基于Web of Science数据库国内加速康复外科研究的文献计量学分析

Bibliometric analysis of domestic enhanced recovery after surgery studies based on Web of Science

目的通过文献计量学的方法探讨我国加速康复外科(ERAS)的研究现状和研究热点。方法基于Web of Science数据库,检索并筛选2000年1月1日—2020年12月31日我国学者发表的与ERAS相关的原始研究。分析年度发文量与引用量;作者、机构、省份分布;发表的杂志与引用的杂志;应用的手术与关键词;研究设计和证据等级。结果共纳入297篇文献,年度发文量和引用量均呈明显上升趋势;Wang为高发文量作者,Jiang为高发文量的通信作者,Kehlet为参考文献中的高被引作者;浙江大学、四川大学、南京大学为高发文量机构;江苏省、浙江省、四川省为高发文量省份;British Journal of Surgery为高被引杂志。ERAS最常应用在结直肠手术中,最频繁出现的关键词为"colorectal surgery""gastric cancer""laparoscopy";近年频繁出现的关键词有"total knee arthroplasty""lung cancer""length of stay""postoperative complications""nursing""elderly""quality of life"。最常见的研究设计为随机对照试验,其次为回顾性病例对照研究。已发表研究中以2级证据和4级证据最多,2级证据文献引用量显著高于4级证据文献,差异有统计学意义(P<0.01)。结论膝关节置换、肺手术、住院天数、术后并发症、护理、老年患者、生活质量等为近年来我国ERAS原始研究中高度关注的内容。未来应开展更多前瞻性、高证据等级的研究。

Objective To explore the research status and hotspots of enhanced recovery after surgery(ERAS)in China by means of bibliometrics.Methods Based on the Web of Science,the original researches related to ERAS published by Chinese scholars from January 1,2000 to December 31,2020 were retrieved and screened.The annual number of publications and citations,distribution of authors,institutions,provinces,journals published and cited,operations and keywords applied,study design,and level of evidence were analyzed.Results A total of 297 articles were included,and the number of annual publications and citations showed a significant upward trend.Wang was a high-volume author,and Jiang was a high-volume corresponding author,and Kehlet was a highly cited author in the bibliography.Zhejiang University,Sichuan University,and Nanjing University were high-volume institutions,and Jiangsu,Zhejiang,and Sichuan were high-volume provinces.British Journal of Surgery was a highly cited journal.ERAS was most commonly used in colorectal surgery,the most frequently occurring keywords were colorectal surgery,gastric cancer and laparoscopy.Key words that frequently appeared in recent years included total knee arthroplasty,lung cancer,length of stay,postoperative complications,nursing,elderly and quality of life.The most common study designs were randomized controlled trials,followed by retrospective case-control studies.Among the published studies,the second-level evidence and the fourth-level evidence were the most,and the number of citations of the second-level evidence was significantly higher than that of the fourth-level evidence,and the difference was statistically significant(P<0.01).Conclusions Knee replacement,lung surgery,length of stay,postoperative complications,nursing,elderly,quality of life and so on are the contents of high concern in the original research of ERAS in China in recent years.Prospective,high-level studies should be carried out in the future.
