The burden of road traffic crashes, injuries and deaths in Africa: a systematic review and meta-analysis

Trauma care and its financing around the world

ABSTRACT

Worldwide, one billion people sustain trauma, and 5 million people will die every year from their injuries. Countries must build trauma systems to effectively address this high-burden disease, but efforts are often challenged by financial constraints. Understanding mechanisms for trauma funding internationally can help to identify opportunities to address the burden of injuries. Trauma leaders from around the world contributed summaries around how trauma is managed across their respective continents. These were aggregated to create a comparison of worldwide trauma systems of care. The burden of injuries is high across the world's inhabited continents, but trauma systems remain underfunded worldwide and, as a result, are overall underdeveloped and do not rise to the levels required given the burden of disease. Some countries in Africa and Asia have invested in financing mechanisms such as road accident funds or trauma-specific funding. In Latin America, active surgeon involvement in accident prevention advocacy has made meaningful impact. All continents show progress in trauma system maturation. This article describes how different regions of the world organize and commit to trauma care financially. Overall, while trauma tends to be underfunded, there is evidence of change in many regions and good examples of what can happen when a country invests in building trauma systems.

A needs assessment for formal emergency medicine curriculum and training in Zambia

Emergency medicine (EM) is a nascent field in Zambia. While not yet recognized as a medical specialty, there is national interest for developing more robust emergency care systems in this setting. One key element of strengthening EM in Zambia is identifying current gaps in emergency healthcare provision and opportunities for advancement in the field. This research used a modified version of the Emergency Care Assessment Tool to characterize the landscape of EM in Zambia. We collected data on the extent of EM training and teaching engagement among physicians practicing EM in Zambia. The survey assessed three aspects of core EM "signal functions" among the respondents which included; how often they performed the function, how confident they felt with the function, and how important they deemed the function to be in their practice. Finally, we asked respondents to identify barriers to performing the functions in their departments. The majority of respondents were early in their career, all below the age of 50, and participated in some form of teaching and supervision of learners, with minimal access to teaching resources to enhance their work. There was unanimous agreement with the need for formal postgraduate EM training in Zambia. The EM functions performed least often by EM physicians, and in which they felt the least confident, were high-acuity low-occurrence (HALO) procedures such as surgical airway and pericardiocentesis. The most common barrier to performing an EM function was access to supplies, equipment and medication. The second most commonly cited barrier was healthcare worker training. This research identified several critical needs for EM curricula in Zambia, specifically teaching resources for clinicians who supervise learners, directed learning on HALO procedures, and formal postgraduate training in EM based in Zambia.

Epidemiology of orthopedic injuries among inpatients admitted at a tertiary teaching and referral hospital in Kenya: a retrospective cross-sectional study

BACKGROUND

Orthopedic injuries are serious and continue to be a concern for healthcare systems worldwide. Approximately 90% of the estimated traumatic injuries occur in low- and middle-income countries. In Kenya, there is a dearth of information on orthopedic injury patterns that could be used to prioritize injury prevention measures and to help hospital management teams allocate resources appropriately. The purpose of this study was to determine the epidemiology of orthopedic injuries admitted to Kenyatta National Hospital.

METHODS

This was a retrospective cross-sectional study. Overall, 720 charts were reviewed. Data were analyzed using frequency distribution, pearson chi-square test and logistic regression.

RESULTS

Overall, 85% were aged 15-64 years. Approximately 80% were male, married or single. Patients with primary or secondary education composed 72%. Road traffic accidents (59.4%) and falls (24.7%) were the most common mechanisms of injury. A total of 99.9% of the inpatients were Kenyans. Open injuries were 40.1%. Lower limb (67.4%) and upper limb (26.9%) injuries were the most common. Inpatients aged 15-24 years were 74% less likely to have upper limb injuries than those aged 0-14 years (p = 0.023). However, those aged 15-24 years were 19.250 times more likely to have spine injuries than those aged 0-14 years (p = 0.008). Males were 68.6% and 51.2% less likely to have pelvic injury and comorbidities, respectively, than females (p < 0.001). Patients with secondary and tertiary education were 2.016 (p = 0.003) and 2.3 (p < 0.001) times more likely to have upper limb injuries, respectively, than those with no or preschool education. Similarly, those with tertiary education were 2.079 times more likely to have comorbidities than those with no or preschool education (p = 0.017).

CONCLUSION

Most of the inpatients with orthopedic injuries were young, male involved in Road traffic accidents and therefore Kenya National Transport and Safety Authority needs to enforce road safety measures to reduce road carnage. Those with higher education and children were more likely to have upper limb injuries. Females were more likely to have pelvic injuries and co-morbidities. Lower and upper limb injuries were the most common injuries and this should guide resource allocation in management of orthopedic injuries.

Factors influencing nurses' pain assessment and management of road traffic casualties: a qualitative study at a military hospital in Ghana

BACKGROUND

Evidence shows that patients who visit the surgical and trauma emergency units may be discharged with untreated or increased pain levels. This study explored nurses' pain assessment and management approaches at a trauma-surgical emergency unit in Ghana.

METHODS

Seventeen nurses who work in the trauma department participated in this qualitative exploratory descriptive study. In-depth individual interviews were conducted, and the thematic analysis was utilized to identify emerging themes and subthemes.

RESULTS

Three main themes were identified: patient pain indicators, pain management, and institutional factors influencing pain management. The study revealed that nurses rely on verbal expressions, non-verbal cues, physiological changes, and the severity of pain communicated. The findings highlighted staff shortage, inadequate resources, and lack of standardized guidelines as factors affecting pain and management.

CONCLUSIONS

Although the study offers critical new perspectives on nurses' experiences regarding pain related issues at the trauma-surgical emergency units, its small sample size limited its generalizability.

Factors influencing the road accidents in low and middle-income countries: a systematic literature review

This paper studies the main factors affecting road traffic accidents (RTAs) using a systematic review. The primary focus is on factors related to road characteristics and driver behaviours. This review also addresses the socioeconomic and demographic factors to provide a clear overview of which groups suffer the most from RTAs. Several factors were found to affect RTAs, notably road characteristics: highways, high-speed roads, unplanned intersections and two-way roads without dividers; driver behaviours: reckless/aggressive driving and riding, excessive speeding, unawareness of traffic laws, and not using safety equipment; and vehicle types: four and two-wheeled. This review found that male and economically productive people with less education were mostly associated with RTAs. In addition, for most of the low and middle-income countries analyzed, there is a lack of quality data relating to RTAs. Nevertheless, this review provides researchers and policy makers with a better understanding of road accidents for improving road safety.

Effectiveness of road safety interventions: An evidence and gap map

Background

Road Traffic injuries (RTI) are among the top ten leading causes of death in the world resulting in 1.35 million deaths every year, about 93% of which occur in low- and middle-income countries (LMICs). Despite several global resolutions to reduce traffic injuries, they have continued to grow in many countries. Many high-income countries have successfully reduced RTI by using a public health approach and implementing evidence-based interventions. As many LMICs develop their highway infrastructure, adopting a similar scientific approach towards road safety is crucial. The evidence also needs to be evaluated to assess external validity because measures that have worked in high-income countries may not translate equally well to other contexts. An evidence gap map for RTI is the first step towards understanding what evidence is available, from where, and the key gaps in knowledge.

Objectives

The objective of this evidence gap map (EGM) is to identify existing evidence from all effectiveness studies and systematic reviews related to road safety interventions. In addition, the EGM identifies gaps in evidence where new primary studies and systematic reviews could add value. This will help direct future research and discussions based on systematic evidence towards the approaches and interventions which are most effective in the road safety sector. This could enable the generation of evidence for informing policy at global, regional or national levels.

Search Methods

The EGM includes systematic reviews and impact evaluations assessing the effect of interventions for RTI reported in academic databases, organization websites, and grey literature sources. The studies were searched up to December 2019.

Selection Criteria

The interventions were divided into five broad categories: (a) human factors (e.g., enforcement or road user education), (b) road design, infrastructure and traffic control, (c) legal and institutional framework, (d) post-crash pre-hospital care, and (e) vehicle factors (except car design for occupant protection) and protective devices. Included studies reported two primary outcomes: fatal crashes and non-fatal injury crashes; and four intermediate outcomes: change in use of seat belts, change in use of helmets, change in speed, and change in alcohol/drug use. Studies were excluded if they did not report injury or fatality as one of the outcomes.

