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

Characteristics and clinical outcomes of patients with combined burns and trauma in Japan: Analysis of a nationwide trauma registry database

INTRODUCTION

Patients with combined burns and trauma are often seen in the United States. The combination of trauma with burns increases mortality. In contrast, the characteristics and outcomes of these cases remain unknown in Japan. This study investigated the characteristics and outcomes of trauma associated with burns in Japan.

METHODS

This multicenter retrospective cohort study was conducted by utilizing data from the Japan Trauma Data Bank for the period between 2004 and 2017. We evaluated the characteristics of burn patients (n = 5783) divided into two groups: burns only (n = 5537) and combined burns and trauma (n = 246). Clinical characteristics, including patient background, severity of trauma, injury mechanism, total body surface area affected, injury location, treatments, and clinical outcomes, were examined.

RESULTS

Most patients in both the groups were injured by flames. The number proportion of patients with 40-89% of the total body surface area affected was 1069/5537 (19.3%) in the burn-only group and 23/246 (9.3%) in the combined burn and trauma group. The in-hospital mortality was 1006/5537 (18.2%) in the burn-only group and 17/246 (6.9%) in the combined burn and trauma group.

CONCLUSIONS

We demonstrated the characteristics of Japanese patients with burns only compared with those with combined burns and trauma. Flames were the main cause of burns, and in-hospital mortality was lower in the combined burn and trauma group associated with a smaller burn area.

Analysis of the current usage of resuscitative endovascular balloon occlusion of the aorta (REBOA) in pediatric trauma patients: a retrospective observational study from the American College of Surgeons-Trauma Quality Improvement Program databases

Background

Resuscitative endovascular balloon occlusion of the aorta (REBOA) has been an established life-saving procedure for adult trauma patients, but the evidence for its use in pediatric patients is still under question. The purpose of this study was to examine the outcome of REBOA in pediatric patients.

Methods

We retrospectively analyzed observational cohort data from the American College of Surgeons-Trauma Quality Improvement Program from 2017 to 2019. We analyzed 183 506 trauma patients aged 7-18, and 111 patients were matched by propensity score analysis. Basic demographics, injury severity, trauma type, and clinical outcomes of the patients receiving REBOA and those not receiving REBOA were compared. In the REBOA patients, a subgroup analysis was performed to evaluate the potential influence of age and body weight on the outcomes of REBOA.

Results

After the pretreatment factors were balanced for the REBOA and no-REBOA groups, the patients in the REBOA group had more transfused packed red blood cells within the first 4 hours (3250 mL vs. 600 mL, p<0.001), and the mortality rate was higher in the REBOA group, but it did not reach statistical significance (56.8% vs. 36.5%, p=0.067). No significant difference was detected regarding in-hospital complications. In the subgroup analysis of the patients who received REBOA, we discovered no significant difference in mortality and complications between the subgroups when compared by age (>15 years old/≤15 years old) or weight (>58 kg or ≤58 kg).

Conclusions

Pediatric trauma patients who received REBOA were not significantly associated with an increased risk of mortality when compared with no-REBOA patients with matched basic demographics and pretreatment factors. Younger age and lighter body weight did not seem to influence the outcomes of REBOA regarding survival and complications.

CT in pediatric trauma patients

The decision as to whether to perform a computed tomography (CT) examination in severe pediatric trauma poses a challenge. The therapeutic benefit of computed tomography in injured children is lower compared to adults, while the potential negative effects of ionizing radiation may be higher. Thus, the threshold for CT should be higher. Centers that less frequently treat pediatric cases tend to conduct more whole-body CT examinations than dedicated pediatric trauma centers, indicating a clinical overestimation of injury severity with subsequently unnecessary imaging due to inexperience. On the other hand, a CT scan that is not performed but is actually necessary can also have negative consequences if an injury is detected with a delay. An injured child presents a challenging situation for all involved healthcare providers, and thus requires a structured approach to decision-making.Selective literature review of the benefits and risks of CT in injured children, as well as indications for whole-body and region-specific CT imaging.This article provides an overview of current guidelines, recent insight into radiation protection and the benefits of CT in injured children, and evidence-based decision criteria for choosing the appropriate modality based on the mechanism of injury and the affected body region. · Whole-body CT has less of an influence on treatment decisions and mortality in severely injured children than in adults.. · For radiation protection reasons, the indication should be determined more conservatively in children than in adult trauma patients.. · The indication for CT should ideally be determined separately for each region of the body.. · Ultrasound and MRI are a good alternative for the primary diagnostic workup in many situations.. · Appelhaus S, Schönberg SO, Weis M.

Pediatric trauma patients in Swedish ambulance services -a retrospective observational study of assessments, interventions, and clinical outcomes

BACKGROUND

Pediatric trauma patients constitute a significant portion of the trauma population treated by Swedish Emergency Medical Services (EMS), and trauma remains a notable cause of death among Swedish children. Previous research has identified potential challenges in prehospital assessments and interventions for pediatric patients. In Sweden, there is limited information available regarding pediatric trauma patients in the EMS. The aim of this study was to investigate the prevalence of pediatric trauma patients within the Swedish EMS and describe the prehospital assessments, interventions, and clinical outcomes.

METHODS

This retrospective observational study was conducted in a region of Southwestern Sweden. A random sample from ambulance and hospital records from the year 2019 was selected. Inclusion criteria were children aged 0-16 years who were involved in trauma and assessed by EMS clinicians.

RESULTS

A total of 440 children were included in the study, representing 8.4% of the overall trauma cases. The median age was 9 years (IQR 3-12), and 60.5% were male. The leading causes of injury were low (34.8%) and high energy falls (21%), followed by traffic accidents. The children were assessed as severely injured in 4.5% of cases. A quarter of the children remained at the scene after assessment. Complete vital signs were assessed in 29.3% of children, and 81.8% of children were assessed according to the ABCDE structure. The most common intervention performed by prehospital professionals was the administration of medication. The mortality rate was 0.2%.

CONCLUSIONS

Pediatric trauma cases accounted for 8.4% of the overall trauma population with a variations in injury mechanisms and types. Vital sign assessments were incomplete for a significant proportion of children. The adherence to the ABCDE structure, however, was higher. The children remained at the scene after assessment requires further investigation for patient safety.

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.

