Objective: To analyze and evaluate the utilization of evidence-based medical research in our country as of October 2005. Methods: Bibliometrics and Citation Analysis. Results: A total of 561 articles were cited by 353 journals in China for 1752 articles, with an annual average of 109.5 articles cited and over 21% cited in core journals. Peaks were quoted in 1998-2002 and reached their peak in 2000. Of the cited citations, there were 91 species with 280 or more citations, and 66.30% cited citations appeared in 32.50% of the journals, that is 1/3 of the journals contributed 2/3 citations. 353 periodicals are involved in the source literature, and 52 journals are cited more than 10 times. Among the journals in the cited journals and source literature, medical journals account for a large proportion of journals. High-frequency cited documents mainly for the basic theory of evidence-based medicine and related concepts introduced literature. Conclusion: The use of evidence-based medical literature is mainly in the field of basic theoretical research, with a certain number of core authors and major research institutes. Intelligence journals occupy a large proportion of non-medical journals and library and librarians are active in evidence-based medicine research.
