BackgroundNeurosurgery-specific research plays a critical role in improving outcomes in patients with neurosurgical diseases. Despite the high burden of neurosurgical diseases in Ethiopia, little is known about types of neurosurgical research from Ethiopia. The goal of this scoping review is to assess the quantity and types of neurosurgical research published in peer-reviewed journals by authors from Ethiopia.MethodsPubMed, CINAHL, Embase, and Scopus were searched for Ethiopian neurosurgery literature published from 2001 to 2021. We selected articles based on the following criteria: articles must 1) discuss topics within neurosurgery and 2) focus on clinical practice and/or public health in Ethiopia. We collected data on research originality, study designs, and clinical versus public health research. The frequencies and percentages of categorical variables were reported. All analyses were conducted using Jamovi software.ResultsOf the 362 results, 89 neurosurgical research articles were included in the final analysis. Of the 89 articles, case reports/series were most common (28.7%), followed by retrospective cohort (20.7%) and prospective cohort studies (18.4%). There were 8 literature reviews (9.2%) and 1 systematic review and meta-analysis (1.1%). No randomized controlled trial was found. Of all articles, 66 (75.9%) focused on clinical practice, and 21 (23.6%) were related to the public health aspect of neurosurgery. Forty-two articles (48.3%) included authors only from Ethiopia; 37 articles (42.5%) involved collaboration between Ethiopian and authors from another country, and 8 articles (9.2%) did not have Ethiopian authors.ConclusionsNeurosurgery research from Ethiopia is lacking, despite its high disease burden. Case reports/series and cohort studies remain the mainstay, with few systematic reviews and no randomized controlled trial. International collaboration accounts for approximately half of Ethiopian neurosurgery research output. Further research support and infrastructure should be developed to encourage neurosurgery articles from Ethiopia.Copyright © 2022 Elsevier Inc. All rights reserved.
