Private Health Sector Assessment in Ghana is part of the World Bank Working Paper series. These papers are published to communicate the results of the Bank's ongoing research and to stimulate public discussion. The private health sector in Ghana is a large and important sector in the market for health-related goods and services. However, little has been documented concerning the size and configuration of private providers and their contribution to health sector outcomes. With better information about the size, scope, distribution, and constraints of private actors, Ghana's public policy makers could engage more effectively with the private sector. The scope of the Ghana study involved assessing the role of its private sector in the overall health system; considering the potential of the private sector to play a greater role; and identifying ways to improve the public-private interface to increase equity, access, and efficiency in the health system.