Data Collection and Analysis

The EGM is presented in the form of a matrix with two primary dimensions: interventions (rows) and outcomes (columns). Additional dimensions are country income groups, region, quality level for systematic reviews, type of study design used (e.g., case-control), type of road user studied (e.g., pedestrian, cyclists), age groups, and road type. The EGM is available online where the matrix of interventions and outcomes can be filtered by one or more dimensions. The webpage includes a bibliography of the selected studies and titles and abstracts available for preview. Quality appraisal for systematic reviews was conducted using a critical appraisal tool for systematic reviews, AMSTAR 2.

Main Results

The EGM identified 1859 studies of which 322 were systematic reviews, 7 were protocol studies and 1530 were impact evaluations. Some studies included more than one intervention, outcome, study method, or study region. The studies were distributed among intervention categories as: human factors (n = 771), road design, infrastructure and traffic control (n = 661), legal and institutional framework (n = 424), post-crash pre-hospital care (n = 118) and vehicle factors and protective devices (n = 111). Fatal crashes as outcomes were reported in 1414 records and non-fatal injury crashes in 1252 records. Among the four intermediate outcomes, speed was most commonly reported (n = 298) followed by alcohol (n = 206), use of seatbelts (n = 167), and use of helmets (n = 66). Ninety-six percent of the studies were reported from high-income countries (HIC), 4.5% from upper-middle-income countries, and only 1.4% from lower-middle and low-income countries. There were 25 systematic reviews of high quality, 4 of moderate quality, and 293 of low quality.

Authors' Conclusions

The EGM shows that the distribution of available road safety evidence is skewed across the world. A vast majority of the literature is from HICs. In contrast, only a small fraction of the literature reports on the many LMICs that are fast expanding their road infrastructure, experiencing rapid changes in traffic patterns, and witnessing growth in road injuries. This bias in literature explains why many interventions that are of high importance in the context of LMICs remain poorly studied. Besides, many interventions that have been tested only in HICs may not work equally effectively in LMICs. Another important finding was that a large majority of systematic reviews are of low quality. The scarcity of evidence on many important interventions and lack of good quality evidence-synthesis have significant implications for future road safety research and practice in LMICs. The EGM presented here will help identify priority areas for researchers, while directing practitioners and policy makers towards proven interventions.

Prevalence and levels of disability post road traffic orthopaedic injuries in Rwanda

Background

Prolonged disability resulting from road traffic injuries (RTIs) contributes significantly to morbidity and disease burden. A good understanding of the prevalence and the level of disability of orthopaedic injuries in developing countries is crucial for improvement; however, such data are currently lacking in Rwanda.

Objectives

To determine the prevalence and levels of disability of 2 years post-road traffic orthopaedic injuries in Rwanda.

Method

A multicentre, cross-sectional study from five Rwandan referral hospitals of 368 adult RTI victims' sustained from accidents in 2019. Between 02 June 2022, and 31 August 2022, two years after the injury, participants completed the World Health Organization Disability Assessment Schedule (WHODAS 2.0) Questionnaire for the degree of impairment and the Upper Extremity Functional Scale and Lower-Extremity Functional Scale forms for limb functional evaluation. Descriptive, inferential statistics Chi-square and multinomial regression models were analysed using R Studio.

Results

The study's mean age of the RTOI victims was 37.5 (±11.26) years, with a sex ratio M: F:3: 1. The prevalence of disability following road traffic orthopedic injury (RTOI) after 2 years was 36.14%, with victims having WHODAS score > 25.0% and 36.31% were still unable to return to their usual activities. Age group, Severe Kampala Trauma Score and lack of rehabilitation contributed to disability. The most affected WHODAS domains were participation in society (33%) and life activities (28%).

Conclusion

The prevalence and levels of disability because of RTOI in Rwanda are high, with mobility and participation in life being more affected than other WHODAS domains. Middle-aged and socio-economically underprivileged persons are the most affected.

Contribution

This study showed that a good rehabilitation approach and economic support for the RTI victims would decrease their disabilities in Rwanda.

In-service education in trauma care for intensive care unit nurses: An exploratory multiple case study

AIM

This study explores the perceptions of intensive care units (ICUs) nurses with different educational backgrounds regarding their abilities in trauma care and the in-service education they receive to support it.

BACKGROUND

The advanced care of patients with traumatic injuries in ICU environments requires skilled and knowledgeable nurses, who need continuing and in-service education to provide the best care. Therefore, it is essential to understand the competencies and educational support these nurses may need in the ICUs to ensure safe and effective care delivery.

DESIGN

An exploratory multiple case study design was used, comprising three hospitals located in two different regions of Saudi Arabia.

METHODS

The study was conducted between October 2021 and March 2022. A total of forty ICU clinical staff, twelve managers, nine leaders and seven clinical educators participated in semi-structured interviews, which were complemented by a review of available documents on the trauma care in-service education syllabi, competencies and protocols. Interview data were analysed according to the Framework analysis approach, while documents were reviewed using qualitative content analysis.

FINDINGS

The data analysis revealed two interrelated categories relevant to trauma care: (i) care practice and (ii) education practice. The trauma care practice category highlighted the limited competencies and education in trauma care, as well as the perceived challenges and educational needs of nurses. The education practice category described the staff learning behaviours, supervision practices and in-service education systems in the participants' settings.

CONCLUSIONS

The study concludes that there is a lack of trauma care education at the examined sites. It suggests the need for further research to develop a theoretical foundation for trauma care education that can meet ICU nurses' educational needs while this being feasible to implement in the specific ICU context and practice.

Risk of permanent medical impairment after road traffic crashes: A systematic review

PURPOSE

To systematically review the risk of permanent disability related to road traffic injuries (RTIs) and to determine the implications for future research regarding permanent impairment following road traffic crashes.

METHODS

We conducted this systematic review according to the preferred reporting items for systematic reviews and meta-analysis statement. An extended search of the literature was carried out in 4 major electronic databases for scientific research papers published from January 1980 to February 2020. Two teams include 2 reviewers each, screened independently the titles/abstracts, and after that, reviewed the full text of the included studies. The quality of the studies was assessed using the strengthening the reporting of observational studies in epidemiology (STROBE) checklist. A third reviewer was assessed any discrepancy and all data of included studies were extracted. Finally, the data were systematically analyzed, and the related data were interpreted.

RESULTS

Five out of 16 studies were evaluated as high-quality according to the STROBE checklist. Fifteen studies ranked the initial injuries according to the abbreviated injury scale 2005. Five studies reported the total risk of permanent medical impairment following RTIs which varied from 2% to 23% for car occupants and 2.8% to 46% for cyclists. Seven studies reported the risk of permanent medical impairment of the different body regions. Eleven studies stated the most common body region to develop permanent impairment, of which 6 studies demonstrated that injuries of the cervical spine and neck were at the highest risk of becoming permanent injured.

CONCLUSION

The finding of this review revealed the necessity of providing a globally validated method to evaluate permanent medical impairment following RTIs across the world. This would facilitate decision-making about traffic injuries and efficient management to reduce the financial and psychological burdens for individuals and communities.

Out of hospital emergency care in Nigeria: A narrative review

Introduction

Out of Hospital Emergency Care (OHEC) in Nigeria, the most populous country with the highest GDP in Africa, is considered inadequate. A better understanding of the current state of OHEC is essential to address the country's unique challenges and offer potential solutions.

Objectives

This paper sought to identify gaps, barriers, and facilitators in implementing an OHEC model in Nigeria and provide recommendations for improvement.

Methods

We searched MEDLINE (PubMed), Embase (OVID), CINAHL (EBSCO), and Google Scholar, using combinations of "emergency medical care" ('FRC,' 'PHC,' and 'EMS') OR prehospital care OR emergency training' AND 'Nigeria.' We included papers that described OHEC in Nigeria and were published in English. Of the initial 73 papers, those that met our inclusion criteria and those obtained after examination of reference lists comprised the 20 papers that contributed to our final review. Two authors independently reviewed all the papers, extracted data relevant to our objectives and performed a content analysis. All authors reviewed, discussed, and refined the proposed recommendations.

Key recommendations

For OHEC to meet the needs of Nigerians and achieve international standards, the following challenges need to be addressed: harmful cultural practices, inadequate training of citizens in the provision of first aid or of professionals that provide prehospital care, lack of proper infrastructure, poor communication, absent policy, and poor funding. Based on the available literature, this paper proposes key recommendations to improve OHEC with the hope of improving the standards of living. The federal government should provide general oversight, but this will require political will on the part of the country's leadership and the provision of adequate funding.

Mortality Rate and Years of Life Lost Due to Road Traffic Accidents in Fars Province, 2004-2019

Background

Traffic accidents are one of the most critical health problems and the ninth leading cause of death globally. We aimed to determine the Mortality rate and the number of Years of Life Lost (YLL) due to road traffic accidents.

