[Patient partner approach into question].

Patient engagement in health care system can be regarded as a lever for the general improvement of people's health, the quality and safety of care. Among the many approaches that co-exist, the model of Patient Partner is relatively recent and declares itself as the most successful to promote this engagement. The authors of this article propose to present briefly the above model and to raise the remaining questions on its operational application. We will then present the research program «Patient Partner Approach to Care» (INTERREG Va) that questions the Patient Partner model in an interregional context (Wallonia - Grand Duchy of Luxembourg - Lorraine - Rhineland-Palatinate and Saarland).
