Health-Related Quality of Life in Chronic Pruritus: An Analysis Related to Disease Etiology, Clinical Skin Conditions and Itch Intensity

Dermatology. 2015;231(3):253-9. doi: 10.1159/000437206. Epub 2015 Aug 13.

Abstract

Background: It is unknown if health-related quality of life (HRQoL) differs between diseases associated with chronic pruritus (CP).

Objective: To analyze HRQoL in relation to age, gender, skin lesions (primary vs. scratch-induced secondary) and itch intensity.

Methods: Consecutive patients of our itch clinic were assessed with the Dermatology Life Quality Index (DLQI) and visual analogue scale (VAS).

Results: In 510 CP patients (282 females; median age, 61.4 years), DLQI scores and VAS values were highly correlated, irrespective of the type of skin lesion. Overall, women had a lower HRQoL compared to men (females: 10.7 ± 6.7, males: 8.9 ± 6.7), but female gender was only associated with worse quality of life in patients <65 years old.

Conclusion: HRQoL impairment in CP is highly influenced by pruritus intensity but not to the visible skin lesion or underlying cause. With limitations to item bias, DLQI is a suitable instrument for estimating quality of life impairment by CP.
