Chapter 12: understanding and organizing health care systems. Within the health sector, the element that most affect health are public health activities such as water supply and sanitation, food inspection, vector insect control, disease surveillance, reduction of industrial pollution, and regulation of pharmaceuticals. The organization of the health care system in each country is a reflection of its political trajectory and societal ideas/values. It is also influenced by the international political and economic order. Closely related to this is the fact that hc systems tend to privilege biomedical and behavioural models over the other ones. W/in every country, there is an entity, usually a ministry of health. They may be the dominant provider of medical care, or its main function may be to supervise and regulate the work of other organization. Health policy is usually focused on curative, medicalized care and underemphasizes community, preventive, and integrated services.
