Road Traffic Injuries in Kenya: The Health Burden and Risk Factors in Two Districts

Background: Road traffic injuries (RTIs) contribute to a significant proportion of the burden of disease in Kenya. They also have a significant impact on the social and economic well-being of individuals, their families, and society. However, though estimates quantifying the burden of RTIs in Kenya do exist, most of these studies date back to the early 2000s—more than one decade ago. Objective: This article aims to present the current status of road safety in Kenya. Using data from the police and vital registration systems in Kenya, we present the current epidemiology of RTIs in the nation. We also sought to assess the status of 3 well-known risk factors for RTIs—speeding and the use of helmets and reflective clothing. Methods: Data for this study were collected in 2 steps. The first step involved the collection of secondary data from the Kenya traffic police as well as the National Vital Registration System to assess the current trends of RTIs in Kenya. Following this, observational studies were conducted in the Thika and Naivasha districts in Kenya to assess the current status of speeding among all vehicles and the use of helmets and reflective clothing among motorcyclists. Results: The overall RTI rate in Kenya was 59.96 per 100,000 population in 2009, with vehicle passengers being the most affected. Notably, injuries to motorcyclists increased at an annual rate of approximately 29 percent (95% confidence interval [CI]: 27–32; P < .001). The mean age of death due to road traffic crashes was 35 years. Fatalities due to RTIs increased at an annual rate of 7 percent (95% CI: 6–8; P < .001) for the period 2004 to 2009. Observational studies revealed that 69.45 percent of vehicles in Thika and 34.32 percent of vehicles in Naivasha were speeding. Helmets were used by less than one third of motorcycle drivers in both study districts, with prevalence rates ranging between 3 and 4 percent among passengers. Conclusions: This study highlights the significant burden of RTIs in Kenya. A renewed focus on addressing this burden is necessary. Focusing on increasing helmet and reflective clothing use and enforcement of speed limits has the potential to prevent a large number of road traffic crashes, injuries, and fatalities. However, it is difficult to demonstrate the magnitude of the injury problem to policymakers with minimal or inaccurate data, and this study illustrates the need for national continuous, systematic, and sustainable data collection efforts, echoing similar calls for action throughout the injury literature.

Moving from research ethics review to research ethics systems in low-income and middle-income countries

1Despite sustained attention to the challenges of research-capacity building by developing countries, there have been few attempts to describe how a country’s stage of development relates to the two challenges central to research ethics—protection of research participants and promotion of ethical conduct in research. 2–5

Ethical Review of Health Systems Research in Low- and Middle-Income Countries: A Conceptual Exploration

Given that health systems research (HSR) involves different aims, approaches, and methodologies as compared to more traditional clinical trials, the ethical issues present in HSR may be unique or particularly nuanced. This article outlines eight pertinent ethical issues that are particularly salient in HSR and argues that the ethical review process should be better tailored to ensure more efficient and appropriate oversight of HSR with adequate human protections, especially in low- and middle-income countries. The eight ethical areas we discuss include the nature of intervention, types of research subjects, units of intervention and observation, informed consent, controls and comparisons, risk assessment, inclusion of vulnerable groups, and benefits of research. HSR involving human participants is necessary to ensure health systems strengthening and quality of care and to guide public policy intelligently. Health systems researchers must carefully define their intent and goals and openly clarify the values that may influence the premises and design of protocols. As new types of population-level research activities become more commonplace, it is critical that institutional review board (IRB) and research ethics committee (REC) review processes evolve to evaluate these research protocols in ways that address the nuanced features of these studies.

Patterns of pediatric injury in South Africa: an analysis of hospital data between 1997 and 2006.

BACKGROUND Pediatric injuries are associated with significant morbidity and mortality, especially in low- and middle-income countries. Despite the magnitude of this burden, there is lack of data to characterize the etiology and risk factors associated with childhood injuries, especially in low- and middle-income countries. The aim of this article is to describe the demographics, mechanisms, and severity of injuries during a 10-year time period using hospital-based data in Cape Town, South Africa. METHODS Data from Childsafe South Africa’s registry were used to study injured children younger than 13 years who presented with either intentional or unintentional injuries to the Trauma Unit of the Red Cross War Memorial Children’s Hospital’s (RCH) Causality Department between 1996 and 2007. Univariate and bivariate analyses were performed for demographic characteristics and injury mechanisms. Poisson regression analysis was used to analyze the age-adjusted annual incidence of injury presenting to RCH. RESULTS Between 1997 and 2006, 62,782 children with a total of 68,883 injuries presented to RCH. The mean age was 5.4 years (standard deviation ± 3.5 years) and 61.7% were male. Mechanism of injury included falls (39.8%), road traffic injuries (15.7%), burns (8.8%), and assault (7.4%). The majority of injuries occurred in and around the home. Abbreviated injury severity scoring showed 60.2% of injuries were minor, 36.6% were moderate, and 3.2% were severe. Sixty-six deaths occurred in the trauma casualty department. Thirty-one percent of patients were admitted to the hospital; children who suffered burn and head injuries were more likely to require admission. CONCLUSION Age, gender, mechanism, and severity of injury in pediatric populations have not been described elsewhere in South African national or sub-Saharan regional data. This retrospective, observational study uses Level II evidence to suggest the need for targeted interventions to address risk factors for pediatric injuries, emphasizing the importance of pediatric surveillance systems as a tool to study injuries in developing countries. LEVEL OF EVIDENCE Prognostic study, level II.

