Worldwide research performance on telemedicine for newborns and neonatal intensive care units: A bibliometric and visualization study

Background Telemedicine uses videoconferencing technology to enable real-time audio and visual communication, linking on-site healthcare providers with specialists at remote locations. Over the past decade, telemedicine has grown significantly within the field of neonatology. This study seeks to deepen the understanding of telemedicine applications for newborns and neonatal intensive care units (NICUs) through a detailed bibliometric analysis.Methods Publications on telemedicine in newborns and NICUs from January 1, 2004, to October 22, 2024, were retrieved from the Web of Science Core Collection. Using Microsoft Excel, CiteSpace, the R package "bibliometrix," and VOSviewer, we analyzed the data to examine the number of publications, contributing countries/regions, institutions, authors, journals, references, and keywords.Results Since 2004, 1177 publications have been included, reflecting a rapid increase in research on telemedicine in newborns and NICUs over the past decade. These studies originated from 55 countries/regions and 139 institutions. The United States, the United Kingdom, and India were the primary contributors in terms of publication volume. Among the 405 authors analyzed, Jennifer L. Fang had the highest number of publications, while James P. Marcin received the most co-citations. BMC Pregnancy and Childbirth published the most articles, and Pediatrics had the highest citation count. The most frequently used keywords included "accuracy," "depression," "digital health," "mobile health," and "parents," highlighting key research areas. Emerging research frontiers such as "palliative care," "low-income populations," "artificial intelligence," and "parents with high-risk infants" indicate rapidly advancing topics in this field.Conclusions This study is the first to perform a comprehensive bibliometric analysis of publications on telemedicine in newborns and NICUs. In the previous 20 years, global interest in teleneonatology research has significantly increased. Our bibliometric findings offer valuable insights for researchers, helping them understand essential information, recognize current research hotspots, identify potential collaborators, and explore future research frontiers in this field.
