Evaluation of Health Care Financing Dr. Kyaw Swa Mya Lecturer/Head Environmental Health Department University of Community Health
Outline of Presentation • Why health care financing? • Overview of health care financing • Evolution of health care financing at various stages of economic development • Criteria for evaluation of health care financing KSM, UOCH
Why is health care financing an important subject? • Health care is a basic necessity • Many poor cannot afford illness cost • Medical cost for treating serious illness are beyond the financial means of most households • Many households face bankruptcy when serious illness strikes KSM, UOCH
Philosophical Reason • Egalitarian philosophies – emphasizes equity, particularly equal access to health care and views health care as fundamental necessity for human well being • Utilitarian philosophies – views health in the context of how health contributes to a nation’s welfare KSM, UOCH
Policy Reason • The amount of financial resources mobilized for health care and how they are used depend on health care financing policy • Financing is the principle instrument with which to determine resource flows, distribution of resources, and incentive structures for health providers KSM, UOCH
Policy Reason • Unless a nation has a rational and integrated financing policy, the health care costs of elderly, disabled, and less healthy persons are left for the government to finance and the cost become a heavy financial burden on the treasury • Determine who will have access to basic health care, what services are offered, and their quality KSM, UOCH
Market Failure Reason • The distribution of health risks are highly skewed and it caused two serious market failures in private insurance market • Adverse selection – high risk individual more likely to purchase insurance • Risk selection – insurers exclude high risk individuals and only insure healthier persons for maximum profit KSM, UOCH
Macro-environmental Reason • Economic changes – reduction of government spending in public sector • Demographic changes – significant increase in the population as a whole and of those over age 60 • Epidemiological changes – double burden? Triple burden? • Political changes – increased demand and government supply KSM, UOCH
Six Building Blocks of a Health System Purposeful change aimed at improving health system performance for: System Inputs Source: Strengthening Health Systems to Improve Health Outcomes, WHO’s Framework for Action – WHO 2007 KSM, UOCH
Overview of HCF KSM, UOCH
HCF policy goals (WHO report, 2000) • Financial protection • Equity in finance • Equity of access • Transparency and accountability • Quality care and efficient service delivery • Administrative efficiency KSM, UOCH
Three basic principles for HCF • Principle 1 – Raise enough revenues to provide individuals with a basic package of essential services and financial protection against catastrophic medical expenses caused by illness and injury in an equitable, efficient, and sustainable manner • Principle 2 – Manage these revenues to pool health risks equitably and efficiently • Principle 3 – Ensure the purchase of health services in ways that are allocatively and technically efficient KSM, UOCH
Functions of HCF • Revenue collection • Polling resource • Purchasing services KSM, UOCH
Methods of HCF • Government revenue e.g. general tax, inflation, earmarked tax • Social and private insurance • User fees (OOPs) • Community financing KSM, UOCH
Exchange Model • Bilateral exchange model for goods Money Consumers Providers Service KSM, UOCH
Exchange Model • Trilateral Exchange Model for Goods Taxes Treasury Financing Organization Payments Premiums Services Consumers Providers User’s fee KSM, UOCH
Evolution of Health Care Financing at Various Stages of Economic Development
Criteria for Evaluation of HCF • Equity – in financing - in provision of health care • Efficiency – in financing - in provision of health care • Other criteria – quality, sustainability, risk pooling KSM, UOCH
Definition of Health Equity The International Society for Equity in Health (ISEqH) defined equity in health as “the absence of systematic and potentially remediable differences in one or more aspects of health across populations or population subgroups defined socially, economically, demographically, or geographically” KSM, UOCH
Difference of inequity and inequality • Health inequalities are differences in health that are “avoidable,” “unjust, and unfair” Whitehead 1990 KSM, UOCH
Determinants of Health Inqualities Generally perceived as unavoidable or fair Generally perceived as avoidable or unfair 1. Natural, biological variation 2. Differential health-damaging behavior that is freely chosen 3. Differential health-promoting behavior that is freely chosen 4. Differential health-damaging or health-promoting behavior, where choices are restricted 5. Differential exposure to unhealthy, stressful conditions (home, work, etc…) 6. Inadequate access to basic social and essential health services 7. Health-related social mobility KSM, UOCH
Vertical and horizontal equity • Horizontal equity applies to people in the same status or situation, and people who are alike should be treated in the same fashion, • in other words, equal treatment for equal need • Vertical equity focuses on the difference between individuals or groups of people, and people who are unlike in relevant respects (e.g. income, health needs), and states that the differences should be treated differently in a just way KSM, UOCH
How to measure equity? • Lorenz curve • Gini coefficient • Kakwani index • Concentration index KSM, UOCH
Lorenz Curve • Lorenz curve is a graphical representation of the proportionality of a distribution (the cumulative percentage of the values). It was developed by Max O. Lorenz in 1905 for representing income distribution KSM, UOCH
Lorenz Curve KSM, UOCH
Gini Coefficient Note: Gini Coefficient is a tool for measuring inequality of income. The value of Gini coefficient ranges from 0 to 1. A low Gini coefficient indicates more equal income or wealth distribution, while a high Gini coefficient demonstrates more unequal distribution. KSM, UOCH
Gini Coefficient KSM, UOCH
The Kakwani index Is defined as twice the area between the concentration curve of health payment and the Lorenz curve of household income The value of the Kakwani index ranges from -2 to 1 A negative Kakwani index value indicates the regressive nature of health care payments In contrast, a positive value indicates the progressive nature of health care payments KSM, UOCH
The Concentration Curve and Index The concentration curve graphs on the x-axis the cumulative percentage of the sample ranked by living standards, beginning with the poorest, and on the y-axis the cumulative percentage of the health service use corresponding to each cumulative percentage of the distribution of the living standard variable The concentration index is a means of quantifying the degree of income-related inequality within a specific health variable, for example, health service use, and government health subsidies KSM, UOCH
The concentration index • is defined as twice the area between the concentration curve and the line of equality (the 45-degree line running from the bottom-left corner to the top-right) • In the case where there is no income-related inequality, the concentration index is zero • The index takes a negative value when the concentration curve lies above the 45-degree line of equality, indicating disproportionate concentration of health service use or other health variables among the poor, and a positive value when it lies below the 45-degree line of equality KSM, UOCH

Efficiency Measures Overview It is organized in three tiers Function of Health system esp in Health Care Financing 1. Perspective 2. Output Revenue collection, risk pooling, purchasing Allocative, Technical/ Productive and Social Efficiency 3. Type of Efficiency KSM, UOCH
Efficiency Overview Society Health Care Financing Perspective Health Plans Providers Purchasers Individuals Output Revenue collection, Risk pooling Purchasing Technical Productive Type Social KSM, UOCH
Allocative Efficiency A firm achieves technical efficiency when it cannot produce the same output with any fewer inputs KSM, UOCH
Technical/Productive Efficiency A firm achieves productive efficiency when it cannot produce the same output at a lower cost KSM, UOCH
Social efficiency • Social efficiency is more often the focus for society than for firms and mainly consider for social inclusion • No person can be better off without making somebody worse off (Pareto optimality) KSM, UOCH
