Abstract

Vaginal cytology is a widely used cytological technique mostly taught by observation, either through direct tutoring or videos. To the best of our knowledge, vaginal cytology simulators have never been assessed in veterinary medicine. Twenty-five undergraduate students with no prior experience in canine vaginal sampling were randomly assigned to two groups that either practiced the procedure in a simulator or a live animal. An inverted classroom design was followed. After observing a video tutorial, students practiced with the simulator/live animal for two classes. Three weeks later, they performed a vaginal cytology on a live animal being recorded. The videos were evaluated through an objective structured clinical examination (OSCE) by an observer blinded to the student's groups. The learning outcome was compared through OSCE pass rates and questionnaires. The simulation model was made by 3D printing and soft silicone for the vulvar labia, having pink and blue colored vaseline in the correct and incorrect locations for sampling. The model was economic and accurately replicated the female reproductive tract. It provided immediate feedback to students, by obtaining pink or blue swabs from the correct and incorrect locations, respectively. Students reported that three to five or more attempts were needed to properly learn the procedure, thus justifying the need for a simulator. No differences in the OSCE pass rates were observed between the groups. The simulation model was effective for learning the vaginal cytology procedure, replacing the use of live animals. This low-cost model should be incorporated in the tool-kit of reproduction classes.
