Physicians consider the information provided by Norwegian DICs on drug use during pregnancy to be of high quality and of significant clinical impact. The DICs were ranked highest as a source of information among GP, suggesting that the need for prescribing support is influenced by the workplace.

The results of this study show considerable differences between two Norwegian sources providing advice on the use of drugs in pregnancy. Based on the knowledge that healthcare providers choose sources of information in a random manner, our results may be of clinical importance. We believe that the problem with heterogeneous drug information on this subject is not confined to Norway and that our results should be of international interest.
