Psoriasis in the US Medicare Population: Prevalence, Treatment, and Factors Associated with Biologic Use

In the Journal of Investigative Dermatology, Junko Takeshita and colleagues, including Preethi Rao and Jalpa Doshi, look at factors associated with the use of biologics and other treatments for psoriasis. They  analyzed claims from a nationally representative sample of Medicare beneficiaries with Part D drug coverage. The researchers find that Medicare Part D beneficiaries without a low-income subsidy (LIS) had 70% lower odds of having received biologics than those with LIS. Similarly, the odds of having received biologics were 69% lower among black patients compared with white patients.  This study highlights financial and racial barriers to new and expensive technologies.
