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® 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.