Mortality after paediatric emergency calls for patients with or without pre-existing comorbidity: a nationwide population based cohort study

BACKGROUND

Life-threatening conditions are infrequent in children. Current literature in paediatric prehospital research is centred around trauma and paediatric out-of-hospital cardiac arrests (POHCA). The aims of this study were to (1) outline the distribution of trauma, POHCA or other medical symptoms among survivors and non-survivors after paediatric emergency calls, and (2) to investigate these clinical presentations' association with mortality in children with and without pre-existing comorbidity, respectively.

METHODS

Nationwide population-based cohort study including ground and helicopter emergency medical services in Denmark for six consecutive years (2016-2021). The study included all calls to the emergency number 1-1-2 regarding children ≤ 15 years (N = 121,230). Interhospital transfers were excluded, and 1,143 patients were lost to follow-up. Cox regressions were performed with trauma or medical symptoms as exposure and 7-day mortality as the outcome, stratified by 'Comorbidity', 'Severe chronic comorbidity' and 'None' based on previous healthcare visits.

RESULTS

Mortality analysis included 76,956 unique patients (median age 5 (1-12) years). Annual all-cause mortality rate was 7 per 100,000 children ≤ 15 years. For non-survivors without any pre-existing comorbidity (n = 121), reasons for emergency calls were trauma 18.2%, POHCA 46.3% or other medical symptoms 28.9%, whereas the distribution among the 134 non-survivors with any comorbidity was 7.5%, 27.6% and 55.2%, respectively. Compared to trauma patients, age- and sex-adjusted hazard ratio for patients with calls regarding medical symptoms besides POHCA was 0.8 [0.4;1.3] for patients without comorbidity, 1.1 [0.5;2.2] for patients with comorbidity and 6.1 [0.8;44.7] for patients with severe chronic comorbidity.

CONCLUSION

In both non-survivors with and without comorbidity, a considerable proportion of emergency calls had been made because of various medical symptoms, not because of trauma or POHCA. This outline of diagnoses and mortality following paediatric emergency calls can be used for directing paediatric in-service training in emergency medical services.

Epidemiological and clinical characteristics of hospitalized unintentional injuries among children in central China from 2017-2023

Objectives

To examine the epidemiological and clinical characteristics of hospitalized unintentional injuries among children in Central China and theoretically propose preventive and control measures.

Methods

We conducted a retrospective study of children aged 0-18 years with unintentional injuries who were admitted to a tertiary hospital in Central China from January 2017 to December 2023. We examined various aspects of the unintentional injuries, including age, gender, urban-rural distribution, external causes, trends, location of injury, cost, and length of stay.

Results

A total of 20,166 children with hospitalized unintentional injuries were enrolled. The median age with IQR was 2.8 (1.6, 5.1) years, with majority of the patients (57.0%) were aged 1-3 years, while the fewest were aged 11-18 years. The male-to-female ratio was 1.8:1, and the urban-to-rural ratio was 1.1:1. The most common external causes were foreign bodies (41.7%), exposure to inanimate mechanical forces (25.1%), and falls (22.1%). The most frequently injured body parts were head (72.5%). The total number of unintentional injuries exhibited an increasing trend from 2017-2022, and a decreasing trend from 2022-2023. The urban-rural distribution reversed after 2020. The overall hospitalization cost was 20,810,870.4 USD, with an median cost of 758.7 (556.4, 1,186.2) USD per person.

Conclusion

Unintentional injuries imposed a heavy burden on society and families. However, the number of cases and the urban-rural distribution showed significant trend changes from 2017-2023. The external causes varied by age group, gender, and region, while prevention and control measures should be developed accordingly.

Association Between Whole Blood Transfusion and Mortality Among Injured Pediatric Patients

OBJECTIVE

The aim of this study was to assess the association between whole blood (WB) and mortality among injured children who received immediate blood transfusion.

BACKGROUND

The use of WB for transfusion therapy in trauma has been revisited, and recent studies have reported an association between WB and improved survival among adults. However, evidence of a similar association lacks in children.

METHODS

We performed a retrospective cohort study from the American College of Surgeons Trauma Quality Improvement Program (ACS-TQIP) between 2020 and 2021. Patients were aged less than or equal to 16 years and had immediate blood transfusion within 4 hours of hospital arrival. Survival at 24 hours and 30 days were compared after creating 1:1 propensity score-matched cohorts, matching for demographics, injury type, vital signs on admission, trauma severity scores, hemorrhage control procedures, hospital characteristics, and the need for massive transfusion.

RESULTS

A total of 2729 patients were eligible for analysis. The median age was 14 years (interquartile range: 8-16 years); 1862 (68.2%) patients were male; and 1207 (44.2%) patients were White. A total of 319 (11.7%) patients received WB. After a 1:1 ratio propensity score matching, 318 matched pairs were compared. WB transfusion was associated with improved survival at 24 hours, demonstrating a 42% lower risk of mortality (hazard ratio, 0.58; 95% CI, 0.34-0.98; P =0.042) Similarly, the survival benefit associated with WB transfusion remained consistent at 30 days (hazard ratio, 0.65; 95% CI, 0.46-0.90; P =0.011).

CONCLUSION

The use of WB was associated with improved survival among injured pediatric patients requiring immediate transfusion.

Mechanical trauma in children and adolescents in Berlin

Management of severe pediatric trauma remains challenging. Injury patterns vary according to patient age and trauma mechanism. This study analyzes trauma mechanisms in deceased pediatric patients. Fatal pediatric trauma cases aged 0-18 years who underwent forensic autopsy in the Federal State of Berlin, Germany, between 2008 until 2018 were enrolled in this retrospective study. Autopsy protocols were analyzed regarding demographic characteristics, trauma mechanisms, injury patterns, resuscitation measures, survival times as well as place, and cause of death. 71 patients (73% male) were included. Traffic accidents (40%) were the leading cause of trauma, followed by falls from height > 3 m (32%), railway accidents (13%), third party violence (11%) and other causes (4%). While children under 14 years of age died mostly due to traumatic brain injury (59%), polytrauma was the leading cause of death in patients > 14 years (55%). Other causes of death were hemorrhage (9%), thoracic trauma (1%) or other (10%). A suicidal background was proven in 24%. In the age group of > 14 years, 40% of all mortalities were suicides. Cardiopulmonary resuscitation was carried out in 39% of all patients. 42% of the patients died at the scene. Children between 0 and 14 years of age died most frequently from traumatic brain injury. In adolescents between 14 and 18 years of age, polytrauma was mostly the cause of death with a high coincidence of suicidal deaths. The frequency of fatal traffic accidents and suicides shows the need to improve accident and suicide prevention for children and adolescents.

