Population-based study of paediatric head injury

Neuropsychological Impairment, Brain Injury Symptoms, and Health-Related Quality of Life After Pediatric TBI in Oslo

Descriptions of clinical outcomes in pediatric traumatic brain injury (pTBI) in Scandinavia are sparse. The Oslo site of the European CENTER-TBI study has performed a pTBI outcome study in a hospitalized population. The main objective was to investigate neuropsychological outcomes, self- and parent-reported symptoms associated with brain injury, and quality of life in children aged 1–15 years, 5–8 months after injury. Fifty-two children were included, and 45 completed the assessments. The sample consisted of 15.4% severe, 21.2% moderate, and 63.4% mild TBI. Subjectively experienced problems with concentration and fatigue were reported by the parents of nearly half of the children. Higher brain injury symptom load was associated with lower quality of life, but was unrelated to injury severity. Group average scores of the sample on neuropsychological testing appeared unimpaired relative to normative means aside from lower performance in working memory. However, based on an impairment index (i.e., 2 or more tests being >1.5 SD below the normative mean), the presence of weak cognitive performance was evident in as many as 45.4% of the sample. Two-thirds of the sample also showed abnormally large intraindividual variability in cognitive functioning (i.e., significant WISC-IV index discrepancies). The findings highlight the need to look beyond group averages on neuropsychological testing. Utilizing an impairment index and considering intraindividual performance variability conveyed deficits that may warrant clinical follow-up. The association of brain injury symptoms with quality of life but not injury severity emphasizes the need to consider symptoms after TBI within a biopsychosocial framework.

Epidemiology of traumatic brain injury in children 15 years and younger in South-Eastern Norway in 2015-16. Implications for prevention and follow-up needs

OBJECTIVE

This retrospective study aimed to describe the volume, severity, and injury mechanism of all hospital-admitted pediatric traumatic brain injury (pTBI) at Oslo University Hospital (OUH), emphasizing consequences for prevention and factors indicating a need for follow-up programs.

METHOD

Data were extracted from the OUH Trauma registry on 176 children, 0-15 years old, admitted to OUH in 2015 and 2016 with a pTBI diagnosis. The dataset contains demographic data, injury mechanism, type, and severity (Glasgow coma scale, GCS; abbreviated injury scale, AIS; injury severity score, ISS), ICD-10 diagnosis codes, level of treatment, and destination of discharge.

RESULTS

79.5% had mild, 9% moderate, and 11.4% severe TBI. The incidence of hospital-treated pTBI in Oslo was 29 per 100,000 per year. The boy: girl ratio was 1.9:1, but in the young teenage group (14-15 years), the ratio was 1:1. Intracranial injury (ICI) identified on CT/MRI was associated with extended hospital stays, with a median of 6 days compared to 1 day for patients without ICI. 27% of the patients assessed as mild TBI at admission had ICI. Children below eight years of age had a higher incidence of moderate and severe ICI from trauma (53% v.s. 28% in children ≥ eight years).

CONCLUSION

The injury characteristics of hospital-treated pTBI are in line with other European countries, but we find the boy-girl ratio different as young teenage girls seem to be catching up with the boys. ICI and length of stay should be considered when deciding which patients need follow-up and rehabilitation.

A Systematic Review of Cognitive Functioning After Traumatic Brain Injury in Individuals Aged 10-30 Years

Given the importance of the period of life from 10 to 30 years in terms of cognitive development and education, combined with the high incidence of traumatic brain injury (TBI) during this period, and limited consensus as to the pattern and degree of cognitive impairment post TBI during this period, we conducted a systematic review to investigate cognitive performance across a range of domains among individuals between the ages of 10 and 30 years who had sustained a TBI. We searched five databases and identified 799 unique records; 52 met our inclusion criteria. These studies reported cognitive function for intelligence, attention, memory, processing speed, and executive function. The majority of the studies reported significant effects, suggesting that TBI is associated with cognitive impairments in these domains. Nine of the studies used physiological tests (EEG and fMRI), the outcomes of which supported behaviorally demonstrated cognitive deficits. In the studies we reviewed, individuals aged 10-30 years who had experienced a TBI performed worse than healthy controls on cognitive function measures-specifically for attention, memory, processing speed, and executive function. In the studies that subjected the individuals with TBI to EEG and fMRI, atypical activation in associated brain regions was demonstrated while the individuals were undergoing cognitive tasks. However, caution should be taken when interpreting the overall results due to the high risk of bias across the majority of the studies. The broader implications of reduced cognitive performance after TBI across this age range are yet to be fully understood.

