Objective To investigate the current status and development of electronic health records (EHR) at home and abroad to grasp the development trends of EHR, so as to point out the direction of the development and relevant research on EHR. Methods Based on the Web of Science citation database and the principle of bibliometrics, we analyzed the retrieved literature in aspects of publication date, language, country/region, institution, author, etc. Results A total of 1 262 eligible studies were identified. The number of articles on EHR increased rapidly from only 2 in 1995 to 218 in 2012. In terms of country/region, the United States ranked the top in all countries (763 articles, accounting for 60.46%). In terms of institution, Harvard University ranked the top (135 articles, accounting for 10.70%). In terms of journal, the Journal of the American Medical Informatics Association ranked the top (106 articles, accounting for 8.40%). In terms of authors, David W. Bates ranked the top (45 articles, accounting for 3.57%). In terms of subject type, health care sciences services and medical informatics were mainly focused on. Conclusion The research on EHR has become a global hot spot and relevant bibliometrics will contribute to the timely and correctly grasp the whole picture of its development trends and main research direction.
Objective To reveal the worldwide research status and hot topics of sleep apnea syndrome ( SAS) . Methods Articles were searched from Web of Science ( SCI) , Essential Science Indicator ( 2000 to 2010) database using sleep apnea syndrome or apnea as keywords. Retrieved documents were analyzed using the database with its own statistical functions and histcite software ( version 8.12. 16) .Results Since 1992 the international scientific papers on the SAS study showed a gradual upward trend.The United States is a world leader in this field. Recent research has focused on vascular endothelial barrier function and repair, oxidative stress, inflammation, cognitive function, special populations such as the elderlyor children patients with SAS. Conclusion Clinical researchers have paid more attention to SAS than before, but there are still many important issues unresolved.
Objective To conduct a bibliometric analysis of literature related to sleep apnea syndrome (SAS) during pregnancy, reveal research trends, and promote further development in this field. Methods A search was conducted in the Web of Science Core Collection for literature related to SAS during pregnancy, covering the period from the establishment of the database to July 25, 2024. HistCite and Excel were used to conduct a comprehensive analysis of the literature, including publication year, journal source, author, institution, country, and region. Results A total of 956 articles were included. Research on SAS during pregnancy had undergone an initial stage (1978-2009), a slow growth stage (2010-2020), and a rapid growth stage (2021 to present). The keyword with the highest frequency was “sleep”. The United States was the most active in this field, and the number of studies in China had significantly increased in recent years. High-yield authors mainly included Bourjeily G, O’Brien LM and Facco FL. The top five journals in terms of publication volume were Sleep Medicine, Journal of Clinical Sleep Medicine, Sleep and Breathing, Sleep, American Journal of Obstetrics and Gynecology. Conclusions Although significant progress has been made in the field of SAS during pregnancy, there are still research gaps in areas such as pathological mechanisms, diagnostic techniques, long-term impacts on mother and child, and treatment optimization. Research on SAS during pregnancy in China exhibits a trend of “increasing quantity but needing improvement in quality”.
