Comparing fatal crash risk factors by age and crash type by using machine learning techniques.

This study aims to use machine learning methods to examine the causative factors of significant crashes, focusing on accident type and driver's age. In this study, a wide-ranging data set from Jeddah city is employed to look into various factors, such as whether the driver was male or female, where the vehicle was situated, the prevailing weather conditions, and the efficiency of four machine learning algorithms, specifically XGBoost, Catboost, LightGBM and RandomForest. The results show that the XGBoost Model (accuracy of 95.4%), the CatBoost model (94% accuracy), and the LightGBM model (94.9% accuracy) were superior to the random forest model with 89.1% accuracy. It is worth noting that the LightGBM had the highest accuracy of all models. This shows various subtle changes in models, illustrating the need for more analyses while assessing vehicle accidents. Machine learning is also a transforming tool in traffic safety analysis while providing vital guidelines for developing accurate traffic safety regulations.

Effect of Rural Trauma Team Development on the Outcomes of Motorcycle Accident-Related Injuries (Motor Registry Project): Protocol for a Multicenter Cluster Randomized Controlled Trial.

BACKGROUND: Injury is a global health concern, and injury-related mortality disproportionately impacts low- and middle-income countries (LMICs). Compelling evidence from observational studies in high-income countries shows that trauma education programs, such as the Rural Trauma Team Development Course (RTTDC), increase clinician knowledge of injury care. There is a dearth of such evidence from controlled clinical trials to demonstrate the effect of the RTTDC on process and patient outcomes in LMICs. OBJECTIVE: This multicenter cluster randomized controlled clinical trial aims to examine the impact of the RTTDC on process and patient outcomes associated with motorcycle accident-related injuries in an African low-resource setting. METHODS: This is a 2-arm, parallel, multi-period, cluster randomized, controlled, clinical trial in Uganda, where rural trauma team development training is not routinely conducted. We will recruit regional referral hospitals and include patients with motorcycle accident-related injuries, interns, medical trainees, and road traffic law enforcement professionals. The intervention group (RTTDC) and control group (standard care) will include 3 hospitals each. The primary outcomes will be the interval from the accident to hospital admission and the interval from the referral decision to hospital discharge. The secondary outcomes will be all-cause mortality and morbidity associated with neurological and orthopedic injuries at 90 days after injury. All outcomes will be measured as final values. We will compare baseline characteristics and outcomes at both individual and cluster levels between the intervention and control groups. We will use mixed effects regression models to report any absolute or relative differences along with 95% CIs. We will perform subgroup analyses to evaluate and control confounding due to injury mechanisms and injury severity. We will establish a motorcycle trauma outcome (MOTOR) registry in consultation with community traffic police. RESULTS: The trial was approved on August 27, 2019. The actual recruitment of the first patient participant began on September 01, 2019. The last follow-up was on August 27, 2023. Posttrial care, including linkage to clinical, social support, and referral services, is to be completed by November 27, 2023. Data analyses will be performed in Spring 2024, and the results are expected to be published in Autumn 2024. CONCLUSIONS: This trial will unveil how a locally contextualized rural trauma team development program impacts organizational efficiency in a continent challenged with limited infrastructure and human resources. Moreover, this trial will uncover how rural trauma team coordination impacts clinical outcomes, such as mortality and morbidity associated with neurological and orthopedic injuries, which are the key targets for strengthening trauma systems in LMICs where prehospital care is in the early stage. Our results could inform the design, implementation, and scalability of future rural trauma teams and trauma education programs in LMICs.

The development of a road safety policy index and its application in evaluating the effects of road safety policy.

The paper presents an exploratory study of a road safety policy index developed for Norway. The index consists of ten road safety measures for which data on their use from 1980 to 2021 are available. The ten measures were combined into an index which had an initial value of 50 in 1980 and increased to a value of 185 in 2021. To assess the application of the index in evaluating the effects of road safety policy, negative binomial regression models and multivariate time series models were developed for traffic fatalities, fatalities and serious injuries, and all injuries. The coefficient for the policy index was negative, indicating the road safety policy has contributed to reducing the number of fatalities and injuries. The size of this contribution can be estimated by means of at least three estimators that do not always produce identical values. There is little doubt about the sign of the relationship: a stronger road safety policy (as indicated by index values) is associated with a larger decline in fatalities and injuries. A precise quantification is, however, not possible. Different estimators of effect, all of which can be regarded as plausible, yield different results.