Trends in Presentation and Management of Pediatric Renal Trauma

OBJECTIVE

We queried the Pediatric Health Information System (PHIS) to evaluate the presentation, management, and outcomes of renal trauma in children from birth to 18 years from 2007-2018.

METHODS

Patients were categorized as infants (0-1 year), toddlers (2-4 years), children (5-9 years), preteen (10-14 years), and teens (15-18 years), and patient demographics, grade of injury, and mechanism of injury including sports-related trauma (SRT) were collected. Each group was then evaluated for the level of management and patient outcome.

RESULTS

We identified 3720 patients with renal trauma. Our cohort was predominantly White (68.5%), male (68.6%), and required public insurance (38.5%). Most injuries were low grade (86.7%) and managed non-operatively (94.7%). The overall mortality was 51 (1.4%). Younger patients (infants, toddlers, children) were more likely to present with complex injuries and they were more likely to have been involved in a motor vehicle accident. They had higher blood transfusion rates, longer inpatient courses, higher levels of admission acuity, and higher mortality. Patients in the older age groups presented most after SRT. Across all age groups, the most common source of SRT was limited contact sports; however, when considering only teens, full contact sports were the primary offending activity. This review of the PHIS database provides insight to the rates and patterns of pediatric renal trauma in the United States.

CONCLUSION

Our data suggest an age-related differences in the presentation, management, and outcomes of pediatric renal trauma patients.

Trends and characteristics of severe road traffic injuries in children: a nationwide cohort study in Japan

PURPOSE

The purpose of this study was to evaluate temporal trends of characteristics of severe road traffic injuries in children and identify factors associated with mortality using a nationwide database in Japan.

METHODS

We performed a retrospective analysis of Japan Trauma Data Bank (JTDB) from 2004 to 2018. We included patients with traffic injuries under the age of 18 who were hospitalized. The primary outcome was in-hospital mortality. We evaluated trends in characteristics and assessed factors associated with in-hospital mortality using a logistic regression analysis.

RESULTS

A total of 4706 patients were analyzed. The most common mechanism of injury was bicycle crash (34.4%), followed by pedestrian (28.3%), and motorcycle crash (21.3%). The overall in-hospital mortality was 11.2%. We found decreasing trends in motorcycle crash and in-hospital mortality and increasing trends in rear passenger seats in cars over the 15-year period. The following factors were associated with in-hospital mortality: car crash (aOR 1.69, 95%CI 1.18-2.40), pedestrian (aOR 1.50, 95%CI 1.13-1.99), motorcycle crash (aOR 1.42, 95%CI 1.03-1.95) [bicycle crash as a reference]; concomitant injuries to head/neck (aOR 5.06, 95%CI 3.81-6.79), thorax (aOR 2.34, 95%CI 1.92-2.87), abdomen (aOR 1.74, 95%CI 1.29-2.33), pelvis/lower-extremity (aOR 1.57, 95%CI 1.23-2.00), spine (aOR 3.01, 95%CI 2.02-4.43); and 5-year increase in time period (aOR 0.80, 95%CI 0.70-0.91).

CONCLUSIONS

We found decreasing trends in motorcycle crash and in-hospital mortality, increasing trends in rear passenger seats in cars over the 15-year period, and factors associated with in-hospital mortality such as type of mechanisms and concomitant injuries. Strengthening child road safety measures, particularly for rear passenger seats in vehicles, is imperative to enhance our dedication to injury prevention.

Which Trauma Severity Scores Are Useful in Predicting Pediatric Mortality?

BACKGROUND AND OBJECTIVES

Trauma is the leading cause of death in children. Several trauma severity scores exist: the shock index (SI), age-adjusted SI (SIPA), reverse SI (rSI), and rSI multiplied by Glasgow Coma Score (rSIG). However, it is unknown which is the best predictor of clinical outcomes in children. Our goal was to determine the association between trauma severity scores and mortality in pediatric trauma.

DESIGN AND METHODS

A multicenter retrospective study was performed using the 2015 US National Trauma Data Bank, including patients 1 to 18 years old and excluding patients with unknown emergency department dispositions. The scores were calculated using initial emergency department parameters. Descriptive analysis was carried out. Variables were stratified by outcome (hospital mortality). Then, for each trauma score, a multivariate logistic regression was conducted to determine its association with mortality.

RESULTS

A total of 67,098 patients with a mean age of 11 ±5 years were included. Majority of the patients were male (66%) and had an injury severity score <15 (87%). Eighty-four percent of patients were admitted: 15% to the intensive care unit and 17% directly to the operating room. The mortality at hospital discharge was 3%.There was a statistically significant association between SI, rSI, rSIG, and mortality ( P < 0.05). The highest adjusted odds ratio for mortality corresponded to rSIG, followed by rSI then SI (8.51, 1.9, and 1.3, respectively).

CONCLUSION

Several trauma scores may help predict mortality in children with trauma, the best being rSIG. Introduction of these scores in algorithms for pediatric trauma evaluations can impact clinical decision-making.

A Comprehensive Analysis of the Radiation Exposure and the Diagnostic Benefit of PanCT in Pediatric Cases with Multiple Trauma

Background and Objectives: The primary objective of this study was to obtain quantitative data, taking into account the amount of radiation exposure, about the clinical and diagnostic benefit obtained from panCT in pediatric trauma cases. Thus, we aim to create greater awareness in all physicians and primarily emergency medicine physicians regarding correct selection in terms of the patient group where this effective radiological method is to be applied, and to protect children from the adverse effects of radiation. Materials and Methods: The computed tomography (CT) images were retrieved from the hospital radiological archive system (PACS). The effective dose (Ed) was calculated using the standardized method including the tissue weighted parameters. The radiological pathologies determined as a result of CT imaging of the cases were categorized according to clinical significance in accordance with the Modified CT Colonography Reporting and Data System (C-RADS). Results: The data for a total of 268 patients were analyzed, comprising 89 (33.2%) females and 179 (66.8%) males with a mean age of 8.81 ± 5.21 years. The mean Ed was determined to be 18.14 ± 10.44 mSv. The Ed was determined to be statistically significantly higher in the 1-5 years age group than in the 15-18 years age group (p = 0.024). A statistically significant difference was determined between the age groups in terms of the pathologies determined (p = 0.028). Conclusions: In order to prevent performing unnecessary CT imaging, trauma teams in Emergency Departments (ED) should work in harmony and individual decision-making should be based on the severity of the trauma mechanism, the severity of the predicted injury, and the clinical status of the injured child.

