The focus of the Do CHANGE project is on empowering individuals with high blood pressure, ischemic heart disease or heart failure with tools and services to optimally monitor and manage their real-time health condition and disease. The innovative approach of the Do CHANGE project also involves the patients' surrounding health ecosystem in the process. The traditional difficulties of therapy adherence in a physician-centred care system are radically abandoned and replaced by a patient-centred approach. The approach advocated by Do CHANGE project focuses on the needs of the patient by not only providing them with innovative tools that assess the patient's real-time health condition, but also offer a variety of behavioural alternatives. The main hypothesis of the Do CHANGE project is that patients' disease self-management and lifestyle will improve as compared to self-management of patients who receive the care as usual.
