There are 43 HFs in Norway, each led by a board of directors appointed by the authority. Most HFs are responsible for one or more hospitals, though some are solely responsible for pharmacies. The trusts are regulated by the Health Trust Act of 15 June 2001.
The four Regional Health Authorities each own a pharmaceutical trust, organized as a health trust, that manages hospital pharmacies. But some hospitals instead use commercial pharmacies that are part of the chains. All 33 hospital pharmacies belong to the Ditt Apotek chain, on franchise from Norsk Medisinaldepot. Total revenue in 2006 was NOK 3.5 billion.
