This paper presents the intermediate results of I.R.M.A. (Innovative Remote Monitoring and Assistance), a project aimed at developing an integrated care service model to support frail older adults over 75 who live alone in social housing buildings in Piacenza (Italy). The project focuses on the co-design of a replicable and scalable model of proximity and community care that integrates commercially available non-invasive monitoring technologies with relational systems and local welfare networks. The co-design process was structured in several workshops involving a multidisciplinary team of local institutions and professionals involved in the development of user profiles, operating protocols, and the definition of customization criteria for the service. The service model resulting from the participatory design process was subsequently tested with a group of 20 older adults. Intermediate results highlight the importance of a relational mediator, the I.R.M.A. care facilitator, to bridge the gap between technological monitoring systems, the needs of users and their care networks, and the activation of local services in their support. Other key insights include the potential of a modular approach to make the service as adaptable as possible to heterogeneous home and care contexts, and the value of co-design in aligning technological tools with constraints imposed by the specific context of implementation. The pilot is ongoing and will run until December 2025. It will collect quantitative results, including the number of support services activated for the older adults involved, metrics of interaction with the I.R.M.A. care facilitator, and data from monitoring systems, as well as qualitative results such as perceived loneliness, sense of safety at home, and familiarity with digital tools.
