RESUMO
Nine in 10 road traffic deaths occur in low- and middle-income countries (LMICs). Despite this disproportionate burden, few studies have examined built environment correlates of road traffic injury in these settings, including in Latin America. We examined road traffic collisions in Bogotá, Colombia, occurring between 2015 and 2019, and assessed the association between neighborhood-level built environment features and pedestrian injury and death. We used descriptive statistics to characterize all police-reported road traffic collisions that occurred in Bogotá between 2015 and 2019. Cluster detection was used to identify spatial clustering of pedestrian collisions. Adjusted multivariate Poisson regression models were fit to examine associations between several neighborhood-built environment features and rate of pedestrian road traffic injury and death. A total of 173,443 police-reported traffic collisions occurred in Bogotá between 2015 and 2019. Pedestrians made up about 25% of road traffic injuries and 50% of road traffic deaths in Bogotá between 2015 and 2019. Pedestrian collisions were spatially clustered in the southwestern region of Bogotá. Neighborhoods with more street trees (RR, 0.90; 95% CI, 0.82-0.98), traffic signals (0.89, 0.81-0.99), and bus stops (0.89, 0.82-0.97) were associated with lower pedestrian road traffic deaths. Neighborhoods with greater density of large roads were associated with higher pedestrian injury. Our findings highlight the potential for pedestrian-friendly infrastructure to promote safer interactions between pedestrians and motorists in Bogotá and in similar urban contexts globally.

BACKGROUND: Although road traffic injuries and deaths have decreased globally, there is substantial national and sub-national heterogeneity, particularly in low- and middle-income countries (LMICs). Ghana is one of few countries in Africa collecting comprehensive, spatially detailed data on motor vehicle collisions (MVCs). This data is a critical step towards improving roadway safety, as accurate and reliable information is essential for devising targeted countermeasures. METHODS: Here, we analyze 16 years of police-report data using emerging hot spot analysis in ArcGIS to identify hot spots with trends of increasing injury severity (a weighted composite measure of MVCs, minor injuries, severe injuries, and deaths), and counts of injuries, severe injuries, and deaths along major roads in urban and rural areas of Ghana. RESULTS: We find injury severity index sums and minor injury counts are significantly decreasing over time in Ghana while severe injury and death counts are not, indicating the latter should be the focus for road safety efforts. We identify new, consecutive, intensifying, and persistent hot spots on 2.65% of urban roads and 4.37% of rural roads. Hot spots are intensifying in terms of severity and frequency on major roads in rural areas. CONCLUSIONS: A few key road sections, particularly in rural areas, show elevated levels of road traffic injury severity, warranting targeted interventions. Our method for evaluating spatiotemporal trends in MVC, road traffic injuries, and deaths in a LMIC includes sufficient detail for replication and adaptation in other countries, which is useful for targeting countermeasures and tracking progress.

INTRODUCTION: An injury is described as any damage to the body that impairs health, and its severity can span from mild to life-threatening. On a global scale, injuries account for approximately 4.4 million deaths annually and are anticipated to become the seventh leading cause of death by 2030. In Ethiopia, injuries account for 7% of all deaths, with one of the world's highest rates of road traffic injuries. This study, undertaken at a primary trauma centre in the capital of Ethiopia, aimed to explore the characteristics of injured patients and emergency department mortality as the patient outcome. Understanding the patterns and outcomes of injuries helps to anticipate needs, prioritize patients, and allocate resources effectively. METHODS: A retrospective single-center observational study utilised patient records from September 2020 to August 2021 at Addis Ababa Burn Emergency and Trauma Hospital, located in Ethiopia. A structured checklist facilitated the data collection. All patients arriving in the ED from September 2020 to August 2021 were eligible for the study while incomplete records (missing > 20% of wanted data elements) were excluded. RESULT: Of the 3502 injured patients recorded during the study period, 317 were selected. The mean patient age was 30 years, with 78.5% being male. About 8% arrived the emergency department within an hour after the injury. Ambulances transported 38.8% of patients; 58.5% of these were referred from other facilities. The predominant mechanism of injury both in and outside Addis Ababa was pedestrian road traffic injuries (31.4% and 38%). The predominant injury type was fractures (33.8%). The mortality rate was 5%, of which half were pedestrian road traffic incidents. CONCLUSION: Pedestrian road traffic injuries were the main cause of injury in and outside of Addis Ababa. A small proportion of patients arrived at the emergency department within the first hour after an injury event. A significant proportion of ambulance-transported patients were referred from other facilities rather than directly from the scene. The overall mortality rate was high, with pedestrian road traffic injury accounting for half of the proportion.

