The NHS bases their cost-effectiveness calculations on the increase in quality-adjusted life years that the treatment is expected to add. That measure will absolutely prioritize treatment of younger patients over treatment of older patients because there is more time over which the benefits of the treatment can be realized. Paying hundreds of thousands of dollars to save a ten-year-old from cancer will be accepted because it could add decades to their life. Paying hundreds of thousands of dollars to save a ninety-year-old from cancer will not because it is unlikely to increase their lifespan very much.
