Integrating visual and community environments in a motorcycle crash and casualty estimation.

Motorcycle crashes pose a serious problem because their probability of causing casualties is greater than that of passenger vehicle crashes. Therefore, accurately identifying the factors that influence motorcycle crashes is essential for enhancing traffic safety and public health. The aim of this study was to address three major research gaps: first, existing studies have relatively overlooked the built environment in relation to visual factors; second, existing crash prediction models have not fully reflected the differences in built environment characteristics between areas with frequent motorcycle crashes and areas with frequent casualties; and third, multidimensional analysis for variable selection is limited, and the interpretability of the models is insufficient. Therefore, this study proposes a comprehensive framework for motorcycle crash and casualty estimation. The framework uses a data cube model incorporating OLAP operations to provide deeper insights into crash influencing factors at different levels of abstraction. We also utilized the XGBoost model to predict motorcycle high crash spots and casualty risk and integrate visual factors extracted from Google Street View images and community-level urban environments into the model. SHAP techniques were used to analyze and interpret the global and local feature importance of the models. Our results revealed that the factors affecting areas with frequent motorcycle crashes and the factors that affect casualties differ. In particular, visual factors such as vegetation and the sky ratio are important for estimating casualties. We aim to provide practical guidelines for a safe environment for motorcycle crashes.

Descriptive analysis of road traffic crashes encountered by Tanzanian motorcycle taxi drivers trained in first aid.

Introduction: In Dar es Salaam, Tanzania, death from road traffic crashes (RTC) occurs at roughly double the global rate. In this study, we sought to understand the locations and types of vehicles involved in RTC in Dar es Salaam encountered by a cohort of motorcycle taxi drivers previously trained in first aid. Methods: This was a quasi-non-randomized interventional study, cohort subtype, with three-month follow-up. Some 186 motorcycle taxi drivers were selected by convenience sampling from 16 heavily populated, central wards and trained in a basic hemorrhage control course. Participants reported the location and types of vehicles involved in RTCs they encountered and intervened upon through performing bleeding control interventions. Surveys were designed on KoboToolbox and administered via phone call at monthly intervals over a three-month period. The main outcome measures were the location of crash encounters and types of vehicles involved. Results: In all 62 unique participants (33.3 %) encountered and provided bleeding control interventions to 83 injured individuals following 69 RTC in at least 31 distinct city wards, despite training only having occurred in 16 wards. Eight crash locations were not recorded. Crashes in distant wards typically contained major roads. Most commonly, crashes involved a motorcycle without the involvement of another vehicle (n=20), followed by motorcycle vs. car/three-wheeled vehicle (n=15), motorcycle vs. bus/van (n=10), motorcycle vs. motorcycle (n=9), motorcycle vs. pedestrian (n=7), pedestrian vs. bus/van (n=2), pedestrian vs. car/three-wheeled vehicle (n=1), motorcycle vs. bicycle (n=1), multi vehicle (n=1), and other (n=3). Conclusions: Motorcycle taxi drivers trained in hemorrhage control frequently encounter and intervene upon RTC in wards where they are based as well as in distant locations, commonly in wards containing major roads. Expanding first aid training for motorcycle taxi drivers could improve timely access to emergency care for RTC victims. Since most crashes involved motorcycles, road safety training should be integrated into future courses.

Friction Burns: Defining the Rub of Road Rash After Motorcycle Trauma.

There is a paucity of literature on friction burn epidemiology, injury characteristics, and management after trauma. This study aims to characterize friction burns resulting from motorcycle accidents, evaluate the role of specialized burn surgery teams, and assess the need for operative intervention. The trauma registry of a Level 1 Trauma Center was queried for all admissions after motorcycle accidents between January 2018 and December 2022. Patients were included if there was an external cause of injury code for an abrasion. Chart review was conducted to confirm a road rash injury, identify burn consultation, wound care recommendations, need for operating room (OR) procedure and skin grafting, and outcomes. Among the 810 patients meeting inclusion criteria, the cohort was 92% male, 46% Hispanic, with median age of 33 (IQR 26-44), and median ISS 8 (IQR 5-14). The extremities were most affected by friction burn followed by the abdomen, thorax, and face. Burn surgery was consulted in 7% (n=57) of cases which had a median TBSA of 4% (IQR 2-6%); 23% (n=13) of these patients underwent excision in the OR, 16% (n=9) required autografting, and 61% (n=35) were referred for burn follow-up on discharge. On multivariable regression, consults to burn were more likely in female patients (OR 3.40, p=0.002) and those with involvement of the upper extremity, abdomen, or thorax. Friction burns are common after motorcycle-related trauma. Local wound care is sufficient for a vast majority of these injuries and the need for specialized burn care and operative intervention is rare.

