Background: The background of this study is the recent adoption and updates of surrogate medical decision making in France. The legal designation of a trusted person, meant to ensure that the patient's wishes are made known, has first been introduced in France by the 2002 law on the rights of the sick and the quality of the health system (also known as “Kouchner law”). Some updates came later with the 2005 law relative to patient’s rights and end of life (« Leonetti law ») and the 2016 law on the rights of persons at the end of life (« Claeys-Leonetti law »). The study addresses the question of the effectiveness and challenges of this system in the French context.Objective: The review was guided by the question: “what is the extent of research in France on patient-centered, family-centered and health professionals-centered outcomes associated with the trusted person system, when elderly patients are involved?”. The aims are to measure the extent of the research on surrogate medical decision-making research in France for elderly patients, how well all subpopulations are represented, the methodologies used and whether they are sufficient in describing patient-centered, family-centered and health professionals-centered outcomes associated with surrogate medical decision-making.Searches: We used 11 scientific databases in order to conduct our research: PubMed, ScienceDirect, EconLit, CINHAL Plus, Embase, LISSA, Cairn.info, the Bibliothèque numérique de droit de la santé et d'éthique médicale (BNDS), the Banque de données en santé publique (BDSP), the Catalogue et index des sites médicaux de langue française (CISMEF) and the Plateforme nationale pour la recherche sur la fin de vie (PNRFV).Types of study to be included: Quantitative, qualitative, and mixed-method studies were included in order to consider different aspects of research and data collection on surrogate medical decision making.Design: Online databases were used to identify papers published during the period 2002-2021, from which we have selected publications written in French or English, applying our search strategies.