PURPOSE: With the increasing level of automation in automobiles, the advent of autonomous vehicles has reduced the tendency of drivers and passengers to focus on the task of driving. The increasing automation in automobiles reduced the drivers' and passengers' focus on driving, which allowed occupants to choose a more relaxed and comfortable sitting position. Meanwhile, the occupant's sitting position went from a frontal, upright position to a more relaxed and reclined one, which resulted in the existing restraint systems cannot to keep occupants safe and secure. This study aimed to determine the effects of different reclining states on occupants' lumbar and neck injuries. METHODS: This is an original research on the field of automotive safety engineering. Occupants in different initial sitting positions (25°, 35°, 45°, and 55°) were adapted to changes in seat back angle and restraint systems and placed in the same frontal impact environment. Neck injury indexes, lumbar axial compression force and acceleration, as well as occupant dynamic response during the impact, were compared in different sitting positions. The injury response and kinematic characteristics of occupants in different reclining positions were analyzed by the control variable method. RESULTS: As the sitting angle increased, the occupant's head acceleration decreased, and the forward-lean angle decreased. Occupants in the standard sitting position had the greatest neck injury, with an Nij of 0.95, and were susceptible to abbreviated injury scale 2+ cervical medullary injuries. As the seatback angle increased, the geometric position of the lumbar spine tended to be horizontal, and the impact load transmitted greater forces to the lumbar spine. The occupant's lumbar injury was greatest in the lying position, with a peak axial compression force on the lumbar region of 5.5 KN, which was 2.3 KN greater than in the standard sitting position. CONCLUSION: The study of occupant lumbar and neck injuries based on different recline states can provide a theoretical basis for optimizing lumbar evaluation indexes, which is conducive to the understanding of the lumbar injury mechanism and the comprehensive consideration of occupant safety protection.

OBJECTIVE: Driving under the influence (DUI) of alcohol is a major risk factor for fatal road traffic injuries (RTIs) worldwide. This study aimed to investigate the relationship between the implementation of new acts on DUI of alcohol and the clinical outcomes of patients with severe RTIs in Korea. METHODS: This is a community-based cross-sectional study using a nationwide severe trauma registry in Korea. In 2018, 2 acts with the Yoon Chang-Ho Act (Yoon's Act) were passed to strengthen the punishment for drunk driving fatal RTIs (first Yoon's act) and lower the blood alcohol concentration limit to restrict driver's licenses (second Yoon's act). The first Yoon's act was implemented on December 18, 2018, and the second Yoon's act was implemented on June 25, 2019. The study periods were categorized as pre-Act-1, pre-Act-2, Act-1, and Act-2 according to the application of Yoon's Act, and the study outcome was in-hospital mortality. Multivariable logistic regression analysis was conducted to estimate the relationship of the new acts and in-hospital mortality. RESULTS: Among a total of 20,376 patients with severe RTIs and 7,928 patients (drivers) with RTIs (hereafter drivers), the in-hospital mortality rates were 20.8% and 17.0%, and alcohol-related RTIs accounted for 9.7% and 8.1%, respectively. Severe RTIs tended to increase with each period (25.5 cases/day, 24.5 cases/day, 26.8 cases/day, and 30.4 cases/day, P for trend <.01). In-hospital mortality significantly decreased during the Act-2 period compared to the pre-Act-2 period for all patients with severe RTIs (adjusted odds ratio = 0.54, 95% confidence interval 0.43-0.67) and drivers with RTIs (adjusted odds ratio = 0.50, 95% confidence interval 0.34-0.73). CONCLUSIONS: Implementation of the new acts on DUI of alcohol was associated with lower odds for in-hospital mortality for patients with severe RTIs. Further studies are needed to evaluate the long-term impact of the new acts on reducing alcohol-related RTIs.