Epidemiology and Pattern of Orthopedic Trauma in Children and Adolescents: Implications for Injury Prevention

BACKGROUND

Orthopedic injuries are prevalent in children and can result in hospitalization and damage. The number of accidental injuries among children increases every year, leading to a huge burden on communities and health institutions.

AIM

This study aimed to assess the epidemiological pattern of orthopedic trauma among children and adolescents in Abha, Saudi Arabia.

METHODS

A retrospective record-based study was carried out to investigate the epidemiological pattern of orthopedic trauma among children and adolescents treated at Abha Maternity and Children Hospital in Saudi Arabia, a traumatic center for pediatric patients. The study covered all children and adolescents treated at the hospital for orthopedic trauma. The parents of the children and adolescents were called to get their consent to participate in the study. The following data were extracted from the medical files: personal information, medical history, trauma-related details, management, hospitalization, and complications.

RESULTS

A total of 295 children and adolescents were included. The mean ± standard deviation age was 6.8 ± 3.1 years old (range 1 month to 13 years). Of the patients, 186 (63.1%) were male. The most reported causes of traumas were fall from height (48.1%) and injury while playing (19.7%). The most affected body parts included the forearm (22.4%), head (21.7%), thigh (20%), and leg (10.8%). The vast majority of the children and adolescents (87.1%) had no complications.

CONCLUSION

The current study revealed that pediatric orthopedic injuries are not rare, and there is a higher likelihood of injuries among young male children. Fall from height and play-associated injuries are the most frequent causes.

Road Traffic Accidents, Climbing Frames, or Trampolines: What Harms Children in the 2020s?

Background In the modern Western world, activities and the daily routine of children have changed over time. Detailed analyses of the mechanisms of injuries and current fracture patterns in children are rare. The aim of the study was to elicit and investigate the most dangerous leisure and sporting activities leading to fractures in children today. Materials and methods This is a retrospective study focusing on children that were treated in a level-one trauma center in Germany between 2015 and 2020. All children who were 14 years of age or younger and suffered a traumatic injury treated in our emergency department were included in this study. From the database, mechanisms of injury, type of injury, age, and gender were analyzed. Results The study included 12508 patients, including 7302 males and 5206 females. Among the 10 most common mechanisms of injury were collisions (8.6%), falls (7.7%), injuries while playing (6.1%) or while running or walking (5.9%), soccer (5.9%), bicycle accidents (3.8%), and trampoline falls (3.4%). Road traffic accidents involving passengers or pedestrians caused 3.3% of the injuries but were the most common cause of death. The most common mechanisms of injury causing a fracture were falls, playing soccer, and bicycle accidents. Sorting the mechanisms of injury by the percentage that caused a fracture, the most dangerous activities were falling from heights above 2 meters, skiing and snowboarding, climbing and bouldering, skateboarding, and horseback riding. In the five-year study period, four out of six children died due to road traffic accidents. Conclusion Injured children must be provided with the best quality of care 24/7 in orthopedic trauma departments and have to be kept as a focus in the training of orthopedic trauma surgeons. Road traffic accidents are still the main cause of death in children, but they are overall less common. Falls and sports activities are the most likely to cause a fracture.

Failure-to-rescue and mortality after emergent pediatric trauma laparotomy: How are the children doing?

INTRODUCTION

Emergent trauma laparotomy is associated with mortality rates of up to 40%. There is a paucity of data on the outcomes of emergent trauma laparotomies performed in the pediatric population. The aim of our study was to describe the outcomes, including mortality and FTR, among pediatric trauma patients undergoing emergent laparotomy and identify factors associated with failure-to-rescue (FTR).

METHODS

We performed a one-year (2017) retrospective cohort analysis of the American College of Surgeons Trauma Quality Improvement Program dataset. All pediatric trauma patients (age <18 years) who underwent emergent laparotomy (laparotomy performed within 2 h of admission) were included. Outcome measures were major in-hospital complications, overall mortality, and failure-to-rescue (death after in-hospital major complication). Multivariate regression analysis was performed to identify factors independently associated with failure-to-rescue.

RESULTS

Among 120,553 pediatric trauma patients, 462 underwent emergent laparotomy. Mean age was 14±4 years, 76% of patients were male, 49% were White, and 50% had a penetrating mechanism of injury. Median ISS was 25 [13-36], Abdomen AIS was 3 [2-4], Chest AIS was 2 [1-3], and Head AIS was 2 [0-5]. The median time in ED was 33 [18-69] minutes, and median time to surgery was 49 [33-77] minutes. The most common operative procedures performed were splenectomy (26%), hepatorrhaphy (17%), enterectomy (14%), gastrorrhaphy (14%), and diaphragmatic repair (14%). Only 22% of patients were treated at an ACS Pediatric Level I trauma center. The most common major in-hospital complications were cardiac (9%), followed by infectious (7%) and respiratory (5%). Overall mortality was 21%, and mortality among those presenting with hypotension was 31%. Among those who developed in-hospital major complications, the failure-to-rescue rate was 31%. On multivariate analysis, age younger than 8 years, concomitant severe head injury, and receiving packed red blood cell transfusion within the first 24 h were independently associated with failure-to-rescue.

CONCLUSIONS

Our results show that emergent trauma laparotomies performed in the pediatric population are associated with high morbidity, mortality, and failure-to-rescue rates. Quality improvement programs may use our findings to improve patient outcomes, by increasing focus on avoiding hospital complications, and further refinement of resuscitation protocols.

Systematic Identification of the Optimal Housekeeping Genes for Accurate Transcriptomic and Proteomic Profiling of Tissues following Complex Traumatic Injury

Trauma triggers critical molecular and cellular signaling cascades that drive biological outcomes and recovery. Variations in the gene expression of common endogenous reference housekeeping genes (HKGs) used in data normalization differ between tissue types and pathological states. Systematically, we investigated the gene stability of nine HKGs (Actb, B2m, Gapdh, Hprt1, Pgk1, Rplp0, Rplp2, Tbp, and Tfrc) from tissues prone to remote organ dysfunction (lung, liver, kidney, and muscle) following extremity trauma. Computational algorithms (geNorm, Normfinder, ΔCt, BestKeeper, RefFinder) were applied to estimate the expression stability of each HKG or combinations of them, within and between tissues, under both steady-state and systemic inflammatory conditions. Rplp2 was ranked as the most suitable in the healthy and injured lung, kidney, and skeletal muscle, whereas Rplp2 and either Hprt1 or Pgk1 were the most suitable in the healthy and injured liver, respectively. However, the geometric mean of the three most stable genes was deemed the most stable internal reference control. Actb and Tbp were the least stable in normal tissues, whereas Gapdh and Tbp were the least stable across all tissues post-trauma. Ct values correlated poorly with the translation from mRNA to protein. Our results provide a valuable resource for the accurate normalization of gene expression in trauma-related experiments.

