Although concussion-related emergency department (ED) visits increased after the passage of concussion laws, little is known about how the laws may disproportionately impact ED utilization and ...associated health care costs among children in different demographic groups.
Our aim was to examine the patient and clinical characteristics of pediatric ED visits and associated health care costs for sports- and recreation-related concussions (SRRCs) before and after concussion law enactment.
We retrospectively analyzed ED visits for SRRCs by children ages 5–18 years between 2006 and 2014 in the Pediatric Health Information System database (n = 123,220). ED visits were categorized as “pre-law,” “immediate post-law,” and “post-law” according to the respective state concussion law's effective date. Multinomial logistic regression models were used to assess the impact of the law on ED utilization.
The majority of visits were by males (n = 83,208; 67.6%), children aged 10–14 years (n = 49,863; 40.9%), and privately insured patients (n = 62,376; 50.6%). Female sex, older age, and insured by Medicaid/Medicare were characteristics associated with increased ED visits during the immediate post-law and post-law periods compared to their counterparts. A significant decrease in proportion of imaging use was observed from pre-law to post-law (adjusted odds ratio 0.49; 95% confidence interval 0.47–0.50; p < 0.0001). While annual adjusted costs per ED visits decreased, annual total adjusted costs per hospital for SRRCs increased from pre-law to post-law (p < 0.0001).
Concussion laws might have impacted pediatric concussion-related ED utilization, with increased annual total adjusted costs. These results may have important implications for policy interventions and their effects on health care systems.
Traumatic injury is the leading cause of death in children and adolescents. Hemorrhagic shock remains a common and preventable cause of death in the pediatric trauma patients. A paucity of ...high-quality evidence is available to guide specific aspects of hemorrhage control in this population. We sought to identify high-priority research topics for the care of pediatric trauma patients in hemorrhagic shock.
A panel of 16 consensus multidisciplinary committee members from the Pediatric Traumatic Hemorrhagic Shock Consensus Conference developed research priorities for addressing knowledge gaps in the care of injured children and adolescents in hemorrhagic shock. These ideas were informed by a systematic review of topics in this area and a discussion of these areas in the consensus conference. Research priorities were synthesized along themes and prioritized by anonymous voting.
Eleven research priorities that warrant additional investigation were identified by the consensus committee. Areas of proposed study included well-designed clinical trials and evaluations, including increasing the speed and accuracy of identifying and treating hemorrhagic shock, defining the role of whole blood and tranexamic acid use, and assessment of the utility and appropriate use of viscoelastic techniques during early resuscitation. The committee recommended the need to standardize essential definitions, data elements, and data collection to facilitate research in this area.
Research gaps remain in many areas related to the care of hemorrhagic shock after pediatric injury. Addressing these gaps is needed to develop improved evidence-based recommendations for the care of pediatric trauma patients in hemorrhagic shock.
A robust estimation method is needed to prevent medication dosing and equipment sizing errors and improve time to administration during paediatric resuscitation. An electronic measurement with ...computer interface may improve accuracy and alleviate cognitive burden. This study evaluates the accuracy of two electronic height measurement methods, a laser and an optical device, and compares them to the Broselow™ Pediatric Emergency Tape (BT) for weight estimation.
We enrolled children ages 0–14 years from the emergency department of a free-standing, academic children’s hospital. We obtained sex, body habitus, true weight, true height, BT colour, and experimental heights. We converted experimental height measurements into weight estimates using standardised growth charts. We calculated Pearson correlations between experimental and actual measurements and the percentages of weight estimates within 10% and 20% of true weights. We repeated analyses on a restricted cohort of children 0–11 years, the intended BT age range.
We enrolled 198 children. The laser, optical device and BT weight estimates had strong positive correlations with the actual weight measurements with Pearson’s correlation coefficients of 0.946, p < 0.0001, 0.965, p < 0.0001, and 0.825, p < 0.0001 respectively. 47.8% of optical weight estimates fell within 10% of actual weight and 80.6% within 20%, compared to 40.5% and 75.4% of laser estimates and 39.8% and 65.1% of BT estimates.
Electronic-based weight estimates were more accurate than the BT. The accuracy of medication dosing and equipment sizing during paediatric resuscitation may be improved by integrating optical height-based weight estimates with electronic clinical decision support.
In 2017, the Health Resources and Services Administration's Maternal Child and Health Bureau's Emergency Medical Services for Children program implemented a performance measure for State Partnership ...grants to increase the percentage of EMS agencies within each state that have designated individuals who coordinate pediatric emergency care, also called a pediatric emergency care coordinator (PECC). The PECC Learning Collaborative (PECCLC) was established to identify best practices to achieve this goal. This study's objective is to report on the structure and outcomes of the PECCLC conducted among nine states.
