This study evaluated whether one supervised simulated ovariohysterectomy (OVH) using a locally developed canine OVH model, decreased surgical time for final-year veterinary students' first live-animal OVH. We also investigated student perceptions of the model as a teaching aid. Final-year veterinary students were exposed to an OVH model (Group M, n = 48) and compared to students without the exposure (Group C, n = 58). Both groups were instructed similarly on performing an OVH using a lecture, student notes, a video, and a demonstration OVH performed by a veterinary surgeon. Students in Group M then performed an OVH on the model before performing a live-animal OVH. Students in Group C had no exposure to the OVH model before performing a live-animal OVH. Surgical time data were analyzed using linear regression. Students in Group M completed a questionnaire on the OVH model after performing their first live-animal OVH. The OVH model exposure reduced students' first canine live-animal OVH surgery time (p = .009) for students without prior OVH experience. All students (n = 48) enjoyed performing the procedure on the mode; students practicing an OVH on the model felt more confident (92%) and less stressed (73%) when performing their first live-animal OVH. Results suggest that the canine OVH model may be helpful as a clinical training tool and we concluded that the OVH model was effective at decreasing students' first OVH surgical time.
