Objective To examine the relationship between the numbers of people walking or bicycling and the frequency of collisions between motorists and walkers or bicyclists. The common wisdom holds that the number of collisions varies directly with the amount of walking and bicycling. However, three published analyses of collision rates at specific intersections found a non-linear relationship, such that collisions rates declined with increases in the numbers of people walking or bicycling. Data This paper uses five additional data sets (three population level and two time series) to compare the amount of walking or bicycling and the injuries incurring in collisions with motor vehicles. Results The likelihood that a given person walking or bicycling will be struck by a motorist varies inversely with the amount of walking or bicycling. This pattern is consistent across communities of varying size, from specific intersections to cities and countries, and across time periods. Discussion This result is unexpected. Since it is unlikely that the people walking and bicycling become more cautious if their numbers are larger, it indicates that the behavior of motorists controls the likelihood of collisions with people walking and bicycling. It appears that motorists adjust their behavior in the presence of people walking and bicycling. There is an urgent need for further exploration of the human factors controlling motorist behavior in the presence of people walking and bicycling. Conclusion A motorist is less likely to collide with a person walking and bicycling if more people walk or bicycle. Policies that increase the numbers of people walking and bicycling appear to be an effective route to improving the safety of people walking and bicycling. [ABSTRACT FROM AUTHOR]

The article presents news briefs related to injury prevention. According to a study by researchers in Toronto, Ontario, incidence of concussions is higher among female players than male players in soccer. An online paper, published in the periodical "Lancet," says that top three causes of death of young Americans in 2010 included unintentional injury, suicide and homicide. A study by the Violence Prevention Center says that gun violence prevention laws are related to gun death rates in the U.S.

Background Childhood falls are an important global public health problem, but there is lack of evidence about their prevention. Falls on one level result in considerable morbidity and they are costly to health services. Objective To estimate ORs for falls on one level in children aged 0-4 years for a range of safety behaviours, safety equipment use and home hazards. Design, setting and participants Multicentre case-control study at hospitals, minor injury units and general practices in and around four UK study centres. Participants included 582 children less than 5 years of age with a medically attended fall injury occurring at home and 2460 controls matched on age, sex, calendar time and study centre. Main outcome measure Fall on one level. Results Cases' most common injuries were bangs on the head (52%), cuts or grazes not needing stitches (29%) or cuts or grazes needing stitches (17%). Comparing cases to community controls in the adjusted analyses, significant findings were observed for only two exposures. Injured children were significantly less likely to live in a household without furniture corner covers (adjusted OR (AOR) 0.72, 95% CI 0.55 to 0.95), or without rugs and carpets firmly fixed to the floor (AOR 0.76, 95% CI 0.59 to 0.98). Conclusions We did not find any safety practices, use of safety equipment or home hazards associated with a reduced risk of fall on one level. Our findings do not provide evidence to support changes to current injury prevention practice. [ABSTRACT FROM AUTHOR]

Objective: To investigate whether the occupants in vehicles with better safety ratings according to EuroNCAP sustain fewer fatal and severe injuries than occupants in vehicles with worse experimental safety ratings when in frontal crashes. Design: Caseecontrol study. Setting: A representative sample of crashes in Britain from 1996 to 2008 as gathered in the Cooperative Crash Injury Study (CCIS) database under the auspices of the UK Department of Transportation and augmented with EuroNCAP experimental ratings for each crashed vehicle. Subjects: Drivers and front seat passengers while occupants of vehicles for which EuroNCAP test results were available and who met inclusion criteria meant to select those in crashes similar to those in the frontal experimental setting. Main outcome measures: Fatality and severe MAIS3+ injuries to the head, thorax, pelvis and lower extremities. Results: The multivariate Poisson regression models on the 1259 cases who sustained crash conditions most similar to the experimental ones showed no statistically significant effect on either mortality or MAIS3+ injury in real-world crashes when travelling in cars with better safety ratings. For example, when compared to a driver in a vehicle rated as safest for head injuries MAIS3+ in frontal crashes, drivers in vehicles rated yellow or orange presented adjusted ORs of 0.6 (0.2 to 1.7) and 0.8 (0.3 to 2.1), respectively. Conclusions: No statistically significant relationships between the EuroNCAP safety scores and real-world death or severe injury outcomes were found, suggesting the need to review biomechanical criteria chosen to set cut-off points for the rating system.