This study used quantitative and qualitative methods to evaluate outcomes from the PECCLC. Participating state representatives engaged in a 6-month collaborative that included monthly learning sessions with subject matter experts and support staff and concluded with a two-day in-person meeting. Outcomes included reporting the number of PECCs recruited, identifying barriers and enablers to PECC recruitment, characterizing best practices to support PECCs, and identifying barriers and enablers to enhance and sustain the PECC role. Outcomes were captured by self-report from participating state representatives and longitudinal qualitative interviews conducted with representative PECCs at 6 and 18 months after conclusion of the PECCLC.
During the 6-month collaborative, states recruited 341 PECCs (92% of goal). Follow up at 5 months post-collaborative revealed an additional recruitment of 184 for a total of 525 PECCs (142% of the goal). Feedback from state representatives and PECCs revealed the following barriers: competition from other EMS responsibilities, budgetary constraints, lack of incentive for agencies to create the position, and lack of requirement for establishing the role. Enablers identified included having an EMS agency recognition program that includes the PECC role, train-the-trainer programs, and inclusion of the PECC role in agency licensure requirements. Longitudinal interviews with PECCs identified that the most common activity associated with their role was pediatric-specific education and the most important need for PECC success was agency-level support.
Over the 6-month Learning Collaborative, nine states were successful in recruiting a substantial number of PECCs. Financial and time constraints were significant barriers to statewide PECC recruitment, yet these can be potentially addressed by EMS agency recognition programs.
The Galileo mission to Jupiter revealed that Europa is an ocean world. The Galileo magnetometer experiment in particular provided strong evidence for a salty subsurface ocean beneath the ice shell, ...likely in contact with the rocky core. Within the ice shell and ocean, a number of tectonic and geodynamic processes may operate today or have operated at some point in the past, including solid ice convection, diapirism, subsumption, and interstitial lake formation.
The science objectives of the Europa Clipper mission include the characterization of Europa’s interior; confirmation of the presence of a subsurface ocean; identification of constraints on the depth to this ocean, and on its salinity and thickness; and determination of processes of material exchange between the surface, ice shell, and ocean.
Three broad categories of investigation are planned to interrogate different aspects of the subsurface structure and properties of the ice shell and ocean: magnetic induction, subsurface radar sounding, and tidal deformation. These investigations are supplemented by several auxiliary measurements. Alone, each of these investigations will reveal unique information. Together, the synergy between these investigations will expose the secrets of the Europan interior in unprecedented detail, an essential step in evaluating the habitability of this ocean world.
CSF shunt placement is the primary therapy for hydrocephalus; however, shunt malfunctions remain common and lead to neurological deficits if missed. There is a lack of literature characterizing the ...epidemiology of children with possible shunt malfunctions presenting to United States emergency departments (EDs).
A retrospective study was conducted of the 2006-2017 National Emergency Department Sample. The data were queried using an exhaustive list of Current Procedural Terminology and International Classification of Diseases, Ninth Revision and International Classification of Diseases, Tenth Revision codes representing children with hydrocephalus diagnoses, diagnostic imaging for shunt malfunctions, and shunt-related surgical revision procedures.
In 2017, there were an estimated 16,376 ED visits for suspected shunt malfunction. Children were more commonly male (57.9%), ages 0-4 years (42.2%), and publicly insured (55.8%). Many did not undergo diagnostic imaging (37.2%), and of those who did, most underwent head CT scans (43.7%). Between 2006 and 2017, pediatric ED visits for suspected shunt malfunction increased 18% (95% CI 12.1-23.8). The use of MRI increased substantially (178.0%, 95% CI 176.9-179.2). Visits resulting in discharge home from the ED increased by 76.3% (95% CI 73.1-79.4), and those involving no surgical intervention increased by 32.9% (95% CI 29.2-36.6).
Between 2006 and 2017, ED visits for children to rule out shunt malfunction increased, yet there was a decline in surgical intervention and an increase in discharges home from the ED. Possible contributing factors include improved clinical criteria for shunt evaluation, alternative CSF diversion techniques, changing indications for shunt placement, and increased use of advanced imaging in the ED.

This study aimed to compare children diagnosed with cervical spinal cord injury without radiographic abnormality (SCIWORA) relative to whether there is evidence of cervical spinal cord abnormalities ...on magnetic resonance imaging (MRI).
We conducted a planned subanalysis of a cohort of children younger than 16 years with blunt cervical spine injury presenting to Pediatric Emergency Care Applied Research Network centers from January 2000 to December 2004 who underwent cervical MRI and did not have bony or ligamentous injury identified on neuroimaging. We defined SCIWORA with normal MRI finding as children with clinical evidence of cervical cord injury and a normal MRI finding and compared them with children with SCIWORA who had cervical cord signal changes on MRI (abnormal MRI finding).