Methods

In this retrospective cohort study, mortality rate and YLL due to road traffic accidents were examined in Fars province, central Iran during the years 2004-2019. Mortality statistics were collected through death registration of ministry of health and medical education for Fars Province. Age Standardized mortality Rate (ASR) was calculated and join point regression analysis carried out to examine the trend of YLL rate. Data were analyzed using Excel spreadsheet version 2016 and Join point Regression Program 4.9.0.0.

Results

During the 16-year study period, 25,858 deaths due to road traffic accidents occurred in the province. 79.2% (20483 cases) were in men, and 33.7% (8703 cases) were aged 15-29 years. Total YLL during the 16-year study period were 458,975 (14.6 per 1000 people) in men, 117,999 (3.8 per 1000 people) in women. According to the join point regression, the 16- year trend of YLL rate due to premature mortality was decreasing: AAPC was -4.9% (95% CI: -8.8 to -0.9; P=0.018) for male, and -3.5% (95% CI: -6.3 to-0.5; P=0.011) for female.

Conclusion

Considering that the number of deaths, mortality rate and YLL has decreased in Fars province during the 16 years under study. Therefore, because the mortality rate due to road traffic accidents in Iran is higher than the global average, the need for training programs for drivers, compliance with standards and retrofitting of vehicles, road safety, driving supervision and the use of seat belts are essential.

The CBS test: Development, evaluation & cross-validation of a community-based injury severity scoring system in Cameroon

Injury-related deaths overwhelmingly occur in low and middle-income countries (LMICs). Community-based injury surveillance is essential to accurately capture trauma epidemiology in LMICs, where one-third of injured individuals never present to formal care. However, community-based studies are constrained by the lack of a validated surrogate injury severity metric. The primary objective of this bipartite study was to cross-validate a novel community-based injury severity (CBS) scoring system with previously-validated injury severity metrics using multi-center trauma registry data. A set of targeted questions to ascertain injury severity in non-medical settings-the CBS test-was iteratively developed with Cameroonian physicians and laypeople. The CBS test was first evaluated in the community-setting in a large household-based injury surveillance survey in southwest Cameroon. The CBS test was subsequently incorporated into the Cameroon Trauma Registry, a prospective multi-site national hospital-based trauma registry, and cross-validated in the hospital setting using objective injury metrics in patients presenting to four trauma hospitals. Among 8065 surveyed household members with 503 injury events, individuals with CBS indicators (CBS+) were more likely to report ongoing disability after injury compared to CBS- individuals (OR 1.9, p = 0.004), suggesting the CBS test is a promising injury severity proxy. In 9575 injured patients presenting for formal evaluation, the CBS test strongly predicted death in patients after controlling for age, sex, socioeconomic status, and injury type (OR 30.26, p<0.0001). Compared to established injury severity scoring systems, the CBS test comparably predicts mortality (AUC: 0.8029), but is more feasible to calculate in both the community and clinical contexts. The CBS test is a simple, valid surrogate metric of injury severity that can be deployed widely in community-based surveys to improve estimates of injury severity in under-resourced settings.

A qualitative study of perception related to risky driving behavior in Debre Markos City, North West Ethiopia, 2021

BACKGROUND

About 1.35 million deaths and around 50 million injuries are attributed to road traffic crashes every year in the world. In Ethiopia, road traffic crashes contributed to a fatality rate of 37 per 100,000 populations per year, and 83% of traffic crashes were attributed to risky driving behavior. This study aimed to explore perceptions related to risky driving behavior among public transport vehicle drivers in Debre Markos City, North West Ethiopia, in 2021.

METHODS

A generic qualitative study was conducted from August 05- September 15, 2021. A total of 17 participants (10 drivers, 4 drivers' training school instructors, and 3 traffic police officers) were selected by a purposive heterogeneous sampling technique. An open-ended interview guide was used during the interview, and all interviews were audio recorded. Data collected in the local language was transcribed verbatim and translated into English. The ATLAS-TI version 7.5 software was used to code the data, and finally, thematic analysis was done.

RESULT

Four themes were identified. The first theme was "transport safety rule and enforcement problem," which includes gaps in the transport safety rule itself and gaps in the implementation of the rule. The second theme was "Drivers' training curriculum and application gaps," which focuses on gaps in the training curriculum and its application during recruitment, training, and examination of trainees. The third theme was "technical and financial problems". This theme includes problems related to the vehicles' technical issues and the appropriateness of transport tariffs. The final theme was "passenger and vehicle owners' related problems". This theme is about the influence of passengers' and vehicle owners' practices on drivers' risky driving behavior.

CONCLUSION

Revising transport safety rules and strictly following the implementation of the drivers' training curriculum and transport safety rules should be given due attention. In addition, behavior change communications tailored to drivers and vehicle owners could be beneficial in reducing risky driving behaviors.

The burden of unhelmeted motorcycle injury: A nationwide scoring-based analysis of helmet safety legislation

INTRODUCTION

Motorcycle collisions comprise a large portion of motor vehicle injuries and fatalities with over 80,000 injuries and 5,500 fatalities per year in the United States. Unhelmeted riders have poor medical outcomes and generate billions in costs. Despite helmet use having been shown to lower the risk of neurological injury and death, helmet compliance is not universal, and legislation concerning helmet use also varies widely across the United States.

METHODS

In this study, we systematically reviewed helmet-related statutes from all US jurisdictions. We evaluated the stringency of these statutes using a legislative scoring system termed the Helmet Safety Score (HSS) ranging from 0-7 points, with higher scores denoting more stringent statutes. Regression modeling was used to predict unhelmeted mortality using our safety scores.

RESULTS

The mean score across all jurisdictions was 4.73. We found jurisdictions with higher HSS's generally had lower percentages of unhelmeted fatalities in terms of total fatalities as well as per 100,000 people and 100,000 registered motorcycles. In contrast, some lower-scoring jurisdictions had over 100 times more unhelmeted fatalities than higher-scoring jurisdictions. Our HSS significantly predicted unhelmeted motorcycle fatalities per 100,000 people (β = -0.228 per 1-point increase, 95% CI: -0.288 to -0.169, p < .0001) and per 100,000 registered motorcycles (β = -6.17 per 1-point increase, 95% CI: -8.37 to -3.98, p < .0001) in each state. Aspects of our score concerning helmet exemptions for riders and motorcycle-type vehicles independently predicted higher fatalities (p < .0001). Higher safety scores predicted lower unhelmeted fatalities.

CONCLUSION

Stringent helmet laws may be an effective mechanism for decreasing unhelmeted mortality. Therefore, universal helmet laws may be one such mechanism to decrease motorcycle-related neurological injury and fatality burden. In states with existing helmet laws, elimination of exemptions for certain riders and motorcycle-type vehicles may also decrease fatalities.

Current and Future Trends in Driver Behaviour and Traffic Safety Scholarship: An African Research Agenda

Road traffic accidents are strongly associated with driver behaviour. Africa, as a region, has the highest road accident fatality rate, but there is very little research dealing with this critical issue on the continent. This paper, therefore, sought to establish the state of driver behaviour and road safety scholarship in Africa to determine current research trends as well as potential future research directions. To this end, two bibliometric analyses were conducted, one which considered the issue from an African perspective and the other which considered the broader body of work. The analysis revealed a critical shortage of research related to driver behaviour in Africa. The existing body of research primarily focused on the identification of issues and tended to focus on narrow research problems within limited geographical areas. A need was identified for the collection of broader macro-level data and statistical analyses thereof to indicate regional traffic crash patterns; causes and effects; country-level studies, particularly countries with high traffic fatality rates and low levels of research; cross-country comparisons; and modelling. Future research directions should also include the link between driver behaviour, traffic safety and the sustainable developments goals, as well as policy-related research to determine current and potential future country-level policies.

Limb Injuries and Disability in the Southwest Region of Cameroon

INTRODUCTION

Extremity injuries are a leading cause of morbidity in low- and middle-income countries (LMICs), often resulting in marked short-term and long-term disabilities. Most of the existing knowledge on these injuries originates from hospital-based studies; however, poor access to health care in LMICs limits these data because of inherent selection bias. This subanalysis of a larger population-level cross-sectional study in the Southwest Region of Cameroon aims to determine patterns of limb injury, treatment-seeking behaviors, and predictors of disability.

METHODS

Households were surveyed in 2017 on injuries and subsequent disability sustained over the previous 12 months using a three-stage cluster sampling framework. Subgroups were compared using the chi square, Fisher exact, analysis of variance, Wald, and Wilcoxon rank-sum tests. Logarithmic models were used to identify predictors of disability.

