四种循证医学数据库比较分析

目的比较分析4种知名循证医学数据库的优缺点，为我国循证医学数据库的建设提供参考。方法运用文献分析法及网页搜索综合分析UpToDate、MDConsult、ClinicEvidence和DynaMed数据库的经营理念、编辑流程、个性化服务等特点。结果①从建立时间来看，UpToDate建立于1992年，是最早建立的循证医学数据库；②从经营理念来看，4个数据库都以整合当前针对某一临床主题的所有高质量证据、帮助临床医生形成当前最合理的决策建议为宗旨；⑧从编辑流程来看，ClinicalEvidence的证据纳入经过18个步骤，相比其他3个数据库更加严谨；④在更新速度方面，DynaMed每天更新，在4个数据库中更新最快。结论建设一个成熟的循证医学数据库需要强大的方法学团队和雄厚的资金支持，以及大量的全文服务。国内循证医学数据库的建设应该积极吸取国外经验，建设自己的方法学团队，更重要的是融入国内的特色。

Comparison and Analysis on Four Evidence-Based Medicine Databases

Objective To study and analyze both merits and demerits of 4 famous foreign evidence-based medicine databases, so as to provide references for the development of Chinese evidence-based medicine databases. Methods By means of document analysis and web search, the databases including UpToDate, MD Consult, Clinical Evidence and DynaMed were comprehensively analyzed from the following aspects： management ideas, editing process, personalized services and so on. Results a） Time of foundation： UpToDate founded in 1992 is the earliest-established evidence-based medicine database; b） Management ideas： All 4 databases aim to integrate all the high quality evidences about some clini- cal topics and help doctors to make the most reasonable decisions at present; c） Editing process： The inclusive criteria of Clinical Evidence is more strict than other databases, for the evidence needs to go through 18 steps before it is included; and d） Update rate： DynaMed updates every day as the fastest than other databases. Conclusion A mature evidence- based medicine database needs a powerful methodology team, strong financial support and a large number of literature services. Besides learning good foreign experiences, it is also very important to assemble a methodology team, and par ticularly to integrate domestic characteristics for the establishment of domestic evidence-based medicine database.
