Clinical Decision Support
Ideally, physicians should have a reference book at their disposal that evaluates current and high-quality literature on clinical topics, offers a good search function, and informs them by e-mail about thematic updates. The library has been licensing DynaMed for this purpose for several years for the entire UMM, including app use (the most well-known product of this kind is UpToDate, but it is also very expensive).
In the freely accessible ACCESSSS database, you can search for collaboratively assessed and annotated studies and systematic reviews from about 120 top journals and create e-mail alerts by subject areas.
The "Evidence-Based Medicine Guidelines" are a collection of about 1000 clinical guidelines that are regularly updated, supported by more than 4000 evidence summaries of articles from Level of evidence A to D. This database is only accessible free of charge via a search in ACCESSSS.
Trip is a database for searching for high-quality articles (quality filtering and sorting). We do not have a licence, but the Pro version can be personally licensed annually and has some advantages.
Guidelines
On the page Guidelines there are explanations of German (AWMF) and international databases.
