CENPOS is a large-scale digital transformation programme enhancing person-centred care in nursing homes and day centres across Galicia, Spain. Developed by the regional government, it integrates social and healthcare services through an advanced digital ecosystem covering five key areas: clinical support, operational management, telecare, health data integration, and analytics. The system supports over 30,000 people annually and has a direct impact on around 4,000 residents. It includes more than 50 functional modules, from real-time monitoring to medication management. Early results show faster admission notifications (a 60% improvement), greater access to health data (an 80% improvement), reduced errors, and stronger prevention of frailty through increased follow-ups and multidisciplinary evaluations. Supported by EU funds and regional co-financing, CENPOS boosts professional efficiency and user safety while setting a benchmark for scalable, technology-enabled long-term care.