RESUMO
Limited data are available in Mexico on the prevalence of alcohol and drug use and the possible differences in their effects on types of road traffic injury (RTI), such as those involving pedestrians, drivers or passengers of motorcycles or other motor vehicles, and the association between substance use and driving behaviors, for preventive purposes. The sample comprised 433 adult RTI patients, admitted to the emergency department (ED) of a public hospital in Mexico City (January to April 2022). Breath Alcohol Concentration (BAC) was measured using a breath tester, and six types of drugs (amphetamines, barbiturates, benzodiazepines, cannabis, cocaine, and methamphetamine) were assessed using a saliva screen test. RTI patients also self-reported their alcohol and drug use in the six hours prior to the accident. Approximately 62% of respondents had been involved in a motorcycle crash. One in three patients self-reported or had traces of a substance in their saliva or breath. The most common substance was alcohol (23.6%), followed by cannabis and stimulants (10.9%). One in five patients reported having used a cell phone ten minutes before the injury. One in three had not been using any safety device, the only behavior exacerbated by substance use. We found a high prevalence of substance use in the sample of RTI patients admitted to the ED, regardless of the type of the RTI, together with high cell phone rates. Motorcycle passengers under the influence were particularly likely not to have been wearing a helmet.

Background: Distraction is one of the main driver's behavioral factors that reduces the performance of the drivers and might increase the accident risk. Distraction while driving holds significant importance, especially among professional drivers, and failure to address this matter may result in adverse implications for traffic safety. The present study was conducted to investigate distraction and related risk factors between two groups of private vehicle drivers and taxi drivers. Methods: This analytical cross-sectional study was carried out in Tabriz, Iran in 2022. The total sample size in this study was 701 taxi drivers, professional drivers, and private vehicle drivers. The independent samples t-test was used to determine the statistically significant difference between groups and its sub-scales between the two studied groups. Moreover, the multivariable linear regression analysis was used to determine the predictors that affect distraction score. The test's level of significance was considered at 0.05. Results: The mean distraction score among taxi drivers surpasses that of private vehicle drivers (2.82 vs. 2.32, p-value<0.05). The drivers with negative scores, over the past year, among private vehicle drivers and taxi drivers were 2.5 % and 5.2 %, respectively (p-value<0.05). A group of taxi drivers exhibits a higher level of distraction while driving and the mean distraction score for private vehicle drivers is lower than that of taxi drivers (ß = -0.11, CI 95 %: 0.17, -0.05). Also, a history of damage or injury accidents has a significant impact on distraction while driving (ß = 0.12, CI 95 %; 0.06-0.17). Conclusions: The results indicate that distraction while driving is high amongst taxi drivers rather than private vehicle drivers. To have effective driver safety promotion interventions, it is recommended to consider driver distraction based on professional and non-professional drivers.
RESUMO
Previous studies have demonstrated health impacts of climate change, but evidence on heatwaves' associations with road traffic injury (RTI) is limited. In this study, individual information of RTI cases in May-September during 2006-2021 in China were obtained from the National Injury Surveillance System. Daily maximum temperatures (TMmax) during 2006-2021 were collected from the ERA-5 reanalysis, and the projected daily TMmax during 2020-2099 were obtained from the latest Coupled Model Intercomparison Project Phase 6 Shared Socioeconomic Pathways scenarios (SSPs). We used a time-stratified case-crossover analysis to investigate the association between short-term exposure (lag01 days) to heatwaves (exceeding the 92.5th percentile of daily TMmax for ≥ three consecutive days) and RTI, and to project heatwave-related RTI until 2099 across China. Finally, a total of 1 031 082 RTI cases were included in the analyses. Compared with non-heatwaves, the risks of RTI increased by 3.61 % during heatwaves. Greater associations were found in people aged 15-64 years, in people with transportation occupation, for non-motor traffic vehicle injuries, for severe RTI cases, and in Western China particularly in Qinghai province. We projected substantial increases in attributable fraction (AF) of heatwave-related RTI in the future, particularly in Western and Southwest China. The national average increase in AF (per decade) during 2020s-2090s was 0.036 % for SSP1-2.6 scenario, and 0.267 % for SSP5-8.5 scenario. This study provided evidence on the associations of heatwaves with RTI, and the heatwave-related RTI will substantially increase in the future.

