Injury control in Africa: getting governments to do more

Causes of death at the University of Ghana Hospital in Accra-a 37-year review (1979-2015)

Background

An analysis of the causes of death in developing countries is needed to improve healthcare delivery. The aim of this study was to conduct a descriptive analysis of the causes of death at the University of Ghana Hospital from 1979 to 2015.

Methods

Data were extracted from the electronic database of the University of Ghana Hospital. Diseases were grouped into three broad groups of causes of death as per the Global Burden of Disease cause list, with some diseases of epidemiological importance outlined and analysed by age, gender and time in years.

Results

Of 3263 deaths, almost 60% were caused by non-communicable diseases (NCDs) that consisted of cancers, diabetes mellitus, cardiovascular diseases and other systemic conditions. Deaths by malaria, tuberculosis, diarrhoeal diseases and immunizable childhood diseases declined over the years while deaths from NCDs increased. The majority of cases of NCDs were due to cardiovascular disorders.

Conclusions

The study suggests that Ghana has a double burden of disease with predominantly NCDs from cardiovascular diseases, metabolic disorders and cancers. Although malaria and other childhood-related illnesses have declined significantly, human immunodeficiency virus is fuelling the communicable disease mortalities. There is an urgent need to scale up NCD control interventions while strengthening communicable disease control.

Relative household wealth and non-fatal road crashes: analysis of population-representative data of Kenyan adults

Background

This study aims to examine potential road crash disparities across relative wealth and location of residence in Kenya by analyzing population-representative Demographic and Health Survey data.

Methods

Relative wealth was measured by household assets, converted into an index by polychoric principal components analysis. Location and sex-stratified associations between wealth quantiles and crashes were flexibly estimated using fractional polynomial models. Structural equation models were fit to examine whether observed differences may operate through previously identified determinants.

Results

In rural areas, crashes were least common for both the poorest men (-5.2 percentage points, 95% CI: -7.3 to -3.2) and women (-1.6 percentage points, 95% CI: -2.9 to -0.4). In urban areas, male crashes were lowest (-3.0 percentage points, 95% CI: -5.2 to -0.8) among the wealthiest, while they peaked in the middle of the female wealth distribution (2.0 percentage points, 95% CI: 0.3-3.8). Male differences operate partially though occupational driving and vehicle ownership. Urban female differences operate partially through household vehicle ownership, but differences for rural women were not explained by modeled determinants.

Conclusions

Relative wealth and road crash have opposite associations in rural and urban areas. Especially in rural areas, it is important to mitigate potential unintended effects of economic development.

Hospital mortality following trauma: an analysis of a hospital-based injury surveillance registry in sub-Saharan Africa

IMPORTANCE

Injuries are a significant cause of death and disability, particularly in low- and middle-income countries. Health care systems in resource-poor countries lack personnel and are ill equipped to treat severely injured patients; therefore, many injury-related deaths occur after hospital admission.

OBJECTIVES

This study evaluates the mortality for hospitalized trauma patients at a tertiary care hospital in Malawi.

DESIGN

This study is a retrospective analysis of prospectively collected trauma surveillance data. We performed univariate and bivariate analyses to describe the population and logistic regression analysis to identify predictors of mortality.

SETTING

Tertiary care hospital in sub-Saharan Africa.

PARTICIPANT

Patients with traumatic injuries admitted to Kamuzu Central Hospital between January 2010 and December 2012.

MAIN OUTCOME MEASURES

Predictors of in-hospital mortality.

RESULTS

The study population consisted of 7559 patients, with an average age of 27 years (±18 years) and a male predominance of 76%. Road traffic injuries, falls, and assaults were the most common causes of injury. The overall mortality was 4.2%. After adjusting for age, sex, type and mechanism of injury, and shock index, head/spine injuries had the highest odds of mortality, with an odds ratio of 5.80 (2.71-12.40).

