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

Death is a daily reality in the emergency department. Deaths represent 0.3 to 0.5% of emergency admissions, i.e. approximately 26,000 per year for the whole of France. For 80% of these deceased patients, a decision of withholding and withdrawing life-sustaining treatments was made in the emergency departments. The announcement of death and decision of withholding and withdrawing life-sustaining treatments in this context is complex because of the lack of time and the inappropriate places for the announcement. In addition, the short delay in the occurrence of these events may increase the stress and anxiety of families who are unprepared for the announcement. However, there is little data in the literature on the impact on families in terms of their experience of announcements in the emergency context. It has been established that symptoms of anxiety and depression are correlated with the onset of posttraumatic stress disorder and that the latter is more important in the families of deceased patients and after a decision to undergo decision of withholding and withdrawing life-sustaining treatments in the intensive care unit. In order to identify it, several tools have been developed, including the Impact Event Scale (IES), which has been widely used to detect symptoms related to PTSD. It has also been shown that training nursing staff in communication skills or the use of written support in dealing with the families of patients who have died in intensive care reduces the appearance of post-traumatic stress symptoms. Human simulation is a pedagogical technique for learning interpersonal skills through role playing. It is used, among other things, in announcement situations in medicine. Nevertheless, its impact in emergency medicine has not been evaluated. Moreover, it has been shown that the involvement of the patient-partner in the care process must be improved and encouraged and that its impact has yet to be evaluated. Therefore, the objective is to evaluate the impact of a model protocol for announcing decision of withholding and withdrawing life-sustaining treatments, with human simulation and the intervention of partner families in a simulation center and in situ, on the reduction of family stress following the announcement of a decision of withholding and withdrawing life-sustaining treatments in the emergency departments. Hypothesis is that training all emergency department caregivers in the use of a model announcement protocol with the support of human simulation, combining training of pairs in a simulation center and in situ training, and the participation of partner families, would allow for a better understanding of announce of withholding and withdrawing life-sustaining treatments decision in the emergency department and reduce their impact on families in terms of the occurrence of acute stress and post-traumatic stress symptoms.
