BACKGROUND: The mortality rate from road traffic injuries has increased in sub-Saharan Africa as the number of motor vehicles increase. This study examined the capacity of hospitals along Malawi's main north-south highway to provide emergency trauma care.METHODS: Structured interviews and checklists were used to evaluate the infrastructure, personnel, supplies, and equipment at all four of Malawi's central hospitals, ten district hospitals, and one mission hospital in 2014. Most of these facilities are along the main north-south highway that spans the country.RESULTS: Between July 2013 and March 2014, more than 9 200 road traffic injuries(RTIs) and 100 RTI deaths were recorded by the participating hospitals. All of the hospitals reported staff shortages, especially during nights and weekends. Few clinicians had completed formal training in emergency trauma management, and healthcare workers reported gaps in knowledge and skills, especially at district hospitals. Most central hospitals had access to the critical supplies and medications necessary for trauma care, but district hospitals lacked some of the supplies and equipment needed for diagnosis, treatment, and personal protection.CONCLUSION: The mortality and disability burden from road traffi c injuries in Malawi(and other low-income countries in sub-Saharan Africa) can be reduced by ensuring that every central and district hospital has a dedicated trauma unit with qualified staff who have completed primary trauma care courses and have access to the equipment necessary to save lives. 展开更多

Purpose:Road traffic accidents pose a global challenge with substantial human and economic costs.Iranexperiences a high incidence of road traffic injuries,leading to a significant burden on society.This studyaims to predict the future burden of road traffic injuries in Iran until 2030,providing valuable insights forpolicy-making and interventions to improve road safety and reduce the associated human and economiccosts.Methods:This analytical study utilized time series models,specifically autoregressive integrated movingaverage(ARIMA)and artificial neural networks(ANNs),to predict the burden of road traffic accidents byanalyzing past data to identify patterns and trends in Iran until 2030.The required data related toprevalence,death,and disability-adjusted life years(DALYs)rates were collected from the Institute forHealth Metrics and Evaluation database and analyzed using R software and relevant modeling andstatistical analysis packages.Results:Both prediction models,ARIMA and ANNs indicate that the prevalence rates(per 100,000)of allroad traffic injuries,except for motorcyclist road injuries which have an almost flat trend,remaining ataround 430,increase by 2030.Based on estimations of both models,the rates of death and DALYs due tomotor vehicle and pedestrian road traffic injuries decrease.For motor vehicle road injuries,estimatedtrends decrease to approximately 520 DALYs and 10 deaths.Also,for pedestrian road injuries these ratesreached approximately 300 DALYs and 6 deaths,according to the models.For cyclists and other roadtraffic injuries,the predicted DALY rates by the ANN model increase to almost 50 and 8,while predictionsconducted by the ARIMA model show a static trend,remaining at 40 and approximately 6.5.Moreover,these rates for the prediction of death rate by the ANN model increased to 0.6 and 0.1,while predictionsconducted by the ARIMA model show a static trend,remaining at 0.43 and 0.07.According to the ANNmodel,the predicted rates of DALY and death for motorcyclists decrease to 100 and approximately 2.7,respectively.On the other hand,predictions made by the ARIMA model show a static trend,with ratesremaining at 200 and approximately 3.2,respectively.Conclusion:The prevalence of road traffic injuries is predicted to increase,while the death and DALYrates of road traffic injuries show different patterns.Effective intervention programs and safety measuresare necessary to prevent and reduce road traffic accidents.Different interventions should be designedand implemented specifically for different groups of pedestrians,cyclists,motorcyclists,and motorvehicle drivers. 展开更多

Background Among the deaths due to trauma, about one half of the patients suffer from road traffic injury (RTI). Most of RTI patients complicate acute respiratory distress syndrome (ARDS) and severe multiple injuries. ARDS is a major contributor to morbidity and mortality in trauma patients. Although many injuries and conditions are believed to be associated with ARDS independent risk factors in trauma patients, their relative importance in development of the syndrome are undefined. We hypothesize that not all of the traditional risk factors impacting mortality are independently associated with patients strictly identified by traffic injury. This study aimed to sieve distinctive risk factors in our RTI population, meanwhile, we also hypothesize that there may exist significantly different risk factors in these patients.Methods This was a retrospective cohort study regarding RTI as a single cause for emergency intensive care unit (EICU) admission. Patients identified as severe RTI with post-traumatic ARDS were enrolled in a prospectively maintained database between May 2002 and April 2007 and observed. Twenty-three items of potential risk impacting mortality were calculated by univariate and multivariate Logistic analyses in order to find distinctive items in these severe RTI patients. Results There were 247 RTI patients with post-traumatic ARDS admitted to EICU during the study period. The unadjusted odds ratio (OR) and 95% confidence intervals (CI) of mortality were associated with six risk factors out of 23: APACHE II score, duration of trauma factor, pulmonary contusion, aspiration of gastric contents, sepsis and duration of mechanical ventilation. The adjusted ORs with 95% Cl were denoted with respect to surviving beyond 96 hours EICU admission (APACHE II score, duration of trauma factor, aspiration of gastric contents), APACHE II score beyond 20 EICU admission (duration of trauma factor, sepsis, duration of mechanical ventilation) and mechanical ventilation beyond 7 days EICU admission (duration of trauma factor and sepsis). Conclusions We have retrospectively demonstrated an adverse effect of six different risk factors out of 23 items in mortality of post-traumatic ARDS within severe RTI patients and, moreover, gained distinct outcomes in stratified patients under real emergency trauma circumstance. An impact of APACHE II score and pulmonary contusion contributing to prediction of mortality may exist in prophase after traffic injury. Sepsis is still a vital risk factor referring to systemic inflammatory response syndrome, infection, and secondary multiple organs dysfunction. Eliminating trauma factors as early as possible becomes the critical therapeutic measure. Aspiration of gastric contents could lead to incremental mortality due to severe ventilation associated pneumonia. Long-standing mechanical ventilation should be constrained on account of severe refractory complications. 展开更多

