Hospitals with more-active participation in conducting standardized in-situ mock codes have improved survival after in-hospital cardiopulmonary arrest.

Aim: The American Heart Association (AHA) and the Institute of Medicine have published a national "call-to-action" to improve survival from in-hospital cardiopulmonary arrest (IHCA). Our aim was to determine if more-active hospital participation in standardized in-situ mock code (ISMC) training is associated with increased IHCA survival.

Methods: We performed an ecological study across a multi-state healthcare system comprising 26 hospitals.
