BACKGROUND: Injuries, the leading cause of death in children 1-17 years old, are often preventable. Injury patterns are impacted by changes in the child's environment, shifts in supervision, and caregiver stressors. The objective of this study was to evaluate the incidence and proportion of injuries, mechanisms, and severity seen in Pediatric Emergency Departments (PEDs) during the COVID-19 pandemic. METHODS: This multicenter, cross-sectional study from January 2019 through December 2020 examined visits to 40 PEDs for children < 18 years old. Injury was defined by at least one International Classification of Disease-10th revision (ICD-10) code for bodily injury (S00-T78). The main study outcomes were total and proportion of PED injury-related visits compared to all visits in March through December 2020 and to the same months in 2019. Weekly injury visits as a percentage of total PED visits were calculated for all weeks between January 2019 and December 2020. RESULTS: The study included 741,418 PED visits for injuries pre-COVID-19 pandemic (2019) and during the COVID-19 pandemic (2020). Overall PED visits from all causes decreased 27.4% in March to December 2020 compared to the same time frame in 2019; however, the proportion of injury-related PED visits in 2020 increased by 37.7%. In 2020, injured children were younger (median age 6.31 years vs 7.31 in 2019), more commonly White (54% vs 50%, p < 0.001), non-Hispanic (72% vs 69%, p < 0.001) and had private insurance (35% vs 32%, p < 0.001). Injury hospitalizations increased 2.2% (p < 0.001) and deaths increased 0.03% (p < 0.001) in 2020 compared to 2019. Mean injury severity score increased (2.2 to 2.4, p < 0.001) between 2019 and 2020. Injuries declined for struck by/against (- 4.9%) and overexertion (- 1.2%) mechanisms. Injuries proportionally increased for pedal cycles (2.8%), cut/pierce (1.5%), motor vehicle occupant (0.9%), other transportation (0.6%), fire/burn (0.5%) and firearms (0.3%) compared to all injuries in 2020 versus 2019. CONCLUSIONS: The proportion of PED injury-related visits in March through December 2020 increased compared to the same months in 2019. Racial and payor differences were noted. Mechanisms of injury seen in the PED during 2020 changed compared to 2019, and this can inform injury prevention initiatives.

The Covid-19 pandemic resulted in unprecedented restrictions on many public, private, and workplace activities throughout the United States and elsewhere. When restrictions were imposed, we were conducting a type III hybrid effectiveness-implementation trial in 10 pediatric trauma centers. In response to several pandemic-based restrictions, we had to develop procedures for engaging with potential research participants while limiting nonclinical, in-person interactions. This manuscript describes the procedures and challenges of obtaining electronic informed consent and assent in a multisite trauma center-based research study. We developed, tested, and trained staff to implement three options for obtaining informed consent. Twenty-five participants were enrolled in the effectiveness-implementation multisite trial during the first six months of utilization of the consent options, with eleven of these individuals enrolled using hybrid or electronic consent procedures. The challenges we identified involving electronic consent procedures included confusion over who would complete the electronic consent process and difficulties reconnecting with families. Lessons learned can strengthen electronic consent and assent procedures for future studies. More research is needed to further strengthen this process and increase its utilization.

White individuals in the United States (US) have historically had disproportionate access to firearms. The real-life availability of firearms, including those most lethal, may still be greater among White populations, manifesting in the number of victims in shootings. We compared the severity of US mass public shootings since Columbine by race and/or ethnicity of the perpetrator using The Violence Project Database of Mass Shooters, assessing fatalities (minimum four), total victims, type, and legal status of guns used. We used data visualization and Quasi-Poisson regression of victims minus four - accounting for truncation at 4 fatalities - to assess fatality and total victim rates comparing Non-Hispanic (NH) White with NH Black shooters, using winsorization to account for outlier bias from the 2017 Las Vegas shooting. In 104 total mass public shootings until summer 2021, NH White shooters had higher median fatalities (6 [IQR 5-9] versus 5 [IQR 4-6]) and total victims (9 [IQR 6-19] versus 7 [IQR 5-12]) per incident. Confidence intervals of NH Black versus NH White fatalities rate ratios (RR) ranged from 0.17-1.15, and of total victim RRs from 0.15-1.04. White shooters were overrepresented in mass public shootings with the most victims, typically involving legally owned assault rifles. To better understand the consequences when firearms are readily available, including assault rifles, we need a database of all US gun violence. Our assessment of total victims beyond fatalities emphasizes the large number of US gun violence survivors and the need to understand their experiences to capture the full impact of gun violence.

