Hospitalization in Patients with Psoriasis: Impact of Biological Therapies on Temporal Evolution.

Background: Psoriasis is an immunomediated disease mostly controlled at the outpatient level, although there is a low percentage of patients that require systemic drugs or even hospitalization for an adequate control. Biological drugs have represented a turning point in its treatment. So far, despite the growing interest in psoriasis and its management with biological therapies, there is a lack of studies focusing on their impact on hospitalization, a relevant issue to patients and to the sustainability of our healthcare system.
