Background: Psoriasis is a common and chronic papulosquamous skin disease leading to dissatisfaction and non-adherence to treatment among patients. Dermatologists should identify preferences of patients in choosing treatment options in order to optimize treatment satisfaction, adherence and outcome.
Objectives: To determine patients’ preferences for psoriasis treatments and analyze these preferences according to patients’ sociodemographic and socioeconomic profiles.
Methods: This was a cross-sectional study among adult patients with psoriasis seen at the Outpatient Department of a tertiary hospital, evaluating their preferences for psoriasis treatments based on outcome and process attributes using a self-administered questionnaire. A conjoint analysis determined the most preferred treatment combinations. The validity of correlation was assessed using Pearson’s R and Kendall’s tau.
Results: Among the 62 respondents, the most preferred outcome attribute for treatment was duration of benefit (RIS, 42.72) followed by probability of adverse effects (RIS, 31.29) and magnitude of benefits (RIS, 25.99). Among the process attributes, the frequency of treatment (RIS, 33.34) was regarded as the most preferred, followed by mode (RIS, 26.46), location (RIS, 20.89) and cost of treatment (RIS,19.31). A topical medication taken or applied thrice weekly with cost of less than Php 500, and consulation done at the clinic setting, was the preferred process treatment combination. There were no significant differences in RIS across different sociodemographic and socioeconomic groups.
Conclusion: The findings of this study can give dermatologists guidance on the choice of treatment characteristics for patients with psoriasis that is close to their preferences to ensure good compliance and better outcome
