Well-functioning purchasing arrangements allocate pooled funds to health providers, and are expected to deliver efficient, effective, quality, equitable and responsive health services and advance progress toward universal health coverage (UHC). This paper explores how improvements in purchasing functions in three Nigerian schemes-the Formal Sector Social Health Insurance Program (FSSHIP), the Saving One Million Lives Program for Results (SOML PforR), and Enugu State's Free Maternal and Child Health Program (FMCHP)-may have contributed to better resource allocation, incentives for performance, greater accountability and improved service delivery. The paper uses a case-study approach, with data analyzed using the Strategic Health Purchasing Progress Tracking Framework. Data were collected through review of program documents and published research articles, and semi-structured interviews of 33 key informant interviews. Findings were triangulated within each case study across the multiple sources of information. Improvements in benefits specification and provider payment contributed to some service delivery improvements in all three schemes: higher satisfaction with the quality of care in FSSHIP; increased use of insecticide-treated nets; greater prevention of mother-to-child HIV transmission; expanded pentavalent-3 coverage in SOML PforR; and greater service utilization in FMCHP. Resource allocation to public health facilities was enhanced and lines of accountability were better defined. These scheme-level improvements have not translated to system change, because of the small amount of funding flowing through these schemes and the high level of health financing fragmentation. The institutionalization of strategic purchasing in Nigeria to advance UHC will require raising awareness among decision makers, strengthening purchasing agencies' capacity, and reducing fragmentation.
