The Effect of Simulation Training in Anesthesia on Student Operational Performance and Patient Safety

A veterinary anesthesia simulated environment (VASE) with clinical scenarios has been integrated into the pre-clinical curriculum at Midwestern University College of Veterinary Medicine to simulate anesthesia of a live patient within a surgical suite. Although this modality was shown to significantly improve veterinary students' perceived preparedness to perform anesthesia on live patients, whether this would improve anesthesia competency in the actual clinical environment, described as operational performance, remained unclear. Our goal was to examine the relationship between anesthesia simulation training and student anesthesia operational performance. Anesthesia operational performance assessment of students was determined by quantifying critical event occurrences that negatively impacted patient safety during the anesthesia of 287 patients during students' initial surgical experience in 2015 and 2016. The relationship between total numbers of critical incidents to students having anesthesia simulation training was determined through evaluation of anesthesia records from 2015 and 2016, where students did not have anesthesia simulation training or they had pre-clinical training, respectively. Results showed a significant relationship between simulation training and critical incident occurrence, with a critical incident more likely to occur during patient anesthesia for students who did not experience pre-clinical anesthesia simulation training. Of the total critical incidents that occurred in the two-year study, 88% were in patients anesthetized by students who did not have simulation training. Our findings suggest that students who were given the opportunity to participate in anesthesia-focused simulations before a live-animal anesthesia encounter demonstrated significant improvements in anesthesia operational performance and improved patient safety.
