Iraq had developed a centralised free health care 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 (UNICEF) and the World Health Organization (WHO) 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% of the urban dwellers and 71% of the rural population had access to free primary health care; just 2% of hospital beds were privately managed.