Traumatic brain injury in children: 18 years of management

Traumatic brain injury in children is a common cause of emergency department admission to our institution. The aim was to summarize the management of all head injuries in children. This was a retrospective, descriptive single center study performed in the Neurosurgery Department, University Hospital Center, Yopougon-Abidjan, Ivory Coast from January 2000 to December 2017. We included all patients less than 16-years-old admitted to the emergency department and all admitted in neurosurgery department for a traumatic brain injury with a cerebral tomodensitometry and/or a magnetic resonance imaging. 292 patients were admitted in neurosurgery department during the study period. The average age of our patients was 7.8 ± 0.80 years with a male predominance (64%). Road accidents were the main causes (78.7%) followed by falls. Brain trauma was mild in 53.8% of cases, moderate in 36.8% and severe in 9.4% of cases. Initial loss of consciousness and headache were the main reasons for admission to the emergency room after the injury with a proportion of 87.6%. The oedemato-haemorrhagic contusion was the most frequent lesion found in our patients with a frequency of 33.9%. The surgery was performed in 36.9% of cases. The overall mortality of patients in the study remains high with a proportion of 13.18%. Traumatic brain injuries in children had a high mortality rate in our practice. Specialized centers should be developed to optimize their care.

Delineating the Nature and Correlates of Social Dysfunction after Childhood Traumatic Brain Injury Using Common Data Elements: Evidence from an International Multi-Cohort Study

Although childhood traumatic brain injury (TBI) has been linked to heightened risk of impaired social skills and behavior, current evidence is weakened by small studies of variable methodological quality. To address these weaknesses, this international multi-cohort study involved synthesis of data from two large observational cohort studies of complicated mild-severe child TBI in Australia and North America. Both studies adopted a unified approach to data collection and coding procedures, providing the opportunity to merge datasets from multiple, well-characterized cohorts for which gold standard measures of social outcomes were collected during the chronic recovery phase. The study involved 218 children, including 33 children with severe TBI, 83 children with complicated mild-moderate TBI, 59 children with orthopedic injury, and 43 age- and sex-matched typically developing control children. All injured children were recruited from academic children's hospitals and underwent direct cognitive assessments including measures of theory of mind (ToM) at least 1-year post- injury. Parents rated their child's social adjustment using standardized measures of social skills, communication and behavior. Results showed a brain-injury specific effect on ToM abilities, such that children with both complicated mild to moderate and severe TBI displayed significantly poorer ToM than children without TBI. In mediator models, poorer ToM predicted poorer parent-rated self-direction and social skills, as well as more frequent behavioral symptoms. The ToM mediated the effect of severe TBI on parent ratings of communication and social skills, as well as on overall behavior symptoms. The findings suggest that deficits in ToM are evident across the spectrum of TBI severity and represent one mechanism linking severe child TBI to long-term social adjustment difficulties. The findings underscore the value of large-scale data harmonization projects to increase the quality of evidence regarding the outcomes of TBI. Clinical and scientific implications are discussed.

Epidemiological and Clinico-radiological Evaluation of Head Injury in Pediatric Population

BACKGROUND

Head injury in infancy and childhood has been documented as the single most common cause of death. In India, children aged <15 years constitute 35% of the total population and contribute to 20-30% of all head injuries. In this study, we attempted to analyze the epidemiological factors, management, and outcome of traumatic brain injury (TBI). The objective of this study were to find the causes of head injury in children and its pattern of distribution in this population and to analyze the efforts required to prevent the injury and management focusing on limiting the progression of primary brain injury and minimizing secondary brain insult.

