The top 100 most cited papers in insomnia: A bibliometric analysis

Abstract

ObjectiveThe number of citations to a paper represents the weight of that work in a particular area of interest. Several highly cited papers are listed in the bibliometric analysis. This study aimed to identify and analyze the 100 most cited papers in insomnia research that might appeal to researchers and clinicians.MethodsWe reviewed the Web of Science (WOS) Core Collection database to identify articles from 1985 to 24 March 2022. The R bibliometric package was used to further analyze citation counts, authors, year of publication, source journal, geographical origin, subject, article type, and level of evidence. Word co-occurrence in 100 articles was visualized using VOS viewer software.ResultsA total of 44,654 manuscripts were searched on the Web of Science. Between 2001 and 2021, the top 100 influential manuscripts were published, with a total citation frequency of 38,463. The top countries and institutions contributing to the field were the U.S. and Duke University. Morin C.M. was the most productive author, ranking first in citations. Sleep had the highest number of manuscripts published in the top 100 (n = 31), followed by Sleep Medicine Reviews (n = 9). The most cited manuscript (Bastien et al., Sleep Medicine, 2001; 3,384 citations) reported clinical validation of the Insomnia Severity Index (ISI) as a brief screening indicator for insomnia and as an outcome indicator for treatment studies. Co-occurrence analyses suggest that psychiatric disorders combined with insomnia and cognitive behavioral therapy remain future research trends.ConclusionThis study provides a detailed list of the most cited articles on insomnia. The analysis provides researchers and clinicians with a detailed overview of the most cited papers on insomnia over the past two decades. Notably, COVID-19, anxiety, depression, CBT, and sleep microstructure are potential areas of focus for future research.

In response to Impact of Insomnia on Hypoglossal Nerve Stimulation Outcomes in the ADHERE Registry

“…1 Although the ISI has not been validated in OSA samples, it was utilized in several hundred studies and cited 3400 times from 2001 to 2022 in diverse study populations. [2][3][4] Its popularity is reflected by ease of administration and ability to measure both nocturnal insomnia (questions 1-3) and resultant daytime impairment (questions 4-7). However, given shared symptoms between OSA and insomnia resulting in poor sleep quality, the ISI can be falsely elevated when patients experience daytime impairment due to OSA without significant nocturnal insomnia.…”