[Epidemic characteristics and trend analysis of major injuries deaths among children and adolescents in Jiangsu Province from 2012 to 2021].

Objective: To understand the situation and epidemic characteristics of injury deaths among children aged 5 to 24 years in Jiangsu Province from 2012 to 2021 and the trend of annual changes. Methods: The main injury mortality data of children and adolescents was collected, and the crude and standardized mortality rates of road traffic accidents, drowning, suicide, and accidental falls among children and adolescents over a decade and the annual average percentage of change (AAPC) were calculated. The main injury mortality characteristics and trends of children and adolescents of different age groups and genders were analyzed. Results: The total number of injury deaths among 5 to 24 adolescents in Jiangsu Province was 16 052, with a standardized mortality rate of 9.58/100 000. There was no significant trend in the overall standardized mortality rate of injuries (AAPC=-3.450%, P=0.055). The standardized mortality rate of road traffic injuries among children and adolescents showed a decreasing trend over the past decade, with statistical significance (AAPC=-9.406%, P<0.001). The standardized suicide mortality rate showed an upward trend over the past decade, with statistical significance (AAPC=9.000%, P=0.001). The overall injury mortality rate showed an upward trend with age. Suicide rates in males and females were on the rise and both have statistical significance (AAPC=9.420% and AAPC=9.607%, both P<0.05). The standardized mortality rates of female traffic accidents, drowning, and male traffic accidents showed a decreasing trend and were statistically significant (AAPC for female traffic accidents=-7.364%, AAPC for female drowning=-5.352%, and AAPC for male traffic accidents=-10.242%, all P<0.05). The standardized mortality rate of urban and rural traffic accidents showed a decreasing trend and was statistically significant(AAPC=-7.899% and AAPC=-9.421%, both P<0.001). The standardized suicide mortality rate showed an upward trend and statistical significance (AAPC=11.009% and AAPC=7.528%, both P<0.05). Conclusions: The overall injury situation of children and adolescents in Jiangsu Province improved in the past decade from 2012 to 2021, but the suicide mortality rate was on the rise. It is necessary to focus on the mental health issues of this age group and to strengthen the prevention and control of suicide among children and adolescents, in Jiangsu.

Risk of road traffic injury in Norway 1970-2022.

This paper describes changes in the risk of road traffic injury in Norway during the period from 1970 to 2022. During this period, the risk of fatal and personal injury declined by more than 70 % for most groups of road users. There are five main potential explanations of a decline in the risk of injury: (1) a reduced probability of accidents that have the potential for causing injury; (2) an improved protection against injury given that an accident has occurred; (3) improved medical care increasing the survival rate, given an injury (this would reduce the number of fatalities, but not the number of injuries); (4) a tendency for the reporting of injuries in official accident statistics to decline over time; (5) uncertain or erroneous estimates of the exposure to the risk of injury. The decline in the risk of road traffic injuries in Norway after 1970 can probably be attributed to a combination of reduced reporting of injuries in official statistics, improved protection against injury in accidents, and (for fatal injuries) improved medical care. Insurance data, available from 1992, do not indicate a reduction in the risk of accidents leading to insurance claims. Incomplete and possibly erroneous data for mopeds and motorcycles make it impossible to identify sources of changes in injury risk over time for these modes of transport.

Safety performance of dedicated and preferential bus lanes using multivariate negative binomial models for Bogotá, Colombia.

