Evidence-based medicine

Evidence: The cornerstone of our information

We strive to provide objective, neutral and scientific information. In 2008 the World Health Organization (WHO) evaluated our methods and confirmed the good quality of our work.

When writing articles, we follow the principles of “Gute Praxis Gesundheitsinformation” (Good Practice in Health Information), which were proposed by the German EbM Netzwerk (Network for Evidence-based Medicine) to set quality standards for producing evidence-based health information.

Our information is mainly based on the results of systematic reviews. Systematic reviews are summaries of the results of all the main studies on a specific medical issue. They play an important role in evidence-based medicine. This is because it's only possible to get a clear idea of how effective a medical intervention is if you consider the results of all the research in that area at the same time. Individual studies are often too small to be able to provide reliable results on their own.

As well as using systematic reviews, we look for qualitative studies. This type of study helps us understand what it's like for people to live with a certain disease, and what it's like for people who are close to them. Qualitative information is collected, for instance in interviews, and then analyzed.

To stay up-to-date, we usually only include systematic reviews that are no more than three years old. This is important because medical knowledge grows rapidly: Every year the results of thousands of clinical studies are published around the world
