Background: Traumatic brain injury (TBI) is a common cause of mortality and disability in young age populations, particularly in children and adolescents. The objective of this systematic review and meta-analysis was to assess the prevalence of TBI among trauma patients in Ethiopia. Methods: A three-stage search strategy was conducted on PubMed/Medline, Science Direct and African Journals Online, and a grey literature search was conducted on Google Scholar. Data were analyzed with R version 3.6.1. Results: The pooled prevalence of TBI in Ethiopia was 20% (95% confidence interval (CI), 11–32). Subgroup analysis revealed that road traffic accident was the commonest mechanism of injury in Ethiopia at 21% (95% IC, 15–30), next was assault at 18% (95% CI, 5–48). Conclusion: This review shows a high prevalence of TBI among trauma patients in Ethiopia when compared with continental and global reports. Policymakers and stakeholders should work on regulatory laws on transportation; pre-hospital emergency medical care system is also in high demand.

Protocol registration: This review was registered in Prospero international prospective register of systematic reviews (CRD42020146643).
