ABSTRACT
AIM:
To examine the reliability and validity of a modified Chinese version of the uraemic pruritus scale for measurement of different degrees of itching, as well as to identify the predictors for the severity of uraemic pruritus among long-term dialysis patients.METHODS:
Long-term dialysis patients (n = 110) were recruited for a cross-sectional study from a medical centre in Taiwan. A modified Chinese version of the uraemic pruritus scale was used to evaluate sleep disturbance and the severity, frequency and distribution of itching. Reliability was evaluated using item-total correlations, Cronbach's α, and intra-class correlation. Validity was evaluated by the content validity index, predictive and discriminative validity. Multiple linear regression was used on the predictors for the severity of uraemic pruritus.RESULTS:
After optimization for reliability, the scale retained seven items. The Cronbach's α was 0.86, and the results showed that the scale had predictive and discriminative validity. High intact-parathyroid hormone and creatinine clearance rate were important predictors for the severity of uraemic pruritus. The severity of uraemic pruritus was the important predictor for the sleeping disturbance.CONCLUSION:
The modified uraemic pruritus scale can discriminate between patients with a total pruritus score of ≥11 and those with a score of 0 points. The modified Chinese scale is a useful tool for clinically assessing the various degrees of itching among long-term dialysis patients. Our study validates that it could apply to clinical practice in assessment of uraemic pruritus.Palavras-chave
