SEATTLE — With generic prescribing, a little can go a long way. In fact, by using generics 10% of the time, the Medicare Part D program could reduce drug spending by as much as $2 billion, according to an analysis presented at the annual research meeting of Academy Health.
That could be important because the analysis also showed that about 22% of Medicare beneficiaries who used to receive a $600 subsidy for prescription drugs under the previous Medicare program will no longer qualify for a subsidy, and 16%–23% will probably end up in what is called the doughnut hole of Medicare Part D, where they will have no drug coverage, said M. Christopher Roebuck, an economist with CareMark, Hunt Valley, Md., a pharmacy-benefits management company.
To conduct the analysis, Mr. Roebuck and colleagues used data from 37,425 individuals enrolled in Medicare drug discount card programs for at least 6 months, and who had filled at least one prescription. The researchers then assumed those same usage patterns, with some increase in usage when out-of-pocket costs go down, and applied a 3.5% annual rate for inflation.
The enrollees filled a mean of 19 prescriptions per year, 10 for generic drugs and 9 for brand name, for a mean total cost of $849, of which $538 was paid out of pocket.
Depending on the assumption used to estimate how the new coverage might increase use, the analysis suggests that out-of-pocket costs could increase for these beneficiaries by $38 to $187 annually. On the other hand, if the generic prescription rate were increased by 10%, it would save the beneficiaries a mean amount in the range of $41 to $55 in out-of-pocket costs and would decrease the amount spent by Medicare on each beneficiary by $62 to $71.
Extrapolating that to 33 million beneficiaries, Medicare could reduce its spending by about $2 billion annually, Mr. Roebuck said.
