The quality of life gained is the product of life span and quality rating with the new treatment less the same calculation for the old treatment, i.e. (1.25 x 0.6) less (1.0 x 0.4) = 0.35 QALY. The marginal cost of the new treatment to deliver this extra gain is £7,000 so the cost per quality life year gained is £7000/0.35 or £20,000.

With the initial bite to an individual, there is no reaction, but with subsequent bites, the body's immune system develops antibodies. The bites ...
