The increase of chronic illness as a leading cause of death has given rise to self-care and expert patient initiatives. Caring for chronically ill people places a tremendous economic burden on the health care system, informal carers, the labour market and benefit system (Department of Health 2001, 2004, 2005). Thus, in many countries health policy encourages patients to become ‘experts’ in the self-management of their conditions in the belief that it will help save money and improve health and well-being (Wanless 2002).