Public transport priority systems such as Bus Rapid Transit (BRT) and Buses with High Level of Service (BHLS) are top-rated solutions to mobility in low-income and middle-income cities. There is scientific agreement that the safety performance level of these systems depends on their functional, operational, and infrastructure characteristics. However, there needs to be more evidence on how the different characteristics of bus corridors might influence safety. This paper aims to shed some light on this area by structuring a multivariate negative binomial model comparing crash risk on arterial roads, BRT, and BHLS corridors in Bogotá, Colombia. The analyzed infrastructure includes 712.1 km of arterial roads with standard bus service, 194.1 km of BRT network, and 135.6 km of BHLS network. The study considered crashes from 2015 to 2018 -fatalities, injuries, and property damage only- and 30 operational and infrastructure variables grouped into six classes -exposure, road design, infrastructure, public means of transport, and land use. A multicriteria process was applied for model selection, including the structure and predictive power based on [i] Akaike information criteria, [ii] K-fold cross-validation, and [iii] model parsimony. Relevant findings suggest that in terms of observed and expected accident rates and their relationship with the magnitude of exposure -logarithm of average annual traffic volumes at the peak hour (LOG_AAPHT) and the percentage of motorcycles, cars, buses, and trucks- the greatest risk of fatalities, injuries, and property damage occurs in the BHLS network. BRT network provides lower crash rates in less severe collisions while increasing injuries and fatalities. When comparing the BHLS network and the standard design of arterial roads, BHLS infrastructure, despite increasing mobility benefits, provides the lowest safety performance among the three analyzed networks. Individual factors of the study could also contribute to designing safer roads related to signalized intersection density and curvature. These findings support the unique characteristics and traffic dynamics present in the context of Bogotá that could inform and guide decisions of corresponding authorities in other highly dense urban areas from developing countries.

The Global Road Traffic Death Rate and Human Development Index from 2000 to 2019: A Trend Analysis.

BACKGROUND: Numerous studies on the association between the human development index (HDI) and road traffic death rate (RTDR) merely focus on developed countries, not reflecting the relationship between the HDI components and RTDR in a time-trend analysis. Accordingly, this study analyzes the trends of RTDR and their association with the HDI and its components from 2000 to 2019. METHODS: The RTDR data of 154 countries were imported into the unconditional latent growth model (LGM) to assess the RTDR trends. The impact of the HDI and its components (viz., education, income, and life expectancy [LE viz]) on the trajectory of RTDR was also evaluated using the conditional LGM. RESULTS: The results of the unconditional LGM indicated an overall decreasing trend in RTDR. The conditional LGM results revealed the negative effect of the HDI and its components on the model parameters. The findings of random forests indicated that education and LE were the most crucial variables. CONCLUSION: Overall, this study emphasizes the significance of HDI and its components, particularly education and LE, in lowering the number of traffic fatalities. In this sense, improving formal education and LE could be one of the main policies that policymakers could consider to reduce RTDR.

Road vehicle collision suicide in Australia: Trends, collision types, and individual characteristics.

BACKGROUND: Suicide by road vehicle collision in Australia is under-explored with mixed findings. We aimed to address this research gap by examining time trends, different types of vehicle collision, and individual characteristics related to vehicle-collision suicide. METHOD: We retrospectively analyzed deaths by suicide between 1st January 2001 and 31st December 2017 in Australia, using coronial records from the National Coronial Information System. The travel mode used and collision counterpart were retrieved from records of death by vehicle-collision suicide using all available information. We conducted negative binomial regression analysis to examine annual changes in suicide rate by vehicle collision on a public road (N = 640) and other methods of suicide (N = 41,890), and logistic regression analysis to examine individual characteristics associated with the likelihood of dying by suicide via road vehicle collision. RESULTS: Overall, the national suicide rate involving road vehicle collision significantly increased, while the rate by other methods significantly decreased. Drivers accounted for 61% of suicide events by vehicle collision, of which 72% were single-vehicle collisions (commonly involving a tree). For multiple-vehicle collision suicide events, 82% involved collision with a truck. Pedestrians accounted for more than one-third of suicide events, of which 58% involved collision with a truck and 23% involved collision with a car/van. Individuals who were male (odds ratio 1.15; 95% CI 0.88-1.50), aged <25 years old (odds ratio 5.27; 95% CI 3.05-9.10), non-Indigenous (odds ratio 3.36; 95% CI 1.71-6.62), and born overseas (odds ratio 1.40; 95% CI 1.10-1.79) were more likely to die by vehicle-collision suicide than by other methods of suicide. CONCLUSIONS: This study provides a better understanding of road vehicle collision suicide in Australia and informs future research directions on topic. Our findings can be used to inform suicide prevention initiatives to reduce vehicle-collision suicide deaths.

The effect of opioid use on traffic fatalities.

