Abstract
Purpose: We sought to compare the impact of biologic versus oral therapies on mental health outcomes among adult U.S. residents with moderate-to-severe psoriasis.
Methods: We performed a nationwide, cross-sectional study comparing 2,303,534 (weighted) adults with moderate-to-severe psoriasis on biologic versus oral therapies and their associated mental health outcomes using the 2003–2015 Medical Expenditure Panel Survey (MEPS). Mental health outcomes were measured with the Kessler 6 (K6), a validated measure of psychological distress, and Patient Health Questionnaire 2 (PHQ2), a screening tool for depression.
Results: The mean K6 score for residents on biologic therapies was significantly lower than that of residents on oral therapies (2.72 [95% CI: 2.27–3.17] versus 3.70 [95% CI: 3.27–4.12]; p < .001). The mean PHQ2 score for residents on biologic therapies was also significantly lower than that of residents on oral therapies (0.540 [95% CI: 0.390–0.690] versus 0.890 [95% CI: 0.749–1.031]; p < .001). Based on adjusted multivariable linear regression models, biologic therapy was associated with significant reductions in K6 (p < .001) and PHQ2 (p = .016) scores compared to oral therapy.
Conclusions: Therapeutic choices for psoriasis impact mental health outcomes. Biologic therapy is associated with reductions in psychological distress and depression as compared to oral therapy in the U.S. adult moderate-to-severe psoriasis population.
