Question

A Merck representative visits your office and tells you that Fosamax (alendronate) will decrease the incidence of repeat hip fracture by 50% over 3 years. That excites you because you have 20 elderly women and 5 elderly men who already have fractured one hip in your practice. You locate the study by Black in Lancet (1996) and find out that fracture occurs in 2.2% of placebo patients and 1.1% of patients on Fosamax

Answer 1

●Total number of years to be treated =3 years

So 1 year =365 days,therefore 3 years=3×365=1095 days

When the daily cost of Fosamax is $4.82

Then for 1 year that is for 365 day (365×4.82=1759.3)

If $1759.3=1 year,then 3 year=5277.9(1759.3×3)

Ans:5278

●The daily cost =$0.23

So for 1 year multiply by 365

=365×0.23

=83.95

Therefore for three years multiply 83.95×3=251.85

Ans:252
