Effect of a Stress Inoculation Training Intervention on Student Registered Nurse Anesthetist Performance in a Crisis Simulation
MetadataShow full item record
This study investigated the effect of a single Stress Inoculation Training intervention on Student Registered Nurse Anesthetists (SRNAs) in a high-fidelity crisis simulation. The primary objective was to improve technical and non-technical performance. The secondary objective was to decrease the subjective experience of stress. The Neuman Systems Model provided the theoretical framework for this study. This was a prospective randomized single-blinded study of senior SRNAs enrolled in a Crisis Resource Management course. Independent samples t-test, multiple correlation, and MANCOVA were used for statistical analysis. The intervention group showed a non-statistically significant trend toward higher mean performance, with less of an increase in heart rate. Increased age was significantly correlated with worse performance and higher likelihood of an acute stress response. SRNAs with more critical care experience had significantly less baseline stress resilience and were more likely to report perceiving the simulation as stressful. This project highlights the potential positive impact of training SRNAs for the stress of clinical practice. Future research is necessary following a similar protocol but with a larger sample size, incorporating multiple sessions, and including junior SRNAs. The ease of implementation combined with the myriad potential benefits warrants consideration for incorporation into an existing Nurse Anesthetist program.
