Abstract
Heart failure is a major cause of death in the Western world and has a severe impact on the functioning status of individuals suffering from it. Self care management involves behaviour and lifestyle changes that reduce the negative effects of this chronic illness. We have developed web-based visualisations for educating patients and promoting behavioural change. The tool uses interactive web graphics to visualise relationships between lifestyle, symptoms, patient parameters and the disease. The goal is to empower and motivate patients to take more control of the disease management process. In contrast to many educational websites with interactive content our application utilises real patient parameters and it has been evaluated from a health psychology perspective. Initial usability studies revealed difficulties with the platform independent design, but that overall the tool was perceived as educational and easy to use. A more detailed study explored the responses of Māori individuals with heart failure and their whānau to a patient education intervention using the tool. Semi-structured interviews, guided by the Common Sense Model of illness representations, demonstrate that the programme promotes knowledge and understanding of the illness and its associated symptoms and promotes protective behaviour.
