The use of private-sector contracts for primary health care: theory, evidence and lessons for low-income and middle-income countries.

Contracts for the delivery of public services are promoted as a means of harnessing the resources of the private sector and making publicly funded services more accountable, transparent and efficient. This is also argued for health reforms in many low- and middle-income countries, where reform packages often promote the use of contracts despite the comparatively weaker capacity of markets and governments to manage them. This review highlights theories and evidence relating to contracts for primary health care services and examines their implications for contractual relationships in low- and middle-income countries.
