临床医务人员对循证医学认知与实践的现况调查

目的了解临床医务人员对循证医学认知与实践现况以及面临的主要困难，为临床更好开展循证医学实践提供参考。方法采用自编问卷对285名临床医务人员进行调查．并对组间差异进行比较。结果①调查对象的循证医学平均认知得分为6．19±2．62分，35．8％的人得分在8分以上。组间比较发现，来自三级医院、硕士及以上学历、工作年限〉10年者认知相对较好；②工作年限〉10年、硕士及以上学历的医生文献检索和信息获取能力相对较强；③医务人员循证医学的认知程度与其实践频率问存在关联（rs=0．21，P=0．000），认知程度越高，开展循证医学实践的频率越高。④影响循证医学实践的前三位因素是：时间不足、外语水平低以及循证医学资源了解不足。结论本次调查对象对循证医学的认知情况水平一般，需重点加强对硕士以下学历、工作年限〈10年、三级以下医院人员的循证医学培训，注意帮助其克服应用中的困难，促进循证医学的实践。

A Survey of Clinicians' Cognition and Practice of Evidence-Based Medicine

Objective To survey the status of the cognition and practice of evidence-based medicine （EBM） in clinicians, and the obstacles in their evidence-based practice. Methods 285 clinicians were surveyed by a self-made questionnaire. SPSS13.0 software was used for statistical analysis. Results The EBM average cognitive score of clinicians was 6.19±2.62, with 35.8% of effective samples scored 8 or more. Clinicians from the third-grade hospitals, with a degree of master or above and work experiences over 10 years knew EBM relatively better. Clinicians with a master degree or above, work experiences over 10 years had relatively good ability in EBM practices. The survey showed a connection between clinicians cognitive degree and their practice frequency in EBM（rs=0.21 ,P=0.000）. The result indicated that the higher the respondents acknowledge EBM, the more frequently they practiced it. The top three barriers which affected the use of EBM in clinical practices were： lack of time, poor proficiency in foreign language and shortage of EBM knowledge. Conclusion The current cognitions of clinicians on EBM are not very well. It is necessary to strengthen the training of clinicians, particularly, who have a degree under master, work experience less than 10 years and work for hospitals below third-grade level. To solve the difficulties in practicing EBM, promotion in their cognitions and active use of EBM is needed.