We use a difference-in-differences design to study the effect of opioid use on traffic fatalities. Following Alpert et al., we focus on the 1996 introduction and marketing of OxyContin, and we examine its long-term impacts on traffic fatalities involving Schedule II drugs or heroin. Based on the national fatal vehicle crash database, we find that the states heavily targeted by the initial marketing of OxyContin (i.e., non-triplicate states) experienced 2.4 times more traffic fatalities (1.6 additional deaths per million individuals) involving Schedule II drugs or heroin during 2011-2019, when overdose deaths from heroin and fentanyl became more prominent. We find no difference in traffic fatalities until after the mid-2000s between states with and without a triplicate prescription program. The effect is mainly concentrated in fatal crashes with drug involvement of drivers ages between 25 and 44. Our results highlight additional long-term detrimental consequences of the introduction and marketing of OxyContin.

Working towards 2030 road safety targets, the need for specific rural and remote children strategies.

INTRODUCTION: Despite the importance of child road traffic death, the knowledge about rural child road traffic death in Australia is limited. OBJECTIVE: To explore the difference of child road traffic death between urban and rural areas. DESIGN: This study was a retrospective analysis of road traffic death in Australia among children and adolescents aged 0-19 registered between 1 January 2009 and 30 June 2019. RESULTS: During the study period, there were 1757 child road traffic death in Australia, and the crude mortality rate was 2.96 per 100 000 population. The crude mortality rate in remote (8.83 per 100 000 population) and very remote (11.08 per 100 000 population) areas was much higher than major cities (1.83 per 100 000 population), inner regional (5.14 per 100 000 population) and outer regional (5.91 per 100 000 population). CONCLUSIONS: Specific targets are needed to address the burden of child road traffic death in Australia around rurality, as it is a significant risk factor of child road traffic death.

Mortalidad en accidentes por moto en Venezuela, y su relación con Políticas Públicas de seguridad vial y preventiva,1996-2018 / Mortality in motorcycle accidents in Venezuela and relationship with public road safety and preventive policies, 1996 - 2018

Los accidentes de tránsito son un problema de salud pública de gran magnitud y gravedad, en las Américas; Venezuela ocupa un lugar destacado por su alta incidencia. El objetivo de la investigación es establecer la relación entre las políticas públicas para la prevención de los accidentes de motocicletas, y las tasas de mortalidad. Metodología: Estudio documental retrospectivo de las políticas viales y las tasas de mortalidad específicas de lesionados por accidentes de motocicletas en Venezuela durante el período 1996-2018. Resultados: como causa de muerte en Venezuela (2000-2018), representa casi 7% del total, entre 6 a 50% del total de las muertes por accidentes de tránsito terrestre y se mantiene muy alta al final del período, con fallecidos por motocicletas sobre 25%. La elevación de la curva endémica de mortalidad ocurrió simultáneamente al aumento en la producción e importación de motocicletas, y cayó durante la crisis económica, en el año 2014. La legislación actualizada mas no acatada en esta materia, es notoria Conclusiones: Los accidentes de motocicleta son un problema de salud pública de primer orden en Venezuela asociadas al clima económico y social, las tasas de mortalidad tuvieron su máxima meseta de elevación durante la bonanza petrolera 2005-2013. Las políticas asociadas a la prevención de accidentes viales en moto están fragmentadas, son ineficientes y reactivas a situaciones complejas, deficientemente aplicadas por los organismos de tránsito responsables a escala nacional, regional y municipal.

Introduction. Traffic accidents are a public health problem of great magnitude and gravity in the Americas; Venezuela occupies a prominent place for its high incidence. The objective of the research is to establish the relationship between public policies for the prevention of motorcycle accidents, and mortality rates. Methodology: Retrospective documentary study of road policies and specific mortality rates of those injured by motorcycle accidents in Venezuela during the period 1996-2018. Descriptive statistical analysis with trend lines, frequency distributions and annual average rates. Results: cause of death in Venezuela (2000-2018), represents almost 7% of the total. The burden of motorcycle injury deaths represents between 6 to 50% of total road traffic fatalities and remains very high at the end of the period, with motorcycle fatalities over 25%. The elevation of the endemic mortality curve occurred simultaneously with the increase in the production and import of motorcycles, and fell concomitantly with the economic crisis in 2014. Conclusions: Motorcycle accidents are a public health problem of the first order in Venezuela associated with the economic and social climate, mortality rates had their maximum plateau of elevation during the oil economic boom 2005-2013. The policies associated with the prevention of road accidents by motorcycle are fragmented, inefficient and reactive to complex situations and poorly applied by the responsible traffic agencies at national, regional and municipal level.