RESULTS

Of 8,065 subjects, 335 persons (4.2%) sustained 363 isolated limb injuries. Over half of the isolated limb injuries (55.7%) were open wounds while 9.6% were fractures. Isolated limb injuries most commonly occurred in younger men and resulted from falls (24.3%) and road traffic injuries (23.5%). High rates of disability were reported, with 39% reporting difficulty with activities of daily living. Compared with individuals with other types of limb injuries, those with fractures were six times more likely to seek a traditional healer first for care (40% versus 6.7%), 5.3 times (95% CI, 1.21 to 23.42) more likely to have any level of disability after adjustment for injury mechanism, and 2.3 times more likely to have difficulty paying for food or rent (54.8% versus 23.7%).

DISCUSSION

Most traumatic injuries sustained in LMICs involve limb injuries and often result in high levels of disability that affect individuals during their most productive years. Improved access to care and injury control measures, such as road safety training and improvements to transportation and trauma response infrastructure, are needed to reduce these injuries.

Characteristics of road traffic accident types and casualties in Guangzhou, China, from 2007 to 2020: A retrospective cohort study based on the general population

Introduction

This study aimed to explore the trend and main influencing factors of road traffic accidents in Guangzhou, China, from 2007 to 2020 and to provide a reference and guidance for government decision-making.

Methods

A retrospective cohort study was used to describe road traffic accidents in Guangzhou. According to the population types, all people with road traffic accidents were divided into migrant workers and the control population. We divided road users, administrative districts, motorcycle types and injury levels into subgroups to investigate the characteristics of road traffic accidents in Guangzhou. The road traffic accident data were derived from the Guangzhou Public Security Traffic Management Integrated System.

Results

The incidence rate of road traffic accidents per 10,000 vehicles in Guangzhou decreased from 36.55 in 2007 to 10.07 in 2012, remained relatively stable at 9.47 in 2017, and finally rose to 11.12 in 2020. The injury rate showed the same trend as the incidence rate, while the mortality rate gradually decreased from 14.21 in 2007 to 5.19 in 2020. Vulnerable road users such as motorized two-to-three-wheeler drivers and migrant workers were casualties in more than 80% of the cases. The proportion of casualties involving mopeds and electric bicycles increased rapidly after 2018. Motor vehicle drivers frequently caused road traffic accidents and were most often uninjured.

Conclusion

Road safety in Guangzhou has shown a clear trend of improvement, but casualties are uneven across administrative districts. More attention should be given to motorized two-to-three-wheelers, migrant workers, and road traffic violations by uninjured individuals.

Characteristics, likelihood and challenges of road traffic injuries in China before COVID-19 and in the postpandemic era

Through a review of previous studies, this paper analysed the epidemiological characteristics and attempts to determine the various trends of road traffic injuries (RTIs) in China before and after the coronavirus disease 2019 (COVID-19). This paper proposed effective measures and suggestions for responding to RTIs in China. Moreover, this paper aimed to provide some references for studies on RTIs in the future. According to a reference review, 50 articles related to RTIs were published and viewed in the China National Knowledge Infrastructure (CNKI), Wanfang database, Weipu (VIP) database and PubMed/MEDLINE database. Articles were selected according to the exclusion and inclusion criteria and then classified and summarized. Regarding cases, RTIs in China were highest in summer, autumn, and in rural areas and lowest in February. Men, elderly individuals and people living in rural areas were more susceptible to RTIs. In addition, thanks to effective and proactive policies and measures, the number of RTIs and casualties in China has substantially decreased, while there has been a growing number of traffic accidents along with the increase in nonmotor vehicles. However, it is worth noting that the number of RTIs obviously fell during the COVID-19 pandemic due to traffic lockdown orders and home quarantine policies. Nevertheless, accidents related to electric bicycles increased unsteadily because of the reduction in public transportation use at the same time. The factors that cause RTIs in China can be divided into four aspects: human behaviours, road conditions, vehicles and the environment. As a result, measures responding to RTIs should be accordingly proposed. Moreover, the road traffic safety situation in developing countries was more severe than that in developed countries. RTIs in China showed a downward trend attributed to road safety laws and various policies, and the downward trend was more significant during the COVID-19 pandemic owing to traffic lockdowns and home quarantine measures. It is urgent and necessary to promote road traffic safety, reduce injuries, and minimize the burden of injuries in developing countries.

Blood donation practice and its predictors among undergraduate college students in Harari Regional State, Eastern Ethiopia

Objectives

The main objective of this study was to assess blood donation practice and its associated factors among undergraduate college students in Harari Region, Eastern Ethiopia.

Methods

An institutional-based cross-sectional study was employed among 518 college students selected by using a simple random sampling technique. Data was collected using pretested structured self-administered questionnaire. The collected data was entered into Epi-data 3.41 and exported to Statistical Package for Social Science version 22 for analysis. Bivariate and multivariable logistic regressions were utilized to identify factors associated with blood donation practice. p-Values of 0.05 or less was used to declare statistical significance.

Results

In this study, the overall blood donation practice was 35.7% (95% confidence interval: 31.6, 39.8). Students studying health sciences were more likely than non-health sciences students (53.5%) to donate blood. Having positive knowledge about blood donation (adjusted odds ratio = 4.17; 95% confidence interval: 2.50, 6.92), being male (adjusted odds ratio = 0.57; 95% confidence interval: 0.38, 0.87), being student of midwifery department (adjusted odds ratio = 2.16; 95% confidence interval: 1.07, 4.36) and nursing department (adjusted odds ratio = 2.42; 95% confidence interval: 1.18, 4.98) were significantly associated with blood donation practice.

Conclusion

Practice of blood donation among college students in the study is relatively low. Knowledge about blood donation, male sex and being a nursing and midwifery student were independently associated with blood donation practice. Therefore, the Regional Health Bureau and Blood Bank in collaboration with college administrators should design and implement appropriate strategies to improve blood donation practice.

Road traffic injuries in Tanzanian children and adolescents: A cross-sectional household survey

OBJECTIVE

To measure annual rates of road traffic injuries (RTI) and to describe the characteristics of road traffic crashes experienced by children and adolescents in Tanga, Tanzania.

METHODS

We conducted a cross-sectional household survey using geospatial population-weighted sampling in the city of Tanga in northern Tanzania. Data were collected in February and March of 2022. We report 12-month rates of road traffic crashes and RTI (reported by adult caregivers) among children and adolescents <18 years of age.

RESULTS

A total of 2,794 adult respondents reported data on 6563 children and adolescents, among whom, 180 were reported to have experienced road traffic crashes in the past 12 months (crash incidence: 27.4 per 1,000 children, 95%CI 23.5-31.4) and 158 sustained injuries (RTI incidence: 24.1 per 1000 children, 95%CI 20.4-27.8). Almost a quarter of RTI (23%) were reported to be major (resulting in ≥30 days of missed activities). RTI was higher among adolescents (13-17 years) than children <5 years (21.5 vs. 14.1 per 1,000, p=0.039). Few children always or sometimes wore helmets when riding on motorcycles/motorbikes (12.8%) or wore safety restraints/seat belts in cars or other vehicles (11.9%).

CONCLUSION

The high rate of road traffic crashes and RTI observed among children and adolescents in a medium-sized city in Tanzania underscores the urgent need to improve road safety and increase use of safety equipment in low resource settings.

Global, Regional, and National Burden of Road Injuries from 1990 to 2019

(1) Background: Understanding occurrence can help formulate effective preventative laws and regulations. However, the most recent global burden and road injuries (RIs) trends have not been reported. This study reports the burden of RIs globally from 1990 to 2019. (2) Methods: RIs data were downloaded from the Global Burden of Disease 2019. Incidence, deaths, and disability-adjusted life years (DALYs) described the trend and burden of RIs. We calculated age-standardized rates (ASRs) and estimated annual percentage change (EAPC) for the above indexes to evaluate the temporal trend of RIs. We evaluated the social-demographic index (SDI) with epidemiological RI parameters and reported proportions of age-standardized rates due to RI. (3) Results: In 2019, the global incidence of RIs reached 103.2 million. The EAPC of RI incidence increased, whereas deaths and DALYs decreased. Age-standardized incident rate (ASIR) was highest in low-middle SDI regions, age-standardized death rate (ASDR) was high in middle SDI regions, and age-standardized DALYs increased in low SDI regions. The highest accident rates were found in those aged 20-24 years old. Cyclist injuries were the leading RIs (34%), though pedestrian and motor vehicle accidents were the leading cause of death (37.4%, 37.6%) and DALYs (35.7%, 32.3%), respectively. (4) Conclusions: Over the past 30 years, RIs incidence increased annually, though death and DALY rates decreased. RIs places a considerable burden on public health in low SDI countries. Data should be used to develop and implement effective measures to reduce the burden of RIs.

