To identify and explore common barriers to the adoption of evidence-based medicine (EBM) practice in the undergraduate setting.
Nested longitudinal, focus group-based, qualitative study. Setting The University of Hong Kong Medical School, Hong Kong, China.
A group of 39 Year 4 medical undergraduates who participated in an EBM intervention cluster randomised crossover trial.
Students' attitudes, opinions and perceptions of barriers to EBM use.
General attitudes towards EBM and the teaching intervention were positive. Four sets of barriers to greater EBM use were identified as follows. (1) Learning environment including prevailing norms for student learning involving examination-oriented, textbook learning, prior availability of clinical practice guidelines, lack of encouragement from teachers and economy of time by utilising teacher expertise. (2) Limitations of evidence consisting of poor point-of-care access to medical literature, difficulty in locating evidence and the perceived low relevance of overseas evidence to Chinese patients. (3) Lack of opportunity to practise EBM due to lack of continuity of care and anxieties about negative teacher attitudes towards EBM use at the point-of-care. (4) Time constraints such as competing study demands and long evidence search time.
Significant barriers to the successful implementation of EBM learning in the clinical clerkship setting were identified. These can be specifically targeted to ameliorate any inhibition of clinical learning they may impose.
识别并探讨本科阶段采用循证医学(EBM)实践的常见障碍。
嵌套式纵向、基于焦点小组的定性研究。地点:中国香港大学医学院。
一组39名四年级医学本科生,他们参与了一项EBM干预整群随机交叉试验。
学生对EBM使用障碍的态度、意见和看法。
学生对EBM及教学干预的总体态度是积极的。确定了阻碍更多地使用EBM的四组障碍,如下所述。(1)学习环境,包括以考试为导向、基于教科书学习的学生学习普遍规范、临床实践指南的预先可得性、教师缺乏鼓励以及利用教师专业知识节省时间。(2)证据的局限性,包括即时医疗中获取医学文献困难、查找证据困难以及认为国外证据与中国患者相关性低。(3)由于缺乏连续护理以及担心教师在即时医疗中对EBM使用持负面态度,缺乏实践EBM的机会。(4)时间限制,如竞争性的学习需求和漫长的证据检索时间。
确定了临床实习环境中成功实施EBM学习的重大障碍。可以针对这些障碍采取具体措施,以减轻它们可能对临床学习造成的任何抑制。
