The Impact of Public Health on Health Systems

Public health is a critical determinant of health system effectiveness, shaping health outcomes and system performance through policies, initiatives, and preventive strategies. This review examines the interconnectedness of public health and health systems, with a focus on two case studies: Ontario’s health units and Uganda’s disease management. It examines the historical evolution of public health, its key components, and the challenges and opportunities in integrating public health into health systems. The findings emphasize that public health initiatives can significantly enhance health system efficiency and effectiveness by addressing broader social determinants of health and fostering community engagement. The review concludes that an integrated approach to public health and health systems can lead to improved health outcomes and long-term sustainability of health systems.