Objectives: The primary objective of this study was to examine opioid prescription frequency and identify differences across a national cohort of pediatric trauma centers in rates of prescribing opioids to injured adolescents at discharge. Methods: This was a retrospective observational study using electronic health records of injured adolescents (12-17 years) admitted to one of 10 pediatric trauma centers. Results: Of the 1345 electronic health records abstracted, 720 (53.5%, 95% CI 50.8 to 56.2) patients received opioid prescriptions at discharge with variability across sites (28.6%-72%). There was no association between patient factors and frequency of prescribing opioids. Center's trauma volume was significantly positively correlated with a higher rate of opioid prescribing at discharge (r=0.92, p=0.001). There was no significant difference between the frequency of opioid prescriptions at discharge among alcohol and other drugs (AOD)-positive patients (53.8%) compared with AOD-negative patients (53.5%). Conclusions: Across a sample of 10 pediatric trauma centers, just over half of adolescent trauma patients received an opioid prescription at discharge. Prescribing rates were similar for adolescent patients screening positive for AOD use and those screening negative. The only factor associated with a higher frequency of prescribing was trauma center volume. Consensus and dissemination of outpatient pain management best practices for adolescent trauma patients is warranted. Level of evidence: III-prognostic. Trial registration number: NCT03297060.

Pediatric critical care has continued to advance since our last article, "Pediatric Critical Care in Resource-Limited Settings-Overview and Lessons Learned" was written just 3 years ago. In that article, we reviewed the history, current state, and gaps in level of care between low- and middle-income countries (LMICs) and high-income countries (HICs). In this article, we have highlighted recent advancements in pediatric critical care in LMICs in the areas of research, training and education, and technology. We acknowledge how the COVID-19 pandemic has contributed to increasing the speed of some developments. We discuss the advancements, some lessons learned, as well as the ongoing gaps that need to be addressed in the coming decade. Continued understanding of the importance of equitable sustainable partnerships in the bidirectional exchange of knowledge and collaboration in all advancement efforts (research, technology, etc.) remains essential to guide all of us to new frontiers in pediatric critical care.

BACKGROUND: The American College of Surgeons Committee on Trauma recommends universal alcohol screening be part of the evaluation of admitted trauma patients. Yet, suboptimal screening rates have been reported for admitted adult and adolescent trauma patients. This lack of screening, in turn, has limited the ability of trauma services to provide patients with brief interventions during their hospital admission and subsequent referrals to treatment after discharge. The primary aim of this study was to examine current rates of alcohol and other drug screening with admitted injured adolescents across a national cohort of 10 pediatric trauma centers. METHODS: This retrospective observational study was nested within a larger adolescent screening, brief intervention, and referral to treatment implementation study (Clinicaltrials.gov NCT03297060). Ten pediatric trauma centers participated in a retrospective chart review of a random sample of adolescent trauma patients presenting for care between March 1, 2018, and November 30, 2018. RESULTS: Three hundred charts were abstracted across the 10 participating trauma centers (n = 30 per site). Screening rates varied substantially across centers from five (16.7%) to 28 (93.3%) of the 30 extracted charts. The most frequent screening type documented was blood alcohol concentration (BAC) (N = 80, 35.2% of all screens), followed by the CRAFFT (N = 79, 26.3%), and then the urine drug screen (UDS) (N = 77, 25.6%). The BAC test identified 11 patients as positive for recent alcohol use. The CRAFFT identified 11 positive patients. CONCLUSIONS: Alcohol and drug screening is underutilized for adolescents admitted to pediatric trauma centers. More research is warranted on how best to utilize the teachable moment of the pediatric trauma visit to ensure comprehensive screening of adolescent alcohol or other drug (AOD) use.

