Abstract

Bovine practitioners expect new graduates entering clinical practice to be able to place a caudal epidural. Teaching this task on models facilitates scheduled training sessions and sufficient practice to reach competency. This study sought to create and validate a bovine caudal epidural model and scoring rubric using a framework of content evidence, internal structure evidence, and relationship with other variables evidence. Veterinarians (n = 11) and students (n = 40) were video recorded while placing a caudal epidural on the model. Recordings were scored by a blinded rater. Participants completed a survey evaluating the model's features, ease of use, and anticipated best use. Veterinarians reported that the model was helpful for students to learn and practice the task and that the model had sufficient landmark features and realism (content evidence). Rubric scores achieved acceptable internal consistency after one item was dropped (α = .736; internal structure evidence), and there was no significant difference between veterinarians' and students' performance scores on the model (relationship with other variables evidence). Survey feedback indicated the task on the model was simple, allowing students to achieve scores similar to those of veterinarians. Therefore, the model and rubric were not able to be validated using this study's validity framework. However, there are simple clinical skills models used in veterinary education and other health care fields, and research suggests that learning does take place on these models. Educators must consider whether simple models that are helpful for students to practice their skills may still have value, even if they are not able to be validated.

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.
