During sessions of 90 minutes duration, patients and relatives are educated in basic knowledge on adrenal insufficiency including the correct behaviour in emergency settings. Participants are provided with emergency cards and sets and are trained in self-injection of glucocorticoids. To evaluate the standardized education programme, patients complete three questionnaires (before, shortly after and 6-9 months after the training) at nine endocrine centres. All centres had been certified by the German Endocrine Society for the education programme. Questionnaires assess general knowledge on adrenal insufficiency and document the influence on patients' feeling of security.
