IntroductionAround 50 million people are killed or left disabled on the world's roads each year; most are in middle-income cities. In addition to this background risk, Baghdad has been plagued by decades of insecurity that undermine injury prevention strategies. This study aimed to determine death and disability and household consequences of road traffic injuries (RTIs) in postinvasion Baghdad.MethodsA two-stage, cluster-randomised, community-based household survey was performed in May 2014 to determine the civilian burden of injury from 2003 to 2014 in Baghdad. In addition to questions about household member death, households were interviewed regarding crash specifics, healthcare required, disability, relatedness to conflict and resultant financial hardship.ResultsNine hundred households, totalling 5148 individuals, were interviewed. There were 86 RTIs (16% of all reported injuries) that resulted in 8 deaths (9% of RTIs). Serious RTIs increased in the decade postinvasion and were estimated to be 26 341 in 2013 (350 per 100 000 persons). 53% of RTIs involved pedestrians, motorcyclists or bicyclists. 51% of families directly affected by a RTI reported a significant decline in household income or suffered food insecurity.ConclusionsRTIs were extremely common and have increased in Baghdad. Young adults, pedestrians, motorcyclists and bicyclists were the most frequently injured or killed by RTCs. There is a large burden of road injury, and the families of road injury victims suffered considerably from lost wages, often resulting in household food insecurity. Ongoing conflict may worsen RTI risk and undermine efforts to reduce road traffic death and disability.

Spontaneous combustion of coal is one of the major hazards threatening production safety during longwall mining. Mining-induced voids, which provide passages for air leakage, are the key factor triggering spontaneous combustion of coal in longwall goafs. In this study, a comprehensive method, which combined pressure balance, grouting injection, and filling fissures, was proposed to prevent spontaneous combustion of coal in longwall goafs with complex air leakage. Field engineering practice was carried out in Sitai Coal Mine in China. The results demonstrated that with the application of the proposed method, in the working face, the concentration of CO was decreased from 31ppm to 0 and the air leakage quantity was decreased from 261 to below 80 m3min-1. The gas samples analysis from the gob areas also indicated that concentrations of O2 and CO were successively decreased, indicating that the risk of spontaneous combustion of coal in goafs was eliminated. The above mentioned analysis indicates that, the method proposed in this study is useful and efficient. Successful application of this technology could provide reference for the treatment of other coal mines.

A study of different kinds of cycling facilities in Vancouver and Toronto, Canada, found that the safest kind of facility, by far, were cycle tracks, which are on-street bicycle lanes that are physically separated from motor vehicles by raised curbs, bollards, or concrete barriers.7 Compared with major streets with parked cars and no bicycle facilities, cycle tracks on roads without parked cars were 89% safer; regular, unprotected bicycle lanes on major roads without parked cars were 53% safer; and lightly trafficked residential streets without any bicycle facilities were 56% safer.

Low-level wind shear, i.e., sudden changes in wind speed and/or wind direction up to altitudes of 1600 ft (500 m) above-ground is a hazardous meteorological phenomenon in aviation. It may radically change the aerodynamic circumstances of the flight, particularly during landing and take-off and consequently, it may threaten human lives and the health of passengers, people at the airport and its surrounding areas. The Bratislava Airport, the site of this case study, is one of the few airports worldwide and the first in Central Europe that is equipped with a Doppler lidar system, a perspective remote sensing tool for detecting low-level wind shear. The main objective of this paper was to assess the weather events collected over a period of one year with the occurrences of low-level wind shear situations, such as vertical discontinuities in the wind field, frontal passages and gust fronts to increase the level of flight safety and protect human lives and health. The lidar data were processed by a computer algorithm with the main focus on potential wind shear alerts and microburst alerts, guided by the recommendations of the International Civil Aviation Organisation. In parallel, the selected weather events were analyzed by the nearby located meteorological radar to utilize the strengths of both approaches. Additionally, an evaluation of the lidar capability to scan dynamics of aerosol content above the airport is presented.

Evidence shows that there are many work-related accidents and injuries happening in construction projects and governments have taken a series of administrative measures to reduce casualties in recent years. However, traditional approaches have reached a bottleneck due to ignoring market forces, and thus new measures should be conducted. This study develops a perspective of safety performance (SP) for construction projects in China and puts forward a conception of the safety information system by using several brainstorming sessions to strengthen the safety supervision of participants in the construction industry. This system provides rating information to the public, and bad performance contractors enter into a blacklist which will influence their economic activities. Considering the limited rationality of government and various contractors, this paper builds a reasonable evolutionary game model to verify the feasibility of the safety information system. The analysis results show that there is not a single set of evolutionarily stable strategies (ESSs), as different situations may lead to different ESSs. The efficiency of applying the safety information system (the blacklist) in the construction industry can be proved by reducing the government’s safety supervision cost and by enhancing construction safety at the same time.

Falls are common adverse events following hospital discharge. However, prevention programs are not tailored for older patients transitioning home. To inform development of transitional fall prevention programs, nine older adults designated as being at risk of falls during hospitalization who were recently discharged home were asked about their perceptions of fall risk and prevention, as well as their knowledge and opinion of materials from the Centers for Disease Control and Prevention Stopping Elderly Accidents, Deaths & Injuries Initiative. Using the constant comparative method, five themes were identified: Sedentary Behaviors and Limited Functioning ; Prioritization of Social Involvement ; Low Perceived Fall Risk and Attribution of Risk to External Factors ; Avoidance and Caution as Fall Prevention ; and Limited Falls Prevention Information During Transition from Hospital to Home . Limited awareness of and engagement in effective fall prevention may heighten recently discharged older adults' risks for falls. Prevention programs tailored to the post-discharge period may engage patients in fall prevention, promote well-being and independence, and link hospital and community efforts.

