[Innovative transformation of the health system through a preventive transition].

Given today's evolution of the healthcare system, organizational transformations, technological developments and major challenges, innovation has taken on primordial importance. In this context and with considerable support, many experimentations have taken place. Unfortunately, few have managed to scale up. What results is a congeries of innovations without a future, possibly avoidable squandering of resources, a number of missed opportunities, and the grim prospect of inventor burnout. As regards prevention, innovation is at the heart of an anticipated "preventive transition" of the health system that has yet to achieve operational status. In this article we attempt to redesign the contours of innovation in health, considering it first and foremost in regard to its social utility. We will go on to explore the limitations of innovative practices that delay the arrival of advances in health. Four types of obstacles appear: faulty evaluation; insufficient dialogue between researchers, stakeholders and decision-makers; lack of visibility and, finally, conceptions and perceptions of innovation characterized by tunnel vision. In the concluding section of this paper, we will present several tracks through which the innovation process could be impelled to drive health system transformation. They consist in: (i) incorporating an evaluative and comprehensive research into innovation processes, (ii) elaborating "bottom-up" approaches giving special consideration to innovations instigated by stakeholders and brought to fruition under real-life conditions, (iii) breaking from standardization by thinking from the outset of the adaptability of innovations and, finally, (iv) tying in the experimental approach with a decision-making process.
