Pediatric, cardiopulmonary arrest is a rare event outside intensive care units in children's hospitals. Medical-surgical RNs rarely are involved in code situations and are often uncomfortable in performing necessary tasks. We implemented a multi-disciplinary educational plan, coupled with in-situ high-fidelity simulation, aimed at improving medical-surgical, RN comfort levels during codes. 260 medical surgical RNs on 10 separate hospital units parficipated. Pre and post intervention surveys were collected and compared. Results revealed a significant increase in the proportion of RNs responding "very comfortable" in all categories. Education, coupled with in-situ high-fidelity simulation, is an effective tool to increase RN comfortable levels during codes.
