Today, the governments of the Americas, together with organizations like the Pan American Health Organization, are working to extend health care to rural groups, as well as to the urban poor. The task is a difficult one, but health workers are now employing what they call a "multisectoral approach" to improve health services for such underserved people. It means that all sectors-education, agriculture, industry-are directed towards the common task of improving health conditions.
This multisectoral approach was devised after many years of experience of attempting-and very often failing-to solve health problems by the health sector alone. For example, much money and energy went towards increasing the numbers of doctors and hospital beds; the idea was to model health services after the examples of wealthy developed nations. However, as explained by Dr. Fortunato Vargas-Tentori, PAHO's coordinator for health care extension, other factors were found to influence the level of health of the population. They include poor living conditions, unsafe water, malnutrition, and unproductive agriculture. In the face of such conditions, doctors-even if they were available-could do little of lasting good.
