Mock code simulation training significantly improves registered nurses' performance in responding to medical emergencies. This training enhances confidence and reduces critical response times, such as cardiopulmonary resuscitation (CPR) and defibrillation.
Area of Science:
- Medical Education
- Emergency Medicine
- Nursing Simulation
Background:
- Registered nurses require effective training to manage medical emergencies.
- Traditional training methods may not fully prepare nurses for high-stress scenarios.
- Simulation-based training offers a controlled environment to practice critical skills.
Purpose of the Study:
- To evaluate the effectiveness of in-situ mock code simulation training.
- To improve registered nurses' responder performance in emergency situations.
- To assess the impact of simulation on nurses' confidence and response times.
Main Methods:
- Monthly in-situ mock codes conducted on medical-surgical/telemetry units.
- Utilized a 3-G Sim Man and unit-specific emergency equipment for realistic scenarios.
- Included debriefing, post-surveys, and evaluation of participant confidence and response times (CPR, defibrillation).
Main Results:
- Over 250 nurses participated in the 'Five Alive' course.
- Participants reported increased confidence in recognizing patient deterioration post-simulation.
- Demonstrated significant improvement in the time to initiate cardiopulmonary resuscitation (CPR) and defibrillation.
Conclusions:
- In-situ medical emergency team/code simulation with debriefing enhances responder performance.
- The 'Five Alive' program is an effective monthly training tool for nurses.
- Scheduling simulations to minimize disruption to patient care remains a logistical challenge.
