BACKGROUND
In the global aging circumstances, the coexistence of multiple chronic diseases has become a common phenomenon of the elderly adults with chronic diseases, and the related research results of multiple chronic diseases in the elderly are gradually abundant. The analysis of research trends and hot spots in the field of multiple chronic diseases can provide references for relevant researchers to track cutting-edge information and facilitate further improvement of relevant research in this field.
OBJECTIVE
The purpose of this study is to conduct a comprehensive bibliometric analysis of the global research on multiple chronic diseases of the elderly in the past decade, and explore the research trends and hot spots in this field.
METHODS
Based on text mining technology and bibliometrics and other methods, the publications related to multiple chronic diseases of the elderly in Web of Science, PubMed, Scopus and other databases were used as research data. CiteSpace, PASW, BICOMB and other software were used to analyze and visualize the trend of number of publication, sources, authors, institutions, keywords and other aspects of publication, and three-dimensional strategic coordinate map and Sankey diagram were drawn to analyze the research trends and hot spots evolution in the field.
RESULTS
In the past ten years, the number of publications published in the field of senile multiple chronic diseases has increased exponentially, with an annual growth rate of 15.84%. Scholars have cooperated extensively, forming a number of cooperative groups. By clustering high-frequency keywords, five mainstream research hot spots are found. The data is divided into four time periods, and it is found that the evolution of hot spots is from less to more, from shallow to deep.
CONCLUSIONS
The research of senile multiple chronic diseases is in a rapid development stage. For the existing research results, basic research and method research has been relatively mature; The related research of physical comorbidities such as hypertension and diabetes, and psychiatric comorbidities such as depression and Alzheimer's disease are currently hot spots, which still need to be further explored. Emerging research topics related to comorbid diseases such as heart failure and stroke are potential hot spots.