Background: Being injured in a road traffic accident may affect individuals' functional ability and in turn lead to sickness absence (SA) and disability pension (DP). Knowledge regarding long-term consequences in terms of SA and DP following a road traffic accident is lacking, especially comparing different groups of road users and compared to the general population. The aim was to estimate excess diagnosis-specific SA and DP among individuals of different road user groups injured in a road traffic accident compared to matched references without such injury. Methods: A nationwide register-based study, including all working individuals aged 20-59 years and living in Sweden who in 2015 had in- or specialized outpatient healthcare after a new traffic-related injury (n = 20 177) and population-based matched references (matched on: sex, age, level of education, country of birth, living in cities) without any traffic-related injury during 2014-2015 (n = 100 885). Diagnosis-specific (injury and other diagnoses) SA and DP were assessed during 5 years: 1 year before and 4 years following the accident. Mean SA and DP net days/year for each road user group and mean differences of (excess) SA and DP net days/year compared with their matched references were calculated with independent t-tests with bootstrapped 95% confidence intervals (CIs). Results: A third of all injured road users were bicyclists, 31% were car occupants, 16% were pedestrians (including fall accidents), and 19% were other and unspecified accidents. Pedestrians and other road users were the groups with the highest mean number of SA days during the first year following the accident (51 and 49 days/year respectively). The matched references had between 8 and 13 SA days/year throughout the study period. The excess SA days/year were elevated for all road user groups all five studied years. Excess SA due to injury diagnoses was 15-35 days/year during the first year following the accident. Excess SA due to diagnoses other than injuries were about eight days/year during the whole study period for pedestrians and car occupants and about zero for the bicyclists. The excess DP was low, although it increased every year after the accident for pedestrians and car occupants; for bicyclists no excess DP was seen. Conclusion: Higher levels of SA due to injury diagnoses were seen among all road user groups during the first year after the accident compared to their references. Pedestrians and car occupants had more excess SA due to other diagnoses and more excess DP four years after the accident than bicyclists and other road users.
RESUMO
OBJECTIVE: The use of motorcycles in commercial transportation is increasing due to its comfortable use in congested traffic conditions and the ease of parking on narrow streets. Motorcycle couriers are among the important members of the delivery industry. The race against time and delivering on time bring along many problems. This study aims to examine the relationships between perceived organizational support, colleague value and stress in motor courier employees. METHOD: Within the scope of the study, 151 motorcycle couriers working in the delivery sector were selected. The study was carried out in the period of June-November 2022. In addition to 15 questions including demographic characteristics with the one-to-one interview method, Spielberger's State and Trait Anxiety Scale, The Perceived Organizational Support Scale and The Coworker Support Scale were applied with the one-to-one interview method. RESULTS: The average age of the 151 couriers included in the study was 29.10 ± 7.01; the working year was 3.26 ± 3.39; the average number of daily trips was 36.47 ± 17.37; the average delivery time was 16.54 ± 10.10 in minutes (median 15); and the average weight of the cargo was 4.94 ± 5.51 (kg) (median: 3.50). The prevalence of occupational accidents in the last year has been 43.3% (n = 61). Examining the causes of the prevalence of accident among the study population, it was found that motorcycle overturning was 20 (32.8%); vehicle hitting the motorcycle was 26 (42.6%); motorcycle hitting the vehicle was 15 (24.6%). When the factors affecting the perceived organizational support were examined, it was found that those with a colleague social support score above 18 were more likely to have an organizational perception score above 80 (95% CI 1.001-4.843) with a rate of [OR] = 2.20 times higher, and those with a status anxiety score above 40 were more likely to have an organizational perception score over 80 with a rate of [OR] = 2.49 times higher (95% CI: 1.156-5.364). In addition, it was seen that the probability of having an organizational perception score above 80 was [OR] = 0.42 times higher (95%CI: 0.200-0.889) in participants who had a work accident. CONCLUSIONS: The intense pace of work and the pressure of fast delivery increase couriers' state and trait concerns. Developing policies to improve the psychosocial working environment for a more decent and healthier working environment that improves the mental health and well-being of couriers is recommended. Commercial food ordering platforms must treat driver safety as important when determining delivery times.

