[Effects of hospital mergers on health economy].
BACKGROUND
Norwegian hospitals have been characterised by increasing activity, expansion of services and increasing costs for a long time. Differences in quality and accessibility have been documented between hospitals in various geographic locations. Transferral of hospital ownership to the state (from 2002) aimed at increasing capacities and improving quality of services, but also at restricting the increase of costs. These goals have only been partly met. The structure of hospital trusts and organisation of services are therefore continuously debated. This literature review aims at examining whether hospital mergers can reduce costs and at the same time increase the quality of services offered.


METHODS
Literature was identified through a Medline search using the terms "hospital", "merger" and "cost saving". The results are summarized and discussed.


RESULTS
Seven original studies of totally 476 hospital mergers (in the USA, Great Britain and Norway) were identified in the period 1982 - 2000.


CONCLUSIONS
The literature indicates that hospital mergers have a potential to reduce costs by about 10 % if the process achieves complete fusion of previously independent organisations, with a more optimal dimensioning of services and development of a common organizational culture. Collaboration between top management and the professional bureaucracy are prerequisites for success. Mergers are associated with a significant risk of unexpected problems and temporary reduced quality of the services.
