During the first surge of the COVID-19 pandemic, a rapid redeployment of noncritical care healthcare staff was necessary to meet the unprecedented number of patients needing critical care. A New York health system developed a multidisciplinary simulation training program to prepare the redeployed staff for new roles in the intensive care unit (ICU). The training included courses on management of a patient with acute decompensation with COVID-19, critical care basics for the non-ICU provider, and manual proning of a mechanically ventilated patient.
