Pediatric versus adult paradigms for management of adolescent injuries within a regional trauma system

Management of Pediatric Solid Organ Injuries

Solid organ injury (SOI) is common in children who experience abdominal trauma, and the management of such injuries has evolved significantly over the past several decades. In 2000, the American Pediatric Surgical Association (APSA) published the first societal guidelines for the management of blunt spleen and/or liver injury (BLSI), advocating for optimized resource utilization while maintaining patient safety. Nonoperative management (NOM) has become the mainstay of treatment for SOI, and since the publication of the APSA guidelines, numerous groups have evaluated how invasive procedures, hospitalization, and activity restrictions may be safely minimized in children with SOI. Here, we review the current evidence-based management guidelines in place for the treatment of injuries to the spleen, liver, kidney, and pancreas in children, including initial evaluation, inpatient management, and long-term care, as well as gaps that exist in the current literature that may be targeted for further optimization of protocols for pediatric SOI.

Pediatric vs Adult or Mixed Trauma Centers in Children Admitted to Hospitals Following Trauma: A Systematic Review and Meta-Analysis

Importance

Adult trauma centers (ATCs) have been shown to decrease injury mortality and morbidity in major trauma, but a synthesis of evidence for pediatric trauma centers (PTCs) is lacking.

Objective

To assess the effectiveness of PTCs compared with ATCs, combined trauma centers (CTCs), or nondesignated hospitals in reducing mortality and morbidity among children admitted to hospitals following trauma.

Data Sources

MEDLINE, Embase, and Web of Science through March 2023.

Study Selection

Studies comparing PTCs with ATCs, CTCs, or nondesignated hospitals for pediatric trauma populations (aged ≤19 years).

Data Extraction and Synthesis

This systematic review and meta-analysis was performed following the Preferred Reporting Items for Systematic Review and Meta-analysis and Meta-analysis of Observational Studies in Epidemiology guidelines. Pairs of reviewers independently extracted data and evaluated risk of bias using the Risk of Bias in Nonrandomized Studies of Interventions tool. A meta-analysis was conducted if more than 2 studies evaluated the same intervention-comparator-outcome and controlled minimally for age and injury severity. Subgroup analyses were planned for age, injury type and severity, trauma center designation level and verification body, country, and year of conduct. Grading of Recommendations Assessment, Development, and Evaluation (GRADE) was used to assess certainty of evidence.

Main Outcome(s) and Measure(s)

Primary outcomes were mortality, complications, functional status, discharge destination, and quality of life. Secondary outcomes were resource use and processes of care, including computed tomography (CT) and operative management of blunt solid organ injury (SOI).

Results

A total of 56 studies with 286 051 participants were included overall, and 34 were included in the meta-analysis. When compared with ATCs, PTCs were associated with a 41% lower risk of mortality (OR, 0.59; 95% CI, 0.46-0.76), a 52% lower risk of CT use (OR, 0.48; 95% CI, 0.26-0.89) and a 64% lower risk of operative management for blunt SOI (OR, 0.36; 95% CI, 0.23-0.57). The OR for complications was 0.80 (95% CI, 0.41-1.56). There was no association for mortality for older children (OR, 0.71; 95% CI, 0.47-1.06), and the association was closer to the null when PTCs were compared with CTCs (OR, 0.73; 95% CI, 0.53-0.99). Results remained similar for other subgroup analyses. GRADE certainty of evidence was very low for all outcomes.

Conclusions and Relevance

In this systematic review and meta-analysis, results suggested that PTCs were associated with lower odds of mortality, CT use, and operative management for SOI than ATCs for children admitted to hospitals following trauma, but certainty of evidence was very low. Future studies should strive to address selection and confounding biases.

Between paradigms: Comparing experiences for adolescents treated at pediatric and adult trauma centres

INTRODUCTION

Injured adolescents may be treated at pediatric trauma centres (PTCs) or adult trauma centres (ATCs). Patient and parent experiences are an integral component of high-quality health care and can influence patient clinical trajectory. Despite this knowledge, there is little research on differences between PTCs and ATCs with respect to patient and caregiver-reported experience. We sought to identify differences in patient and parent-reported experiences between the regional PTC and ATC using a recently developed Patient and Parent-Reported Experience Measure.

METHODS

We prospectively enrolled patients (caregivers) aged 15-17 (inclusive), admitted to the local PTC and ATC for injury management (01/01/2020 - 31/05/2021) We provided a survey 8-weeks post-discharge to query acute care and follow-up experience. Patient and parent experiences were compared between the PTC and ATC using descriptive statistics, chi-square tests for categorical and independent t-tests for continuous variables.

