Objective
To predict readiness for laparoscopic ovariectomy of live dogs on the basis of performance on a high‐fidelity laparoscopic abdominal simulator and to determine interrater reliability of the assessment.
Study design
Experimental study.
Sample population
Seventeen fourth‐year veterinary students.
Methods
After a standardized laparoscopic training course, each participant performed a laparoscopic ovariectomy with a simulator. This performance was scored in real time by two evaluators using a rubric. Participants achieving a score of 112 of 160 performed a laparoscopic ovariectomy in a live dog, supervised by an instructor in the room. Two evaluators scored video recordings of each procedure using the rubric. Participants' opinions about the simulator were collected with a survey.
Results
All participants scored above the threshold (range, 126‐151) and successfully completed laparoscopic ovariectomy in a live dog, with an average of 10 of 17 participants requiring verbal guidance and 5 of 17 participants requiring intervention from the instructor. Interrater concordance was excellent for the rubrics used to score performance on the simulator (R = 0.91) and in vivo (R = 0.81). All participants agreed that the simulator should be used to assess trainee readiness prior to surgery in a live dog.
Conclusion
Participants achieving a score of at least 126 of 160 on the simulator were able to perform a laparoscopic ovariectomy in a live dog under supervision. The scoring system for the simulator had excellent interrater concordance.
Clinical significance
This simulator and scoring system can be used in laparoscopic training programs to assess readiness for progression to the operative setting.
