Optimizing Advanced Imaging of the Pediatric Patient in the Emergency Department: Policy Statement.

Advanced imaging, including ultrasonography, computed tomography, and magnetic resonance imaging (MRI), is an integral component to the evaluation and management of ill and injured children in the emergency department. As with any test or intervention, the benefits and potential impacts on management must be weighed against the risks to ensure that high-value care is being delivered. There are important considerations specific to the pediatric patient related to the ordering and interpretation of advanced imaging. This policy statement provides guidelines for institutions and those who care for children to optimize the use of advanced imaging in the emergency department setting and was coauthored by experts in pediatric and general emergency medicine, pediatric radiology, and pediatric surgery. The intent is to guide decision-making where children may access care.

Changes in Emergency Department Pediatric Readiness and Mortality.

Importance: High emergency department (ED) pediatric readiness is associated with improved survival, but the impact of changes to ED readiness is unknown. Objective: To evaluate the association of changes in ED pediatric readiness at US trauma centers between 2013 and 2021 with pediatric mortality. Design, Setting, and Participants: This retrospective cohort study was performed from January 1, 2012, through December 31, 2021, at EDs of trauma centers in 48 states and the District of Columbia. Participants included injured children younger than 18 years with admission or injury-related death at a participating trauma center, including transfers to other trauma centers. Data analysis was performed from May 2023 to January 2024. Exposure: Change in ED pediatric readiness, measured using the weighted Pediatric Readiness Score (wPRS, range 0-100, with higher scores denoting greater readiness) from national assessments in 2013 and 2021. Change groups included high-high (wPRS ≥93 on both assessments), low-high (wPRS <93 in 2013 and wPRS ≥93 in 2021), high-low (wPRS ≥93 in 2013 and wPRS <93 in 2021), and low-low (wPRS <93 on both assessments). Main Outcomes and Measures: The primary outcome was lives saved vs lost, according to ED and in-hospital mortality. The risk-adjusted association between changes in ED readiness and mortality was evaluated using a hierarchical, mixed-effects logistic regression model based on a standardized risk-adjustment model for trauma, with a random slope-random intercept to account for clustering by the initial ED. Results: The primary sample included 467 932 children (300 024 boys [64.1%]; median [IQR] age, 10 [4 to 15] years; median [IQR] Injury Severity Score, 4 [4 to 15]) at 417 trauma centers. Observed mortality by ED readiness change group was 3838 deaths of 144 136 children (2.7%) in the low-low ED group, 1804 deaths of 103 767 children (1.7%) in the high-low ED group, 1288 deaths of 64 544 children (2.0%) in the low-high ED group, and 2614 deaths of 155 485 children (1.7%) in the high-high ED group. After risk adjustment, high-readiness EDs (persistent or change to) had 643 additional lives saved (95% CI, -328 to 1599 additional lives saved). Low-readiness EDs (persistent or change to) had 729 additional preventable deaths (95% CI, -373 to 1831 preventable deaths). Secondary analysis suggested that a threshold of wPRS 90 or higher may optimize the number of lives saved. Among 716 trauma centers that took both assessments, the median (IQR) wPRS decreased from 81 (63 to 94) in 2013 to 77 (64 to 93) in 2021 because of reductions in care coordination and quality improvement. Conclusions and Relevance: Although the findings of this study of injured children in US trauma centers were not statistically significant, they suggest that trauma centers should increase their level of ED pediatric readiness to reduce mortality and increase the number of pediatric lives saved after injury.

Diagnostic Performance of Magnetic Resonance Imaging for Pediatric Ovarian Neoplasms: A Multi-Institutional Review.

