Abstract 220: Simulator Fidelity During Training Has No Impact on Achieving Goal Times in Mock Cardiac Arrests
Objectives: The American Heart Association (AHA) National Registry of CPR identifies interventions that if delayed will generate “process of care exceptions” which include starting CPR more than 1 minute after arrest, providing the first defibrillation more than 3 minutes after onset of Ventricular Fib (VF), and administering the first vasopressor more than 5 minutes after of arrest. Additional critical time intervals identified in the AHA 2005 Emergency Cardiovascular Care Guidelines include defibrillating VF at 2 minute intervals and resuming CPR immediately after defibrillation. This study examined the influence of simulator fidelity during training on achieving these goal times in a mock cardiac arrest.
Methods: 34 senior nursing students from four nursing programs participated in two AHA Advanced Cardiovascular Life Support (ACLS) courses. One was conducted using a high-fidelity simulator (n=16) and another with a low-fidelity simulator (n=18). After course completion, participants experienced an additional series of arrest cases conducted with a high-fidelity simulator during which data were obtained. The simulator event logs were reviewed for times to interventions with all times confirmed by video review.
Results: There were no significant differences in any of the times (Table 1). Both groups met target times for starting CPR, applying the first defibrillation, and administering the first vasopressor.
Conclusions: The introduction of high-fidelity simulators into an ACLS course did not significantly improve the times to start CPR after arrest, provide the first defibrillation after onset of VF, or administer the first vasopressor. Nor did it improve the time to restart CPR after defibrillation or the defibrillation interval time, although both groups had means well below the standard of 120 seconds.
