Quality adjusted life years (QALY) measure the quality and quantity of a person's life, as impacted by a disease or illness. Consider the following: Current U.S. life expectancy is 78.74 years. How is it impacted by each of these conditions (calculate separately): a) disease, with utility value of .7, b) poverty (health inequality) with utility value of .4 and c) drugs/alcohol with utility value of .6? If new meds were introduced for the disease category and were deemed effective, increasing the utility value to .9, what is the benefit in QALY's of the new medication?