RESULTS

A total of 2714 patients with head injury were admitted at our hospital during the study period and, out of them, 508 (18.17%) were pediatric patients with age less than 18 years. Of the 508 patients, only 497 patients were included in this study. In the present study, 357 (71.83%) were males and 140 (28.16%) were females. In total, 351 cases were managed conservatively whereas surgical intervention was conducted in 146 cases (P < 0.001). In this study, the most common mode of injury was a road traffic accident (RTA) (46.88%; n=233), followed by fall from height (34.8%; n=173) (P < 0.001). It was also seen that epidural hematoma and fracture hematoma were the most common computed tomography findings in pediatric patients with head injury followed by parenchymal contusion or contusion with or without fracture followed by diffuse axonal injury. A total of 344 cases out of 497 cases were discharged with Glasgow outcome score (GOS)-5 whereas nine cases remained in a persistent vegetative state (GOS-2).

CONCLUSION

Early intervention aimed at the primary lesion in TBI in children generally carries a good outcome, and limits as much as possible the ongoing biomechanical, physiological, and pathological sequelae post-TBI. In teenagers, the importance of proper self-care along with adequate safety gears while doing any TBI-prone activity should be emphasized.

The identification of key factors predictive of traumatic brain injury in paediatric patients with a minor blunt head injury

Introduction:

Traumatic brain injury (TBI) is a major public health concern, and contributes significantly to mortality and morbidity in paediatric patients.

Objective:

The study is aimed to identify the factors predictive of TBI in paediatric patients with a minor blunt head injury.

Methods:

This was a retrospective cohort study conducted on 274 paediatric patients with a minor head injury and registered to Hospital Universiti Sains Malaysia (USM) from the year 2009 to 2013. Patients with a minor blunt head injury aged less than 18 years who underwent computed tomography (CT) of the brain were included, while the patients with penetrating head injuries were excluded from the study. Simple and multiple logistic regression analysis were performed.

Results:

TBI occurred in 49% of the patients. Headache (adjusted odd ratio (AOR): 2.24; 95% confidence interval (CI): 1.24, 4.05, p = 0.008), dizziness (AOR: 3.08, 95% CI: 1.27, 7.51, p = 0.013) and the presence of scalp haematoma (AOR: 2.93, 95% CI: 1.60, 5.34, p < 0.001) were the most important clinical variables for predicting TBI following a minor blunt head injury in paediatric populations.

Conclusion:

Headache, dizziness and scalp haematoma were identified as important clinical variables that can be used to predict TBI on a CT scan of paediatric minor head injury. The presence of these factors should alert emergency physicians to the need to monitor such children closely.

The Impact of Vocational Interventions on Vocational Outcomes, Quality of Life, and Community Integration in Adults with Childhood Onset Disabilities: A Systematic Review

Purpose Despite the desire and ability to work, individuals with childhood onset disabilities are under-represented in employment. Vocational interventions alleviate some barriers to obtaining and maintaining employment for this population. The research question addressed is: What is the impact of vocational interventions on vocational outcomes, quality of life (QoL), and community integration (CI) in adults with childhood onset neurological disabilities including cerebral palsy (CP), spina bifida, and acquired brain injury (ABI)? Methods A literature search was conducted in multiple electronic databases. All experimental and observational studies with comparator group(s) were included. Two reviewers independently completed titles and abstracts screening, full text screening, data abstraction, and risk of bias assessment. Results Seventeen studies were eligible for final inclusion including three randomized-controlled trials, four non-randomized studies, and ten observational studies. Sixteen of seventeen studies included only individuals with ABI, while one study included individuals with CP. Vocational interventions from experimental studies were mainly components of multi-faceted interventions. Most observational studies were from the United States Vocational Rehabilitation Service. Conclusions Vocational interventions may be effective in improving vocational outcomes, QoL, and CI for individuals with ABI. There is limited experimental evidence on interventions that specifically target employment. Observational data suggest that receiving job placement assistance, on-the-job training and supports, counselling/guidance, maintenance, and supported employment successfully predicted employment outcomes.

