Chapter Seven Health Systems principled integrated care To meet the formidable challenges described earlier, this chap- ter calls for the reinforcement of health systems to be based on the core principles of primary health care as outlined Alma-Ata in 1978: universal access and coverage on the ba sis of need; health equity as part of development oriented to social justice; community participation in defining and imple menting health agendas; and intersectoral approaches to health. These principles remain valid, but must be reinterpreted in light of the dramatic changes in the health field during the past 25 years. Four important issues that health systems must confront are examined: the global health workforce crisis, in adequate health information, lack of financial resources, and the stewardship challenge of implementing pro-equity health policies in a pluralistic environment

Health Systems principled integrated care Confronting the global health challenges examined in the previous chapters requires health systems to be strengthened. Without this, the health goals described in this report will remain beyond reach. The lessons learnt from past successes, including the skills and strategies developed from the experiences of tackling polio and SARS, must be applied in combating the HIVIAIDS treatment emergency and in working towards the Millennium Development Goals(MDGs). Progress towards these and other objectives will not be sustainable unless specific health targets- including the 3 by 5 target of reaching three million people developing countries with combination antiretroviral therapy for HIviaidS by the end of 2005-support a broad horizontal build-up of the capacities of health systems Despite the health reforms of recent decades, inadequate progress has been made in building health systems that promote collective health improvement. Now, however, fresh opportuni ies are emerging. Health stands high on the international development agenda, and new funds are becoming available for health work in poor countries. Extending health-enabling conditions and quality care to all is the major imperative for health systems. This chapter explores how the values and practices of primary health care, adapted to the realities of today's complex health landscape, might provide a basis for the improvement of health systems. It reviews basic ideas about primary health care and clarifies the concept of the development of health systems that are based on primary health care. It then examines four major challenges facing health systems: the global health workforce crisis; the lack of appropriate, timely evidence; the lack of financial resources; and the stewardship challenge of implementing pro-equity health policies in a pluralistic environment.

Health Systems: principled integrated care It is useful to understand primary health care as involving both core principles and a variable set of basic activities.

Key demographic and epidemiological shifts include ageing populations, the explosion of HIV/AIDS, and the expanding double burden of diseases in low-income and middle-income countries(see the example in Box 7. 2).

For the purposes of this discussion, it is the principles that are most significant (3), including: – universal access to care and coverage on the basis of need; – commitment to health equity as part of development oriented to social justice; – community participation in defining and implementing health agendas; – intersectoral approaches to health. Enduring principles in a changing environment The global, national and local environments in which primary health care values must be translated into action have changed fundamentally in the past 25 years. Key demographic and epidemiological shifts include ageing populations, the explosion of HIV/AIDS, and the expanding double burden of diseases in low-income and middle-income countries (see the example in Box 7.2). Advances in health technology have transformed many aspects of medical practice and raised expectations concerning the types of functions and services that health systems should provide. The institutional context of health policy-making and health care delivery has also changed. Government responsibilities and objectives in the health sector have been redefined, with private sector entities, both for-profit and not-for-profit, playing an increasingly visible role in health care provision. The reasons for collaborative patterns vary, but chronic underfunding of publicly financed health services is often an important factor. Processes of decentralization and health sector reform have had mixed effects on health care system performance (4). The ideas and activities associated with primary health care have themselves undergone changes. In the 1980s, the approach termed “selective primary health care” gained favour. By focusing on the technical challenges of delivering limited basic interventions in poor areas, this strategy encouraged “vertical” programme structures. These programmes produced Box 7.2 Primary care in a changing environment: the “health houses” of the Islamic Republic of Iran The Government of the Islamic Republic of Iran has invested strongly in training health care providers. Primary health care facilities, popularly known as “health houses”, provide an active network staffed by community health workers, or behvarzes, who are trained and regularly supervised by staff from district health centres. The behvarzes provide basic care and advice on many aspects of maternal and child health and common communicable diseases. They also record local health information through the “vital horoscope” data system, which includes information collected during annual household visits. This system provides valuable information for planning services both locally and nationally. There are high levels of community involvement in the delivery of community-based health care; 90% of the population belongs to a health insurance scheme, and some schemes are explicitly designed to protect the poor. Today, the Islamic Republic of Iran faces several challenges to maintaining these achievements in a changing environment. The country’s epidemiological profile has changed, partly as a consequence of the success of the strategy led by primary care. The major burden of disease is attributable to noncommunicable diseases and injuries, though there are some differences between richer and poorer provinces. Urbanization is increasing, with an associated change in lifestyle. The private health sector is increasing. Clinical case management is often not as evidence-based as it could be. A recent study on health financing demonstrated that the financing system is not as equitable as had been thought: out-of-pocket payments are high, and the poor are less well protected from catastrophic health expenditures than they were previously. The government is moving to respond to these new challenges. It is already beginning to reorient the primary health care activities delivered in health houses. Technical guidelines for interventions and training for different cadres of health worker are being reviewed as part of an effort to improve quality of care. There are discussions about a common benefit package, what it should include and by whom it should be provided; specifically, how to involve private providers more effectively in the delivery of critical interventions, both preventive and curative, for example through contracting. The different insurance schemes are being reviewed within a broader analysis of overall health system financing, and there are debates about what sort of organizational arrangements within the public sector would enhance the quality and efficiency of public providers

Principles in a systems perspective This report reinforces an important conceptual shift towards the model of health systems based on primary health care. In a systems perspective, the potential conflict between primary health care as a discrete level of care and as an overall approach to responsive, equitable health service provision can be reconciled. This shift emphasizes that primary health care is integrated into a larger whole, and its principles will inform and guide the functioning of the overall system. A health system based on primary health care will: – build on the Alma-Ata principles of equity, universal access, community participation, and intersectoral approaches; – take account of broader population health issues, reflecting and reinforcing public health functions; – create the conditions for effective provision of services to poor and excluded groups; – organize integrated and seamless care, linking prevention, acute care and chronic care across all components of the health system; – continuously evaluate and strive to improve performance. Intervention across the disease continuum is needed to achieve the comprehensive care envisaged by such a system. To deal with the increasing burden of chronic diseases, both noncommunicable and communicable, requires upstream health promotion and disease prevention in the community as well as downstream disease management within health care services. Two integrated health care models, the chronic care model and its extension – WHO’s innovative care for chronic conditions framework – promote primary health care concepts: intersectoral partnerships, community participation and seamless population-based care. Evidence supports the use of these integrated models as a means of implementing primary health care principles, with demonstrated reduction in health care costs, lower use of health care services, and improved health status (6–9). Linking expanded HIV/AIDS treatment and health care systems development is a crucial challenge. No blueprint exists, but valuable examples are emerging. Since May 2001, Médecins Sans Frontières has provided antiretroviral therapy for HIV/AIDS through primary health care centres in the township of Khayelitsha, South Africa (10). The delivery of HIV/AIDS treatment in a primary health care setting underscores the potential for integration of different types of care and begins to show how scaling up treatment could fit into – and help drive
