Italy is one of the main receiving countries of migrant care workers in Europe. Its migrant-in-the-family model has developed since the 1990s, and, today, home-based eldercare is unimaginable without the work of the almost one million care workers employed in private households, of whom over 75% are migrants. Despite forming one of the most important pillars of eldercare provision in the country, the employment of migrant care workers is not addressed in national policy. However, regional policymaking is far from inactive in the face of growing gaps in care as regions and municipalities play a crucial role in regulating, organising, and providing eldercare. With a focus on comprehensive solutions, cross-sector collaborations, and interactive learning processes, social innovation becomes an important element in reforming eldercare in the context of institutional inertia, fragmentation, and permanent austerity. In what ways are regions using social innovation to respond to challenges in eldercare provision and integrate migrant care workers? This study is based on interviews with experts from the region of Tuscany, which is running the project Pronto Badante (emergency care worker). The results suggest several advantages of local interventions breaking with the institutional silo mentality, as well as ongoing challenges regarding the impact and sustainability of these interventions.
