Public–Private Partnerships (PPPs) are collaborative arrangements between government agencies and private sector organizations for the planning, financing, construction, management, or delivery of healthcare services. In health economics, PPPs have become an important strategy for improving healthcare financing by combining public responsibility with private sector efficiency, innovation, and investment. They help governments overcome financial constraints while expanding access to quality healthcare services. One of the primary roles of PPPs in healthcare financing is mobilizing additional financial resources. Many governments, particularly in developing countries, face budget limitations that prevent adequate investment in healthcare infrastructure. Through PPPs, private partners contribute capital for constructing hospitals, diagnostic centers, medical colleges, laboratories, and specialized healthcare facilities. This reduces the immediate fiscal burden on governments while ensuring the availability of essential healthcare services. PPPs also improve the efficiency of healthcare spending. Private organizations often possess better managerial practices, technological expertise, and operational efficiency. Their participation helps reduce delays in project completion, minimizes wastage of resources, and improves service delivery. Efficient management enables healthcare institutions to provide better services at lower operational costs, thereby increasing the value obtained from public expenditure. Another significant role of PPPs is expanding access to healthcare services, especially in underserved and rural areas.
