Development and validation of a feline medial saphenous venipuncture model and rubric

Abstract

Cats are extremely popular pets with the reputation of being uncooperative for even common procedures, such as venipuncture. In this study, we sought to create and validate a cat medial saphenous venipuncture model and rubric for use in veterinary training. The validation framework consisted of content evidence, internal structure evidence, and relationship with other variables. Eleven veterinarians and veterinary technicians who were experienced with the procedure evaluated the model by means of a survey. These experienced participants, along with 25 veterinary students who were novices at the skill, performed venipuncture on the model while being digitally recorded. One hundred percent of the experienced participants and 88% of the novices reported that the model was helpful for teaching feline medial saphenous venipuncture. They identified a few areas for continued improvement, including increasing the blood flow rate and decreasing the vessel wall rigidity. Experienced users' rubric scores were significantly higher than novice students' (experienced, M = 13.4; novice M = 16.5; p = .05), suggesting that the model's features were adequate to differentiate the performances of various users. Internal consistency of the eight-item rubric was acceptable at .74. These results supported validation of the cat medial saphenous model and rubric for use in veterinary education.
