Initiation, Switching, and Cessation of Psoriasis Treatments Among Patients with Moderate to Severe Psoriasis in the United States.

Background: Psoriasis patients frequently switch among multiple therapies while managing their psoriasis. Determining treatment transitions is fundamental to understanding how patients access and use treatments.

Objective: We aimed to identify patterns of treatment transitions of US patients with moderate to severe psoriasis over 5 years.

Under-Treatment of Patients with Moderate to Severe Psoriasis in the United States: Analysis of Medication Usage with Health Plan Data.

Introduction: Psoriasis is a chronic inflammatory disorder with significant morbidity and mortality, but a persistent gap appears to exist for the adequate treatment of patients with moderate to severe disease. As the extent of under-treatment is unknown, we attempted to determine overall treatment patterns and estimate under-treatment using a large database.

Methods: Data from the US National Health and Wellness Survey was used to estimate the proportion of patients with mild, moderate or severe psoriasis.