Introduction Suture needle handling methods vary extensively between units. Securing the needle tip by locking it against the shaft of the needle holder prior to transfer (protected method) has been suggested to improve safety, although this is not evidence based. Some teams prefer to transfer the needle mounted perpendicularly to the needle holders with the tip exposed (unprotected method). We investigated scrub nurses' preferred method of needle transfer, and noted the safety of each by investigating their experience of needlestick injuries (NSIs). Method Scrub nurses from Oxford University Hospitals Trust, Chelsea and Westminster and Wexham Park Hospitals were surveyed anonymously between November 2013 and August 2014. Nurses selected their preferred method (protected, unprotected or either), and indicated previous NSIs with either technique. Multinomial regression analysis and χ² with Yates correction were used to assess associations. Results One hundred and seven scrub nurses from 12 specialities were interviewed. 80/107 (75%) preferred protected transfer, 20/107 (19%) preferred unprotected transfer and 7/107 (6%) expressed no preference. There was no significant association between needle-mounting preference and years of scrub experience or speciality. Significant differences between preferences and four of the six hospitals were observed. Nine (9/107, 8%) scrub nurses reported NSIs with the protected method compared with 40 (40/107, 37%) in the unprotected group, this difference being statistically significant (p<0.001, χ²=25.17). Five (5/107, 5%) reported NSIs with both methods. Conclusions Protected needle transfer seems safer than the unprotected method. Needle-handling guidelines and appropriate training are required to help prevent the occurrence of NSIs in the operating theatre. [ABSTRACT FROM AUTHOR]

Background: Scalds are one of the most common forms of thermal injury in young children worldwide. Childhood scald injuries, which mostly occur in the home, result in substantial health service use and considerable morbidity and mortality. There is little research on effective interventions to prevent scald injuries in young children. Objectives: To determine the relationship between a range of modifiable risk factors for medically attended scalds in children under the age of 5 years. Design: A multicentre case-control study in UK hospitals and minor injury units with parallel home observation to validate parental reported exposures. Cases will be 0–4 years old with a medically attended scald injury which occurred in their home or garden, matched on gender and age with community controls. An additional control group will comprise unmatched hospital controls drawn from children aged 0–4 years attending the same hospitals and minor injury units for other types of injury. Conditional logistic regression will be used for the analysis of cases and matched controls, and unconditional logistic regression for the analysis of cases and unmatched controls to estimate ORs and 95% CI, adjusted and unadjusted for confounding variables. Main exposure measures: Use of safety equipment and safety practices for scald prevention and scald hazards. Discussion: This large case-control study will investigate modifiable risk factors for scalds injuries, adjust for potential confounders and validate measures of exposure. Its findings will enhance the evidence base for prevention of scalds injuries in young children. [ABSTRACT FROM AUTHOR]

Background: Childhood unintentional and suspected poisonings are a serious public health problem. Evidence from systematic reviews demonstrates that home safety education in combination with safety equipment provision increases the safe storage of medicines and other products. There is lack of evidence that poisoning prevention practices reduce poisoning rates. Objectives: To estimate ORs for medically attended poisonings in children aged 0–4 years for items of safety equipment, home hazards and parental safety practices aimed at preventing poisoning, and to explore differential effects by child and family factors. Design: Multicentre case-control study in UK hospitals with validation of parent-reported exposures using home observations. Cases are aged 0–4 years with a medically attended poisoning occurring at home, matched on age and sex with community controls. Children attending hospital for other types of injury will serve as unmatched hospital controls. Matched analyses will use conditional logistic regression; unmatched analyses will use unconditional logistic regression to adjust for confounding variables. The study requires 266 poisoning cases and 1064 matched controls to detect an OR of 0.64 for safe storage of medicinal products and of 0.65 for non-medicinal products, with 80% power, a 5% significance level and a correlation between exposures in cases and controls of 0.1. Main outcome measures: Unintentional childhood poisoning. Discussion: This will be the largest study to date exploring modifiable risk factors for poisoning in young children. Findings will inform: policy makers developing poison prevention strategies, practitioners delivering poison prevention interventions, parents to reduce the risk of poisoning in their homes.

