Abstract
Because timely and efficient responses of nurses are paramount to patient survival in cardiac and respiratory codes, it is crucial to determine best methods of training nursing personnel to respond effectively to code situations. Human factors engineering (HFE) is a relatively new approach in health care that attempts to understand human vulnerabilities that contribute to error and then design systems that minimize the likelihood of error occurring. This study embedded the principles of HFE in the design, implementation, and evaluation of mock code training to determine whether mock codes using HFE were helpful and if so, which inpatient units would benefit the most from such drills.
