A 15 year cohort review of in-hospital pediatric trauma center mortality: A catalyst for injury prevention programming

Child maltreatment mortality in Canada: An analysis of coroner and medical examiner data

BACKGROUND

Fatalities are the most severe consequence of child maltreatment, but there are gaps in what is known about the epidemiology of such deaths in Canada.

OBJECTIVES

The objectives of this study were to: (1) identify child maltreatment deaths among those classified as homicide or undetermined manner; (2) estimate rates of child maltreatment mortality by sex, age, geography, and year; and (3) measure differences between rates of child maltreatment mortality and homicide mortality.

METHODS

We used a cross-sectional design and analyzed mortality data from the Canadian Coroner and Medical Examiner Database for a ten-year period (2007 to 2016). To identify child maltreatment deaths, we reviewed narrative data about children aged 0 to 17 years old whose deaths were classified as homicide or undetermined. Descriptive statistics, mortality rates, and incidence rate ratios were calculated.

RESULTS

Among the 1758 child deaths due to homicide or an undetermined manner, maltreatment was the probable cause in 20.4 % (n = 359) of deaths; most child maltreatment deaths (72.1 %, n = 259) were among children younger than 5 years old. The national child maltreatment mortality rate was 0.55 deaths per 100,000; the rate was highest among infants (3.43 per 100,000) and decreased at older ages.

CONCLUSION

This study provides evidence about the epidemiology of child maltreatment mortality in Canada.

Correlation between early computed tomography findings and neurological outcome in pediatric traumatic brain injury patients

Traumatic brain injury (TBI) is a leading cause of morbidity and mortality in children. Head computed tomography (CT) is frequently utilized for evaluating trauma-related characteristics, selecting treatment options, and monitoring complications in the early stages. This study assessed the relationship between cranial CT findings and early and late neurological outcomes in pediatric TBI patients admitted to the pediatric intensive care unit (PICU). The study included children aged 1 month to 18 years who were admitted to the PICU due to TBI between 2014 and 2020. Sociodemographic data, clinical characteristics, and cranial CT findings were analyzed. Patients were categorized based on their Glasgow Coma Scale (GCS) score. Of the 129 patients, 83 (64%) were male, and 46 (36%) were female, with a mean age of 6.8 years. Falls (n = 51, 39.5%) and in-vehicle traffic accidents (n = 35, 27.1%) were the most common trauma types observed. Normal brain imaging findings were found in 62.7% of the patients, while 37.3% exhibited intracranial pathology. Hemorrhage was the most frequent CT finding. Severe TBI (n = 26, p = 0.032) and mortality (n = 9, p = 0.017) were more prevalent in traffic accidents. The overall mortality rate in the study population was 10.1%. In children with TBI, cranial CT imaging serves as an essential initial method for patients with neurological manifestations. Particularly, a GCS score of ≤ 8, multiple hemorrhages, diffuse cerebral edema, and intraventricular bleeding are associated with sequelae and mortality.

Epidemiology and factors associated with mortality among pediatric major trauma patients in Nova Scotia: A 17-year retrospective analysis

BACKGROUND

Major traumatic injury in the pediatric population requires further evaluation to improve patient outcomes. Relatively few Canadian studies have investigated pediatric trauma using population-based data. Our objectives were to describe the epidemiology of pediatric major trauma in Nova Scotia and identify factors associated with in-hospital mortality.

METHODS

Retrospective cohort study of pediatric major trauma patients (age <18 years) injured in Nova Scotia over a 17-year period (April 2001-March 2018). Data were collected from the Nova Scotia Trauma Registry. Characteristics were compared between patient subgroups using t-tests, chi-square analyses and Fisher's exact test. Temporal trends were evaluated using the Mann-Kendall test. Incidence and mortality rates were mapped using ArcGIS Pro. A multivariate logistic regression model was created to assess for factors associated with in-hospital mortality.

