Using medical simulation technology, a novel, longitudinal, multidisciplinary critical care simulation curriculum for all interns caring for adult patients was developed and implemented within a tertiary care hospital system. This experiential curriculum resulted in increased learner confidence in select critical care topics, procedural skills, and communication skills prior to matriculation to the second postgraduate year. This curriculum resulted in a high level of learner satisfaction and desire for additional simulation-based training within their second postgraduate year. Due to the success of this local curricular innovation, the curriculum has expanded to learners from three other teaching hospitals within our system and has unified critical care education for all interns caring for adult patients at multiple hospitals within our system.
