Patient education is considered to be a major feature of medical rehabilitation in chronic disorders. The rehabilitation sciences research programme funded by the German Pension Insurance scheme and the Federal Ministry of Education and Research comprises a considerable number of evaluation studies carried out with methodological rigor. Over two funding periods, patient education programmes were developed and evaluated with respect to their medical, psychosocial, occupational and economic effects. In this article, a conceptual definition of patient education is presented. Then, the aims and results of ten patient education studies of the funding programme as well as of several implementation projects are described. When integrating these results into previous research taking both a national and international perspective, it can be concluded that patient education programmes are effective regarding medical psychosocial and socio-economic outcomes, although effects sizes may vary. However, in some disorders the state of the research is still unsatisfactory and results are either scarce or heterogeneous. In particular, it is unclear whether such programmes are widely used in medical rehabilitation on a routine basis. Several education programmes provide train-the-trainer opportunities, others are still in the process of development or evaluation. Implementation projects such as those described in the article are aimed at closing these gaps and disseminating research results into the practice of rehabilitation.
