目的 通過關鍵詞共現分析和作者共現分析的方式，研究國內外循證醫學教育領域的研究熱點、學科分支和發展趨勢。 方法 通過檢索中國學術期刊數據庫（CNKI）和Medline數據庫，分別收集相關研究文獻，并提取關鍵詞詞頻、作者發文數、核心期刊和核心研究單位，對核心關鍵詞和核心發文作者建立共現矩陣，使用Ucinet繪制可視化網絡圖。 結果 成功得到核心關鍵詞和核心作者可視化網絡。中文可視化網絡包括“循證醫學”、“護理”、“教育”、“教學”4個方面，英文可視化網絡包括“evidence-based medicine”、“nursing”、“education”、“organization amp; administration”4個方面，國內外該學科發展趨勢相似。國內循證醫學教育以四川大學為核心，合作網絡較大。同時國內核心期刊與國外側重點不同。 結論 國內循證醫學教育研究領域總體發展趨勢良好，在醫學教育中起著極為重要的作用。Objective To built visualized networks of evidence-based medical education in and out of China by using co-occurrence analysis of key words and authors. Methods We searched the China National Knowledge Infrastructure (CNKI) database in Chinese and Medline database in English, collecting the related articles, and took out the core key words, core authors and core administrations. Then we built the matrix of key words and authors, and finally finished visualized network by Ucinet. Results We successfully obtained the visualization of this subject. Chinese network contained four parts: “evidence-based medicine”, “nursing”, “education” and “teaching”; while English network also contained four parts: “evidence-based medicine”, “nursing”, “education”, “organization” and “administration”. In China, Sichuan University located in the center of the network of authors, and also leading in the administrations. The network of authors in China showed a larger cooperation than overseas. And the core-periodicals had different emphases. Conclusion The evidence-based medical education develops well in China, and plays an important role in the medical education.
【摘要】 目的 通過關鍵詞共現分析和作者共現分析的方式，研究國內外循證心血管領域的研究熱點、學科分支和發展趨勢。 方法 通過檢索中國生物醫學數據庫和Medline數據庫，分別收集相關研究文獻，并提取關鍵詞詞頻、作者發文數和核心研究單位，對核心關鍵詞和核心發文作者建立共現矩陣，使用Ucinet繪制可視化網絡圖。 結果 成功得到核心關鍵詞和核心作者可視化網絡。中文可視化網絡包括循證醫學、治療和護理3個方面，英文可視化網絡包括evidence-based medicine、therapy和treatment outcome 3個方面。而在作者合作可視化網絡中，國內作者合作關系較為松散，合作團體較小，國外作者合作關系較為緊密，合作團體較大。國內核心研究機構分布于循證研究重點高校，國外則以發達國家為主。 結論 國內循證心血管研究領域總體發展趨勢較好，但較國外相比仍存在一些不足，需要進一步加強重點研究，調整研究規劃。【Abstract】 Objective To research on the hot issues, branch system and development trend of evidence-based cardiovascular medicine in and out of china by using co-word analysis of keywords and authors. Methods By Searching the CBM database in Chinese and Medline database in English, we collected the related articles and picked out the frequency of keywords, authors and core administrations, and built the matrix of keywords and authors. Finally we completed the visualized network by Ucinet. Results We successfully obtained the visualization of this subject. Chinese network contained three parts: evidence-based medicine, therapy and nursing, while English network also contained three parts: evidence-based medicine, therapy and treatment outcome. In the authors′ visualized network, Chinese authors had less cooperation and looser relationship compared with their counterparts overseas. The core administrations in china located in outstanding universities, and developed countries had the dominated roles in the world. Conclusions The development trend of evidence-based cardiovascular medicine in china is good, but still has some limitations compared with overseas studies. More emphasis should be put on strengthening core-area researching and research plan adjustment.
