Paediatric low speed vehicle run-over fatalities in Queensland

Factors involved in the assessment of paediatric traffic injuries and deaths

Motor-vehicle collisions are the leading cause of unintentional injury and death in children in many parts of the world, including Europe, North America and Australia. The number of fatal collisions has decreased considerably in countries where safety measures such as child restraints, seat belts and air bags have been introduced, providing protection for children within vehicles, although it is recognised that there have been concomitant improvements in emergency responses and techniques, and in hospital treatments. Helmets and changes in external vehicle designs have been implemented to protect paediatric pedestrians and cyclists. However, despite the development of safety guidelines and technologies, injuries still occur. This paper provides an overview of the role of motor-vehicle collisions in paediatric morbidity and mortality to analyse the nature and aetiology of common fatal and non-fatal injuries in children that may present for forensic assessment as passengers, pedestrians or cyclists.

Development, Implementation and Evaluation of an Educational Intervention to Prevent Low Speed Vehicle Run-Over Events: Lessons Learned

There is a growing body of literature regarding low speed vehicle runover (LSVRO) events among children. To date, no literature exists on evaluation of interventions to address this serious childhood injury. Knowledge, attitudes, and behaviour regarding LSVROs were assessed via survey at a shopping centre (pre-intervention), then five months later (post-intervention), to investigate the effect of a population level educational intervention in Queensland, Australia. Participants’ knowledge regarding frequency of LSVRO events was poor. No participant demonstrated ‘adequate behaviour’ in relation to four safe driveway behaviours pre-intervention; this increased at post-intervention (p < 0.05). Most of the sample perceived other’s driveway behaviour as inadequate, and this reduced significantly (<0.05). Perceived effectiveness of LSVRO prevention strategies increased from pre- to post-intervention, but not significantly. TV was the greatest source of knowledge regarding LSVROs pre- and post-intervention. This study provides some evidence that the educational campaign and opportunistic media engagement were successful in increasing awareness and improving behaviour regarding LSVROs. While there are several limitations to this study, our experience reflects the ‘real-world’ challenges associated with implementing prevention strategies. We suggest a multi-faceted approach involving media (including social media), legislative changes, subsidies (for reversing cameras), and education to prevent LSVROs.

Patterns of child death in England and Wales

In the past century, child mortality has fallen to very low rates in all developed countries. However, rates between and within countries vary widely, and factors can be identified that could be modified to reduce the risk of future deaths. An understanding of the nature and patterns of child death and of the factors contributing to child deaths is essential to drive preventive initiatives. We discuss the epidemiology of child deaths in England and Wales. We use available data, particularly that of death registration and other available datasets, and published literature to emphasise issues relevant to reduction of child deaths in developed countries. We examine the different patterns of mortality at different ages in five broad categories of death: perinatal causes, congenital abnormalities, acquired natural causes, external causes, and unexplained deaths. For each category, we explore what is known about the main causes of death and some of the contributory factors. We then explain how this knowledge might be used to help to drive prevention initiatives.

Incidence of paediatric fatal and non-fatal low speed vehicle run over events in Queensland, Australia: eleven year analysis

BACKGROUND

The purpose of this study was to estimate the incidence of fatal and non-fatal Low Speed Vehicle Run Over (LSVRO) events among children aged 0-15 years in Queensland, Australia, at a population level.

METHODS

Fatal and non-fatal LSVRO events that occurred in children resident in Queensland over eleven calendar years (1999-2009) were identified using ICD codes, text description, word searches and medical notes clarification, obtained from five health related data bases across the continuum of care (pre-hospital to fatality). Data were manually linked. Population data provided by the Australian Bureau of Statistics were used to calculate crude incidence rates for fatal and non-fatal LSVRO events.

RESULTS

There were 1611 LSVROs between 1999-2009 (IR=16.87/100,000/annum). Incidence of non-fatal events (IR=16.60/100,000/annum) was 61.5 times higher than fatal events (IR=0.27/100,000/annum). LSVRO events were more common in boys (IR=20.97/100,000/annum) than girls (IR=12.55/100,000/annum), and among younger children aged 0-4 years (IR=21.45/100000/annum; 39% or all events) than older children (5-9 years: IR=16.47/100,000/annum; 10-15 years IR=13.59/100,000/annum). A total of 896 (56.8%) children were admitted to hospital for 24 hours of more following an LSVRO event (IR=9.38/100,000/annum). Total LSVROs increased from 1999 (IR=14.79/100,000) to 2009 (IR=18.56/100,000), but not significantly. Over the 11 year period, there was a slight (non -significant) increase in fatalities (IR=0.37-0.42/100,000/annum); a significant decrease in admissions (IR=12.39-5.36/100,000/annum), and significant increase in non-admissions (IR=2.02-12.77/100,000/annum). Trends over time differed by age, gender and severity.