RESULTS

A total of 1258 injuries were observed over the 17-year study period. The incidence of pediatric major trauma was 41.7 per 100,000 person-years. Most patients were male (819/1258; 65.1 %) and resided in urban areas (764/1258; 60.7 %). Blunt trauma accounted for 86.2 % (1084/1258) of injuries, and motor vehicle collisions were the most common cause (448/1258; 35.6 %). Incidence and mortality rates were highest in the 15-17 year age group, with a trend towards increasing incidence among females (p = 0.011). Mortality was 17.2 % (217/1258) of patients; 10.9 % (137/1258) died pre-hospital. No trends were detected in mortality rates. The regression model showed increased odds of in-hospital mortality for every point increase in the ISS (OR 1.05; 95 % CI 1.02 to 1.09) and for every unit decrease in scene GCS (OR 0.63; 95 % CI 0.56-0.71). Rural patients were 2 times more likely to die in-hospital versus urban patients (OR 2.40; 95 % CI 1.01-5.69), and patients injured at home were 6 times more likely to die compared to those injured in other locations (OR 6.19; 95 % CI 1.01-38.11).

CONCLUSION

Pediatric trauma remains a major public health issue in Canada and beyond. Greater efforts are required to expand our understanding of trauma epidemiology and develop targeted injury prevention strategies, especially for rural inhabitants.

Pediatric Pedestrian Injuries: Striking Too Close to Home

BACKGROUND

Pediatric pedestrian injuries (PPI) are a major public health concern. This study utilized geospatial analysis to characterize the risk and injury severity of PPI.

METHODS

A retrospective chart review of PPI patients (age < 18) from a level 1 trauma center was performed (2013-2020). A geographic information system geocoded injury location to home and other public landmarks. Incidents were aggregated to zip codes and the Local Indicators of Spatial Association statistic tested for spatial clustering of injury rates per 10,000 children. Predictors for increased injury severity were assessed by logistic regression.

RESULTS

PPI encompassed 6% (n = 188) of pediatric traumas. Most patients were black (54%), male (58%), >13 years (56%), and with Medicaid insurance (68%). Nine zip codes comprised a statistically significant cluster of PPI. Nearly half (40%) occurred within a quarter mile of home; 7% occurred at home. Most (65%) PPI occurred within 1 mile of a school, and 45% occurred within a quarter mile of a park. Nearly all (99%) PPI occurred within a quarter mile of a major intersection and/or roadway. Using admission to ICU as a marker for injury severity, farther distance from home (OR 1.060, 95% CI 1.001-1.121, p = 0.045) and age <13 years (3.662, 95% CI 1.854-7.231, p < 0.001) were independent predictors of injury severity.

CONCLUSIONS

There are significant sociodemographic disparities in PPI. Most injuries occur near patients' homes and other public landmarks. Multidisciplinary injury prevention collaboration can help inform policymakers, direct local safety programs, and provide a model for PPI prevention at the national level.

Epidemiology of major paediatric trauma in a European Country - trends of a decade

OBJECTIVES

This study investigates causes, characteristics and temporal trends of paediatric major trauma over a 10-year period and assesses potential preventive areas.

METHODS

Single-centre retrospective study of paediatric trauma patients admitted to a Paediatric Intensive Care Unit (PICU) in a tertiary university hospital in Europe with a level 1 paediatric trauma centre, from 2009 to 2019. Paediatric major trauma patients were defined as patients aged < 18 years with Injury Severity Score > 12, admitted for intensive care for more than 24 h following trauma. Demographic, social and clinical information, including place and mechanism of trauma, injury pattern, pre-hospital and in-hospital procedures, and length of stay in PICU was extracted from PICU medical records.

