A Trillion-Dollar Question for Global Health
Universal health coverage, ensuring everyone can access quality, affordable health care, remains one of the most ambitious targets of the UN Sustainable Development Goals. As governments around the world struggle to deliver on this promise, many have turned to contracting out health services to private providers. But does this approach actually work? A sweeping global review of more than 80 peer-reviewed studies, conducted by researchers in South Africa, Brazil, and India, offers some nuanced answers.
The review, authored by Zoheb Khan, Frederico Haddad, and Leslie London, examined evidence from countries across multiple continents. Their findings reveal that the success or failure of outsourced health care depends far less on whether services are privately delivered and far more on how contracts are structured, monitored, and governed.
Access Improves, Quality Remains Uneven
One consistent finding was that contracting out often improved access to primary care, particularly in peripheral or remote areas where the state's reach and resources were limited. Private providers were able to extend services to communities that government systems had struggled to serve, filling critical gaps in coverage.
However, the impact on service quality remained inconsistent across studies. The review highlighted a fundamental measurement problem: quality was frequently assessed through narrowly defined targets, such as the number of patients seen, rather than actual health outcomes. This creates a system where providers can meet contractual benchmarks while delivering care that falls short of meaningful standards.
