Comparison of assessments of severity and quality of life in cutaneous disease

Abstract

Clinicians are, by profession, capable assessors of severity of disease. Whether from severity they can deduce a patient's Quality of Life (QoL) is debatable. This study compared scores for physician-assessed severity with the corresponding scores for patient QoL, as assessed using Dermatology Life Quality Index (DLQI) questionnaires in 57 dermatological out-patients. Although there was some degree of correlation between the two measures (r = 0.56), interpretation of QoL from disease severity is clinically unreliable. Thus a physician's assessment of QoL requires formal assessment using a tool such as the DLQI.