Big data on the prevalence of injury deaths among 187 488 elderly Chinese in the past 20 years (2000-2020): a systematic review and meta-analysis.

BACKGROUND: This study systematically reviewed injury death and causes in the elderly population in China from 2000 to 2020, to prevent or reduce the occurrence of injuries and death. METHODS: The CNKI, VIP, Wan Fang, MEDLINE, Embase, SinoMed, and Web of Science databases were searched to collect epidemiological characteristics of injury death among elderly over 60 years old in China from January 2000 to December 2020. Random effects meta-analysis was performed to pool injury mortality rate and identify publication bias, with study quality assessed using the AHRQ risk of bias tool. RESULTS: (1) A total of 41 studies with 187 488 subjects were included, covering 125 million elderly. The pooled injury mortality rate was 135.58/105 [95%CI: (113.36 to 162.14)/105], ranking second in the total death cause of the elderly. (2)Subgroup analysis showed that male injury death (146.00/105) was significantly higher than that of females (127.90/105), and overall injury mortality increased exponentially with age (R2 = 0.957), especially in those over 80 years old; the spatial distribution shows that the injury death rate in the central region is higher than that in the east and west and that in the countryside is higher than that in the city; the distribution of death time shows that after entering an aging society (2000-2020) is significantly higher than before (1990-2000). (3) There are more than 12 types of injury death, and the top three are falling, traffic accidents, and suicide. CONCLUSIONS: China's elderly injury death rate is at a high level in the world, with more males than females, especially after the age of 80. There are regional differences. The main types of injury death are falling, traffic, and suicide. During the 14th Five-Year Plan period, for accidental injuries and death, a rectification list for aging and barrier-free environments was issued. PROSPERO REGISTRATION: The systematic review was registered in PROSPERO under protocol number CRD42022359992.

Examining the Trends in Motor Vehicle Traffic Deaths in New York City, 1999-2020.

Monitoring and understanding the trends in motor vehicle traffic (MVT) mortality is crucial for developing effective interventions and tracking progress in reducing deaths related to MVT. This study aimed to assess the trends in MVT mortality in New York City from 1999 through 2020. Publicly available de-identifiable mortality data were abstracted from the Centers for Disease Control and Prevention's Wide-ranging Online Data for Epidemiologic Research. MVT deaths were identified using the International Classification of Diseases Codes, 10th Revision: V02-V04 (.1, .9), V09.2, V12-V14 (.3-.9), V19 (.4-.6), V20-V28 (.3-.9), V29-V79 (.4-.9), V80 (.3-.5), V81.1, V82.1, V83-V86 (.0-.3), V87 (.0-.8), and V89.2. Age adjusted mortality rates (AAMR) were abstracted by county (Bronx; Kings; Queens; New York), age (in years) (< 25; 25-44; 45-64; ≥ 65), sex (male; female), race/ethnicity (Non-Hispanic Black; Non-Hispanic White; Asian/Pacific Islander; Hispanic), and road user type (motor vehicle occupant; motorcyclist; pedal cyclist; pedestrian). Joinpoint regression models were fitted to estimate the annual percentage change (APC) and average annual percentage change (AAPC) in AAMR during the study period. The Parametric Method was used to compute 95% confidence intervals (CI). Between 1999 and 2020, a total of 8,011 MVT deaths were recorded in New York City. Mortality rates were highest among males (age adjusted mortality rate (AAMR) = 6.4 per 100,000; 95% CI: 6.2, 6.5), Non-Hispanic Blacks (AAMR = 4.8; 95% CI: 4.6, 5.0), older adults (AAMR = 8.9; 95% CI: 8.6, 9.3), and persons from Richmond County (AAMR = 5.2; 95% CI: 4.8, 5.7). MVT death rates, overall, have declined by 3% per year (95% CI: -3.6, -2.3) from 1999 to 2020. The rates have fallen or stabilized by race/ethnicity, county of residence, road user type, and age group. In contrast, rates have increased by 18.1% per year among females and by 17.4% per year in Kings County from 2017 to 2020.The results of this study draw attention to the worsening trends in MVT mortality among females and in Kings County, New York City. Further investigation is needed to determine the underlying behavioral, social, and environmental factors contributing to this increase, such as polysubstance or alcohol abuse, psychosocial stressors, access to medical and emergency care, and compliance with traffic laws. These findings emphasize the importance of developing targeted interventions to prevent MVT deaths and ensure the health and safety of the community.