CONCLUSION

This is the most comprehensive, population-based epidemiological study on fatal and non-fatal LSVRO events to date. Results from this study indicate that LSVROs incur a substantial burden. Further research is required on the characteristics and risk factors associated with these events, in order to adequately inform injury prevention. Strategies are urgently required in order to prevent these events, especially among young children aged 0-4 years.

Risk factors associated with injury and mortality from paediatric low speed vehicle incidents: a systematic review

Objective. This study reviews modifiable risk factors associated with fatal and nonfatal injury from low-speed vehicle runover (LSVRO) incidents involving children aged 0–15 years. Data Sources. Electronic searches for child pedestrian and driveway injuries from the peer-reviewed literature and transport-related websites from 1955 to 2012. Study Selection. 41 studies met the study inclusion criteria. Data Extraction. A systematic narrative summary was conducted that included study design, methodology, risk factors, and other study variables. Results. The most commonly reported risk factors for LSVRO incidents included age under 5 years, male gender, and reversing vehicles. The majority of reported incidents involved residential driveways, but several studies identified other traffic and nontraffic locations. Low socioeconomic status and rental accommodation were also associated with LSVRO injury. Vehicles were most commonly driven by a family member, predominantly a parent. Conclusion. There are a number of modifiable vehicular, environmental, and behavioural factors associated with LSVRO injuries in young children that have been identified in the literature to date. Strategies relating to vehicle design (devices for increased rearward visibility and crash avoidance systems), housing design (physical separation of driveway and play areas), and behaviour (driver behaviour, supervision of young children) are discussed.

Low-speed vehicle run over fatalities in Australian children aged 0-5 years

AIM

The study aims to investigate environmental, socio-demographic and other antecedent risk factors associated with low-speed vehicle run over (LSVRO) mortality in Australian children aged 0-5 years.

METHODS

This is a population-based retrospective case series study of Australian LSVRO mortality, July 2000-December 2010.

MAIN OUTCOME MEASURES

Mortality and corresponding population data were stratified by sex and period to examine trends in incidence rates over the study period. Proportional mortality was also investigated by sex, age, period, area, location of injury, mechanism and other antecedent factors identified from textual coronial information.

RESULTS

There were 82 fatal LSVRO cases over the 11-year study period. The annual incidence was low (less than 1 per 100,000) and declined over the study period. More than three-quarters of incidents occurred in non-traffic settings, in particular residential driveways. The most common vehicle involved was a four-wheel drive or utility with vehicles most likely to be reversing or leaving at the time of the incident. More than three-quarters of cases were aged 36 months or less. A higher proportion of LSVRO fatalities occurred in lower socio-economic status areas compared with higher socio-economic status areas. Where the vehicle was actively being driven (77 cases), the driver was known to the child in three-quarters of cases, most commonly the father (32%).

CONCLUSION

The study provides a detailed analysis of mortality due to LSVRO incidents in Australia and highlights a number of modifiable antecedent factors. Precedents for the identification and reporting of LSVRO incidents as well as prevention strategies are discussed.

Towards a structured understanding of caregivers' safety behaviour in the domestic and driveway setting

Slow speed run-overs represent a major cause of injury and death among Australian children, with higher rates of incidents being reported in Queensland than in the remaining Australian states. Yet, little attention has been given to how caregivers develop their safety behaviour in and around the driveway setting. To address this gap, the current study aimed to develop a conceptual model of driveway child safety behaviours among caregivers of children aged 5 years or younger. Semi-structured interviews were conducted with 26 caregivers (25 females/1 male, mean age, 33.24 years) from rural and metropolitan Queensland. To enable a comparison and validation of findings from the driveway, the study analysed both driveway and domestic safety behaviours. Domestic safety behaviours were categorised and validated against driveway safety behaviours, uncovering a process of risk appraisal and safety behaviour that was applicable in both settings (the Safety System Model). However, noteworthy differences between the domestic and driveway setting were uncovered. Unlike in the domestic setting, driveway risks were perceived as shifting according the presence of moving vehicles, which resulted in inconsistent safety behaviours. While the findings require further validation, they have implications for the design and implementation of driveway run-over interventions.
