[Evaluation tools for patient information commonly used in Germany--a critical analysis].

The value of instruments for the evaluation of health- or patient information is a controversial issue. This article examines instruments that evaluate information materials on the basis of predefined quality criteria for evidence-based patient information. The aim is to prove whether the instruments commonly used in Germany can be recommended. A review of the literature and an internet search engine search were conducted to identify relevant international systematic reviews and instruments commonly used in Germany. Four instruments were identified for Germany: The quality seals "AFGIS" and "HON" and the checklists "Discern" and "Check-In". These were evaluated on the basis of the predefined criteria. The instruments predominantly address structural aspects. Aspects of content and content presentation are rarely considered. The instruments neglect relevant quality criteria for evidence-based patient information.