Incomplete decapitation with exenteration of the brain in a motorcyclist run over by a semitrailer.

Although decapitation is a well-known traumatic mechanism in road traffic deaths, incomplete decapitation of a motorcyclist with exenteration of the brain has not yet been reported in the forensic literature in a victim run over by a vehicle. This paper deals with an autopsy case of a 69-year-old motorcyclist, who had been run over by a semitrailer, as a result of which flattening of the head with extrusion of the brain and incomplete decapitation occurred at the level of the fourth cervical vertebra. This constellation allows to define a special mechanism of accident-related decapitation. Moreover, the case underlines the importance of a multidisciplinary approach for the reconstruction of the accident as well as for the assessment of its judicial consequences. On the suspicion of a hit-and-run accident, simulation tests were performed by technical experts. These tests revealed that the motorcycle may not have been conspicuous for the truck driver prior to and during the accident. Consequently, the charge of manslaughter and failure to render assistance against the truck driver was dropped.

Impact of high temperature on road injury mortality in a changing climate, 1990-2019: A global analysis.

BACKGROUND: Previous studies have shown that extreme heat likely increases the risk of road injuries. However, the global burden of road injuries due to high temperature and contributing factors remain unclear. This study aims to characterize the global, regional and national burden of road injuries due to high temperature from 1990 to 2019. METHODS: Based on the Global Burden of Disease (GBD) study 2019, we obtained the numbers and age-standardized mortality rates (ASMR) and age-standardized disability-adjusted life years (DALY) rates (ASDR) of the road injury due to high temperature at global, regional, and national levels from 1990 to 2019. The world is divided into five climate zones according to the average annual temperature of each country: tropical, subtropical, warm temperate, cold temperate, and boreal. We used the generalized additive models (GAM) to model the trends of road injuries globally and by region. RESULTS: Globally, between 1990 and 2019, the deaths of road injury attributable to high temperature increased significantly from 20,270 (95% uncertainty interval [UI], 7836 to 42,716) to 28,396 (95% UI, 13,311 to 51,178), and the DALYs increased from 1,169,309 (95% UI, 450,834 to 2,491,075) to 1,414,527 (95% UI, 658,347 to 2,543,613). But the ASMR and the ASDR slightly decreased by 8.49% and 13.16%, respectively. The burden of road injury death attributable to high temperature remained high in low SDI and tropical regions. In addition, road transport infrastructure investment per inhabitant is associated with the burden of road injuries attributable to high temperature. CONCLUSIONS: Globally, the ASMR and ASDR for road injuries attributable to high temperature decreased from 1990 to 2019, but the absolute death and DALYs continued to increase. Thus, concerning global warming, implementation of prevention and interventions to reduce road injuries from heat exposure should be stressed globally.

Desigualdades sociales relacionadas con la mortalidad por accidentes de tráfico / Social inequalities related to road traffic mortality

Objetivo: Sintetizar las desigualdades sociales relacionadas con la mortalidad por accidentes de tráfico reportadas en publicaciones científicas. Método: Se realizó una revisión exploratoria de la literatura siguiendo la guía PRISMA-ScR. Utilizando el vocabulario MesH se hizo una búsqueda sistemática de artículos publicados en inglés, portugués y español en las bases de datos EBSCO, Scielo, Scopus, Ovid y PubMed. Resultados: Se identificaron 47.790 registros en la búsqueda inicial, de los cuales 35 artículos cumplieron los criterios de selección. Nueve de cada diez publicaciones son de países de altos ingresos y existe un mayor interés en el análisis de la mortalidad en ocupantes y conductores de automotores. La mitad de las publicaciones utilizan la raza, la etnia y la geolocalización como variables de posición socioeconómica. Los artículos incluidos en esta revisión indican que las agrupaciones de personas de baja posición socioeconómica presentan una mayor mortalidad por accidentes de tránsito. Conclusiones: La mayor mortalidad por accidentes de tránsito se presenta en personas de baja posición socioeconómica, lo que sugiere el desarrollo de acciones de seguridad vial que estén vinculadas con otras agendas políticas a fin de reducir su incidencia para 2030. A pesar de que la mortalidad por accidentes de tránsito es mayor en los países de medianos y bajos ingresos, son pocas las publicaciones realizadas en ellos, por lo que se requiere fortalecer las capacidades de investigación en tales países.(AU)

