We hypothesized that there may be significant differences between academic productivity of the vascular training programs in the United States (US) and Europe. In an effort to explore this theory, we reviewed the number of vascular publications listed in PubMed from 2010 to 2015 for US and European directors in vascular surgery.
The list of program directors from the Association of Program Directors in Vascular Surgery (APDVS) and the European Union of Medical Specialists (EUMS) were queried for the names of the directors of vascular surgical training programs at the end of 2015. PubMed listed 5,474 citations published from 2010 to 2015. Three thousand five hundred sixty-one were from Europe while 1,912 were from the US. UK and German programs did not list their directors' names in the EUMS website and were thus not included in the European data.
The average number of citations in PubMed per program director was 2.36 per year. In Europe, each of the 273 program directors averaged 2.17 publications per year, whereas each of the 114 US program directors averaged 2.80 publications per year (P = 0.37). Journal of Vascular Surgery (JVS) publications made up 24.0% (12.7% in Europe and 45.0% in the US). In the US, the top third produced 69% of the publications and 77% of the JVS publications, whereas in Europe, the top third produced 87% of the publications and 98% of the JVS publications. In the US, 5 program directors (4.4%) had no publications and 21 (18.4%) had no JVS publications. In Europe, 82 program directors (30.0%) had no publications, whereas 180 (65.9%) had no JVS publications. Abstracts were categorized by topic for comparison.
In both Europe and the US, the top third produced more than two-thirds of the publications, with the disparity being even more pronounced in Europe where the top third produced almost 90% of the total publications. Comparing the topics of the publications from Europe and the US, it was found that the US program directors published a great deal more on Endovenous Lower Extremity, Open Lower Extremity, Education, thoracic endovascular aortic repair, Open Carotid, and Endo Venous, whereas their European counterparts published more in the areas of Vascular Medicine, Replies, and Not Vascular.
我们推测美国和欧洲的血管外科培训项目在学术产出方面可能存在显著差异。为了探究这一理论，我们查阅了2010年至2015年美国和欧洲血管外科主任在PubMed上列出的血管相关出版物数量。
查询血管外科项目主任协会（APDVS）和欧洲医学专家联盟（EUMS）的项目主任名单，获取2015年末血管外科培训项目主任的姓名。PubMed列出了2010年至2015年发表的5474条引用文献。其中3561条来自欧洲，1912条来自美国。英国和德国的项目未在EUMS网站上列出其主任姓名，因此未纳入欧洲数据。
每位项目主任在PubMed上每年的平均引用次数为2.36次。在欧洲，273位项目主任每人每年平均发表2.17篇论文，而美国的114位项目主任每人每年平均发表2.80篇论文（P = 0.37）。《血管外科杂志》（JVS）的出版物占24.0%（欧洲为12.7%，美国为45.0%）。在美国，排名前三分之一的项目主任发表了69%的论文以及77%的JVS论文，而在欧洲，排名前三分之一的项目主任发表了87%的论文以及98%的JVS论文。在美国，5位项目主任（4.4%）没有发表论文，21位（18.4%）没有发表JVS论文。在欧洲，82位项目主任（30.0%）没有发表论文，而180位（65.9%）没有发表JVS论文。对摘要按主题进行分类以作比较。
在美国和欧洲，排名前三分之一的项目主任发表的论文均超过总数的三分之二，在欧洲这种差距更为明显，排名前三分之一的项目主任发表的论文几乎占总数的90%。比较美国和欧洲出版物的主题发现，美国项目主任在下肢静脉内治疗、下肢开放手术、教育、胸主动脉腔内修复、颈动脉开放手术和静脉内治疗等方面发表的论文要多得多，而欧洲同行在血管医学、回应和非血管领域发表的论文更多。
