About 60% of the patients admitted to Rikshospitalet are referred from other hospitals in Norway for more specialized investigations and treatment. In Norway, Rikshospitalet plays an important part with expert knowledge of the treatment of rare and complicated disorders. Rikshospitalet covers the whole country in various fields, including organ and bone marrow transplants, advanced neurosurgery, and treatment of children with congenital malformations. Rikshospitalet is also responsible for health care to the Norwegian Royal Family.
Rikshospitalet had (2005) 585 beds. It is renowned for its architecture. Rikshospitalet merged in (2005) with the Norwegian Radium Hospital to create Rikshospitalet–Radiumhospitalet. The English form of the name was The University Hospital Rikshospitalet-Radiumhospitalet. Later (in October 2007) the notation was changed to "Rikshospitalet HF" (Rikshospitalet University Hospital HF) and that name now covers, what used to be, 12 different governmental hospitals (Rikshospitalet, Radiumhospitalet, Geilomo, Strålesatelitt ved Sykehuset Innlandet, Hjertesenteret i Oslo, Epilepsisenteret SSE, Spesialsykehuset for rehabilitering i Stavern, Voksentoppen, Spesialsykehuset for rehabilitering i Kristiansand, Nordagutu opptreningssenter og kvinneklinikken Føderiket), each with their own specialities, now under the same "branding".
