Introduction
The goal of psoriasis (PsO) treatment is to improve quality of life by lessening the extent and severity of the disease. Traditional systemic drugs and biologic agents are used for the treatment of moderate to severe PsO and recent research emphasizes understanding patient goals and preferences for treatment, to improve overall outcomes.
Methods
An online survey was administered to collect data from 500 adult patients with moderate to severe PsO in the USA. Patients were required to have current or previous systemic therapy use and were excluded if aged 75 or older. Data on demographics, disease burden, treatment use, and patients’ treatment goals and expectations were collected. Descriptive and multivariate analyses examined the factors that predict treatment goals. Subgroup analyses were performed for age, gender, severity, comorbid psoriatic arthritis (PsA), location of PsO, and biologic experience. All analyses were conducted using SAS v9.4 and R v3.4.
Results
Of the 500 adult patients included, 71.6% reported moderate PsO. Patients had a mean (SD) score of 62.4 (23.0) for skin pain, 60.0 (26.3) for fatigue, and 6.6 (2.1) for itch on a scale of 0–100, 0–100, and 0–10 respectively. Mean (SD) score for quality of life (QoL), assessed using Dermatology Life Quality Index (DLQI), was 18.3 (7.3), with more than 90% having moderate/very large/extremely large effect on life. The majority of patients considered “keeping skin clear for 2–3 years” (94%), “overall relief of symptoms” (93.8%), and effective in clearing certain areas” (92.2%) as important attributes of a systemic treatment. Overall, patients expected 50% clear skin in about 2 weeks and completely clear skin in about 4 weeks.
Conclusions
Overall, in this study with more than 70% of patients with moderate disease, patients reported high burden of disease and impact on QoL. This study demonstrates the importance of considering patient perspectives in treatment decisions that are critical for optimizing patient outcomes.
