 The paper describes the trial implementation protocol for PROACT, a digital health platform designed to support older adults with multi-morbidities and self-managing their conditions at home, with the involvement of their care network. The study was conducted across two EU member states and involved a 12-month action research trial design, with participants provided with PROACT technologies and CN members given access to an app to remotely support them. Qualitative and quantitative feedback and evaluation data were collected at four time points, and thematic analysis was used to analyze the qualitative interview data. The trial outcomes are at various stages of publication since 2021, with the aim of co-designing and developing a digital intervention that advances self-management of multi-morbidity at home as part of a proactive, integrated model of supported person-centered care.