Exploring the barriers and underlying factors of utilizing a motorcycle without a license among adolescent boys: a qualitative study in Iran.

BACKGROUND: Motorcyclists constitute the highest proportion of victims of road traffic accidents. Riding a motorcycle without a license in teenagers is one of the accident-causing behaviors. Therefore, the current study was conducted with the aim of qualitatively investigating the obstacles and underlying factors of utilizing a motorcycle without a license among adolescent boys in Iran. METHODOLOGY: The present research qualitative research employed the grounded theory approach. The study population of the current research included all teenagers aged 10-18 years old in Farsan City of Chaharmahal and Bakhtiari province in 2023. The sample size was 14 obtained on the principle of data saturation using the purposeful sampling method. Interviews with participants using a semi-structured questionnaire were conducted. For data coding, MAXQDA 2022 software was used, and data analysis was done with open, axial, and selective coding methods. RESULTS: The lowest age at the first experience riding a motorcycle was 10 years old. Most of the cases had their first experience of riding a motorcycle at the age of 14 years. By achieving theoretical saturation in the interviews, 51 open codes were identified, and our qualitative data analyses resulted in 7 obstacles to unlicensed motorcycling in 4 categories. "Traffic rules and the desire to get a license", "accidents and financial, life and insurance losses", "the existence of a suitable structure for motorcycle riding training", and "opposition of families and unavailability of motorcycles". Also, regarding the 15 factors underlying driving a motorcycle without a license, 7 categories, "disregarding traffic rules", "inappropriate educational structure", "excitement and pleasant feeling", "spending life and free time", "enthusiasm and love" Youth", "Encouragement and support of significant others and availability of motorcycles", "Economic problems" were obtained. CONCLUSIONS: According to the findings, the obstacles and underlying factors of riding motorcycles without a license were identified from the perspective of teenagers, by focusing on these factors and also changing or modifying the things that can be changed, the occurrence of this behavior and ultimately the resulting injuries can be reduced.

A comparison of heat effects on road injury frequency between active travelers and motorized transportation users in six tropical and subtropical cities in Taiwan.

Road traffic injuries (RTIs) pose significant public health threats, particularly for vulnerable road users such as pedestrians and cyclists. While recent studies have revealed adverse impacts of heat exposure on RTI frequency among motorized road users, a research gap persists in understanding these impacts on non-motorized road users, especially in tropical regions where their vulnerability can be heightened due to differential thermal exposure, adaptive capacity, and biological sensitivity. In this study, we compared associations between high temperatures and RTIs across four different crash-involved modes of transportation-pedestrians, cyclists, motorcyclists, and car drivers in Taiwan. Leveraging data on RTI records and temperature conditions in Taiwan's six municipalities from 2018 to 2022, we conducted a city-time-stratified case-crossover analysis. We employed distributed lag non-linear models with conditional Poisson regression models to estimate temperature-RTI associations for each mode of transportation, adjusting for various weather factors and unmeasured spatio-temporal patterns. Our findings reveal that individuals using exposed, open transportation modes (i.e., pedestrians, cyclists, and motorcyclists) exhibited higher relative risks of heat-induced RTIs than car drivers, with non-motorized mode users showing greater susceptibility compared to their motorized counterparts. These elevated risks can be attributed to the absence of built-in cooling systems in open travel modes and the increased exertional heat stress implied in active travel. Our study contributes novel insights to a global concern related to climate change, extending its impact to road safety, a health outcome rarely studied in the context of a changing climate. Our findings are thus important, especially for regions where rising temperatures regularly approach or exceed human physiological limits related to heat tolerance in the coming decades. Additionally, our findings hold significance in the existing urban health literature, particularly within the context of the emerging era of micromobility-a category of low-speed, non-enclosed, and lightweight vehicles increasingly integrated into urban activities worldwide.