STUDY OBJECTIVE: To assess the diagnostic performance of MRI to predict ovarian malignancy alone and compared with other diagnostic studies. METHODS: A retrospective analysis was conducted of patients aged 2-21 years who underwent ovarian mass resection between 2009 and 2021 at 11 pediatric hospitals. Sociodemographic information, clinical and imaging findings, tumor markers, and operative and pathology details were collected. Diagnostic performance for detecting malignancy was assessed by calculating sensitivity, specificity, positive predictive value (PPV), and negative predictive value (NPV) for MRI with other diagnostic modalities. RESULTS: One thousand and fifty-three patients, with a median age of 14.6 years, underwent resection of an ovarian mass; 10% (110/1053) had malignant disease on pathology, and 13% (136/1053) underwent preoperative MRI. MRI sensitivity, specificity, PPV, and NPV were 60%, 94%, 60%, and 94%. Ultrasound sensitivity, specificity, PPV, and NPV were 31%, 99%, 73%, and 95%. Tumor marker sensitivity, specificity, PPV, and NPV were 90%, 46%, 22%, and 96%. MRI and ultrasound concordance was 88%, with sensitivity, specificity, PPV, and NPV of 33%, 99%, 75%, and 94%. MRI sensitivity in ultrasound-discordant cases was 100%. MRI and tumor marker concordance was 88% with sensitivity, specificity, PPV, and NPV of 100%, 86%, 64%, and 100%. MRI specificity in tumor marker-discordant cases was 100%. CONCLUSION: Diagnostic modalities used to assess ovarian neoplasms in pediatric patients typically agree. In cases of disagreement, MRI is more sensitive for malignancy than ultrasound and more specific than tumor markers. Selective use of MRI with preoperative ultrasound and tumor markers may be beneficial when the risk of malignancy is uncertain. CONCISE ABSTRACT: This retrospective review of 1053 patients aged 2-21 years who underwent ovarian mass resection between 2009 and 2021 at 11 pediatric hospitals found that ultrasound, tumor markers, and MRI tend to agree on benign vs malignant, but in cases of disagreement, MRI is more sensitive for malignancy than ultrasound.

Relationship between the COVID-19 pandemic and structural inequalities within the pediatric trauma population.

BACKGROUND: The COVID-19 pandemic disrupted social, political, and economic life across the world, shining a light on the vulnerability of many communities. The objective of this study was to assess injury patterns before and after implementation of stay-at-home orders (SHOs) between White children and children of color and across varying levels of vulnerability based upon children's home residence. METHODS: A multi-institutional retrospective study was conducted evaluating patients < 18 years with traumatic injuries. A "Control" cohort from an averaged March-September 2016-2019 time period was compared to patients injured after SHO initiation-September 2020 ("COVID" cohort). Interactions between race/ethnicity or social vulnerability index (SVI), a marker of neighborhood vulnerability and socioeconomic status, and the COVID-19 timeframe with regard to the outcomes of interest were assessed using likelihood ratio Chi-square tests. Differences in injury intent, type, and mechanism were then stratified and explored by race/ethnicity and SVI separately. RESULTS: A total of 47,385 patients met study inclusion. Significant interactions existed between race/ethnicity and the COVID-19 SHO period for intent (p < 0.001) and mechanism of injury (p < 0.001). There was also significant interaction between SVI and the COVID-19 SHO period for mechanism of injury (p = 0.01). Children of color experienced a significant increase in intentional (COVID 16.4% vs. Control 13.7%, p = 0.03) and firearm (COVID 9.0% vs. Control 5.2%, p < 0.001) injuries, but no change was seen among White children. Children from the most vulnerable neighborhoods suffered an increase in firearm injuries (COVID 11.1% vs. Control 6.1%, p = 0.001) with children from the least vulnerable neighborhoods having no change. All-terrain vehicle (ATV) and bicycle crashes increased for children of color (COVID 2.0% vs. Control 1.1%, p = 0.04 for ATV; COVID 6.7% vs. Control 4.8%, p = 0.02 for bicycle) and White children (COVID 9.6% vs. Control 6.2%, p < 0.001 for ATV; COVID 8.8% vs. Control 5.8%, p < 0.001 for bicycle). CONCLUSIONS: In contrast to White children and children from neighborhoods of lower vulnerability, children of color and children living in higher vulnerability neighborhoods experienced an increase in intentional and firearm-related injuries during the COVID-19 pandemic. Understanding inequities in trauma burden during times of stress is critical to directing resources and targeting intervention strategies.

