2014-2023年国内外小儿骨科多中心研究的文献计量学分析

Global advances of pediatric orthopedics multi-center clinical researches from 2014 to 2023

目的使用文献计量学方法分析国内外小儿骨科多中心研究论文发表的现状及热点。方法检索中国知网(China National Knowledge Infrastructure,CNKI)、万方医学网、维普数据库和Web of Science(WOS)中的小儿骨科多中心研究相关中文及外文文献,检索时限为2014年1月1日至2023年12月30日。采用Microsoft Excel和CiteSpace进行数据处理,对纳入文献的时间分布、期刊分布、机构分布、国家分布以及关键词等进行统计及可视化分析。结果共纳入文献846篇,其中外文文献716篇、中文文献130篇;美国发文量最高(387篇)。《中华小儿外科杂志》(15篇)和Journal of Pediatric Orthopaedics(119篇)分别是国内、国外刊登小儿骨科多中心研究论文最多的期刊。中文文献关键词主要被聚类为"儿童""外科手术""超声检查""三维成像""内固定器"5个簇;外文文献关键词主要聚类为developmental dysplasia of the hip,natural history,adult spinal deformity,avascular necrosis等13个关键词簇。关键词突现分析表明,当前国内研究的热点在于治疗结果、危险因素、超声检查等方面,国外研究的热点在于早发性脊柱侧凸、诊断、骨病学等方面。结论小儿骨科多中心研究近10年来主要关注点在于手术治疗、特殊疾病、预后结局和诊断等方面,美国在该领域发文最多,中国小儿骨科多中心研究逐渐获得国际认可,未来应继续加强多层次、全方位的科研合作,进一步提高小儿骨科多中心研究的质量。

Objective To employ bibliometric methods to explore current status and hotspots of pediatric orthopedic multicenter research publications globally.Methods A comprehensive database search was conducted in China National Knowledge Infrastructure(CNKI),Wanfang Medical Database,China Science and Technology Journal Database and Web of Science for the relevant articles published from January 1,2014,to December 30,2023.Raw data were organized and analyzed by Microsoft Excel and CiteSpace,focusing on the distribution of publications over time,across journals,institutions,countries and keywords.Results A total of 846 articles were retrieved,including 716 in English and 130 in Chinese;the United States(387)had the highest number of publications.Chinese Journal of Pediatric Surgery(15)and Journal of Pediatric Orthopaedics(119)were the most prolific journals.Chinese keywords were clustered into five groups of"children,""surgical procedures,""ultrasound examination,""three-dimensional imaging"and"internal fixators";international keywords formed thirteen clusters,including"developmental dysplasia of the hip"and"adult spinal deformity."Keyword burst analysis highlighted domestic hotspots in treatment outcomes,risk factors and ultrasound examination,whereas international hotspots included early-onset scoliosis,diagnostics and orthopedics.Conclusions Over the past decade,pediatric orthopedic multicenter researches have primarily focused upon surgical treatments,specific diseases,prognosis and diagnostics.The United States is a leading contributor while Chinese researches are gaining international recognition.Future efforts should emphasize multi-level comprehensive research collaborations to enhance the quality of pediatric orthopedic multicenter researches.