Objective: To synthesize the social inequalities related to mortality from traffic accidents reported in scientific publications. Method: A scoping review following the PRISMA-ScR guide was carried out. Using the MesH vocabulary, we systematically searched for articles in English, Portuguese and Spanish published in the EBSCO, Scielo, Scopus, Ovid, and PubMed databases. Results: We identified 47,790 records in the initial search, of which 35 articles met the selection criteria. Nine out ten publications are in high-income countries; there is a greater interest in analyzing mortality in occupants and drivers of vehicles and motorcyclists. Half of the publications use race-ethnicity and geolocation as socioeconomic position variables. The articles included in this review indicate that groups of people with low socioeconomic positions have higher mortality due to traffic accidents. Conclusions: The highest mortality from traffic accidents occurs in people with low socioeconomic positions which suggests the development of road safety actions from a comprehensive, integrative perspective and linked to other political agendas to reduce their incidence by 2030. Although road traffic fatalities are higher in low and middle-income countries, few publications are available in these countries.

Determinantes sociales de la salud en los accidentes de tránsito en Honduras 2019 / Social determinants of health of traffic accidents in Honduras 2019

Antecedentes: En Honduras, los accidentes de tránsito (AT) se han incrementado en los últimos años, representando un problema para la salud pública nacional y mundial. Las muertes por AT según la Dirección Nacional de Vialidad y Transporte (DNVT) incrementaron en 23% entre 2020 y 2021. Objetivo: Caracterizar los determinantes sociales de la salud de muertes y lesiones por accidentes de tránsito en Honduras. Métodos: Estudio cuantitativo descriptivo, retrospectivo, basado en fuentes secundarias de AT a nivel nacional de la DNVT Honduras, 2019. Resultados: De 4,778 personas accidentadas, el sexo masculino representó 85.9% fallecidos y 75.2% lesiones. De cada diez personas que sufrieron lesiones, siete correspondieron al sexo masculino. El grupo etario con mayor número de fallecidos fue de 25 a 34 años. El mayor número de AT correspondió a los departamentos: Cortés y Francisco Morazán. La principal causa fue atropellamiento y colisión. La mayor ocurrencia fue los fines de semana en 35.9% y en el mes de diciembre por la tarde- noche. Tipo de vehículo más involucrado: transporte mediano, uso particular y motorizado, usuarios más vulnerables: peatones y conductores. Las principales causas de mortalidad fueron: exceso de velocidad, imprudencia del conductor y del peatón y obstrucción de vía pública. Discusión. Los determinantes sociales de la salud pueden influir sobre la ocurrencia y aumentar el riesgo de algunos individuos para morir o lesionarse a causa de AT, en Honduras al igual que otros países, se carece de información que relacione determinantes inherentes al accidente con una mirada completa a través de determinantes sociales de la salud...8AU)

Incidence and Risk of Fatal Vehicle Crashes Among Professional Drivers: A Population-Based Study in Taiwan.

Fatal vehicle crashes (FVCs) are among the leading causes of death worldwide. Professional drivers often drive under dangerous conditions; however, knowledge of the risk factors for FVCs among professional drivers remain scant. We investigated whether professional drivers have a higher risk of FVCs than non-professional drivers and sought to clarify potential risk factors for FVCs among professional drivers. We analyzed nationwide incidence rates of FVCs as preliminary data. Furthermore, by using these data, we created a 1:4 professionals/non-professionals preliminary study to compare with the risk factors between professional and non-professional drivers. In Taiwan, the average crude incidence rate of FVCs for 2003-2016 among professional drivers was 1.09 per 1,000 person-years; professional drivers had a higher percentage of FVCs than non-professional drivers among all motor vehicle crashes. In the 14-year preliminary study with frequency-matched non-professional drivers, the risk of FVCs among professional drivers was significantly associated with a previous history of involvement in motor vehicle crashes (adjustment odds ratio [OR] = 2.157; 95% confidence interval [CI], 1.896-2.453), previous history of benzodiazepine use (adjustment OR = 1.385; 95% CI, 1.215-1.579), and speeding (adjustment OR = 1.009; 95% CI, 1.006-1.013). The findings have value to policymakers seeking to curtail FVCs.
