Increasing GDR

I love reading healthcare articles which have acronyms that not everyone knows. (Maybe it was defined earlier, but I didn’t see it.)

Another nugget from the Caremark trend report is on programs and plan design components to drive generic dispensing rate (GDR) which is the number of prescriptions filled as generics divided by the total number of prescriptions filled. (Versus generic substitution rate which is the number of prescriptions filled as generics divided by the total number of prescriptions filled for which a chemically equivalent generic is available. I can’t remember whether we used only A-B rated generics or all generics, but that is a technical discussion for another time.)

This is great. It tells you the impact (on average) of implementing a plan design or some of their clinical programs on your GDR. (BTW…a good rule of thumb is that an increase of 1% in GDR is worth about 0.75-1.5% savings in your overall prescription spend.)