INTRODUCTION: This study aims to analyze the clinical characteristics, demographic features, and injury circumstances of patients admitted to the Emergency Department (ED) at Fondazione Policlinico Universitario A. Gemelli (IRCCS) in Rome, Italy, due to bicycle accidents. METHODS: Data on clinical characteristics, accident timing, injury circumstances, and helmet use were collected for ED patients involved in bicycle accidents from January 2019 to December 2022. Subsequently, Abbreviated Injury Scale codes of all diagnoses were recorded and the Injury Severity Score was calculated. RESULTS: Over the study period, 763 patients were admitted to the ED following bicycle accidents, with a 0.3 % fatality rate and a 30.4 % frequency of multitrauma. Multivariate analysis revealed that collisions with other vehicles increased trauma severity and the risk of ICU admission. Conversely, helmet use was associated with reduced severity of head trauma and a lower likelihood of ICU admission. Notably, toxicological investigations were not conducted for any ED-admitted patients. CONCLUSIONS: Although a low mortality rate and a low incidence of multi-trauma have been shown in comparison to other nations, it is necessary to adopt prevention strategies like safety devices, more cycle paths, and better infrastructures on the one hand, and stricter laws on the other. It is essential to require toxicological testing in Italy for all accidents involving this means of transport, and to make helmet use compulsory for all ages.

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.

OBJECTIVE: The visual guiding system, as a tunnel traffic safety improvement method by using visual guiding facilities to actively guide driving safely, has been widely used in countries with many tunnels, in recent years. This paper aims to quantitatively study the comprehensive evaluation of traffic safety of the visual guiding system in tunnels, which has certain engineering application value and can provide support for the quantitative evaluation and optimal design of tunnel traffic safety. METHODS: Based on the analysis of the relevant factors of urban tunnel traffic safety, a multi-factor comprehensive evaluation system with 5 upper-level indicators and 12 basic-level indicators was proposed. Considering the independent and incompatible indicators, a comprehensive evaluation method of traffic safety of the visual guiding system in urban tunnels was constructed by using the extension matter-element model. Taking the scene of 4 types of tunnel curves, such as no facilities, horizontal stripe, chevron alignment sign, and LED arch, as examples, the comprehensive evaluation of various schemes were carried out by using simulation tests. RESULTS: The traffic safety comprehensive evaluation system of visual guiding system in urban tunnels can be analyzed from five aspects: perception reaction, guidance ability, driver factor, driving task, and facility appearance. The results demonstrated significant the comprehensive evaluation result of the target level of scene 1 was L4, scene 2 was L3, scene 3 was L2, and scene 4 was L1. That is, the final results of the comprehensive evaluation of the four scenes were poor, medium, good, and very good, respectively. CONCLUSIONS: In the scheme of visual guiding system for urban tunnel curves, the effectiveness of the three types of designs, from high to low, was the LED arch, chevron alignment sign, and horizontal stripe, and the safety of the scene without facilities was the lowest. Hence, setting the LED arch in the urban tunnel curve has a good effect in the aspects of guidance ability, sight distance, and sight zone, and is conducive to the driver's perception reaction and driving task.
RESUMO
Background/Objectives: Benign paroxysmal positional vertigo (BPPV) is the most common cause of recurrent vertigo and the most common peripheral vestibular disorder. It is characterized by intense vertigo triggered by head and position changes. This study investigates the risk of subsequent injury in BPPV patients and the effects of treatment. Methods: A population-based retrospective cohort study was conducted using data from the Longitudinal Health Insurance Database 2005 in Taiwan. Patients with and without BPPV were identified between 2000 and 2017. The study outcomes were diagnoses of all-cause injuries. The Kaplan-Meier method determined the cumulative incidence rates of injury in both cohorts, and a log-rank test analyzed the differences. Cox proportional hazard models calculated each cohort's 18-year hazard ratios (HRs). Results: We enrolled 50,675 patients with newly diagnosed BPPV and 202,700 matched individuals without BPPV. During follow-up, 47,636 patients were diagnosed with injuries (13,215 from the BPPV cohort and 34,421 from the non-BPPV cohort). The adjusted HR for injury in BPPV patients was 2.63 (95% CI, 2.49-2.88). Subgroup analysis showed an increased incidence of unintentional and intentional injuries in BPPV patients (aHR 2.86; 95% CI, 2.70-3.13 and 1.10; 95% CI, 1.04-1.21, respectively). A positive dose-response relationship was observed with increasing BPPV diagnoses. Treatment with canalith repositioning therapy (CRT) or medications reduced the risk of injury slightly but not significantly (aHR, 0.78; 95% CI, 0.37-1.29, 0.88; 95% CI, 0.40-1.40, respectively). Conclusions: BPPV is independently associated with an increased risk of injuries. CRT or medications have limited effects on mitigating this risk. Physicians should advise BPPV patients to take precautions to prevent injuries even after treatment.
