Accompanying a dying person up to and at the actual moment of death is a duty that often leaves carers at a loss. We shall show to what extent theoretical nursing knowledge can help practitioners who accompany people at the end of their life by applying two theories of care: Reed’s theory of self-transcendence and Meleis’s theory of transition. Our interpretation of the theory of self-transcendence designates three points of reference in the concept of dying well. The first relates to the overtures prompted by the vulnerability that the context of dying inspires. The second concerns the capacity of the patient to summon up intrapersonal, interpersonal, and transpersonal strategies, whilst the third considers the benefits when self-transcendence is achieved. The theory of transition similarly presents three points of reference. The first is based on informing the patient about palliative care and telling him or her the truth about the prognosis. The second relates to coordinating the interprofessional team that is looking after the dying person. The last criterion is that palliative care should be started at a suitable moment. This makes it possible to educate a patient who wishes to die at home and thus create an environment favorable to the transition.
