Consider a Hypothetical Example in Which a Patient Has a Condition

Consider a hypothetical example in which a patient has a condition in which she can expect to live only 2 more years on medications, with her quality of life reduced to 50% during those 2 years. With successful surgery as an alternative, she can expect instead to live 3 years with a better quality of life, 90%. Surgical mortality rate is 1% and the surgery is successful half the time. Using a 5% time discount rate, a student in health economics class correctly sets up the analysis.

A) 2.58.
B) 1.77.
C) 0.98.
D) 0.79.