Exploring the experiences and challenges of motorcycle ambulance personnel in pre-hospital emergency healthcare services: A qualitative study.

BACKROUND: Motorcycle ambulances are particularly useful in navigating narrow and congested areas during premium hours due to their ability to provide rapid access to patients in pre-hospital emergency healthcare services (PHEHS), possessing suitable and necessary advanced life support accessories, and their speed, flexibility, and ease of maneuverability. OBJECTIVE: This study aims to examine the experiences and challenges encountered by motorcycle ambulance workers in PHEHS. METHODS: This study adopts a qualitative research methodology, specifically employing a phenomenological approach within the framework of a case study. The research sample consists of 19 paramedics and Emergency Medical Technicians (EMTs) working on motorcycle ambulances. Purposeful sampling method, specifically the snowball sampling technique, was employed in selecting the sample. Research data were collected through in-depth interviews conducted using a semi-structured interview form, from August 2022 to February 2023. The interviews were transcribed, coded, and thematically analyzed using the MAXQDA program. RESULTS: Participants shared their experiences and the problems they encountered while performing their duties across four themes: purpose of motorcycle ambulances, most frequently assigned cases, challenges encountered, and the importance of teamwork. CONCLUSIONS: It is crucial to ensure personnel safety by forming the motorcycle ambulance team from selected individuals, subjecting the selected personnel to the same standard and comprehensive advanced driving and technical training, regulating working hours, increasing the number of personnel, and fostering teamwork. Further efforts are needed to improve the working conditions of motorcycle ambulance services.

Not the same: How delivery, ride-hailing, and private riders' roles influence safety behavior.

In recent years, the growth of motorcycle-based ride-hailing and delivery services has led to an increase in traffic crashes involving these riders. Previous studies have indicated that the behavior of ride-hailing and delivery riders is influenced by work demands and individual characteristics. However, the extent to which risky riding behaviors depend on the type of riding and the interaction between road traffic context and risky behaviors remains unclear. Addressing these gaps, this study investigates factors influencing risky behaviors among motorcycle riders in Hanoi, Vietnam. By examining various rider traits (such as rider type, gender, and age) and aspects of the road traffic environment (such as police presence, number of road lanes, and weather), we aim to understand their contribution to risky riding behaviors. Through the observation of 9164 motorcycle riders (i.e., delivery, ride-hailing, and private motorcycle riders) at 31 intersections and decision tree analysis, the study underscores the significant impact of rider type on risky behaviors. Key findings include a higher tendency for both delivery riders and ride-hailing riders to run red lights, neglect to use turn signals, and the notable distraction of mobile phone use. Additionally, private riders are found to show a higher incidence of not wearing helmets even in locations with a police presence. These findings highlight the critical need for strategies to enhance road safety for all motorcycle riders. However, it is essential to recognize that the reasons behind risky behavior vary across different groups of motorcycle riders, from private to commercial riders. Therefore, we need more targeted strategies that address the specific factors influencing each group to effectively improve road safety for all.

Rural adolescent attitudes and use of helmets while riding ATVs, motorcycles and dirt bikes.