Setting an agenda for a national pediatric trauma system: Operationalization of the Pediatric Trauma State Assessment Score.

ABSTRACT: Pediatric trauma system development is essential to public health infrastructure and pediatric health systems. Currently, trauma systems are managed at the state level, with significant variation in consideration of pediatric needs. A recently developed Pediatric Trauma System Assessment Score (PTSAS) demonstrated that states with lower PTSAS have increased pediatric mortality from trauma. Critical gaps are identified within 6 PTSAS domains: Legislation & Funding, Access to Care, Injury Prevention and Recognition, Disaster, Quality Improvement & Trauma Registry, and Pediatric Readiness. For each gap, a recommendation is provided regarding the necessary steps to address these challenges. Existing national organizations, including governmental, professional, and advocacy, highlight the potential partnerships that could be fostered to support efforts to address existing gaps. The organizations created under the U.S. Administration are described to highlight the ongoing efforts to support the development of pediatric emergency health systems.It is no longer sufficient to describe the disparities in pediatric trauma outcomes without taking action to ensure the health system is equipped to manage injured children. By capitalizing on organizations that intersect with trauma and emergency systems to address known gaps, we can reduce the impact of injury on all children across the United States.

Disaster planning for a surgical surge: when mass trauma threatens to overwhelm your operating rooms.

Mass casualty events particularly those requiring multiple simultaneous operating rooms are of increasing concern. Existing literature predominantly focuses on mass casualty care in the emergency department. Hospital disaster plans should include a component focused on preparing for multiple simultaneous operations. When developing this plan, representatives from all segments of the perioperative team should be included. The plan needs to address activation, communication, physical space, staffing, equipment, blood and medications, disposition offloading, special populations, and rehearsal.

Reducing Unnecessary Oophorectomies for Benign Ovarian Neoplasms in Pediatric Patients.

Importance: Although most ovarian masses in children and adolescents are benign, many are managed with oophorectomy, which may be unnecessary and can have lifelong negative effects on health. Objective: To evaluate the ability of a consensus-based preoperative risk stratification algorithm to discriminate between benign and malignant ovarian pathology and decrease unnecessary oophorectomies. Design, Setting, and Participants: Pre/post interventional study of a risk stratification algorithm in patients aged 6 to 21 years undergoing surgery for an ovarian mass in an inpatient setting in 11 children's hospitals in the United States between August 2018 and January 2021, with 1-year follow-up. Intervention: Implementation of a consensus-based, preoperative risk stratification algorithm with 6 months of preintervention assessment, 6 months of intervention adoption, and 18 months of intervention. The intervention adoption cohort was excluded from statistical comparisons. Main Outcomes and Measures: Unnecessary oophorectomies, defined as oophorectomy for a benign ovarian neoplasm based on final pathology or mass resolution. Results: A total of 519 patients with a median age of 15.1 (IQR, 13.0-16.8) years were included in 3 phases: 96 in the preintervention phase (median age, 15.4 [IQR, 13.4-17.2] years; 11.5% non-Hispanic Black; 68.8% non-Hispanic White); 105 in the adoption phase; and 318 in the intervention phase (median age, 15.0 [IQR, 12.9-16.6)] years; 13.8% non-Hispanic Black; 53.5% non-Hispanic White). Benign disease was present in 93 (96.9%) in the preintervention cohort and 298 (93.7%) in the intervention cohort. The percentage of unnecessary oophorectomies decreased from 16.1% (15/93) preintervention to 8.4% (25/298) during the intervention (absolute reduction, 7.7% [95% CI, 0.4%-15.9%]; P = .03). Algorithm test performance for identifying benign lesions in the intervention cohort resulted in a sensitivity of 91.6% (95% CI, 88.5%-94.8%), a specificity of 90.0% (95% CI, 76.9%-100%), a positive predictive value of 99.3% (95% CI, 98.3%-100%), and a negative predictive value of 41.9% (95% CI, 27.1%-56.6%). The proportion of misclassification in the intervention phase (malignant disease treated with ovary-sparing surgery) was 0.7%. Algorithm adherence during the intervention phase was 95.0%, with fidelity of 81.8%. Conclusions and Relevance: Unnecessary oophorectomies decreased with use of a preoperative risk stratification algorithm to identify lesions with a high likelihood of benign pathology that are appropriate for ovary-sparing surgery. Adoption of this algorithm might prevent unnecessary oophorectomy during adolescence and its lifelong consequences. Further studies are needed to determine barriers to algorithm adherence.