RESUMO
OBJECTIVE: Traffic injuries significantly impact people's psychological, physical and social wellbeing, and involve complex self-regulation responses. Psychological impacts are seldom recognized and addressed holistically. This study employs network analysis to investigate the interconnectedness between different dimensions that influence mental health vulnerability and recovery after traffic injuries. METHODS: 120 adults with mild-to-moderate traffic injuries and 112 non-injured controls were recruited. The network investigation employed two main approaches. Four cross-sectional networks examined the interrelationships between self-regulation responses (cognitive and autonomic) and various health dimensions (psychological, physical, social) over time (1, 3, 6, 12 months). Three predictive networks explored influences of acute self-regulation responses (1 month) on long-term outcomes. Network analyses focused on between-group differences in overall connectivity and centrality measures (nodal strength). RESULTS: An overall measure of psychological wellbeing consistently emerged as the most central (strongest) node in both groups' networks. Injured individuals showed higher overall connectivity and differences in the centrality of self-regulation nodes compared to controls, at 1-month and 12-months post-injury. These patterns were similarly observed in the predictive networks, including differences in cognitive and autonomic self-regulation influences. CONCLUSIONS: Network analyses highlighted the crucial role of psychological health and self-regulation, in promoting optimal wellbeing and effective recovery. Post-traffic injury, increased connectivity indicated prolonged vulnerability for at least a year, underscoring the need of ongoing support beyond the initial improvements. A comprehensive approach that prioritizes psychological health and self-regulation through psychologically informed services, early psychological screening, and interventions promoting cognitive and autonomic self-regulation is crucial for mitigating morbidity and facilitating recovery.

BACKGROUND: Motorcycle crashes are an increasing public health problem in low- and middle-income countries (LMICs). An accurate estimation of the economic burden of these crashes could be complex owing to a prevalent system of out-of-pocket (OOP) payment for health care services in these countries. Our study aims to objectively evaluate the cost implication of motorcycle Road Traffic Injuries (RTIs) among road crash victims managed at a major trauma reference hospital in Nigeria. Two economic evaluation methods were used to accurately reflect the cost-of-care (C-o-C) of each victim as well as for cross-validation. METHOD: This is a prospective cohort study conducted between August 2020 and May 2021. All patients involved in motorcycle road traffic crashes presenting to the Emergency Department of the University College Hospital, Ibadan, Nigeria, were included in the study. For each patient, all medical expenses from the time of injury (T0) to 30 days after injury (T30) or Time to death (TD) - whichever occurred first, were valued in costs, and added (Activity-based costing or ABC), while also estimating overall cost-of-care (C-o-C) at T30 or TD, using the willingness-to-pay (WTP) method. Following the WHO definition, catastrophic expenditure was defined as expenditure > 25% of the patient's estimated annual household income. RESULTS: Of the 150 consecutively managed motorcycle crashes victims during the study period, 112 had complete data. The median monthly household income for the cohort was $121 with 75% of them earning less than $180. The median cost-of-care (C-o-C), by ABC, was $242 ($143 - 828). For individual care items, expenditure on surgical intervention(s) was the highest followed by prosthesis and implant procurement, and radiological investigations. On the other hand, the estimated medical cost was $2356 (IQR $938 - 6475) by WTP. Only 14% had health insurance coverage. The overall expenditure was catastrophic for 46% of the patients. Monthly household income of < $180 (AOR=9.2; 95% CI=2.6-32.8; p < 0.001), absence of health insurance coverage (AOR=10.7; 95% CI=1.1-101.6; p = 0.040), and prolonged hospital stay above 14 days (AOR=25.1; 95% CI=5.5 -115.1; p = 0.001) were predictors of catastrophic expenditure. There was a weak positive correlation between actual cost-of-care using the ABC method and WTP (r = 0.247; p = 0.102). CONCLUSION: The aggregate cost of motorcycle RTIs is catastrophic for nearly half of the victims attending the University College Hospital, Ibadan. The willingness-to-pay method, though less tedious is often less reliable in these settings owing to a prevalent OOP payment system. This study identified the need to implement effective financial protection mechanisms against the high OOP expenditure faced by motorcycle crash victims in LMICs.