CONCLUSION AND RELEVANCE

The burden of injuries in sub-Saharan Africa remains high. At this institution, road traffic injuries are the leading cause of injury and injury-related death. The most significant predictor of in-hospital mortality is the presence of head or spinal injury. These findings may be mitigated by a comprehensive injury-prevention effort targeting drivers and other road users and by increased attention and resources dedicated to the treatment of patients with head and/or spine injuries in the hospital setting.

High incidence of interpersonal violence in Northwest Ethiopia: A cross-sectional study

BACKGROUND

Interpersonal violence has devastating consequences for the mental, physical and sexual health of the victim. It is a leading cause of injury in east Africa. Studies in Ethiopia report that the most common cause of injury was interpersonal conflict. Our objective was to study the incidence of interpersonal violence related injury and associated factors among patients visiting the emergency department of University of Gondar Hospital, Northwest Ethiopia.

METHODS

A cross-sectional institutional based study design was employed from November 2013-June 2014. The source population was a cohort sample of all patients presenting for treatment of a traumatic injury. Data were collected using injury surveillance guidelines developed by the World Health Organization. Bivariate and multivariate logistic regressions were performed to identify the presence and strength of association. Odds ratio with 95% confidence interval was computed to determine the level of significance.

RESULTS

The overall incidence of interpersonal violence related injury was 28.5% of all emergency department trauma patients. Multivariate logistic regression shows that conflict in the family prior to the event [AOR = 9.9 (95% CI: 4.433-9.536)], poor behavioral control [AOR = 2.5 (95% CI: 1.192-5.460)], alcohol use [AOR =  .406 (95% CI: 1.813-6.398)] and paternal education [AOR = 2.441(95% CI: 1.209-4.929)] were found to be independently associated with interpersonal violence related injury.

CONCLUSION AND RECOMMENDATION

The incidence of interpersonal violence related injury was high. Counseling and education on conflict resolution methods should be given for the community using mass media.

The burden of trauma in four rural district hospitals in Malawi: a retrospective review of medical records

BACKGROUND

Few injury surveillance systems collect data in sub-Saharan Africa. This medical record review of four rural hospitals provides baseline data on the burden of trauma in Malawi.

METHODS

We reviewed all outpatient, inpatient, and mortuary records for one full year at four of the 28 district hospitals in Malawi: Dedza in central Malawi, Mangochi in the east, Nkhata Bay in the north, and Thyolo in the south. We used descriptive and comparative statistics to examine characteristics of patients and the data file.

RESULTS

During 2012, 18,735 trauma patients were treated at the four district hospitals. Trauma cases accounted for 3.5% of the 541,170 patient visits. In total, 60.8% of trauma patients were male; 39.1% were 0–14 years old and 50.4% were 15–49 years old. The logbooks were missing information about the primary type of injury for 44.9% of patients and about injury cause for 82.7%. Of the recorded trauma diagnoses, the most common injuries were soft tissue injuries, fractures, and sprains. The most commonly reported causes of injuries were animal bites (mostly dog bites), road traffic injuries, assaults, burns, and falls.

CONCLUSIONS

The development and implementation of improved methods for acquiring more complete, accurate, and useful trauma data in Malawi and other low-income countries requires addressing difficulties that might result in missing data. Increased injury surveillance is critical for improving trauma care and meeting the emerging global demand for burden of disease data.

The influence of anger, impulsivity, sensation seeking and driver attitudes on risky driving behaviour among post-graduate university students in Durban, South Africa

INTRODUCTION

Road traffic accidents (RTAs) constitute a serious global health risk, and evidence suggests that young drivers are significantly overrepresented among those injured or killed in RTAs. This study explores the role of anger, impulsivity, sensation seeking and driver attitudes as correlates for risky driving practices among drivers, drawing comparisons between age and gender.

METHOD

The study used a cross-sectional survey design, with a sample of 306 post-graduate university students from two universities in Durban, South Africa, who completed the self-administered questionnaire.

