The Global States and Hotspots of ERAS Research From 2000 to 2020: A Bibliometric and Visualized Study

Abstract

BackgroundEnhanced 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.MethodsBased 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.ResultsWithin 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.ConclusionRevealing 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.

A Scoping review of Enhanced Recovery After Surgery (ERAS), protocol implementation, and its impact on surgical outcomes and healthcare systems in Africa

“…Despite using an inclusive and comprehensive search strategy the number of existing studies on the implementation of ERAS protocols in Africa is very low, as we were only able to nd a few studies (n = 15) and they were limited to certain geographical locations, as most of these studies were conducted in Egypt (n = 10) and South Africa (n = 4). This nding is also consistent with a study of the global distribution of ERAS research, which found that most studies have been conducted in high-income countries (11). Furthermore, the implementation efforts were mostly in obstetric and gynecological procedures (n = 7).…”

“…However, the evidence on the implementation of ERAS practice in Africa is very limited (11), and most reports from the region are from small-scale studies or anecdotal reports. Additionally, resource constraints may further hinder the widespread implementation of ERAS in this region.…”

Patient characteristics and procedural variables are associated with length of stay and hospital cost among unilateral primary total hip arthroplasty patients: a single-center retrospective cohort study

“…The postoperative patients then received personally tailored rehabilitation services from the rehabilitation experts within our department, rather than transferring to the rehabilitation department or hospital. Of note, per our standard protocol, we applied a conventional rehabilitation program for these patients, instead of the Enhanced Recovery After Surgery (ERAS) [ 12 ].…”
