Trends in anticoagulation prescription spending among Medicare Part D and Medicaid beneficiaries between 2014 and 2019.
Researchers examined contemporary direct oral anticoagulant (DOAC) spending patterns within Medicare Part D and Medicaid between 2014 and 2019. They found that, although overall DOAC spending is increasing, DOAC use may be associated with lower downstream medical expenditures compared with warfarin stemming from decreased risk of major bleeding and stroke and reduced drug monitoring.

Specialty drug spending trends among Medicare and Medicare Advantage enrollees, 2007-11.
The authors analyzed trends in specialty drug spending among Medicare beneficiaries ages sixty-five and older using 2007-11 pharmacy claims data. They found that annual specialty drug spending per beneficiary who used specialty drugs increased considerably during the study period, but specialty drugs accounted for less than ten percent of total drug spending per beneficiary. Additionally, in 2011, cost-sharing reductions under the Affordable Care Act significantly reduced specialty drug users' out-of-pocket burden, which decreased 26 percent from 2010.

A simple change to the Medicare Part D low-income subsidy program could save $5 billion.
The authors used an intelligent reassignment algorithm and 2008-09 Medicare Part D drug use and spending data to match enrollees to available Part D plans according to their medication needs. They found that such a reassignment approach, compared to the current approach, could have saved the federal government over $5 billion in 2009.