RESULTS

The results indicate that drivers with higher driver anger, sensation seeking, urgency, and with a lack of premeditation and perseverance in daily activities were statistically more likely to report riskier driving acts. Males reported significantly more acts of risky driving behaviour (RDB) than females. Driver attitudes significantly predicted self-reported acts of RDB on most indicators. Older drivers (25 years and older) had safer driver attitudes and a lower sense of sensation seeking and urgency in life.

CONCLUSION

Interventions targeting young drivers, which focus on impeding the manifestation of anger, impulsivity and sensation seeking are recommended. Also, the empirical support for the attitude-behaviour hypothesis evidenced in this study vindicates the development or continuation of interventions that focus on this dynamic.

Fatal injuries in the slums of Nairobi and their risk factors: results from a matched case-control study

Injuries contribute significantly to the rising morbidity and mortality attributable to non-communicable diseases in the developing world. Unfortunately, active injury surveillance is lacking in many developing countries, including Kenya. This study aims to describe and identify causes of and risk factors for fatal injuries in two slums in Nairobi city using a demographic surveillance system framework. The causes of death are determined using verbal autopsies. We used a nested case-control study design with all deaths from injuries between 2003 and 2005 as cases. Two controls were randomly selected from the non-injury deaths over the same period and individually matched to each case on age and sex. We used conditional logistic regression modeling to identity individual- and community-level factors associated with fatal injuries. Intentional injuries accounted for about 51% and unintentional injuries accounted for 49% of all injuries. Homicides accounted for 91% of intentional injuries and 47% of all injury-related deaths. Firearms (23%) and road traffic crashes (22%) were the leading single causes of deaths due to injuries. About 15% of injuries were due to substance intoxication, particularly alcohol, which in this community comes from illicit brews and is at times contaminated with methanol. Results suggest that in the pervasively unsafe and insecure environment that characterizes the urban slums, ethnicity, residence, and area level factors contribute significantly to the risk of injury-related mortality.

Intentional injury reported by young people in the Federated States of Micronesia, Kingdom of Tonga and Vanuatu

Background

Intentional injury presents a threat to the physical and psychological well being of young people, especially in developing countries, which carry the greatest part of the global injury burden. While the importance of this problem is recognized, there are limited population data in low and middle income countries that can guide public health action. The present study investigates the prevalence and distribution of intentional injury among young people in three Pacific Island societies, and examines behavioural and psychosocial factors related to risk of intentional injury.

Methods

Population surveys were conducted with students aged 11–17 years in Pohnpei State in the Federated States of Micronesia (n = 1495), the Kingdom of Tonga (n = 2808) and Vanuatu (n = 4474). Surveys measured self-reported injury and intentional injury, sources of intentional injury, and the range of behavioural, psychological, educational and social variables that may be related to injury risk.

Results

Among boys and girls aged 14–17 years the respective period prevalence of intentional injury was 62% and 56% in Pohnpei, 58% and 41% in Tonga, and 33% and 24% in Vanuatu. The prevalence of intentional injury declined with age in Tonga and Vanuatu, but there was little evidence of an age-trend in Pohnpei. Across the three societies, the major sources of intentional injury among boys were 'other persons' followed by boyfriends/girlfriends and fathers. Mothers, boyfriends/girlfriends and other persons were primary sources of injury among girls. An intentional injury was reported more often by those who had been bullied (OR 1.40–1.66, P < 0.05), by regular smokers in Tonga and Vanuatu (OR 1.52–2.21, P < 0.05), and illicit drug users in Pohnpei and Vanuatu (OR 1.87–1.92, P < 0.05).

Conclusion

Intentional injury was reported extensively in these three populations. Interventions directed towards the school environment and which take into account the role of bullying and drug use need to be considered.

