[Local, central and regional functions. Obsolete concepts?].

As a consequence of the regionalization of the health services in Norway hospitals were given either local, central or regional responsibility. This system was intended to improve the availability of expertise and costly equipment, and at the same time reduce the growth of expenditures on health care. In the last few years, however, many of the smaller hospitals have improved their technical and medical skills to such an extent that this classification system has become less meaningful. Aker hospital in Oslo carries out local, central and regional functions. In a prospective study at this hospital we found that 88% of 980 consecutive medical admissions could be classified as local hospital admissions. Only 5% of the patients needed service at the central level, and 5% at the regional level. In our opinion it would suffice to have two types of hospital ("treatment levels"), standard hospitals and referral hospitals.
