Evidence-based veterinary medicine (EBVM) is of interest and relevance to veterinary practitioners. Consequently, veterinary schools take responsibility for teaching students how to appraise scientific articles and for equipping them with the skills needed to obtain and evaluate the best evidence and to apply this approach to their own cases. As part of our farm animal clinical rotation, we train students in qualitative and quantitative EBVM methods using an e-learning environment, online teaching materials, a wiki (a Web site that allows its users to edit its content via a Web browser), and face-to-face tutorials that support learning. Students working in small groups use a wiki to record details of the history, clinical presentation, diagnostic tests, herd data, and management plans for their chosen farm animal clinical cases. Using a standardized patient, intervention, comparison, and outcome (PICO) format, each group formulates a patient question based on either a proposed intervention or diagnostic procedure for the case and conducts an online scientific literature database search. The students appraise the articles retrieved using EBVM approaches and record the information in the wiki. The summation of this body of work, the group's critically appraised topic (CAT), includes the original PICO, a standardized table of the scientific evidence for the effectiveness of the intervention or diagnostic procedure, a summary statement in the form of a clinical bottom line, and their reflections upon the CAT. At the end of the rotation, students take part in a structured "CAT Club" where they present and discuss their findings with fellow students and clinicians.
循证兽医学（EBVM）对兽医从业者来说既有趣又有相关性。因此，兽医学院负责教授学生如何评估科学文章，并使他们具备获取和评估最佳证据以及将这种方法应用于自身病例所需的技能。作为我们农场动物临床轮转的一部分，我们使用电子学习环境、在线教学材料、维基（一个允许用户通过网络浏览器编辑其内容的网站）以及支持学习的面对面辅导，对学生进行定性和定量的循证兽医学方法培训。以小组形式开展工作的学生使用维基记录他们所选农场动物临床病例的病史、临床表现、诊断测试、畜群数据以及管理计划的详细信息。每个小组采用标准化的患者、干预措施、对照和结果（PICO）格式，根据针对该病例提出的干预措施或诊断程序提出一个患者问题，并进行在线科学文献数据库搜索。学生们使用循证兽医学方法评估检索到的文章，并将信息记录在维基中。这项工作的总结，即小组的严格评价主题（CAT），包括原始的PICO、干预措施或诊断程序有效性的科学证据的标准化表格、以临床要点形式呈现的总结陈述，以及他们对CAT的思考。在轮转结束时，学生们参加一个结构化的“CAT俱乐部”，在那里他们与同学和临床医生展示并讨论他们的发现。
