Iraq had developed a centralized free and universal healthcare system in the 1970s using a hospital based, capital-intensive model of curative care. The country depended on large-scale imports of medicines, medical equipment and even nurses, paid for with oil export income, according to a "Watching Brief" report issued jointly by the United Nations Children's Fund and the World Health Organization in July 2003. Unlike other poorer countries, which focused on mass health care using primary care practitioners, Iraq developed a Westernized system of sophisticated hospitals with advanced medical procedures, provided by specialist physicians. The UNICEF/WHO report noted that prior to 1990, 97 percent of the urban dwellers and 71 percent of the rural population had access to free primary health care; just 2 percent of hospital beds were privately managed.
