A questionnaire for the assessment of pruritus: validation in uremic patients

A questionnaire was constructed for the evaluation and measurement of pruritus. The questionnaire, based on the short form of the McGill Pain Questionnaire, was tested in 145 patients suffering from uremic pruritus and currently undergoing hemodialysis treatment in 3 centers. The newly developed questionnaire proved to be reliable and provided valid data on the sensory, affective and overall intensity of uremic pruritus. The data suggest that uremic pruritus tends to be prolonged, frequently intense and a major source of distress to the patient. Dialysis was not found to influence the pruritus. The questionnaire may also be useful in pruritus secondary to other causes.
