In many developing countries there is paucity of evidence regarding the epidemiology of road traffic accidents (RTAs). The study determines the rates of injuries and fatalities associated with RTAs in Ethiopia based on the data of a recent national survey. The study is based on the secondary data of the Ethiopian Demographic and Health Survey conducted in 2016. The survey collected information about occurrence injuries and accidents including RTAs in the past 12 months among 75,271 members of 16,650 households. Households were selected from nine regions and two city administrations of Ethiopia using stratified cluster sampling procedure. Of the 75,271 household members enumerated, 123 encountered RTAs in the reference period and rate of RTA-related injury was 163 (95% confidence interval (CI): 136–195) per 100,000 population. Of the 123 causalities, 28 were fatal, making the fatality rate 37 (95% CI: 25–54) per 100,000 population. The RTA-related injuries and fatalities per 100,000 motor vehicles were estimated as 21,681 (95% CI: 18,090–25,938) and 4,922 (95% CI: 3325–7183), respectively. Next to accidental falls, RTAs were the second most common form of accidents and injuries accounting for 22.8% of all such incidents. RTAs contributed to 43.8% of all fatalities secondary to accidents and injuries. Among RTA causalities, 21.9% were drivers, 35.0% were passenger vehicle occupants and 36.0% were vulnerable road users including: motorcyclists (21.0%), pedestrians (12.1%) and cyclists (2.9%). Approximately half (47.1%) of the causalities were between 15–29 years of age and 15.3% were either minors younger than 15 years or seniors older than 64 years of age. Nearly two-thirds (65.0%) of the victims were males. RTA-related causalities are extremely high in Ethiopia. Male young adults and vulnerable road users are at increased risk of RTAs. There is a urgent need for bringing road safety to the country's public health agenda.

In low and middle income countries road traffic injuries are commonly under-reported. This problem is significantly higher among those less severely injured road users. The objective of this study was to determine the incidence and the level of ascertainment of road traffic injuries and deaths by traffic police and hospital registry. In this study two-sample capture-recapture method was applied using data from traffic police and hospital injury surveillance, through June 2012 to May 2013. The study was conducted on one of the busiest highways in Ethiopia, the Addis Ababa – Hawassa highway. Primary data were collected by accident investigators and hospital emergency nurses using a structured checklist. Four matching variables; name of the victim, sex, place and time of the accidents was used to get the matched cases. During the study period the police independently reported 224 deaths and 446 injuries/billion vehicle kilometer while hospitals reported 123 deaths and 1,046 injuries/billion vehicle kilometer. Both sources in common captured 73 deaths and 248 injuries/billion vehicle kilometer. Taking the two data sources into consideration, the capture-recapture model estimated the incidence of deaths and injuries ranged 368–390 and 1,869–1,895 per billion vehicle kilometer, respectively. The police source captured 57.4%–60.9% of deaths and 23.5%–23.9% of injuries while the hospital sources captured 31.5%–33.4% of deaths and 55.2%–56% of injuries. Deaths and injuries among females, younger age victims, cyclists/motorcyclists and pedestrians were under-reported by traffic police. In conclusion neither of the two sources independently provided accurate coverage of road traffic incident related deaths and injuries. Strengthening both systems is necessary to obtain accurate information on road accidents and human causalities.

Accidental percutaneous injury and acquiring blood-borne diseases are common problems among health care workers (HCWs). However, little is known about the prevalence and associated factors for needle stick injury among HCWs in Ethiopia. A cross sectional study was conducted by including 526 HCWs (physicians, nurses, laboratory technicians, midwives and others), working in two public hospitals (Hawassa Referral and Adare District hospitals), from January 1–30, 2014. Binary logistic regression was done to assess the association of selected independent variables with accidental percutaneous injury. The prevalence of at least one episode of percutaneous injury was about 46 % of which more than half (28 %) occurred within one year prior to the study period and only 24 % took prophylaxis for human immune deficiency virus (HIV) infection. The adjusted logistic regression analysis revealed that HCWs who recap needles were twice as likely to face a percutaneous injury. Chance of exposure to needle stick or sharp injuries also increased with increase in educational status. Having a previous history of needle stick or sharp injury was found as one of the risk factors for the occurrence of another injury. Nurses and cleaners were also at increased risk for the occurrence of percutaneous injuries. Needle stick and sharp injuries were common among HCWs in the study hospitals, which warrants training on preventive methods.

Background: Road Traffic crash injury is one of the main public health problems resulting in premature death and disability particularly in low-income countries. However, there is limited evidence on the crash fractures in Ethiopia. Objective: The study was conducted to assess the magnitude of road traffic crash fractures and visceral injuries. Methods: A hospital-based cross-sectional study was conducted on 420 fracture patients. Participants were randomly selected from Addis Ababa City hospitals. The study was carried out between November 2019 and February 2020. Data were collected using a questionnaire and record of medical findings. Multilevel logistic regression analysis was carried out. Ethical clearance was obtained from the Addis Ababa University, College of Health Sciences Institutional Review Board. Confidentiality of participants’ information was maintained. Results: The study found out that the majority 265 (63. 1%) of fracture cases were younger in the age group of 18 to 34 years. Males were more affected—311(74.0%). The mortality rate was 59(14.1%), of those 50(85.0%) participants were males. The major road traffic victims were pedestrians—220(52.4%), mainly affected by simple fracture type -105(53.3%) and compound fracture type—92(46. 7%). Drivers mainly suffered from compound fracture type -23 (59.0%). One hundred eighty-two (43.3%) of fracture patients had a visceral injury. Homeless persons who sit or sleep on the roadside had a higher risk of thoracic visceral injury compared to traveler pedestrians (AOR = 4.600(95%CI: 1.215–17.417)); P = 0.025. Conclusion: Visceral injury, simple and compound fractures were the common orthopedic injury types reported among crash victims. Males, pedestrians, and young age groups were largely affected by orthopedic fracture cases. Homeless persons who sited or slept on the roadside were significant factors for visceral injury. Therefore, preventing a harmful crash and growing fracture care should be considered to reduce the burden of crash fracture.

A cross-sectional study of safety climate and safety performance was performed in Ethiopian construction sites, among 1203 workers from 22 large-scale construction sites. The Nordic Safety Climate Questionnaire was administered using interviews. We developed a model to show the interrelations between safety climate and performance. This model was examined using factor analysis. Low scores for all seven safety climate dimensions were found, with values ranging from 2.33 to 3.08 and a mean of 2.70. Similarly, the mean score of the safety performance construct was 2.95 for safety participation and 3.58 for safety compliance. A strong positive correlation was found between safety climate and safety performance, and safety involvement accounted for 29.2% of the variance, while safety compliance accounted for 28.6% of the variance. The suggested association between self-reported injuries and safety climate was not confirmed. Nonetheless, Pearson correlation analysis demonstrated a statistically significant negative correlation with safety climate. In conclusion, low scores for all safety climate dimensions show that safety on construction sites must be improved. The safety climate positively influences employees’ safety behavior (safety compliance and safety participation) and minimizes occupational injuries.
