7 Problems resulting from neglected health systems Quality Ignorance/misapplication of proven interventions Fatal mistakes Few provider incentive structures Lack of quality standards Access Limited availability of basic health services A global crisis in human resources for health Uneven availability of medicines and supplies HEALTH SYSTEMS Affordability High out-of-pocket expenditures Impoverishing catastrophic expenses Undeveloped health insurance

10 Today’s presentation The New Challenge in Global Health Following the money – the countries’ own The Rockefeller Foundation’s Strategy
11 Following the Money Relation between spending and health offers important, sometimes counterintuitive insights Health financing – key “control knob” available to policy makers Health financing critical to improve: Risk protection Coverage of services - Health outcomes & Equity Efficiency (and quality) of service delivery
12 Health Freakonomics There is some “right” level of health spending Trying to reach it in poor countries, while reigning on costs in rich countries Modern cost-effective interventions progressively wipe out disease As people grows healthier, age-adjusted health spending eventually declines
13 Health Freakonomics Countries’ GDP and total health expenditure (THE) are tightly correlated (r 2 =0.95). Global data suggest donor spending adds little or nothing to a recipient country’s THE, and research indicates that private sector spending compensates for changes in public budgets. THE rises faster than GDP as economies grow (income elasticity ≈ 1.1). With GDP growing globally at an unprecedented rate, we predict an economic transition of health, immune to cost control, that will bring great challenges and opportunities for health equity. It is important to note that THE does not correlate strongly with HS performance. For example, some poor countries, such as Vietnam and Kenya, achieve much better health outcomes than other countries in the region with the same GDP. These findings suggest that focusing on HS performance, not simply external funding for health products and services, can drive improvements in health outcomes for the poor.

15 What we don’t know is the ‘How?’ How do countries make tax-financing, public delivery work in low income settings? How do countries, with weak capacity, manage the public-private mix in financing effectively? How do countries expand social insurance to rural/poor populations? How do some countries achieve universal coverage and MDGs at low cost?

26 “Baumol’s Cost Disease” 1.The phenomenon arises outside the health market 2.Traditional cost control does not decrease total spending 3.Attempts to do so distort the system and miss opportunities Baumol's cost disease: Labor intensive services, such as health care, face productivity lag - cannot substitute capital for labor as efficiently as the general economy, so the cost of producing them goes up faster than general inflation
27 A new challenge for L&MICs this macro-micro collision course might create a wave of catastrophic expenditures and pull back many into poverty On the macro level (countries), richer countries spend more in health than poorer ones But on the micro level (individuals), the income elasticity of demand goes in the opposite direction. Unless there is social protection or insurance

31 POLICY IMPLICATIONS 1.Don’t fight the transition – cost controls fail to cap total spending. 2.Plan ahead – invest the growth in equity and quality. 3.Get more health “bang for the buck” - improve health system performance 4.Stay the course with the poorest countries – equity is paramount 5.Deal with transnational issues – they will only grow. 6.Recognize the importance of developments outside the health sector. 7.Invest more in action-oriented research and evaluation.

35 Today’s presentation The New Challenge in Global Health Following the money – the countries’ own The Rockefeller Foundation’s Strategy
37 Opportunity for health systems performance and equity The Economic Transition of Health + the epidemiological transition in health + the ICT revolution = unprecedented transformation of health systems and the need and possibility of universal health coverage (access to quality services affordable to all through pre-paid risk-pooled financing)
38 TRANSFORMING HEALTH SYSTEMS RF overarching vision is to harness smart globalization and holistic systems to achieve universal health coverage in the 21st century. The core hypothesis: As globalization advances, new technologies, changing burdens of disease, and increasing health care costs are transforming HS around the world, and there is a window of opportunity to promote strategies that steer this inevitable transformation toward better and more equitable HS performance.
39 WHO Health Systems Framework THS targets strategies for health systems transformation
40 Guiding Principle: Improve health systems performance, not just purchase products or services Vision: Universal Health Coverage THS activities Evidence-based advocacy Professional support for National HS Stewardship Knowledge, capacity and Country demostrations Activities Strategies Country-level capability & new PPPs Enhancing HS Capacity in developing countries Harnessing the role of the private sector in health Leveraging interoperable eHealth systems in global health Fostering HS Research and Agenda setting
41 Intermediate outcomes (3-5 years) Intermediate outcomes (3-5 years) Activities (1-3 years) Strategies Evidence-based Advocacy and consensus building Ministerial academy, HS Network, Country HS data Fostering collaborative Networks and platforms Enhancing HS Capacity in developing countries Harnessing the role of the private sector in health Promoting the design and implementation of interoperable eHealth systems Country-level innovation & replication Health systems a global priority Professional stewardship of health systems in LDCs Integrated eHealth systems in 5 countries Improved private sector engagement in health systems Access Affordability Quality Long-term goals (5+ years) Long-term goals (5+ years) THS Theory of Change Harnessing the transformation of health systems for better performance Fostering HS Research and Agenda setting
42 What will THS look like in the developing world? Improving country HS capabilities Harnessing the private sector Leveraging eHealth Focus: sub-Saharan Africa and South / SE Asia Continue to refine country list to reflect: Country governance and political commitment to universal coverage GDP trends and OOP expenditure as a proportion of THE Evolving partner and donor landscape Rockefeller capacity and other initiatives Log GDP/Capita (PPP, $) U5MR (per 1000) Log GDP per capita versus Child (<5) mortality rate Median U5MR = 29 Median Log GDP/Capita = 3.78
43 What will success look like? Health Systems and Universal Coverage highlighted in the global health agenda Professional stewardship of health systems is occurring in low-and middle income countries Integrated national eHealth systems are in place in select countries Health systems are construed as actively engaging both the public and private sectors There is better and equitable access, affordability, and quality of health services for poor people

49 Why Focus on the Private Sector? The private sector in most developing countries is… Large: A large percentage of health expenditure and provision is already private Growing: Much of the expected growth in overall health expenditures is likely to initially be in the private sector. Neglected: Ministries of health, along with international agencies and donors, tend to focus on the public sector. Madhya Pradesh, India Source: De Costa, 2007
