1. Value-based differential pricing, where prices reflect local willingness-to-pay for health and other value elements, is a theoretically robust approach, though many countries currently use therapeutic added value plus price bargaining.
2. Measurement of relative health gain will remain important, but broader definitions of value need further development, moving from listing to measuring to weighting different factors.
3. The UK experience shows measuring broader value factors is possible, but weighting them explicitly makes preferences and social welfare functions clear and may cause backlash without understanding public and patient preferences. A deliberative process combining societal weighting and structured decision-making is needed for fair value assessment.

3. Value Based Differential Pricing
• Health systems have third party
payers acting as agents for
patients and citizens
• Need to act as proxies for
informed citizens
• Health systems should set price
(WTP) for health gain (and other
elements) reflecting enrollees
preferences
• Optimal global R&D comes from
prices reflecting value at local
willingness-to-pay thresholds for
patent duration

6. EEPRU work – approach and findings
• Discrete Choice Experiment (DCE) with 3669 respondents
• Chose whether NHS should treat patient group A or B, who
differed in terms of four attributes: life expectancy without
treatment; HRQOL without treatment; survival gain from
treatment; and HRQOL gain from treatment.
• These attributes were used to explore Therapeutic Improvement
(TI), derive Burden of Illness (BOI), QALY gain and End of Life
(EOL).
• Respondents preferred to treat patients with larger QALY gains,
but at a diminishing rate meaning there was no support for TI
• Respondents preferred to treat patients with a shorter life
expectancy (EOL)
7. Methodology for estimating the wider economic impacts of
health treatments
1. Changes in patient health have wider economic consequences
2. Patients’ wider economic impact: production net of consumption
3. Estimating net production as a function of patient health

Absolute QALY shortfall is total potential health going forwards (Areas A+B+C+D) minus current health
prospects (Area D), i.e. Areas A+B+C.
Proportional QALY shortfall is the ratio of health lost to total potential health going forwards, i.e. Areas
A+B+C as a proportion of Areas A+B+C+D.

But we have different meanings and therefore
measures of equity (Culyer 2015)
a = equity = equal health (45o line from 0)
b = equal health gain (45o line from E)
c = QALY = QALY = QALY, i.e. QALY maximisation
d = maintaining initial distribution of disease
burden (line through 0 and E)
e = distribution in proportion to need (inverse of d)
f = equal shares of resource

14. Conclusions
1. Value-based differential pricing is the theoretically robust way to price drugs
reflecting local WTP for health and related elements of value – the STF is close to
this
» But many countries use Therapeutic Added Value plus price bargaining
2. Measurement of relative / comparative health gain will remain a key focus
3. Work on the broader definition of value needs to continue.
4. Moving from listing the things that matter to measuring them to weighting them
are three very different steps.
5. We need to work on measuring them. The UK experience shows it can be done.
6. Weighting in any form makes the Social Welfare Function explicit and will generate
a backlash
7. It requires better understanding of the preferences of the public and of patients.
8. But a deliberative process is still necessary in value assessment. It cannot be done
by algorithm. Introducing structure to this process (MCDA) is a challenge but also
necessary
9. A fair process is therefore required which combines elements of societal weighting
and a structured deliberative decision making process
