Abstract
Purpose
The objective of this study was to determine the impact of a low-fidelity simulation model on mastering the sterile technique during placement of epidural catheters.
Methods
Trainees, including residents and fellows, were given conventional teaching consisting of a lecture and a video demonstration on the appropriate sterile technique to apply during the placement of epidural catheters. The trainees were then provided with a one-on-one demonstration session using a low-fidelity Styrofoam™ epidural model, followed by a series of simulation sessions. After conventional teaching and following each simulation session, the trainees were assessed on their performance until competence was achieved based on a 15-point checklist. The retention of competence was subsequently evaluated bi-weekly in clinical practice for four assessments.
Results
Twenty-one trainees participated in the study. The average score for the residents following conventional teaching was 6.0 out of 15 points on the checklist. Following the initial one-on-one hands-on demonstration, the average score increased to 10.8 (difference = 4.8, 95% confidence interval (CI): 3.3 to 6.2; P < 0.001). The average score for the fellows following conventional teaching was 7.9 out of 15 points on the checklist. Following the initial one-on-one hands-on demonstration the average score increased to 11.2 (difference = 3.3, 95% CI: 0.05 to 6.6; P = 0.047). During the retention of competence phase, scores ranged from 13-15 for both residents and fellows.
Conclusion
This study describes a comprehensive teaching model for mastering the sterile technique during epidural catheter placement. It suggests that low-fidelity simulation improves the learning process when used in addition to conventional teaching.
