Question

. In the U.S. - there are 200 cardiac arrests per year on the 5,000 passenger aircrafts in service - installing an automated external defibrillator (AED) on a single plane and training crew to use it costs $3,000 annually - if a plane has an AED on board then 16% of those who have cardiac arrest survive (where survival means resuscitated, sent to hospital and then discharged from hospital and for simplicity we ignore hospital treatment costs) compared to a 1% survival rate if no AED is on the plane. - survivors live on average 10 years - on average survivors enjoy a quality of life of 0.5 (on a 0-1 scale) - a year of life in perfect health is valued to be worth $80,000. (a) Calculate the cost of AEDs per year of life saved. (b) Calculate the cost of AEDs per QALY. (c) Does a cost-benefit analysis support installing AEDs on U.S. aircraft? Explain your answer

Explanation / Answer

Live saved per year = 200 x 16% = 32 lives

a) Cost of AEDs per year of life saved = ($ 3000 * 5000 planes) / 32 = $ 468,750

b) Cost of AEDs per QALY = $ 468,750 / 0.5 = $ 937,500

c) Value of additional lives saved = (200 x 15%) x 10 years x $80,000 x 0.5 = $12,000,000

Cost of installation of AEDs = $3000 x 5000 Planes = $ 15,000,000.

Pure cost-benefit analysis suggests, it is not beneficial to install AED as cost of AED per annum is $ 15,000,000 and value of additional lives saved is  $ 12,000,000. However, apart from pure financial perspective, it is important to consider that human life is always worth more than just financial value (human capital) due to emotional and other factors.