Purpose:This research examined road traffic injury mortality and morbidity disparities across of country development status,and discussed the possibility of reducing country disparities by various actions to accelerate the pace of achieving Sustainable Development Goals target 3.6 e to halve the number of global deaths and injuries from road traffic accidents by 2020.Methods:Data for road traffic mortality,morbidity,and socio-demographic index(SDI)were extracted by country from the estimates of the Global Burden of Disease study,and the implementation of the three types of national actions(legislation,prioritized vehicle safety standards,and trauma-related post-crash care service)were extracted from the Global Status Report on Road Safety byWorld Health Organization.We fitted joinpoint regression analysis to identify and quantify the significant rate changes from 2011 to 2017.Results:Age-adjusted road traffic mortality decreased substantially for all the five SDI categories from 2011 to 2017(by 7.52%e16.08%).Age-adjusted road traffic mortality decreased significantly as SDI increased in the study time period,while age-adjusted morbidity generally increased as SDI increased.Subgroup analysis by road user yielded similar results,but with two major differences during the study period of 2011 to 2017:(1)pedestrians in the high SDI countries experienced the lowest mortality(1.68e1.90 per 100,000 population)and morbidity(110.45e112.72 per 100,000 population for incidence and 487.48e491.24 per 100,000 population for prevalence),and(2)motor vehicle occupants in the high SDI countries had the lowest mortality(4.07e4.50 per 100,000 population)but the highest morbidity(428.74e467.78 per 100,000 population for incidence and 1025.70e1116.60 per 100,000 population for prevalence).Implementation of the three types of national actions remained nearly unchanged in all five SDI categories from 2011 to 2017 and was consistently stronger in the higher SDI countries than in the lower SDI countries.Lower income nations comprise the heaviest burden of global road traffic injuries and deaths.Conclusion:Global road traffic deaths would decrease substantially if the large mortality disparities across country development status were reduced through full implementation of proven national actions including legislation and law enforcement,prioritized vehicle safety standards and trauma-related postcrash care services. 展开更多

Background: Life-threatening bleeding is a major cause of trauma-related deaths. Stop the Bleed—Active bleeding control (ABC) program in Hyderabad recently showed that lay first responders can be effectively trained. However, the willingness of high school students to train in bleeding control is unknown. We report Stop the Bleed training needs assessment from high schools in India and estimate the potential multiplier effect. Methods: A cross-sectional survey was conducted from 12 randomly selected schools in Hyderabad. The study was to understand current knowledge, skills and willingness to get trained and respond to life-threatening bleeding from injuries. 107 Participants (35 Teachers and 72 students) were purposively selected for telephonic interviews with a structured questionnaire. Results: Response rate was 93% overall. 80% of participants have never been trained in bleeding control. 84% reported willingness to be trained, train others and help bleeding victims. All the teachers reported that stop the bleed training would be useful in high schools. 70.6% of teachers recommended that training could start from middle school (10 to 15 years), 47% preferred the online training mode. Only 20% of participants had prior training in lifesaving first aid and 32% did not know the number of emergency medical services (EMS). Each trained participant has the potential to train 3 to 4 people at the household level and perhaps more at the community level. Conclusion: The surveyed schools in Hyderabad do not have the knowledge, skills, or training curriculum in Stop the Bleed. Students and teachers are willing to be trained and train others, with great potential for a “multiplier-effect” in the community. 展开更多

