摘要
目的 调查临床流行病学与循证医学在我国口腔医学领域中的应用情况。方法 2001年4月向口腔医学专业杂志主编、口腔医疗教学单位的主要负责人、知名专家及学术带头人发出了访问信,要求对所提出的有关问题进行答复或讨论,并对回信内容进行了综合分析。结果 至2001年6月底共收到12个大学和1个省会口腔医院专家的40到回信,占发信总量的20％。 主要论点是:循证口腔医学在中国还处在扫盲阶段,12个大学中有50％为研究生(其中2个包括本科生)开设了临床流行病学课程,25％为口腔医生/学生开设了循证医学讲座。只有1个大学为临床医师多次举办了循证医学学习班。在口腔临床存在着凭经验决策,注重经济效益忽视证据的不良倾向,在科研实践中存在着急功近利、不重视临床随机对照试验研究的问题。开设临床流行病学和循证医学课程,推广循证医学,产生或应用最佳证据非常重要。结论 在我国口腔医学领域循证医学刚刚起步。在口腔医务人员中推厂循证医学,以便产生和扩散更多的最佳口腔医学证据,是提高中国口腔医学水平的关键。
Objective To investigate problems in applying clinical epidemiology and evidence-based medicine in the field of dentistry in China. Method In early April of 2001, about 200 copies of a questionnaire were sent to chief editors of dental journals, directors and famous experts of the university dental schools and/or dental departments of the provincial/metropolitan hospitals located in the mainland of China. The sent back questionnaires were summarized and analysized. Results At the end of June, 2001, 40 replies from the experts of 12 universities and one metropolitan dental hospital were received. The main points are summarized as following: EBM in China is at starting stage of 'anti-illiteracy' campaign. There are 6 out of 12 universities having delivered clinical epidemiology courses to postgraduates (2 to undergraduates) , only 3 added lectures on evidence-based medicine to dental students and/or professionals, only one university held intensive training courses on EBM lo clinicians. In dental practice there are still some dentists making decisions simply by experiences. In the research practice some dentists are eager for quick success and instant benefits, ignoring scientific design and quality control of the studies. Randomized controlled clinical trials are seldom appeared in Chinese dental journals. To popularize EBM in all dental clinicians is important for them to use and produce the best evidences. Conclusions EBM in dental field of China is at starting stage. Collection and dissemination of best dental evidences in dental professionals is a key lo raise the dental care levels in China.