RESULTS

Total 358 patients included (age 11 ± 4,9 years; 67% male); 75% were involved in road traffic accidents: 30% motor vehicle collision, 25% pedestrian, 10% motorcycle and bicycle each. Falls from height injured 19% of children, 4% during sports activities. Main injuries were to head/neck (73%) and extremities (42%). The incidence of major trauma was highest in teenagers and did not show a decreasing trend during the study years. All fatalities (1,7%; n = 6) were related to head/neck injuries. Motor vehicle collisions resulted in higher need for blood transfusion (9 vs. 2 mL/kg, p = 0,006) and the highest ICU-mortality (83%; n = 5). Children in motorcycle accidents had longer ICU length-of-stay (6,4 vs. 4,2 days, p = 0,036). Pedestrians had 25% higher risk of head/neck injuries (RR 1,25; 1,07 - 1,46; p = 0,004), and higher incidence of severe brain injury (46% vs. 34%, p = 0,042). Most children in motor-vehicle/bicycle accidents were not using restraints/protective devices (45%) or were using them inappropriately (13%).

CONCLUSIONS

Over the last decade, the absolute numbers of paediatric major trauma did not decrease. Road traffic accidents remain the leading cause of injury and death. Teenagers are at highest risk for severe trauma. Appropriate use of child restraints and protective equipment remain key for prevention.

The characteristics, management and outcomes of high- and low-grade renal injuries in paediatric trauma patients at a major trauma centre

Introduction

Children, given anatomical variations, are at increased risk of renal injury following trauma. The management of paediatric renal injuries has, similar to other solid organ injuries, largely shifted towards conservative management; however, hemodynamically unstable patients may still warrant surgical exploration or interventional techniques. The aim of this study is to describe the local incidence, demographics, morbidity and outcomes associated with high- and low-grade renal injury in a paediatric major trauma population.

Method

This was a 5-year retrospective review of trauma registry data and chart analysis of all paediatric renal injuries from major trauma at a North American level 1 paediatric trauma centre between January 2016–31 December 2020. Data was analysed using SPSS v27 with p < 0.05 considered significant.

Results

Of 1334 major trauma patients, 45 suffered a kidney injury (20 high-grade and 25 low-grade injuries), of which 93.3% underwent conservative management with no difference in outcomes between groups. 80% of patients had concurrent injuries (a quarter requiring surgery for these), with a trend towards higher rates of chest injuries in high-grade renal injury patients ( p = 0.08). Bicycle injuries were statistically more likely to cause high-grade renal injury ( p = 0.02). Angiography was utilized infrequently (3/45 patients, 6.6%), and no patients underwent embolization in our study population. Overall mortality (4.4%) and length of stay were unaffected by grade of injury.

Conclusion

Paediatric renal injury is an uncommon injury in major trauma patients (3.4%). Most cases can be managed conservatively regardless of the grade of injury. Renal injury patients are likely to have concurrent injuries, often requiring surgery. Further studies are needed to measure the success and utilization of interventional radiology techniques for management in children.

Traumatic Pediatric Fatalities: Are They Preventable?

INTRODUCTION

Trauma related injury remains the leading cause of mortality in pediatric patients, many of which are preventable. The goal of our study was to identify the mechanism of injury (MOI) in pediatric trauma-related fatalities and determine if these injuries were preventable to direct future injury prevention efforts within trauma programs.

METHODS

After IRB approval, a retrospective, single-institution review of pediatric (age ≤18) trauma fatalities from 2010 to 2019 was performed. MOI, use of protective devices, demographics, and whether the injury was preventable were collected. Patients were divided into five age cohorts, and frequencies and proportions were used to summarize data. Bivariate testing was done using Fisher's exact and Monte Carlo estimates for the exact test.

RESULTS

MOI was found to vary by age with non-accidental trauma found to be the most common cause of trauma related deaths in children <1 (88.5%) and 1-4 (33.3%). MVC was the most common MOI in children >5 y, with 68.4% in the 5-9, 34.4% in the 10-14, and 45.8% in the 15-18 age group. The majority of fatalities resulted from a preventable injury (P < 0.0001) in the younger children with a negative association as age increased: 92.3% <1, 53.3% in 1-4, 36.8% in 5-9, 46.9% in 10-14 and 48.6% in 15-18. Of the preventable injuries, non-accidental trauma was the most common MOI in children <5, while GSW was the most common MOI in children >10.

CONCLUSIONS

This study demonstrates many pediatric fatalities are the result of a preventable traumatic injury. This data can guide focused traumatic injury prevention efforts.

