Abstract

In veterinary education, simulators are models or devices that can imitate a real patient or scenario and allow students to practice skills without the need for live patients. Castration is a common surgical procedure in all species, and the standing, open technique is frequently performed in horses. Although a simulator has been developed for equine closed castration, a simulator for standing castration in the horse has not yet been described. This two-part study focused on the design, creation, and evaluation of a simulator for teaching standing castration in the horse. A low-technology simulator was created using molded silicone testicles, cohesive bandage, stockings, and socks. A rubric was created for assessing performance using the simulator. Participants were recruited from three groups: university academic staff members (n = 12, majority equine veterinarians), equine veterinarians working in private practice (n = 9), and final-year veterinary students (n = 28). Each group tested the simulator while being graded using the developed rubric, and participants completed an anonymous online feedback questionnaire. Feedback was positive overall, with 98% of respondents (n = 48/49) stating that the model would be a useful addition to the veterinary curriculum. Furthermore, 100% of students reported that using the simulator increased their confidence in performing standing castration in horses. Evaluation of the model included assessment of responses from veterinarians and students regarding realism and usefulness of the simulator, comparison of rubric scores between veterinarians and students, and assessment of the reliability of the rubric. Median student rubric score was significantly lower than qualified veterinarians (p < .001), and Cronbach's alpha demonstrated that there was adequate internal reliability in rubric scoring (α = .85). It was determined that the simulator is effective for teaching the steps of the surgical procedure and for increasing student confidence.

开发和评估马匹站立阉割手术模拟器和评估标准。
在兽医教育中,模拟器是一种可以模仿真实病人或场景的模型或装置,让学生在不需要活体病人的情况下练习技能。阉割是所有物种的常见外科手术,马匹常采用站立式开放技术。虽然已经开发出了用于马匹闭合阉割术的模拟器,但用于马匹站立阉割术的模拟器尚未见报道。本研究由两部分组成,重点是设计、创建和评估用于马匹站立阉割教学的模拟器。使用模制硅胶睾丸、粘合绷带、丝袜和袜子制作了一个低技术模拟器。制作了一个评分标准,用于评估使用模拟器的表现。参与者分为三组:大学学术人员(12 人,大部分为马兽医)、在私人诊所工作的马兽医(9 人)和兽医专业毕业班学生(28 人)。每个小组都对模拟器进行了测试,同时使用开发的评分标准进行评分,参与者填写匿名在线反馈问卷。总体反馈是积极的,98% 的受访者(n = 48/49)表示该模型将成为兽医课程的有益补充。此外,100% 的学生表示,使用模拟器增强了他们对马匹站立阉割的信心。对模型的评估包括评估兽医和学生对模拟器真实性和实用性的反应、兽医和学生的评分比较以及评分标准可靠性的评估。学生评分的中位数明显低于合格的兽医(p < .001),Cronbach's alpha 表明评分标准有足够的内部可靠性(α = .85)。实验结果表明,模拟器能有效地教授手术步骤并增强学生的信心。

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.
