Access to primary healthcare remains a critical challenge in Africa, particularly in underserved areas. This paper evaluates the mutti+ digital health (MDH) solution-a pharmacy-first model providing outpatient services through community pharmacies for 14 prevalent diseases. Using system dynamics modeling, we analyzed three policy options to ensure sustainability, focusing on leadership and policy alignment. Our model identified critical factors affecting sustainability, such as patient adoption, operational costs, NPS, and service utilization rates.