OBJECTIVE: To explore the effect of 23.4% hypertonic saline for management of elevated intracranial pressure in children admitted to our institution for severe traumatic brain injury. DESIGN: Single-center, retrospective medical chart analysis. SETTING: A PICU at a level 1 pediatric trauma center in the United States. PATIENTS: Children admitted for severe traumatic brain injury from 2006 to 2016 who received 23.4% hypertonic saline and whose intracranial pressures were measured within 5 hours of receiving 23.4% hypertonic saline. INTERVENTIONS: None. MEASUREMENTS AND MAIN RESULTS: Over the 10-year period, 1,587 children were admitted for traumatic brain injury, 155 of whom were deemed severe per this study's criteria. Forty of these children received at least one dose of hypertonic saline, but 14 were excluded for insufficient intracranial pressure data. Among the remaining 26 children, one hundred one 23.4% hypertonic saline boluses were used in the analysis. Use of 23.4% hypertonic saline was associated with a decrease in intracranial pressure of approximately 7 mm Hg at both within 1 hour after the bolus (p < 0.01) and 4 hours after the bolus (p < 0.01) when compared with the intracranial pressure measured within 1 hour before the hypertonic saline bolus. These effects remained significant after adjusting for Functional Status Scale score and CT Marshall scores. There was no statistically significant association between adjunctive therapies, such as antiepileptics and analgesics, and changes in intracranial pressure. There was no laboratory evidence of hyperkalemia or renal injury after use of 23.4% hypertonic saline. Across all hospitalizations, 65% of the study population demonstrated an abnormally elevated creatinine at least once, but only three episodes of acute kidney injury occurred in total, all before hypertonic saline administration. Eight of the 26 children in this analysis died during their hospitalization. The Functional Status Scale scores ranged from 6 to 26 with a mean of 12.2 and SD of 5.7. CONCLUSIONS: Use of 23.4% hypertonic saline with children admitted for severe traumatic brain injury is associated with a statistically significant decrease in intracranial pressure within 1 hour of use.

INTRODUCTION: Traumatic brain injury (TBI) is a major public health problem, particularly in children. Prognostication of injury severity at the time of presentation is difficult. The Abbreviated Injury Scale (AIS) is a commonly used anatomical-based coding system created to classify and describe injury severity after initial presentation, once test results are able to better define the anatomical characteristics of the injury. We hypothesize that the Head AIS can predict discharge destination in children after TBI. METHODS: The trauma registry database for a Pediatric Level 1 Trauma center was queried for patients age ≤14 years from 2006 to 2015 with a Head AIS>2. All diagnoses with head AIS>2 were retrieved. Since one patient can have multiple diagnoses with an AIS>2, we selected the diagnosis with highest Head AIS associated with each patient. The demographics, length of stay, and the discharge disposition of patients were retrieved. Descriptive statistics were performed and association of Head AIS with the length of stay and discharge disposition was determined using logistic regression. RESULTS: 393 pediatric patients (age≤14 years) with an Head AIS ≥3, (64.0% males, mean age = 6.2 S.D. 4.58) presented over 10 years. Head AIS was strongly associated with mortality; with 0.8%, 1.1% and 42.0% of patients with Head AIS of 3, 4 and 5, respectively, dying - odds ratio for Head AIS 5 over Head AIS 3 = 89 (logistic regression, p-value<0.001). 80.0% of deaths (23 patients) in this cohort occurred within 24-h of presentation. Head AIS was associated with an increase likelihood of discharge to rehabilitation with 1.2%, 7.7% and 47.0% of survivors discharging to rehabilitation for Head AIS of 3, 4 and 5. CONCLUSION: Head AIS can reliably predict discharge disposition to home, rehab or death. Calculation of Head AIS prior to discharge could lead to accurate prediction of discharge destination.