Pediatric Cervical Spine Injury Following Blunt Trauma in Children Younger Than 3 Years: The PEDSPINE II Study.

Importance: There is variability in practice and imaging usage to diagnose cervical spine injury (CSI) following blunt trauma in pediatric patients. Objective: To develop a prediction model to guide imaging usage and to identify trends in imaging and to evaluate the PEDSPINE model. Design, Setting, and Participants: This cohort study included pediatric patients (<3 years years) following blunt trauma between January 2007 and July 2017. Of 22 centers in PEDSPINE, 15 centers, comprising level 1 and 2 stand-alone pediatric hospitals, level 1 and 2 pediatric hospitals within an adult hospital, and level 1 adult hospitals, were included. Patients who died prior to obtaining cervical spine imaging were excluded. Descriptive analysis was performed to describe the population, use of imaging, and injury patterns. PEDSPINE model validation was performed. A new algorithm was derived using clinical criteria and formulation of a multiclass classification problem. Analysis took place from January to October 2022. Exposure: Blunt trauma. Main Outcomes and Measures: Primary outcome was CSI. The primary and secondary objectives were predetermined. Results: The current study, PEDSPINE II, included 9389 patients, of which 128 (1.36%) had CSI, twice the rate in PEDSPINE (0.66%). The mean (SD) age was 1.3 (0.9) years; and 70 patients (54.7%) were male. Overall, 7113 children (80%) underwent cervical spine imaging, compared with 7882 (63%) in PEDSPINE. Several candidate models were fitted for the multiclass classification problem. After comparative analysis, the multinomial regression model was chosen with one-vs-rest area under the curve (AUC) of 0.903 (95% CI, 0.836-0.943) and was able to discriminate between bony and ligamentous injury. PEDSPINE and PEDSPINE II models' ability to identify CSI were compared. In predicting the presence of any injury, PEDSPINE II obtained a one-vs-rest AUC of 0.885 (95% CI, 0.804-0.934), outperforming the PEDSPINE score (AUC, 0.845; 95% CI, 0.769-0.915). Conclusion and Relevance: This study found wide clinical variability in the evaluation of pediatric trauma patients with increased use of cervical spine imaging. This has implications of increased cost, increased radiation exposure, and a potential for overdiagnosis. This prediction tool could help to decrease the use of imaging, aid in clinical decision-making, and decrease hospital resource use and cost.

Are trauma surgeons prepared? A survey of trauma surgeons' disaster preparedness before and during the COVID-19 pandemic.

Objective: US trauma centers (TCs) must remain prepared for mass casualty incidents (MCIs). However, trauma surgeons may lack formal MCI training. The recent COVID-19 pandemic drove multiple patient surges, overloaded Emergency Medical Services (EMS) agencies, and stressed TCs. This survey assessed trauma surgeons' MCI training, experience, and system and personal preparedness before the pandemic compared with the pandemic's third year. Methods: Survey invitations were emailed to all 1544 members of the American Association for the Surgery of Trauma in 2019, and then resent in 2022 to 1575 members with additional questions regarding the pandemic. Questions assessed practice type, TC characteristics, training, experience, beliefs about personal and hospital preparedness, likelihood of MCI scenarios, interventions desired from membership organizations, and pandemic experiences. Results: The response rate was 16.7% in 2019 and 12% in 2022. In 2022, surgeons felt better prepared than their hospitals for pandemic care, mass shootings, and active shooters, but remained feeling less well prepared for cyberattack and hazardous material events, compared with 2019. Only 35% of the respondents had unintentional MCI response experience in 2019 or 2022, and even fewer had experience with intentional MCI. 78% had completed a Stop the Bleed (STB) course and 63% own an STB kit. 57% had engaged in family preparedness activities; less than 40% had a family action plan if they could not come home during an MCI. 100% of the respondents witnessed pandemic-related adverse events, including colleague and coworker illness, patient surges, and resource limitations, and 17% faced colleague or coworker death. Conclusions: Trauma surgeons thought that they became better at pandemic care and rated themselves as better prepared than their hospitals for MCI care, which is an opportunity for them to take greater leadership roles. Opportunities remain to improve surgeons' family and personal MCI preparedness. Surgeons' most desired professional organization interventions include advocacy, national standards for TC preparedness, and online training. Level of evidence: VII, survey of expert opinion.

