EVIDENCE-BASED PRACTICE PROJECT REPORT Submitted to the School of Nursing and Health Professions of Colorado Christian University Lakewood,Colorado in partial fulfillment of the requirements For the degree of DOCTOR OF NURSING PRACTICE Abstract: New Graduate Nurses (NGN's) are entering the workforce with a practice gap between what is learned in nursing school andwhat happens in clinical practice after graduation (Hommes, 2014). High-fidelity simulation (I-IFS) is often used in nursing schools, as well asthe hospital education setting, as it provides a safe environment forparticipants to practice clinical skills. The purpose of this Doctor of Nursing Practice (DNP) Evidence-Based Practice (EBP) project was to evaluate the impact of a high-fidelity mock code simulation intervention on NGN's self-confidence and anxiety while responding to a deteriorating patient. The I-IFS interventionwas conducted with 10 new graduate nurse participants at the project facility using the Nursing Anxiety and Self-Confidence with Clinical Decision Making Scale (NASC-CDM) © created by Dr. Krista A. White. The pre- and postself-confidence for Dimension 2 was statistically significant (alpha = 0.05, (9) = -2.43, p =-038) and the pre- and post-anxiety for Dimension 3 was statistically significant (alpha = 0.05, (9) = 3.11, p = .013). While the participants felt additional clinical experience and HFS was needed to improve self confidence andanxiety when responding to a deteriorating patient, HFS intervention can beused to improve clinical performance. The implications for practice indicate more hands-on practice is needed to increase self-confidence and decrease anxiety. The implications for education include more high-fidelity simulation for new graduate nurses and additional clinical practice to increaseself confidence and decrease anxiety. Implications for research indicate more research is needed using high-fidelity simulation related to training new graduate nurses to decrease anxiety and increase self-confidence.