Association of clinically important traumatic brain injury and Glasgow Coma Scale scores in children with head injury

Objective

Head injury (HI) is a common presentation to emergency departments (EDs). The risk of clinically important traumatic brain injury (ciTBI) is low. We describe the relationship between Glasgow Coma Scale (GCS) scores at presentation and risk of ciTBI.

Methods

Planned secondary analysis of a prospective observational study of children<18 years who presented with HIs of any severity at 10 Australian/New Zealand centres. We reviewed all cases of ciTBI, with ORs (Odds Ratio) and their 95% CIs (Confidence Interval) calculated for risk of ciTBI based on GCS score. We used receiver operating characteristic (ROC) curves to determine the ability of total GCS score to discriminate ciTBI, mortality and need for neurosurgery.

Results

Of 20 137 evaluable patients with HI, 280 (1.3%) sustained a ciTBI. 82 (29.3%) patients underwent neurosurgery and 13 (4.6%) died. The odds of ciTBI increased steadily with falling GCS. Compared with GCS 15, odds of ciTBI was 17.5 (95% CI 12.4 to 24.6) times higher for GCS 14, and 484.5 (95% CI 289.8 to 809.7) times higher for GCS 3. The area under the ROC curve for the association between GCS and ciTBI was 0.79 (95% CI 0.77 to 0.82), for GCS and mortality 0.91 (95% CI 0.82 to 0.99) and for GCS and neurosurgery 0.88 (95% CI 0.83 to 0.92).

Conclusions

Outside clinical decision rules, decreasing levels of GCS are an important indicator for increasing risk of ciTBI, neurosurgery and death. The level of GCS should drive clinician decision-making in terms of urgency of neurosurgical consultation and possible transfer to a higher level of care.

Clinical Parameters, Management, and Outcomes of Childhood Traumatic Brain Injury in Ilorin

Background:

Traumatic brain injury (TBI) is common among children, accounting for 75% of children hospitalized for trauma. Childhood TBI is a leading cause of death from trauma in the pediatric age group and the incidence is on the rise globally.

Objective:

The objective of this study was to determine the etiology, management, and outcome of childhood TBI in our setting.

Subjects and Methods:

This is a retrospective study of all cases of childhood TBI. Relevant data extracted from case records were analyzed using a 2011 Statistical Package for the Social Sciences (SPSS; IBM, Armonk, New York) software for Windows, version 20.

Results:

A total of 168 children with TBI were studied. Of which, 109 (65%) were males and 59 (35%) were females (male/female ratio of 13:7, mean age, 7 ± 4 years). Most of the injuries (138, 82%) occurred outdoor; road traffic crash and fall accounted for 101 (60.1%) and 47 (27.9%) cases, respectively. Pedestrian motor vehicular accident accounted for 41 (41.8%) cases, whereas 30 (30.6%) were due to motorcycle road traffic crash. Good recovery was recorded in 138 (81%) patients, 22 (13.1%) had moderate disability. Mortality rate was 6%.

Conclusion:

Brain injury from trauma still constitutes a significant part of childhood morbidity and mortality in our setting; these deaths are avoidable in most cases. The outlook can be better if preventive efforts are geared toward domestic and road safety campaign.

Estimating the global incidence of traumatic brain injury

OBJECTIVE

Traumatic brain injury (TBI)-the "silent epidemic"-contributes to worldwide death and disability more than any other traumatic insult. Yet, TBI incidence and distribution across regions and socioeconomic divides remain unknown. In an effort to promote advocacy, understanding, and targeted intervention, the authors sought to quantify the case burden of TBI across World Health Organization (WHO) regions and World Bank (WB) income groups.

