This document describes the CONNECARE project, which aims to develop a personalized connected care system for complex chronic patients. The system seeks to optimize healthcare resources, engage patients, and provide collaborative support to healthcare professionals. It will take a predictive, personalized, preventative, and participatory approach. The CONNECARE consortium is co-designing a novel smart and adaptive integrated care system with professionals and patients, which will be implemented and evaluated in three clinical case studies across different regions. The project aims to reduce costs and improve outcomes for patients with multiple chronic conditions through more integrated long-term care.