Trauma constitutes a significant cause of death and disability globally. The vast majority -about 95%, of the 5.8 million deaths each year, occur in low-and-middle-income countries (LMICs) 3-6. This includes almost 1 million children. The resource-adapted introduction of trauma care protocols, regionalized care and the growth specialized centers for trauma care within each LMIC are key to improved outcomes and the lowering of trauma-related morbidity and mortality globally. Resource limitations in LMICs make it necessary to develop injury prevention strategies and optimize the use of locally available resources when injury prevention measures fail. This will lead to the achievement of the best possible outcomes for critically ill and injured children. A commitment by the governments in LMICs working alone or in collaboration with international non-governmental organizations (NGOs) to provide adequate healthcare to their citizens is also crucial to improved survival after major trauma. The increase in global conflicts also has significantly deleterious effects on children, and governments and international organizations like the United Nations have a significant role to play in reducing these. This review details the evaluation and management of traumatic injuries in pediatric patients and gives some recommendations for improvements to trauma care in LMICs.

Pediatric critical care is an important component of reducing morbidity and mortality globally. Currently, pediatric critical care in low middle-income countries (LMICs) remains in its infancy in most hospitals. The majority of hospitals lack designated intensive care units, healthcare staff trained to care for critically ill children, adequate numbers of staff, and rapid access to necessary medications, supplies and equipment. In addition, most LMICs lack pediatric critical care training programs for healthcare providers or certification procedures to accredit healthcare providers working in their pediatric intensive care units (PICU) and high dependency areas. PICU can improve the quality of pediatric care in general and, if properly organized, can effectively treat the severe complications of high burden diseases, such as diarrhea, severe malaria, and respiratory distress using low-cost interventions. Setting up a PICU in a LMIC setting requires planning, specific resources, and most importantly investment in the nursing and permanent medical staff. A thoughtful approach to developing pediatric critical care services in LMICs starts with fundamental building blocks: training healthcare professionals in skills and knowledge, selecting resource appropriate effective equipment, and having supportive leadership to provide an enabling environment for appropriate care. If these fundamentals can be built on in a sustainable manner, an appropriate critical care service will be established with the potential to significantly decrease pediatric morbidity and mortality in the context of public health goals as we reach toward the sustainable development goals.

The authors describe a multiinstitutional collaborative project to address a gap in global health training by creating a free online platform to share a curriculum for performing procedures in resource-limited settings. This curriculum called PEARLS (Procedural Education for Adaptation to Resource-Limited Settings) consists of peer-reviewed instructional and demonstration videos describing modifications for performing common pediatric procedures in resource-limited settings. Adaptations range from the creation of a low-cost spacer for inhaled medications to a suction chamber for continued evacuation of a chest tube. By describing the collaborative process, we provide a model for educators in other fields to collate and disseminate procedural modifications adapted for their own specialty and location, ideally expanding this crowd-sourced curriculum to reach a wide audience of trainees and providers in global health.

Traumatic injuries are a significant cause of death and disability worldwide. The vast majority of these injuries occur in low- and middle-income countries (LMICs). Attention to protocolized care and adaptations to treatments based on availability of resources, regionalization of care, and the development of centers of excellence within each LMIC are crucial to improving outcomes and lowering trauma-related morbidity and mortality worldwide. Given limitations in the availability of the resources necessary to provide the levels of care found in high-income countries, strategies to prevent trauma and make the best use of available resources when prevention fails, and thus achieve the best possible outcomes for injured and critically ill children, are vital. Overall, a commitment on the part of governments in LMICs to the provision of adequate health care services to their populations will improve the outcomes of injured children. This review details the evaluation and management of traumatic injuries in pediatric patients and gives some recommendations for improvements to trauma care in LMICs.

