International Dermatology Outcome Measures (IDEOM) Group 2016 New York Meeting: Meeting Summary and Data from the Psoriasis Working Group.

The International Dermatology Outcome Measures (IDEOM) Group was established to develop validated and standardized patient-centered outcome measures in dermatology that meet the needs of stakeholders and can be used in clinical practice as well as clinical research. At this meeting, we aimed to define the final core domain set to be assessed in psoriasis clinical research and to identify which of the current psoriasis assessment instruments appropriately address those domains. Specifically, we sought to ascertain stakeholder input on domain match and feasibility of multiple psoriasis instruments. We presented 19 physician-reported and 23 patient-reported outcome measures at the meeting. Stakeholders anonymously voted on the validity and feasibility of each instrument. Validity was rated as: green (good), amber (fair), red (poor), and white (not enough information). Feasibility was rated as: green (feasible), amber (concerns about some aspects of feasibility), red (not feasible), and white (not enough information). Eighteen physician-reported and 20 patient-reported instruments received a favorable green or amber rating for validity from the majority of voters. Seventeen physician-reported and 19 patient-reported instruments received a green or amber rating for feasibility from the majority of voters. A significant proportion of the psoriasis instruments received a good or fair vote for measuring their intended psoriasis domains in a feasible manner. We will continue to refine our voting methodology and incorporate patient input into our process of defining psoriasis domains and developing validated instruments.
