Exchange of information is an important part of health work. What the informer intends to tell and what the patient understands aren’t necessarily the same. The internet has become a widely used information source also when it comes to medical issues. One problem is that internet is an open media, which means that anybody can put anything they want on any issue they want there whitout any quality check on the information. Another is that the amount of information is so large. This study was done in an attempt to find out what kind of information exists on the internet in Norwegian for patients and relatives about neonatal jaundice. 180 internetpages were searched using three different search engines and two different search criteria. Two persons without special knowledge in the medical field looked through the pages to say whether they found them understandable or not. The results where that 37% of the pages where repeated and 43% contained irrelevant information. 5% of the pages were dysfunctional, while 2% contained clear faults. The remaining pages contained good information, but only 8% of the total were in addition understandable without special medical knowledge. This means that only a very small proportion of the information patients find on the internet is actually useful. An even smaller proportion is clearly wrong information but this is still a worse problem because it can be dangerous and spread worry. Health workers should try to inform their patients about sites on the internet with good and reliable information.