Learning about the changing needs for prosthetics service provision from routinely collected digital centre management data: An exemplar study across three clinics in Cambodia

Background

Prosthetic service development and delivery rely on data describing population needs. These needs are context-specific, but most existing data come from high-income countries or small geographic areas, which are often not comparable. This study analysed routinely collected digital patient record data at multiple time points to provide insights into characteristics of people accessing Cambodian prosthetic services.

Methods

We investigated trends in birth year, sex, year and reason for limb absence, and prosthesis type, over three decades. Then, we observed data from 2005 and 2019 indicating how the population actively accessing prosthetics services has changed.

Results

Temporal trends in prosthetics service user demographics corresponded with events in Cambodia's socio-political history. The predominant historical reason for limb absence prior to 2000 was weapon trauma during and following conflict. Since 2000, this was replaced by non-communicable disease and road accidents. Transtibial remained the most prevalent amputation level but transfemoral amputation had higher incidence for people with limb loss from road accidents, and people with limb loss due to disease were older. These observations are important as both transfemoral and older-aged groups experience particular rehabilitation challenges compared to the young, transtibial group.

Conclusions

The study shows how standardised, routinely collected data across multiple clinics within a country can be used to characterise prosthetics service user populations and shows significant changes over time. This indicates the need to track client characteristics and provides evidence for adapting services according to population dynamics and changes in patient need.

Severe traumatic brain injuries secondary to motor vehicle crashes in two Namibian regions: A retrospective review

Introduction

Traumatic Brain Injuries (TBIs) are a leading cause of morbidity and mortality among trauma patients globally, with motor vehicle crashes (MVCs) being a major contributor. Namibia had a World Health Organization (WHO) estimated MVC-related fatality rate of 30.4 per 100 000 population in 2016, higher than that of the African continent, while no epidemiological studies describing the distribution and determinants of TBIs exist in the country. The study aimed to describe the characteristics of adult patients (≥18 years) with severe TBI secondary to MVCs which occurred in two regions of Namibia between the years 2014-2018.

Methods

A retrospective descriptive observational study was conducted in adult patients who sustained severe TBIs secondary to MVCs in two Namibian regions. The inclusion criteria were patients ≥18 years with a severe (as described on the Motor Vehicle Accident Fund system) MVC-related TBI who sustained an injury in the Otjozondjupa or Khomas regions between the years 2014-2018.

Results

A total of 87 patients met the inclusion criteria, 65 (74.7%) from the Khomas region, and 22 (25.3%) from the Otjozondjupa region. The overall mean age of patients was 34 years (SD 11.79), most were male (n = 78. 89.7%) and 55.2% (n = 48) of all patients sustained an isolated TBI. The majority of the patients were admitted to a state healthcare facility (n = 52, 59.8%). Pedestrians were the most injured (n = 34, 52.3%) in the Khomas region while vehicle drivers were the most injured (n = 11, 50%) in the Otjozondjupa Region. A total of 34 (39.1%) patients died and 53 (60.9%) were discharged from hospital. Overall, there were no statistically significant relationships between patient outcomes and independent variables.

Conclusions

The study was to our knowledge the first to describe the epidemiology of TBIs in Namibia. Young individuals are the main people who sustained TBIs, which may subsequently place a socio-economic burden on the country. There is however limited research in Namibia to guide healthcare planning.

Commercial motorcyclists and road safety measures compliance. A case study of Dodoma city, central Tanzania

Objective

Road traffic accidents have been reported to contribute a greater proportion of deaths. Motorcyclists are among the high-risk group within road users to succumb to road traffic accidents. Road traffic accidents reflect the co-occurrence of multiple causes that involve road infrastructure, vehicle, and people. Understanding the level of compliance with road safety measures and their associated factors among commercial motorcyclists is important approach in the steps towards road traffic accident prevention.

Study design

A cross-sectional study of commercial motorcyclists from two districts in Dodoma region was conducted in 2020.

Methods

Multistage sampling method was used to recruit motorcyclists from registered parking stations. At first stage, purposive sampling was used to select the two districts, while in the second stage simple random sampling by lottery method was employed in the selection of wards and parking stations. Descriptive and Chi-square test analyses determined the compliance level. Bivariate and multivariate logistic regression analyses were performed to determine the associated factors.

Results

A total of 378 male commercial motorcyclists participated in the study. Majority (87.8%) were within the age range of 18-29 years. A significant proportion of participants (61.9%) had adequate knowledge and 59.5% showed positive attitude towards road safety measures. Only 39.7% reported to have good level of compliance with road safety measures. Married motorcyclists and those with good road safety practice regarding road safety measures were more likely to comply with road safety measures than their counterpart.

Conclusion

Good road safety practices and marital status were predictors of good compliance with road safety measures. Coordinated approaches, including continuing provision of road safety education and enforcement of road safety measures are needed to control the way motorcyclist behave on the road.

Implementation of a model of awareness-raising for taxi motorcyclists in Benin in relation to helmet use: a quasi-experimental study

Background

This study aims to test the effectiveness of an awareness-raising model designed based on the theory of planned behaviour regarding helmet use for motorcycle taxi drivers.

Methods

This quasi-experimental study took place in the cities of Parakou (intervention group) and Porto Novo (control group). Over a three-month period, a package of awareness-raising activities, based on the theory of planned behaviour, have been implemented in the intervention area. Data relate to knowledge, attitudes and practices regarding helmet use was collected prospectively before the intervention, at the end, and 6 months later. Stata 15 was used for data analysis. Chi-square or Fisher, Student’s or Kruskal-Wallis tests was carried out. The difference-in-difference method was used to determine the specific effect of the awareness activities.

Results

After the intervention, there was an improvement in the total score in both groups compared to baseline. The total score increased by 0.2 (0.06–0.3) in the experimental group when the number of sessions attended increased by one (p = 0.005). The difference-in-difference estimator measured among subjects who attended at least one awareness session, controlling for socio-demographic variables, showed a significantly higher difference in the total score of subjects in the experimental group compared to those in the control group both at the end of the interactive sessions and 6 months later.

Conclusion

This model improves the helmet-wearing behaviour of motorbike taxi drivers in the experimental area. It could be adapted and applied to other socio-professional groups and other types of users.

The relationship between ambient temperatures and road traffic injuries: a systematic review and meta-analysis

Traffic accidents cause considerable economic losses and injuries. Although the adverse effects of a change in ambient temperatures on human health have been widely documented, its effects on road traffic safety are still debated. This systematic review and meta-analysis was performed to synthesize available data on the association between ambient temperature and the risks of road traffic accidents (RTAs) and traffic accident injuries (TAIs). We searched 7 different databases to locate studies. The subgroup analyses were stratified by temperature type, temperature exposure, region, mean temperature, mortality, study period, statistical model, and source of injury data. This study was registered with PROSPERO under the number CRD42021264660. This is the first meta-analysis to investigate the association between ambient temperature and road traffic safety. A total of 34 high-temperature effect estimates were reported, and two additional studies reported the relationship between low temperatures and TAI risk. The meta-analysis results found a significant association between the high temperature and RTAs, and the pooled RR was 1.025 (95%CI 1.014, 1.035). The risk of TAI was also significantly associated with temperature increases. Subgroup analyses found that using daily mean temperatures, the RR value of road traffic accidents was 1.024 (95%CI 0.939, 1.116), and the RR value of road traffic injuries was 1.052 (95%CI 1.024, 1.080). Hourly temperatures significantly increased the risk of RTA, while the risk of TAI was not significantly increased by hourly temperature. The sensitivity analysis indicated that the results were stable, and no obvious publication bias was detected. The results of this systematic review and meta-analysis suggest that increases in ambient temperature are associated with an increased risk of RTAs and TAIs. These findings add to the evidence of the impact of ambient temperature on road traffic safety.

Using social media in Kenya to quantify road safety: an analysis of novel data

BACKGROUND

Road traffic injuries are a large and growing cause of morbidity and mortality in low- and middle-income countries, especially in Africa. Systematic data collection for traffic incidents in Kenya is lacking and in many low- and middle-income countries available data sources are disparate or missing altogether. Many Kenyans use social media platforms, including Twitter; many road traffic incidents are publicly reported on the microblog platform. This study is a prospective cohort analysis of all tweets related to road traffic incidents in Kenya over a 24-month period (February 2019 to January 2021).

