| Abstract |
The estimates indicate that, in the entire population, a reduction in the age of drugs utilized reduces non-drug expenditure 7.2 times as much as it increases drug expenditure. For example, reducing the mean age of drugs used to treat a condition from 15 years to 5.5 years is estimated to increase prescription drug spending by $18 but reduce other medical spending by $129, yielding a $111 net reduction in total health spending. Most of the savings are due to reductions in hospital expenditure ($80) and in physician office-visit expenditures ($24).
In the Medicare population, a reduction in the age of drugs utilized reduces non-drug expenditure by all payers (i.e. Medicare and various forms of Medicare supplemental insurance, Medicare for dually eligible individuals and Medicare beneficiaries' out of pocket payments) 8.3 times as much as it increases drug expenditure; it reduces Medicare non-drug expenditure 6.0 times as much as it increases drug expenditure. About two-thirds of the non-drug Medicare cost reduction is due to reduced hospital costs. The remaining third is approximately evenly divided between reduced Medicare home health care cost and reduced Medicare office-visit cost.
We also show that Medicare enrollees with private prescription drug coverage tend to use newer drugs than those without such coverage: the mean age of drugs used by Medicare enrollees with private Rx insurance is about 9% lower than the mean age of drugs used by Medicare enrollees without either private or public Rx insurance.