METHODS

Open-source epidemiological data on road traffic injuries (RTIs) were used to model the incidence of TBI using literature-derived ratios. First, a systematic review on the proportion of RTIs resulting in TBI was conducted, and a meta-analysis of study-derived proportions was performed. Next, a separate systematic review identified primary source studies describing mechanisms of injury contributing to TBI, and an additional meta-analysis yielded a proportion of TBI that is secondary to the mechanism of RTI. Then, the incidence of RTI as published by the Global Burden of Disease Study 2015 was applied to these two ratios to generate the incidence and estimated case volume of TBI for each WHO region and WB income group.

RESULTS

Relevant articles and registries were identified via systematic review; study quality was higher in the high-income countries (HICs) than in the low- and middle-income countries (LMICs). Sixty-nine million (95% CI 64-74 million) individuals worldwide are estimated to sustain a TBI each year. The proportion of TBIs resulting from road traffic collisions was greatest in Africa and Southeast Asia (both 56%) and lowest in North America (25%). The incidence of RTI was similar in Southeast Asia (1.5% of the population per year) and Europe (1.2%). The overall incidence of TBI per 100,000 people was greatest in North America (1299 cases, 95% CI 650-1947) and Europe (1012 cases, 95% CI 911-1113) and least in Africa (801 cases, 95% CI 732-871) and the Eastern Mediterranean (897 cases, 95% CI 771-1023). The LMICs experience nearly 3 times more cases of TBI proportionally than HICs.

CONCLUSIONS

Sixty-nine million (95% CI 64-74 million) individuals are estimated to suffer TBI from all causes each year, with the Southeast Asian and Western Pacific regions experiencing the greatest overall burden of disease. Head injury following road traffic collision is more common in LMICs, and the proportion of TBIs secondary to road traffic collision is likewise greatest in these countries. Meanwhile, the estimated incidence of TBI is highest in regions with higher-quality data, specifically in North America and Europe.

Vocabulary skills of school-age children with acquired brain injury: an exploration of tiered word knowledge and naming errors

BACKGROUND

Vocabulary deficits are the most frequently documented communication difficulty following childhood acquired brain injury (ABI). Given the adverse consequences of limited vocabulary on academic success, it is critical to identify the presence and nature of vocabulary impairments to provide effective intervention for children with ABI.

METHOD

Eleven children (7;6-11;11) with moderate/severe ABI (>12 months post-injury) and individually matched typically developing (TD) controls completed an Australian adaptation of a vocabulary assessment based on a three-tiered framework: tier 1 (basic words), tier 2 (high-frequency, cross-curricular words), and tier 3 (curriculum-based words). Overall scores and tiered accuracy were compared at individual and group level. Type and frequency of expressive naming errors were also coded.

RESULTS

In this pilot study, children with ABI demonstrated poorer overall scores than TD children. Equivalent accuracy was noted for tier 1 words and tier 2 receptive words. However, significantly poorer accuracy was noted in the ABI group for tier 2 expressive words and all tier 3 words. The majority of naming errors were semantic across both groups although TD participants showed a wider distribution of error types.

CONCLUSIONS

Findings support the use of tier 2 and 3 vocabulary as intervention targets in this population within education contexts and speech pathology settings.

The epidemiology of childhood brain injury in the state of Selangor and Federal Territory of Kuala Lumpur, Malaysia

Background

There are limited studies describing the epidemiology of childhood brain injury, especially in developing countries. This study analyses data from the Malaysian National Trauma Database (NTrD) registry to estimate the incidence of childhood brain injury among various demographic groups within the state of Selangor and Federal Territory of Kuala Lumpur.

Methods

This study analysed all traumatic brain injury cases for children ages 0–19 included in the 2010 NTrD report.

Results

A total of 5,836 paediatric patients were admitted to emergency departments (ED) of reporting hospitals for trauma. Of these, 742 patients (12.7 %) suffered from brain injuries. Among those with brain injuries, the mortality rate was 11.9 and 71.2 % were aged between 15 and 19. Traffic accidents were the most common mode of injury (95.4 %). Out of the total for traffic accidents, 80.2 % of brain injuries were incurred in motorcycle accidents. Severity of injury was higher among males and patients who were transferred or referred to the reporting centres from other clinics. Glasgow Coma Scale (GCS) total score and type of admission were found to be statistically significant, χ² (5, N = 178) = 66.53, p < 0.001, in predicting patient outcomes. According to this analysis, the overall rate of childhood brain injury for this one year period was 32 per 100,000 children while the incidence of significant (moderate to severe) brain injury was approximately 8 per 100,000 children.