Background Road traffic injuries (RTIs) are a worldwide issue associated with increasing development and motorization. However, statistical studies do not include any analyses of Beijing's geriatric population. Using data from the Beijing Emergency Medical Center, we present the main characteristics of traffic injuries involving the elderly in Beijing. We also provide objective information for those concerned with the safety of traffic systems and the prevention of traffic injuries. Methods In a longitudinal, retrospective study, data were collected on 1706 victims aged 65 years and older who sustained traffic injuries in Beijing between 2004 and 2010. Personal information, time of injury event, emergency care response time, road user type, striking vehicle type, injury site, and severity of injury were analyzed using ;~2 tests and Logistic regression analysis. Results The annual rate of traffic injuries was 21.80 per 100 000 elderly people in Beijing, and the morbidity rate decreased from 2004 to 2010 (P 〈0.001). The mean age was (72.92+5.67) years, and 911 (53.40%) of the victims were male. The majority of victims sustained head and lower limb injuries and were classified as being of medium severity. Traffic collisions occurred most frequently in the daytime excluding rush hours; these collisions included being hit by a car (85.64%) and pedestrian victim injuries (79.19%). Our statistical analysis found three factors for injury severity: abdominal injuries (P 〈0.001), number of injury sites (P=0.027), and head injuries (P=0.034). The decline in traffic injuries is due to a decrease in victims aged 65-74 years and pedestrians; the sevedty of RTIs also decreased. Conclusions This study highlights the declining trend in traffic injuries among older adults in Beijing. However, traffic injuries remain a serious public health problem for the elderly and effective measures are required to reduce their incidence. 展开更多

Purpose: Successful application experiences on public-private partnership (PPP) in different countries, suggest that PPP could be an option in road traffic injury (RTI) prevention. The present study aims at investigating the applicability of PPP policy in RTI prevention in Iran based on the experts’ perspectives.Methods: This is a qualitative study with grounded theory approach which has been conducted in Tabriz University of Medical Sciences, Iran in 2018. The participants were 22 experts in the field of RTIs selected using purposive sampling method. Data were collected by semi-structured interviews and analyzed with content-analysis method.Results: The results were classified under 5 main themes (applicability, scopes and services, challenges, advantages, and strategies) for applying PPP policy and 37 sub-themes. Due to the prevalence of RTIs, the present challenges in public sector, existence of qualified private sector, and successful experiences in other areas, there are opportunities for private sector partnership in prevention of RTIs. Private sector could participate in different scopes and services regarding RTI prevention, including road construction and maintenance, maintenance and provision of vehicles safety and public education. The main challenges including legislation issues, ambiguities in collaboration, political and organizational unsustain-ability, government’s financial hardship and lack of experienced experts in the field of RTI. However, there are significant advantages including high efficiency in program implementation, covering the weaknesses of public sector, effective and efficient management on application of PPP in RTI prevention. The strategies include identifying and prioritizing the assignable activities, identifying the qualified private sector, developing PPP policies and legal frameworks, creating a common language between public and private parties, trying to meet the expectations of the private sector by public sector, developing a comprehensive and sound contract, and cultivating public culture to accept private sector in the field of RTI prevention.Conclusion: This study sought to determine whether PPP could be used as strategy to reduce the burden of RTIs in Iran. But it requires a lot of preliminary studies to provide the context and conditions for applying this policy. 展开更多

Background: A few studies have been conducted to determine the relationship between road motor vehicle crashes (MVC) and serious injuries related to tiredness, fatigues and sleeping. Aim: To determine the effects of aggressive behaviour, driver sleepiness and fatigue on MVC and related injuries among Turkish population. Design and setting: Population-based case and control study conducted at the accident emergency departments of hospitals and roads. Subjects: 515 car drivers involved in crashes with injury were admitted to hospital and 1030 car drivers involved while driving on public roads as control group during the study period. Methods: The Manchester driver behaviour questionnaire (DBQ) measured the aberrant driving behaviours leading to accidents. Participants completed a fatigue severity scale (FSS) and Stanford Sleeping questionnaire an epworth scale with items related to socio-demographic information, driving experiences, adherence to traffic laws (such as speed limits and seat belt), and drivers' driving records. Results: In a representative sampling, participant's age ranged from 25 to 65 and the mean and standard deviation were 36.5 _+ 7.8 for cases and 37.0 4- 8.0 for controls. There was a significant difference in both group of drivers regarding BMI, level of education, marital status, driving experience, seat belt use, excessive speed limits, physical activity number of sleeping hours, mobile phone use, and cigarette smoking habit (p = 0.017). Also, there was a significant higher mean score on all the DBQ violation questions among case group in comparison with the control group (p 〈 0.001). Further, cases had higher prevalence of Epworth sleeping disorders (p 〈 0.001) and fatigue severity (p - 0.003) compared to control drivers. Multivariate logistic regression revealed that excessive speed, fatigue, lapses, errors, Stanford sleepiness score, violations, mobile phone use and Epworth sleepiness scale were significantly associated with injury involvement in vehicle crash, after adjusting for driving experience and annual mileage. Conclusion: The current study confirmed that drivers with chronic fatigue, acute sleepiness, and careless driver behavior may significantly increases the risk of road crash which can be lead to serious injury. 展开更多
