Globally, the world is moving towards Universal Health Coverage, a concept built around the practical attainment of the basic human rights of health for all. At the most basic level, a Healthcare System is the organization of both human and monetary resources, institutions, and service delivery outlets in order to meet the health needs of a population. These systems come in a variety of models that are influenced by the economic context, the values upon which the system is built and guided, and the socio-cultural context at the national and local levels. This course provides a comprehensive overview of the different models of Health Systems and Service Delivery Organization employed in various contexts around the world as a means of providing a holistic and balanced understanding of how health systems can and do function in different contexts.
