[Definition and evaluation of a multidisciplinary patient's pharmacotherapy management method: The pharmaceutical care plan]. / Définition et évaluation d'une méthodologie interprofessionnelle d'optimisation de la pharmacothérapie des patients : le Plan de Médication Partagé.

The implementation of pharmaceutical monitoring as defined by the Council of Europe in its Resolution of March 2020 requires defining for each patient, objectives and a treatment plan, to share, monitor and update them in a manner coordinated, interprofessional and in partnership with the patient. It recognizes the central place of the pharmacist by encompassing all of its clinical pharmacy activities and emphasizes the need for interprofessional collaboration (Hepler CD, Strand LM. Opportunities and Responsibilities in Pharmaceutical Care. American Journal of Hospital Pharmacy. Mars 1990; 47(3): 533-543). This work first presents the pharmaceutical care plan as a multiprofessional methodology that meets the objectives of pharmaceutical monitoring, then in a second step its evaluation through two regional projects. The pharmaceutical care plan unites, around the patient, all the actors involved in their pharmacotherapy, throughout their care path. It makes it possible to control the iatrogenic drug risk and includes the patient's drug management with regard to curative, preventive and palliative objectives and in a global strategy for the care and promotion of patient health. This methodology is integrated into coordinated exercise strategies and care pathway approaches. Several levers will help support its deployment, such as inter-professional education and digital health tools.