Background: Priority setting, identification of unmet and changing healthcare needs, service and policy planning, and the capacity to evaluate the impact of health interventions requires valid and reliable methods for quantifying disease and injury burden. The methodology developed for the Global Burden of Disease (GBD) studies has been adopted to estimate the burden of disease in national, regional and global projects. However, there has been little validation of the methods for estimating injury burden using empirical data. Objective: To provide valid estimates of the burden of non-fatal injury using empirical data. Setting: Data from prospective cohort studies of injury outcomes undertaken in the UK, USA, Australia, New Zealand and The Netherlands. Design and participants: Meta-analysis of deidentified, patient-level data from over 40 000 injured participants in six prospective cohort studies: Victorian State Trauma Registry, Victorian Orthopaedic Trauma Outcomes Registry, UK Burden of Injury study, Prospective Outcomes of Injury study, National Study on Costs and Outcomes of Trauma and the Dutch Injury Patient Survey. Analysis: Data will be systematically analysed to evaluate and refine injury classification, development of disability weights, establishing the duration of disability and handling of cases with more than one injury in burden estimates. Developed methods will be applied to incidence data to compare and contrast various methods for estimating non-fatal injury burden. Contribution to the field: The findings of this international collaboration have the capacity to drive how injury burden is measured for future GBD estimates and for individual country or region-specific studies.

Background: Unintentional injury is the leading cause of preventable death in children in the UK, and 0-4- year-olds frequently attend emergency departments following injuries in the home. Parenting programmes designed to support parents, promote behaviour change and enhance parent-child relationships have been shown to improve health outcomes in children. It is not known whether group-based parenting programmes have the potential to prevent unintentional injuries in preschool children. Methods: A study to develop a group-based parenting programme to prevent unintentional home injuries in preschool children, and assess the feasibility of evaluation through a cluster-randomised controlled trial. The intervention, designed for parents of children who have sustained a medically attended injury, will be developed with two voluntary sector organisations. The feasibility study will assess ability to recruit parents, deliver the programme and follow-up participants. Participants will complete questionnaires at baseline, 3 months and 6 months, and report injuries in their preschool children using a tool designed and validated for this study. Qualitative methods will assess user and deliverer perceptions of the programme. Discussion: This study will develop the first group-based parenting programme to prevent injuries in preschool children, and design tools for parent-reported injury outcomes. A key challenge will be to recruit parents to participate in a manner that is nonstigmatising, and does not result in feelings of guilt or belief that they are perceived to be a bad parent. The findings will be used to prepare a trial to assess the effectiveness and cost-effectiveness of the intervention. [ABSTRACT FROM AUTHOR]

Objectives To estimate the likelihood of recovery at 1, 4 and 12 months post injury and investigate predictors of recovery in injured people attending an emergency department (ED) or admitted to hospital in the UK. Methods Participants completed questionnaires at recruitment and 1, 4 and 12 months post injury or until recovered. Data were collected on injury details, sociodemographic characteristics, general health prior to injury and recovery. We compared three age groups: 5-17, 18-64 and 65 years and above. Modified Poisson regression estimated the relative risk of recovery. Multivariable models were built using backward stepwise regression. Sensitivity analyses assessed the effect of missing data. Results We recruited 1517 participants, 55% (n=836) ED attenders and 44% (n=661) hospital admissions. By 1 month after injury, 28% (285/968) had fully recovered, 54% (440/820) at 4 months and 71% (523/738) at 12 months. Recovery was independently associated with gender, admission status, injury severity, body region injured and place of injury for 5-17 year olds and 18-64 year olds and with gender, admission status, injury severity and long-term illness for those aged 65+. Injury severity and hospital admission were associated with recovery across all age groups, but not at every time point in each age group. Other factors varied between age groups or time points. Results were generally robust to imputing missing data. Conclusions A range of factors was found to predict recovery among injured people. These could be used to identify those at risk of delayed recovery and to inform the design of interventions to maximise recovery. [ABSTRACT FROM AUTHOR]

