全球心血管疾病学术影响力评价(CAPE)体系的方法探索

Methodological Exploration for Global Cardiovascular Academic Performance Evaluation(CAPE)System

目的:构建全球心血管疾病学术影响力评价(Cardiovascular Academic Performance Evaluation,CAPE)体系,并对全球医疗机构心血管疾病学术影响力进行排名。方法:由心血管疾病领域人员和图书情报人员提取医学主题词表(MeSH)、Embase同义词表、国际疾病分类(ICD)中心血管疾病相关术语,建立心血管术语词表(即阜外词表),设定缺血性心脏病、高血压、血管疾病、心律失常、肺血管疾病、心力衰竭、先天性心脏病、心肌病和瓣膜性心脏病等9个亚学科,实现亚学科分类、心血管术语词、入口词的映射。检索Web of Science、PubMed、Scopus数据库2016年1月1日至2022年12月31日的心血管领域论文,并对元数据进行去重融合;应用阜外词表对论文中主题词、题目、关键词、摘要等4个位置的内容进行检索匹配,生成论文“位置-心血管术语词-频次”的信息表,计算每一篇论文心血管学科相关度积分及亚学科积分。对论文的机构名、学者名进行规范化清洗,基于心血管强相关(相关度积分≥4分)原创性论文开展全球心血管疾病领域学术影响力的评价。针对全国医疗机构(心血管)的科技评价,还采集了国家自然科学基金项目、授权发明专利、获奖成果、科研平台、注册试验[国家药品监督管理局药品审评中心(CDE)药物临床试验登记数据]等数据。结果:检索到全球2016~2022年心血管领域论文1545103篇,剔除摘要、书籍、传记、新闻、视频、音频、撤稿、更正声明后为1178019篇,使用阜外词表标引“心血管强相关”论文518058篇。还采集到11143项心血管相关国家自然科学基金项目、19382项心血管相关有效授权发明专利、103项心血管相关国家级获奖成果、24个心血管相关国家科研平台、2084项CDE心血管相关药物临床试验登记等数据。经组织心血管疾病及其亚学科专家团队针对各自亚学科论文进行核对和验证,改进学科分类规则,最终锁定11项指标构建了心血管疾病和9个亚学科领域的综合评价指标体系。2016~2022年,中国发表心血管疾病研究论文数量增幅为123.5%,共发表约7.68万篇,平均每天约30篇,仅次于美国(约11.41万篇),居世界第二位。但中国期刊引证报告(JCR)分区和中国科学院分区论文占比仅居世界第八位。在2020~2022年全球医疗机构心血管原创研究论文影响力综合评估中,仅2家中国医疗机构进入前20名。结论:CAPE项目基于2016~2022年多源数据基础,首次探索建立了心血管领域机构学术影响力综合评价指标体系。

Objectives:To establish a comprehensive system of Cardiovascular Academic Performance Evaluation(CAPE)and rank global TOP100 medical institutions in the fields of cardiovascular diseases(CVD).Methods:CVD-related terms were extracted from Medical Subject Headings(MeSH),Embase thesaurus(EMtrees)and International Classification of Diseases(ICD)by CVD-related professionals,as well as by librarians and information professionals.Terminology databases(named as Fuwai Subject Headings)were established,and nine sub-disciplines were proposed,including ischemic heart diseases,hypertension,vascular diseases,arrhythmia,pulmonary vascular diseases,heart failure,congenital heart diseases,cardiomyopathy,and valvular heart diseases.The mapping patterns of sub-discipline,cardiovascular terminology and entry terms were pre-defined.The CVD-related research literature published from January 1,2016 to December 31,2022 were retrieved from Web of Science,PubMed and Scopus.Based on this,metadata were fused and duplicates were excluded.Fuwai Subject Headings were searched and matched into four respects for each literature,including subject words,titles,keywords,and abstracts,which was used to generate an information table of“Position—CVD terminology—Frequency”,and to calculate CVD correlation scores and sub-discipline scores.We standardized the names of medical institutions and scholars,and make a ranking system for CAPE based on original articles with strong cardiovascular correlation(correlation score≥4).When evaluating the science and technological performance for Chinese hospitals in cardiovascular diseases,National Natural Science Foundation Projects,authorized invention patents,prize achievements,research platforms,and registered data of drug clinical trials in Center for Drug Evaluation(CDE)were considered besides research papers.Results:During 2016 and 2022,1545103 CVD research literatures were found worldwide.After excluding meeting abstracts,books,biographies,news,videos,audio texts,retracted publications,and corrections,1178019 CVD research literatures were further evaluated.518058 literatures were indexed as“strongly correlated to CVD”using Fuwai Subject Headings.Besides papers,other data sources were also collected,including 11143 CVD-related Natural Science Foundation Projects,19382 CVD-related effective authorized invention patents,103 CVD-related national prize achievements,24 CVD-related national research platforms,and 2084 CDE registered data of CVD-related drug clinical trials.Research teams from nine sub-disciplines reviewed and validated research literature in respective fields,and classification rules of corresponding sub-disciplines were created and improved based on their opinions.Finally,eleven individual indexes were chosen to construct CAPE system for ranking global TOP100 medical institutions in overall CVD field and TOP30 in nine sub-disciplines.From 2016 to 2022,the number of cardiovascular disease research papers published by Chinese institutes has increased by 123.5%,with a total of approximately 76.8 thousands papers published(about 30 papers per day on average),ranked the second under the United States(approximately 114.1 thousands papers).However,the proportion of papers published by the Chinese Journal Citation Reports(JCR)and the Chinese Academy of Sciences only ranked eighth in the world.In the comprehensive academic performance of original cardiovascular research papers in global hospitals from 2020 to 2022,only two Chinese medical institutions ranked in the TOP20 as evaluated by CAPE system.Conclusions:Based on multi-source data from 2016 to 2022,CAPE initiated to establish a cardiovascular academic performance evaluation system.
