Neurosurgery-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.
PubMed, 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.
Of 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.
Neurosurgery 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.
神经外科专业的研究对于改善神经外科疾病患者的预后至关重要。尽管埃塞俄比亚神经外科疾病负担沉重，但人们对来自埃塞俄比亚的神经外科研究类型知之甚少。本范围综述的目的是评估 2001 年至 2021 年期间在同行评议期刊上发表的来自埃塞俄比亚的作者发表的神经外科研究的数量和类型。
在 PubMed、CINAHL、Embase 和 Scopus 中搜索 2001 年至 2021 年期间发表的埃塞俄比亚神经外科学文献。我们根据以下标准选择文章：文章必须 1）讨论神经外科领域的主题，2）关注埃塞俄比亚的临床实践和/或公共卫生。我们收集了研究创新性、研究设计以及临床与公共卫生研究的数据。分类变量的频率和百分比报告。所有分析均使用 Jamovi 软件进行。
在 362 项研究结果中，有 89 篇神经外科研究文章被纳入最终分析。在 89 篇文章中，病例报告/系列最为常见（28.7%），其次是回顾性队列研究（20.7%）和前瞻性队列研究（18.4%）。有 8 篇文献综述（9.2%）和 1 篇系统评价和荟萃分析（1.1%）。未发现随机对照试验。所有文章中，66 篇（75.9%）侧重于临床实践，21 篇（23.6%）与神经外科的公共卫生方面有关。42 篇文章（48.3%）仅由埃塞俄比亚作者撰写；37 篇文章（42.5%）涉及埃塞俄比亚作者与来自另一个国家的作者之间的合作，8 篇文章（9.2%）没有埃塞俄比亚作者。
尽管埃塞俄比亚神经外科疾病负担沉重，但神经外科研究却很少。病例报告/系列和队列研究仍然是主要研究方法，系统评价和随机对照试验很少。国际合作约占埃塞俄比亚神经外科研究成果的一半。应进一步发展研究支持和基础设施，以鼓励来自埃塞俄比亚的神经外科文章。
