In France, patients’ right to take part in decisions regarding their health has been recognized by law since 2002. This legal recognition was the outcome of a long-standing call to allow all individuals to be “actors in their own health” and to co-develop their care pathway with the professionals involved. In practice, care pathways simultaneously intertwine both standardization and personalization dynamics, which involve different forms of professional-patient interaction. This article analyses the links between the organizational variables of care pathways, and the ways in which patients are involved in the management of their own pathway. To date, these links have received little attention in the management science and health literatures. We draw on material from a case study carried out in 2 French territories, combining the analysis of patient pathways with interviews conducted with professionals and carers. Building on this analysis, we propose a typology of patient profiles which distinguishes between their different forms of involvement in the development of their care pathway, based on its organizational characteristics.
