Dermatology Life Quality Indexprovides different information from PASI

Washington - The Dermatology Life Quality Index (DLQI) is a widely used and validated measure of patient-reported outcomes in psoriasis. Unlike the Psoriasis Area Severity Index (PASI) score, a well-established measure of a patient's disease activity where each area of the body is weighted proportionally to the surface area covered, the DLQI is more heavily influenced by areas of the body that are readily visible, such as the head and lower extremities. "Therefore, the DLQI may provide information regarding outcomes beyond that described by the PASI score," said Alexa B. Kimball, M.D., M.P.H., assistant professor of dermatology at Stanford University.
