High-quality research is fundamental to the advancement of surgical practice. Currently, there is no quantitative assessment of the research output of vascular surgeons in Australia and New Zealand. By conducting this bibliometric analysis, we aim to provide an objective representation of the trends in vascular surgery and guide future research.
A list of all current vascular surgeons in Australia and New Zealand was compiled from the Royal Australasian College of Surgeons 'Find a Surgeon' website tool and correlated with the Australia and New Zealand Society for Vascular Surgery database. A Scopus search of each surgeon's author profile over the last 20 years was conducted.
In total, 2120 articles were published by 208 Australasian vascular surgeons between 1998 and July 2018, with an overall increase in publications over time. Audits or case series were the most published type of study and only 8% of the publications were of high-level evidence. The most popular topics were thoracoabdominal aortic pathologies (24%), followed by peripheral arterial disease (15%). Chronological analysis illustrates an increasing volume of peripheral arterial disease research over time and there is a clear trend towards more endovascular and hybrid surgery publications. The top 10 (5%) highest publishing authors by h-index account for 41% of all publications and 49% of all citations and are also responsible for producing significantly more high-level evidence research.
Australasian vascular surgeons have made a significant contribution to medical research. However, the majority of these articles are of low-level evidence. In this time, there has been an increasing number of publications on endovascular and hybrid surgery in keeping with the trend in clinical practice. These areas, as well as research regarding peripheral arterial disease, show potential for high-evidence research in the future.
高质量研究是外科实践进步的基础。目前，澳大利亚和新西兰血管外科医生的研究产出尚无定量评估。通过开展这项文献计量分析，我们旨在客观呈现血管外科的发展趋势并指导未来研究。
从澳大利亚皇家外科学院的“查找外科医生”网站工具中编制出澳大利亚和新西兰所有现任血管外科医生的名单，并与澳大利亚和新西兰血管外科学会数据库进行关联。对每位外科医生在过去20年的作者简介进行了Scopus检索。
1998年至2018年7月期间，208名澳大利亚和新西兰血管外科医生共发表了2120篇文章，总体发文量随时间呈上升趋势。审计或病例系列是发表最多的研究类型，只有8%的出版物具有高水平证据。最热门的主题是胸腹主动脉病变（24%），其次是外周动脉疾病（15%）。按时间顺序分析表明，外周动脉疾病研究的数量随时间不断增加，并且血管内手术和杂交手术出版物有明显增多的趋势。按h指数排名前10（占5%）的高产作者发表的文章占所有出版物的41%，占所有引用的49%，并且他们发表的高水平证据研究也显著更多。
澳大利亚和新西兰的血管外科医生为医学研究做出了重大贡献。然而，这些文章大多证据水平较低。在此期间，与临床实践趋势一致，血管内手术和杂交手术的出版物数量不断增加。这些领域以及外周动脉疾病的研究在未来显示出进行高证据研究的潜力。