RESULTS

We identified 90 patients for inclusion (51 PTC, and 39 ATC). From this population, we had 77 surveys (32 patient and 35 caregiver) completed at the PTC, and 41 (20 patient and 21 caregiver) at the ATC. ATC patients tended to be more severely injured. We identified few differences in reported experience on the patient measure but identified lower ratings from caregivers of adolescents treated in ATCs for the domains of information and communication, follow-up care, and overall hospital scores. Patients and parents reported poorer family accommodation at the ATC.

CONCLUSION

Patient experiences were similar between centres. However, caregivers report poorer experiences at the ATC in several domains. These differences are multifaceted, and may reflect differing patient volumes, effects of COVID-19, and healthcare paradigms. However, further work should target information and communication improvement in adult paradigms given its impact on other domains of care.

Computed tomography rates in pediatric trauma patients among emergency medicine and pediatric emergency medicine physicians

BACKGROUND

Pediatric trauma patients undergo fewer computed tomography (CT) scans when evaluated at pediatric trauma centers (PTC) versus adult trauma centers (ATC) with no change in clinical outcome. Factors contributing to this difference are unclear. We sought to identify whether the training background of physicians, specifically emergency medicine (EM) versus pediatric emergency medicine (PEM), affected the CT rate of pediatric trauma patients within one institution.

METHODS

A single-center retrospective study of CT utilization based on attending physicians' training in trauma patients <18 years between November 2018 and November 2020. Attendings were categorized into two groups: EM residency with no PEM fellowship, or pediatrics/EM residency with PEM fellowship. Primary outcomes measured were the proportion of patients receiving a CT and CT positivity rate.

RESULTS

Of 463 study patients, CTs were obtained in 145/228 (64%) patients by EM, and 130/235 (55%) by PEM (p=.07). CT positivity rate was 21% and 19% in EM and PEM, respectively (p=.46). The mean number of CTs per patient in EM was 2.8 compared to 2.1 in PEM (p<.01), and for patients with an injury severity score (ISS) >15, mean number of CTs per patient increased to 4.9 in EM versus 2.4 in PEM (p=.01).

CONCLUSIONS

The mean number of CTs ordered per patient was statistically higher for EM attendings. The differences between CT rates highlight future opportunities for ongoing development of pediatric trauma imaging guidelines and radiation exposure reduction.

LEVELS OF EVIDENCE

Retrospective Study, Level III.

Social determinants of health as drivers of inequities in pediatric injury

A child's social determinants of health (SDH), including their neighborhood environment, insurance status, race and ethnicity, English language proficiency and geographic location, all significantly impact their risk of injury and outcomes after injury. Children from socioeconomically disadvantaged neighborhoods experience overall higher rates of injury and different types of injuries, including higher rates of motor vehicle-, firearm-, and violence-related injuries. Similarly, children with public insurance or no insurance, as a proxy for lower socioeconomic status, experience higher rates of injuries including firearm-related injuries and non-accidental trauma, with overall worse outcomes. Race and associated racism also impact a child's risk of injury and care received after injury. Black children, Hispanic children, and those from other minority groups disproportionately experience socioeconomic disadvantage with sequelae of injury risk as described above. Even after controlling for socioeconomic status, there are still notable disparities with further evidence of racial inequities and bias in pediatric trauma care after injury. Finally, where a child lives geographically also significantly impacts their risk of injury and available care after injury, with differences based on whether a child lives in a rural or urban area and the degree of state laws regarding injury prevention. There are clear inequities based on a child's SDH, most predominantly in a child's risk of injury and the types of injuries they experience. These injuries are preventable and the SDH provide potential upstream targets in injury prevention efforts.

Pediatric traumatic brain injury: Resource utilization and outcomes at adult versus pediatric trauma centers

INTRODUCTION

Traumatic brain injury is the leading cause of trauma-related death in children. We hypothesized that children with isolated traumatic brain injury would experience differential outcomes when treated at pediatric versus adult or combined trauma centers.

METHODS

After institutional review board approval, the 2015 National Trauma Data Bank was queried for children up to age 16 years with isolated traumatic brain injury. Demographics and clinical outcomes were collected. Univariable and multivariable analyses were conducted to assess for predictors of in-hospital mortality and complications. Kaplan-Meier survival analysis was conducted.

RESULTS

A total of 3,766 children with isolated traumatic brain injury were identified; 1,060 (28%) were treated at pediatric trauma centers, 1,909 (51%) at adult trauma centers, and 797 (21%) at combined trauma centers. Subjects were 5 years old (median, interquartile range 1-12 years), 63% male, and 64% white. Higher blood pressure and lower injury severity score were associated with reduced mortality (P < .05). Increasing injury severity score was associated with higher mortality by multivariable logistic regression (odds ratio 1.57, P < .0001). There were no survival differences among hospital types (P = .88).

CONCLUSION

Outcomes for children with isolated traumatic brain injury appear equal across different types of designated trauma centers. These findings may have implications for prehospital transport and triage guidelines.
