Recent market-style reforms in the UK National Health Service (NHS) have attracted the attention of health care professionals, managers, and policy-makers from many developing and central and eastern European countries. This article asks how NHS managers and health professionals should react to such international interest. Six key issues have to be considered when introducing market-style reforms into developing and eastern European countries. First, health sector reform should be formulated on the basis of sound research and evidence. We should also take particular care in understanding how efficiency contributes to health policy objectives and the extent to which private management practices are appropriate to the public sector. We should also question the value of international technology transfer and evaluate the experiences of health sector reform in other countries. Last we should look at the way in which health sector reform is formulated and implemented. Here we highlight important questions about the suitability of replicating the UK experience in other countries.
