Analysis of Correlations between Patient-Oriented SCORAD (PO-SCORAD) and Other Assessment Scores of Atopic Dermatitis Severity and Quality of Life

Objective: Self-assessment scores such as the Patient-Oriented Scoring of Atopic Dermatitis (PO-SCORAD) index being recommended by public health authorities for chronic disease management, we aimed at analysing correlations between PO-SCORAD and physician and patient assessment scores of atopic dermatitis (AD) severity and quality of life. Methods: We perfomed an observational study conducted in 12 European countries in 4,222 atopic patients aged 1 month and prescribed Exomega (R) emollient cream. AD severity was measured by the SCORAD index, PO-SCORAD, Patient-Oriented Eczema Measure (POEM) and Self-Administered Eczema Area and Severity Index (SA-EASI) scales, and patient and family quality of life by the Dermatology Life Quality Index (DLQI) and Dermatitis Family Questionnaire Impact (DFQI) scales, respectively. Their correlations were analysed. Results: PO-SCORAD was the only self-assessment score to be highly correlated with the SCORAD index and POEM (r >= 0.70). It was also the best correlated with the DLQI (r = 0.67) and DFQI (r = 0.56). After a 5-week treatment, SCORAD index and PO-SCORAD severity scores had decreased significantly by 60 and 56% (p < 0.0001), and quality of life had improved. Conclusion: PO-SCORAD is better correlated with quality of life scales than other self-assessment scores. (C) 2014 S. Karger AG, Basel