PURPOSE: This prospective cohort study examined injuries and injury risk factors in 660 British Army infantry soldiers during a predeployment training cycle. METHODS: Soldiers completed a questionnaire concerning physical characteristics, occupational factors, lifestyle characteristics (including physical training time) and previous injury. Direct measurements included height, body mass, sit-ups, push-ups and run time. Electronic medical records were screened for injuries over a 1-year period before operational deployment. Backward-stepping Cox regression calculated HR and 95% CI to quantify independent injury risk factors. RESULTS: One or more injuries were experienced by 58.5% of soldiers. The new injury diagnosis rate was 88 injuries/100 person-years. Most injuries involved the lower body (71%), especially the lower back (14%), knee (19%) and ankle (15%). Activities associated with injury included sports (22%), physical training (30%) and military training/work (26%). Traumatic injuries accounted for 83% of all injury diagnoses. Independent risk factors for any injury were younger age (17–19 years (HR 1.0), 20–24 years (HR 0.71, 95% CI 0.55 to 0.93), 25–29 years (HR 0.89, 95% CI 0.66 to 1.19) and 30–43 years (HR 0.41, 95% CI 0.27 to 0.63), previous lower limb injury (yes/no HR 1.49, 95% CI 1.19 to 1.87) and previous lower back injury (yes/no HR 1.30, 95% CI 1.03 to 1.63). CONCLUSION: British infantry injury rates were lower than those reported for US infantry (range 101–223 injuries/100 soldier-years), and younger age and previous injury were identified as independent risk factors. Future efforts should target reducing the incidence of traumatic injuries, especially those related to physical training and/or sports. [ABSTRACT FROM AUTHOR]

Aims To assess the cost-effectiveness of installing thermostatic mixer valves (TMVs) in reducing risks of bath water scalds and estimate the costs of avoiding bath water scalds. Methods The evaluation was undertaken from the perspective of the UK public sector, and conducted in conjunction with a randomised control trial of TMVs installed in social housing in Glasgow. Installation costs were borne by the social housing organisation, while support materials were provided by the UK NHS. Effectiveness was represented by the number of families with at-risk bath water temperatures pre- and post-installation, and the number of bath scalds avoided as a result of installation. Differences in the number of families with at-risk temperatures between groups were derived from the RCT. Cost-effectiveness was assessed and a series of one-way sensitivity analyses were conducted. Results Unit costs associated with installation were calculated to be £13.68, while costs associated with treating bath water scalds ranged from £25 226 to £71 902. The cost of an avoided bath water scald ranged from net savings to public purse of £1887 to £75 520 and at baseline produced a net saving of £3 229 008; that is, £1.41 saved for every £1 spent. Conclusion It is very likely that installing TMVs as standard in social housing in new buildings and major refurbishments accompanied by educational information represents value for money.

Aim: To determine whether local politicians influence the distribution of traffic calming measures. Methods: Longitudinal ecological study in two UK cities. Local political constituencies were categorized by representation by members of the cabinet structure as a marker of influence. The density of traffic calming features per political area, adjusted for the historical pattern of road injuries, was compared between cabinet represented and non-represented areas. Results: Traffic calming density was significantly associated with cabinet representation status, adjusted for historical collision risk (risk ratio 2.77, 95% confidence interval 1 .37 to 5.61). Conclusion: These results support the hypothesis that senior local politicians are effective advocates for enhancing safety in their areas. [ABSTRACT FROM AUTHOR]

The article focuses on the history of accident prevention based on efforts to improve child safety and health in Great Britain. The absence of a concept of childhood before the industrial revolution, employment of children which led to waifs being unprotected and living on the streets, and passage of the 1802 Health and Morals of Apprentices Act are noted. Relations between various societies such as Royal Society for the Prevention of Accidents and Child Accident Prevention Trust are noted.