The global burden of non-conflict related firearm mortality

OBJECTIVE

Understanding global firearm mortality is hindered by data availability, quality, and comparability. This study assesses the adequacy of publicly available data, examines populations for whom firearm mortality data are not publicly available, and estimates the global burden of non-conflict related firearm mortality.

DESIGN

The design is a secondary analysis of existing data. A dataset of countries, populations, economic development, and geographic regions was created, using United Nations 2000 world population data and World Bank classifications of economic development and global regions. Firearm mortality data were obtained from governmental vital statistics reported by the World Health Organization and published survey data. A qualitative review of literature informed estimates for the 15 most populous countries without firearm death data. For countries without data, estimates of firearm deaths were made using quartiles of observed rates and peer reviewed literature.

MAIN OUTCOME MEASURES

Non-conflict related firearm deaths.

RESULTS

Global non-conflict related firearm deaths were estimated to fall between 196,000 and 229,000, adjusted to the year 2000. 162,800 firearm deaths adjusted for the year 2000 came from countries reporting data and represent 35% of the world's 186 countries. Public data are not available for 122 of these 186 countries, representing more than three billion (54%) of the world's population, predominately in lower and lower middle income countries. Estimates of firearm death for those countries without data range from 33,200 to 66,200.

CONCLUSIONS

This study provides evidence that the burden of firearm related mortality poses a substantial threat to local and global health.

Childhood injuries from motor vehicle-pedestrian collisions in Wuhan, The People's Republic of China

OBJECTIVES

To examine motor vehicle-pedestrian collision injuries resulting in hospitalisation among children admitted into Wuhan Children's Hospital, The People's Republic of China.

METHODS

From the 1993 to 2004 inpatient data of Wuhan Children's Hospital, we identified injury cases from motor vehicle traffic crashes among children aged 18 years or less using the discharge diagnosis defined by the International Classification of Diseases, Ninth Revision, Clinical Modification (ICD-9-CM). We examined characteristics of injuries from motor vehicle traffic crashes (ICD-9-CM = E810-E819) and then calculated the proportion of injuries from motor vehicle-pedestrian collisions (ICD-9-CM = E814) among all hospitalisations for childhood injuries (ICD-9-CM = 800-959). The trend of injuries from motor vehicle-pedestrian collisions from 1993 to 2004 was described.

RESULTS

Of the 12,939 injuries resulting in hospitalisation among children admitted into Wuhan Children's Hospital during 1993-2004, a total of 528 injuries were caused by motor vehicle traffic crashes. The majority of the injured children in motor vehicle traffic crashes were males (59.3%). In comparison with other traffic injuries, a higher proportion of motor vehicle-pedestrian collisions occurred among children aged 12-15 years. Motor vehicle-pedestrian collision injuries resulted in significantly longer lengths of stay in the hospital than other motor vehicle traffic injuries (19.4 days versus 14.3 days, respectively; t-test = 2.59, p-value < 0.05). The percentage of motor vehicle-pedestrian collision injuries among all hospitalisations for childhood injuries increased significantly from 1.6% (95% confidence interval [CI] = 1.2-2.1) in 1993 to 3.1% (95% CI = 2.7-3.6) in 2004 (p < 0.05).

CONCLUSIONS

Hospitalisations for injuries from motor vehicle-pedestrian collisions at this large children's hospital increased significantly in the past decade. These data underscore the need for additional research and a major concerted effort to prevent motor vehicle-pedestrian collisions among children in China.

Addressing the growing burden of trauma and injury in low- and middle-income countries

Low- and middle-income countries suffer disproportionately from reduced life expectancy and quality of life. Injuries are overlooked as contributors to global inequities in health, yet the long-term disabilities they frequently produce represent a significant burden. The Fogarty International Center of the National Institutes of Health convened a panel of experts in trauma and injury from the United States and low- and middle-income nations to identify research gaps in this area and opportunities to create new knowledge. Panel members identified sustainable programs of research established through stable linkages between institutions in high-income nations and those in low- and middle-income nations as a priority. The resulting benefits of addressing the growing burden of trauma and injury to communities in resource-constrained settings around the world would be substantial.