BACKGROUND: Head injuries are the most common cause of death in some motorized vehicles for which helmet use can significantly decrease the risk. Our objective was to determine rural adolescents' attitudes regarding helmets and their use while riding ATVs, motorcycles and dirt bikes. METHODS: A convenience sample of 2022 Iowa FFA (formerly Future Farmers of America) Leadership Conference attendees were surveyed. After compilation, data were imported into the statistical program, R ( https://www.R-project.org/ ). Descriptive statistics, contingency table, logistic regression and non-parametric alternatives to ANOVA analyses were performed. RESULTS: 1331 adolescents (13-18 years) participated. One half lived on a farm, 21% lived in the country/not on a farm and 28% were from towns. Nearly two-thirds (65%) owned an ATV with 77% of all having ridden one in the past year. Farm residents had the highest ATV ownership (78%) and having ridden (80%) proportions, both p < 0.001. Overall, ownership and ridership for motorcycles (22% and 30%, respectively) and dirt bikes (29% and 39%, respectively) was significantly less than ATVs, all p < 0.001. Of ATV riders, those living on farms or in the country/not on a farm rode them more frequently than those from towns, p < 0.001. Higher percentages always/mostly wore helmets when riding dirt bikes (51%) and motorcycles (57%) relative to ATVs (21%), p < 0.001. Those from farms had lower proportions wearing helmets versus those living elsewhere for all vehicles. Helmet use importance ratings (1-10, 10 high) were not different for motorcycles (mean 8.6, median 10) and dirt bikes (mean 8.3, median 10), but much lower for ATVs (mean 6.1, median 6). Females, non-owners, and helmet law supporters all had higher helmet use importance ratings. Males, those from farms, and owners and riders of the vehicles all had lower proportions that supported helmet laws. Support for helmet laws was significantly lower for ATVs (30.7%) than dirt bikes (56.3%) or motorcycles (72.3%), both p < 0.001. Those whose families had strict ATV "No Helmet, No Riding" rules had much higher helmet use and helmet importance ratings. CONCLUSIONS: Our study indicates that the safety culture surrounding helmet use is relatively poor among rural adolescents, especially on farms, and deserves targeted interventions.

Epidemiological analysis of the facial fractures pattern in relation to motorcycle helmet type: A retrospective study on 282 patients.

Most maxillofacial traumas are caused by road traffic collisions and, in particular, by motorcycle accidents. Helmets represent an efficient protective tool in these traumas but they do not provide complete protection. The aim of this study was to perform an epidemiological analysis of facial fractures pattern in relation to the helmet type worn during the accident. The study was a retrospective analysis of 282 patients with a diagnosis of maxillofacial fracture caused by a motorcycle accident. The patients were divided in three groups based on helmet type (Group A: full-face helmet; Group B: modular [half-face] helmet; Group C: open-face helmet). For each group, fractures type and trauma severity, using the Comprehensive Facial Injury (CFI) scale, were recorded. Results showed that isolated midface fractures were strongly related to full-face helmet wearing (p < 0.001), while mandibular fractures and panfacial trauma/combined fractures were negatively correlated (p < 0.001). Mandibular fractures (p < 0.001) and panfacial trauma/combined fractures (p < 0.001) were strongly related to open helmet. Moreover, severe trauma (CFI 8.16) was recorded for open-face helmet wearing. In conclusion, full-face helmet wearing reduced the risk of facial fracture, in particular panfacial trauma/combined fractures, while open-face helmet wearing increased the risk of these fractures.

Road traffic safety for older adults: an emerging public health challenge in Thailand.

BACKGROUND: Road safety for older adults should receive more attention in low-income and middle-income countries with rapidly ageing populations. METHODS: Using injury surveillance data from Khon Kaen Regional Hospital in northeastern Thailand, we calculated the proportion of older adults in the total number of patients who were fatally and non-fatally injured in road traffic crashes in each year from 2001 to 2020 and the proportion of road user type in the fatal and non-fatal patients by age groups for the entire study period to examine the extent to which older adults were involved in the crashes and with what mode of transportation. RESULTS: During the 20-year period, there were 5046 fatal and 180 353 non-fatal patients of whom 509 (10%) and 6087 (3%) were aged 65 years or older, respectively. From 2001 to 2020, this proportion increased from 3% to 20% among the fatal patients and from 1% to 6% among the non-fatal patients. Of the fatal and non-fatal patients aged 65 years or older, 50% and 54% were involved in road traffic crashes while driving motorcycles and 28% and 22% while riding bicycles or walking, respectively. Compared with patients aged 65-74 years, those aged 75 years or older tended to be bicyclists or pedestrians in the crashes, though as high as 40% of them were motorcycle drivers. CONCLUSION: Older adults are increasingly injured in road traffic crashes as vulnerable road users in Thailand. Therefore, road safety efforts should consider their presence on the road.

Isolated musculocutaneous nerve injury in a motorcyclist - a case report.