Health Care Resources and 24,910 Deaths Due to Traffic Accidents: An Ecological Mortality Study in Poland

Background: Deaths due to traffic accidents are preventable and the access to health care is an important determinant of traffic accident case fatality. This study aimed to assess the relation between mortality due to traffic accidents and health care resources (HCR), at the population level, in 66 sub-regions of Poland. Methods: An area-based HCR index was delivered from the rates of physicians, nurses, and hospital beds. Associations between mortality from traffic accidents and the HCR index were tested using multivariate Poisson regression models. Results: In the sub-regions studied, the average mortality from traffic accidents was 11.7 in 2010 and 9.3/100.000 in 2015. After adjusting for sex, age and over time trends in mortality, out-of-hospital deaths were more frequently compared to hospitalized fatal cases (incidence rate ratio (IRR) = 1.68, 95% CI 1.45–1.93). Compared to sub-regions with high HCR, mortality from traffic accidents was higher in sub-regions with low and moderate HCR (IRR = 1.25, 95% CI 1.11–1.42 and IRR = 1.19, 95% CI 1.02–1.38, respectively), which reflected the differences in out-of-hospital mortality most pronounced in car accidents. Conclusions: Poor HCR is an important factor that explains the territorial differentiation of mortality due to traffic accidents in Poland. The high percentage of out-of-hospital deaths indicates the importance of preventive measures and the need for improvement in access to health care to reduce mortality due to traffic accidents.

Evidence-Based and Clinically Relevant Outcomes for Hemorrhage Control Trauma Trials

OBJECTIVE

To address the clinical and regulatory challenges of optimal primary endpoints for bleeding patients by developing consensus-based recommendations for primary clinical outcomes for pivotal trials in patients within 6 categories of significant bleeding, (1) traumatic injury, (2) intracranial hemorrhage, (3) cardiac surgery, (4) gastrointestinal hemorrhage, (5) inherited bleeding disorders, and (6) hypoproliferative thrombocytopenia.

BACKGROUND

A standardized primary outcome in clinical trials evaluating hemostatic products and strategies for the treatment of clinically significant bleeding will facilitate the conduct, interpretation, and translation into clinical practice of hemostasis research and support alignment among funders, investigators, clinicians, and regulators.

METHODS

An international panel of experts was convened by the National Heart Lung and Blood Institute and the United States Department of Defense on September 23 and 24, 2019. For patients suffering hemorrhagic shock, the 26 trauma working-group members met for almost a year, utilizing biweekly phone conferences and then an in-person meeting, evaluating the strengths and weaknesses of previous high quality studies. The selection of the recommended primary outcome was guided by goals of patient-centeredness, expected or demonstrated sensitivity to beneficial treatment effects, biologic plausibility, clinical and logistical feasibility, and broad applicability.

CONCLUSIONS

For patients suffering hemorrhagic shock, and especially from truncal hemorrhage, the recommended primary outcome was 3 to 6-hour all-cause mortality, chosen to coincide with the physiology of hemorrhagic death and to avoid bias from competing risks. Particular attention was recommended to injury and treatment time, as well as robust assessments of multiple safety related outcomes.

Ten-Year in-Hospital Mortality Trends among Paediatric Injured Patients in Japan: A Nationwide Observational Study

Injury is a major cause of worldwide child mortality. This retrospective nationwide study aimed to evaluate the characteristics of paediatric injured patients in Japan and their in-hospital mortality trends from 2009 to 2018. Injured patients aged <17 years were enrolled. Data were extracted from the Japan Trauma Data Bank. In the Cochran-Armitage test, in-hospital mortality significantly decreased during the study period (p < 0.001), except among patients <1 year old, and yearly reductions were observed among those with an Injury Severity Score ≥16 and survival rate ≥50% (p < 0.001). In regression analyses, patients who underwent urgent blood transfusion within 24 h after hospital admission (odds ratio (OR) = 3.24, 95% confidence interval (CI) = 2.38–4.41) had a higher in-hospital mortality risk. Higher survival probability as per the Trauma and Injury Severity Score was associated with lower in-hospital mortality (OR = 0.92, 95% CI = 0.91–0.92), a risk which decreased from 2009 to 2018 (OR = 6.16, 95% CI = 2.94–12.88). Based on our results, there is a need for improved injury surveillance systems for establishment of injury prevention strategies along with evaluation of the quality of injury care and outcome measures.

