摘要

诊断样本的收集,包括静脉穿刺,是诊断和治疗牛的关键。临床技能模型允许学习者在对活体动物执行技能之前练习技能并提高他们的能力;然而,存在的牛模型相对较少。本研究旨在利用内容证据、内部结构证据和与其他变量的关系证据组成的验证框架,开发和验证用于兽医学生教学和评估的牛尾骨静脉穿刺模型和规则。兽医学生(n = 38)和经验丰富的兽医(n = 12)对模型进行静脉穿刺并进行录像。录音用一个六项标准和一个全球评级分数进行盲目评分。记录完成任务的时间和针的总数。兽医报告说,该模型适合学生学习执行任务(内容证据)。Rubric评分具有可接受的信度(a = .783,内部结构证据)。兽医获得更高的评分,使用更少的针头来完成任务(p = 0.033和0.047,与其他变量的关系-训练的证据水平)。学生的调查反应非常积极。本研究收集的证据支持模型和标题的验证。使用经过验证的模型和规则使教育者能够可靠地教授和评估技能,并且该模型允许学生重复练习技能,减少了对活体动物的使用。需要进一步的研究来评估该模型,以便在兽医技术人员、推广人员和畜牧生产者的教学中使用。

Development and Validation of a Bovine Coccygeal Venipuncture Model and Rubric.

Diagnostic sample collection, including venipuncture, is critical to diagnosing and treating cattle. Clinical skills models permit learners to practice a skill and improve their competency before performing the skill on a live animal; however, relatively few bovine models exist. This study aimed to develop and validate a bovine coccygeal venipuncture model and rubric for teaching and assessing veterinary students using a validation framework consisting of content evidence, internal structure evidence, and relationship with other variables evidence. Veterinary students (n = 38) and experienced veterinarians (n = 12) performed venipuncture on the model while being video recorded. Recordings were scored blindly using a six-item rubric and a global rating score. Time to perform the task and total number of needle sticks were recorded. Veterinarians reported that the model was suitably realistic for students to learn to perform the task (content evidence). Rubric scores had acceptable reliability (a = .783, internal structure evidence). Veterinarians received higher rubric scores and used fewer needle sticks to complete the task (p = .033 and .047, relationship with other variables evidence-level of training). Students' survey responses were very positive. The evidence collected in this study supported validation of the model and rubric. The use of validated models and rubrics allows educators to teach and assess skills reliably, and the model allowed students to practice the skill repetitively, reducing the use of live animals. Additional studies would be necessary to evaluate the model for use in teaching veterinary technicians, extension agents, and livestock producers to perform this task.

期刊介绍: The Journal of Veterinary Medical Education (JVME) is the peer-reviewed scholarly journal of the Association of American Veterinary Medical Colleges (AAVMC). As an internationally distributed journal, JVME provides a forum for the exchange of ideas, research, and discoveries about veterinary medical education. This exchange benefits veterinary faculty, students, and the veterinary profession as a whole by preparing veterinarians to better perform their professional activities and to meet the needs of society. The journal’s areas of focus include best practices and educational methods in veterinary education; recruitment, training, and mentoring of students at all levels of education, including undergraduate, graduate, veterinary technology, and continuing education; clinical instruction and assessment; institutional policy; and other challenges and issues faced by veterinary educators domestically and internationally. Veterinary faculty of all countries are encouraged to participate as contributors, reviewers, and institutional representatives.
