Methods The articles published in the China National Knowledge Infrastructure （CNKI） database on IECD before April 2017 were searched. Microsoft Excel and the computer program were used to construct keywords frequency lists and correlation matrix. SPSS 18.0 software was used for hierarchical clustering. Results A total of 546 articles were included, 59 high frequency keywords were extracted, and 8 hotspots in this field were summarized by cluster analysis. Conclusion To some extent, 8 hotspots in this field reflect the trends of this field and could provide some reference for clinical practice.