Strengthening the prevention and care of injuries worldwide

The global burden of injuries is enormous, but has often been overlooked in attempts to improve health. We review measures that would strengthen existing efforts to prevent and treat injuries worldwide. Scientifically-based efforts to understand risk factors for the occurrence of injury are needed and they must be translated into prevention programmes that are well designed and assessed. Areas for potential intervention include environmental modification, improved engineering features of motor vehicle and other products, and promotion of safe behaviours through social marketing, legislation, and law enforcement. Treatment efforts need to better define the most high-yield services and to promote these in the form of essential health services. To achieve these changes, there is a need to strengthen the capacity of national institutions to do research on injury control; to design and implement countermeasures that address injury risk factors and deficiencies in injury treatment; and to assess the effectiveness of such countermeasures. Although much work remains to be done in high-income countries, even greater attention is needed in less-developed countries, where injury rates are higher, few injury control activities have been undertaken, and where most of the world's population lives. In almost all areas, injury rates are especially high in the most vulnerable sections of the community, including those of low socioeconomic status. Injury control activities should, therefore, be undertaken in a context of attention to human rights and other broad social issues.

Psychosocial correlates of the impact of road traffic accidents among South African drivers and passengers

The aim of the study was to investigate the psychosocial consequences and coping strategies among accident victims in South Africa. Participants (138 drivers and 141 passengers) who had been involved in a road traffic accident were approached and interviewed in public places. In both groups the median age group was between 25 years and 34 years. In 34 accidents (12.2%) a family member was killed, in 68 accidents (24.4%) a non-family member was killed in the accident. In 272 accidents 197 (72.4%) persons (both drivers and passengers) were injured and 168 (61.7%) were hospitalized. Eighty-seven drivers (63%) did not perceive themselves at fault and 51 (37%) did. Following the road traffic accident both drivers and passengers showed a significant decline of their well-being. Drivers who perceived themselves to be at fault did not cope better than those not perceiving themselves at fault. Passengers related to the drivers showed more decline in their well-being than those not related. Path analysis for drivers found that holding oneself responsible had a direct, and mediated by self-blame, guilt and family distress, negative effect on personal well-being. In the passengers group, holding the driver or others responsible led, mediated by increased self-blame, feelings of guilt, and family distress, to lower psychological well-being (PWB). Findings have relevant implications for the development of coping strategies to aid victims of road traffic accidents in dealing with their trauma in this African context, which may differ to those in Western societies.

Superstition, risk-taking and risk perception of accidents among South African taxi drivers

The aim of this study was to investigate taxi drivers' superstition and risk perception of accidents as well as risk-taking in an urban area in South Africa. One hundred and thirty drivers of minibuses, so-called "taxis" were interviewed on the basis of: (1) a superstition scale; (2) a risk-taking scale; (3) a list of perceived causes of road traffic accidents. Drivers showed largely superstitious attitudes and expressed a high degree of risk-taking behavior. Superstition was positively correlated with the number of self-reported accidents the drivers had been involved in and the number of accidents they had witnessed. Path analysis revealed a direct path from superstition to accident involvement while the influence of formal education was negligible. Risk-taking was inversely correlated with driving experience and the number of accidents witnessed but not so with the number of accidents involved in. There was no clear pattern of associations between superstition and risk-taking and perceived causes of accidents. Superstition and risk-taking were slightly and inversely correlated with each other. It is concluded that superstition represents an attitude that is associated with a driver's accident risk, and further research on superstitious attitudes among South African drivers is advocated.

