Background: International Dermatology Outcome Measures and the American Academy of Dermatology recently agreed on a physician-reported global severity measure to demonstrate quality of care in inflammatory dermatoses. Objective: Because patient-reported outcome measures are also important, we aimed to achieve consensus on 1 of these measures for clinical practice. Methods: Patients and providers participated in a consensus-building study involving a modified-Delphi technique. Voting was focused on identifying a minimal set of assessments for clinical practice, patient global assessments (PtGAs), Skindex instruments, and final instrument selection for quality improvement. Results: Among 53 stakeholders, >70% agreed that identification of patient goals, assessment of treatment harm, and assessment of the adequacy of treatment response were the minimal assessments needed for clinical practice. The most preferred PtGA was a 5-point PtGA (scale 0-4; 0 = clear, 4 = severe) having an optional check-box for worst ever. A new metric to assess change since treatment initiation, which we called a trajectory measure, was proposed. Stakeholders preferred Skindex instruments over PtGAs and a trajectory measure for clinical practice. Limitations: A small number of patients and caregivers were involved and a consensus was not reached on all items. Conclusion: PtGAs as standalone measures do not adequately capture the patient's assessment of disease severity or the effect of care. The combination of a PtGA with a Skindex instrument or another measure of health-related quality of life might provide a more comprehensive evaluation of patients in clinical practice.
