摘要
目的：由于临床上担心有限的医疗资源分配会影响医生的研究生产力，本研究探讨了经济合作与发展组织（OECD）国家眼科研究文献计量指数与国家经济指标之间的关联：方法：在 Scimago 期刊和国家排名中搜索 1996 年至 2019 年 OECD 国家的眼科研究生产率数据。文献计量指数包括：文献数量、可引用文献数量和百分比、被引次数、每篇文献被引次数和H指数。各国的最新经济指标（人均国内生产总值[GDP]、卫生支出占GDP的百分比（卫生支出）、国内研究与发展总支出占GDP的百分比[GERD]）从世界银行和经合组织网站收集。对经济指标和文献计量指标之间的相关性进行了分析，并进行了多元线性回归分析：在分析的 267 444 篇文献中，相关性分析发现卫生支出与 H 指数之间存在很强的相关性（r = 0.711，p r = 0.589，p r = 0.593，p r = 0.673，p r = 0.564，p 结论：这项研究表明，文献计量学指标与卫生支出之间存在正相关：本研究表明，在经合组织国家中，眼科研究的文献计量指标与经济因素（尤其是医疗支出）之间存在正相关关系。我们的研究结果表明，国内卫生投资有利于提高眼科学领域的学术生产力。
Academic Productivity in Ophthalmology and Its Correlation to National Economic Indicators Among the OECD Countries: A Bibliometric Analysis.
Purpose: Prompted by the clinical concern that limited healthcare resources allocation affects physicians' research productivity, this study examines the association between bibliometric indices of ophthalmologic research and national economic indicators in Organisation for Economic Co-operation and Development (OECD) countries.
Methods: The Scimago Journal and Country rank source was searched for research productivity data in ophthalmology among OECD countries between 1996 and 2019. Bibliometric indices included: documents number, number and percent of citable documents, citations number, citations per document, and H-index. The updated economic indicators of each country (gross domestic product [GDP] per capita, health spending as percent of GDP (health expenditure), gross domestic expenditure on research, and development as percent of GDP [GERD]) were collected from the World Bank and the OECD websites. Correlation between economic and bibliometric metrics and multivariate linear regression analyses were performed.
Results: Among 267,444 documents analyzed, correlation analysis found a strong correlation between health expenditure and H index (r = 0.711, p < 0.001); a moderate correlation between health expenditure and documents number (r = 0.589, p < 0.001), number of citable document (r = 0.593, p < 0.001) and citations number (r = 0.673, p < 0.001); and a moderate correlation between GERD and H index (r = 0.564, p < 0.001). Multivariate regression analysis controlling for economic factors, population and language showed the independent association of these parameters with bibliometric indices.
Conclusions: This study demonstrates a positive correlation between bibliometric indicators of ophthalmology research and economic factors, particularly health expenditure, among the OECD countries. Our results suggest an advantage of domestic investment in health to expand academic productivity in the field of ophthalmology.
期刊介绍：
Ophthalmic Epidemiology is dedicated to the publication of original research into eye and vision health in the fields of epidemiology, public health and the prevention of blindness. Ophthalmic Epidemiology publishes editorials, original research reports, systematic reviews and meta-analysis articles, brief communications and letters to the editor on all subjects related to ophthalmic epidemiology. A broad range of topics is suitable, such as: evaluating the risk of ocular diseases, general and specific study designs, screening program implementation and evaluation, eye health care access, delivery and outcomes, therapeutic efficacy or effectiveness, disease prognosis and quality of life, cost-benefit analysis, biostatistical theory and risk factor analysis. We are looking to expand our engagement with reports of international interest, including those regarding problems affecting developing countries, although reports from all over the world potentially are suitable. Clinical case reports, small case series (not enough for a cohort analysis) articles and animal research reports are not appropriate for this journal.
