Enhanced recovery after surgery (ERAS) protocol has been implemented in surgeries for more than 20 years, this study investigated the global states and hotspots of ERAS research.
Based on the Web of Science database, a bibliometric and visualized study of original ERAS research from 2000 to 2020 was performed, including the trends of publications and citations; distribution of countries, authors, institutions, sources; study design, level of evidence, served surgeries and surgical disciplines. Hotspots were revealed by research interests and keywords.
Within the field of original ERAS research, there was a rising trend in annual publications and citations. The USA was the greatest contributor. Kehlet, H, University of Copenhagen were the most influential author and institution, respectively. British Journal of Surgery and Annals of Surgery were the most cited journals. Though there were more prospective designs, more than half of the studies presented level IV evidence and had fewer citations and citation densities compared to that of level II and level III. ERAS protocol was overwhelmingly implemented in colorectal surgeries. Most studies focused on elements of ERAS, the top three research interests were "length of stay," "pain management," and "complications." In recent years, bariatric surgery, compliance with ERAS, and feasibility in the elderly were new hotspots.
Revealing the global states and hotspots can help researchers better understand the trends in ERAS research. The USA was the greatest contributor to ERAS research. Kehlet, H, was the most influential author in the field. Bariatric surgery, compliance with ERAS, and feasibility in the elderly represent the new trend of ERAS research. Most of the ERAS research had a low evidence levels, studies with high-level evidence are still required in this field.
术后加速康复（ERAS）方案已在外科手术中应用20多年，本研究调查了ERAS研究的全球状况和热点。
基于科学网数据库，对2000年至2020年ERAS原始研究进行文献计量和可视化研究，包括出版物和引文趋势；国家、作者、机构、来源分布；研究设计、证据水平、所服务的手术和外科学科。通过研究兴趣和关键词揭示热点。
在ERAS原始研究领域，年度出版物和引文呈上升趋势。美国是最大贡献者。哥本哈根大学的赫尔特·H是最有影响力的作者和机构。《英国外科杂志》和《外科学年鉴》是被引用最多的期刊。尽管前瞻性设计较多，但超过一半的研究提供的是IV级证据，与II级和III级证据相比，其引文和引文密度较少。ERAS方案在结直肠手术中得到广泛应用。大多数研究集中在ERAS的要素上，前三大研究兴趣是“住院时间”“疼痛管理”和“并发症”。近年来，减重手术、ERAS依从性和老年人中的可行性成为新热点。
揭示全球状况和热点有助于研究人员更好地了解ERAS研究趋势。美国是ERAS研究的最大贡献者。赫尔特·H是该领域最有影响力的作者。减重手术、ERAS依从性和老年人中的可行性代表了ERAS研究的新趋势。大多数ERAS研究证据水平较低，该领域仍需要高水平证据的研究。
