Health care systems | B1 4) selective and efficiency driven cost-effectiveness analysis; and 5) public sector failures. It would be impossible to provide a detailed chronological or historical account of how health care systems have been undermined in recent decades, not least because the ways in which health care systems have developed or deteriorated have varied from country to country. However, the wide-ranging factors and policies that have undermined the PHC Approach are discussed so as to produce guiding principles for health care systems development in the future. The chapter then sets out in section 3 a case for the central role of governments and the public sector within health care systems, and concludes by outlining an agenda of principles and priorities for the revitalizing of health care systems in section 4. 1 Remembering Alma Ata and the Primary Health Care Approach The Alma Ata Declaration, sponsored by WHO and UNICEF, arose from the observation of failings in health care systems, as well as the positive results from health programmes in countries such as Nicaragua, Costa Rica, Guatemala, Honduras, Mexico, India, Cuba, Bangladesh, the Philippines and China (Commission on the Social Determinants of Health 2005). The term ‘Primary Health Care Approach’ came to be associated with the health care elements of the Declaration and can be summarised as follows: • First, it stresses a comprehensive approach to health by emphasizing ‘upstream interventions’ aimed at promoting and protecting health such as improving household food security, promoting women’s literacy and increasing access to clean water. This places a greater emphasis on preventive interventions and counters the biomedical and curative bias of many health care systems, and promotes a multi-sectoral approach to health. • Second, it promotes integration – of different clinical services within health facilities, of health programmes and of different levels of the health care system. This recommendation was partially in response to the limitations of ‘vertical’, stand-alone disease control programmes and to the observation that hospitals in many countries were not adequately involved in strengthening primary-level health care. • Third, it emphasizes equity. This recommendation would, for example, aim to correct the neglect of rural populations, as well as socially and economically marginalized groups, within many health care systems. • Fourth, it advocates the use of ‘appropriate’ health technology, and health care that is socially and culturally acceptable. 56
Box B1.1 Countries in decline – health and health care in Africa, the former Soviet Union and Afghanistan Life expectancy in many Sub-Saharan Africa (SSA) countries has now dropped below 50 years. Much of this is due to HIV/AIDS, fuelled and compounded by high levels of poverty, food insecurity and conflict. While the burden of disease has been increasing, health care systems have been deteriorating. The best evidence of this is stagnating or decreasing rates of child immunization and maternal mortality – two indicators that are particularly sensitive to the functioning of health care systems. Immunization coverage rates peaked at 55% in 1990 and stagnated throughout the 1990s. By 2000, only 53% of children in the SSA region were immunized against diphtheria, tetanus and whooping cough (WHO, UNICEF and World Bank 2002). Of 41 SSA countries, only six had maternal mortality ratios of less than 500 per 100,000 live births in 2004 (UNFPA 2004). In 35 countries, at least one woman died for every 200 live births. Seventeen countries had a maternal mortality ratio of 1000 or more – one death per 100 live births. In 12 countries, the maternal mortality ratio worsened between 1994 and 2004 (UNFPA 2004, WHO, UNICEF and UNFPA 2001). In all 15 of the new republics of the former Soviet Union, life expectancy at birth fell between 1990 and 2000. Although there are several reasons for this reversal of human development, an underlying problem has been the effects of post-Soviet political and economic change upon the health care systems of these countries (see: http://www.ghwatch.healthformersoviet union) More than 20 years of conflict have contributed to the destruction of Afghanistan’s health care infrastructure (Waldman and Hanif 2002). In 2002, 60% of Afghans had no access to basic health services and two-thirds of Afghanistan’s districts lacked maternal and child health services (Transitional Islamic Government of Afghanistan 2002). The maternal mortality ratio is 1600 per 100,000 live births – every 20 to 30 minutes a woman dies because of pregnancy-related complications (Ahmad 2004). The government has very weak institutions and a lack of both military and administrative control in large parts of the country which remain under the control of warlords and local commanders (World Bank 2004). • Fifth, it emphasizes appropriate and effective community involvement within the health care system.
