Background Collaborative practice in primary health care increases care quality and security. In France, primary health care professionals increasingly work together. The link between general practitioners (GPs) and community pharmacists (CPs) is an important element. Nevertheless, effective collaboration between GPs and CPs is difficult to develop and formalize. Interprofessional education has been identified as a necessary step to prepare “collaborative practice-ready professionals”. We aimed to identify the interprofessional training needs of last-year GP and CP students to develop interprofessional collaborations. Method We conducted an analysis of training needs using a method inspired by occupational didactics. We collected data through individual semidirective interviews with CPs and GPs in 2022. At each stage we aimed to identify the elements of the occupational didactics to deduce the training needs in the form of a frame of reference: apparent competencies, emblematic situations and acting characteristics. We conducted an initial deductive thematic analysis to identify the apparent competencies of the two professions, the emblematic situations in which these competencies are used, and the acting characteristics used in these situations. We made an inductive categorization to define the collaborative competence and the families of situations and to model the actions of this GP-CP collaboration. Results We defined the competency “to collaborate effectively in an interprofessional setting in order to respond to care issues in one’s territory” expressed in various professional situations. We described it by three capacities based on two interacting dynamics: one-off exchanges and structured collaborations. Various communication tools facilitate the implementation of these interactions. We modeled the actions of the GP-CP collaboration in the form of a conceptual map. Conclusion The collaboration between the CP and the GP implements a competency that could be integrated into their professional referential. This competency, entitled “collaborating effectively in interprofessional settings to respond to care issues in one’s territory”, is expressed in a variety of professional situations. It is based on two parallel and interacting dynamics: one-off exchanges and a dynamic of lasting collaboration. This study thus lays the groundwork for the development of this collaborative skill among general practice and pharmacy residents.
