Dermatologist preferences for first-line therapy of moderate to severe psoriasis in healthy adult patients

Background: Despite increasing therapies for moderate to severe psoriasis, dermatologists' treatment preferences are unknown. Objective: We sought to assess dermatologists' preferences for first-line treatments and their selection determinants. Methods: We surveyed 1000 US dermatologists (500 National Psoriasis Foundation and 500 American Academy of Dermatology members who treat psoriasis) about their preferences for first-line treatment of moderate to severe psoriasis in healthy adults of childbearing age using standardized patient vignettes. Results: The response rate was 39% (N = 387). Preferred therapies for male and female patients were: ultraviolet (UV) B (40% and 56%, respectively), etanercept (15% and 19%), methotrexate (16% and 4%), and adalimumab (12% and 10%). Of respondents, 66% administered phototherapy in their practice. After adjusting for all physician characteristics, those preferring first-line UVB for male or female patients were significantly more likely to have phototherapy in their practice (odds ratio [OR] 3.4, 95% confidence interval [CI] 1.8-6.6 and OR 2.8, 95% CI 1.5-5.3, respectively) and to have used UVB in more than 10 patients in the last 3 months (OR 8.0, 95% CI 3.9-16.4; OR 9.6, 95% CI 4.3-21.6). Dermatologists in the Midwest were more likely than those in the Northeast to prefer adalimumab first line for male and female patients. Limitations: We surveyed only dermatologists with interest in treating psoriasis and elicited their treatment preferences for a single base case scenario. Treatment preferences may differ between survey respondents and nonrespondents. Conclusion: UVB is most commonly preferred as a first-line treatment for moderate to severe psoriasis in healthy adults, and preferences vary based on region, phototherapy availability, and prior treatment use.
