Abstract:
Simulation-based training is useful in improving physicians' skills. However, no randomized controlled trials have been able to demonstrate the effects of simulation teaching in real-life patient care. This study aimed to determine whether simulation-based training or an interactive seminar resulted in better patient care during weaning from cardiopulmonary bypass (CPB)-a high stakes clinical setting. Methods This study was conducted as a prospective, single-blinded, randomized controlled trial. After institutional research board approval, 20 anesthesiology trainees, postgraduate year 4 or higher, inexperienced in CPB weaning, and 60 patients scheduled for elective coronary artery bypass grafting were recruited. Each trainee received a teaching syllabus for CPB weaning 1 week before attempting to wean a patient from CPB (pretest). One week later, each trainee received a 2-h training session with either high-fidelity simulation-based training or a 2-h interactive seminar. Each trainee then weaned patients from CPB within 2 weeks (posttest) and 5 weeks (retention test) from the intervention. Clinical performance was measured using the validated Anesthesiologists' Nontechnical Skills Global Rating Scale and a checklist of expected clinical actions. Results Pretest Global Rating Scale and checklist performances were similar. The simulation group scored significantly higher than the seminar group at both posttest (Global Rating Scale [mean +/- standard error]: 14.3 +/- 0.41 vs. 11.8 +/- 0.41, P & lt; 0.001; checklist: 89.9 +/- 3.0% vs. 75.4 +/- 3.0%, P = 0.003) and retention test (Global Rating Scale: 14.1 +/- 0.41 vs. 11.7 +/- 0.41, P & lt; 0.001; checklist: 93.2 +/- 2.4% vs. 77.0 +/- 2.4%, P & lt; 0.001). Conclusion Skills required to wean a patient from CPB can be acquired through simulation-based training. Compared with traditional interactive seminars, simulation-based training leads to improved performance in patient care by senior trainees in anesthesiology.