INTRODUCTION: Isolated musculocutaneous nerve injuries occur rarely due to their anatomical location. We present our patient with a musculocutaneous nerve injury in a motorcyclist. CASE: The patient was initially treated for a motorcycle accident. Further examination of the patient revealed impaired elbow flexion and numbness of the lateral forearm. Electromyography confirmed impaired function of the musculocutaneous nerve. After 3 months, the patient's condition did not show any improvement, neither electromyography confirmed recovery of the nerve activity, so surgical treatment was planned. In the surgical revision, neuroma-in-continuity was discovered and resected. The resulting nerve defect was 6 cm long. We provided nerve grafting using sural nerve from the right lower limb. After surgery, the patient began physical therapy and electrical stimulation. Two years later, the patient reached complete recovery of muscle strength. CONCLUSION: Due to the lack of improvement after a 3-month period, we proceeded with a surgical revision, which demonstrated a complete lesion of the nerve that could not heal spontaneously. Therefore, we opted for the nerve graft method and the patient regained full function of elbow flexors.

Profile of Mortal Injuries in Vehicular Accidents: An Autopsy-Based Study.

Background It is crucial to analyze the trends of fatal injuries among pedestrians, passengers, motorcycle riders, and drivers of three- and four-wheelers in traffic accidents. Objective To ascertain the trend of fatal injuries to the head, chest, and abdomen across different victim categories in vehicular accidents. Materials and methods An autopsy-based prospective study was carried out in the mortuary of a rural tertiary care hospital. A total of 108 fatal cases of vehicular accidents were taken into consideration. All natural and unnatural deaths, other than those stemming from vehicle crashes, were excluded from this study; only the victims of fatal vehicular accidents were included. Results Males outnumbered female victims by 8.8:1. The age range of 41-60 years was the most affected (38.9%). The greatest number of victims (17, or 15.8%) were male motorcycle riders in the range of 21-40 years. Most vehicular mishaps (61; 56.5%) occurred during the evening. The most frequent injury pattern reported was head injuries (53.4%). Conclusions Motorcycle riders constituted the most severely injured victim category in a vehicular accident. Most mishaps occurred in the dark because of inadequate lighting or bad road conditions in rural areas. Furthermore, the most frequently occurring type of injury was an injury to the head, which may be an outcome of riders' lack of compliance with the mandatory helmet-use policy.

Quantifying rider posture variability in powered two- and three-wheelers for safety assessment.

OBJECTIVE: Injury outcomes for powered two- and three-wheeler (PTW) riders are influenced by the rider posture. To enable analysis of PTW rider accidents and development of protection systems, detailed whole-body posture data is needed. Therefore, the aim of this study is to fill this gap by providing collections of average male whole-body postures, including subpopulation variability, for different PTW types. This will enable future studies to explore the influence of PTW rider posture variation and to support safety system development. METHODS: 3D photometric measurements of 51 anatomical landmarks were recorded on 20 (50th percentile male) volunteers in their preferred riding postures across three PTW types (naked, scooter, and touring). Following an outlier removal process, a principal component analysis (PCA) was performed to calculate average postures and principal components (PCs), to describe the observed posture variation, for each PTW. The visualization of the PCs was facilitated through kinematic linkage representations, connecting anatomical landmarks and estimated joint centers to form segments and characteristic joint angles. RESULTS: The first seven PCs explained 80% of the variance in posture for each of the three PTWs. Across PTWs, these PCs frequently described combinations of postural features including variation in fore-aft seat positions, pelvic tilt, spinal curvature, head position, and extremity flexion-extension. Analysis revealed distinct differences in average postures across the three PTWs, on average, 10 ± 9° for the characteristic joint angles within a min-to-max range between the three PTWs. However, for all three PTWs, the variability between volunteers in characteristic joint angles on the same PTW were on average more than twice as large within a ± 2 SD range (26 ± 11°). CONCLUSIONS: The results suggest that PTW rider posture variation must be addressed by involving simultaneous adjustments of multiple body parts, as described by each of the first seven PCs, as a direct consequence of the human body interconnectedness. Furthermore, the study's findings challenge conventional assumptions that the relative distance between PTWs' handlebar, seat, and foot support predominantly influences rider postures. Instead, the research demonstrates that individual variability has a substantial influence on rider posture and should be considered in PTW safety development.