Providing evidence-based care to the critically ill child including assessment, evaluation, and management in resource-limited settings provides unique challenges and limitless opportunities to significantly impact morbidity and mortality in these settings. Difficulties encountered include: determining which disease processes will benefit most from critical care in resource-limited settings, lack of triage tools and adjuncts to help with assessment, finite laboratory and radiological tests, limited understanding of key findings in critically ill/injured pediatric patients, (especially by those without pediatric focused training), and finally, lack of supplies, medicines, equipment, and training of health care providers to appropriately treat critically ill children in these resource-limited settings. In this review, the most common problems encountered and possible solutions to overcome these obstacles are discussed.

Sixty elementary schools in Minneapolis were asked to participate in a study to evaluate the most effective education method to increase booster seat knowledge and use in kindergarten-age children. School personnel selected one of the following interventions: (1) written information, (2) parent education class and a free booster seat, or (3) student education and a free booster seat. Twenty schools participated, with 132 parents completing the telephone interview 3 to 6 months post-survey. Providing instructions to parent groups and teaching children in the classroom, along with providing an incentive booster seat, was shown to increase booster seat use. Providing information only was found to be ineffective. Pediatric and school nurses should focus their injury prevention efforts beyond written materials. Results indicate that presentations for children and their parents, along with incentives, can result in changes in behavior.

BACKGROUND: Most injuries to infants occur at home and are known to have a modifiable component. Additional information on safety behaviors, practices, and device ownership could inform prevention programs aimed at reducing injury-related race and ethnic disparities. METHODS: This study is a secondary data analysis of race and ethnic differences in home safety using data collected by the Connecticut, Ohio, Pennsylvania, Minnesota, and New York sites of the Injury Free Coalition for Kids. Study participants were English- and Spanish-speaking parents/guardians of infants aged 4 months to 6 months. All participants received a voucher redeemable for free safety devices and educational materials. RESULTS: Five hundred forty-two study participants were 37.8% black, 41.7% Hispanic, 10.5% white, and 10.0% other race. Whites more frequently owned/had safety devices including cabinet latches (chi2 =28.9, p < 0.0001), drawer latches (chi2 =21.4, p < 0.0001), bath thermometers (chi2 =22.5, p < 0.0001), electric outlet covers (chi2 =15.9, p = 0.0004), and poison control number (chi 2=93.8, p < 0.0001). Practice of unsafe behaviors, such as stomach sleep position, was higher in blacks (29.3%) than whites (15.8%) or Hispanics (17.7%) (chi2 =11.8, p < 0.0083). Overall, 62.1% redeemed vouchers, but this varied significantly by ethnicity: blacks (42.2%), non-Hispanic whites (64.6%), and Hispanics (76.3%) (chi2 = 48.5, p < 0.0001). CONCLUSIONS: Compared with whites, both blacks and Hispanics were less likely to own a variety of safety devices at baseline, but Hispanics were more likely than blacks to redeem vouchers. This one shot voucher program was effective at increasing device ownership, but was not sufficient alone to achieve population saturation of safety devices.