Association of Transport Time, Proximity, and Emergency Department Pediatric Readiness With Pediatric Survival at US Trauma Centers.

Importance: Emergency department (ED) pediatric readiness is associated with improved survival among children. However, the association between geographic access to high-readiness EDs in US trauma centers and mortality is unclear. Objective: To evaluate the association between the proximity of injury location to receiving trauma centers, including the level of ED pediatric readiness, and mortality among injured children. Design, Setting, and Participants: This retrospective cohort study used a standardized risk-adjustment model to evaluate the association between trauma center proximity, ED pediatric readiness, and in-hospital survival. There were 765 trauma centers (level I-V, adult and pediatric) that contributed data to the National Trauma Data Bank (January 1, 2012, through December 31, 2017) and completed the 2013 National Pediatric Readiness Assessment (conducted from January 1 through August 31, 2013). The study comprised children aged younger than 18 years who were transported by ground to the included trauma centers. Data analysis was performed between January 1 and March 31, 2022. Exposures: Trauma center proximity within 30 minutes by ground transport and ED pediatric readiness, as measured by weighted pediatric readiness score (wPRS; range, 0-100; quartiles 1 [low readiness] to 4 [high readiness]). Main Outcomes and Measures: In-hospital mortality. We used a patient-level mixed-effects logistic regression model to evaluate the association of transport time, proximity, and ED pediatric readiness on mortality. Results: This study included 212 689 injured children seen at 765 trauma centers. The median patient age was 10 (IQR, 4-15) years, 136 538 (64.2%) were male, and 127 885 (60.1%) were White. A total of 4156 children (2.0%) died during their hospital stay. The median wPRS at these hospitals was 79.1 (IQR, 62.9-92.7). A total of 105 871 children (49.8%) were transported to trauma centers with high-readiness EDs (wPRS quartile 4) and another 36 330 children (33.7%) were injured within 30 minutes of a quartile 4 ED. After adjustment for confounders, proximity, and transport time, high ED pediatric readiness was associated with lower mortality (highest-readiness vs lowest-readiness EDs by wPRS quartiles: adjusted odds ratio, 0.65 [95% CI, 0.47-0.89]). The survival benefit of high-readiness EDs persisted for transport times up to 45 minutes. The findings suggest that matching children to trauma centers with high-readiness EDs within 30 minutes of the injury location may have potentially saved 468 lives (95% CI, 460-476 lives), but increasing all trauma centers to high ED pediatric readiness may have potentially saved 1655 lives (95% CI, 1647-1664 lives). Conclusions and Relevance: These findings suggest that trauma centers with high ED pediatric readiness had lower mortality after considering transport time and proximity. Improving ED pediatric readiness among all trauma centers, rather than selective transport to trauma centers with high ED readiness, had the largest association with pediatric survival. Thus, increased pediatric readiness at all US trauma centers may substantially improve patient outcomes after trauma.

Prehospital and emergency department pediatric readiness for injured children: A statement from the American College of Surgeons Committee on Trauma Emergency Medical Services Committee.

