[Patient education in rheumatologic care--a review].

Patient education is a medical intervention for patients with chronic diseases to increase knowledge of their disease, self-efficacy, self-management and consumer behaviour. The goal is to improve their disease outcome, social participation and quality of life. This article reviews concepts, modalities and knowledge on effectiveness of patient education. The results of different studies in different rheumatic diseases on efficacy will be summarized including a small number of cost-benefit analyses. Most studies report on significant and relevant improvements of knowledge, self-efficacy and health status. With respect to disease specific outcomes low to moderate effect sizes with a short duration have been observed. Especially good results have been reported when physical training or other methods of rehabilitation were included. There are marked improvements in consumer behaviour of health measures and sickness leave. A better understanding of information needs and baseline characteristics of patients is necessary to develop more appropriate educational interventions focussed on relevant outcomes that can be improved by educational measures.