BACKGROUND AND AIMS: Quantifying the health burden of alcohol has largely focused upon harm to drinkers, which is an underestimate. There is a growing literature on alcohol's harm to others (HTO), but it lacks the systematic transfer of HTO into a comparative risk assessment framework. This study calculated disability-adjusted life years (DALYs) for fetal alcohol spectrum disorder (FASD), interpersonal violence and traffic injury due to another's drinking. DESIGN: This study is a disease burden analysis, using modelling of DALYs for New Zealand in 2018. SETTING AND PARTICIPANTS: The study took place among the Aotearoa/New Zealand population in 2018. MEASUREMENTS: The involvement of others' drinking was obtained from prevalence, alcohol-attributable fraction studies and administrative data. Disability weights (DW) for FASD were adapted from fetal alcohol syndrome (FAS) weights using a Beta-Pert probability distribution; for interpersonal injury, DWs used hospital events linked with injury compensation; for traffic injury, DWs used hospital events. Populations were stratified by ethnicity, age group and gender. A descriptive comparison was made with a previous estimate of DALYs for drinkers. FINDINGS: In 2018, 78 277 healthy life years were lost in Aotearoa/New Zealand due to alcohol's HTO. The main contributor (90.3%) was FASD, then traffic crashes (6.3%) and interpersonal violence (3.4%). The indigenous population, Maori, was impacted at a higher rate (DALYs among Maori were 25 per 1000 population; among non-Maori 15 per 1000 population). The burden of HTO was greater than that to drinkers (DALYs HTO = 78 277; DALYs drinkers = 60 174). CONCLUSIONS: Disability from fetal alcohol spectrum disorder (FASD) appears to be a major contributor to alcohol's harm to others in Aotearoa/New Zealand. Taking FASD into account, the health burden of harm to others is larger than harm to the drinker in Aotearoa/New Zealand, and ethnicity differences show inequity in harm to others. Quantification of the burden of harm informs the value of implementing effective alcohol policies and should include the full range of harms.

BACKGROUND: Motorcycle is a popular and growing form of intracity transportation in many Nigerian cities owing mainly to poorly developed transport systems. It contributes significantly to road traffic injuries (RTIs), which are a leading cause of death and disabilities in low- and middle-income countries. There is a lack of information on the quality of care received and the treatment outcome in patients with motorcycle RTIs in Ibadan and many cities in Nigeria. This study evaluated the characteristics of motorcycle-related RTIs, the quality of care received, and the outcome of the patients managed in a trauma reference center in Ibadan, Nigeria. METHODS: This is a prospective cohort study. All patients involved in motorcycle road traffic crashes who presented to the emergency department of the University College Hospital, Ibadan, between August 2020 and May 2021, were included in the study. Data on patients' demographics, history of the crash, injuries sustained, definitive care, and the outcome of in-hospital care were obtained from patients (and/or their carers) and the medical records. RESULTS: A total of 156 patients were seen, out of which 74.4% were males. About 76.2% were less than 45 years with a mean age of 35.7 ± 16.3 years, and the peak age group was 18-44 years. About 37 (23.7%) patients were involved in motorcycle/motorcycle collisions, whereas 67 (42.9%) were involved in motorcycle/car collisions. Riders accounted for 59.6% (93), and although 62% (97) of the patients presented within six hours of the crash, only 10.9% (17) presented within one hour. About 48% received some form of prehospital care rendered by officials of the Federal Road Safety Corps, police officers, or passers-by, and none was attended by a dedicated emergency ambulance team. The head and the limbs were the most affected anatomical areas, while orthopedic and neurosurgical procedures were the most required emergency surgical interventions. About 66.7% were discharged home with only 21.2% of them fit to return to pre-trauma function at discharge, and the mortality rate was 17.3%. Patients who presented at 7-24 hours (AOR = 2.99; 95% CI = 1.04-8.62; p-value = 0.043) and >24 hours after the accident (AOR = 5.65; 95% CI = 1.64-19.53; p-value = 0.006) were 2.99 and 5.65 times, respectively, more likely to die from motorcycle-related accident compared to those who presented within the first six hours. CONCLUSION: This study identified the growing burden of disabilities and mortalities related to motorcycle RTIs. It highlights the lack of prehospital trauma care, which is a reflection of the deficiency of a national, regional, or jurisdictional trauma system and the critical need to develop a functional trauma system.
