Objective Nurse practitioners (NPs) have drawn significant attention recently and played a major role in healthcare. We aim to find the evaluation of NPs through published studies and then visualize the research status and hotspots in this field. Methods All data came from the Web of Science Core Collection, and the data were counted and entered into Excel 2016. The key documents nodes were excavated by analyzing the knowledge network map using CiteSpaceV software. In this study, these nodes of “author, country, institution, keyword, co-citation (reference\cited-author\cited-journal), and grant” were harvested for analysis and comparison. Results A total of 4912 records, which were published between 2007 and 2018 and pertained to NPs, were retrieved from the Web of Science Core Collection database (WoSCC) from a diversity of languages. The total and the annual number of publications and citations of these continually increased over time. Most publications were in 2018 (618 records). This study involved 8241 authors located in 98 countries and 4557 institutions totally. The United States (2737 records) and the University of Michigan (90 records) dominated in publication frequency. There are 902 journals and 2449 articles with funding support that have been analyzed. Most articles were from JAMA: The Journal of the American Medical Association (1386, IF = 47.661), followed by the Journal of Advanced Nursing (1359, IF = 2.267), and The New England Journal of Medicine (1109, IF = 79.258). The reference “The Role of Nurse Practitioners in Reinventing Primary Care” was co-cited most frequently, which revealed it as the highest landmark article in NP. The top-ranked keyword was “Care,” other than “Nurse practitioner,” which has an ultra-high frequency. Some of the high-frequency keywords represent the significant direction of NPs. Conclusions NPs are at the crux of health-care delivery and play an important role in providing high-quality nursing. Publications on NPs in WoSCC have increased notably during the recent years, and have appeared in some journals that have a high impact factor. Research frontiers and developmental trends were revealed by the analysis in this study, which can be used to forecast future research developments in NPs and taken as a reference to choose the right directions by subsequent researchers who wish to use these results. However, the grant support from administration or research institutions is still in need of improvement and the scope of research in NPs should be broadened in the future. |