Epidemiology, patterns, and mechanisms of pediatric trauma: a review of 12,508 patients

BACKGROUND

Pediatric traumas are common and remain a unique challenge for trauma surgeons. Demographic data provide a crucial source of information to better understand mechanisms and patterns of injury. The aim of this study was to provide this information to improve treatment strategies of potentially preventable morbidity and mortality in children.

MATERIAL AND METHODS

A retrospective review of every pediatric trauma treated in the emergency department (ED) between 2015 and 2019 was performed. Inclusion criteria were the age between 0 and 14 years and admission to the ED after trauma. Demographic data, time of presentation, mechanism of injury and pattern of injury, treatment, and outcome were analyzed. Different injury patterns were assessed in relation to age group, sex, mechanism of injury and treatment.

RESULTS

A total of 12,508 patients were included in this study. All patients were stratified into five age groups: babies under the age of 1 (8.8%), toddlers between 1 and 3 (16.8%), preschool children between 4 and 6 (19.3%), young school children between 7 and 10 (27.1%), and young adolescents between 11 and 14 (27.9%). The predominant sex in all age groups was male. 47.7% of patients were admitted between 4 and 10 pm; 14.8% of the patients arrived between 10 pm and 8 am. Peak months of admissions were May to July. Overall, 2703 fractures, 2924 lacerations and superficial tissue injury, 5151 bruises, 320 joint dislocations, 1284 distortions, 76 burns, and 50 other injuries were treated. Most common mechanisms for fractures were leisure activities, falls, and sports-related activities. Forearm fractures were the most common fractures (39.5%) followed by humerus fractures (14%) and fractures of the hand (12.5%). A total of 700 patients with fractures (25.9%) needed surgery. 8.8% of all patients were hospitalized for at least one day. 4 patients died in the hospital (0.03%).

CONCLUSION

Despite of higher risk, severe injuries in children are rare. Minor injuries and single fractures are common. Treatment should be managed in specialized centers to ensure an interdisciplinary care and fast recovery. Peak times in the late afternoon and evening and summer months should be taken into consideration of personnel planning.

Epidemiological pattern of trauma patients based on the mechanisms of trauma: trends of a regional trauma center in Midwest of Iran

INTRODUCTION

Trauma is one of the important issues in public health because it is responsible for 90% of mortality in Low and Middle-Income Countries (LIMCs). The present study aimed to determine the epidemiological pattern of trauma patients in a regional trauma center in the Midwest of Iran from 2014 to 2020.

METHODS

This study was a retrospective study that was performed on 29,804 trauma patients admitted to Be'sat Hospital in Hamadan from January 2014 to December 2020. Data was collected using Health Information Management (HIM) Center of the Be'sat Hospital. For investigating the relationship of the characteristics of trauma patients and the mechanisms of trauma, Multiple Multinomial Logistic Regression (MMNLR) model was used. All statistical analyses were performed using the IBM SPSS Statistics version 24.

RESULTS

The mean age of all patients was 35.4 (SD = 21.9) years. Most of them were men (71.7%). The most common mechanism of trauma was road traffic accidents (RTAs) (39.6%) followed by falls (30.2%), other (19.7%), violence (6.2%), and burn (4.4%). 1.5% of the trauma patients expired. The results of multiple multinomial logistic regression indicated that significant affected factor on odds referring because of RTAs compared to other mechanism were: season and hospital length of stay (LOS); in falls and violence: age, sex, season, and LOS; and in burn: age, sex, season, evening time, and LOS (p < 0.05).

CONCLUSION

Based on the investigation of 29,804 trauma patients, in Iran as a developing country, RTAs and falls were two common mechanisms of trauma. It seems that as a short-term plan, it is possible to focus on road safety, to improve the quality of vehicles, to hold training courses for drivers. Also, as a long-term goal, considering that the elderly population in Iran is increasing, it is necessary to pay attention to fall reduction programs.

Contribution of the Technical Efficiency of Public Health Programs to National Trends and Regional Disparities in Unintentional Childhood Injury in Japan

To achieve the Sustainable Development Goals, strengthening investments in health service inputs has been widely emphasized, but less attention has been paid to tackling variation in the technical efficiency of services. In this study, we estimated the technical efficiency of local public health programs for the prevention of unintentional childhood injury and explored its contribution to national trend changes and regional health disparities in Japan. Efficiency scores were estimated based on the Cobb-Douglas and translog production functions using a true fixed effects model in a stochastic frontier analysis to account for unobserved time-invariant heterogeneity across prefectures. Using public data sources, we compiled panel data from 2001 to 2017 for all 47 prefectures in Japan. We treated disability-adjusted life years (DALYs) as the output, coverage rates of public health programs as inputs, and caregivers' capacity and environmental factors as constraints. To investigate the contribution of efficiency to trend changes and disparities in output, we calculated the predicted DALYs with several measures of inefficiency scores (2001 average, yearly average, and prefecture-year-specific estimates). In the translog model, mean efficiency increased from 0.62 in 2001 to 0.85 in 2017. The efficiency gaps among prefectures narrowed until 2007 and then remained constant until 2017. Holding inefficiency score constant, inputs and constraints contributed to improvements in average DALYs and widened regional gaps. Improved efficiency over the years further contributed to improvements in average DALYs. Efficiency improvement in low-output regions and stagnated improvement in high-output regions offset the trend of widening regional health disparities. Similar results were obtained with the Cobb-Douglas model. Our results demonstrated that assessing the inputs, constraints, output, and technical efficiency of public health programs could provide policy leverage relevant to region-specific conditions and performance to achieve health promotion and equity.

Characteristics of School Injuries Presenting to the Emergency Department

Background  School injuries account for approximately one-fifth of pediatric injuries. We aimed to investigate the frequency and severity of school injuries among school-aged children and determine clinical diagnoses and surgery requirement data.

Methods  In this prospective study, children who were admitted to the emergency department due to school accidents over a 5-month period were included. Demographics, activity during trauma, mechanism of trauma, nature, severity, emergency department outcomes, and surgery requirement were evaluated.

