This study aims to improve both communication skills and behaviour by giving precise recommendations to physicians (3 step strategy) in their direct contact with patients' relatives. A 3-step physician-driven support strategy is used, that consists in 3 meetings with the relative - one before, one during and one after the patient's death. The underlying hypothesis is that this strategy will improve communication in the end-of-life setting and thus should reduce post-ICU burden for family members, specifically the development of prolonged grief 6 months after the death.