RESULTS

A substantial number of unique road incidents (3882) from across Kenya were recorded during the 24-month study period. The details available for each incident are widely variable, as reported and posted on Twitter. Particular times of day and days of the week had a higher incidence of reported road traffic incidents. A total of 2043 injuries and 1503 fatalities were recorded.

CONCLUSIONS

Twitter and other digital social media platforms can provide a novel source for road traffic incident and injury data in a low- and middle-income country. The data collected allows for the potential identification of local and national trends and provides opportunities to advocate for improved roadways and health systems for the emergent care from road traffic incidents and associated traumatic injuries.

Road Safety Policy in Addis Ababa: A Vision Zero Perspective

In this article, the Addis Ababa city road safety policies are examined and analysed based on the Vision Zero approach to road safety work. Three major policy documents are explored and assessed in terms of how they compare with Vision Zero policy in Sweden, concerning how road safety problems are conceptualised, the responsibility ascriptions promoted, the nature of goal setting concerning road safety objectives, and the specific road safety interventions promoted. It is concluded that there is a big difference between the Swedish Vision Zero approach to road safety work and the Addis Ababa road safety approach in terms of how road safety problems are framed and how responsibility ascriptions are made. In Addis Ababa, policy documents primarily frame road safety problems as individual road user problems and, hence, the responsibility for traffic safety is mainly left to the individual road users. The responsibility extended to other system components such as the vehicles, road design, and the operation of the traffic is growing but still very limited. It is argued that in order to find and secure long-term solutions for traffic safety in the city, a paradigm shift is needed, both regarding what are perceived to be the main causes of road safety problems in the city and who should be responsible for ensuring that road fatalities and injuries are prevented.

Do motorcycle helmets reduce road traffic injuries, hospitalizations and mortalities in low and lower-middle income countries in Africa? A systematic review and meta-analysis

BACKGROUND

Studies in Africa have examined the association between helmet use and injury prevention, however, there has been no systematic review to synthesize the literature within an African context nor has there been any meta-analysis examining the effect of helmet use on injury prevention.

METHODS

The review was performed in accordance with the Joanna Briggs Institute for Systematic Reviews. Articles were searched using several databases (e.g. CINAHL, OVID Medline) and select gray literature (e.g. TRID) sources. Articles were included if they were quantitative studies published in English between 2000 and 2019 and examined the association between motorcycle helmet use with head injuries, hospitalizations, and deaths in low- and lower-middle income countries in Africa with comprehensive motorcycle helmet laws. A meta-analysis was performed using pooled effect sizes assessing the impact of helmet use on reducing head injuries.

RESULTS

After screening 491 articles, eight studies met the inclusion criteria. Helmet use ranged from 0 to 43%. The mean age of being involved in a crash was 30 years with males being two times more likely to be involved in motorcycle crashes than females. Drivers (riders) were more likely to be involved in a crash, followed by passengers and then pedestrians. Helmet use reduced injury severity and provided an 88% reduction in serious head injuries (OR 0.118, 95% CI: 0.014-0.968, p = 0.049).

CONCLUSIONS

In our study, helmet usage significantly reduced the likelihood of fatal head injuries. African countries with no helmet laws should consider adopting helmet use policies to reduce severe head related injuries from motorcycle crashes.

A Systematic Review on the Role of Substance Consumption in Work-Related Road Traffic Crashes Reveals the Importance of Biopsychosocial Factors in Prevention

Objective: Since many jobs imply driving, a relevant part of all road traffic crashes (RTC) is related to work. Statistics considering all crashes suggest that they are significantly associated with consumption of substances, but the root causes are not yet clear. The objective of the present paper was to systematically review the scientific literature concerning substances consumption and work-related RTC. We queried the PubMed and Scopus electronic databases according to the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) guidelines. Articles were included if they reported all necessary data and survived a quality assessment. We selected a final sample of 30 articles from an initial pool of 7113. As hypothesized, taking any of the considered substances was found to increase the risk of work-related RTC. Descriptive statistics on work-related RTC showed a higher average positivity rate for medicines (14.8%) than for alcohol (3.02%) and drugs (0.84%). Interestingly, the impact of some medications found an unconvincing explanation in the mere occurrence of side effects, and it suggests that psychosocial and/or medical conditions could be better predictors of RTC. We therefore propose an intervention and prevention model that also considers biopsychosocial factors, for which further studies are needed in future research.

Identifying Research Priorities in Musculoskeletal Trauma Care in Sub-Saharan Africa

Background

In low and middle-income countries (LMICs), individuals suffer from a disproportionately higher number of musculoskeletal (MSK) injuries compared with those living in a high-income setting. However, despite the higher burden of death and disability from MSK injuries in LMICs, there has been little policy, research, and funding invested in addressing this distinctly overlooked problem. Using a consensus-based approach, the aim of this study was to identify research priorities for clinical trials and research in MSK trauma care across sub-Saharan Africa.

Methods

A modified Delphi technique was utilized; it involved an initial scoping survey, a 2-round Delphi process, and, finally, review by an expert panel with members of the Orthopaedic Research Collaboration in Africa. This study was conducted among MSK health-care practitioners treating trauma in sub-Saharan Africa.

Results

Participants from 34 countries across sub-Saharan Africa contributed to the 2 rounds of the Delphi process, and priorities were scored from 1 (low priority) to 5 (high priority). Public health topics related to trauma care ranked higher than those focused on clinical effectiveness, with the top 10 public health research questions scoring higher than the top 10 questions for clinical effectiveness. Ten public health and 10 clinical effectiveness questions related to MSK trauma care were identified; the highest-ranked questions in the respective categories were related to education and training and to the management of femoral fractures.

Conclusions

This consensus-driven research priority study will guide health-care professionals, academics, researchers, and funders to improve the evidence on MSK trauma care across sub-Saharan Africa and inform funders about priority areas of future research.

Out-of-pocket payments and catastrophic expenditures due to traffic injuries in Ouagadougou, Burkina Faso

OBJECTIVE

To estimate the out-of-pocket expenditures linked to Road Traffic Injuries in Ouagadougou, Burkina Faso, as well as the prevalence of catastrophic expenditures among those out-of-pocket payments, and to identify the socio-economic determinants of catastrophic expenditures due to Road Traffic Injuries.

METHODS

We surveyed every admission at the only trauma unit of Ouagadougou between January and July 2015 at the time of their admission, 7 days and 30 days later. We estimate a total amount of out-of-pocket expenditures paid by each patient. We considered an expense as catastrophic when it represented 10% at least of the annual global consumption of the patient's household. We used linear models to determine if socio-economic characteristics were associated to a greater or smaller ratio between out-of-pocket payment and global annual consumption.

FINDINGS

We surveyed 1323 Road injury victims three times (admission, Days 7 and 30). They paid in average 46,547 FCFA (83.64 US dollars) for their care, which represent a catastrophic expenditure for 19% of them. Less than 5% of the sample was covered by a health insurance scheme. Household economic status is found to be the first determinant of catastrophic health expenditure occurrence, exhibiting a significant and negative on the ratio between road injury expenditures and global consumption.

CONCLUSION

Our findings highlight the importance of developing health insurance schemes to protect poor households from the economic burden of road traffic injuries and improve equity in front of health shocks.

Needs for International Benchmarking of Road Safety Management Based on Mobility Exposure Measures and Risk Patterns

Each year, 1.35 million people worldwide die due to Road Traffic Injuries (RTI), highlighting the need for further research. The risk of RTI is usually estimated as the number of casualties divided by the level of exposure in a population. Identifying the most appropriate exposure measures is one of the most important current challenges in this field. This paper presents an analysis of exposure measures used in empirical studies on road accidents. The results show a large variability in the exposure measures used, ranging from more general measures (such as population figures or vehicle fleet) to more specific measures related to mobility (such as number of trips, distances or travel time). A comparison of the risk patterns found shows that there is a partial consensus on the profiles with the highest risk of road traffic injuries. In conclusion, there is a need for the international standardization of criteria and data to be recorded, at least injury severity and measures of exposure to mobility, as the travel time disaggregated by socio-demographic variables and mode of transport. Such data would provide higher-quality results on risk profiles and facilitate the implementation of more effective, knowledge-based road safety policies.

Injury burdens and care delivery in relation to the COVID-19 pandemic in Kigali, Rwanda: A prospective interrupted cross-sectional study

Introduction

Injuries cause significant burdens in sub-Saharan Africa. In Rwanda, national regulations to reduce COVID-19 altered population mobility and resource allocations. This study evaluated epidemiological trends and care among injured patients preceding and during the COVID-19 pandemic at the Centre Hospitalier Universitaire de Kigali (CHUK) in Kigali, Rwanda.