Validation of the PredAHT-2 prediction tool for abusive head trauma

OBJECTIVE

The validated Predicting Abusive Head Trauma (PredAHT) clinical prediction tool calculates the probability of abusive head trauma (AHT) in children <3 years of age who have sustained intracranial injuries (ICIs) identified on neuroimaging, based on combinations of six clinical features: head/neck bruising, seizures, apnoea, rib fracture, long bone fracture and retinal haemorrhages. PredAHT version 2 enables a probability calculation when information regarding any of the six features is absent. We aimed to externally validate PredAHT-2 in an Australian/New Zealand population.

METHODS

This is a secondary analysis of a prospective multicentre study of paediatric head injuries conducted between April 2011 and November 2014. We extracted data on patients with possible AHT at five tertiary paediatric centres and included all children <3 years of age admitted to hospital who had sustained ICI identified on neuroimaging. We assigned cases as positive for AHT, negative for AHT or having indeterminate outcome following multidisciplinary review. The estimated probability of AHT for each case was calculated using PredAHT-2, blinded to outcome. Tool performance measures were calculated, with 95% CIs.

RESULTS

Of 87 ICI cases, 27 (31%) were positive for AHT; 45 (52%) were negative for AHT and 15 (17%) had indeterminate outcome. Using a probability cut-off of 50%, excluding indeterminate cases, PredAHT-2 had a sensitivity of 74% (95% CI 54% t o89%) and a specificity of 87% (95% CI 73% to 95%) for AHT. Positive predictive value was 77% (95% CI 56% to 91%), negative predictive value was 85% (95% CI 71% to 94%) and the area under the curve was 0.80 (95% CI 0.68 to 0.92).

CONCLUSION

PredAHT-2 demonstrated reasonably high point sensitivity and specificity when externally validated in an Australian/New Zealand population. Performance was similar to that in the original validation study.

Epidemiology, Patterns of treatment, and Mortality of Pediatric Trauma Patients in Japan

Limited information exists regarding the epidemiology, patterns of treatment, and mortality of pediatric trauma patients in Japan. To evaluate the characteristics and mortality of pediatric trauma patients in Japan, especially in traffic accidents. This was a retrospective cohort study between 2004 and 2015 from a nationwide trauma registry in Japan. Pediatric trauma patients divided into four age groups: <1 years; 1 ≤ 5 years; 6 ≤ 10 years; and 11 ≤ 15 years. Data on patients' demographics, trauma mechanism and severity, treatments and in-hospital mortality were analyzed between the groups. There were 15,441 pediatric trauma patients during the study period. Among 15,441 pediatric patients, 779 belonged to the <1 year age group, 3,933 to the 1 ≤ 5 years age group, 5,545 to the 6 ≤ 10 age group, and 5,184 to the 11 ≤ 15 years age group. Male injuries (69%) were more frequent than female injuries. Head injuries (44%) were the most frequent and severe. Traffic accidents were the leading cause of trauma (44%). Overall in-hospital mortality was 3.9% and emergency department mortality was 1.4%. In-hospital mortality was 5.3%, 4.7%, 3.0% and 4.0% for the <1 year, 1 ≤ 5 years, 6 ≤ 10 years, and 11 ≤ 15 years age groups respectively. A total of 57% of all trauma deaths were before or upon arrival at hospital. Traffic accidents for the <1 year age group was the highest category of mortality (15%). The overall in-hospital mortality of Japanese pediatric trauma patients was 3.9% based on the nationwide trauma registry of Japan. The main cause of severe trauma was traffic accidents, especially in patients <1 year of age whose mortality was 15%.
