[Towards the development of technologies to improve clinical decision-making: The example of Tadeus]

Although new technologies and artificial intelligence promise to improve mental health care, few scientifically validated applications are available, particularly in French. To address this issue, Centre de recherche de l'Institut universitaire en santé mentale de Montréal founded the Axel Center to accelerate the digital health strategy and to facilitate technological innovation for mental health research and care. The Axel Center thus addresses a tripartite ecosystem composed of research, clinical practice, and entrepreneurship. The purpose of this article is to introduce an example of an application developed in collaboration with the Axel Center and to present how the center can meet the needs of research teams. This example is Tadeus, a bilingual web application that allows mental health specialists and their partners (e.g. family members, caregivers, service recipients) to enter and share data to more rigorously monitor mental health interventions. In addition to presenting the application, the article discusses the challenges that can arise in the development, sustainability and dissemination of such applications, as well as how the Axel Centre can support research teams in overcoming these challenges.
