Optimizing Prevention of Hospital-Acquired Disability Through Multidomain Interventions

The aim of this study is to assess whether a multidomain, multidisciplinary intervention (MDI), enhanced by technological solutions, effectively improves the functional and cognitive status of older hospitalized patients at risk of disability or worsening frailty. Additionally, the study will evaluate the feasibility and acceptability of delivering these interventions remotely via technology after hospital discharge. Participants will: * Receive an MDI during their hospital stay and continue with remote at-home support for 3 months, or receive usual care. * Attend outpatient clinics for follow-up assessment at 3 and 6 months.
