Patient-reported outcomes are important elements of psoriasis treatment decision making: A discrete choice experiment survey of dermatologists in the United States - 16/05/19

Background |
Psoriasis Area and Severity Index (PASI) response rates have been the benchmark for evaluating treatment efficacy in trials involving moderate-to-severe psoriasis.
Objective |
To understand how dermatologists assess biologics and which trade-off rules they apply when planning psoriasis treatment.
Methods |
Two online surveys of 130 and 129 US dermatologists (surveys 1 and 2, respectively) were conducted with use of direct and indirect elicitation via discrete choice experiment. Respondents were asked to choose hypothetical biologics on the basis of 6 attributes (a ≥75% reduction from baseline in PASI score or a ≥90% reduction from baseline in PASI score, infection risk, dosing frequency, and 3 patient-reported outcomes [PROs] [relief of depression, relief of itching, and impact on usual activities]).
Results |
Most dermatologists (74% in survey 1 and 76% in survey 2) reported using both PASI and PROs when selecting a biologic. PASI response rate was the most important attribute (35%-38% of overall decision weight), whereas combined PRO attributes had similar importance (36% of decision weight). Infection risk and dosing frequency influenced the decision to a lesser extent.
Limitations |
Potential bias in considering 3 PROs versus 1 PASI rate and 1 safety attribute.
Conclusion |
PASI is most important for dermatologists selecting biologics, but PROs are also considered, especially when PASI response rate is similar between treatments. PRO data should be collected in trials involving moderate-to-severe psoriasis.
