Translating policy into health outcomes: a mixed-methods health impact assessment of the family physician program in Bonab County, Iran

While the FPP improved some health indicators, its overall effectiveness was constrained by socio-economic inequities, cultural barriers, and managerial inefficiencies. Strengthening the program requires systemic reforms, capacity-building, and addressing social determinants of health. Beyond Iran, this study offers a valuable framework for other low- and middle-income countries facing similar challenges in implementing large-scale primary care reforms, providing insights for optimizing program design and ensuring long-term sustainability.
