Evaluation of Racial and Insurance Differences in Prescription Rates of Systemic Medications for Psoriasis and Psoriatic Arthritis

Background: A prior study of Medicare beneficiaries in 2011 suggested black patients are less likely to be prescribed biologics than white patients. An investigation from Beth Israel Deaconess Medical Center conducted between Jan 2010-Dec 2021 did not find a difference in the prescription rates of systemic medications between black and white patients. This study sought to investigate if these racial disparities were present when looking at data from 2000-2009 or when comparing types of insurance.