Results  The study included a total of 504 school-aged children, of whom 327 (64.9%) were male and 177 (35.1%) were female. Of the children, 426 (84.5%) had no evidence of injury or minor injury, while 78 (15.5%) had moderate or severe injury. There was a statistically significant difference between these two groups in terms of gender ( p  = 0.031). Of the 78 children with moderate or severe injuries, 45 had extremity fractures, 18 had lacerations, 5 had maxillofacial injuries, 4 had cerebral contusion, 1 had lung contusion, and 1 had cervical soft-tissue damage. Two patients with fractures and two with eyelid lacerations were treated surgically, and four patients with brain contusion were hospitalized for a close follow-up.

Conclusion  This study revealed that the most common moderate or severe injuries in school accidents referred to emergency department were distal radius fractures and lacerations.

Mechanisms, Pattern and Outcome of Pediatrics Trauma At Agaro General Hospital, Southwest Ethiopia, 2021

Introduction

Over 80% of trauma related deaths in children occur in low income and middle-income countries including Ethiopia. Trauma affects several aspects of child life and is still a major concern. Despite the Ethiopian federal ministry of health (FMoH) conducting away different trials, there was an increased burden and high projection of pediatric trauma. In Ethiopia, There is insufficient evidence about the mechanisms, patterns and outcomes of pediatric trauma including this study area, Therefore this study aimed to assess the mechanisms, patterns, and outcomes of pediatric trauma in Agaro General Hospital, Southwest Ethiopia, 2021.

Methods and Materials

This cross-sectional study was study conducted on randomly selected 405pediatric patients who visited the Agaro General Hospital between 1/1/2018 and 30/8/2021. Data were extracted from each medical chart using a structured checklist. Data were entered into Epi-data 4.4.2.1for cleaning and analyzed using SPSS version 24. Tables, charts, and text are used to report the results.

Results

A total of 405 patients were included in the study. This study revealed that majority 271 (66.9%) of injured children were males. Most 188 (46.4%) of the traumas were occurred on the street. Fall down injury were the most common 151(37.3%) cause of trauma, followed by road traffic accidents 98 (24.2%). Trauma caused by falls accounted for 43.7% and 34.4% % of all traumas in the 5–12 year and the <5 year age groups respectively. Most 126 (31.1%) of the subjects were exposed to head and face trauma. Majority 256 (63.2%) of children were discharged with improvement, while12 (3.0%) of them have died.

Conclusions

Pediatric trauma remains a major public health concern. Most of trauma occurred among boys and falldown injury was the most frequent trauma, and the majority of the subjects were exposed to head and face trauma. Therefore, children should receive safety precautions, more supervision, and identification of specific risk factors for these injuries, and should be prohibited from risky practices by concerned bodies including families and traffic officers.

Paediatric injury in Beirut: a multicentre retrospective chart review study

OBJECTIVE

This study aims to assess the epidemiology of paediatric injury in Beirut, giving insights into their characteristics, contributing risk factors and outcomes.

DESIGN AND SETTING

A retrospective study was conducted to review medical charts for children aged 0-15 years presented to five hospital emergency departments (ED) located in Beirut over a 1-year period (June 2017-May 2018).

PARTICIPANTS

A total of 1142 trauma-related visits for children under 15 years of age were included. A descriptive analysis and a bivariate analysis were performed to investigate admitted and treated/discharged patients.

PRIMARY OUTCOME

A logistic regression was conducted to identify factors associated with hospital admission among injured children.

RESULTS

A total of 1142 cases of paediatric injury ED cases were sampled, mean age was 7.7±4.35 years. Children aged 0-5 years accounted for more than one-third of the total cases, 40.0% (206/516) of the fall injuries and 60.1% (220/366) of home injuries. The leading cause of paediatric injury was fall (45.2%), nearly 4.1% of the cases were admitted to hospitals. Factors associated with admission included injury to abdomen (OR=8.25 (CI 1.11 to 61.24)), to upper extremity (OR=5.79 (CI 2.04 to 16.49)), to lower extremity (OR=5.55 (95% CI 2.02 to 15.20) and other insurance type (OR=8.33 (CI 2.19 to 31.67)). The three types of injuries mostly associated with hospital admission were fracture (OR=13.55 (CI 4.77 to 38.44)), concussion (OR=13.60 (CI 2.83 to 65.41)) and organ system injury (OR=31.63 (CI 3.45 to 290.11)).

CONCLUSIONS

Injury remains a major health problem among the paediatric population in Lebanon. Parental child safety educational programmes and age-targeted injury prevention strategies should be initiated and implemented to mitigate the burden of child injuries and improve child safety and well-being.

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.

Mortality of hospital walk‐in trauma patients: a multicenter retrospective cohort study

Aim

To investigate the characteristics of patients who visited the emergency department by themselves after experiencing trauma and subsequently died, and to identify the prognostic factors of mortality in such patients.

Methods

Adult patients with trauma visiting the emergency department by themselves between 2004 and 2019 in Japan were identified using a nationwide trauma registry (the Japan Trauma Data Bank). The characteristics of patients who died were compared with those who survived, and multivariable logistic regression analysis was used to determine the independent association of each preselected variable with in‐hospital mortality (end‐point).

Results

Of the 9753 patients eligible for analysis, 4369 (44.8%) were men, and the median age was 75 years. Of these patients, 130 (1.3%) died in the hospital. The following factors had a significant association with in‐hospital mortality: age, male sex, Charlson Comorbidity Index (CCI) 3–4 and ≥5 with CCI = 0 as a reference, circumstances of injury (free fall and fall at ground level), Glasgow Coma Scale score, Shock Index ≥ 0.9, severe injuries of the head, abdomen and lower extremities, and Injury Severity Score ≥ 15.

Conclusions

Several risk factors, including older age, male sex, higher CCI, circumstances of injury (free fall and fall at ground level), lower Glasgow Coma Scale score, higher Shock Index, and severe injuries of the head, abdomen, and lower extremities, were identified as being associated with the death of trauma patients visiting the emergency department by themselves. Early identification of patients with these risk factors and appropriate treatment may reduce mortality posttrauma.

Failure to Rescue in Geriatric Trauma: The Impact of Any Complication Increases with Age and Injury Severity in Elderly Trauma Patients

INTRODUCTION

The interaction of increasing age, Injury Severity Score (ISS), and complications is not well described in geriatric trauma patients. We hypothesized that failure to rescue rate from any complication worsens with age and injury severity.

