The ultimate goal of diabetes care is to enhance the quality of life of people with the condition. Quality of life is increasingly used as a factor in the evaluation of the quality of care. The results of this evaluation are used by health-care providers in order to make recommendations for future care. Only the person receiving care is capable of evaluating their quality of life during and following medical care. In diabetes care, self-report questionnaires are employed in largescale inventory research into the human experience of people living with the condition. While this approach is both logical and positive, HBM van de Wiel and BMJ Wijnberg-Williams emphasize that it cannot replace effective communication between people as a means of understanding the individual needs of each person.