Conclusions

This study provides an overview of traumatic brain injury rates among children within the most populous region of Malaysia. Most brain injuries occurred among older male children, with traffic, specifically motorcycle-related, accidents being the main mode of injury. These findings point to risk factors that could be targeted for future injury prevention programs.

Parent-Reported Health-Related Quality of Life in Children With Traumatic Brain Injury: A Prospective Study

OBJECTIVE

To identify which specific aspects of health-related quality of life (HRQL) are affected by traumatic brain injury (TBI) injury severity (Severity), time since injury (Time), and the interaction between Severity and Time, in a pediatric sample. It was hypothesized that Severity would decrease HRQL, Time would increase HRQL, and time to recover would be protracted for children with severe TBI.

METHODS

This study followed a pediatric sample (n = 182, aged 6-14 years, recruited through three Australian hospitals) who sustained a mild or moderate-severe TBI across 3, 6, 12, and 18 months post-TBI. 12 specific HRQL outcomes were assessed via the Child Health Questionnaire-Parent Form 50 questionnaire.

RESULTS

Dimensions of HRQL were differentially affected. Children with moderate-severe TBI generally experienced greater initial dysfunction than children with mild TBI; however, this difference disappeared by 18 months post-TBI.

CONCLUSIONS

Specific time points where HRQL outcomes may remediate are identified, and clinical recommendations regarding intervention strategies are discussed.

Role of routine repeat head imaging in paediatric traumatic brain injury

BACKGROUND

Paediatric traumatic brain injuries (TBI) remain a leading cause of morbidity and mortality in Australia. There are clear guidelines on head imaging for children with TBI, but there is conflicting evidence on the role of routine repeat head computed tomography (CT) scan. This study aims to determine whether routine repeat head CT scans in paediatric TBI alter surgical or medical management.

METHODS

A retrospective study was performed at a level 1 tertiary paediatric trauma centre between January 2002 and July 2012. Patients with TBI who were admitted with acute intracranial injury and at least one repeat head CT scan were included. Mechanism of injury, severity of TBI, Glasgow Coma Score, use of intracranial pressure monitoring and operative procedures were listed. The need for operative management was compared for routine and clinically indicated head scans.

RESULTS

Routine head CT scan was done in 36 out of 71 patients (51%). None from this group required craniotomy, but two children (6%) needed delayed ICP monitoring. Three patients with moderate to severe TBI required intracranial pressure monitor or external ventricular drain insertion based on a clinically indicated repeat head CT.

CONCLUSION

Repeat head imaging is more likely to alter management of children with moderate to severe TBI. There is no role for routine repeat CT scan on mild TBI. Results of repeat cranial imaging should be correlated with the clinical status of the patient.

A 2-year prospective surveillance of pediatric traumatic optic neuropathy in the United Kingdom

BACKGROUND

To report epidemiologic data on traumatic optic neuropathy (TON) in patients less than 18 years of age in the United Kingdom acquired by prospective population-based active surveillance through the British Ophthalmic Surveillance Unit.

METHODS

Data were obtained from incident and 6-month follow-up questionnaires sent to reporting ophthalmologists over a period of 2 years. Main outcome measures were demographic data, clinical and visual function at presentation and follow-up, investigations, and treatments used.

