Impact of a Protocol for Announcing Decision of Withholding and Withdrawing Life-sustaining Treatments on the Stress of the Relatives in the Emergency Departments

"The emergency services will be divided into 4 clusters (2 or 3 services per cluster). Each cluster will belong successively to the control arm and then to the intervention arm according to a 5 successive steps of 4 months duration (stepped wedge method). The deployment of the training will therefore not be done simultaneously in the different services.~Individuals in this group will have received a decision of withholding and withdrawing life-sustaining treatments according to the DISCUSS announcement protocol, by a professional trained in this procedure."
