IntroductionIntroduction
Universal Coverage Long achieved by most of the
European Union member state Still an unaffordable policy objective
by some nations? Mongolia: the only low-income
developing country to achieve the goal of universal coverage.

mechanism to ensure sustainability

Single-Payer Approach

Single-Payer ApproachSingle-Payer Approach
Viewed as a non-market approach
Market approach Goods distributed on the basis of
supply and demand Price mechanism People can be priced out of the market
Violates equalitarian principle in delivering health care

Single-Payer ApproachSingle-Payer Approach
Canada Advantages of a single-payer
approach (Deber, 2003) Lower cost for universal coverage Avoidance of risk selection
Well embraced on the ground of equity as well as economic efficiency.

Are the health care costs well contained?

Is EQUITY in use of services sacrificed
while costs are contained?

Equity performanceEquity performance
Horizontal equity principle Equal treatment for equal medical need
Index of horizontal inequity was employed Developed by Wagstaff and van Doorslaer (2000) Standardize for differences in need
Proxied by age, gender and common health indicators Negative value indicates a PRO-POOR
distribution

So, is there a trade-off between cost control
and equity?
![Page 23: Is there a trade-off between cost control and equity? - Evidence from a single-payer approach](https://reader035.vdocuments.net/reader035/viewer/2022062519/568151e8550346895dc02245/html5/thumbnails/23.jpg)
Cost control and equity performanceCost control and equity performance
The trade-off between cost control and equity in access to care can be minimized. TAIWAN, through a single-payer
approach, can achieve gains in economic efficiency.
Cost growth well managed. Fair equity performance of the system.
![Page 24: Is there a trade-off between cost control and equity? - Evidence from a single-payer approach](https://reader035.vdocuments.net/reader035/viewer/2022062519/568151e8550346895dc02245/html5/thumbnails/24.jpg)
Reminder…..Reminder…..
Quality issues are not addressed in the equity study. Equity study largely centered upon
whether socioeconomic factors are deterrents to access to care.

Final wordsFinal words
Each health care system has unique features Generalization may not be
applicable.
Exchange of hard-earned experiences may still minimize the chances of painful lessons.
