Only 17% of in-hospital cardiac arrest patients survive. Simulation-based crisis resource management (CRM) teamwork training may help. However, cost constrained hospitals are reluctant to commit the necessary resources to sustain recurrent CRM training of hundreds of housestaff annually. RRT ICU nurses are permanent staff who can be trained once. I propose a QI study to determine the impact on team practice performance, patient outcomes, and measures of institutional efficiency when simulation-based CRM trained first responder ICU nurses leverage this CRM knowledge by teaching housestaff in a real-time in-situ interprofessional education-facilitator paradigm associated with imminent and actual cardiopulmonary and respiratory arrests.