RESULTS

A total of 26 cases (21 males) were identified; follow-up data were available for 23 (88%). Minimum estimated annual incidence was 0.99 cases per million. Leading causes of TON included 6 sports injuries (23%), 5 falls (19%), and 4 traffic accidents (16%). Presenting best-corrected visual acuity was ≤ 6/60 in 15 cases (58%), with no light perception in 7 cases (27%). Associated injuries were as follows: nonpenetrating injuries, 8 (31%); adnexal injuries, 3 (11.5%); orbital fractures, 5 (19%); skull fractures, 3 (12%); intracranial bleeding, 1 (4%). Fourteen (54%) received no treatment, and 9 (35%) were treated with steroids. Final visual acuity improved in 7 of 21 patients (33%), with 13 of 23 (56%) achieving final visual acuity ≤ 6/60, 10 of whom (43%) had no light perception. Baseline visual acuity was associated with last follow-up visual acuity (P = 0.03), but treatment and improvement of visual acuity by at least 3 lines were not associated. Treatment was more common in children with poor presenting vision (P = 0.03).

CONCLUSIONS

The incidence, natural history, poor presenting visual acuity, and male prevalence of TON in children appear similar to adults in adults in the UK.

Trauma Incidents Attended by Emergency Medical Services in Victoria, Australia

Introduction:

International literature describing the profile of trauma patients attended by a statewide emergency medical services (EMS) system is lacking. Most literature is limited to descriptions of trauma responses for a single emergency medical service, or to patients transported to a specific Level-1 trauma hospital. There is no Victorian or Australian literature describing the type of trauma patients transported by a state emergency medical service.

Purpose:

The purpose of this study was to define a profile of all trauma incidents attended by statewide EMS.

Methods:

A retrospective cohort study of all patient care records (PCR) for trauma responses attended by Victorian Ambulance Services for 2002 was conducted. Criteria for trauma categories were defined previously, and data were extracted from the PCRs and entered into a secure data repository for descriptive analysis to determine the trauma profile. Ethics committee approval was obtained.

Results:

There were 53,039 trauma incidents attended by emergency ambulances during the 12-month period. Of these, 1,566 patients were in physiological distress, 11,086 had a significant pattern of injury, and a further 8,931 had an identifiable mechanism of injury. The profile includes minor trauma (n = 9,342), standing falls (n = 20,511), no patient transported (n = 3,687), and deceased patients (n = 459).

Conclusions:

This is a unique analysis of prehospital trauma. It provides a baseline dataset that may be utilized in future studies of prehospital trauma care. Additionally, this dataset identifies a ten-fold difference in major trauma between the prehospital and the hospital assessments.

Adaptive ability, behavior and quality of life pre and posttraumatic brain injury in childhood

CONTEXT

Traumatic brain injury (TBI) is a common, acquired childhood disability, which has been shown to have a significant impact on children's cognitive and educational function. While behavioral problems are also noted, there is ongoing debate about the contribution of preinjury factors in this domain. Few studies have attempted to measure the impact of these preinjury functions on postinjury behavior.

OBJECTIVE

To compare pre and postinjury adaptive ability, behavior, executive function and quality of life (QOL) and to identify factors that contribute to outcomes in these domains including injury severity, socio-demographic and preinjury characteristics.

DESIGN

Consecutive recruitments to a prospective, longitudinal study, utilizing a between factor design, with injury severity as the independent variable.

PARTICIPANTS AND METHODS

Children admitted to hospital with a diagnosis of TBI aged between 6 and 14 years (n = 205) were divided according to injury severity (mild, moderate and severe). Adaptive behavior (Vineland Adaptive Behavior Scales), child behavior (Child Behavior Checklist), everyday executive functions (Behavior Rating Inventory of Executive Function) and QOL (Child Health Questionnaire) assessed at 6 months post-TBI.

RESULTS AND CONCLUSIONS

Severity by time interactions were identified across a range of outcome domains demonstrating that more severe injury is associated with a decrease in functional ability at 6 months post-TBI. This effect was most pronounced for everyday executive skills, social function and internalizing aspects of child behavior. Preinjury function was a consistent predictor of postinjury status. Injury severity contributed little to the prediction of functional outcomes once preinjury functioning was accounted for in the model. Age at injury and family cohesion were relevant to specific outcome domains only. Socio-economic status did not contribute significantly to outcome at 6 months. Preinjury functioning as reported by parents in the acute phase may be a useful predictive tool for identifying children who may be at risk of functioning difficulties 6 months post-TBI.