Helmet use among motorcyclists in Cambodia: a survey of use, knowledge, attitudes, and practices.

Objective: Road traffic injuries (RTIs) are a leading cause of disability and fatality globally. Motorcycle-related injuries, mainly head injuries, and related deaths and disabilities are a significant contributor to the burden of disease in low- and middle-income countries (LMICs). Helmets have been proven to be an effective way to reduce the risk of head injury. As motorcycle use continually increases in Cambodia, head injuries and related deaths and disabilities are expected to rise. This article aims to assess the current status of helmet use in Cambodia, as well as the knowledge, attitudes, and practices among motorcyclists, in order to assist with better planning and implementation of injury prevention strategies. Methods: Two separate methodologies were employed for this study. Helmet observations were conducted in Phnom Penh, Kandal, Kampong Speu, Siem Reap, and Kampong Cham to assess the current status of helmet use during the day and at night. Roadside knowledge, attitudes, and practice (KAP) interviews were also conducted in Phnom Penh, Kandal, and Kampong Speu to determine the prevailing beliefs around helmet use in Cambodia. Results: Based on observations, the proportion of helmet wearing across all study sites was 25 percent at night and 43 percent during the day among all motorcyclists. The observed proportion was up to 10 times higher among drivers compared to passengers. The top 3 reasons for always wearing a helmet were lifesaving potential, legal duty, and police fines. Almost 60 percent of respondents said that their use or nonuse of a helmet depended on where they were driving. Helmet quality, price, style, and color were important factors influencing the decision to purchase a helmet. Conclusions: A paradox appears to exist in Cambodia; though awareness of the benefits of wearing a helmet is high, actual helmet use remains low in the country. Daytime usage is higher than nighttime, and these proportions are significantly higher among drivers compared to passengers. There is a continuing need to improve the proportion of all-day helmet wearing, especially at night and among motorcycle passengers in Cambodia.

Pediatric burn injuries in South Africa: A 15-year analysis of hospital data

INTRODUCTION Burns are a significant burden of pediatric injuries, particularly in low and middle-income countries, were more than 90% of burn-related pediatric deaths occur. This study explores pediatric burn-related injuries over a fifteen year time period in South Africa through an analysis of a pediatric trauma surveillance system. METHODS This retrospective observational study used data collected by Childsafe South Africa from the Red Cross War Memorial Childrens Hospital (RCH) trauma registry in Cape Town, South Africa between 1995 and 2009 for children less than 13 years of age who presented with burn injuries to the hospitals casualty department. Demographic data and Abbreviated Injury Scores (AISs) were first assessed, followed by an analysis of time trends using Poisson regression. Logistic regression models were used to analyse factors related to hospital admissions. RESULTS Between 1995 and 2009, 9438 children with burn-related injuries presented to RCH, of which nearly three-quarters resulted from scalds (73%; n=7024). The mean age of the injured children was 3.1 ± 2.9 years 58% were male. 11 deaths occurred in the hospitals casualty department. 39% of injuries were minor, 56% were moderate, and 5% were severe. During the 15-year study period, moderate burn injuries increased by 3%, while minor injuries decreased by 10% (p<0.05). 49% of all children were admitted to the hospital. Hospital admissions increased by 3% (p<0.05) during the study period. CONCLUSIONS Pediatric burn injuries are a significant contributor to the burden of child diseases in developing county hospitals. Pediatric surveillance systems, such as Childsafe South Africas, are important to study epidemiologic changes in burn injuries. Findings suggest the need for targeted interventions to address the prevention of specific burn-related injuries.

