International survey on willingness‐to‐pay (WTP) for one additional QALY gained: what is the threshold of cost effectiveness?

Although the threshold of cost effectiveness of medical interventions is thought to be 20 000- 30 000 UK pounds in the UK, and $50 000-$100 000 in the US, it is well known that these values are unjustified, due to lack of explicit scientific evidence. We measured willingness-to-pay (WTP) for one additional quality-adjusted life-year gained to determine the threshold of the incremental cost-effectiveness ratio. Our study used the Internet to compare WTP for the additional year of survival in a perfect status of health in Japan, the Republic of Korea (ROK), Taiwan, Australia, the UK, and the US. The research utilized a double-bound dichotomous choice, and analysis by the nonparametric Turnbull method. WTP values…
