Plan
• Background
• Cost-effectiveness• Financial protection• Priority to the worse off
• Classification of priority health services
![Page 3: Choosing services Integrating Concerns for Cost-Effectiveness, Financial Protection, and the Worse Off Ole F. Norheim Professor in Medical Ethics and Philosophy](https://reader037.vdocuments.site/reader037/viewer/2022110304/551a6945550346761a8b463b/html5/thumbnails/3.jpg)
Key question
• Should financial protection and distributional concerns be incorporated into decision rules for publicly financed health services?
![Page 4: Choosing services Integrating Concerns for Cost-Effectiveness, Financial Protection, and the Worse Off Ole F. Norheim Professor in Medical Ethics and Philosophy](https://reader037.vdocuments.site/reader037/viewer/2022110304/551a6945550346761a8b463b/html5/thumbnails/4.jpg)
Priority group classification
• Universal Coverage can be defined as access to key health services for all at an affordable cost
1. High-priority services2. Normal-priority services3. Low-priority services
Key
services

How to classify services?
• Cost-effectiveness thresholds< 1 GDP per capita
1-2 GDP per capita
> 3 GDP per capita
(Macroeconomics and Health 2002, WHO CHOICE)
![Page 6: Choosing services Integrating Concerns for Cost-Effectiveness, Financial Protection, and the Worse Off Ole F. Norheim Professor in Medical Ethics and Philosophy](https://reader037.vdocuments.site/reader037/viewer/2022110304/551a6945550346761a8b463b/html5/thumbnails/6.jpg)
Example
• Selected 65 health services from WHO-CHOICE database (AfrE)
• Child health services• Maternal and newborn health services• Infectious disease services• Non-communicable disease services
• Converted all costs to Int $ 2005
(WHO-CHOICE team BMJ series 2005-2012)

Two problems with CEA
• Ignores financial risk protection• Ignores distribution of healthy life years
![Page 10: Choosing services Integrating Concerns for Cost-Effectiveness, Financial Protection, and the Worse Off Ole F. Norheim Professor in Medical Ethics and Philosophy](https://reader037.vdocuments.site/reader037/viewer/2022110304/551a6945550346761a8b463b/html5/thumbnails/10.jpg)
Financial risk protection
• Publicly financed health services provide– Financial risk protection– Health
• Peter Smith : – If no one buys supplementary services, or – a well-functioning voluntary supplementary insurance marketservice selection on the basis of standard cost-effectiveness ratios
will maximize welfare (health + income) (P. Smith, Health Economics 2012)
• When there is substantial out-of-pocket payment for supplementary services, this is not so.
![Page 11: Choosing services Integrating Concerns for Cost-Effectiveness, Financial Protection, and the Worse Off Ole F. Norheim Professor in Medical Ethics and Philosophy](https://reader037.vdocuments.site/reader037/viewer/2022110304/551a6945550346761a8b463b/html5/thumbnails/11.jpg)
• High cost services may be favored over low cost services, at least among services with similar cost-effectiveness ratios.
• My interpretation:– Financial risk protection could act at least as a
tiebreaker for services with identical cost-effectiveness ratios.

Integrating distributive concerns with CEA
• An “Atkinson’s” social welfare function applied to health would judge:– (60, 45) as better than (80, 25)
(Adler, OUP 2012)
• Health prioritarianism would assign higher weights to benefits for B
(Ottersen, JME 2013)

Opportunity cost
• Health prioritarianism
• Knows the cost in terms of DALYs NOT averted
• Can provide reasons for re-ranking:– some priority to the worse off