Drinking and Driving in Vietnam: Public Knowledge, Attitudes, and Practices

Objective: Injuries are among the 10 leading causes of death for all ages in Vietnam, and road traffic fatalities account for approximately half of those deaths. Despite having what is considered to be one of the most stringent alcohol legislations in the region, alcohol involvement in road traffic crashes remains high. This study aims to illustrate the knowledge, attitudes, and practices around alcohol use and drinking and driving by age and sex in 3 provinces in Vietnam. Methods: This study was conducted between January and February 2011, surveying randomly selected road users over the age of 17 years at gas stations in 3 provinces: Ha Nam, Ninh Binh, and Bac Giang, Vietnam. Data were collected for one week at each gas station. A knowledge, attitudes, and practices (KAPs) survey was administered in 7 time blocks of 90 min throughout the day, from 07:30 am to 9:30 pm. Results: There were a total of 633 respondents almost evenly divided among the 3 provinces. Males accounted for 69.1 percent of respondents; the majority were 36 years of age or younger. Despite the belief that drinking and driving will increase the risk of a crash, a significant proportion of respondents (44.9%) reported drinking and driving; 56.7 percent admitted to drinking and driving within the last month. Drinking and driving was more common among males, with approximately 60.2 percent indicating a history of drinking and driving. This proportion was particularly high among males aged 17 to 26 (71.4%). It was found that preferred alternatives to drinking and driving when available were leaving with a nondrinker (42%), resting until “feeling conscious” (23%), and drinking less (20%). Conclusions: This study shows that, in general, alcohol use and drinking and driving remain a problem in Vietnam, a major concern given that the country is rapidly motorizing and likewise increasing the likelihood of road traffic crashes in the absence of effective interventions. To target drinking and driving in Vietnam we call for a multifaceted approach, including social marketing and public education campaigns, enhanced enforcement, and programs that either limit the number of drinks to drivers or young individuals or those that provide alternatives to drinking and driving.

Establishing hospital-based trauma registry systems: lessons from Kenya

OBJECTIVE In the developing world, data about the burden of injury, injury outcomes, and complications of care are limited. Hospital-based trauma registries are a data source that can help define this burden. Under the trauma care component of the Bloomberg Global Road Safety Partnership, trauma registries have been implemented at three sites in Kenya. We describe the challenges and lessons learned from this effort. METHODS A paper-based trauma surveillance form was developed, in collaboration with local hospital partners, to collect data on all trauma patients presenting for care. The form includes demographic information, pre-hospital care given, and patient care and clinical information necessary to calculate estimated injury surveillance. The type of data collected was standardized across all three sites. Frequent reviews of the data collection process, quality, and completeness, in addition to regular meetings and conference calls, have allowed us to optimize the process to improve efficiency and make corrective actions where required. RESULTS Trauma registries have been implemented in three hospitals in Kenya, with potential for expansion to other hospitals and facilities caring for injured patients. The process of establishing registries was associated with both general and site-specific challenges. Problems were identified in planning, data collection, entry processes, and analysis. Problems were addressed when identified, resulting in improved data quality. CONCLUSIONS Trauma registries are a key data source for defining the burden of injury and developing quality improvement processes. Trauma registries were implemented at three sites in Kenya. Problems and challenges in data collection were identified and corrected. Through the registry data, gaps in care were identified and systemic changes made to improve the care of the injured.

Seatbelt wearing rates in middle income countries: A cross-country analysis

In settings with low seatbelt use prevalence, self-reported seatbelt use estimates often lack validity, and routine observational studies are scarce. In this paper, we aim to describe the prevalence of seatbelt use and associated factors in drivers and front-seat passengers across eight sites in four countries (Egypt, Mexico, Russia, Turkey) using observational studies as well as to produce estimates of country-level and site-level variance. As part of the Bloomberg Philanthropies Global Road Safety Program, data on driver and passenger seatbelt use across four middle-income countries was collected between October 2010 and May 2011 (n=122,931 vehicles). Logistic regression and Intraclass Correlation Coefficient analyses for sites- and country-level clustering were performed. We found high variability of seatbelt wearing rates ranging from 4 to 72% in drivers and 3-50% in front-seat passengers. Overall, average seatbelt wearing rates were low (under 60% in most sites). At the individual level, older and female drivers were more likely to wear seatbelts, as well as drivers of vehicles transiting at times of increased vehicle flow. We also found that 26-32% and 37-41% of the variance in seatbelt use among drivers and front-seat passengers respectively was explained by differences across sites and countries. Our results demonstrate that there is room for improvement on seatbelt use in middle-income countries and that standardized cross-country studies on road safety risk factors are feasible, providing valuable information for prevention and monitoring activities.

Assessing trauma care at the district and provincial hospital levels: a case study of hospitals in Kenya

Trauma is a major cause of death and disability worldwide, of which more than 90% occur in low- and middle-income countries. Given the magnitude of this inequality, there is a need to devise and use tools to assess the capacity of facility-based trauma care. This study used two tools, hospital flowcharts and the World Health Organizations Trauma Care Checklist, to describe trauma care capacity at two hospitals in Kenya and ways in which this capacity can be strengthened. We found these hospitals had a large volume of trauma, but due to the lack of intensive care units, specialized trauma units, and axillary services, such as orthopedics and neurosurgery, the hospitals had a limited ability to provide definitive care for injured patients in critical condition. Additionally, organizational capabilities, such as trauma registries, trauma-specific training, and quality improvement programmes were lacking. The state of trauma care at district and provincial levels in Kenya demonstrates a strong case for national and global investment in clinical and systemic interventions.