Replication of a local record keeping method for collecting road crash data in low resource settings: lessons from Bangladesh and Nepal.

BACKGROUND: Police road crash and injury data in low-income and middle-income countries are known to under-report crashes, fatalities and injuries, especially for vulnerable road users. Local record keepers, who are members of the public, can be engaged to provide an additional source of crash and injury data. METHODS: This paper compares the application of a local record keeper method to capture road crash and injury data in Bangladesh and Nepal, assesses the quality of the data collected and evaluates the replicability and value of the methodology using a framework developed to evaluate the impact of being a local record keeper. OUTCOME: Application in research studies in both Bangladesh and Nepal found the local record keeper methodology provided high-quality and complete data compared with local police records. The methodology was flexible enough to adapt to project and context differences. The evaluation framework enabled the identification of the challenges and unexpected benefits realised in each study. This led to the development of an 11-step process for conducting road crash data collection using local record keepers, which is presented to facilitate replication in other settings. CONCLUSION: Data collected by local record keepers are a flexible and replicable method to understand the strengths and limitations of existing police data, adding to the evidence base and informing local and national decision-making. The method may create additional benefits for data collectors and communities, help design and assess road safety interventions and support advocacy for improved routine police data.

Project PRIME: road markings for motorcycle casualty reduction (an overview of findings from 2020 to 2022).

Pioneering road markings for motorcyclists, designed as Perceptual Rider Information for Maximising Expertise and Enjoyment (PRIMEs) were installed on approach to demanding bends at 22 trial sites and two comparison sites across the West Highlands of Scotland. The markings provided a series of 'gateways' to encourage safer riding. With 32,213 motorcyclists observed, the following statistically significant results were observed: speed reductions at 10 trial sites; positive changes in lateral position at the final PRIME gateway marking at 15 trial sites and positive changes in lateral position at the apex of the bend at 13 trial sites; reductions in braking at nine trial sites; increases use of PRIME road markings across 18 of the 22 trial sites. No statistically significant effects were observed at the comparison sites. These findings are discussed in relation to the 'Road Safety Framework to 2030' and the 'Safe System' approach to reducing motorcycle casualties.

This world-first research presents the largest investigation of rider behaviour involving 32,213 motorcyclists. Pioneering road markings for motorcyclists produced statistically significant positive behavioural changes in speed, lateral lane position and braking. This work identifies important behavioural factors that support the 'Safe System' approach to motorcycle casualty reduction.

Supervised and unsupervised techniques to analyze risk factors associated with motorcycle crash.

PURPOSE: Motorcycles are one of the highly used modes of transport in Barcelona, Spain, in particular, and in many different regions, in general. This situation is compromising safety on the road and may be attributed to a potential increase in traffic crashes. Therefore, this study examines several risk factors and their consequential impacts on the level of injury that is resulted in case of a traffic crash. METHODS: Two approaches are employed to analyze the risk factors, including a supervised learning technique which is a binary probit model, and an unsupervised technique which is the Kohonen clustering. RESULTS: The results for both models show that alcoholism and road in poor condition can indeed increase the probability of having different levels of injuries as reasons for the crash. Elderly users are less likely to be involved in motorcycle crash injuries compared to other age categories, especially the age group that ranges from 25 to 40 years old which has the highest odds. For both techniques, the performance in analyzing the utilized data shows that both approaches can be successfully utilized for this type of dataset. CONCLUSION: This study highlights the considerable danger faced by motorcyclists due to various risk factors. It stresses the critical importance of maintaining roads in optimal condition not just for efficient travel but also to enhance motorcyclists' safety. Additionally, the research underscores the significant threat posed by speeding, particularly exceeding speed limits, to motorcyclists' safety, emphasizing the urgent need for more 30 km/h speed limit zones and stricter enforcement of speed regulations. As a result, the research has identified several risk factors that increase the likelihood of severe or fatal injuries among motorcyclists in Barcelona and has suggested certain recommendations to mitigate their impact.

Bivariate ordered probit modelling of motorcycle riders and pillion passengers' injury severities relationship and associated risk factors.