METHODS

The National Trauma Data Bank (NTDB) was queried for injured patients aged 65 years or older from January 1, 2013 through December 31, 2016. Demographics and injury characteristics were used to compare groups. Mortality rates were calculated across subgroups of age and ISS, and captured with heatmaps. Multivariable logistic regression was performed to identify independent predictors of mortality.

RESULTS

614,496 geriatric trauma patients were included; 151,880 (24.7%) experienced a complication. Those with complications tended to be older, female, non-white, have non-blunt mechanism, higher ISS, and hypotension on arrival. Overall mortality was highest (19%) in the oldest (≥86 years old) and most severely injured (ISS ≥ 25) patients, with constant age increasing across each ISS group was associated with a 157% increase in overall mortality (P < .001, 95% CI: 148-167%). Holding ISS stable, increasing age group was associated with a 48% increase in overall mortality (P < .001, 95% CI: 44-52%). After controlling for standard demographic variables at presentation, the existence of any complication was an independent predictor of overall mortality in geriatric patients (OR: 2.3; 95% CI: 2.2-2.4).

CONCLUSIONS

Any complication was an independent risk factor for mortality, and scaled with increasing age and ISS in geriatric patients. Differences in failure to rescue between populations may reflect critical differences in physiologic vulnerability that could represent targets for interventions.

Pattern and Outcomes of Injuries among Trauma Patients in Gedeo Zone, Dilla, South Ethiopia: A 5 Years Retrospective Analysis

Background

Injury has become a life threatening community health problem associated with significant mortality and morbidity worldwide. The aim of this study was to assess the burden of injury in Dilla University Hospital.

Methods

Institution-based retrospective cross-sectional study was conducted from January 2015 to June 2019. Data was collected using questionnaire adapted from WHO injury surveillance guideline. Bivariate and multivariate logistic regressions were performed to determine the factors associated with hospital mortality.

Results

Road traffic accident was the commonest cause of injury 178(47.3%) followed by interpersonal violence 113(30.1%). Revised trauma score (RTS) < 10 (AOR=2.5; 95% CI, 1.8–25.6), Glasgow coma scale (GCS) (AOR =0.3; 95% CI, 0.13–0.5), length of hospitalization (LOS) 1–7 days (AOR=0.1; 95% CI, 0.01–0.8) and time of arrival >24hr were predictors of mortality in a patient with injury.

Conclusion

Lower extremity injury was common and mostly associated with RTA. Pre-hospital emergency medical service system and trauma registry need to be established to decrease the burden of injury.

Epidemiology of pediatric trauma in the Kingdom of Bahrain: a national pediatric trauma registry pilot study

Background

A pediatric trauma registry for the Kingdom of Bahrain would be a novel public health tool for the Bahraini health system. The aim of this study was to explore the epidemiology of pediatric trauma at the national level by describing the distribution of pediatric injury in the Kingdom, and quantifying the burden of injury shouldered by the study population.

Methods

This multicenter observational cross-sectional study was conducted in Bahrain using data from the Pediatric Trauma Registry (PTR), which was a short-term paper-based prospective trauma registry that collected data over a three-month period in 2018. PTR was based in the pediatric emergency departments (ED) of the three national referral hospitals in the Kingdom. By simultaneously collecting data from all three trauma hospitals in the country, it was assumed that during the data collection period all major pediatric trauma patients in the country would be captured by the study, and that the data collected would provide national estimates of trauma. Inclusion criteria for the study was any individual under the age of 14, that arrived at the ED seeking care for intentional and unintentional injuries.

Results

A total of 1328 patients were included in the study. Sixty-nine percent of patients were treated and discharged from the ED, 30.5% were admitted to the hospital, admitted for surgery, or seen by a specialist, and 0.5% were declared deceased. The percentage of patients documented as unrestrained during Motor Vehicle Collisions (MVC) was 92.3%, and amongst those involved in MVC, 12% were ejected from the cabin of the vehicle.

Conclusions

There are significant implications that this study holds for policy implementation and practice surrounding injury prevention in the Kingdom of Bahrain. Low seatbelt utilization and the high proportion of ejection amongst MVC victims warrant immediate public health policy implementation, including enforcement of seat belt laws, strengthening of the traffic court system, and awareness campaigns for MVC prevention. Additionally, pediatric drowning prevention programs centered on constant adult supervision, pool isolation fencing, personal flotation devices, and swimming education should be created to address the mortality attributable to drowning in this study.

Isolated high-grade splenic injury among pediatric patients in Japan: Nationwide descriptive study

BACKGROUND

Limited information exists regarding the clinical characteristics, management practice, and outcomes of pediatric patients with isolated splenic injury in Japan. This study aimed to evaluate the characteristics, management, and outcomes, such as survival and splenic salvage rate of pediatric patients with isolated splenic injury in Japan.

METHOD

This study was a multicenter retrospective cohort study using patient data from the Japan Trauma Data Bank (JTDB) collected between 2004 and 2018. Pediatric patients with isolated high-grade splenic injury whose abbreviated injury scale≥3 were classified according to management groups: nonoperative management (NOM); NOM with splenic artery embolization (SAE); and operative management (OM). The primary outcome was in-hospital survival and the secondary outcomes were splenic salvage rate, hospital length of stay (LOS), rate of discharging to home, and complications.

RESULTS

There were 230 pediatric patients with isolated high-grade splenic injury during the study period. Of these, 156 (68%) were managed by NOM, 62 (27%) were managed by NOM with SAE, and 12 (5.2%) were managed by OM. No pediatric patient with isolated high-grade splenic injury died between 2004 and 2018 in Japan, and the splenic salvage rate was 97%.

CONCLUSION

We identified a high survival rate and splenic salvage rate among pediatric patients with isolated high-grade splenic injury in Japan. SAE was often used, in contrast with previous reports.

LEVELS OF EVIDENCE

Level IV.

Severe liver trauma among pediatric patients in the Japan Trauma Registry

Background

Limited information exists regarding the clinical characteristics, management practices, and outcomes of pediatric patients with liver injury in Japan. The aim of this study is to evaluate the characteristics, management, and outcome of pediatric patients with liver injury in Japan.

Methods

We conducted a multicenter, retrospective cohort study using data from the Japan Trauma Data Bank between 2004 and 2018. Pediatric patients with liver injury were classified into the following management groups: nonoperative management (NOM); NOM with angioembolization (AE); operative management (OM). The primary outcome was in-hospital survival, and the secondary outcomes were dispositions, hospital length of stay (LOS), and rate of discharge to home.

