Original ArticleProspective Study of Surgery for Traumatic Brain Injury in Addis Ababa, Ethiopia: Trauma Causes, Injury Types, and Clinical Presentation
Introduction
According to recent global estimates, close to 90% of all trauma-related deaths occur in low- and middle-income countries (LMICs).1 Neurological injuries are the most important causes of death and disability from trauma, particularly in children and young adults.2 However, studies on head and spinal injuries from LMICs are underrepresented in the international literature.3,4 Importantly, as different regions have their own needs and obstacles, neurotrauma research and management must be contextualized. It is not feasible to directly transfer cost-demanding, evidence-based guidelines from Western countries to LMICs, which lack the necessary finances, equipment, and human resources. Thus, there is a great need for more and better data on epidemiologic aspects and the entire continuum of care to facilitate development of locally tailored guidelines, improve quality of care, and identify region-specific focus areas for preventive efforts.5,6
Ethiopia is the second most populous country in Africa with about 115 million inhabitants.7 Notably, it is a country of young people, as 70% are <30 years of age.8 Ethiopia has one of the fastest growing economies in the world with a rapid rate of urbanization and industrialization and has some of the highest numbers of road traffic injuries and deaths worldwide.9,10 Fall accidents among construction workers are very common,10 and there are high rates of injuries resulting from violence and assaults.11,12 In studies from the emergency department (ED) at Black Lion Specialized Hospital in Addis Ababa, traumatic brain injury (TBI) was the leading cause of mortality and the most important indication for neurosurgical procedures.13, 14, 15 The burden of trauma, especially neurotrauma, weighs heavily on Ethiopian society,11 and research that can lead to improved patient care and identify relevant focus areas for Ethiopian authorities is timely and highly warranted.
The Ethiopian/Norwegian training program in neurosurgery was started in 2006 and has been instrumental in developing a sustainable neurosurgical environment in Ethiopia.16 A key issue for further development is research, particularly within the most prevalent disease conditions. To this end, we prospectively registered TBI patients who were surgically treated at the 4 teaching hospitals in Addis Ababa in the period 2012–2016. In this article, we describe the trauma causes, injury types, and clinical presentation. In another article, we report on the surgical treatment, complications, and patient outcomes.17

Study Setting
This study was done at the 4 neurosurgical teaching hospitals in Addis Ababa, Ethiopia: Black Lion Specialized Hospital, Myung Sung Christian Medical Center, Alert Hospital, and Zewditu Memorial Hospital. These hospitals provide the majority of neurosurgical services in the country. Hospital management of TBI patients is based on the Advanced Trauma Life Support guidelines and the Brain Trauma Foundation guidelines.18 More details on hospital management are described elsewhere.17 This study is
Demographics and Injury Types
In the study period, 4412 TBI patients (90 patients from October to December 2012, 796 patients in 2013, 942 patients in 2014, 1284 patients in 2015, and 1300 patients in 2016) visited the ED of the 4 hospitals. A total of 1087 patients (24.6%) were surgically treated and included in this study. The mean age was 29 years, and 91.3% were males (Table 1). Female patients were younger than male patients (mean age 24.7 vs. 29.4 years; P = 0.01). Among all patients, 17.1% were children (<18 years
Discussion
In this study, we present novel data on TBI patients who were surgically treated in Ethiopia. Most patients were male adolescents or young adults with a mean age <30 years. DSF and EDH were the most frequent (>80%) injury types, and the majority of patients (>50%) had a GCS score of 14–15 at presentation. Approximately 70% of TBI patients were injured in assaults. Hospital admission was often delayed with a median time to admission of 24 hours. Delayed admission was associated with a nonsevere
Conclusions
TBI is a major public health problem in Ethiopia, and our novel data on neurosurgical management of TBI can help to improve the quality of care and identify focus areas for preventive efforts. Many young patients die or experience significant treatment delay because of limitations within prehospital services and local hospitals, and efforts should be made to address this (e.g., trauma resource allocation, ambulance services, systematic referral systems from district hospitals, telemedicine
