This study of 37 CUMP caregivers who intervened during the Paris and/or Nice attacks found no PTSD. In addition, a satisfactory quality of professional life was found, with a low degree of emotional exhaustion associated with a moderate degree of dehumanization in the relationship with others, as was the degree of personal accomplishment. A tendency to distinguish 2 groups appears on certain results according to the number of days of cumulative intervention (lower or higher than 5).
