Abstrakt:	Background: Psoriasis treatments and therapeutic response as they relate to private versus public patient insurance in the United States have not yet been reviewed. Improved understanding could clarify factors challenging optimal psoriasis management and offer insight for dermatologists treating psoriasis within our healthcare system. Methods: 258 subjects were included from a database of psoriasis patients seen at Tufts Medical Center (Boston, MA) during 2008-2014. Insurance was classified as primarily private or public (Medicare or MassHealth/Medicaid). Patients required a minimum of two consecutive visits per treatment and at least 8 weeks within one of four treatment categories: biologics, oral systemics/ phototherapy, combined biologics and oral systemics/phototherapy, or topicals only. Primary endpoint was the Simple-Measure for Assessing Psoriasis Activity (S-MAPA) calculated by multiplying Physician Global Assessment by Body Surface Area. S-MAPA<3 constituted absolute clearance. Insurance type was evaluated as a predictor of prescribed treatment categories, maximum S-MAPA improvement from baseline, and total drugs used per treatment course (“drug-switching”). Results: 80.2% (n=207) and 19.8% (n=51) had primarily private and public insurance, respectively. 69.6% with private insurance were prescribed biologics versus 66.7% (public insurance) (P=0.689). 54% (private) versus 49% (public) achieved clearance (P=0.514). However, S-MAPA decreased 78.35% from baseline in those with private insurance compared to 61.48% (public) (P=0.036). On average, privately insured patients used at least twice as many same-category treatments, most commonly biologics, than publicly insured individuals (P=0.003). Drug-switching was significantly associated with clearance (P=0.024). Multivariate analysis demonstrated no significant differences in prescribed treatment categories, drug efficacy, clearance, S-MAPA, or drugswitching with respect to patient age. Conclusions: Treatment categories were comparably prescribed between insurance subgroups. However, privately insured patients achieved significantly greater degrees of clearance and switched between more medications within biologic and systemic categories, potentially explaining their overall improved therapeutic response. Further studies including cost-analysis could clarify any difference in the effectiveness of prescribed therapy for these two patient populations.
