Question

teffectiveness of influenza vaccination is well established for persons aged 65 years The cost and older. A study considered cost effectiveness and cost-benefit for healthy adalts less than 65 years old. A randomized experiment was run. The treatment group received an influenza vaccination, while the control group received a placebo. Any favorable benefits of influenza vaccination last only for one flu season (a year). We consider the costs and benefits of influenza vaccination for 1,000 adults when per person - The cost of vaccination (including lost work time) is $25. - The cost of influenza illness (including lost work time) is $200. Influenza vaccination reduces the probability of getting influenza from 0.24 to 0.14. (a) Perform a cost-benefit analysis of influenza vaccination. Does it favor vaccination? (b) What is the cost of influenza vaccination per case of flu avoided? (o0 Give a verbal definition of a QALY. (i) What is the advantage of using QALY's compared to cost-benefit analysis?

Explanation / Answer

As per 1000 adults, probability of influanza illness is 0.24

That means ( 1000*0.24 ) 240 peoples got influenza disease if they don't take vaccination.

( 1000*0.14 ) 140 people got influenza if they take vaccination.

Cost if they don't take vaccination = 240*200 = $48000

Cost if they take vaccination = (140*200)+(1000*25)

= $53000

So, by the cost benefit analysis this vaccination is not favourable.

Per adult cost of influenza vaccination = 53000/1000

= $53 per adult

Verbal definition of QALY =

The quality adjusted life year is a generic measure of disease burden, including both the quality and the quantity of life lived.

Advantages of using QALY=

• To maximise the benefits from health care spanding

• To overcome regional variations in access

• To contain costs and manage demand

• To provide bargaining power with suppliers of health care products.