Methods

This prospective interrupted cross-sectional study enrolled injured adult patients (≥15 years) presenting to the CHUK emergency department (ED) from January 27th-March 21st (pre-COVID-19 period) and June 1st-28th (intra-COVID-19 period). Trained study personnel continuously collected standardized data on enrolled participants through the first six-hours of ED care. The Kampala Trauma Score (KTS) was calculated as a metric of injury severity. Case characteristics prior to and during the pandemic were compared, statistical differences were assessed using χ² or Fisher's exact tests.

Results

Data were collected from 409 pre-COVID-19 and 194 intra-COVID-19 cases. Median age was 32, with a male predominance (74.3%). Road traffic injuries (RTI) were the most common injury mechanism pre-COVID-19 (47.8%) and intra-COVID-19 (53.6%) (p = 0.27). There was a significant increase in the number of transfer cases during the intra-COVID-19 period (52.1%) versus pre-COVID-19 (41.3%) (p = 0.01). KTS was significantly lower among intra-COVID-19 patients (p = 0.04), indicating higher severity of presentation. In the intra-COVID-19 period, there was a significant increase in the number of surgery consultations (40.7%) versus pre-COVID-19 (26.7%) (p < 0.001). The number of hospital admissions increased from 35.5% pre-COVID-19 to 46.4% intra-COVID-19 (p = 0.01). There was no significant mortality difference pre-COVID-19 as compared to the intra-COVID-19 period among injured patients (p = 0.76).

Conclusion

Emergency injury care showed increased injury burden, inpatient admission and resource requirements during the pandemic period. This suggests the spectrum of disease may be more severe and that greater resources for injury management may continue to be needed during the ongoing COVID-19 pandemic in Rwanda and other similar settings.

The Built Environment and Health in Low- and Middle-Income Countries: a Review on Quantitative Health Impact Assessments

PURPOSE OF REVIEW

Features and attributes of the built environment (BE) impact positively and negatively on health, especially in cities facing unprecedented urban population growth and mass motorization. A common approach to assess the health impacts of built environment is health impact assessment (HIA), but it is rarely used in low- and middle-income countries (LMICs) where urbanization rates are fastest. This article reviews selected HIA case studies from LMICs and reports the methods and tools used to support further implementation of quantitative HIAs in cities of LMICs.

RECENT FINDINGS

In total, 24 studies were reviewed across Algeria, Brazil, China, India, Iran, Kenya, Thailand, Turkey, and Mauritius. HIAs examine specific pathways through which the built environment acts: air pollution, noise, physical activity, and traffic injury. Few HIAs of BE addressed more than one exposure pathway at a time, and most studies focused on air pollution across the sectors of transport and energy. A wide number of tools were used to conduct exposure assessment, and different models were applied to assess health impacts of different exposures. Those HIAs rely on availability of local concentration data and often use models that have set exposure-response functions (ERFs). ERFs were not adapted to local populations except for HIAs conducted in China. HIAs of BE are being successfully conducted in LMICs with a variety of tools and datasets. Scaling and expanding quantitative health impact modeling in LMICs will require further study on data availability, adapted models/tools, low technical capacity, and low policy demand for evidence from modeling studies. As case studies with successful use of evidence from modeling emerge, the uptake of health impact modeling of BE is likely to increase in favor of people and planet.

Association between alcohol consumption, marijuana use and road traffic injuries among commercial motorcycle riders: A population-based, case-control study in Dares Salaam, Tanzania

BACKGROUND

Alcohol consumption and psychoactive drug use are well-recognised risk factors for road traffic injuries (RTIs). Both types of use may impair and affect drivers' performance. Yet, there is limited literature on their contribution to RTIs among commercial motorcycle riders, particularly in low- and middle-income settings. This study aimed to determine the association between alcohol consumption, marijuana use and RTIs among commercial motorcycle riders in the city of Dar es Salaam, Tanzania.

METHODS

We conducted a case-control study between July 2018 and March 2019. Cases (n = 164) were commercial motorcycle riders who had sustained an RTIs and attended at a hospital. Controls (n = 400) were commercial motorcycle riders who had not experienced an RTIs that led to hospital attendance during the past six months. Alcohol consumption was assessed using the Alcohol Use Disorder Identification (AUDIT) score, which classified participants as a non-drinker, normal drinker(1-7 scores) and risky drinker (scores ≥ 8). Marijuana use was assessed through self-reported use in the past year. We estimated odds ratios (ORs) using logistic regression adjusted for sociodemographic, driver-, and work-related factors.

RESULTS

Risky drinking was associated with close to six times the odds of RTIs compared to non-drinkers (OR = 5.98, 95% CI: 3.25 - 11.0). The association remained significant even after adjusting for sociodemographic, driving and work-related factors (OR = 2.41, 95% CI: 1.01 - 5.76). The crude odds ratios of RTIs were significantly higher among users of marijuana than non-users (OR = 2.33, 95% CI: 1.38 - 3.95). However, the association did not remain statistically significant after adjusting for confounders (OR = 1.11, 95% CI = 0.49-2.48).

CONCLUSION

Our findings confirm increased odds of RTIs among commercial motorcycle riders with risky drinking behaviour even after taking sociodemographic, driving and work-related factors into account. Unlike alcohol consumption the relationship between marijuana use and RTIs among commercial motorcycle riders was unclear. Since motorcycle riders are more susceptible to the effect of alcohol due to higher demands of balance and coordination and because commercial motorcyclist riders, in particular, they spend a considerable amount of time on the road, our results underscore the importance of addressing hazardous alcohol consumption and marijuana use in future prevention strategies to enhance road safety.

Preventable deaths following road traffic collisions in Botswana: A retrospective review

Road traffic collisions (RTC) are a major cause of mortality and morbidity in Botswana. To our knowledge no research has been conducted in Botswana to investigate preventable deaths that occur as a result of RTCs. The aim of this study is to establish the rate of preventable deaths from RTCs in the greater Gaborone area in Botswana. This was a 5-year retrospective study conducted at the forensic pathology department for the greater Gaborone area, in Botswana. Nine hundred and nine (909) forensic pathology reports were retrieved. Sixty-eight percent (68.2%) of RTC deaths were considered preventable. Head injury in isolation and in combination with other injuries accounted for 87.6% (796/909) of deaths. Haemorrhagic shock was present in 70.2% (638) of all documented injuries. Another documented injury contributing to fatal RTCs was high spinal cord injury. This injury was documented in 13.1% (119/909) of all deaths. We recommend the implementation of a comprehensive trauma system in Botswana to reduce the number of deaths from RTCs.

Alcohol and the Risk of Injury

Globally, almost four and a half million people died from injury in 2019. Alcohol's contribution to injury-related premature loss of life, disability and ill-health is pervasive, touching individuals, families and societies throughout the world. We conducted a review of research evidence for alcohol's causal role in injury by focusing on previously published systematic reviews, meta-analyses and where indicated, key studies. The review summarises evidence for pharmacological and physiological effects that support postulated causal pathways, highlights findings and knowledge gaps relevant to specific forms of injury (i.e., violence, suicide and self-harm, road injury, falls, burns, workplace injuries) and lays out options for evidence-based prevention.

Association between traumatic brain injury (TBI) patterns and mortality: a retrospective case-control study

Background: Low and medium income countries (LMICs) such as Kenya experience nearly three times more cases of traumatic brain injury (TBI) compared to high income countries (HICs). This is primarily exacerbated by weak health systems especially at the pre-hospital care level. Generating local empirical evidence on TBI patterns and its influence on patient mortality outcomes is fundamental in informing the design of trauma-specific emergency medical service (EMS) interventions at the pre-hospital care level. This study determines the influence of TBI patterns and mortality. Methods: This was a case-control study with a sample of 316 TBI patients. Data was abstracted from medical records for the period of January 2017 to March 2019 in three tertiary trauma care facilities in Kenya. Logistic regression was used to assess influence of trauma patterns on TBI mortality, controlling for patient characteristics and other potential confounders. Results: The majority of patients were aged below 40 years (73%) and were male (85%). Road traffic injuries (RTIs) comprised 58% of all forms of trauma. Blunt trauma comprised 71% of the injuries. Trauma mechanism was the only trauma pattern significantly associated with TBI mortality. The risk of dying for patients sustaining RTIs was 2.83 times more likely compared to non-RTI patients [odds ratio (OR) 2.83, 95% confidence interval (CI) 1.62-4.93, p=0.001]. The type of transfer to hospital was also significantly associated with mortality outcome, with a public hospital having a two times higher risk of death compared to a private hospital [OR 2.18 95%CI 1.21-3.94, p<0.009]. Conclusion: Trauma mechanism (RTI vs non-RTI) and type of tertiary facility patients are transferred to (public vs private) are key factors influencing TBI mortality burden. Strengthening local EMS trauma response systems targeting RTIs augmented by adequately resourced and equipped public facilities to provide quality lifesaving interventions can reduce the burden of TBIs.

