Respect des volontés en fin de vie : étude de faisabilité d'une information sur la personne de confiance et les directives anticipées

This prospective interventional study aims to show the feasibility and impact of information procedure on surrogate and advance directives (AD), for patients with incurable lung or gastrointestinal cancer. The intervention consisted of two semi-structured interviews. The first included: collection of preferences for prognostic information and involvement in decision-making, initial assessment of knowledge, information and surrogate and DA. The second assessed the impact of the first interview on knowledge, surrogate designation and DA writing, the assessment procedure by the patient and assessment of anxiety generated. Among 77 eligible patients, 23 (30 %) were included, 6/29 (21 %) refused to participate, 20/23 (87 %) completed both interviews. Patients not included had a higher 4-month death rate than included ones (39 % vs. 4 %, P = 0.002). Patients included had high expectations of information and appreciated it be delivered early, by someone not involved in their care. The study shows the feasibility of the procedure and its impact on the use of surrogate and DA by patients, however, revealing the complexity of approaching end-of-life wills and the importance of a process of anticipated discussion.
