Organisational reform in healthcare in China: impacts on the social functions of public hospitals.

Public hospital reform in China since the mid 1980s has had detrimental effects on hospitals' social functions, especially the provision of care for poor people. This study of hospitals in Northern China, using a range of economic measurements, indicated that there has been an overall decline in social functions since 1985, especially in secondary and tertiary level hospitals. Reason for this include the increasingly competitive medical market in China and, under the decentralisation reforms, the imperative for hospitals to generate revenue.
