.2% [95% confidence interval: 8.2%-32.7%] vs 2.9% [95% confidence interval: 1.6%-5.0%], P < .05). CONCLUSION: Advanced Trauma Life Support and Pediatric Advanced Life Support-based shock index cutoffs achieved higher positive predictive values and similar negative predictive values compared to Shock Index Pediatric Age-adjusted for adverse outcomes in pediatric trauma.

Mortality and PICU Hospitalization Among Pediatric Gunshot Wound Victims in Chicago.

Firearm injury accounts for significant morbidity with high mortality among children admitted to the PICU. Understanding risk factors for PICU admission is an important step toward developing prevention and intervention strategies to minimize the burden of pediatric gunshot wound (GSW) injury. OBJECTIVES: The primary objective of this study was to characterize outcomes and the likelihood of PICU admission among children with GSWs. DESIGN SETTING AND PARTICIPANTS: Retrospective cohort study of GSW patients 0-18 years old evaluated at the University of Chicago Comer Children's Hospital Pediatric Trauma Center from 2010 to 2017. MAIN OUTCOMES AND MEASURES: Demographic and injury severity measures were acquired from an institutional database. We describe mortality and hospitalization characteristics for the cohort. We used logistic regression models to test the association between PICU admission and patient characteristics. RESULTS: During the 8-year study period, 294 children experienced GSWs. We did not observe trends in overall mortality over time, but mortality for children with GSWs was higher than all-cause PICU mortality. Children 0-6 years old experienced longer hospitalizations compared with children 13-16 years old (5 vs 3 d; p = 0.04) and greater frequency of PICU admission (83.3% vs 52.9%; p = 0.001). Adjusting for severity of illness, children less than 7 years old were four-fold more likely to be admitted to the PICU than children 13-16 years old (aOR range, 3.9-4.6). CONCLUSIONS AND RELEVANCE: Despite declines in pediatric firearm mortality across the United States, mortality did not decrease over time in our cohort and was higher than all-cause PICU mortality. Younger children with GSWs experience longer hospitalizations and require PICU care more often than older children. Our findings suggest that the youngest victims of firearm-related injury may be particularly at-risk of the long-term sequelae of critical illness and injury.
