The process of producing our information usually takes several months. During this time, our draft versions are reviewed and revised internally and externally several times. Although we are, of course, not able to please each and every expert and reader, we try to take as many comments into consideration as possible.
Working with support group organizations
When we start working on creating new health information, we speak with representatives from support group organizations related to the topic in order to learn more about the information needs of those who have that condition and about the challenges involved in coping with the disease.
Internal peer review
Experts from other departments of the Institute for Quality and Efficiency in Health Care (IQWiG, Germany) are also involved in the production of our information. For example, they assure the quality of the search for suitable literature, as well as the selection and evaluation of the systematic reviews. The experts in our institute include medical professionals, specialists in the fields of healthcare and natural science, statisticians, psychologists and social science researchers.
External peer review
Comments and testing by users
Before publishing information on our website, we give patient representatives, experts and industrial associations the opportunity to submit comments on our information within four weeks.
Members of IQWiG’s Board of Trustees are asked to give us feedback too. The Board of Trustees includes medical societies, patient representatives, consumer advice centers, associations of dentists, doctors, and psychotherapists, as well as religious institutions, hospitals and the pharmaceutical industry.
Alongside the peer reviews, each article is read by people who are often personally affected by the medical condition in question. This “testing by users” takes place at the Hannover Medical School (MHH, Germany).
After four weeks, the comments from the peer reviews and user testing are then discussed at an editorial meeting, and taken into consideration when we finalize our information.

IQWiG health information is written with the aim of helping people understand the advantages and disadvantages of the main treatment options and health care services.
Because IQWiG is a German institute, some of the information provided here is specific to the German health care system. The suitability of any of the described options in an individual case can be determined by talking to a doctor. informedhealth.org can provide support for talks with doctors and other medical professionals, but cannot replace them. We do not offer individual consultations.
Our information is based on the results of good-quality studies. It is written by a team of health care professionals, scientists and editors, and reviewed by external experts. You can find a detailed description of how our health information is produced and updated in our methods.