American Indian (AI) children are disproportionately affected by unintentional injuries, with injury mortality rates approximately 2.3 times higher than the combined rates for all children in the United States. Although multiple risk factors are known to contribute to these increased rates, a comprehensive, culturally informed curriculum that emphasizes child safety is lacking for this population. In response to this need, academic and tribal researchers, tribal community members, tribal wellness staff, and national child safety experts collaborated to develop a novel child safety curriculum. This paper describes its development and community delivery. We developed the safety curriculum as part of a larger randomized controlled trial known as Healthy Children, Strong Families 2 (HCSF2), a family-based intervention targeting obesity prevention in early childhood (2–5 years). During the development of the HCSF2 intervention, participating tribal communities expressed concern about randomizing enrolled families to a control group who would not receive an intervention. To address this concern and the significant disparities in injuries and unintentional death rates among AI children, we added an active control group ( Safety Journey ) that would utilize our safety curriculum. Satisfaction surveys administered at the 12-month time point of the intervention indicate 94% of participants ( N  = 196) were either satisfied or very satisfied with the child safety curriculum. The majority of participants (69%) reported spending more than 15 min with the curriculum materials each month, and 83% thought the child safety newsletters were either helpful or very helpful in making changes to improve their family’s safety. These findings indicate these child safety materials have been well received by HCSF2 participants. The use of community-engaged approaches to develop this curriculum represents a model that could be adapted for other at-risk populations and serves as an initial step toward the creation of a multi-level child safety intervention strategy.

Although hospital falls and injuries are a significant patient safety concern, research is limited regarding falls and injuries in the emergency department. The purpose of this quality improvement project is to identify and implement evidence-based interventions to prevent patient falls and injuries in the emergency department. Literature was reviewed to identify best practices for fall prevention in the emergency department. Data sources included Journal Storage, PubMed, Cumulative Index for Nursing and Allied Health Literature, and Cochrane Database of Systematic Reviews. A retrospective chart review and root cause analysis was completed on fall-related risk reports over a 19-month period at a specific emergency department. Multifactorial fall prevention interventions were implemented in March 2017, which included nursing educational sessions, patient education handout, and high-fall-risk patient identification signs. Post-implementation, zero falls were sustained in April 2017. The average number of falls between April and December 2017 was 5.2 falls/month. Completion of the fall-risk assessment tool ranged between 47 to 90 percent. The patient education handout was provided up to 40 percent of the time. The use of fall risk signs outside patient rooms occurred up to 43 percent of the time. The emergency department is a unique environment with complex patient populations. Multifactorial interventions should be used to identify and prevent patient falls and injuries. Multiple change strategies and leadership support are essential to sustain changes. Future research should be conducted regarding the use of fall risk assessments and fall prevention strategies specific to the emergency department.

Background: Globally, falls in older people are a leading cause of injury-related mortality and morbidity. Cognitive impairment is a well-known risk factor for falls in this population group. While there is now a large body of evidence to support effective interventions for falls reduction across care settings, very little is known about interventions in the vulnerable, but increasing population of cognitively impaired community-dwelling older people. Therefore, the purpose of this systematic review is to investigate interventions designed to reduce falls in community-dwelling, cognitively impaired older adults. Methods: A literature search of databases was conducted to identify original research published in English, which met predefined inclusion and exclusion criteria for effective (non-pharmacological) falls prevention interventions in cognitively impaired community-dwelling people over 65 years of age. Data from the selected papers were extracted into data extraction tables and analyzed according to study characteristics, measures, results, and quality. Results: The review identified 11 studies providing data from 1,928 participants. Interventions included exercise, health assessment and management of risk, multi-component and cognitive behavioral programs, and hip protectors as falls risk reduction strategies. Seven of the selected studies showed an intervention effect in decreasing falls risk; however, only two of these showed a significant improvement in physical performance measures specifically in a cognitively impaired group. Conclusions: The diversity of interventions, study designs, populations, and quality of the studies, which met inclusion criteria, resulted in conflicting evidence and inconclusive results for falls prevention interventions in this highly complex population.

ObjectivesDeath from injury is frequently preventable, but injury remains a leading cause of death in the USA. While evidence-based strategies exist to prevent many types of injuries, effective policies for implementing these strategies at the population level are needed to reduce injury deaths. We identified promising injury prevention policies and evaluated their association with injury death rate (IDR).MethodsWe identified 11 injury prevention policies and accessed data on 2013 state and county IDRs. States were divided into strong, moderate and weak tertiles based on total number of policies in place. Adjusted regression modelling compared the strength of state prevention policies with IDRs at the state level and then at the county level to account for variability within states.ResultsThe strength of state prevention policies (tertile) was not significantly associated with IDR in US states. However, counties in strong policy states had a 11.8-point lower IDR compared with those in weak policy states (p=0.001).ConclusionsStates with more injury prevention policies in place have lower rates of death from injury, particularly when evaluated at the county level. Implementing recommended prevention policies holds potential to prevent injury death in the USA.
