Visualization analysis of research hotspots and development trends of hyperkalemia in hemodialysis patients
Objective To analyze the research hotspots and trends in the field of hyperkalemia in hemodialysis patients at home and abroad,and to provide reference for the research and prevention and control of hyperkalemia in hemodialysis patients.Methods China National Knowledge Infrastructure(CNKI)and Web of Science databases were searched by computer for literature about the hyperkalemia in hemodialysis patients published between January 1995 and January 2023.The included literature was analyzed using visualization analysis tools for visualization,including high-frequency keywords,keyword co-occurrence map,keyword emergence intensity and keyword time series prediction.Results A total of 10 275 articles were included.Among them,there were 10 036 articles from web of science and 239 articles from CNKI.The number of articles in this research field showed a trend of steady increase year by year.The United States was in a leading position in the research and development in this field,followed by China.At the same time,the research in this field presents the characteristics of multidisciplinary integration.The development trends of research hotspots in the next 5 years were risk and health education research.Conclusions The number of research articles related to hyperkalemia in hemodialysis patients is gradually increasing.Multidisciplinary approach and integration is a research hotspot and frontier in the development of hyperkalemia in hemodialysis patients both domestically and internationally.