Association between traumatic brain injury (TBI) patterns and mortality: a retrospective case-control study

Background: Low and medium income countries (LMICs) such as Kenya experience nearly three times more cases of traumatic brain injury (TBI) compared to high income countries (HICs). This is primarily exacerbated by weak health systems especially at the pre-hospital care level. Generating local empirical evidence on TBI patterns and its influence on patient mortality outcomes is fundamental in informing the design of trauma-specific emergency medical service (EMS) interventions at the pre-hospital care level. This study determines the influence of TBI patterns and mortality. Methods: This was a case-control study with a sample of 316 TBI patients. Data was abstracted from medical records for the period of January 2017 to March 2019 in three tertiary trauma care facilities in Kenya. Logistic regression was used to assess influence of trauma patterns on TBI mortality, controlling for patient characteristics and other potential confounders. Results: The majority of patients were aged below 40 years (73%) and were male (85%). Road traffic injuries (RTIs) comprised 58% of all forms of trauma. Blunt trauma comprised 71% of the injuries. Trauma mechanism was the only trauma pattern significantly associated with TBI mortality. The risk of dying for patients sustaining RTIs was 2.83 times more likely compared to non-RTI patients [odds ratio (OR) 2.83, 95% confidence interval (CI) 1.62-4.93, p=0.001]. The type of transfer to hospital was also significantly associated with mortality outcome, with a public hospital having a two times higher risk of death compared to a private hospital [OR 2.18 95%CI 1.21-3.94, p<0.009]. Conclusion: Trauma mechanism (RTI vs non-RTI) and type of tertiary facility patients are transferred to (public vs private) are key factors influencing TBI mortality burden. Strengthening local EMS trauma response systems targeting RTIs augmented by adequately resourced and equipped public facilities to provide quality lifesaving interventions can reduce the burden of TBIs.

Characteristics and Injury Patterns of Road Traffic Injuries in Urban and Rural Uganda-A Retrospective Medical Record Review Study in Two Hospitals

In the ongoing Second Decade of Action for Road Safety, road traffic crashes pose a considerable threat especially in low-income countries. Uganda shows a vast burden of non-fatal injuries and resides at the top range of countries with the highest death rates due to unsafe roads. However, little is known about the differences in road traffic associated injuries between urban and rural areas and potential influence factors. Here, we used a cross-sectional study conducted by a retrospective medical record review from trauma cases admitted in 2016 to hospitals in rural and urban areas in Uganda. Injury severity scores were calculated and descriptive analysis was carried out while multivariate logistic regression was applied to assess significant covariates. According to the 1683 medical records reviewed, the mean age of trauma patients in the dataset under investigation was 30.8 years with 74% male. The trauma in-hospital mortality was 4% while prevalence of traumatic injuries is 56.4%. Motorcycle users (49.6%) and pedestrians (33.7%) were identified as the most vulnerable groups in both urban and rural setting while mild injuries of extremities (61.6%) and the head/neck-region (42.0%) were registered most. The frequency of road traffic injuries was homogenous in the urban and rural hospitals investigated in this study; interventions should therefore be intensified ubiquitously. The identification of significant differences in road traffic crash and injury characteristics provides the opportunity for specific programmes to decrease the socio-economic and health burden of unsafe roads. In addition to law enforcement and introduction of a Systems Thinking approach to road safety including infrastructural and educational concepts, the strengthening of trauma care and health resources is recommended.

A tale of three pandemics: Shining a light on a hidden problem

An “epidemic” is an event in which a disease, infectious or non-infectious, is actively spreading within a population and designated area. The term “pandemic” is defined as “an epidemic occurring worldwide, or over a very wide area, crossing international boundaries and usually affecting a large number of people”.

The global response to the COVID-19 pandemic has not been seen since the outbreak of Human Immunodeficiency Virus in the early eighties. But there is another unseen pandemic running alongside the current COVID-19 pandemic, which affects a vast number of people, crossing international boundaries and occurring in every single country worldwide. The pandemic of traumatic injuries.

Traumatic injuries account for 11% of the current Global Burden of Disease, resulting in nearly 5 million deaths annually and is the third-leading cause of death worldwide. For every trauma-related death, it is estimated that up to 50 people sustain permanent or temporary disabilities. Furthermore, traumatic injuries occur at disproportionately higher rates in low- and middle-income countries, with approximately 90% of injuries and more than 90% of global deaths from injury occurring these countries.

Injuries are increasing worldwide, crossing international boundaries and affecting a large number of people, in the same manner Human Immunodeficiency Virus did in the 1980's and COVID-19 is today. The tremendous global effort to tackle the COVID-19 and Human Immunodeficiency Virus pandemics has occurred whilst ignoring the comparable pandemic of injury. Without change and future engagement with policy makers and international donors this disparity is likely to continue.

Roadside surveys of drinking and driving in Cameroon

OBJECTIVE

This study aimed to assess the prevalence of drinking and driving on roadways in urban areas and highways in Cameroon, and to determine the associations between drinking and driving and socio-demographic factors.

METHODS

A cross-sectional study of motor vehicle drivers was performed on Fridays, Saturdays, and Sundays between May and September 2020 with three driver groups: (1) random motor vehicle drivers (including riders) on major highways, (2) drivers recruited at car stations in Yaoundé, and (3) at fuel stations in Douala. Alcohol was measured using breathalyzers, and a questionnaire collected socio-demographic data.

RESULTS

In total, 2402 motor vehicle drivers were asked to participate in the study and 1701 (70.8%) gave informed consent. The vast majority (98.6%) were men. Drivers aged 30-39 years constituted the largest age group on highways and in Yaoundé, whereas 18-29 years was the largest age group in Douala. The highest prevalence of alcohol was observed among drivers in Yaoundé, which included mainly clandestine taxi car drivers and motorcycle taxi riders, where about 30% had blood alcohol concentrations (BAC) above the legal limit of 0.08%. The proportion with BACs above the legal limit was about 6% among the drivers in Douala, which included mainly motorcycle taxi riders, and about 4% among drivers on highways.

CONCLUSIONS

The findings indicate that drinking and driving is a major traffic safety problem on Cameroonian public roads, especially among motorcycle taxi riders and clandestine taxi drivers in towns, which represent the major mass transportation means in the country. Drinking and driving education and legislation should be better developed and enforced in order to reduce the number road traffic crashes.

Compliance of commercial motorcycle riders with road safety regulations in a peri-urban town of Ghana

BACKGROUND

While motorcycles are essential for moving people and goods, they are also, a significant contributor to Road Traffic Accidents (RTAs), making it a public health issue of concern globally. The Hohoe Municipal Hospital records increasing RTAs due to commercial motorcycles. Determining motorcycle riders' compliance with road safety regulations is critical in helping to curb this menace.

METHOD

A cross-sectional study was employed involving a multistage sample of 238 motorcycle riders. Data were collected using a pretested structured questionnaire and entered into Epi Data version 3.2 software and exported to STATA software version 12 for analysis. Descriptive and inferential analyses were done while statistical significance was determined at 95% reliability interval and p-value of 0.05.

FINDINGS

The level of compliance with road safety regulations among respondents was 59.2%. The mean age of respondents was 29.9 ± 7.9 years, and all respondents were males. Respondents who did not own their motorbikes were 0.39 times less likely to comply with road safety regulations compared to their counterparts who owned one, while those without alternate occupations were 0.51times less likely to comply with road safety regulations compared to those with an additional occupation. Those aged between 30-39 years and 40-49 years were 2.37 and 4.1 times more likely to comply with road safety regulations, respectively, compared to those aged ≤29 years, and those who did not smoke were 3.15 times more likely to comply with road safety regulations than those who smoked.

CONCLUSION

Compliance to safety regulations are fairly low and although motorcycle usage on a commercial basis is yet to be legalised in Ghana, routine education targeting riders who smoke, do not have alternate occupations, do not own motorbikes and younger riders will improve their compliance. Also, riders should be encouraged to obtain their license from the appropriate authorities.
