Eugenia Amporfu Kwame Nkrumah University of Science and Technology The Progressivity of the Ghanaian National Health Insurance Scheme and the Implications for Achieving Universal Coverage
Universal coverage is achieved in a health system when all residents of an economy are able to have access to adequate healthcare at affordable prices (Currin and James, 2004). Requirements: adequate healthcare healthcare financing system that ensures affordability to care regardless of ability to pay. **
Types of equity in HC financing • Horizontal Equity: people of the same ability to pay make the same contribution • Vertical equity: People of unequal ability to pay make appropriately dissimilar payment for health care – progressivity of HC financing
Why Equity of healthcare? • The ethical justification for equalizing access to health care is health equalizing • Why is health equalizing important? • Necessary for individual to flourish as a human being (Wagstaff and Doorslaer, 2000)
Policy makers find it justifiable to link payment of healthcare with its ability to pay because • Healthcare payments are involuntary item of expenditure which is caused by an unwanted health shock and that society as a whole is willing to share in absorbing the burden (Wagstaff, ___).
The Ghanaian National Insurance Scheme (NHIS) was introduced in 2003 to make healthcare affordable to all regardless of ability to pay • Premium range: 7.20 – 48.00 GHc to ensure equity • Vertical equity • The purpose of this study is to measure the progressivity of the NHIS
NHIS registered members 2009 • Informal adults – 29.4 • SSNIT contributors – 6.1 • SSNIT pensioners – 0.5 • Pregnant women 5.5 • Indigents – 2.3 • Children less than 18 – 49.4 • Adults aged 70 and above – 6.75
Coverage by region • Ashanti region – 70.77 • Greater Accra region 40.3 – lowest in the country
Sources of financing in the NHIS • There are five sources: 2009 • Premium 19.4% • Non SSNIT contributors: 15.6% • SSNIT contributors 3.8% • NHI levy 61.0% • Investment income 17% • Sector budget support 2.3% • Other income 0.2%
NHI levy – borne by all residents: registered and unregistered • Premium – out of pocket payment, important for universal coverage.
Assessing the Progressivity • 1. Examine the share of premium in ATP • 2. Compare shares of premiums payments of proportions of the members ranked by ATP with their share of ATP: i.e. compare concentration curves with the Lorenz curve. • Criterion: if L(p) = L(ATP) -> equity • if L(p) < L(ATP) -> Progressive • if L(p) > L(ATP) -> Regressive
Measuring Progressivity • The Kakwani Index – measures the degree of proportionality (progressivity). • The computation: πK = C – G • Simpler method:
Where σR2 = the variance of R • R = the fractional ranking of premium • hi = the premium paid • ɳ = the mean of premiums paid • yi = the ATP • µ = the mean of ATP
Useful for comparison • Gender • Location • Education • Marital Status
Data Description • Survey data used: Kumasi and Accra • Sample size 1080
Conclusion • Premiums are regressive • Disproportionate contribution by the poor • The degree of regressivity is higher • in Kumasi than Accra • HH with tertiary education • HH with Secondary education • HH is married • Not affected by gender of HH
Implication for universal coverage • Kumasi has a higher patronage than Accra • The educated are more likely to value health and hence less likely to drop out. • The married?
Policy recommendations • Need to increase the cap on premium to increase the amount paid by the rich. • Marital status could be taken into account when setting premiums • Minimize the variation of progressivity across regions.
