The Effect of Drug Vintage on Survival: Micro Evidence from Puerto Rico’s Medicaid Program
Frank R. Lichtenberg, NBER Working Paper No. w10884, 11-18-04

Lichtenberg, a distinguished health economist at Columbia University, examines “micro data on virtually all of the drugs and diseases of over 500,000 people enrolled in Puerto Rico's Medicaid program” and finds that “people using newer drugs during January-June 2000 were less likely to die by the end of 2002” based on the relative age (i.e. vintage) of the medications they were prescribed. Overall, “the actual mortality rate is about 16% (3.7% vs. 4.4%) lower than it would have been if all of the drugs utilized in 2000 had been pre-1970 drugs.”
