Hundred Most Cited Articles in Perioperative Neurocognitive Disorder: A Bibliometric Analysis

Abstract

\n Background: In line with aging populations and increased application of anesthesia and surgery, perioperative neurocognitive disorder (PND) has received growing attention worldwide. Considerable research into PND is being conducted; however, the quantity and quality of such research have not been reported. Through a retrospective bibliometric analysis, this study aimed to identify and characterize the top 100 cited publications on PND. Methods: We searched the Web of Science database to find the top 100 cited articles focusing on PND. We collected bibliographic information, including year of publication, country of origin, article type, published journal, citation count, and authorship. To determine changes with time, we compared older and newer articles. Results: The top 100 cited articles were published between 1955 and 2016; the number of citations ranged from 111 to 1248. The United States had the most published papers; clinical trials were the most common article type. The specialty journals of Anesthesiology and Anesthesia & Analgesia were the two most cited journals. Newer papers had a comparable number of citations to older articles, but the former had higher citation rates, greater funding disclosures, more focus on basic research, and more open access publications. Conclusions: This study provides a comprehensive overview of the most cited articles and highlights the increasing attention on PND. High-quality clinical trials with a greater journal impact factor received more citations. However, there has been growth in the number of basic science studies as an area of research with respect to the pathogenesis of PND.
