Impact of high-fidelity simulation on the performance of oxygenator change-outs among perfusion students.

BackgroundSimulation is increasingly utilized in the clinical training of healthcare professionals. Many perfusion programs in the United States use simulation to teach students both technical skills and effective communication. However, there is a lack of clarity regarding the optimal timing for introducing simulation into the curriculum and how to assess students' competencies. This study aims to evaluate whether combining simulation with didactic education is more effective than didactic education alone for learning perfusion-specific tasks, such as oxygenator changeouts.MethodsThis was a pilot, randomized controlled study conducted during November 2020. Subjects who were in their first year and enrolled in a cardiovascular perfusion program at the university were included. Subjects were randomly assigned to receive didactic education alone (control) or didactic in combination with the simulation training (experimental). Both groups received the didactic portion of the oxygenator change out procedure and the experimental group received supplemental simulation training. The primary outcome was oxygenator change-out completion time (recorded in minutes and seconds) to identify and change-out an oxygenator in a cardiopulmonary bypass circuit. The secondary outcome was total communication score and subject's overall performance assessment using the scoring system referenced by Burkhart et al.ResultsThe experimental group (n = 8) performed the oxygenator change-out significantly faster (363.63 ± 87.1 seconds vs 558.11 ± 185.75 seconds, p = .016) as compared to the control group (n = 9). However, there was no significant difference between the control and experimental groups in overall communication skills (p = .152) or the scoring system (p = .053) used to score subjects technical skills.ConclusionThe study findings revealed that the group receiving both didactic instruction and simulation performed an oxygenator change-out significantly faster than the group that received only didactic instruction. These results suggest that incorporating simulation of emergency scenarios into perfusion training can enhance students' speed in performing complex tasks, better preparing them for real clinical situations.