Results

There were 308 pediatric patients with severe liver injury (organ injury scale grades ≥Ⅲ) during the study period; 135 patients had isolated liver injury and 173 patients had non-isolated liver injury. The rates of NOM, NOM with AE, and OM among all patients were 65%, 23%, and 12%, respectively. AE was highly used both in patients with isolated liver injury (27%) and non-isolated liver injury (22%). In-hospital survival of patients with isolated liver injury and those with non-isolated liver injury were 99% and 88%, respectively. Regarding secondary outcomes among patients with isolated liver injury, 82% were admitted to the intensive care unit. LOS was 11 (8–14) days and 82% were discharged to home.

Conclusions

Our retrospective observational study showed that management of pediatric patients with severe liver injury in Japan was characterized by high utilization of AE. The in-hospital survival rate in Japan was comparable with that of other developed countries.

Using Weather, Lunar Cycles, and Time of Year to Predict Trauma Incidents in an Urban, Level I Pediatric Trauma Center

BACKGROUND

Trauma patterns in adults are influenced by weather conditions, lunar phases, and time of year. The extent to which these factors contribute to pediatric trauma is unclear.

OBJECTIVE

The present study aimed to review patients from a single Level I pediatric trauma center to determine the influence of weather, the lunar cycle, and time of year on trauma activity.

METHODS

A retrospective review of trauma activations (n = 1,932) was conducted from 2015 to 2017. Injury type and general demographics were collected. Weather data and lunar cycles were derived from historical databases.

RESULTS

Days with no precipitation increased the total number of injuries of all types compared with those with precipitation (p < .001). Blunt and penetrating injuries were more likely to occur during full moons, whereas burn injuries were significantly higher during new moons (p < .001). Blunt trauma was significantly higher in September than all other months, F(11, 1,921) = 4.25, p < .001, whereas January had a significantly higher number of burns than all other months (p < .001).

CONCLUSIONS

Pediatric trauma trends associated with external factors such as weather, lunar cycles, and time of year can inform hospital staffing decisions in anticipation of likely injuries and help direct injury prevention efforts.

National Surveillance of Injury in Children and Adolescents in the Republic of Korea: 2011-2017

Understanding age-specific injury patterns allows the continued improvement of prevention strategies. This is a retrospective study analyzing the Korea Emergency Department-Based Injury In-depth Surveillance data, including those aged ≤19 years old between January 2011 and December 2017. In this study, we focused on changes in the modes of injury and severity, and prevention potential by dividing the patients into four age groups: group 1 (0-4 years), group 2 (5-9 years), group 3 (10-14 years), and group 4 (15-19 years). The most common mode of injury in younger age groups 1 and 2 was a fall or slip. Most injuries in older age groups 3 and 4 were unintentional and intentional collisions combined. Traumatic brain injuries (2.1%), intensive care unit admissions (1.8%), and overall death (0.4%) were the highest in group 4. The proportions of severe and critical injury (EMR-ISS ≥ 25) were 7.5% in group 4, 3.2% in group 3, 2.5% in group 1, and 1% in group 2. This study presents a comprehensive trend of injuries in the pediatric population in South Korea. Our results suggest the importance of designing specific injury-prevention strategies for targeted groups, circumstances, and situations.

Characteristics, injuries, and clinical outcomes of geriatric trauma patients in Japan: an analysis of the nationwide trauma registry database

Geriatric trauma is a major socio-economic problem, especially among the aging Japanese society. Geriatric people are more vulnerable to trauma than younger people; thus, their outcomes are often severe. This study evaluates the characteristics of geriatric trauma divided by age in the Japanese population. We evaluated trauma characteristics in patients (n = 131,088) aged ≥ 65 years by segregating them into 2 age-based cohorts: age 65–79 years (65–79 age group; n = 70,707) and age ≥ 80 years (≥ 80 age group; n = 60,381). Clinical characteristics such as patient background, injury mechanism, injury site and severity, treatment, and outcome were examined. Injuries among men were more frequent in the 65–79 age group (58.6%) than in the ≥ 80 age group (36.3%). Falls were the leading cause of trauma among the 65–79 age group (56.7%) and the ≥ 80 age group (78.9%). In-hospital mortality was 7.7% in the 65–79 age group and 6.6% in the ≥ 80 age group. High fall in the ≥ 80 age group showed 30.5% mortality. The overall in-hospital mortality was 11.8% (the 65–79 age group, 12.3%; the ≥ 80 age group, 11.2%). Most hospitalized patients were transferred to another hospital (the 65–79 age group, 52.5%; the ≥ 80 age group, 66.2%). We demonstrated the epidemiological characteristics of Japanese geriatric trauma patients. The overall in-hospital mortality was 11.8%, and fall injury in the ≥ 80 age group required caution of trauma care.

The management and outcome of pediatric blunt chest-abdominal injuries

BACKGROUND

The aim of this study was to determine the frequency and nature of pediatric blunt chest-abdominal injuries (BCAIs) and to summarize their management, ranging from non-operative management (NOM), with or without angioembolization (AE), to surgical treatment.

METHODS

This retrospective study included patients admitted to our hospital for BCAIs from January 1996 to December 2017. The age, injury pattern, organs of injury, outcome, and treatment were summarized.

RESULTS

One hundred and thirty-two patients (98 males, 34 females, mean age 7.68 years ± 3.58, range 1-15 years) were included in the study. Their injuries resulted from motor-vehicle traffic incidents (n = 60), single-bicycle injuries (n = 16), falls (n = 33), sports (n = 10), assault (n = 6), abuse (n = 3), and others (n = 4). There were no injured organs in 31 cases, while there were 130 injured organs in 101 cases, including the liver (n = 42), spleen (n = 35), lung (n = 23), kidney (n = 13), intestine (n = 10), pancreas (n = 5), and adrenal gland (n = 2). Angiography (AG) was performed in 20 cases, and NOM with AE was performed in 16 cases, including 17 organs (liver injury [n = 9], splenic injury [n = 5], and kidney injury [n = 4]). Surgical treatment was performed in eight cases (splenic injury in one, pancreas injury in one, and intestinal injury in six). NOM without AE was performed in the other cases.

CONCLUSIONS

The management of organ injury must take into consideration the management of integrated bleeding. It is recommended that children with severe organ injury are treated in dedicated trauma centers in which AE is available.
