Abstract

Objective To preliminarily validate the clinical usability of the ameliorated Kawashima Itch Scale(Xie-Kawashima Itch Scale) among adult pruritic patients on maintenance hemodialysis. Methods Xie-Kawashima Itch Scale was developed on the basis of Kawashima Itch Scale. Patients were asked to record their pruritus condition according to Xie-Kawashima Itch Scale or visual analogue scale(VAS) during daytime and night for two weeks. The record at the second week was used for analyzing the correlation between Xie-Kawashima Itch Scale and VAS. Results Totally 134 patients were enrolled in this study,among whom 128 entered the final analysis. Xie-Kawashima Itch Scale was positively correlated with VAS(rs=0.832,95% CI=0.810-0.851,P<0.01 for daytime record;and rs=0.848,95% CI=0.828-0.865,P<0.01 for night record). Subgroup analysis also showed similar correlations between different age groups and among different gender groups. Conclusion Xie-Kawashima Itch Scale has good correlation with VAS in patients on hemodialysis,without being affected by age or gender. Thus,it can be a useful tool for the assessment of pruritus in clinical practice and research.
