Equity in the usage of biologics for psoriasis in the working poor.

Biologic therapy often produces excellent outcomes for psoriasis; however, their high cost may create a barrier to appropriate usage, especially in the working poor population. This study defines working poor as income below 150% of the federal poverty level and holding or seeking work at least half a year. Our study aims to identify gaps in access to biologic therapy for psoriasis based on working poor status.