OBJECTIVE: To determine the frequency of positive blood cultures in patients with fevers in the initial 48-hour postoperative period. STUDY DESIGN: All patients who had blood cultures drawn during the initial 48 hours postoperatively while in the pediatric intensive care unit (PICU) at the University of Minnesota Children's Hospital-Fairview during an 18-month period were included in the current study. Six hundred two postoperative patients were admitted to the PICU during the study period. Patients with a temperature >100.4 degrees F and who had blood cultures drawn were identified. Patients for whom the operative procedure was not the first in that admission, those discharged in <48 hours, and those with an indwelling central venous catheter for >24 hours before their admission were excluded. RESULTS: Sixty-six of these patients were febrile and had blood cultures drawn in the initial 48 hours postoperatively. One hundred eleven blood cultures were obtained. A single (0.9%) blood culture was positive. The cost per positive culture was estimated at $23,532. CONCLUSIONS: Even in patients admitted to the PICU, fever in the initial 48-hour postoperative period is unlikely to represent bacteremia in low-risk pediatric patients. Blood cultures in these patients are, therefore, unlikely to yield positive results. Procurement of blood cultures in this patient population is not justified. Cessation of the practice of blood culture procurement in this patient population may both focus care and provide enable meaningful cost savings.

BACKGROUND: Abusive head trauma (AHT) in young children usually has a severe outcome when associated with hypoxic-ischemic encephalopathy (HIE), which is best characterized by MRI in the acute or subacute phase utilizing diffusion-weighted imaging (DWI). HIE in this setting has been hypothesized to result from stretching of the spinal cord, brainstem, or vasculature. OBJECTIVE: To provide clinical correlation in patients with unilateral HIE and to postulate a mechanism in the setting of suspected AHT. MATERIALS AND METHODS: IRB approval was obtained. Over a 5-year period, the medical records and images were reviewed of the 53 children < or = 3 years of age who presented with acute head trauma according to the hospital registry. The children were subselected in order to determine how many suffered either HIE or AHT, and to detect those with unilateral HIE. RESULTS: In 11 of the 53 children, the etiology of the head trauma was highly suspicious for abuse. In 38 the head trauma was accidental and in 4 the trauma was of unknown etiology and at the time of this report was unresolved legally. Of the 53, 4 suffered HIE confirmed by CT or MRI. In three of these four with HIE the trauma was considered highly suspicious for AHT. Two of these three were the only patients with unilateral HIE, and both (7 months and 14 months of age) presented with early subacute phase HIE seen on DW MRI (range 4-7 days) and are described in detail with clinical correlation. The third child with AHT and HIE had bilateral findings. In the fourth patient the HIE was bilateral and was considered accidental. The work-up for both patients with unilateral HIE included head CT, craniocervical MRI, and craniocervical MR angiography (MRA). In both, there was mostly unilateral, deep white matter restricted diffusion, with subdural hematomas that were small compared to the extent of hypoxic-ischemic insult, and no skull fracture. Craniocervical MRA and axial thin-section fat-saturation images were negative for dissection, brainstem, or cord injury. Legal authorities obtained a confession of inflicted injury in one and a partial confession in the second (which did not fit the extent of injury). Five other children with HIE (based on DWI) were found during this period who had not suffered head trauma; all were bilateral insults. CONCLUSION: HIE associated with AHT might present with largely unilateral white matter injury on DWI following extensive cortical infarction. We propose that unilateral HIE in a young child might be a sign of AHT and might result from cervical vascular compression, whether from kinking during hyperflexion/hyperextension or from direct strangulation.

This study examined the sensitivity of diffusion tensor imaging (DTI) to microstructural white matter (WM) damage in mild and moderate pediatric traumatic brain injury (TBI). Fourteen children with TBI and 14 controls ages 10-18 had DTI scans and neurocognitive evaluations at 6-12 months post-injury. Groups did not differ in intelligence, but children with TBI showed slower processing speed, working memory and executive deficits, and greater behavioral dysregulation. The TBI group had lower fractional anisotropy (FA) in three WM regions: inferior frontal, superior frontal, and supracallosal. There were no group differences in corpus callosum. FA in the frontal and supracallosal regions was correlated with executive functioning. Supracallosal FA was also correlated with motor speed. Behavior ratings showed correlations with supracallosal FA. Parent-reported executive deficits were inversely correlated with FA. Results suggest that DTI measures are sensitive to long-term WM changes and associated with cognitive functioning following pediatric TBI.
