Self-reported Versus Physician-reported Severity of Chronic Hand Eczema: Concordance Analysis Based on Data from the German Chronic Hand Eczema Patient Long-Term Management Registry

Abstract

Self-assessment of general health status has a signifi-cant influence on patient-related outcomes. The aims of this study were to investigate and compare the level of agreement between patients’ and dermatologists’ assessments of the severity of chronic hand eczema. From the German registry “German Chronic Hand Eczema Patient Long-Term Management Registry” (CARPE), 1,281 pairs of patients with chronic hand eczema and their dermatologists were included. Of these, 788 pairs ser-ved as a comparison 2 years after baseline. Concordance analyses found that complete concordance between pa-tients’ and dermatologists’ assessments were 16.62% at baseline and 11.47% at follow-up. Overall, patients assessed their chronic eczema at baseline as more severe than did the dermatologists; whereas, at follow-up, patients assessed their condition as less severe than the dermatologists’ assessment. Bangdiwala’s B sho-wed lower values of concordance for womens’ and older patients’ self-assessment with the dermatologists’ assessments. In conclusion, dermatologists should consider the patient’s perspective and the individual’s assessment of their chronic hand eczema in order to provide effective care in clinical practice.