10 years outcome from childhood traumatic brain injury

Childhood traumatic brain injury (TBI) is a common, acquired disability, which has significant implications for subsequent development, and for later quality of life. To date few studies have documented outcomes in these children into adolescence, when academic, social and personal demands increase. The objective of this study was to document functional outcomes at 10 years post-injury, and to identify predictors of outcome including injury, socio-demographic and pre-injury characteristics. The study employed consecutive recruitment to a prospective, longitudinal study. Children with a diagnosis of TBI between 2 and 12 years were initially recruited and divided according to injury severity (mild, moderate, severe). The sample was reviewed at 10 years post-injury and intellectual, adaptive, executive and social domains were investigated. Results indicated that, at 10 years post child TBI, survivors' functional abilities fell overall within the low average to average range regardless of injury severity, suggesting no extreme impairments at a group level for any of the domains under investigation. Significant group differences were identified, though, for adaptive abilities and for speed of processing, with more severe injury associated with poorer performances in each instance. Further, a similar trend was identified for measures of intellectual ability and executive functions. Individual rates of impairment were considerably higher than population expectations across all severity groups for these domains. Although rates of social impairment were also elevated, they were less related to injury factors, suggesting that cognitive/adaptive outcomes and social consequences of TBI may have different bases.

The epidemiology of paediatric head injuries: data from a referral centre in Victoria, Australia

AIM

Currently, there are no population-based or hospital-based studies on the full spectrum of paediatric head injuries (HIs) in Australia. We set out to provide detailed information on the incidence rates, causes and clinical management of all severities of HI in children and adolescents at an Australian tertiary referral centre using emergency department (ED) and admission data as a basis for further investigations and prevention efforts.

METHODS

A retrospective chart review of all children aged 0-16 years who attended the Royal Childrens Hospital (RCH), Melbourne, following a HI in 2004 was used. The cases were identified using the International classification of diseases 10th revision codes, and all medical records were reviewed based on a piloted data form. Information was collected on demographics, injury factors and clinical management of HIs in the hospital setting.

RESULTS

Over the 12-month period, there were 1115 children with an HI who attended the RCH ED, or were admitted. Ninety per cent were classified as mild, 8% as moderate and 3% as severe. Males and children under 3 years had the higher attendance rates. Falls, sports and motor vehicle accidents were the main HI causes. The main sport played (30%) when sustaining an HI was Australian rules football. Thirty-two per cent of children were admitted, 67% of these with mild HI. Twenty-one per cent had a radiology imaging study, most (67%) with a normal result.

CONCLUSIONS

Many HI causes appear preventable, in particular, falls from heights in infants and sports safety. High rates of admission and radiology imaging of mild HI warrant further investigation.

Prevalence and etiology of intracranial hemorrhage in term children under the age of two years: a retrospective study of computerized tomographic imaging and clinical outcome in 798 children

RATIONALE AND OBJECTIVES

The purposes of this study were to retrospectively identify various etiologies underlying intracranial hemorrhages (ICHs) in term infants aged <2 years and their respective prevalence in this population and to describe the long-term clinical outcomes in these patients.

MATERIALS AND METHODS

A retrospective review of the medical records and computed tomographic studies of the head in 798 term infants aged 0 to 24 months with suspected or known ICHs was conducted.

RESULTS

ICHs were present in 195 of the 798 infants (24%). More than one type of ICH was present in 32%. Subdural hemorrhage was the most frequent type of ICH, occurring in 63% of the infants. Good clinical outcomes were present in 49% of the infants but varied depending on the location, etiology, and timing of the ICH.

CONCLUSION

The incidence of various etiologies of ICH depended on the ages of the infants. The overall clinical outcomes were good, with no long-term sequelae in half of the infants presenting with ICHs. In infants aged >4 weeks presenting with ICHs, special attention should be given to the possibility of nonaccidental trauma etiology, because this is common and has worse long-term outcomes.