This study simultaneously modelled the injury severity of motorcycle riders and their pillion passengers and determine the associated risk factors. The analysis is based on motorcycle crashes data in Ashanti region of Ghana spanning from 2017 to 2019. The study implemented bivariate ordered probit model to identify the possible risk factors under the premise that the injury severity of pillion passenger is endogenously related to that of the rider in the event of crash. The model provides more efficient estimates by considered the common unobserved factors shared between rider and pillion passenger. The result shows a significant positive relationship between the two injury severities with a correlation coefficient of 0.63. Thus, the unobservable factors that increase the probability of the rider to sustain more severe injury in the event of crash also increase that of their corresponding pillion passenger. The rider and their pillion passenger injury severities have different propensity to some of the risk factors including passengers' gender, day of week, road width and light condition. In addition, the study found that time of day, weather condition, collision type, and number of vehicles involved in the crash jointly influence the injury severity of both rider and pillion passenger significantly.

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. TRIAL REGISTRATION: Pan African Clinical Trials Registry (PACTR202308851460352); https://pactr.samrc.ac.za/TrialDisplay.aspx?TrialID=25763.

Motorcycle injuries: a systematic review for forensic evaluation.

The intricate interplay of exposure and speed leave motorcyclists vulnerable, leading to high mortality rates. During the collision, the driver and the passenger are usually projected away from the motorcycle, with variable trajectories or final positions. Injuries resulting from the crash can exhibit distinct and specific characteristics depending on the circumstances of the occurrence.The aim of this study is to provide a systematic review of the literature on injuries sustained by motorcyclists involved in road accidents describing and analyzing elements that are useful for forensic assessment.The literature search was performed using PubMed, Scopus and Web of Science from January 1970 to June 2023. Eligible studies have investigated issues of interest to forensic medicine about during traffic accidents involving motorcycle. A total of 142 studies met the inclusion criteria and were classified and analyzed based on the anatomical regions of the body affected (head, neck, thoraco-abdominal, pelvis, and limb injuries). Moreover, also the strategies for preventing lesions and assessing injuries in the reconstruction of motorcycle accidents were examined and discussed.This review highlights that, beyond injuries commonly associated with motorcycle accidents, such as head injuries, there are also unique lesions linked to the specific dynamics of accidents. These include factors like the seating position of the passenger or impact with the helmet or motorbike components. The forensic assessment of injury distribution could serve as support in reconstructing the sequence of events leading to the crash and defining the cause of death in trauma fatalities.

Opportunities and challenges on hospital preparedness to handle motorcycle accidents in Busia County, Kenya: an exploratory qualitative study.

Introduction: motorcycles continue to be a popular mode of transport in Kenya. However, the related injuries cause significant morbidity and mortality and remain to be a major and neglected public health issue. This raised the crucial need for hospital preparedness in managing morbidities and in reducing mortalities. This formed the basis of this paper which aims to document the challenges and opportunities in the healthcare system in handling motorcycle accidents in a Kenyan border town in Busia County. Methods: we drew data from an exploratory qualitative study that was carried out in 2021. All six referral hospitals purposively included in the study. The study targeted a total of 25 top level facility managers as key informants on the facility level opportunities and challenges in handling motorcycle accidents. Descriptive data were analyzed using SPSS version 20. Results: the hospitals were not well prepared to handle motorcycle accidents. The major challenges were understaffing in critical care services; inadequate/lack of equipment to handle motorcycle injuries; inadequate/lack of infrastructure i.e. surgical wards, emergency rooms, inadequate space, functional theatre; lack/inadequate supplies; overstretched referral services arising from the hinge burden of motorcycle accidents in the area; inadequate specialized personnel to provide trauma/care services; mishandling of cases at the site of accident; inability of victims to pay related bills; inappropriate identification of victims at the facility; lack/inadequate on-job training. Some opportunities that currently exist include health system interventions which are not limited to employment of more professionals, improvement of infrastructure, provision of equipment and increase of budgetary allocation. Conclusion: the study reveals vast challenges that are faced by hospitals in managing patients. This calls for the government to step in and capitalize on the proposed opportunities by the health managers to be able to manage morbidities and bring down mortalities due to motorcycle accidents.
