Pedestrian Road Traffic Injuries in Urban Peruvian Children and Adolescents: Case Control Analyses of Personal and Environmental Risk Factors

BACKGROUND: Child pedestrian road traffic injuries (RTIs) are an important cause of death and disability in poorer nations, however RTI prevention strategies in those countries largely draw upon studies conducted in wealthier countries. This research investigated personal and environmental risk factors for child pedestrian RTIs relevant to an urban, developing world setting. METHODS: This is a case control study of personal and environmental risk factors for child pedestrian RTIs in San Juan de Miraflores, Lima, Perú. The analysis of personal risk factors included 100 cases of serious pedestrian RTIs and 200 age and gender matched controls. Demographic, socioeconomic, and injury data were collected. The environmental risk factor study evaluated vehicle and pedestrian movement and infrastructure at the sites in which 40 of the above case RTIs occurred and 80 control sites. FINDINGS: After adjustment, factors associated with increased risk of child pedestrian RTIs included high vehicle volume (OR 7.88, 95%CI 1.97-31.52), absent lane demarcations (OR 6.59, 95% CI 1.65-26.26), high vehicle speed (OR 5.35, 95%CI 1.55-18.54), high street vendor density (OR 1.25, 95%CI 1.01-1.55), and more children living in the home (OR 1.25, 95%CI 1.00-1.56). Protective factors included more hours/day spent in school (OR 0.52, 95%CI 0.33-0.82) and years of family residence in the same home (OR 0.97, 95%CI 0.95-0.99). CONCLUSION: Reducing traffic volumes and speeds, limiting the number of street vendors on a given stretch of road, and improving lane demarcation should be evaluated as components of child pedestrian RTI interventions in poorer countries

Children admitted to hospital following unintentional injury: perspectives of health service providers in Aotearoa/New Zealand

<p>Abstract</p> <p>Background</p> <p>Unintentional injuries are the leading cause of death and hospitalisation among New Zealand children, with indigenous Māori and ethnic minority Pacific children significantly over represented in these statistics. International research has shown that many children hospitalised for injury, as well as their families experience high levels of stress, and ethnic disparities in the quality of trauma care are not uncommon. The research on which this paper is based sought to identify key issues and concerns for New Zealand's multi-ethnic community following hospitalisation for childhood injury in order to inform efforts to improve the quality of trauma services. This paper reports on service providers' perspectives complementing previously published research on the experiences of families of injured children.</p> <p>Methods</p> <p>A qualitative research design involving eleven in-depth individual interviews and three focus groups was used to elicit the views of 21 purposefully selected service provider key informants from a range of professional backgrounds involved in the care and support of injured children and their families in Auckland, New Zealand. Interviews were transcribed and data were analysed using thematic analysis.</p> <p>Results</p> <p>Key issues identified by service providers included limited ability to meet the needs of children with mild injuries, particularly their emotional needs; lack of psychological support for families; some issues related to Māori and Pacific family support services; lack of accessible and comprehensive information for children and families; poor staff continuity and coordination; and poor coordination of hospital and community services, including inadequacies in follow-up plans. There was considerable agreement between these issues and those identified by the participant families.</p> <p>Conclusions</p> <p>The identified issues and barriers indicate the need for interventions for service improvement at systemic, provider and patient levels. Of particular relevance are strategies that enable families to have better access to information, including culturally appropriate oral and written sources; improve communication amongst staff and between staff and families; and carefully developed discharge plans that provide care continuity across boundaries between hospital and community settings. Māori and Pacific family support services are important and need better resourcing and support from an organisational culture responsive to the needs of these populations.</p

Risk of disability due to car crashes: a review of the literature and methodological issues.

With improving rates of survival following road traffic injuries in many countries, healthy years of life lost due to crashes increasingly reflect the prevalence of disabling sequelae. This review examines the epidemiological evidence regarding the risk of disability due to car crashes, published between 1980 and 2002. Studies of sequelae limited to specific domains (e.g. head injury, whiplash, psychiatric morbidity) were excluded. Of the 19 studies meeting the criteria for review, most focused on the prevalence of disability following crashes but not the association between them. Prevalence estimates of post-crash disability varied from 2 to 87%. The potential sources of heterogeneity included differences in study settings and period, duration of follow-up, and definitions of exposure and outcome. Methodological problems that compounded the difficulties in interpretation and generalisability of study findings included selection biases and use of non-representative samples, idiosyncratic outcome measures, inadequate adjustment for confounding, and the prevailing medico-legal or compensation context. The findings highlight the need for well-designed population-based epidemiological studies using validated outcome measures and appropriate comparison groups to determine the independent risk of disability due to car crashes. The review also revealed a critical need for data from low- and middle-income countries, the setting for over 90% of the estimated global burden of road traffic injury

A population-based cohort study of longer-term changes in health of car drivers involved in serious crashes.

STUDY OBJECTIVE: Evidence about the burden of disability after motor vehicle crashes has relied primarily on trauma center-based studies. We examine the impact of serious crashes on the longer-term health of car drivers, independent of natural variation, in a population-based study in Auckland, New Zealand. METHODS: The study population comprised 218 car drivers surviving nonfatal crashes in Auckland, in which at least 1 occupant in the vehicle was admitted to a hospital, and a representative sample of 254 car drivers in the region, recruited from roadside surveys. All participants were interviewed at recruitment (subjects reported their precrash health) and 5 and 18 months later. The drivers' changes in health were obtained with a global health transition indicator and the Short Form-36, with analyses adjusting for potential confounders. RESULTS: Compared with 7% of drivers in the comparison group, 43% of crash drivers admitted to the hospital (adjusted odds ratio 10.4; 95% confidence interval 5.5 to 19.6) and 20% of those not admitted (odds ratio 3.3; 95% confidence interval 1.4 to 8.3) reported that their overall health at 18-month follow-up was worse than at baseline (precrash). Among the drivers reporting worsened health, prospectively ascertained Short Form-36 scores revealed greater reductions in physical health in those admitted after the crash, but these scores improved from 5 to 18 months. In contrast, mental and general health scores worsened from 5 to 18 months in admitted and nonadmitted crash drivers. CONCLUSION: A substantial proportion of drivers surviving serious crashes experience reductions in longer-term health, a burden likely to be underappreciated among those not admitted to a hospital. Emergency departments could serve as useful settings in which to develop and validate clinical decision rules that can help target services for crash survivors at increased risk of adverse outcomes