Of the children diagnosed with cervical spine injury, 55% (297 of 540) were imaged with MRI; 69 had no bony or ligamentous injuries and were diagnosed with SCIWORA by clinical evaluation; 54 (78%) had normal MRI finding, and 15 (22%) had cervical cord signal changes on MRI (abnormal MRI finding). Children with abnormal MRI findings were more likely to receive operative stabilization (0% normal MRI finding vs. 20% abnormal MRI finding) and have persistent neurologic deficits at initial hospital discharge (6% normal MRI finding vs. 67% abnormal MRI finding).
Children diagnosed with SCIWORA but with normal MRI finding in our cohort presented differently and had substantially more favorable clinical outcomes than those with cervical cord abnormalities on MRI.
Epidemiologic study, level III.
Background
The risk for cervical spine injury (CSI) must be assessed in children who sustain blunt trauma. The Pediatric Emergency Care Applied Research Network (PECARN) retrospectively derived CSI ...model identifies CSI risk in children based on emergency department (ED) provider observations. The objective of this pilot study was to determine the univariate association of emergency medical services (EMS) provider‐observed historical, mechanistic, and physical examination factors with CSI in injured children. Secondarily, we assessed the performance of the previously identified eight PECARN CSI risk factors (PECARN model) based exclusively on EMS provider observation.
Methods
We conducted a four‐center, prospective observational study of children 0 to 17 years old who were transported by EMS after blunt trauma and underwent spinal motion restriction or trauma team activation in the ED. In the ED, EMS providers recorded their observations for a priori determined CSI risk factors. CSIs were classified by reviewing imaging, consultations, and/or telephone follow‐up. We calculated bivariable relative risks and test characteristics for the PECARN model based solely on EMS provider observations.
Results
Of 1,372 enrolled children, 25 (1.8%) had CSIs. Of the a priori determined CSI risk factors, seven factors had bivariable associations with CSIs: axial load, altered mental status, signs of basilar skull fracture, substantial torso injury, substantial thoracic injury, respiratory distress, and decreased oxygen saturation. The PECARN model (high‐risk motor vehicle collision, diving mechanism, predisposing condition, neck pain, decreased neck mobility, altered mental status, neurologic deficits, and/or substantial torso injury) exhibited the following test characteristics when based on EMS provider observations: sensitivity = 96.0% (95% confidence interval CI = 88.3% to 100.0%); negative predictive value = 99.8% (95% CI = 99.4% to 100.0%); specificity = 38.5% (95% CI = 35.9% to 41.1%); and positive predictive value = 2.8% (95% CI = 1.7% to 3.9%).
Conclusion
EMS providers can identify risk factors associated with CSI in injured children who experience blunt trauma. These risk factors may be considered for inclusion in a pediatric CSI decision rule specific to the prehospital setting.

Once a child is determined to be at risk of having a cervical spine injury, clinicians must take appropriate precautions to avoid potential worsening of neurologic deficits. Occasionally these ...decisions are made in the absence of adequate cervical spine imaging when dealing with a child's unstable airway or other life-threatening injuries. Furthermore, clinicians have to make decisions regarding appropriate diagnostic testing to evaluate for potential injury. Decisions regarding testing should take into consideration the clinical presentation of the patient, aiming to order appropriate testing for those at risk and avoid unnecessary testing for those without signs of cervical spine injury.
Abstract
“Complete streets” policies require transportation engineers to make provisions for pedestrians, bicyclists, and mass transit users. These policies may make bicycling safer for individual ...cyclists while increasing the overall number of bicycle fatalities if more people cycle due to improved infrastructure. We merged county-level records of complete streets policies with Fatality Analysis Reporting System counts of cyclist fatalities occurring between January 2000 and December 2015. Because comprehensive county-level estimates of numbers of cyclists were not available, we used bicycle commuter estimates from the American Community Survey and the US Census as a proxy for the cycling population and limited analysis to 183 counties (accounting for over half of the US population) for which cycle commuting estimates were consistently nonzero. We used G-computation to estimate the effect of complete streets policies on overall numbers of cyclist fatalities while also accounting for potential policy effects on the size of the cycling population. Over a period of 16 years, 5,254 cyclists died in these counties, representing 34 fatalities per 100,000 cyclist-years. We estimated that complete streets policies made cycling safer, averting 0.6 fatalities per 100,000 cyclist-years (95% confidence interval: −1.0, −0.3) by encouraging a 2.4% increase in cycling but producing only a 0.7% increase in cyclist fatalities. G-computation is a useful tool for understanding the impact of policy on risk and exposure.