Emergency health and risk management in sub-saharan Africa: a lesson from the embassy bombings in Tanzania and Kenya

In 1998, terrorists simultaneously bombed United States Embassies in Dar es Salaam, Tanzania and Nairobi, Kenya. The local response to these bombings was unorganized and ad hoc, indicating the need for basic disaster preparedness and improvement of emergency management capabilities in both countries. In this context, risk and risk management are defined and are related to the health hazards affecting Tanzanians and Kenyans. In addition, the growing number of injuries in Tanzania is addressed and the relationship between risk management and injury is explored. Also, an emergency medicine-based strategy for injury control and prevention is proposed. Implications of implementing such a protocol in developing nations also are discussed.

Injury patterns in rural and urban Uganda

OBJECTIVES

To describe and contrast injury patterns in rural and urban Uganda.

SETTINGS

One rural and one urban community in Uganda.

METHODS

Community health workers interviewed adult respondents in households selected by multistage sampling, using a standardized questionnaire.

RESULTS

In the rural setting, 1,673 households, with 7,427 persons, were surveyed. Injuries had an annual mortality rate of 92/100,000 persons, and disabilities a prevalence proportion of 0.7%. In the urban setting 2,322 households, with 10,982 people, were surveyed. Injuries had an annual mortality rate of 217/100,000, and injury disabilities a prevalence proportion of 2.8%. The total incidence of fatal, disabling, and recovered injuries was 116/1,000/year. Leading causes of death were drowning in the rural setting, and road traffic in the city.

CONCLUSION

Injuries are a substantial burden in Uganda, with much higher rates than those in most Western countries. The urban population is at a higher risk than the rural population, and the patterns of injury differ. Interventions to control injuries should be a priority in Uganda.

Health Behaviour in Black South African University Students

Four important health behaviours – dietary fat avoidance, regular exercise, smoking and alcohol consumption - were assessed by questionnaire, together with measures of risk awareness, beliefs about the importance of each behaviour for health, health status, health locus and health value. The sample included 793 Black University students from non-health courses chosen at random from the University of the North, South Africa. The students were 370 (46.7%) males and 423 (53.3%) females in the age range of 18 to 25 years (M age 21.0 years, SD=3.48). The following prevalences for healthy behaviour was found: almost half (44.7%) avoided fat and cholesterol and likewise 48% had exercised in the past 14 days. More than 90% were non-smokers and 84% were non-drinkers or drank alcohol only very occasionally. Sex emerged as an independent predictor for smoking and drinking. Men smoked and drank more than women did. The level of risk awareness about healthy behaviour seemed to be low in this sample. Risk awareness and prevalence of health behaviour was only found to have significant effects for non-smoking and not for the other health behaviours (exercise, fat intake, alcohol consumption). Beliefs were more important independent predictors of dietary fat intake and exercises than was risk awareness.

An evaluation of sensitivity and specificity of blood alcohol concentrations obtained by a breathalyser survey in a casualty department in Kenya

Whereas breathalysers have been shown to provide blood alcohol concentration (BAC) measurements comparable to those obtained by gas chromatography, such evidence has not been reported in low and middle income countries where measures for preventing alcohol-related injuries are virtually non-existent. Before promoting any method of blood alcohol evaluation, as a routine procedure for monitoring the association of alcohol with different types of injuries in Kenya, we sought to assess the reliability and validity of blood alcohol results obtained by a breathalyser, using gas chromatography analysis values as the reference, in a sample of 179 trauma-affected adults presenting to casualty departments. No differences in proportions of subjects with high levels of blood alcohol (equal to or greater than 50 mg%) were detected by breath and blood test procedures (58.7 vs 60.3%). Breathalyser readings yielded high levels of sensitivity and specificity (97.2 and 100%, respectively) with optimal positive and negative predictive values (100 and 95.9%, respectively) at higher BACs (> or = 50 mg%). The study thus reaffirms that breathalyser tests are of value in detecting high blood alcohol levels and can be used to rapidly identify intoxicated subjects. The procedure is easy to perform and can be used for monitoring the association between blood alcohol level and driving in low-income developing countries.