ABSTRACT: Injury is the leading cause of death in children older than 1 year, and children make up 22% of the population. Pediatric readiness (PR) of the nation's emergency departments and state trauma and emergency medical services (EMS) systems is conceptually important and vital to mitigate mortality and morbidity in this population. The extension of PR to the trauma community has become a focused area for training, staffing, education, and equipment at all levels of trauma center designation, and there is evidence that a higher level of emergency department PR is independently associated with long-term survival among injured children. Although less well studied, there is an associated need for EMS PR, which is relevant to the injured child who needs assessment, treatment, triage, and transport to a trauma center. We outline a blueprint along with recommendations for incorporating PR into trauma system development in this opinion from the EMS Committee of the American College of Surgeons Committee on Trauma. These recommendations are particularly pertinent in the rural and underserved areas of the United States but are directed toward all levels of professionals who care for an injured child along the trauma continuum of care.

Evolution of the American College of Surgeons Children's Surgery Verification Program: Implications for optimizing multidisciplinary surgical care of the pediatric patient.

The Children's Surgery Verification Program of the American College of Surgeons began in 2016 based on the standards created by the Task Force for Children's Surgery. This program seeks to improve the surgical care of children by assuring the appropriate resources and robust performance improvement programs at participating centers. Three levels of centers with defined scopes of practice and matching resources are defined. Since its inception more than 50 center have been verified. A specialty hospital program was launched in 2019. The standards for all hospitals were revised in 2021 based on lessons learned. In this article the leaders of the program discuss the development, areas of greatest impact and future directions of the program.

Children's surgery verification and value-based care in pediatric surgery.

With the prevailing focus on increasing value in healthcare, understanding the different components of the value equation is of primary importance. Michael E. Porter's writings on the value agenda and the use of integrated practice units (IPUs) have provided easy correlation to adult disease entities with large populations sharing common pathways and providers in the diagnosis and care of these patients. In pediatric surgery, with smaller populations and larger numbers of rare or unique conditions and anatomic challenges, utilizing the concept of an IPU is more challenging. The literature has generally shown the improvements in quality of care through participation in various programs through the American College of Surgeons (ACS) such as trauma verification, or the National Surgical Quality Improvement Project (NSQIP), but that participation alone does not guarantee better outcomes. Use of these programs in conjunction with participation in quality collaboratives have tended to show favorable returns on investment for these programs. We seek to demonstrate how the Children's Surgery Verification (CSV) program provides pediatric surgeons an effective vehicle with which to engage the value agenda, evaluating and improving care over the care continuum in order to improve the function of children's hospitals as larger integrated units.

Evaluating the Regional Differences in Pediatric Injury Patterns During the COVID-19 Pandemic.

INTRODUCTION: Reports of pediatric injury patterns during the COVID-19 pandemic are conflicting and lack the granularity to explore differences across regions. We hypothesized there would be considerable variation in injury patterns across pediatric trauma centers in the United States. MATERIALS AND METHODS: A multicenter, retrospective study evaluating patients <18 y old with traumatic injuries meeting National Trauma Data Bank criteria was performed. Patients injured after stay-at-home orders through September 2020 ("COVID" cohort) were compared to "Historical" controls from an averaged period of equivalent dates in 2016-2019. Differences in injury type, intent, and mechanism were explored at the site level. RESULTS: 47,385 pediatric trauma patients were included. Overall trauma volume increased during the COVID cohort compared to the Historical (COVID 7068 patients versus Historical 5891 patients); however, some sites demonstrated a decrease in overall trauma of 25% while others had an increase of over 33%. Bicycle injuries increased at every site, with a range in percent change from 24% to 135% increase. Although the greatest net increase was due to blunt injuries, there was a greater relative increase in penetrating injuries at 7/9 sites, with a range in percent change from a 110% increase to a 69% decrease. CONCLUSIONS: There was considerable discrepancy in pediatric injury patterns at the individual site level, perhaps suggesting a variable impact of the specific sociopolitical climate and pandemic policies of each catchment area. Investigation of the unique response of the community during times of stress at pediatric trauma centers is warranted to be better prepared for future environmental stressors.