RESUMO
The increasing incidence of road traffic injuries (RTIs) has contributed to the disability and death of millions of people on both a national and global level. This retrospective study was conducted at King Fahad University Hospital (KFUH), Khobar, Saudi Arabia, and included all patients who presented at the emergency department due to road traffic accidents (RTAs) between January 1st, 2022, and December 31st, 2022. Patient data was retrieved from the health information system at KFUH. Descriptive and inferential analysis were performed with several variables analyzed using multivariate logistic regression and factorial ANOVA (MANOVA). During this period, 921 patients were treated at the hospital's emergency department. Of these, 611 (66.3%) were men and 310 (33.7%) were women. The most frequently affected age group was 16-25, representing 427 (46.4%) cases. Most patients were Saudi citizens (837, 90.9%). Among the patients, 19 (2.1%) required surgical treatment within 24 hours of the RTA, and 29 (3.1%) were admitted to the surgical intensive care unit (SICU). There were eight fatalities, representing 0.9% of the cases. January had the highest number of RTAs (12.7%). Moreover, 463 individuals (50.3%) had some form of injury, the most common type being lacerations and abrasions (n=228, 24.8%). Upper limb fractures were the most frequent type of fracture, occurring in 73 cases (7.9%). Being male (P=0.001), non-Saudi (P=0.014), and experiencing accidents during June and July (P=0.002) were associated with an increased prevalence of injury. Mortality had a statistically significant relationship with different patient age groups (P=0.014), patient citizenship (P=0.005), and length of hospital stay (P<0.001).

Objective@#To investigate the incidence of road traffic injuries among online deliverymen and its influencing factors, so as to provide insights into prevention of road traffic injuries.@*Methods@#Online deliverymen who were registered on a takeaway platform and delivered within Baotou City, Inner Mongolia Autonomous Region were recruited using a convenience sampling method, and demographic information, delivery work conditions and road traffic injury data were collected through questionnaire surveys from June to September, 2023. Factors affecting the incidence of road traffic injuries were identified by a multivariable logistic regression model.@*Results@#A total of 603 questionnaires were allocated, and 584 were valid, with an effective rate of 96.85%. There were 467 men (79.97%) and 117 women (20.03%), 200 participants at ages of 31-40 years (34.25%), 215 crowdsourcing deliverymen (36.82%) and 510 full-time (87.33%). The incidence of road traffic injuries in the past one year was 14.90%, and 59 injuries were mild (67.82%). The parts of injuries were mainly upper limbs (31.03%) and lower limbs (45.98%). Multivariable logistic regression analysis showed that online deliverymen who did not wear a helmet at work (OR=2.591, 95%CI: 1.354-4.958) and worked as a crowdsourcing deliverymen (OR=2.232, 95%CI: 1.041-4.786) had higher risks of road traffic injuries, while online deliverymen who worked part-time (OR=0.154, 95%CI: 0.034-0.706) had lower risks of road traffic injuries.@*Conclusions@#The incidence of road traffic injuries among online deliverymen is associated with post, type of work and wearing helmets or not. The traffic safety education and management should be strengthened among online deliverymen.
